Abstract

The invention relates to a motor vehicle door lock comprising a locking mechanism, also at least one locking element ( 3 ), an electric drive ( 5, 6, 7 ) for the locking mechanism, and at least two stops ( 20, 21, 22, 27 ) for the electric drive ( 5, 6, 7 ) and/or the locking element ( 3 ), wherein one of the stops ( 20, 21 ) is associated with the locking element ( 3 ) and the other stop ( 22, 27 ) is associated with the electric drive ( 5, 6, 7 ) and both stops ( 20, 21, 22, 27 ) are arranged on a common stop contour ( 23 ).

First claim

The invention claimed is:

1. A motor vehicle door lock comprising:
a locking mechanism;
at least one lock element;
an electric drive for the locking mechanism that includes an electric motor and at least one gear; and
a stop part having at least two stops arranged on a common contour of the stop part, wherein a first stop interacts with an element of the at least one lock element and a second stop interacts with the at least one gear of the electric drive, wherein the first stop includes two stop sides that interact with the lock element to restrict movement of the lock element.

2. The motor vehicle door lock according to claim 1 , wherein the lock element is a pivoted lever.

3. The motor vehicle door lock according to claim 1 , wherein the two stop sides belong to different functional positions.

4. The motor vehicle door lock according to claim 1 , wherein the second stop for the electric drive is an end stop.

5. The motor vehicle door lock according to claim 1 , wherein during normal operation the electric drive impinges upon the locking mechanism for electric opening and also provides a mechanical opening of the locking mechanism at least during emergency operation.

6. The motor vehicle door lock according to claim 1 , wherein the electric drive comprises at least one electric motor, a worm gear driven by said motor and a driven wheel gear meshing with the worm gear.

7. The motor vehicle door lock according to claim 1 , wherein the stop part is a unitary component with a plurality of stops formed thereon.

8. The motor vehicle door lock according to claim 1 , wherein the stop part is an injection-moulded part.

9. The motor vehicle door lock according to claim 1 , wherein cavities are assigned to each stop for damping.

10. The motor vehicle door lock according to claim 1 , wherein the stop part is formed of an elastic material.

11. The motor vehicle door lock according to claim 1 , wherein the stop part is arch-shaped with thicker sections at its ends.

12. The motor vehicle door lock according to claim 1 , wherein the stop part is mechanically connected to or forms a single piece with a lock cover.

13. A motor vehicle door lock comprising:
a locking mechanism;
at least one lock element;
an electric drive for the locking mechanism that includes an electric motor and at least one gear; and
a stop part having at least two stops arranged on a common contour of the stop part, wherein a first stop interacts with an element of the at least one lock element and a second stop interacts with the at least one gear of the electric drive;
wherein the lock element is a locking lever and the locking lever includes two stop sides for restricting movement of the lock between a locked or unlocked functional position.
