Abstract

A motor vehicle door lock, comprising a locking mechanism (1, 2), and a closing/opening device (3 to 7) having a drive, wherein the closing/opening device (3 to 7) acts on the locking mechanism (1, 2), and wherein-the closing/opening device (3 to 7) contains an interposed damping element (16).

Claims

1. A motor vehicle door lock, comprising:

a locking mechanism (1, 2), and a closing/opening device (3 to 7) having a drive, wherein the closing/opening device (3 to 7) acts on the locking mechanism (1, 2), and wherein the closing/opening device (3 to 7) contains an interposed damping element (16).

2. The motor vehicle door lock according to claim 1, wherein the damping element (16) is predominantly made from an elastomer.

3. The motor vehicle door lock according to claim 1, wherein the damping element (16) transfers rotary movements of a motor (3a) of the drive (3, 4, 5) to as downstream actuator (4, 5).

4. The motor vehicle door lock according to claim 1, wherein the damping element (16) is designed as a drive belt 6) and/or claw coupling (16a, 16b).

5. The motor vehicle door lock according to claim 1, wherein the damping element (16) is integrated in a drive train of a motor (3a) of the drive (3, 4, 5).

6. The motor vehicle door lock according to claim 5, wherein the damping element (16) connects two components of the drive train of the motor (3a).

7. The motor vehicle door lock according to claim 1, wherein the drive (3, 4, 5) is designed as a linear drive (3, 4, 5).

8. The motor vehicle door lock according to claim 1, wherein the drive (3, 4, 5) comprises at least a motor (3a) and an actuator (4, 5).

9. The motor vehicle door lock according to claim 8, wherein the motor (3a) and the actuator (4, 5) are positioned at an angle and, in particular, at right angles to each other.

10. The motor vehicle door lock according to claim 8, wherein the actuator (4, 5) is a linear actuator (4, 5) and contains a spindle element (4).
