Description

description

The invention relates to an arrangement for a cover for a vehicle roof, wherein the cover starting from a

Closed position in an open position on a fixed roof element movable, about slidably, is. Arrangements with a movable cover for a vehicle roof are designed, for example, as spoiler roofs, as described in DE 10 2011 018 151 A1. In the so-called

Spoiler roofs is at a rear in an opening direction edge of the lid, first a deployment lever

issued to raise the trailing edge of the lid.

 Subsequently, the lid is moved relative to the release lever in the opening direction. The release lever is held relative to the rest of the vehicle roof and not moved in the opening direction. It is different

For example, in so-called outside sunroofs in which the deployment lever is moved at the rear edge of the lid at least partially together with the lid relative to the rest of the vehicle roof in the opening direction. It is desirable to provide an arrangement for a vehicle roof, which allows a precise opening and closing of a roof opening.

It is described an arrangement for a cover for a vehicle roof, wherein the lid from a closed position to an open position via a fixed roof element

is movable. The assembly comprises a lid carrier for the lid, a fixed guide rail and a along an opening direction in the guide rail slidably mounted on the carriage to move with a

Drive is coupled. Furthermore, the arrangement has a first lifting mechanism which can be displaced along the opening direction and which is pivotably coupled to the lid carrier in the region of a front end of the lid carrier for issuing the lid in the region of the front end. The arrangement has a second displaceable along the opening direction

Lifting mechanism, which is pivotally coupled to the lid carrier in a hinge for exposing the lid in

 Area of a rear, the front end opposite end of the lid carrier. The hinge is arranged in a range of 40% to 70% of a length of the lid carrier from the front end with respect to the opening direction.

The lid is typically mounted to the lid carrier such that movement of the lid carrier corresponds to movement of the lid. Moving the lid into the

Open position takes place in the opening direction. The

Opening direction is for example parallel to the

 Vehicle longitudinal direction. The closed position is the position in which the lid closes a roof opening in the vehicle roof. Here and below applies that the used location information or direction information such as "back" or "front" on the

Vehicle longitudinal direction are related. The vehicle longitudinal direction may also be referred to as a horizontal direction or X direction. Turning off or lifting the lid

or lid carrier takes place substantially in a vertical direction or Z-direction. Under the rear end of the lid carrier is the area to be understood, which faces a rear of the vehicle. Moving the lid over the vehicle-fixed roof element means that the lid is pushed over an outer side of the vehicle-fixed roof element after lifting or exhibiting in the region of a rear edge of the lid, such as the rear end of the lid carrier. In which

vehicle-fixed roof element is, for example, a stationary transparent element, such as a glass cover, or around a part of the roof body, such as the roof or the like. The arrangement thus allows a

externally guided sunroof.

For example, in the closed position, the arrangement is locked, such as blocking or arresting movement of the lid carrier in the X direction. In the closed position, the lid closes a roof opening of the vehicle

Completely .

In an opening operation of the lid carrier from the

Closing position of the carriage (including drive carriage) is moved in the opening direction to the rear, with an X-lock of the lid carrier is released or is first released. In a further method, first an issuing of the lid carrier in the Z direction by means of the second lifting mechanism and thus the lid on a

 Rear edge controlled, with a movement of the lid carrier is blocked in the X direction. This intermediate position is called fan position. Subsequently, the first lifting mechanism coupled to the carriage in a further displacement thereof, so that the lid carrier is raised in the region of the front end, about issued, and taken in the X direction to the rear. This is for example the

Locking of the first lifting mechanism with respect to the X-direction solved. Upon further movement of the carriage, the first and second lifting mechanism and the lid carrier are taken in the X direction rearward in the open position. In the latter, the lid is in the closed position

closed roof opening completely or maximally released.

The fact that the joint between the second lifting mechanism and the lid carrier is not arranged at the rear end of the lid carrier, another mechanical

 Abstützverhältnis achieved in comparison to a linkage of the second lifting mechanism at the rear lid end. In other words, a point of articulation of the second lifting mechanism on the lid carrier in the vehicle longitudinal direction is offset to the front, approximately closer to the first lifting mechanism. In other words, a pivot axis, which is formed by the coupling of the second lifting mechanism with the lid carrier, offset forward. As a result, the second lifting mechanism is not driven so far back when moving the lid in the open position itself. In other words, the

 Lifting mechanism does not cover a long way along the fixed roof element. As a result, lateral guides can be shortened along and / or in the fixed roof element. For example, a slot provided in the vehicle roof for the mechanism can be shortened. This saves on costs, material and production costs.

If the fixed roof element designed as a glass cover, such as a panoramic roof element, so this can contribute to a transverse reinforcement of the vehicle, as a

Cross-connection of the fixed roof element to the rest of the vehicle roof and / or shell is feasible, without a mechanism of the arrangement for moving the lid to to penetrate or cross. Despite reasons of stiffness provided cross-connection, the mechanics can drive up so that the lid in the

desired open position can be moved, for example, to a complete or maximum release of the closable by the lid roof opening of the vehicle roof.

On the other hand, with a correspondingly long lateral guidance along the fixed roof element, it would be possible to extend the lid particularly far to the rear

shift, since the two lifting mechanisms are significantly more compact in their distance from each other with respect to the X direction compared to a linkage of the second lifting mechanism at the rear lid end.

The length of the lid carrier can also be considered as the length of the lid.

The guide rail has one or more guide channels or guides in which the first and / or second lifting mechanism can be guided at least partially displaceable.

Furthermore, the carriage is in a guide channel of

Rail slidably guided. The guides or

Guide channels can be slotted guides, which here and below means an element which predetermines or enforces a trajectory when moving.

The first, front and second, rear lifting mechanism may also be referred to as Ausstellmechaniken. They are mounted relative to the guide rail with respect to the opening direction displaceable. The lifting mechanisms are designed to expose the cover front and rear and / or to take back in the opening direction. These are the Lifting mechanisms coupled to the drive carriage and / or interact with this. The second lifting mechanism and / or the first lifting mechanism can each be coupled to a link, which controls a movement of the first and / or second lifting mechanism.

The first lifting mechanism, for example, by a fixedly arranged on the lid carrier glider or rotary

be formed, in a corresponding stationary

or roof fixed gate is guided and controlled, so that the issuing of the lid is effected.

Alternatively, the lifting mechanisms each have at least one deployment lever that is relative to the guide rail

can be guided displaceably, such as in the guide rail and / or a backdrop. Such a release lever is

for example, indirectly or immediately hinged on

Coupled lid carrier. In this connection, the lifting mechanisms can be referred to here and below as lever mechanisms.

For example, the first lever mechanism has a release lever slidably mounted along the opening direction, which is connected to the lid carrier in the region of the front end of the

Lid carrier swiveling directly to the lid carrier

is coupled.

For example, the second lever mechanism has at least one release lever, which is connected directly rotatable on the lid carrier. With regard to the pivotable coupling of the second lifting mechanism with the lid carrier, it should be noted that a pivot axis between the second lifting mechanism and the Cover carrier is arranged in a pivot point stationary with respect to the lid carrier or the lid.

According to one embodiment, the joint is arranged in a central region of the lid carrier, about 50% of a length of the lid carrier with respect to the opening direction.

For example, the joint is arranged so that this in an operationally mounted state of the assembly

is arranged symmetrically to a vehicle center. As a result, in particular, the advantages explained above and

Functions possible.

According to one embodiment, the second lifting mechanism is formed by a first lever and a second lever, wherein the second lever is pivotally coupled to the carriage and wherein the first lever is pivotally mounted on the second lever and the lid carrier. The back

Lifting mechanism is thus formed by two pivotally connected levers which are pivotally connected in series. In other words, the typically one-piece rear

Release lever by a swivel joint in two components

divided up. This helps to compensate for the lowering of the lid carrier and thus the lid by issuing the front lifting mechanism, such as a front opening lever in time after reaching the fan position. It is thereby contributed to the fact that the rear end of the lid carrier or the rear lid edge does not lower again despite a smaller support ratio. The first lever can also be referred to as a release lever. The second lever may also be referred to as a control lever. The pivotable coupling of the second

Levers with the carriage can be designed as a direct coupling. As a result, the second lever is directly pivotable on Sled stored. On the other hand, an indirect coupling can also be provided. For example, the second lever is mechanically connected or operatively connected to the carriage via one or more additional elements. The coupling is in other words such that a movement of the

Carriage is transferable to the second lever.

According to one embodiment, in the closed position with respect to the opening direction, a joint between the second lever and the first lever is arranged in front of a joint between the first lever and the lid carrier. In other words, the first lever and the second lever form in

Closed position an acute angle, approximately less than 30 °, which is open towards the rear of the vehicle in operation. The

Location refers to the opening direction to the rear. The joint between the first and second levers is thus, for example, closer to a vehicle front facing in

operatively mounted state as the joint between the second lever and lid carrier. For example, the joint between the first lever and the lid carrier with respect to the opening direction is arranged spatially between a joint between the first lever and the second lever and a joint between the second lever and the carriage. According to one embodiment, the first lever and / or the second lever are guided by means of a coupling element in a slot, so that a movement of the lid carrier is controllable in the rear area. When moving the

By sliding the carriage with the second lifting mechanism, ie the first lever, the second one becomes slidable

Actuated lifting mechanism, and thereby forced a trajectory due to the coupling with the backdrop. This allows the trailing edge of the lid a predetermined opening course taking. The coupling element is, as in the following, for example, an engagement element, a

Glider, a rotary glider or the like. According to one embodiment, wherein the gate has a course, in which, in the closed position, a distance of the link to the lid carrier in a first section

enlarged in the opening direction to the rear and in a further, the first section with respect to the

Opening direction subordinate further section again reduced. The subordinate section of the scenery does not necessarily have to be directly adjacent to the first section

connect. For example, after increasing the distance, the distance may initially remain substantially constant, for example only with slight deviations. For example, the scenery here runs parallel to the lid carrier or parallel to the guide rail. Then the distance to the

Reduce the lid carrier again. According to one embodiment, the backdrop is stationary

arranged with respect to the guide rail.

According to one embodiment, the arrangement has a

Locking lever which is pivotally coupled to the carriage and pivotally mounted on the first lifting mechanism, wherein the locking lever is locked in the closed position, a movement of the first lifting mechanism along the opening direction and transferred when moving the carriage from the closed position to a state in which the movement of the first lifting mechanism is released. For example, the locking lever has a coupling element, which is guided in a gate, which has a course that controls the locking of the first lifting mechanism in the X direction. The pivotal coupling with the carriage can be such that an engagement element of the carriage with a trained in the locking lever backdrop

is coupled. This scenery is for example like this

formed so that a course in the closed position releases a relative movement between the carriage and locking lever and then entrains the locking lever in the X direction to the rear after moving the carriage of the carriage and thus the locking of the first lifting mechanism is released.

Alternatively, the backdrop for controlling the second

Lifting mechanism formed in the locking lever.

According to one embodiment, the gate on a course, in which in the closed position, a distance of the link to the lid carrier in a first section

with respect to the opening direction is substantially the same and in one, the first section with respect to the

Opening direction subordinate further section reduced. The slide path runs approximately parallel to the first

Guide rail or parallel to

Opening direction. For example, the second lifting mechanism can thereby be moved parallel to the first lifting mechanism upwards, for example in the Z direction. For example, thereby the second lifting mechanism can be controlled in parallel to the first lifting mechanism such that the cover relative to the vehicle in any position can occupy a space and fluid technically favorable spatial position. For example, this causes the deployment lever of the second lifting mechanism to be moved upwards via a ramp.

According to one embodiment, the second lifting mechanism on a reduction mechanism, which by a third and fourth lever is formed, wherein the third lever is pivotally coupled to the second lever and the fourth lever

pivotable on the third lever and pivotable with the

Sled is coupled. To exhibit the

Lid trailing edge necessary forces are particularly high, since the support ratio by advancing the second

Lifting mechanism away from the rear lid end is changed. The reduction mechanism allows this

to be applied forces by moving the

Slides are transmitted, are reduced. The

 Reduction mechanism thus represents a kind of counterparts.

According to one embodiment, the third lever has a first coupling element, by means of which the third lever is guided rotatably and displaceably in a stationary link.

For example, the third lever by means of

Coupling element in the guide rail, about one

Guideway, parallel to the opening direction. Thereby, the third lever can be moved in the X direction and at the same time, for example due to interaction with another lever or a backdrop, twisted.

According to one embodiment, the third lever has a second coupling element, which is coupled in the closed position with a locking link. The

 Locking link is fixed with respect to the

Guide rail, for example. The locking link locks a movement of the third lever in the

Closed position in the X direction. When moving the

Slides starting from the closed position is the

Lock released and the carriage takes the second

Lifting mechanism including all four levers to the rear with. The locking linkage controls a movement or alignment of the third lever.

According to one embodiment, the carriage

Connecting element on which the fourth lever

is pivotally mounted. The connecting element is coupled to the drive, such as a drive cable, and mounted so slidably on the carriage that for actuating the carriage by means of the drive, starting from the

Closed position, the connecting element is first moved relative to the carriage. Subsequently, the connecting element acts together with the carriage, that in a further displacement of the connecting element of the carriage is taken along the opening direction. The drive carriage is thus extended by the connecting element, with which it together forms a drive unit for controlling the arrangement. The connecting element can also be referred to as a cable connecting element and is preferably formed in one piece.

According to one embodiment, the arrangement is such

designed such that in the closed position, a movement of the

Cover carrier is locked along the direction of opening is the drive of the carriage from the closed position is the

Arrested first. The lock prevents unintentional or unauthorized opening of the sunroof.

According to one embodiment, the connecting element cooperates in the closed position with the lid carrier in such a way that in the closed position, a movement of the lid carrier is locked along the opening direction and the lock is released upon actuation of the connecting element.

For example, the connection element encompasses an element the lid carrier positively, so that a movement of the lid carrier is blocked at least in the opening direction and / or other directions (Y, Z direction). In the present context, a coupling element can be designed as a slider, sliding element, rotary slider or such.

FIG. 1 shows schematically, in perspective, a vehicle roof 2 of a motor vehicle 1. A vehicle longitudinal direction 3 points in the direction of the windscreen or in the direction of a vehicle front. From the front of the vehicle, the vehicle roof 2 extends along an opening direction 4 (X direction, see coordinate system) to the rear. Regarding the

Spatial information applies as I said at the beginning.

The vehicle roof 2 has a roof opening 5 which is completely covered by two transparent covers 6 and 7 in FIG

is closed. The first cover 6, which also front

 Lid is called, relative to the vehicle roof 2 in the opening direction 4 is movable backwards, as later

is described, so that the roof opening 5 at least is partially releasable or can be essentially released in the size of the first lid 6. The second cover 7 is to be understood as a fixed roof element and is firmly connected to the vehicle roof. Alternatively, the second cover 7, a part of the vehicle roof, such as

metallic roofing, be yourself. The first cover 6 can be seen as part of a sunroof, which is a partially externally guided sunroof. For example, the lid 6, 7 is glass lid.

The first lid 6 is made by following

described arrangements of the shown in Figure 1

Closed position, in which it is flush with the vehicle roof 2 and the second cover 7, initially at one

Rear edge 8 raised (issued). This is called

 Designated fan position. Subsequently, the first cover 6 to the rear over the second cover 7 into a

Open position postponed. In this case, a front edge 9 of the first lid 6 is raised. The arrangements comprise two guide rails 10 arranged on both sides, in which, inter alia, the first cover 6 is displaceably supported. A displacement in a guide rail 10 or parallel to this is essentially synonymous with the

Opening direction 4.

Hereinafter, three embodiments of arrangements 11 for moving and exhibiting the first lid. 6

described. Since the arrangements 11 are arranged with the guide rails 10 on both sides, only one each

Arrangement 11 a longitudinal side of the vehicle 1 described. An arrangement 11 can also be used as sunroof or

Ausstellvorrichtung be designated. Furthermore, it should be noted that the first cover 6 fixed with a lid carrier connected is. Moving or moving the first

Cover 6 is therefore equivalent to a movement of the lid carrier. FIGS. 2 to 10 show an arrangement 11 according to a first exemplary embodiment in various states. Figure 2 shows a perspective view from the outside, while Figures 3 and 4 each show a schematic side (cut) views from the inside, approximately from a center of the vehicle 1, and from the outside. In Figures 2 to 4, the closed position of the first lid 6 is shown.

The arrangement 11 comprises, in addition to the first lid 6, a lid carrier 12 which is fixedly connected to the lid 6. Furthermore, a drive slide device 13, a first lever mechanism 14 and a second lever mechanism 15 are provided.

The drive slide device 13 comprises a rear slide 18 with two slide slides 16 and a

 Connecting element 17. The carriage 18 may also have fewer or more sliders. The connecting element 17 is mechanically coupled via a drive cable to a drive, such as an electric drive, so that a movement on the connecting element 17 is transferable. The connecting element 17 is mounted displaceably on the carriage 18, at least within limits, in particular with respect to the X-direction. The connecting element 17 can move along the

Transfer opening direction 4 and the X direction on the carriage 18 so that this over the two

Slide slider 16 in a corresponding guide rail 10 (not shown) can be moved. At one in the assembled state according to a vehicle rear facing end, the connecting element 17 has a locking element 19, by means of which in the

Closed position a corresponding element of

Lid carrier 12, such as a tab (see also Figure 5), is positively embraced, so that movement of the

Lid carrier 12 is locked.

The first lever mechanism 14 has a first deployment lever 20 which is pivotally coupled at a first end 24a with respect to a first pivot axis 21 directly on the lid carrier 12. The coupling is formed in the region of a front end 22 of the lid carrier 12. Next has the first one

Release lever 20, a first slider 23 which is slidably guided in a first link 23a along the opening direction 4 (see Figure 4).

Further, the first deployment lever 20 is pivotally mounted at a second end 24 b opposite the first end 24 a with respect to a second pivot axis 26 on a front carriage 25, which in the guide rail 10

slidably guided.

The first gate 23a has a course in which

Closed position, a distance to the lid support 12 initially remains the same, then decreases and finally again remains substantially the same. The first scenery 23a is, as far as possible also the others to be described

Scenes, suggested as a slide track, being omitted for reasons of clarity on the structural design of the scenes in the figures as far as possible. The scenes are here and below typically to a two-sided forced operation of a coupling element, such as glides or the like, with a one-sided leadership can be meant. The distance between the first link 23a and the lid carrier 12 is here and below related to a trajectory of the respective backdrop. The trajectories are to be understood schematically and give only limited

Information about an actual length respectively

Design of the scenes. In other words, that can

Coupling element be guided by contact with the backdrop from below, from above, from the side or combinations thereof.

On the front carriage 25 is pivotally mounted with respect to the second pivot axis 26, a locking lever 27 (see Figure 3). The second pivot axis 26 runs parallel to the Y direction. In the closed position, the locking lever 27 by means of a coupling element 28 in a corresponding, fixed second link 29 in engagement, the first movement of the first lever mechanism 14, such as the front carriage 25, in the X direction, initially locked (see Figure 4). Furthermore, in the locking lever 27 itself, a third link 30 is formed, with which the carriage 18 is coupled by means of a corresponding coupling element or in engagement. The third gate 30 is formed that when moving the carriage 18, starting from the

Closed position, first, a movement of the carriage 18 is released relative to the front carriage 25, and then the rear carriage 18 with the front

Carriage 25 cooperates (coupled) and this takes in the X direction to the rear.

By pressing the first lever mechanism 14 of the

Cover carrier 12 are issued at the front end 22. The second lever mechanism 15 comprises four levers 31 to 34. The first lever 31, which can also be referred to as a second deployment lever, is pivotably coupled via a hinge 35 with respect to a third pivot axis 36 directly to the cover carrier. Furthermore, the first lever 31 is pivotally coupled about a fourth pivot axis 31 a directly to the second lever 32. The second lever 32 is pivotally coupled directly to the third lever 33 with respect to a fifth pivot axis 32a, which in turn is pivotally coupled with respect to a sixth pivot axis 33a directly to the fourth lever 34. The fourth lever 34 is pivotally coupled relative to a seventh pivot axis 34a directly to the connecting element 17 and thus indirectly coupled to the carriage 18. In other words, it is a direct one, connected in series

Lever mechanism provided.

The first lever 31 and the second lever 32 are guided via a common, second slider 37 in a fourth link 38. Alternatively, only the first lever 31 or only the second lever 32 is coupled to the fourth link 38. The fourth gate 38 has a first portion 38a, which extends substantially parallel to the X direction, with a distance to the lid carrier 12 does not change in the closed position. The fourth gate 38 has a second section 38b which extends in a ramp shape, wherein the distance to the

 Cover carrier 12 is reduced. Subsequently, the fourth link 38 again runs substantially parallel to the X direction or enters an upper, first guide track 43 of FIG

Guide rail 10 via.

The third lever 33 has a first coupling element 39, which is guided in a second, lower guide track 40 of the guide rail 10 along the opening direction 4. Alternatively it is the first coupling element 39 is also guided in another guideway of the guide rail 10 or another backdrop parallel to the guide rail 10. By means of the first

Coupling element 39, the third lever 33 is slidably guided in the X direction, wherein the third lever 33 is simultaneously rotatable parallel to the Y direction. The first coupling element 39 is for example a pin, a rotary slide or

like. The third lever 33 is thus the first

Coupling element 39 pivotally, so that the couplings, such as joints, with the second and fourth levers 32 and 34 are pivotally about their position with respect to the Z-direction can change.

The third lever 33 additionally has a second one

Coupling element 41 which is engaged with a fifth link 42. The fifth backdrop 42, too

Locking link can be designated controls an orientation of the third lever 33. In the closed position

The locking link 42 locks the third lever with respect to the X direction. The course of the fifth link 42 is such that a distance to the lid carrier 12 in the

Closed position is initially increased and then remains substantially the same, approximately parallel to the guide rail 10 extends (see Figure 3).

The third and fourth levers 33 and 34 may also be referred to as a reduction mechanism or countershaft.

This counter gear translates a force applied by the carriage 18 so that a higher, necessary force for actuating the first and second levers 31, 32 for issuing the first cover 6 is provided. By operating the second lever mechanism 15, the lid carrier 12 and thus the lid 6 can be first issued at the rear end 22a. FIG. 4 shows a profile 45 of the cover trailing edge 8

shown this when moving the first cover. 6

starting from the closed position into the open position. It can be seen that the trailing edge 8 is first raised in the Z direction and then displaced parallel to the vehicle roof 2 via the second cover 7. The horizontal line in Figure 4 indicates the position in the fan position.

In a typical opening operation, in a first movement section, starting from the closed position described with reference to FIGS

 Drive slide device 13 by means of the drive

actuated. The drive moves the connecting element 17 in the X direction to the rear, wherein the locking of the

Lid carrier 12 is released. Next is about the

 Connecting element 17, the second lever mechanism 15 is actuated. By means of the fourth lever 34, the third lever 33 is tilted, so that the second and first levers 32, 31 are also actuated and a display of the first cover 6 in the Z-direction is achieved due to the corresponding, previously described scenes. Furthermore, this couples

Connecting element 17 with the carriage 18 and takes it to the rear. The coupling of the connecting element 17 with the carriage 18 can in a known per se, for example by means of a resilient locking block, the scenes guided engages in a recess on the carriage 18, so that a mechanical coupling is ensured. But there are also other solutions. In this first movement section, the cover 6 is moved into the fan position (see FIG. 5), wherein the carriage 18 or the drive slide device 13 is not yet coupled to the front slide 25, since the rear slide 18 is relatively movable due to the third slide 30

with respect to the first lever mechanism 14 is displaceable.

FIG. 6 shows the ventilation position in a side view.

In addition, the guide rail 10 is shown with the channels 40 and 43.

FIG. 7 shows the ventilation position from the inside. It can be seen in particular that the coupling element 41 of the third lever 33 through the fifth link 42 in the Z direction downwards

is controlled and then in the horizontal section of the

Guideway 40 can dip. Furthermore, it can be seen that the carriage 18 is still coupled in the horizontal section of the third slot 30 of the locking lever, that is to say relatively in the X direction with respect to the first lever mechanism 13

is displaceable.

FIG. 8 shows a perspective view of a further movement section of the opening process. In the further displacement of the drive slide device 13, the first and second lever mechanism 14 and 15 are pulled in the X direction to the rear and moved over the slider 23, 37 in the respective scenes ramp in the Z direction upwards, the first cover 6 is raised , In other words, the carriage 18 and the

 Drive slide device 13 now with the first

Lever mechanism 14 also coupled. The two sliders 23, 37, which are formed as a rotary glider, are tilted according to the slide tracks.

FIGS. 9 and 10 show a further state of the arrangement 11 in a further movement section. The first cover 6 is now moved further to the rear, this being moved over the second cover 7.

In a subsequent movement section, the first cover 6 is in the final open position on the second

Cover 7 moved (see, for example, analog representation of the second embodiment in Figure 17). In this case, the mechanics of the assembly 11, in particular the second

Lever mechanism 15 laterally on the second cover. 7

past.

The described embodiments of the first lever mechanism 14, the coupling of this to the drive slide unit 13, the locking of the first lever mechanism 14 in the X direction in the closed position and the coupling of

 Drive slide device 13 to the second lever mechanism 15 may also be configured differently. For example, it is conceivable that the connecting element 17 is not connected to the fourth lever 34, but the carriage 18 itself to the fourth lever 34. The locking means locking lever 27 may be different, such as a reverse link guide the second link 29th

In the described arrangement 11, it is essential that the second lever mechanism 15 is articulated centrally on the first cover 6 with respect to a length 44, at least in a range of 40% to 70% of the length 44, to the cover carrier 12 in the hinge 35 (see FIG. 4) ). The length 44 is in the X direction In other words, the articulation can also be related to the lid carrier 12. In other words, the hinge 35 is arranged with the third pivot axis 36 in the middle of the first lid 6.

This has the positive effect that the second lever mechanism 15 does not have to be guided over the full length of the second lid 7 in the X direction on the second cover 7. Accordingly, less space for the mechanics in the

 Vehicle roof 2 are provided. In other words, the vehicle roof 2 is less open to the rear in the opening direction 4. As a result, the second cover 7 can establish a transverse connection, that is to say in the Y direction, to the vehicle roof. Thereby, a rigidity of the vehicle can be increased, for example, forces are conducted in the transverse direction over the fixed roof element 7. Due to the special design of the second lever mechanism 15, the normally resulting lowering the

Lid trailing edge 8 through the first lever mechanism 14th

be compensated. Due to the configuration of the second lever mechanism 15, despite the compared to a

Coupling in the area of the trailing edge 8 lower

Abstützverhältnisses be provided a stable mechanism that allows the exhibition of the lid in the desired path. This support ratio would have when using a single, rear deployment lever instead of

another three levers 32 to 34 a large stroke result, which is compensated by the described arrangement 11. The support ratio is exemplary in Figure 17 for all

Embodiments shown as a trapezoid T. The first cover 6 is thus supported by a stable trapezoid. The support length 48 corresponds to about 50% of the length 44 of the lid 6. A free length 49 is the length of the second cover 7 for transverse attachment by the application according to

Arrangement is available. Figures 11 to 17 illustrate a further embodiment of the invention. Essentially, the above applies

Described analogously, so that the details are not repeated. In contrast to the first embodiment, the second lever mechanism 15 is constructed differently, as follows

is described.

FIG. 11 shows the arrangement 11 in the closed position.

Again, a curve 45 of the lid trailing edge 8th

shown, this takes place during the opening process.

The second lever mechanism 15 has in the second

 Embodiment only two levers, the first lever 31 and the second lever 32. The two levers 31, 32 are in

 Embodiment coupled to a control link 46 which controls a movement of the second lever mechanism 15. The

Control link 46 is formed in the locking lever 27, which is otherwise functionally configured as described above. The locking lever 27 has the third as above

Kulisse 30, about the carriage 18 with the

Arretierungshebel 27 is coupled. The second lever 32 is directly pivotally coupled to the carriage 18. Figure 11 also shows the Arretierungskulisse 29 (second

Gate 29) for the locking lever 27, which serves analogously to the top of the function of the lock in the X direction, but due to the arrangement on the other side of the front Slide 25 with respect to the X-direction, approximately in Figure 11 right of the second pivot axis 26 (not shown in Figure 11, see Figure 3 analog), a reversed first course portion has, such as from bottom to top. In Figure 15, the corresponding coupling element 47 of the locking lever 27 can be seen in perspective, which with the

Arretierungskulisse 29 is coupled.

Figure 12 shows in detail the locking lever 27 and the design of the scenes 46 and 30. In particular, the

 Control link 46 has a course with a first portion 46 a, in which the distance from the lid carrier 12 in the

Closing position increases, with a second portion 46 b, in which the distance is substantially the same, and a third portion 46 c, in which the distance decreases.

The first lever mechanism 14 is similar to the above constructed, in particular functional, with constructive differences are present, such as the design of the front

Schlitten's 25th

Analogously to the above, starting from the closed position during the opening process, force is applied to the drive slide device 13 by means of the drive. This unlocks it

Connecting the cover carrier 12 and the carriage 18 is then of the connecting element in the

Opening direction 4 taken to the rear. The first

Lever mechanism 14 and the front carriage 25 is in this first movement section with respect to the

Opening direction 4 locked.

By the coupling of the second lever 32 with the carriage 18, the first lever 31 and the second lever 32nd controlled according to the control link 46. In this case, the fourth pivot axis 31a is moved in the X direction. As shown in Figure 13, an intermediate state on the way to

Ventilation, is the fourth pivot axis 31a in the second portion 46b of the control link 46th

In Figures 14 and 15, the fan position is shown from the outside and inside. In this case, the first lever 31 is positioned approximately vertically. The two levers 31 and 32 are arranged so that the fourth pivot axis 31a is located in the third section 46c of the control link 46.

FIG. 16 shows a further movement section in FIG

Opening process. In this case, the first cover 6 is at least partially moved over the second cover.

In Figure 17, the full open position is shown. In this case, the entire trajectory 45 of the trailing edge 8 of the first lid 6 is shown. The first cover 6 protrudes with its trailing edge 8 almost to the trailing edge 8 ^{λ of} the second lid 7 with respect to the opening direction 4 zoom. Optionally, the first cover 6 arbitrarily or congruent to the second

Cover 7 are moved. Analogous to the above, the coupling of the first lever 31 with the lid carrier 12 is approximately in the middle, so that, as shown in Figure 17, the second lever mechanism 15 approximately centrally with respect to the second lid 7 in the open position

is arranged. This results in the above advantages.

Figures 18 to 23 illustrate a third embodiment. In essence, the previously described analog applies, so that the details are not repeated. In contrast to the first and second embodiments, the second lever mechanism 15 is in turn constructed differently. It should be noted that the second lever mechanism 15 almost

the same as that according to the second embodiment, but the control thereof is different upon issuance, as will be described below.

The control link 46 is not formed in the locking lever 27, but is stationary with respect to the

 Guide rail 10 is arranged, approximately in a separate

Setting component. The course of the control link 46 is formed similar to the top. The second lever mechanism 15 is thus not controlled by coupling with the locking lever 27 in the movement. This has the consequence that the lid trailing edge 8 of the first

Cover 6 can take a more homogeneous course,

In particular, the lid can be almost horizontally moved at a right angle by the Z-direction method, as indicated by the curve 45.

FIG. 19 shows the fan position after a first

Movement section starting from the closed position. The further figures 20 to 23 show further states of

 Arrangement 11 when opening the first lid 6 as already described above.

The third embodiment allows the above advantages and functions analog.

Common to all three embodiments described is that the cover coupling of the second lever mechanism 15 does not take place in the region of the rear end of the lid carrier 12, but preferred, approximately in the middle. The described embodiments of the drive slide device 13, the first lever mechanism 14 and the implementation of

Locks in the X direction are variable and can

alternatively be constructed differently. For example, corresponding scenes, such as the first link 23a, the second link 29 or the third link 30 have other courses, as far as the corresponding function is ensured. The gliders described may take various forms in the context of expert action, be designed as a rotary glider. Put the gliders

Coupling elements or engagement elements. The scenes described may be part of the guide rail 10 itself, but also part of separate sliding elements.
