Abstract

The disclosure relates to a motor vehicle door lock, having a locking mechanism that includes a rotary latch and at least one pawl. A drive for acting on the locking mechanism is also provided. A blocking element which interacts with the pawl has at least one pawl arm which holds the pawl in a latching position. Finally, a stop arm is realized on the blocking element and/or on the pawl and/or on a release element, the stop arm acting as a stop for the drive. The blocking element is arranged on an edge which is averted from the rotary latch and also so as to laterally overlap the pawl.

First claim

The invention claimed is:

1. Motor vehicle door lock, having a locking mechanism comprising a catch and at least one pawl, as well as a drive for acting on the locking mechanism, and a blocking element interacting with the pawl with at least one pawl arm, holding the pawl in a detent position, and a stopping arm on the blocking element, acting as a stop for the drive, wherein the blocking element is arranged on an edge which is averted from the catch and also so as to laterally overlap the pawl, and wherein the pawl arm of the blocking element, in its position releasing the pawl, rests against a spring extension of the pawl.

2. Motor vehicle door lock according to claim 1 , characterized in that the pawl arm and the stopping arm on the blocking element form an angle that approximates a right angle.

3. Motor vehicle door lock according to claim 1 , characterized in that the stopping arm of the blocking element at least partially overlaps with a worm wheel of the drive.

4. Motor vehicle door lock according to claim 3 , characterized in that the worm wheel contains a radial projection extending upwards from the worm wheel in consideration of a specified angle of rotation and at a certain radial distance in relation to an axis.

5. Motor vehicle door lock according to claim 1 , characterized in that a first pawl and a second pawl are provided.

6. Motor vehicle door lock according to claim 5 , characterized in that the blocking element interacts with the first pawl.

7. Motor vehicle door lock according to claim 5 , characterized in that the two pawls are arranged in a plane above each other.

8. Motor vehicle door lock according to claim 1 , wherein the catch further comprises a plurality of ratchets.

9. Motor vehicle door lock, having a locking mechanism comprising a catch and a multi-pawl mechanism with a comfort pawl and a pre-ratchet pawl, as well as a drive for acting on the locking mechanism, and a blocking element interacting with the comfort pawl with at least one pawl arm, holding the comfort pawl in a detent position, and a stopping arm on the blocking element acting as a stop for the drive, characterized in that the blocking element is arranged on an edge which is averted from the catch and also so as to laterally overlap the comfort pawl.

10. Motor vehicle door lock according to claim 9 , characterized in that the pawl arm of the blocking element in its position releasing the comfort pawl, rests against an extension of the comfort pawl.

11. Motor vehicle door lock according to claim 10 , characterized in that the extension is designed as a spring extension.

12. Motor vehicle door lock according to claim 9 , characterized in that the stopping arm of the blocking element at least partially overlaps with a worm wheel of the drive.

13. Motor vehicle door lock according to claim 12 , characterized in that the worm wheel contains a radial projection extending upwards from the worm wheel in consideration of a specified angle of rotation and at a certain radial distance in relation to an axis.

14. Motor vehicle door lock according to claim 9 , characterized in that the comfort pawl and the pre-ratchet pawl are arranged in a plane above each other.

15. Motor vehicle door lock according to claim 9 , wherein the pawl arm and the stopping arm on the blocking element form an angle that approximates a right angle.

16. Motor vehicle door lock according to claim 9 , wherein the catch further comprises a plurality of ratchets.

17. Motor vehicle door lock according to claim 9 , wherein the catch further comprises a pre-ratchet pin that engages the pre-ratchet pawl.
