Abstract

The invention relates to a motor vehicle locking device comprising a locking mechanism having a rotary latch and at least one pawl, an actuating lever mechanism acting on the pawl, and a child safety device having a control element ( 1 ), wherein the control element ( 1 ) is latchable in at least two latching positions (R 1 , R 2 ), and a spring element ( 3 ) on the control element ( 1 ), wherein the spring element ( 3 ) interacts with a control cam ( 2 ) in such a way that the control element ( 1 ) is adjustable in a spring-loaded manner into the latching positions (R 1 , R 2 ), and wherein the spring element ( 3 ) is designed as a spring lip ( 3 ).

First claim

The invention claimed is:

1. A motor vehicle locking device comprising:
a child safety device having a control element that includes a spring element; and
a support,
wherein:
the control element is latchable in at least two latching positions, and the spring element interacts with a control contour in such a way that the control element is adjustable in a spring-loaded manner into either of the latching positions,
the spring element is a spring lip,
the control element includes a cavity that extends within the control element,
the support extends in the cavity, and
the support is brought into engagement with the spring element at least while the control element is being adjusted,
wherein the control element is in engagement with a control contour that is part of a locking housing.

2. The motor vehicle locking device according to claim 1 , wherein the spring lip has a thickened portion configured as a spring tab.

3. The motor vehicle locking device according to claim 1 , wherein the spring lip is pivotable into the control element.

4. The motor vehicle locking device according to claim 1 , wherein the support is pivotable by the spring lip until the support abuts a stop surface of the control element.

5. The motor vehicle locking device according to claim 1 , wherein the control element is made of a plastics material and is configured in one piece with the spring lip and the support.

6. The motor vehicle locking device according to claim 1 , wherein the spring lip and the support are formed opposite one another on the control element.

7. The motor vehicle locking device according to claim 6 , wherein the control element is pivotable via an engagement contour to adjust the control element.

8. The motor vehicle locking device according to claim 1 , wherein the control element includes a guide surface that acts as a stop for the control element.

9. The motor vehicle locking device according to claim 1 , wherein the control element is cylindrical.

10. The motor vehicle locking device according to claim 1 , wherein the support is further brought into engagement with a wall of the cavity.

11. The motor vehicle locking device according to claim 1 , wherein the spring element defines a portion of the cavity.

12. A motor vehicle locking device comprising:
a child safety device having a control element that includes a spring element; and
a support,
wherein:
the control element is latchable in at least two latching positions, and the spring element interacts with a control contour in such a way that the control element is adjustable in a spring-loaded manner into either of the latching positions,
the spring element is a spring lip,
the control element includes a cavity that extends within the control element,
the support extends in the cavity, and
the support is brought into engagement with the spring element at least while the control element is being adjusted,
wherein the spring element defines a portion of the cavity.
