Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door lock and a motor vehicle door lock provided with a substrate for a door outer handle.

[0002]

2. Description of the Related Art Such an automobile door lock is known. In the case of this motor vehicle door lock, the door lock and the door outer handle substrate are fixed to a support plate and together with this support plate form a prefabricated built-in module. This built-in module is inserted into the relevant car door. The fixing points for the built-in module of the motor vehicle door, i.e. for the door lock on the rear end plate of the motor vehicle and for the substrate on the door outer lamella, have errors. This error must be corrected during assembly. The support plate is flexible to correct errors in the running direction (X direction) and in the transverse direction (Y direction) with respect to the running direction, and the error correction in the vertical direction (Z direction) is performed by a rubber shock absorber. Will be The support plate is an additional component that is costly. Thus, the present invention takes measures.

[0003]

The object underlying the present invention is to provide a motor vehicle door lock of the kind mentioned at the outset, which omits the support plate and has a simple, easy to assemble and reliable construction. It is to be.

[0004]

In order to solve this problem, a motor vehicle door lock of the type mentioned at the outset has a substrate which can be connected via a plug-in device to a door lock, which plug-in device is at least vertically mounted. It is characterized in that predetermined assembly play is allowed in a direction transverse to the direction and the running direction. According to an embodiment of the invention, the plug-in device is formed as a locking fitting with a locking member provided on the base plate and a locking member receiver provided on the door lock or provided on the door lock. This is attained by being formed as a locking attachment joint having the locking member provided and the locking member receiver provided on the substrate. In any case, according to the present invention, there is provided an integrated module in which the door handle base plate and the door lock are connected and assembled to one another only via a bayonet or locking fitting, so that costly support plates can be omitted. Is achieved. Thus, overall, a very simple and reliable structure for the embedded module is achieved, furthermore the production costs are greatly reduced and the assembly operation is very efficient.

According to the proposal of the present invention, the locking member includes a locking arm having a locking head and a support plate as a back portion for the locking head, and the locking member receiver is provided in the depth direction. Movably, i.e., movably in the longitudinal direction, and rotatably, i.e., oscillating, comprising opposing locking legs for receiving locking heads therebetween, the locking legs together with the support legs;
It is provided with a plug-in part for receiving the support plate movably in the depth direction, that is, vertically, and rotatably, that is, rockingly. Thus, a prefabricated built-in module is obtained which saves material and which can correct errors with respect to the fixing points and thus during the assembly as follows. -In the Y direction, ie transversely to the running direction,
Therefore, with respect to the spacing of the screwing points for the door lock of the rear end plate and for the base plate of the door outer plate, by means of the depth movement of the locking mounting joint, in the Z direction, and thus in the vertical direction, Due to the swingability of the locking head and the adapter plate in the locking member receiver, by the adapter plate preventing sliding movement in the X direction and therefore in the direction of travel, so that the formed mounting joint cannot be separated. , Errors can be corrected.

Nevertheless, the entire locking member can be easily moved in the direction opposite to the running direction. This is because the holding legs are formed in a spring-elastic manner. Of course, the locking joint allows movement between the locking member receiver and the locking member so that the substrate slides and can be positioned and assembled correctly in contact with the door outer laminate. This is achieved by the elasticity of the material. This is because the locking member and the locking receiver are made of a bending elastic material, for example, a synthetic resin. The bending elasticity on the one hand allows a sufficient movement for the assembly on the one hand, and on the other hand, between the door lock and the board of the door outer handle,
A shape-fitting and friction-locking locking connection that can be accidentally released is achieved. The locking member and the locking member receiver can be formed as an integrally formed part or as separate parts.
In a separate component embodiment, this component is of course perfectly fixed to the door lock and the substrate. In this case, the catch or, if appropriate, the catch is provided on the lock cover of the door lock.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the drawings showing one embodiment. The figure shows an automobile door lock. This vehicle door lock has a door lock 1 and a door outer handle substrate 2 in a basic configuration. The board 2 can be connected to the door lock 1 via the plug-in device 3. In this case, the plug-in device has a certain assembly play at least in the vertical direction, ie in the Z direction, and transversely to the running direction, ie in the Y direction. The plug-in device is formed as a locking mounting connection device 3 with a locking member 4 provided on the base plate 2 and a locking member receiver 5 provided on the door lock 1. The locking member 4 includes a locking arm 6 having a locking head 7 and a support plate 8. This support plate forms the rear part for the locking head 7. Locking member receiver 5
The locking projections 10 receive the locking head 7 and can engage with the locking head from behind so as to be movable in the depth direction (i.e., the Y direction) and rotate or swing (i.e., the Z direction). And an opposing locking leg 9 having Tightening is performed between the locking head 7 and the locking leg 9.
The locking head 7 has an arc-shaped profile where it contacts the locking leg 9. As a result, the locking head 7 is rotatable in the locking member receiver 5 without expanding the locking legs 9. This locking leg would otherwise rotate the locking head back again. For integration, it is important that the locking arm 6 is bendable, that is, it has a minimum length and a diameter that allows it to bend. This bending is necessary so that the substrate 2 contacts the thin plate even when the locking head swings in the receiver. The locking leg 9 together with the support leg 11 form a plug-in component for accommodating the plate 8 so as to be movable in the depth direction (i.e. vertically movable) and rotatable or swingable. In this case, the locking leg 9 and the support cylinder 11 form, in particular, a triangle, for example an isosceles triangle. The support leg 11 is formed elastically (in the X direction).

The locking member 4 and the locking member receiver 5 are made of a bending elastic material, for example, a synthetic resin. In the embodiment,
The locking member 4 and the locking member receiver 5 are formed as molded parts. The locking member receiver 5 is on the lock cover 12. The movement and swing of the locking member 4 in the depth direction within the locking member receiver 5 are indicated by arrows as in the X, Y, and Z directions.
