The mounting device serves to receive an electrical plug coupling for the connection of an electronic circuit assembly. It has a coupling receptacle (2), which is pivotally mounted on a door handle carrier (10) and is locked against tilting in an installation position and can be pivoted into an operational position. The coupling receptacle (2) is guided by means of two formations (9) projecting on opposite sides in parallel guide slots (7). The guide slots (7) each have at least one slot constriction (8''), through which the formations (9) can be forced only after overcoming a predetermined threshold force. Rigidly connected to the coupling receptacle (2) is at least one tilt locking element (13b). The tilt locking element comes into engagement, in the installation position, with an opposing component (16) fixed to the door and then comes out of engagement with the opposing component when the formations (9) have passed the slot constrictions (8'') in the guide slots (7).

Description

The invention relates to a door handle support with a mounting device for an electrical plug-in coupling to a built-in door handle electronic circuitry with a hinged to the door handle carrier coupling receptacle which is tilt-protected in a first mounting position and movable from the mounting position to an operating position.

From the DE 100 62 042 B4 a door handle support of this type is known in which a plug-in coupling part is connected via a short cable to the door handle and can be inserted in a mounted on the door handle carrier coupling receptacle. The coupling receptacle is pivotally mounted between a mounting position and an operating position on the carrier. In the mounting position, the coupling receptacle can be locked by a locking device which provides the necessary counterforce for inserting the plug-in coupling in the receptacle. The locking device consists of a molded-on the coupling receptacle nose and a carrier-fixed locking receptacle. The cooperating locking elements must be formed in relatively tight tolerances, so on the one hand, the locking force is sufficient for insertion of the plug-in coupling and on the other hand pivoting back of the coupling receptacle after making the connector damage-free possible. For this purpose, the bearing tolerances of the coupling receptacle in the pivot bearing and the tolerances of the cooperating in the mounting position latching elements must be matched relatively accurately, which requires a corresponding production cost.

The invention is therefore based on the object, the door handle support in such a way that a reliable Kippsicherung the coupling receptacle in the mounting position and a easy transfer to an operating position with relatively simple means is possible.

In the solution of this problem, the invention is based on the consideration that the functions of the lock in the mounting position and the release of the lock for the transfer of the coupling receptacle in the operating position structurally and functionally different components must be assigned.

Starting from a door handle support of the type mentioned, the invention solves the underlying object in that the coupling receptacle is guided over two opposite sides projecting lugs in parallel guide slots of the door handle support pivotally mounted support member, wherein the guide slots have at least one slot narrowing at corresponding locations , which is passable from the approaches only by overcoming a predetermined threshold force, and that at least one Kippsicherungselement is firmly connected to the coupling receptacle, the Kippsicherungselement can come into the mounting position with a door-mounted counter-component for anti-tip into abutment and the repeal of the counter-component is released after the approaches have passed the slot constrictions in the guide slot, and wherein after lifting the anti-tip device, the holding member together with the coupling receptacle in the Bet rubbing position is pivotable.

By subdividing the mounting device into a coupling receptacle and a retaining component, it is possible to assign the functions of the tilt protection on the one hand and the slot narrowing effecting the locking to different elements. The anti-tilt device can be realized by a simple stop between the coupling holder and the handle carrier. The vote of the parallel guide slots on the cross sections of the protruding from the coupling receptacle approaches is technologically also no problem. Upon displacement of the coupling receptacle relative to the outer support member, the anti-tilt device is released, and the support member can be easily in the together with the coupling receptacle in the Swing operating position. Special requirements regarding the dimensional stability of the pivot bearing is not required.

In a further development of the invention it is provided that at least one guide runner is formed as Kippsicherungselement to the coupling receptacle and extends substantially parallel to the insertion of the plug-in coupling. Since the guides on the one hand and the plug-in direction of the plug-in coupling on the other hand are substantially parallel, the guide run can be moved out of the stop area on the door handle carrier with linear movement of the coupling receptacle, after which the holding member can be pivoted with the coupling receptacle in the operating position.

In a preferred embodiment of the invention, the anti-tilt mating component is designed as a carrier-solid guide groove, which receives the adjacent blade in the mounting position and thereby runs substantially parallel to the guide slots of the support member. Preferably, the coupling receptacle is provided with two symmetrically arranged parallel guide runners, which engage in corresponding carrier-fixed guide grooves, while the coupling receptacle is in the mounting position.

A preferred embodiment of the invention is characterized in that each guide slot is provided with two slot constrictions, wherein a first slot constriction is disposed near a slot end and the second slot constriction defines that position of the receptacle in which the system of the anti-tilt element is lifted to a door-mounted counterpart component.

The in the Fig. 1 and 2 The holding device 3 is provided via a bearing arm 4 with a pivot bearing 5 and via the pivot bearing 5 with a door handle support 10 (FIG. 2). Fig. 3 ) connected. The holding member has a fork-shaped holder with two parallel rails 6a, 6b, which are integrally formed on a yoke 17 connected to the bearing member. In each rail 6a and 6b, a guide slot 7 is formed in the form of a slot. Near the in Fig. 1 shown rear end of the guide slot 7 is a first slot constriction 8 'and approximately in the middle of the slot 7, a second slot constriction 8 "arranged.

The coupling receptacle 2 has an approximately C-shaped, stepped cross-sectional profile and offers a plug-in coupling inserted in the receiving interior (not shown) all-round grip. The coupling receptacle 2 is mounted on opposite sides projecting lugs 9 in the guide slot 7. The coupling receptacle 2 can along the linear guideway in the slot 7 of the in Fig. 3 shown right End position to be moved to the opposite end position. For this purpose, the threshold forces must be overcome between the two-sided lugs 9 and the two slot constrictions 8 'and 8 "The required threshold force is adjusted so that they the expected insertion force when inserting the coupling part (plug) in the already in the recording The lugs 9 may be designed in the manner of bearing journals, in the illustrated embodiment they have a lug protruding in the longitudinal direction of the slot 7. The coupling lug 2 has projections projecting towards opposite sides Guide ribs 11a and 11b, which are formed and arranged so that they can be in contact with slideways 12a and 12b of the parallel bearing rails 6a and 6b, thereby holding the guided in the guides 7 receiving member 2 in a aligned with the holding member 3 position aligned position remains even then maintained when the receptacle 2 along the guide rails 6a and 6b displaced in the longitudinal direction and both components are pivoted together about the bearing axis 5.

On the receptacle 2 also two guide skids 13a and 13b are formed. The guide run substantially parallel to the receiving axis 14 (FIG. Fig. 3 ) of the receiving member 2 and to the guide slots 7 in the bearing rails 6a and 6b of the holding member. The guide runners 13a, 13b serve, as described below with reference to FIG Fig. 3 to 8 will be explained, the anti-tip device of the mounting device 1 in the mounting position according to Fig. 7 , In this case, the skids can be supported on the two carrier-fixed, parallel ribs 16, which each secure a skid in the mounting position of the holding device 1 against tilting.

The following are based on the Fig. 3 to 5 the intended positions of the two-part mounting device 1 relative to the handle support 10 and the relative positions of the two parts 2 and 3 of the mounting device 1 in the various Positions and the transition between operating and assembly position explained.

Fig. 3 and 4 illustrate the mounting device 1 in a delivery state at the customer after attachment to the handle support 10. In the delivery position, the coupling receptacle 2 is in the in Fig. 4 right end position, wherein the laterally projecting lugs 9 are engaged at the slot end behind the first slot constriction 8 '. In this position, the installation of the (not shown) jack with cable connection to the vehicle / vehicle control unit.

Thereafter, the coupling holder 2 is moved overcoming the predetermined threshold forces between the slot constrictions 8 'and 8 "and engaging in the slots pin-shaped projections 9, the left end position ( Fig. 5 ). This position corresponds to the later operating position and is the starting position for pivoting the mounting device 1 in the mounting position.

Fig. 6 shows an intermediate position of the holder device 1 in a position before the engagement of the guide runners (in Fig. 6 only the guide skid 13a can be seen) in a formed between the two carrier-solid parallel ribs 16 receiving groove. The coupling receptacle 2 is held during pivoting in the upper end position, so that the guide skids 13a and 13b can be moved freely over the left rib 16. Thereafter, the bearing arm 4 is further pivoted to a fixed to the handle support 10 stop 18, whereby the guide skids 13 a and 13 b are brought into alignment with the grooves formed between the ribs 16. It follows the displacement of the coupling receptacle 2 along the slot 7 down to the mounting position, in Fig. 7 is shown. In this mounting position, the lugs are trapped behind one of the two slot constrictions 8 'and 8 "At the same time, the runners 13a engage in the groove between the carrier-fixed ribs 16 and act as anti-tilt device, whereby pivoting back of the swivel arm 4 with the holding device 1 is prevented The mounting device 1 therefore has in the assembly position according to Fig. 7 a positionally stable and tilt-proof position, held by the slot constrictions 8 'in cooperation with the pin 9 (FIG. Fig. 1 and 3 ) and engaging in the grooves between the ribs 16 skids 13 a and 13 b. In this mounting position ( Fig. 7 ), the handle support 10 is mounted on the vehicle from the inside, whereupon from the outside of the plug (not shown) in the in Fig. 7 below narrower portion of the coupling receptacle 2 and in the already inserted into the extended portion of the coupling receptacle coupling socket (also not shown) is inserted.

After completion of the coupling process between the socket and plug, the assembly of the handle, also not shown in the drawing, which is connected to the plug.

The coupling receptacle 2 is moved after overcoming the threshold force at the first slot constrictions 8 'in the direction of the slot 7 to the second detent at the slot constriction 8 ", wherein the direction of movement is held by the resting on the ribs 16 in contact pads 13a corresponding to the mounting position and tilted The second latch 8 "ensures that the plug is properly coupled to the socket. Only after overcoming the threshold force at the second latching point 8 "is the coupling receptacle 2 extended as far as the upper slot end (FIG. Fig. 8 ) that the runners 13a are completely excavated from the groove formed between the ribs 16 ( Fig. 9 ), so that the two-part mounting device 1 under pivoting of the bearing arm 4 ( Fig. 6 ) in the operating position according to Fig. 5 fold back.

As is apparent from the above description, the functions of locking the mounting position by the interaction of the slot constrictions 8 'and 8 "and the bearing pin 9 on the one hand and the anti-tip by the interaction of the guide runners 13a and 13b and the ribs 16 are different and in pairs The adjacent components can be matched very precisely with relatively little production effort.

In principle, a latching point (eg the slot constriction 8 ') is sufficient for the locking in the assembly position ( Fig. 7 ) out. The second slot constriction 8 "arranged at a distance from the first slot constriction 8 ', however, increases the reliability of the production of the coupling connection between the coupling components, not shown in the drawing, ie the socket with the plug on the handle side only after overcoming the threshold force at the detent position 8" lifted the anti-tilt device formed between the components 13a, 13b and 16.

Instead of the pair of ribs 16 shown in the figures, which delimit a guide groove laterally, a single rib 16 can fulfill the Kippsicherungsfunktion. Furthermore, the skids 13a may be integrally formed on the lugs 9 in a modified embodiment. The at least one rib of the handle carrier must then be arranged so that they in the mounting position ( Fig. 7 ) cooperates with the projecting runner on the adjacent approach and ensures the anti-tip device in the mounting position.
