Abstract

A lock mechanism ( 1 ) for a motor vehicle lock ( 2 ) comprising a rotary catch ( 6 ), a pawl ( 9 ) for positive locking the catch ( 6 ) in a preliminary-closed stop position ( 8 ) as well as in a fully-closed stop position ( 7 ), and a blocking lever ( 14 ) for blocking the pawl ( 9 ) when the pawl ( 9 ) is in its preliminary-closed position ( 8 ) as well as in its fully-closed stop position ( 7 ).

First claim

What is claimed is:

1. Lock mechanism for a motor vehicle lock comprising a rotary catch, a pawl for positive locking the catch in a preliminary-closed stop position as well as in a fully-closed stop position, and a blocking lever for blocking the pawl when the pawl is in its preliminary-closed position as well as in its fully-closed stop position;
wherein the blocking lever has two lever arms which are arranged in opposite directions to a blocking lever rotation axis, wherein one lever arm acts as a blocking lever release arm with a pawl driver arm, and the other lever arm possesses a blocking arm with a blocking surface for the pawl.

2. Lock mechanism according to claim 1 , further comprising a release lever that is activated to move the blocking lever from blocking the pawl in the preliminary-closed stop position and fully-closed stop position, wherein the blocking lever is designed so that it can overtravel the pawl from its preliminary-closed stop position as well as from its fully-closed stop position when the release lever is activated.

3. Locking mechanism according to claim 1 , wherein the blocking lever, is blocking the pawl via the blocking arm in pawl fully-closed position as well as in pawl preliminary-closed position when the blocking arm surface contacts the blocking surface of the pawl in pawl opening direction.

4. Locking mechanism according to claim 1 , wherein the blocking lever ensures that the pawl is completely released from the preliminary-closed position as well as from the fully-closed stop position by means of the release driver arm rising from the blocking lever release arm.

5. Lock mechanism according to claim 4 , wherein the blocking lever when releasing the pawl is driven by a lock release lever connected to the door or hatch opening mechanism or by the rotary catch via the blocking lever driving arm.

6. Lock mechanism according to claim 4 , wherein the blocking lever when releasing the pawl is driven by the blocking lever driving arm via a recess in the catch.

7. Lock mechanism according to claim 1 , wherein the pawl and the blocking lever are both spring-preloaded in clockwise direction.

8. Lock mechanism according to claim 1 , wherein the rotary catch consists of two segments which form the lock bolt inlet, with one segment acting as preliminary-closed stop, and the second segment acting as fully-closed stop, where the stops are bevelled and provided with self-opening moments.

9. Motor vehicle showing a motor vehicle lock with a lock mechanism according to claim 1 for securing of a motor vehicle door.

10. Lock mechanism for a motor vehicle lock comprising a rotary catch, a pawl for positive locking the catch in a stop position, a blocking lever for blocking the pawl when the pawl is in its preliminary stop position and in its fully-closed stop position, and a release lever that is activated to move the blocking lever from blocking the pawl in the preliminary-closed stop position and fully-closed stop position,
wherein the blocking lever is designed so that it can overtravel the pawl from both the preliminary-closed stop position and the fully-closed stop position when the release lever is activated, and
wherein the blocking lever has two lever arms which are arranged in opposite directions to a blocking lever rotation axis, wherein one lever arm acts as a blocking lever release arm with a pawl driver arm, and the other lever arm possesses a blocking arm with a blocking surface for the pawl.

11. Lock mechanism according to claim 10 , wherein the pawl has two lever arms, arranged in opposite directions to a pawl rotational axis, with a pawl detent arm with a detent surface and a blocking surface, and with a pawl driving arm.
