Abstract

The invention relates to a motor vehicle door closure, comprising a locking mechanism, an electric drive (3, 4) for the locking mechanism, and a child-restraint element (14) with a corresponding sensor (15). The electric drive (3, 4) can be activated or deactivated in order to open the locking mechanism dependant on the position of the child-restraint element (14), said position being requested using the sensor (15). The activated child-restraint element (14) can be deactivated in an emergency operation by a switch (17), and the locking mechanism can be opened by the electric drive (3, 4).

Claims

1. Motor vehicle door closure comprising a locking mechanism, an electric drive (3, 4) for the locking mechanism and a child-restraint element (14) with a corresponding sensor (15), in which depending on the position of the child-restraint element (14) detected by the sensor (15) the electric drive (3, 4) can be activated or deactivated regarding the opening of the locking mechanism, characterized in that during an emergency operation the activated child-restraint element (14) can be deactivated by a switch (17) and that the locking mechanism can be opened by the electric drive (3, 4).

2. Motor vehicle door closure according to claim 1 characterized in that at least one switch (17) is assigned to the child-restraint element (14), optionally providing a temporary electric deactivation of the activated child restraint.

3. Motor vehicle door closure according to claim 2, characterized in that the switch (17) is a dashboard switch (17) inside a motor vehicle and is at the same time a locking and unlocking switch.

4. Motor vehicle door closure according to claim 1, characterized in that a control unit (16) is provided, with the aid of which individual child-restraint elements (14) are optionally activated/deactivated and which evaluates the respective switch (17) and acts on the respective electric drive (3, 4) accordingly.

5. Motor vehicle door closure according to claim 1, characterized in that the child-restraint element (14) interacts with a coupling lever (6) by means of a follower (12).

6. Motor vehicle door closure according to claim 5, characterized in that the coupling lever (6) couples the follower (12) to a locking lever (10).

7. Motor vehicle door closure according to claim 5, characterized in that the coupling lever (6) is displaceably arranged on the actuating lever (5).

8. Motor vehicle door closure according to claim 5, characterized in that the follower (12) and the coupling lever (6) permit movements of the locking lever (10) in the deactivated position of the child-restraint element (14).

9. Motor vehicle door closure according to claim 7, characterized in that the follower (12) and the coupling lever (6) hold the locking lever (10) in its “

locked”

position when the child-restraint element (14) is in activated position.

10. Motor vehicle door closure according to claim 7, characterized in that the coupling lever (6) mechanically couples the actuating lever (5) to a triggering lever (1) or causes an idle stroke of the actuating lever (5) in relation to the triggering lever (1) depending on the position of the coupling lever (6) on the actuating lever (5).

11. Motor vehicle door closure according to claim 1, characterized in that the actuating lever (5) and the triggering lever (1) are arranged on the same axis.

12. Motor vehicle door closure according to claim 5, characterized in that the coupling lever (6) contains two actuating journals (79).

13. Motor vehicle door closure according to claim 12, characterized in that the one actuating journal (9) is a locking pin and extends through the locking lever (10) and a recess (13) in the follower (12).

14. Motor vehicle door closure according to claim 12, characterized in that the other actuating journal (7) on the coupling lever (6) extends through a (8) recess in the actuating lever (5).

15. Motor vehicle door closure according to claim 6, characterized in that the coupling lever (6) is displaceably arranged on the actuating lever (5).

16. Motor vehicle door closure according to claim 15, characterized in that the follower (12) and the coupling lever (6) permit movements of the locking lever (10) in the deactivated position of the child-restraint element (14).

17. Motor vehicle door closure according to claim 16, characterized in that the follower (12) and the coupling lever (6) hold the locking lever (10) in its “

locked”

position when the child-restraint element (14) is in activated position.

18. Motor vehicle door closure according to claim 17, characterized in that the coupling lever (6) mechanically couples the actuating lever (5) to a triggering lever (1) or causes an idle stroke of the actuating lever (5) in relation to the triggering lever (1) depending on the position of the coupling lever (6) on the actuating lever (5).

19. Motor vehicle door closure according to claim 18, characterized in that the actuating lever (5) and the triggering lever (1) are arranged on the same axis.

20. Motor vehicle door closure according to claim 19, characterized in that the coupling lever (6) contains two actuating journals (79).
