It can be used anywhere where it comes to attach in a relatively small space fasteners that can be opened as often as you want. These include, for example, computer cases, mobile phone shells, board attachments, base stations, cordless phones, panels and screens, also in the automotive sector. The connection of the fastener to the thin-walled component plays a key role. Thus, during frictional or ultrasonic welding, the connecting element has a material fit with a centering aid of the component. Prerequisite for this method is that fastener and component consist of the same or different welding compatible thermoplastics.

The locking element 30 which is a locking member 31 having a spherical shape, which is arranged on a mostly cylindrical bolt is, together with a transition element 33 as a ball stud 31 in this respect, it is a detachable connection by means of a ball stud in this invention 31 . 33 having locking element 30 for space-saving attachment of components.

The ball or the ball stud 31 . 33 with end-side ball thus forms a coupling that is already known as a simple principle of connectors. Such connectors ensure optimum fit while vibration isolation. This is within the clutch in a holding part 10 a ball socket, the following as a spout 40 (See all figures) is designated formed, in which the locking member 31 can snap. The spout 40 The connector is at the bottom of the respective holding parts 10 in the existing opening 11 mounted and held in a form-fitting manner. The ball stud 31 . 33 thus the locking element 30 , depending on the design of the component to be fastened 20 screwed, glued or clipped. The assembly of the component to be fastened 20 done by simply putting the ball 31 (Locking member) of the ball stud 31 . 33 (Locking element) and disassembly by removing the ball stud 31 . 33 ,

The viewer looks according to the cut AA in a plan view of the x / y plane, which lies within a vehicle not shown in detail parallel to a road surface.

The illustrated holding part 10 is designed as a vehicle-side body part and includes a non-visible from the outside holding part area 10.1 , the one opening 11 having. In the opening 11 is a spout 40 engaged, which has an inner contour, with the outer contour of the ball having locking member 31 matches.

In the component 20 , which with the holding part 10 can be reversibly brought into an assembly state, it is a lighting element.

Im in 1 shown partial section of the lighting element 20 is part of a translucent cover 21 and a part of the box-like structure of the lighting element 20 shown, wherein in the upper part of a junction V between housing structure 22 and cover 21 is shown.

To the case structure 22 belongs to a first structural area 22.1 over which the connection between housing structure 22 and cover 21 (compare junction V ) will be produced.

To the case structure 22 belongs a second structural area 22.2 structurally formed such that the latching element 30 ._; 30.1 with the second structural area 22.2 can be associated.

To the case structure 22 belongs to a third structural area 22.3 that with the second structure area 22.2 is in communication, the other body of the housing of the lighting element 20 forms.

The housing structure 22 comprises a fourth structural area 22.4 , the aperture or design panel within the installation space of the lighting element 20 is arranged.

The locking element 30 includes next to the locking member 31 for example, formed as a cylindrical bolt transition element 33 with the fastener 32 as screw outer thread 32 , wherein the transition element 33 an outdoor polygon 33.1 has, on which a tool attacks, by means of which a worker, the locking element 30 over the screw outer thread 32 in a prepared receiving channel 22:21 , in particular in a blind hole bore of the second structural area 22.2 screwed.

In the embodiment, the locking element 30 and the housing structure 22 made of plastic, so it's at the connection between locking element 30 and housing structure 22 is a plastic-plastic compound. It is envisaged that the worker to the assembly state between locking element 30 and housing structure 22 manufacture, from the outside with the appropriate tool, in particular an open-end wrench or a screw nut on the outer polygon 33.1 attacks to make the connection.

As a result, there is a problem that the lateral space of the outer polygon extending in the +/- y direction 33.1 must be kept free as an assembly room, so that the desired state of assembly can be generated. As a result, this mounting space is within the housing structure 22 disadvantageously not otherwise for components of the lighting element 20 to disposal.

In addition, the side of the outside polygon 33.1 , first seen next to the mounting room in -y-direction, the already mentioned first structural area 22.1 can be formed, which is the corresponding close to the holding part area 10.1 lying connection point V to the cover 21 manufactures.

In addition, the existing solution still has a disadvantage, which is that by the use of the external screw thread 32 as a fastener a relatively long blind hole 22:21 in the longitudinal direction (compare longitudinal axis X ) of the locking element 30 with an amount x2 that is between the top of the second structure area 22.1 , in particular the end face of the blind hole 22:21 and the bottom of the blind hole 22:21 is necessary to ensure appropriate stability between the second structural area 22.2 and the locking element 30 manufacture. In addition, also has the transition element 33 trained connecting web, the necessary for assembly external polygon 33.1 comprises, a relatively large length with a likewise in the longitudinal direction (cf. longitudinal axis X ) Amount x1_ on that between the holding part area 10.1 and the end face of the second structural area 22.1 , in particular the end face of the blind hole 22:21 is formed.

In other words, in the conventional solution, the inside of the housing structure 22 and outside the case structure 22 lying transition area Bx1_ with the amount x1_ (between holding section area 10.1 and the second structural area 22.2 ) and inside the case 22 lying attachment area Bx2_ (between the face and bottom of the blind hole 22:21 ) of the locking element 30 relatively long (x1 + x2), so that seen in the +/- x direction, a relatively large amount of space is needed to the desired connection between the lighting element 20 and holding part 10 by means of the conventional connection of the components 10 . 20 . 30 . 40 manufacture.

From the 1 is also clear that due to the arrangement described a space B within the lighting element 20 who in 1 is shown as dashed oval, is not available, since this space through the first and second structural area 22.1 . 22.2 the housing structure 22 is occupied.

However, it is desired that in particular the fourth structural region 22.4 , the bezel or the designer bezel opposite the presentation in 1 can be further guided in the -x direction and / or in the + y direction, the position of the opening 11 in the holding part area 10.1 should remain unchanged.

In accordance with the stated object, a solution is thus sought for this installation space, hereinafter referred to as "new" installation space B _N (see 2 ff.).

The invention consists in a first basic step therein, the second structural area 22.2 of the housing 22 to change so that the space requirement of the transition area Bx1_ and / or the attachment area Bx2_ is reduced, leaving the second structural area 22 continue in -x direction moves.

The invention consists in a second principal step therein, the second structural region 22.2 of the housing 22 to be changed such that by adjusting the space requirement of the transition area Bx1_und / or the attachment area Bx2_ also a shift of the second structural area 22.2 of the housing 22 in + y direction.

The invention discloses several embodiments that follow the principle of the invention, which will be explained below.

First embodiment:

The 2 according to the first embodiment also shows a section AA in the same x / y plane as in 1 ,

It is provided according to the first step according to the invention that on the holding part 10 releasably fastened component 20 by means of a locking element 30 ._; 30.2 , on the one hand as a locking member 31 with one end of the locking element 10 arranged ball is equipped in the holding part 10 ; 10.1 analogous to 1 releasably engages and with his the locking member 31 opposite end, which now in the embodiment of the first embodiment as a stepped footboard 34 is formed, placed in an injection mold and molded, so that the foot part 34 positively in a stepped receiving channel, in particular a stepped blind hole opening 22:22 of the second structural area 22.2 of the housing 22 injected.

The assembly is thus carried out in advance of the installation of the lighting element 20 by insert molding the foot part 34 , at the same time the housing structure 22 is formed so that the housing with the in the housing structure 22 , in particular in the second structural area 22.2 positively and integrally integrated locking element 30 ._; 30.2 (for attachment to the body-side holding part 10.1 ) is delivered.

Out 2 It becomes clear that the described prefabrication no longer requires a separate tool, whereby the transition region Bx12 with the length amount x12 compared to the prior art with the length amount x1_ the transition area Bx1_ shorter (Bx12 <Bx1) fails.

In addition, by the attachment of the locking element 30 ._; 30.2 within the second structure area 22.2 by means of extrusion coating a stable bond between the foot part 34 and blind hole opening 22:22 can be produced, compared to the in 1 shown solution requires a smaller depth, which also the attachment area BX22 with the length amount x22 compared to the prior art with the length amount x2_ of the attachment area Bx2_ shorter (Bx22 <Bx2) fails.

The result is thus the space requirement of the transition area Bx12 and the attachment areas BX22 reduced, leaving the second structural area 22.2 the housing structure 22 overall in -x direction wanders, causing the new space B _N with regard to the x Direction is created.

In addition, unlike the prior art, according to 1 no longer the need to keep free a mounting space for a tool seen laterally in the -y direction, since such a tool is no longer needed in this solution. This allows the first structure area 22.1 be formed in the second step such that starting from the connection point V essentially in the y-direction of a bridge 22:11 can be formed, which is longer in the + y-direction compared to the prior art. The longer jetty 22:11 thus extends into the area, which was occupied in the prior art by the provision of the mounting space, whereby (see 1 ) the structure of the second structural area 22.2 on his cover 21 facing side (left of the longitudinal axis X ) is essentially no longer needed, so that the desired new space B _N for the design panel 22.4 is created.

The possible over the prior art extension of the design panel 22.4 is in 2 shown by the cross hatching, whereby it is clear that only the bridge 22:11 an extension seen in the -x direction for extending the design bezel 22.4 , in -x direction represents.

The first step according to the invention has thus created the prerequisite, the desired space B _N by gradually shifting the structural parts in the -x direction and + y direction.

Second embodiment:

The 3 according to the second embodiment also shows a section AA in the same x / y plane as in the figures before.

It is provided according to the first step according to the invention that on the holding part 10 releasably fastened component 20 by means of a locking element 30 ._; 30.3 , on the one hand as a locking member 31 with one end of the locking element 10 arranged ball is equipped in the holding part 10 ; 10.1 analogous to 1 releasably engages and with his the locking member 31 opposite end, which now in the embodiment of the second embodiment as a fastener 32 a screw outer thread with end arranged screw head drive element 35 , In particular Torx drive is formed, so that the external screw thread 32 as a fastener form-fitting (as a plastic-plastic compound) in a receiving channel, in particular a through hole 22:23 of the second structural area 22.2 the housing structure 22 by means of the drive element 35 from the inside into the second structural area 22.2 can be screwed. Between the drive element 35 and the second structural area 22.2 the housing structure 22 is preferably a housing side crimp rib for sealing the interior of the lighting element 20 arranged.

The assembly does not take place in advance of the installation of the lighting element 20 but may before mounting the lighting element 20 on the holding part 10 ; 10.1 be made, with the cover 21 only after the assembly of locking element 30 ._; 30.3 and housing structure 22 he follows.

Out 3 It is clear that no separate tool is required by the described fastening, which from the outside of the lighting element 20 attacks, reducing the transition area Bx13 with the length amount x13 compared to the prior art with the length amount x1_ the transition area Bx1_ shorter (Bx13 <Bx1) fails.

In this embodiment, the attachment area BX23 with the length amount x23 not much shorter than the amount x2_ the conventional mounting area Bx2_ according to 1 because the plastic-plastic screw connection 32 as a fastening connection a certain length x2, x23 in the mounting area Bx2, Bx23 needed.

However, unlike the prior art 1 no longer the need, as seen in the -y direction to keep a mounting space for an externally attacking tool, since such an externally attacking tool in this solution is also no longer needed. This allows the first structure area 22.1 again be formed in the second step such that starting from the connection point V essentially in the y-direction of the bridge 22:11 is formed, which is longer than the prior art in the + y direction. The longer jetty 22:11 thus extends into the area, which was occupied in the prior art by the provision of the mounting space of the tool, whereby (see 1 ) the structure of the second structural area 22.2 on his cover 21 facing side (left of the longitudinal axis X ) is essentially no longer needed, so that the desired new space B _N for the design panel 22.4 is created. The possible over the prior art extension of the design panel 22.4 is in 3 again shown by the cross-hatching, it is clear that only the bridge 22:11 an extension seen in the -x direction for extending the design bezel 22.4 , in -x direction represents.

The first step according to the invention has thus created the prerequisite in this second embodiment, the desired space B _N by gradually shifting the structural parts in the -x direction and + y direction.

Third embodiment:

The 4 according to the third embodiment also shows a section AA in the same x / y plane as in the figures before.

It is provided according to the first step according to the invention that on the holding part 10 releasably fastened component 20 by means of a locking element 30 ._; 30.4 , on the one hand as a locking member 31 with one end of the locking element 10 arranged ball is equipped in the holding part 10 ; 10.1 analogous to 1 releasably engages and with his the locking member 31 opposite end, which now in the embodiment of the third embodiment as a cylinder pin 37 is formed, so that in turn designed as a foot cylinder pin 37 positive fit in a receiving channel, in particular a blind hole 22:24 of the second structural area 22.2 the housing structure 22 by means of a separate attachment member 36 which is a driving element 36.1 , in particular a Torx drive, from the inside into the second structural area 22.2 can be screwed.

The second structure area 22.2 and as a fastener 32 provided cylinder pin 37 have an opening into which the attachment member 36 as plastic-plastic Screwed is screwed, wherein the to the second structural area 22.2 directed surface of the drive element 36.1 a seal of the interior of the lighting element 20 towards the environment of the lighting element 20 causes.

The assembly does not take place here in advance of the installation of the lighting element 20 but may before mounting the lighting element 20 on the holding part 10 ; 10.1 be made, with the cover 21 only after the assembly of locking element 30 ._; 30.4 and housing structure 22 he follows.

Out 4 It is clear that no separate tool is required by the described fastening, which from the outside of the lighting element 20 attacks, reducing the transition area BX14 with the length amount x14 compared to the prior art with the length amount x1_ the transition area Bx1_ shorter (Bx14 <Bx1) fails.

In this embodiment, the attachment area Bx24 with the length amount x24 not much shorter than the amount x2_ the conventional mounting area Bx2_ according to 1 because the plastic-plastic screw connection 36 . 36.1 (see 4 ) by means of the attachment member 36 also a certain length x2 . x24 needed in the mounting area Bx2, Bx24.

However, unlike the prior art 1 no longer the need, as seen in -y-direction to keep a mounting space for an externally attacking tool, since such an externally attacking tool is no longer needed even in this solution. This allows the first structure area 22.1 again be formed in the second step according to the invention such that starting from the connection point V essentially in the y-direction of the bridge 22:11 can be formed, which is longer in the + y-direction compared to the prior art. The longer jetty 22:11 thus extends into the area, which was occupied in the prior art by the provision of the mounting space for the tool, whereby (see 1 ) the structure of the second structural area 22.2 on his cover 21 facing side (left of the longitudinal axis X ) is essentially no longer needed, so that the desired new space B _N for the design panel 22.4 is created. The possible over the prior art extension of the design panel 22.4 is in 4 again shown by the cross-hatching, it is clear that only the bridge 22:11 an extension seen in the -x direction for extending the design bezel 22.4 , in -x direction represents.

The first step according to the invention has thus created the prerequisite in this third embodiment, the desired space B _N by gradually shifting the structural parts in the -x direction and + y direction.

The latching element preferably comprises 30 in the region of the web-like transition element formed as a cylindrical bolt 33 a flange-like stop 33.2 (Stop flange), when screwing in the fastening member 36 for a positioning of the locking element 30 relative to the second structural area 22.2 provides. When assembling a pressing force on the locking element 30 from the outside in the direction of the housing structure 22 in the direction of the arrow according to the arrow P4 exercised, so that to the second structural area 22.2 directed bearing area of the flange stop 33.2 on the front of the blind hole 22:24 of the second structural area 22.2 positionally true. Through the flange-like stop 33.2 be the appropriate accuracy and a straight seat of the fastener 36 guaranteed. It is understood that in general also the bottom-side surface of the locking element 30 , hence the cylinder bolt 37 as a stop for the position of the locking element 30 relative to the second structural area 22.2 can serve, so that the flange-like stop 33.2 if necessary, can also be omitted.

The following embodiments are based essentially on the basic idea according to the first embodiment, but the method for assembling the latching element 30 has been changed, as will be explained below.

Fourth embodiment:

The 5 according to the fourth embodiment also shows a section AA in the same x / y plane as in the figures before.

It is provided according to the first step according to the invention that on the holding part 10 releasably fastened component 20 by means of a locking element 30 ._; 30.5 , on the one hand as a locking member 31 with one end of the locking element 10 arranged ball is equipped in the holding part 10 ; 10.1 analogous to 1 releasably engages and with his the locking member 31 opposite end, which now in the embodiment of the fourth embodiment as a cylinder pin 36 is formed, so that the cylinder pin is positively and as explained below, cohesively in a receiving channel, in particular a blind hole 22:25 of the second structural area 22.2 the housing structure 22 is attached.

The assembly takes place in the fourth embodiment, thus in advance of the assembly of the lighting element 20 by making a friction-welded connection between a turn as a foot part 37.1 trained cylinder pin (compare 5 ) and the housing structure 22 , where the cylinder bolt 37.1 especially in the second structural area 22.2 the housing structure 22 is integrally formed and integrally integrated, so that the housing structure 22 of the lighting element 20 a positive and integral locking element integrated 30 ._; 30.5 having, for attachment to the body-side holding part 10.1 serves.

The form fit is due to the corresponding contours between the foot part 37.1 formed in the fourth embodiment cylindrical bolt (outer contour) and the cylindrical blind hole 22:25 (Inner contour) guaranteed.

The material is closed according to the invention by producing a friction-welded connection.

In other words, the locking element 30 ._; 30.5 is formed as a friction welding element as follows.

The locking element 30 ._; 30.5 is preferably formed entirely of plastic and comprises at least one Reibschweißansatzelement 30.1 ,

Alternatively, a body of the locking element 30 ._; 30.5 formed of a metal and at least the area of the receiving channel, in particular the blind hole 22:25 of the second structural area 22.2 the housing structure 22 is connected, is as Reibschweißmantel or as Reibschweißmantel with a arranged on the Reibschweißmantel Reibschweißansatzelement 30.1 educated.

The body of the locking element 30 ._; 30.5 completely or partially surrounding Reibschweißmantel or Reibschweißmantel with arranged Reibschweißansatzelement 30.1 is also made of a plastic.

The locking element 30 ._; 30.5 with the friction welding attachment element 30.1 or the friction welding jacket or the friction welding jacket and the friction welding attachment element 30.1 are made of a rigid and stable plastic, such as thermoplastics with or without reinforcing fibers, such as polypropylene (PPF), polyamide (PA) and PA 6.6 GF 30 ; Polycarbonate and polyblends, such as PC / ABS, PC + ABS, PC + ABS / PC, ABS + ABS / PC.

In coordination with the material of the locking element made entirely of plastic 30 ._; 30.5 or the Reibschweißmantels or Reibschweißansatzelementes 30.1 consists of the housing structure 22 from a similar stable or the same plastic material. It is also possible that the case structure 22 made of a thermoset, while the locking element 30 ._; 30.5 or the friction welding jacket 30 or the friction welding attachment element 30.1 is constructed of a thermoplastic.

During the friction welding process, the friction welding attachment element 30.1 or the Reibschweißmantel and Reibschweißansatzelement 30.1 preferably a Polymerverkrallung to the housing structure 22 forth, so that in addition to the positive connection a reliable cohesive connection is achieved.

By means of a drive means, not shown, which is formed in one of the previously described embodiments as Reibschweißelement locking element 30 ._; 30.5 by means of relative movement, preferably by rotating the friction-welding element about its longitudinal axis X and moving the rotating Reibschweißelements in the axial direction, in the receiving channel 22:25 moved in the housing, so that a cohesive Reibschweißverbindung between the locking element 30 ._; 30.5 as Reibschweißelement and the housing structure 22 , in particular the second structural area 22.2 the housing structure 22 , arises.

The said relative movement between the housing structure 22 and latching element 30 ._; 30.5 is in addition to a rotation of the Reibschweißelementes also via a torsional vibration, so a taking place over a limited angle of rotation reciprocation of Reibschweißelementes in the receiving channel 22:25 the housing structure 22 or exclusively via an axial oscillation, that is, an axial reciprocating movement along the longitudinal axis X the locking element 30 ._; 30.5 within the recording channel 22:25 of the housing 22 achievable.

Especially when using very small amplitudes in torsional vibrations and / or axial vibrations Reibschweißelemente are also fastened, which are not themselves rotationally symmetric and / or are arranged in non-rotationally symmetrical receiving channels.

A further alternative consists in the combination of the above relative movements or a selection of the relative movements, so that a relative orbital oscillation is present. This procedure is already in the publication WO 2014/124841 described above, but is the locking element according to the invention 30 ._; 30.5 formed in a different manner and the use of the method differs from the known use, as will be clarified by the following description.

The inventors use only the known basic idea, which is to use the friction welding, in which by a relative movement between two components to be fastened together material-melting heat is generated by friction in abutting surface areas.

Out 5 It is clear that by the prefabrication described, that is, by making a friction-welded connection between a turn as a foot 37.1 trained cylinder pin (compare 5 ) and the housing structure 22 , in particular the second structural area 22.2 the housing structure 22 no separate tool is needed anymore, reducing the transition area BX15 with the length amount x15 compared to the prior art with the length amount x1_ of the transition area Bx1_ shorter (Bx15 <Bx1) fails.

In addition, by the attachment of the locking element 30 ._; 30.5 within the second structure area 22.2 by means of friction welding a stable bond between the cylinder pin 37.1 and blind hole drilling 22:25 can be produced, compared to the in 1 shown solution requires a smaller depth, which also the attachment area BX25 with the length amount x25 compared to the prior art with the length amount x2_ of mounting area Bx2_ shorter (Bx22 <Bx2) fails.

The result is thus the space requirement of the transition area Bx1_ and the attachment area Bx2_ reduced, leaving the second structural area 22.2 of the housing 22 overall in -x direction wanders, causing the new space B _N is created with respect to the x-direction.

In addition, unlike in the prior art according to 1 no longer the need to keep clear a mounting space for a tool laterally in -y direction, since such a tool is no longer needed in this solution. This allows the first structure area 22.1 be formed in the second step such that starting from the connection point V essentially in the y-direction of a bridge 22:11 can be formed, which is longer in the + y-direction compared to the prior art. The longer jetty 22:11 thus extends into the area, which was occupied in the prior art by the provision of the mounting space, whereby (see 1 ) the structure of the second structural area 22.2 on his cover 21 facing side (left of the longitudinal axis X ) is essentially no longer needed, so that the desired new space B _N for the design panel 22.4 is created. The possible over the prior art extension of the design panel 22.4 is in 5 shown by the cross hatching, whereby it is clear that only the bridge 22:11 an extension seen in the -x direction for extending the design bezel 22.4 , in -x direction represents.

The first step according to the invention has thus again created the prerequisite, the desired space B _N by gradually shifting the structural parts in the -x direction and + y direction.

The friction weld in the fifth embodiment specifically designed in various embodiments can be formed, wherein a first embodiment in 5 is shown.

The locking element 30 ._; 30.5 is made entirely of plastic and includes Reibschweißansatzelemente 30.1 in rib shape, on the underside of a web-like formed as a cylindrical pin transition element 33 flange stop 33.2 (Stop flange) are arranged.

The bottom side of the cylindrical as a foot part 37.1 trained bolt and thus the locking element 30 ._; 30.5 makes in the blind hole 22:25 a depth stop, so that the position of the cylindrical bolt 37.1 within the housing structure 22 is fixed.

In the described friction welding is formed by the relative movement at least between the Reibschweißansatzelement 30.1 and the housing structure 22 thus the inner wall of the blind hole 22:25 the material-melting heat, wherein the movement of the locking element 30 ._; 30.5 preferably as an axial oscillation, ie an axial reciprocating movement in the direction of the directional arrow P5 along the longitudinal axis X the locking element 30 ._; 30.5 within the recording channel 22:25 of the housing 22 he follows. As a result, the form-fitting and a reliable cohesive connection at least between the stop flange 33.2 the locking element 30 ._; 30.5 and the housing structure 22.2 achieved.

In the second embodiment, not shown, of the fifth embodiment, the locking element 30 ._; 30.5 also completely formed of plastic and includes Reibschweißansatzelemente 30.1 preferably in rib shape, which on the bottom side of the cylindrical foot part 37.1 trained bolt is arranged.

The formed in the region of the web-like cylindrical bolt transition element 33 arranged flange stop 33.2 (Stop flange) is then used exclusively for the positioning of the locking element 30.5 , therefore he points no friction welding attachment elements 30.1 on. In this embodiment, as a relative movement between the housing structure 22 and latching element 30 ._; 30.5 an over a limited angle of rotation taking place reciprocating movement of the locking element 30 ._; 30.5 in the direction of the directional arrow P5 along the longitudinal axis X in the receiving channel 22:25 of the housing 22 intended. As a result, the positive and a reliable cohesive connection at least between the bottom of the cylindrical, as a foot part 37.1 trained bolt and the bottom of the blind hole 22:25 the housing structure 22 achieved.

It is understood that the arrangement of the flange stop 33.2 is optional.

In a third embodiment, also not shown is without flange-like stop 33.2 only the bottom side of the cylindrical foot part 37.1 trained stud 37.1 and thus the locking element 30 ._; 30.5 in the blind hole 22:25 formed as a depth stop, so that the position of the cylindrical bolt 37.1 within the housing structure 22 is determined as a function of the material melting by the friction-welded connection. The friction welding attachment elements 30.1 are then preferably in rib shape, also on the bottom side of the cylindrical bolt 37.1 arranged and melt during the production of the friction-welded connection, so that the locking element 30 ._; 30.5 finally as a positive and a reliable cohesive connection at least between the bottom of the cylindrical bolt 37.1 and the reason of the blind hole drilling 22:25 the housing structure 22 comes in his desired position. In this third embodiment, the stop plane = the friction welding plane at the bottom of the cylindrical bolt 37.1 and the reason of the blind hole drilling 22:25 the housing structure 22 ,

In the first and second embodiment variant, the stop plane and the friction welding plane fall apart in contrast to the third embodiment variant.

Fifth embodiment:

The 6 according to the fifth embodiment also shows a section AA in the same x / y plane as in the figures before.

The previous explanations of the fourth embodiment apply analogously to the fifth embodiment, wherein the same reference numerals have been used for the same components.

One difference is that the positive locking by the corresponding contours between the formed as a foot part in the fifth embodiment (see 6 ) now conical as a foot part 37.2 trained cylinder pin (outer contour) and the now conical blind hole 22:26 (Inner contour) is guaranteed. As a result, the differently formed in the foot part locking element 30 ._; 30.6 in the blind hole 22:26 be introduced under preparation of a friction-welded joint, wherein preferably in a preferred embodiment in this embodiment, at least one Reibschweißansatzelement 30.1 , relative to the longitudinal axis X , on the radial lateral surface of the cylinder bolt 37.2 is arranged as in 6 is indicated.

In this embodiment, in turn, is proposed as a relative movement between the housing structure 22 and the locking element 30 ._; 30.6 an over a limited angle of rotation taking place reciprocating movement of the locking element 30 ._; 30.6 in the direction of the directional arrow P6 along the longitudinal axis X in the receiving channel 22:25 the housing structure 22 provided. As a result, the positive and a reliable cohesive conical circumferential weld joint at least between the lateral surface of the conical as the foot part 37.2 trained cylinder pin and the latching element 30 ._; 30.6 facing inner surface of the conical blind hole 22:26 the housing structure 22 achieved. In this embodiment, the stop plane and the so-called v-shaped friction welding plane fall apart.

Sixth embodiment:

The 7 according to the sixth embodiment also shows a section AA in the same x / y plane as in the figures before.

The 7 shows in another embodiment, another solution, which is essentially the 5 (fourth embodiment) and the associated description with the difference that corresponds to the locking element 30 ._; 30.7 at one of the ball 31 opposite end face of the cylindrical foot part 37.1 trained stud 37.1 a flange-like stop 33.2 (Stop flange), which is for a positioning of the locking element 30 ._; 30.7 relative to the second structural area 22 .2sorgt.

The trained as web-like cylindrical bolt transition element 33 and that as a cylindrical bolt 37.1 in the attachment area BX27 trained foot part thus go cylindrically steplessly into each other. Also, in the case structure 22 no blind hole 22:25 (see 5 ), but a through hole 22:27 educated.

When assembling a pressing force on the locking element 30 ._; 30.7 in the direction of the housing structure 22 according to the directional arrow P7 exercised, so that to the second structural area 22.2 directed bearing area of the flange stop 33.2 on the bottom of the housing structure 22 at the through hole 22:27 of the second structural area 22.2 the housing structure 22 positionally true.

The locking element 30 ._; 30.7 For example, in this embodiment, it is entirely made of plastic and includes friction-welding attachment elements 30.1 in rib form, which in this embodiment now on top of the flange stop 33.2 (Stop flange) are arranged.

In this sixth embodiment, by means of the flange-like stop 33.2 at the front of the cylindrical bolt 37.1 is arranged, the depth stop of the locking element 30 ._; 30.7 opposite the housing structure 22 educated. In addition, the position of the cylindrical bolt 37.1 within the housing structure 22 determined as a function of the material melting by the friction-welded connection, since at least one Reibschweißansatzelement 30.1 in rib shape now on the top of the flange stop 33.2 (Stop flange) is arranged.

The friction welding attachment elements 30.1 , preferably in the rib shape of the cylindrical bolt 37.1 melt during the production of the friction-welded connection, so that the locking element 30 ._; 30.7 finally, as a form-fitting and a reliable cohesive connection at least on the underside of the housing structure 22 comes in his desired position. In this sixth embodiment, the stopper plane = the frictional welding plane on the underside of the housing structure 22 in the plane between housing structure 22 and the top of the flange stop 33.2 (Stop flange).

The trained as a cylindrical bolt transition element 33 and that as a conical cylinder pin in the mounting area Bx28 trained foot part 37.2 go continuously into each other, the transition element 33 cylindrical and the foot part 37.2 is conical. Also, in the case structure 22 no conical blind hole 22:26 (see 6 ), but a conical through hole 22:28 educated.

When assembling a pressing force on the locking element 30 ._; 30.8 in the direction of the housing structure 22 according to the directional arrow P8 exercised, so that to the second structural area 22.2 directed bearing area of the flange stop 33.2 on the bottom of the housing structure 22 at the through hole 22:28 of the second structural area 22.2 the housing structure 22 positionally true.

The positive connection is in this seventh embodiment analogous to the fifth embodiment by the corresponding contours between the foot as part 37.2 formed conical pin (outer contour) and the now conical through hole 22:28 (Inner contour) guaranteed. This can do this in the foot section 37.2 differently formed locking element 30 ._; 30.8 into the through hole 22:28 be introduced under preparation of a friction-welded joint, wherein preferably in a preferred embodiment in this embodiment, at least one Reibschweißansatzelement 30.1 , relative to the longitudinal axis X , the locking element 30 ._; 30.8 is arranged on the radial lateral surface, as in 8th analogous to 6 is indicated.

In this embodiment, in turn, it is proposed as a relative movement between the housing structure 22 and latching element 30 ._; 30.8 an over a limited angle of rotation taking place reciprocating movement of the locking element 30 ._; 30.8 in the direction of the directional arrow P8 along the longitudinal axis X in the receiving channel 22:28 the housing structure 22 provided. As a result, the form-fitting and a reliable cohesive conical circumferential weld joint at least between the lateral surface of the conical foot part 37.2 and the to the locking element 30 ._; 30.8 facing inner surface of the through hole 22:28 the housing structure 22 achieved.

In this embodiment of the seventh embodiment, the stop plane and the so-called v-shaped friction welding plane fall apart.
