Description

The invention relates to a door lock actuator for the electrical actuation of a door lock.

The not published at the time of application EP14192841.4 relates to a tactile device which can be considered as such a door lock actuator. The design requires and it is intended there that the local actuator, which the user operates to operate the door lock, is substantially spatially stationary, and the door lock operation is achieved substantially in one way.

In another context, namely a combination of electric window opener and mechanical door handle, concerns the DE 20 2009 010 746 U1 a vehicle door with a manually operable handle, which is swingable out of a rest position about at least one pivot axis, wherein at least a part of the handle has at least one other degree of freedom of movement, by moving at least the part of the handle according to the further degree of freedom of movement, the electric actuator of the window operable is. The door can only be opened mechanically here.

Starting from the first-mentioned sensing device, it was an object of the present invention to provide various possibilities of door lock operation, including at least one electrical, with only one door lock actuator. The object is solved by the independent claims. Advantageous developments are defined in the subclaims.

In particular, the object is achieved by a door lock actuator for a motor vehicle door, the door lock actuator having a first switch and a first axis of rotation of a first joint along a first degree of freedom, preferably with respect to the motor vehicle door or a further explained below in more detail actuator, pivotally mounted or storable first pivot arm, wherein the first pivot arm has a further degree of freedom substantially perpendicular to the first axis of rotation and the first switch is operable via a movement of the first pivot arm along a first direction of the further degree of freedom, wherein the first switch is provided via a signal line to be connected to an electric door lock, so that the electric door lock with the first switch is actuated. A further solution of the problem is the use of a door lock actuator in the motor vehicle door for actuating the door lock of the motor vehicle door by means of the switch.

The object is further achieved, in particular, by a motor vehicle door system with a motor vehicle door and with a door lock actuator according to the invention and with a door lock, the motor vehicle door system having a signal line which connects the first switch to the electric door lock, or by a motor vehicle having such a motor vehicle door system.

The object is further achieved in particular by a use of a door lock actuator according to the invention in a motor vehicle door system or motor vehicle, wherein the first switch is used for actuating an electric door lock.

As a result, a higher flexibility of the operation of the Türschlossbetätigers is achieved. On the one hand, a swivel arm is provided, which can be used directly or indirectly for the electrical or mechanical actuation of the door lock or which can be used for a more complex (eg in two different pivot states) actuation via a transmission, at the same time exists the electronic operation of the door lock means of the switch along the further degree of freedom.

A switch is preferably understood to mean an electromechanical arrangement which is set up to generate an electrical switching signal, which is known e.g. particularly preferred may be a microswitch. However, sensor-based switching arrangements with a sensor (e.g., Hall sensor) and an evaluation unit (e.g., microcontroller, comparator) are also conceivable. Actuation of the switch is preferably understood to mean bringing the switch from one switching state into the other switching state.

A movement of the first pivot arm along a direction of the further degree of freedom is preferably understood to mean a movement which has a movement component along this direction.

A signal line is preferably a line for transmitting a switching signal, be it physically wired or wireless. For example, the signal line is a cable or radio link.

For the purposes of this application, "substantially perpendicular" is ideally understood to mean a 90 ° angle, but a certain tolerance range of preferably less than ± 40 °, particularly preferably less than ± 20 °, very particularly preferably less than ± 5 °, is generally present be.

Upon actuation of the door lock, e.g. the opening / closing of the door latch and / or the locking / unlocking understood.

The use of the atomic number "first" in the independent claim is only due to the better distinguishability of the components with respect to components further mentioned later in preferred embodiments and does not imply that a further corresponding component must necessarily be present.

In a further embodiment of the present invention, the first pivot arm is acted upon (directly or indirectly) along at least a portion of the first degree of freedom by a first spring element.

As a result, the further degree of freedom is reduced at least for certain low acting on the pivot arm adjusting forces, so that only if a deliberate adjustment to take place along the further degree of freedom and a targeted force is applied to the pivot arm, the switch is actuated. Superfluous game can be avoided as well.

The spring element is for example a leaf spring, particularly preferably snap spring - the latter is particularly well suited because of its non-linear characteristic, since it has virtually no deformation up to a relatively high force, but then can be deformed abruptly and with less force. Thus, a very good threshold value for the actuation of the switch or the switch can be achieved, so that the first joint is not already "yawed" with small adjusting forces but not too heavy to be actuated (which is the case, for example, with a hard Hook's spring) would). The spring element is particularly preferably coupled to the first switch.

In a further exemplary embodiment of the present invention, the first joint has an axle element, which is displaceably guided in a slot.

As a result, the further degree of freedom is specifically defined in a direction transverse to the first axis of rotation of the first joint. The axle element is preferably arranged coaxially with the first axis of rotation. It is e.g. a pin or pin. In this case, the axle element can be guided directly (for example, by inserting a region of the shaft element directly into the oblong hole) or indirectly in the oblong hole (eg, by arranging the axle element on a holder or having another holding region, and this holder or the holding region is in the oblong hole) slidably guided). The axle is either rotatable in the slot. Alternatively, the axle element can be arranged rotationally fixed relative to the slot, and the first pivot arm is rotatably mounted on the axle.

In another embodiment of the present invention, the first hinge has a swing arm side part and a motor vehicle door side part, and the long hole is provided in the motor vehicle door side part.

As a result, an optimal rotational connection between the pivot arm and the axle element can be maintained, since the further degree of freedom is not defined with the same element which also produces the rotary connection (the axle element), but the degree of freedom is achieved by displacing the axle element itself. Under Schwenkarmseitenteil a schwenkarmseitiges hinge part is understood, under the vehicle door side part a motor vehicle door side hinge part. Schwenkarmseitenteil and motor vehicle door side part are preferably connected to each other by the axle.

In a further embodiment of the present invention, the axle element is displaceable on one side of the axle element in the oblong hole substantially perpendicular to the first axis of rotation, and preferably rotatable, guided (direct or indirect) and on another side of the axle element it is opposite to the first axis of rotation the further degree of freedom can not be displaced, and preferably in a preferably circular hole rotatably mounted.

As a result, a pivoting movement between the one side of the axle element and the slot along the other degree of freedom is achieved while on the other Side of the axle element a mainly on the degree of freedom of the first axis of rotation (or depending on the embodiment still further) limited connection exists. This is advantageous, for example, if the swivel arm serves directly as an actuating element, since then it does not depend on a parallel guidance of the entire first swivel arm along the further degree of freedom (the user does not need a parallel movement for actuating). In this case, it is more advantageous if the further degree of freedom exists only in a certain area, especially where the first switch is arranged. A certain tolerance range (since play is generally present) is included under "not displaceable with respect to the first axis of rotation", ie preferably the displaceability along the further degree of freedom is at least smaller, preferably by a factor of 0.1, particularly by a factor of 0.05, than that Displaceability of in the region of the slot.

In a further exemplary embodiment of the present invention, the axle element is displaceable on one side of the shaft element in the oblong hole substantially perpendicular to the first axis of rotation and preferably rotatably guided (directly or indirectly) and on another side of the axle element in a further slot substantially perpendicular to the first displaceable first rotary axis and preferably rotatably guided (directly or indirectly).

As a result, a parallel displacement of the first pivot arm along a direction of the further degree of freedom is advantageously given, which is particularly useful if you want to exploit the degree of freedom via a gearbox. The slots are preferably parallel to each other.

In a further embodiment of the present invention, the door lock actuator has a further switch and the further switch is operable via a movement of the first pivot arm in a second direction opposite to the first direction along the further degree of freedom.

As a result, two different switches can be actuated by two opposite movements along the further degree of freedom and can be used for the door lock actuation, eg in one direction open, in the opposite direction lock. Preferably, the swivel arm is acted upon (directly or indirectly) along at least one further subregion of the further degree of freedom by a second spring element, so that the first swivel arm is guided in one direction by the first and in the other direction is limited by the second spring element in its freedom of movement force-dependent.

In a further embodiment of the present invention, the door lock actuator has a stop which, in a pivot position of the first pivot arm, restricts movement of the first pivot arm more along the further degree of freedom than in another pivot position of the first pivot arm.

As a result, an actuation of the door lock is limited to a certain angular state range of the pivot arm. The degree of restriction is preferably such that actuation of the switch in the one pivot position of the first pivot arm is not possible. For example, a stopper is present, which blocks the further degree of freedom in a corresponding extent from a certain swung-out state (this can be used, for example, to prevent an operation when the user activates the swivel arm too much) and / or there is a stop, which blocked from a certain pivoted state, the further degree of freedom (this can be used, for example, to an operation by rewinding - for example, due to a return spring - to prevent the swing arm). The stopper is preferably a nose, which e.g. is arranged on the pivot arm and pushes at a certain angular position in a gap in the slot.

In a further embodiment of the present invention, the first switch is stationary with respect to the first pivot arm.

As a result, an actuation via a transmission can be implemented particularly advantageously. As a result of the stationary arrangement, the switch rotates with the swivel arm and the direction of movement which actuates the switch is thus constant relative to the swivel arm and, to that extent, independent of the angle of rotation of the swivel arm. Preferably, in the presence of a second switch and the second switch is stationary with respect to the first pivot arm.

In a further embodiment of the present invention, the first pivot arm on a manually to be pulled or manually pressed operating portion and thus is also an actuator.

As a result, a simple construction is provided, by means of which two different types of operation are possible - by pulling or pushing the first pivot arm, so that a movement along the first degree of freedom follows (which is guided for example via a Bowden cable to the door lock), and by pressing (or pulling ) of the pivot arm in the region of the first joint, so that a movement along a direction of the further degree of freedom actuates the switch.

• und das Betätigungselement ist über das zweite Gelenk an dem ersten Schwenkarm gelagert,
  oder
• das Betätigungselement ist über das erste Gelenk an dem ersten Schwenkarm gelagert und somit liegt die Schwenkbarkeit des ersten Schwenkarms entlang des ersten Freiheitsgrads um die erste Drehachse gegenüber dem Betätigungselement vor, und der erste Schwenkarm ist über das zweite Gelenk an der Kraftfahrzeugtür, mittelbar oder unmittelbar, gelagert oder lagerbar.

In a further embodiment of the present invention, the door lock actuator has an actuating element with a manually engageable or manually to be pressed operating portion and it has a second joint,

• and the actuating element is mounted on the first pivot arm via the second joint,
  or
• the actuating element is mounted on the first pivot arm via the first hinge, and thus the pivotability of the first pivot arm is along the first degree of freedom about the first axis of rotation relative to the actuator, and the first pivot arm is directly or indirectly connected to the motor vehicle door via the second pivot; stored or storable.

As a result, a more complex in construction, but more appealing for the user type of operation can be realized. The second joint is preferably a hinge. It preferably has an axis of rotation which is substantially parallel to the first axis of rotation.

In a further embodiment of the present invention, the door lock actuator has a second pivot arm, which is pivotally mounted or storable via a third joint relative to the motor vehicle door, and the actuating element is mounted on the second pivot arm via a fourth joint.

As a result, the actuating element is displaced parallel. The third and fourth joints are preferably hinges. Their axes of rotation are preferably parallel to the first axis of rotation. The four joints preferably form a four-bar linkage or parallelogram gearbox. In this case, the axes of the first and third articulation are preferably stationary relative to the vehicle door.

In a further exemplary embodiment of the present invention, the first pivoting arm is preferably bidirectionally displaceable along the further degree of freedom by means of a rotational movement of the actuating element taking place about the fourth joint.

As a result, the fourth pivot serves as a fixed point about which the actuating element is pivotable, so that the first pivot arm can be moved along the further degree of freedom by pressing or pulling the actuating element. For this purpose, the fourth rotary joint is preferably at least temporarily stationary in its position relative to the door.

In a further embodiment of the present invention, the actuating element has at least one actuating surface on both sides of the fourth joint.

As a result, a rotation about the fourth pivot joint in one or the other direction (depending on which actuating surface is pressed) can be achieved solely by a type of actuating surface (pressure surface or traction surface). The first pivot arm can thus be displaced in two opposite directions with one actuation (pushing or pulling) along the further degree of freedom, and thus two different switches (the first switch and the further switch) can be actuated. Preferably, the actuating surfaces on both sides of the fourth joint pressure surfaces, preferably exclusively pressure surfaces. This is e.g. very advantageous if the actuator is flush with the vehicle door surface and only a push should be possible.

In a further embodiment of the present invention, the actuating element is exchangeable by means of an actuator between two positions, preferably via a parallel displacement.

As a result, two different operating situations are provided to the user. In this case, the actuating element is preferably interchangeable along the first degree of freedom of the first pivot arm between the two positions. Preferably, the one position is a retracted into the motor vehicle door position of the actuating element. Preferably, the outer surface (visible surface) of the actuating element terminates flush with the surface (visible surface) of the motor vehicle door. Preferably, the other position is a position protruding from the vehicle door and preferred is provided in this protruding position at least one traction surface for the user to operate the door lock actuator and / or as an attack surface for swinging the vehicle door. Particularly preferably, in the protruding position, a rear wall of the actuating element facing the user terminates flush with the surface of the motor vehicle door. The actuator is for example an electromechanical actuator, which is coupled to one of the pivot arms or the actuating element, particularly preferably to the second pivot arm.

In a further embodiment of the present invention, the further degree of freedom of the first pivot arm in both of these positions, preferably bidirectional, is present and preferably usable by the user.

In this way, the switch can be actuated in both positions via a movement of the first pivot arm along the further degree of freedom.

In a further exemplary embodiment of the present invention, the actuating element has only pressure surfaces in one of these positions, and preferably at least one tension surface in the other position.

As a result, the actuating element is very flat in its design of the outer surface, at least in one position (since there are no tension surfaces), so that it presents itself to the user as a substantially smooth surface. This is particularly appealing when the actuator is in a retracted position in the vehicle door.

In another embodiment of the present invention, the operating member has a handle portion which is located in one of these positions within the vehicle door or is adapted to lie there and which in the other of these positions protrudes from the vehicle door and is manually engageable or adapted to protrude accordingly and to be tangible.

As a result, one of the conventional use (door handle) corresponding actuation opportunity is created, but at the same time reaches a windschnittigerer or visually appealing other state of a door lock actuator with only one component. Preferably, in the position projecting from the motor vehicle door, a rear wall of the handle section facing the user is aligned flush with the motor vehicle door surface.

In a further embodiment of the present invention, the door lock actuator or the motor vehicle door or a motor vehicle, in which the door lock actuator is or is installed, a control unit, by means of which the first switch is associated with a function when the actuator is in one of these positions and by means of which the first switch is associated with a different function when the actuator is in the other of these positions.

As a result, a plurality of functions can be linked to the switch. That that two different actions or action groups can be carried out with just one switch. For example, In one position (e.g., retracted position of the actuator), actuation of the switch is associated with unlocking the door lock and simultaneously activating the actuator to extend the actuator to a position protruding from the vehicle door. In the other position (e.g., the above position), the operation of the switch is then e.g. associated with an opening of the door lock, so that the vehicle door can be swung open. In this case, the further switch may be present, which e.g. in each position is linked to the same function.

In a further embodiment of the present invention, by means of the control unit, the further switch is associated with a function when the actuating element is in one of these positions, and the further switch is linked with a different function by means of the control unit when the actuating element is in the other located in these positions.

As a result, a plurality of functions can also be linked to the further switch. That that with two switches e.g. four different actions or action groups are feasible.

In a further embodiment of the present invention, the door lock actuator in addition to the first switch on a mechanical door lock actuator or a coupling portion for a mechanical actuating means of the door lock on.

As a result, an additional possibility of door opening is given, so that the probability of failure of the door lock actuator (eg in an accident) is reduced.

This possibility alone is a very advantageous aspect of the invention, which is also detached from the embodiment with a pivoting arm and the first joint, e.g. in a separate application, e.g. as Türschlossbetätiger, which has a manual actuator, by means of which the first switch is actuated, wherein the first switch is intended to be connected via a signal line with an electric door lock or connected, so that the electric door lock with the first switch is actuated wherein the door lock actuator in addition to the first switch has a mechanical door lock actuator or a coupling portion for a mechanical actuation means of the door lock, optionally in combination with in particular the following preferred features.

A mechanical door lock actuator has e.g. a transmission (e.g., a traction mechanism / hydraulic transmission / cam mechanism / rod transmission, etc.) which is connected or connectable to the door lock. A mechanical actuator is preferably a part of such a transmission, e.g. a Bowden cable. Mechanical means here preferably that the device or the actuating means is operable without electrical current / voltage and therefore particularly suitable as an emergency system.

The coupling section is preferably a section which preferably differs from other sections of the door lock actuator in that it provides for a form-locking fastening possibility for the actuating means, e.g. a recess for a nipple of a Bowden cable.

The mechanical door lock operating device or the mechanical actuating means of the door lock coupled to the coupling section can preferably be actuated by the user by means of an emergency operation, and thus the door lock can be actuated mechanically by means of the emergency operation. Under an emergency operation is preferably understood an operation that the user can perform only after unlocking the Notbetätigungsmöglichkeit. Unlocking may be, for example, one or more actions that require a direction of movement other than the operation of the emergency operation (eg, unfolding a cover or pulling out a safety pin) and / or one or more actions that require overcoming a resistance maximum (eg breaking up a predetermined breaking point, the release of a, preferably reversible, latch or clip holder or other latching, eg latching by means of a spring-biased ball in a Kontormulde).

Preferably, the emergency operation with the actuator is feasible. For example, For example, the actuator is normally restricted to a particular regular operating range (e.g., by a stop located above a predetermined breaking point or latch). For emergency operation, the actuator is then unlockable by means of an increased force (e.g., by breaking the break point or disengaging the latch) so that it is movable in an extended actuation area, the door lock being mechanically actuable by movement of the actuation element in the extended actuation area. This can e.g. be designed so that a part of the actuator or this as a whole "can be torn out" and then the lock can be operated by a cable, Bowden cable or an operating rod in an emergency.

Preferably, a predetermined breaking point is characterized in that the predetermined breaking point is releasable by applying a force exerted by a human effort, i. without additional power supply. Particularly preferably, the predetermined breaking point has a material thickness which is at least partially smaller than other regions.

FIGS. 1a, 1b The Türschlossbetätiger 1 has a first switch 10 and one about a first axis of rotation 21.1 of a first joint 21 along a first degree of freedom 31 here opposite the motor vehicle door 100 pivotally mounted or storable first pivot arm 30. The first pivot arm 30 has a further degree of freedom 32 perpendicular to the first axis of rotation 21.1. The first switch 10 can be actuated via a movement of the first pivot arm 30 along a first direction of the further degree of freedom 32. The first switch 10 is intended to be connected via a signal line 110 with an electric door lock 120, so that the electric door lock 120 with the first switch 10 is actuated. Furthermore, these figures also show the motor vehicle door system with motor vehicle door 100, the door lock actuator 1 and the door lock 120, wherein the motor vehicle door 100 has the signal line 110, which connects the first switch 10 with the electric door lock 120.

In Fig. 1 a, the unactuated state of the door lock actuator 1 is shown. Fig. 1b shows the actuated state, which starting from Fig. 1 a is achieved by moving the first pivot arm 30 to the right along the further degree of freedom 32.

Furthermore, here a preferred embodiment of the further degree of freedom 32 is shown by means of a slot bearing. For this purpose, the first joint 20 on an axle 21.2, which is slidably guided in a slot 21.3.

FIGS. 2a -e show based on Fig. 1 a and 1b different views of a preferred embodiment of a door lock actuator 1 according to the invention, which is designed here by way of example as a door inner handle, but can also be configured as an outside door handle. Fig. 2a shows a section through a front view, Fig. 2b a perspective view of obliquely left front / top, wherein the first pivot arm is shown only in sections, Fig. 2c a perspective detail view of the upper portion of the first joint 21 obliquely from the left front, slightly from above, Fig. 2d a further perspective detail view of the upper portion of the first joint 21 obliquely from the right front / top, Fig. 2e another perspective detail view of the upper portion of the first joint 21 from behind. While Fig. 2a, 2b, 2c and 2e show the door lock actuator 1 in a state in which the first switch 10 is not operated, shows Fig. 2d a state in which the first switch 10 is operated.

The first pivot arm 30 is acted upon along at least a portion of the first degree of freedom 31 by a first spring element 11. The spring element 11 is here a preferred snap spring and coupled to the first switch 10. The first joint 21 has a swing arm side part and a motor vehicle door side part and the slot 21.3 is provided in the vehicle door side member. The axle 21.2 is a pin which is guided on one side in the slot 21.3 perpendicular to the first axis of rotation 21.1 slidably. On another side of the axle 21.2 of the pin is not slidably mounted in a hole 21.4 relative to the first axis of rotation 21.1. The pin is rotatably mounted and the first pivot arm 30 is rotatably mounted on the pin.

The door lock actuator 1 has two stops 50, 50 ', which restrict a movement of the first pivot arm 30 along the further degree of freedom 32 in a pivot position of the first pivot arm 30 more than in another pivot position of the first pivot arm 30 stop blocked 50 from a certain swung out State of the pivot arm 30 the further degree of freedom. Stop 50 'blocked from a certain pivoted state the other degree of freedom. The stops 50, 50 'are formed as lugs and arranged on the pivot arm 30. They slide at a certain angular position in a space between the axle 21.2 and a vehicle door side, fixed part in the slot 21.3, so that the axle 21.2 there can not be moved.

The first pivoting arm 30 has an actuating section to be pulled manually and manually to be pressed, and thus is at the same time an actuating element 60. The actuating element 60 has a pressure surface 61.1 as the actuating surface 61 in the region of the first joint 21 and a grip section 62 with tension surfaces 61.2 as the actuating surface 61 The door lock actuator 1 has, in addition to the first switch 10, a coupling section 33 for a mechanical actuating means, here for a Bowden cable, of the door lock 120. The actuator 60 is thus additionally connected or connected in a conventional manner via a Bowden cable with the door lock.

To actuate the door lock 120, the user can now either press on the pressure surface 61.1, whereby the axle 21.2 is moved within the slot 21.3 against the spring element 11 (in the in Fig. 2d shown position) and thus pivoted overall. As a result, the switch 10 is actuated. Due to the switch operation, the door lock 120 is then electrically operated. In addition, the user can pull the actuator 60 over the handle portion 62 and thus actuate the door lock 120 via the Bowden cable. In this embodiment, due to the redundant mechanical door opening possibility higher security (eg in an accident) before.

FIG. 2f shows a variant of an embodiment of the door lock actuator 1 according to Fig. 2a-e in which the axle 21.2 is slidably and rotatably guided in the slot 21.3 and is rotatably supported in the other hole on the other side. The first pivot arm 30 is rotatably or non-rotatably mounted on the axle 21.2 or he has the axle 21.2 as part of.

Fig. 3a . 3c and 3d show the door lock actuator 1 in a retracted position of the actuator 60 (see below) during Fig. 4a . 4b and 4c show an extended position. Fig. 3a is a plan view of the door lock actuator 1. Fig. 3b is a rear view of the first pivot arm 30 in the region of the first joint 21st Fig. 3c and 3d show the operation of the switch 10 ( Fig. 3c ) or the switch 40 ( Fig. 3d ) in the retracted position of the actuator 60 and Fig. 4b and 4c show the operation of the switch 10 ( Fig. 4b ) or the switch 40 ( Fig. 4c ) in the extended position of the actuator 60.

The door lock actuator 1 has a further switch 40 and the further switch 40 can be actuated via a movement of the first pivot arm 30 in a second direction opposite to the first direction along the further degree of freedom 32. The first pivot arm 30 is acted upon along a portion of the first degree of freedom 31 by a first spring element 11 and along a further portion of the first degree of freedom 31 by a further spring element 41 - both spring elements 11, 41 are here preferred snap springs and each with the respective switch 10, 40 coupled. Thus, the pivot arm 30 is limited in one direction by the first spring element 11 and in the other direction by the second spring element 40 in its freedom of movement force-dependent. The first switch 10 and the further switch 40 are stationary relative to the first pivot arm 30th

The axle 21.2 is a pin which rotatably guided on one side of the axle 21.2 in the slot 21.3 and perpendicular relative to the first axis of rotation 21.1 and on another side of the axle 21.2, unlike in the FIGS. 2a-e , Also rotatable in a further slot and guided relative to the first axis of rotation 21.1 slidably. The axle 21.2 itself is stationary relative to the motor vehicle door 100th

The door lock actuator 1 has a separate actuating element 60 with a manually to be taken and manually pressed operating portion. The actuating element 60 is mounted on the first pivot arm 30 via a second joint 22. The door lock actuator 1 has a second pivot arm 70, which is pivotally mounted or storable via a third joint 23 relative to the motor vehicle door 100. The actuating element 60 is mounted on the second pivot arm 70 via a fourth joint 24. The second, third and fourth joints are each pure rotary joints whose joint axes are substantially parallel to the first axis of rotation 21.1. The four joints 21, 22, 23, 24 form a four-bar linkage or parallelogram gear, wherein in each case the axes of the first and third joint 21, 23 are stationary relative to the vehicle door 100. The first pivot arm 30 is bidirectionally displaceable along the further degree of freedom 32 by means of a rotational movement of the actuating element 60 that takes place about the fourth joint 24.

The actuating element 60 has on both sides of the fourth joint 24 at least one actuating surface 61. The actuating surfaces 61 on both sides of the fourth articulation 24 are here pressure surfaces 61.1, 61.1 'and tension surfaces 61.2.

The actuator 60 is interchangeable by means of an actuator 80 between two positions via a parallel displacement. This is done by means of a rotation of the first pivot arm 30 along the first degree of freedom 31. The one position is a retracted into the motor vehicle door 100 position of the actuating element 60 (FIG. Fig. 3a . 3c, 3d ). In this case, the outer surface of the actuating element 60 is flush with the surface of the motor vehicle door 100. The other position is a position of the actuating element 60 protruding from the motor vehicle door 100 (FIG. Fig. 4a . 4b, 4c ). In this case, at least one traction surface 61.2 is provided for the user for actuating the door lock actuator 1 and / or pivoting the motor vehicle door 100.

The actuator 80 has here, for example, a transmission with a linearly movable plunger, which acts on the second pivot arm 70 against a restoring device 81 (eg spring) and thus causes a fixation of the fourth pivot joint 24 in the respective position, so that the actuator 60 advantageously to the axis of the fourth pivot joint 24 can be pivoted to achieve a displacement of the first pivot arm 30 along the further degree of freedom 32.

The actuating element 60 has only pressure surfaces 61.1 in the retracted position. The actuator 60 has a handle portion 62 which lies in one of these positions within the vehicle door 100 and which projects from the motor vehicle door 100 in the other of these positions and is manually engageable. In the protruding from the motor vehicle door 100 position, the rear wall of the handle portion is flush with the motor vehicle door surface.

The further degree of freedom 32 of the first pivot arm 30 is present in both positions in two opposite directions. As in Fig. 3c 1, the first switch 10 can be actuated by pressing on the pressure surface 61. 1 in the retracted position of the actuating element 60, as in FIG Fig. 3d can be actuated by pressing on the pressure surface 61.1 'in the retracted position of the actuating element 60 of the other switch 40 in the opposite direction. As in Fig. 4b shown, in the extended position of the actuator 60 still the first switch 10 can be actuated by pressing on the pressure surface 61.1 and, as in Fig. 4c shown, the other switch 40 can be actuated in the opposite direction by pulling on the traction surface 61.2.

In the Fig. 3a to 4c an embodiment is shown, in which the first joint 21, which has the further degree of freedom 32, the first pivot arm 30 relative to the vehicle door supports. Alternatively, however, another of the four joints may have the further degree of freedom 32, for example the joint 23, which may then be regarded as a "first" joint within the meaning of the claims, or analogously the joints 22 or 24. Depending on the case, then the here 70 designated pivot arm to be considered as the first pivot arm in the sense of the claims and the here designated 30 pivot arm as a second pivot arm.

Hereby, a new door lock actuator has been presented, which offers a wide variety of uses for the manner of door lock operation. This is special possible due to a joint which has two degrees of freedom and thereby at least one of these degrees of freedom, a switch is actuated, with which the door lock is actuated or actuated. The joint can be used directly as a storage for an actuator (eg door inner handle) or part of a complex transmission, in particular four-bar linkage, which allows a very comfortable and at the same time streamlined or protected (against dust / dirt / damage) positioning of an actuator. <B><u> REFERENCE LIST </ u></b> 1 Türschlossbetätiger 40 another switch 10 first switch 41 another spring element 11 first spring element 50 attack 21 first joint 60 actuator 21.1 Rotary axis of the first joint 61 actuating surface 21.2 axle 61.1 print area 21.3 Long hole 61.2 pull face 21.4 hole 62 handle portion 22 second joint 70 second swivel arm 23 third joint 80 actuator 24 fourth joint 81 Reset device 30 first swivel arm 100 Motor vehicle door 31 first degree of freedom 110 signal line 32 another degree of freedom 33 coupling section
