Abstract

A detent mechanism for a motor vehicle component has a pivotable holding part and a pivotable blocking part. The holding part is pivotable into a closing position and an open position about a holding part axis. A blocking state is produced by the blocking part being pivotable into a blocking position in which a blocking surface of the blocking part and a blocking surface of the holding part are in blocking engagement with each other and block a pivoting movement of the holding part out of the closing position in the direction of the open position. The blocking part is pivotable into a release position in which the blocking surfaces are disengaged from each other and release the holding part. In some cases, in the blocking state, a supporting surface of the blocking part and a supporting surface of the holding part are in axially supporting engagement with each other.

First claim

What is claimed is:

1 . A detent mechanism for a motor vehicle component, the detent mechanism comprising:
a pivotable holding part; and a pivotable blocking part; wherein the holding part is pivotable into a closing position and into an open position about a holding part axis; wherein a blocking state is produced by the blocking part being pivotable into a blocking position in which a blocking surface of the blocking part and a blocking surface of the holding part are in blocking engagement with each other and block a pivoting movement of the holding part out of the closing position in the direction of the open position; wherein the blocking part is pivotable into a release position in which the blocking surfaces are disengaged from each other and release the holding part; and wherein, in the blocking state, with respect to the holding part axis, between the blocking surfaces, a supporting surface of the blocking part and a supporting surface of the holding part are in axially supporting engagement with each other or can be brought into axially supporting engagement with each other.

2 . The detent mechanism of claim 1 , wherein, during normal operation, the supporting surface of the holding part and the supporting surface of the blocking part form a gap.

3 . The detent mechanism of claim 1 , wherein, in the blocking state, the supporting engagement is provided in the vicinity of the blocking engagement.

4 . The detent mechanism of claim 1 , wherein the supporting surface of the blocking part is an integral component of the blocking part, and/or wherein the supporting surface of the holding part is an integral component of the holding part.

5 . The detent mechanism of claim 1 , wherein at least one of the supporting surface of the blocking part and the supporting surface of the holding part runs substantially perpendicularly to the holding part axis.

6 . The detent mechanism of claim 1 , wherein at least one of the blocking surface of the blocking part and the blocking surface of the holding part runs substantially along the holding part axis.

7 . The detent mechanism of claim 1 , wherein the supporting surface of the blocking part and the supporting surface of the holding part are arranged with respect to the blocking surface of the blocking part and/or the blocking surface of the holding part in a manner offset axially with respect to the holding part axis.

8 . The detent mechanism of claim 1 , wherein the holding part is a lock latch of a motor vehicle lock, wherein the lock latch, in the closing position, is in holding engagement with a striker, and wherein the blocking part is a pawl of the motor vehicle lock.

9 . The detent mechanism of claim 8 , wherein the lock latch is of substantially disk-shaped design, wherein the blocking surface of the lock latch is arranged on an outer circumference of the lock latch, and wherein the supporting surface of the lock latch is arranged on a flat side of the lock latch.

10 . The detent mechanism of claim 9 , wherein both the supporting engagement and the blocking engagement are provided in the region of the outer circumference of the lock latch.

11 . The detent mechanism of claim 8 , wherein the supporting surface of the pawl is a component of a supporting tab that protrudes from the pawl, and wherein the supporting tab is bent away from the pawl.

12 . The detent mechanism of claim 11 , wherein the supporting tab provides an engagement depth limit.

13 . The detent mechanism of claim 11 , wherein the pawl is designed as a punched and bent part.

14 . The detent mechanism of claim 11 , wherein the supporting tab comes into engagement with a limit contour at a predetermined engagement depth of the pawl.

15 . The detent mechanism of claim 14 , wherein the limit contour is arranged on the lock latch.

16 . A motor vehicle component, comprising the detent mechanism of claim 1 .

17 . The motor vehicle component of claim 16 , wherein the motor vehicle component is a motor vehicle lock, wherein the holding part is a lock latch of the motor vehicle lock, wherein the lock latch, in the closing position, is in holding engagement with a striker, and the blocking part is a pawl of the motor vehicle lock, and wherein a striking plate is provided for receiving bearing pins for the lock latch and the pawl, and wherein, in the blocking state, the lock latch is enclosed between the supporting surface of the pawl and the striking plate.

18 . The motor vehicle component of claim 17 , wherein, in the fitted state, a holding force acting on the striker leads to deformation of the motor vehicle lock, the deformation being substantially associated with an axial shifting of the blocking surface of the lock latch, and wherein the blocking surface of the pawl substantially follows the axial shifting due to the supporting engagement between the supporting surfaces.

19 . The motor vehicle component of claim 17 , wherein, in the fitted state, a crash-induced holding force acting on the striker leads to deformation of the motor vehicle lock, the deformation being substantially associated with an axial shifting of the blocking surface of the lock latch, and wherein the blocking surface of the pawl substantially follows the axial shifting due to the supporting engagement between the supporting surfaces.
