Abstract

The invention relates to a motor vehicle door lock which is equipped with a locking mechanism consisting substantially of a rotary latch and a pawl. A triggering element is additionally provided in order to lift the pawl and thereby open the locking mechanism. The motor vehicle door lock finally comprises an accumulator element which is impinged upon by a spring and which holds the pawl in the lifted position until the rotary latch is opened. According to the invention, the spring and the accumulator element form one component. Furthermore, the spring and the accumulator element are designed as a spring lip which impinges upon the trigger element.

Claims

1. Motor vehicle door lock with a locking mechanism including a catch and a pawl, furthermore with a release lever to lift off the pawl and thus open the locking mechanism, and with a buffer element actuated by a spring, which keeps the pawl in a lifted position until the catch is opened, thus characterized in that the spring and the buffer element form a constructional unit and are designed as a spring lip actuating the release lever.

2. Motor vehicle door lock in accordance with claim 1, characterized in that the spring and the buffer element are designed as a single piece and define the spring lip.

3. Motor vehicle door lock in accordance with claim 1, characterized in that the spring lip is connected to a housing (10) and/or a latch component.

4. Motor vehicle door lock in accordance with claim 3, characterized in that the spring lip is molded to the housing and/or the housing component.

5. Motor vehicle door lock in accordance with claim 3, characterized in that the spring lip and the housing and/or the latch component are designed as a single-component plastic component.

6. Motor vehicle door latch in accordance with claim 5, characterized in that the spring lip is mainly arranged tangentially compared to a pivoting movement described by the release lever.

7. Motor vehicle door latch in accordance with claim 6, characterized in that the spring lip interacts with a molding on the release lever.

8. Motor vehicle door latch in accordance with claim 7, characterized in that the spring lip crucially performs vertical deflecting movements compared to its lengthwise extension.

9. Motor vehicle door latch in accordance with claim 8, characterized in that the catch has a contour interacting with the spring lip.

10. Motor vehicle door latch in accordance with claim 9, characterized in that the contour on the catch lifts the spring lip off its rest on the release lever during the course of its opening movement.

11. Motor vehicle door lock in accordance with claim 1, characterized in that the spring lip is connected to a housing.

12. Motor vehicle door lock in accordance with claim 1, characterized in that the spring lip is connected to a latch component.

13. Motor vehicle door lock in accordance with claim 3, characterized in that the spring lip and the housing and/or the latch component are designed as a single-component plastic component.

14. Motor vehicle door latch in accordance with claim 1, characterized in that the spring lip is mainly arranged tangentially compared to a pivoting movement described by the release lever.

15. Motor vehicle door latch in accordance with claim 1, characterized in that the spring lip interacts with a molding on the release lever.

16. Motor vehicle door latch in accordance with claim 1, characterized in that the spring lip crucially performs vertical deflecting movements compared to its lengthwise extension.

17. Motor vehicle door latch in accordance with claim 1, characterized in that the catch has a contour interacting with the spring lip.

18. Motor vehicle door latch in accordance with claim 16, characterized in that the contour on the catch lifts the spring lip off its rest on the release lever during the course of its opening movement.
