Abstract

A motor vehicle door lock comprising a locking mechanism ( 1, 2 ) and a closing/opening device ( 7 to 16 ) with at least one drive ( 7 to 11 and 13, 14 ), at least one transfer element ( 12, 15 ) and a driving pawl ( 16 ), in which the drive acts on the driving pawl with the assistance of the transfer element to open and close the locking mechanism, wherein a mechanical and/or electrical opening drive ( 7 to 11 ) and a mechanical and/or electrical closing drive ( 13, 14 ) each with a respective opening transfer lever ( 12 ) and closing transfer lever ( 15 ) are provided, in which the opening drive ( 7 to 11 ) including the opening transfer lever ( 12 ) in addition to the opening function for the locking mechanism ( 1, 2 ) is also designed to interrupt a closing function initiated by the closing drive ( 13, 14 ) in connection with the closing transfer lever ( 15 ).

First claim

What is claimed is:

1. A motor vehicle door lock comprising:
a locking mechanism having a rotary latch and a pawl;
a driving pawl that rests on the rotary latch and is rotatable about an axis;
a mechanical and/or electrical opening drive;
a mechanical and/or electrical closing drive;
a closing transfer lever, wherein the closing drive acts on the closing transfer lever which acts on the driving pawl to rotate the rotary latch and close the locking mechanism;
an opening transfer lever that has an opening function for opening the locking mechanism and is also configured to interrupt a closing function initiated by the closing drive in connection with the closing transfer lever, wherein the opening transfer lever contains an actuating element that is configured as an actuating journal which during the opening function, lifts the pawl off the rotary latch of the locking mechanism; and
an upstream ejector lever that is rotatable about the axis of the driving pawl, the upstream ejector lever being independently rotatable about the axis relative to the driving pawl, wherein during the interruption of the closing function, the actuating element is moved via rotation of the opening transfer lever to engage and rotate the upstream ejector lever and the upstream ejector lever rotates to engage the driving pawl and lift the driving pawl off of the rotary latch while, at the same time, the actuating element also engages the pawl to lift the pawl off the rotary latch.

2. The motor vehicle door lock according to claim 1 , wherein the opening drive ejects the driving pawl in order to interrupt the closing function by means of the opening transfer lever.

3. The motor vehicle door lock according to claim 1 , wherein the upstream ejector lever and the driving pawl are mounted on an axis of the closing transfer lever.

4. The motor vehicle door lock according to claim 1 , wherein the opening transfer lever contains at least a drive arm and an actuating arm.

5. The motor vehicle door lock according to claim 1 , wherein an electrical opening drive and a mechanical opening drive are provided.

6. The motor vehicle door lock according to claim 5 , wherein the opening transfer lever interacts with a drive wheel of the electrical opening drive and/or a coupling element of the mechanical opening drive.

7. The motor vehicle door lock according to claim 6 , wherein the drive wheel contains a cam acting upon a drive arm of the opening transfer lever.

8. The motor vehicle door lock according to claim 6 , wherein the opening transfer lever interacts with the coupling element of the mechanical opening drive and the opening transfer lever is equipped with a connecting arm for the coupling element of the mechanical opening drive.

9. The motor vehicle door lock according to claim 1 , wherein the opening drive is equipped with a lever accessible in a passenger compartment and/or an electrical switching element for actuating the opening drive.
