Abstract

A motor vehicle lock, in particular an electrically actuatable motor vehicle lock, comprising a locking mechanism having a rotary latch and at least one pawl, a release lever, wherein the release lever can be actuated by means of an electric drive unit and at least one manually actuatable actuating lever, and wherein the release lever interacts with the locking mechanism in such a way that a blocked locking mechanism can be unblocked, and a locking unit, wherein manual unblocking of the locking mechanism can be prevented by means of the locking unit, and wherein simultaneous locking of the actuating lever and unblocking of the locking mechanism can be made possible by means of the drive unit.

First claim

The invention claimed is:

1. An electrically actuatable motor vehicle lock, comprising:
a locking mechanism having a rotary latch and at least one pawl, a release lever, wherein the release lever interacts with the locking mechanism in such a way that a blocked locking mechanism can be unblocked,
an electric drive unit and a manually actuatable actuating lever, wherein the release lever is actuatable by either one of the electric drive unit and the manually actuatable actuating lever,
a locking unit, wherein manual unblocking of the locking mechanism is prevented by the locking unit, wherein the drive unit is configured to permit simultaneous locking of the manual actuatable actuating lever and unblocking of the locking mechanism, and
a control lever,
wherein the drive unit includes a control member,
wherein the control member engages with the release lever in such a way that the control member blocks a movement of the control lever during actuation of the release lever, and
a coupling lever that is arranged between the actuating lever and the release lever,
wherein the coupling lever is configured such that when the actuating lever is actuated with a conventional actuation speed the coupling lever engages with the release lever and unblocks the locking mechanism, and when the control lever is blocked by the control member, then, when the actuating lever is moved, the coupling lever is deflected and the release lever is not actuated.

2. The motor vehicle lock according to claim 1 , wherein the drive unit further includes an electric drive, a drive gear, and a drive pulley.

3. The motor vehicle lock according to claim 2 , wherein the actuating lever engages with the release lever via the control lever.

4. The motor vehicle lock according to claim 3 , wherein the control lever is blocked and released by the control member.

5. The motor vehicle lock according to claim 3 , wherein the release lever is mounted on a common axis with the control lever and the actuating lever.

6. The motor vehicle lock according to claim 2 , wherein the release lever is actuated by the control member.

7. The motor vehicle lock according to claim 2 , wherein the control member engages with a control contour of the control lever during actuation of the release lever.

8. The motor vehicle lock according to claim 7 , wherein the control member includes a control cam that engages with the control contour of the control lever.

9. The motor vehicle lock according to claim 2 , wherein the control member is transferred by the drive unit into a release position in which the control lever is released and into a blocking position in which the control lever is blocked.

10. The motor vehicle lock according to claim 2 , wherein the control lever interacts with a mass inertia-based securing system.

11. The motor vehicle lock according to claim 2 , wherein the control member is pivotable and the release lever has an extension that extends into a pivoting range of the control member.

12. An electrically actuatable motor vehicle lock, comprising:
a locking mechanism having a rotary latch and at least one pawl,
a release lever, wherein the release lever interacts with the locking mechanism in such a way that a blocked locking mechanism can be unblocked,
an electric drive unit and a manually actuatable actuating lever, wherein the release lever is actuatable by either one of the electric drive unit and the manually actuatable actuating lever,
a locking unit, wherein manual unblocking of the locking mechanism is prevented by the locking unit, and wherein the drive unit is configured to permit simultaneous locking of the manual actuatable actuating lever and unblocking of the locking mechanism, and
a coupling lever that is arranged between the actuating lever and the release lever,
wherein the coupling lever is configured such that when the actuating lever is actuated with a conventional actuation speed the coupling lever engages with the release lever and unblocks the locking mechanism, and when the control lever is blocked by the control member, then, when the actuating lever is moved, the coupling lever is deflected and the release lever is not actuated.

13. An electrically actuatable motor vehicle lock, comprising:
a locking mechanism having a rotary latch and at least one pawl,
a release lever, wherein the release lever interacts with the locking mechanism in such a way that a blocked locking mechanism can be unblocked,
an electric drive unit and a manually actuatable actuating lever, wherein the release lever is actuatable by either one of the electric drive unit and the manually actuatable actuating lever,
a locking unit, wherein manual unblocking of the locking mechanism is prevented by the locking unit, and wherein the drive unit is configured to permit simultaneous locking of the manual actuatable actuating lever and unblocking of the locking mechanism, and
a control lever, wherein the actuating lever engages with the release lever via the control lever,
wherein the drive unit has an electric drive, a drive gear, a drive pulley, and a control member, and
wherein the release lever is mounted on a common axis with the control lever and the actuating lever.
