Abstract

A method for closing and opening a motor vehicle lock door and to a motor vehicle lock includes a locking mechanism with a rotary latch and at least one pawl, a rotational movement of the rotary latch being lockable in at least one latching position by means of the pawl, a closing device, wherein the locking mechanism can be transferred from a pre-latching position into a main latching position by means of the closing device, and an opening device, wherein a door element can be transferred from a closing position into an open position by means of the opening device, and wherein a coupling element can be controlled by a drive device such that an opening and closing of the door element can be made possible by means of the closing device.

Claims (22)

1 . A motor vehicle lock comprising:

a locking mechanism with a rotary latch and at least one pawl, a rotational movement of the rotary latch being lockable in at least one latching position by the pawl,

a closing device, wherein the locking mechanism is transferred from a pre-latching position into a main latching position by the closing device,

an opening device,

a door element, and

a coupling element,

wherein the door element is transferred from a closing position into an open position by the opening device, and wherein the coupling element is controlled by a drive device such that an opening and closing of the door element is controlled via the closing device, and

wherein the coupling element is a coupling lever, and the coupling lever is mounted on an operating lever for the closing device.

2 . The motor vehicle lock according to claim 1 , wherein the drive device is part of the motor vehicle lock.

3 . The motor vehicle lock according to claim 1 , wherein the drive device is integrated into the motor vehicle lock.

4 . The motor vehicle lock according to claim 1 , further comprising at least one further function element, wherein the at least one further function element is engaged and/or actuated by the drive device.

5 . The motor vehicle lock according to claim 1 , wherein the closing device is accommodated at least partially in the motor vehicle lock or completely independently of the motor vehicle lock in the motor vehicle.

6 . The motor vehicle lock according to claim 1 , wherein an operative connection between the opening device and the closing device is provided by the coupling element.

7 . The motor vehicle lock according to claim 1 , wherein the closing device is mechanically coupled to the opening device by the coupling element.

8 . The motor vehicle lock according to claim 1 , further comprising a positioner for the opening device, wherein the door element is held by the positioner for the opening device.

9 . The motor vehicle lock according to claim 8 , further comprising a lock holder, wherein the positioner is engageable with the lock holder.

10 . The motor vehicle lock according to claim 8 , wherein the positioner is arranged parallel to the rotary latch.

11 . The motor vehicle lock according to claim 1 , wherein the coupling element is a mechanical coupling with a sliding element.

12 . The motor vehicle lock according to claim 1 , wherein the coupling element is pivotably received in the motor vehicle lock.

13 . The motor vehicle lock according to claim 1 , wherein the coupling element has at least one control bolt, and the at least one control bolt is guided in a control contour.

14 . The motor vehicle lock according to claim 1 , wherein the opening device has a lever mechanism.

15 . The motor vehicle lock according to claim 1 , wherein the closing device directly engages with the rotary latch.
