Abstract

The invention concerns a locking mechanism provided and adapted to interact with at least one locking element to establish a locking between the locking mechanism and the locking element, wherein the locking mechanism comprises a first locking pawl and a second locking pawl which are rotatable independently of each other about a first rotary axis, wherein the first locking pawl is provided and adapted to interact with a first locking element and wherein the second locking pawl is provided and adapted to interact with a second locking element, wherein a secured locking is present when the first locking element is locked to the first locking pawl and the second locking element is locked to the second locking pawl.

First claim

What is claimed is:

1 . A locking mechanism provided and adapted to interact with at least one locking element to establish a locking between the locking mechanism and the locking element,
wherein the locking mechanism comprises a first locking pawl and a second locking pawl which are rotatable independently of each other about a first rotary axis, wherein the first locking pawl is provided and adapted to interact with a first locking element and wherein the second locking pawl is provided and adapted to interact with a second locking element, wherein a secured locking is present when the first locking element is locked to the first locking pawl and the second locking element is locked to the second locking pawl.

2 . The locking mechanism according to claim 1 ,
wherein the locking mechanism comprises a first safety pawl and a second safety pawl which are synchronously rotatable about a second rotary axis, the first safety pawl being provided and adapted to interact with the first locking pawl, and the second safety pawl being provided and adapted to interact with the second locking pawl, such that the locking pawls are held in a locked or unlocked position.

3 . The locking mechanism according to claim 1 ,
wherein a non-secured locking is present if at most one locking element is locked with the corresponding locking pawl.

4 . The locking mechanism according to claim 2 ,
wherein each of the locking pawls is movable from the unlocked position to the locked position of the locking pawl with the corresponding locking element by a rotation in a first direction of rotation about the first rotary axis, the rotation of the locking pawl being caused by bringing the locking pawl and the locking element into contact with and towards each other.

5 . The locking mechanism according to claim 2 ,
wherein in the unlocked position, the safety pawl is connected to a first section of the corresponding locking pawl and, in the locked position, the safety pawl is connected to a second section of the corresponding locking pawl, the respective safety pawl being displaceable from the first section into the second section by rotation in a first direction of rotation.

6 . The locking mechanism according to claim 4 ,
wherein for returning the locked position into the unlocked position, a Bowden cable element is provided which is connected to the second rotary axis in such a way that actuation of the Bowden cable element can cause the safety pawls to rotate in a second direction of rotation which is opposite to the first direction of rotation.

7 . The locking mechanism according to claim 1 ,
wherein the first rotary axis is acted upon by a first spring force and the locking pawls are each acted upon by a spring force, the first spring force being acted upon by a first torsion spring and each locking pawl being acted upon by a tension spring.

8 . The locking mechanism of claim 4 ,
wherein a first comfort pawl and a second safety pawl are provided which are designed and configured to compensate for tolerances between the respective pawls and locking pawls so that the locking pawls can be fully rotated into locked position.

9 . The locking mechanism according to claim 8 ,
wherein the comfort pawls are each arranged at an angle to the safety pawls and are connected to the second rotary axis in such a way that a slight rotation relative to the second rotary axis is possible, wherein the comfort pawls are subjected to a spring force.

10 . The locking mechanism according to claim 1 ,
wherein the first rotary axis and the second rotary axis are spaced apart and parallel to each other.

11 . The locking mechanism according to claim 1 ,
wherein the locking pawls are arranged at a first distance from each other in a width direction and the safety pawls are arranged at a second distance from each other in the width direction.

12 . The locking mechanism according to claim 2 ,
wherein a non-secured locking is present if at most one locking element is locked with the corresponding locking pawl.

13 . The locking mechanism according to claim 5 ,
wherein for returning the locked position into the unlocked position, a Bowden cable element is provided which is connected to the second rotary axis in such a way that actuation of the Bowden cable element can cause the safety pawls to rotate in a second direction of rotation which is opposite to the first direction of rotation.

14 . The locking mechanism according to claim 2 ,
wherein the first rotary axis is acted upon by a first spring force and the locking pawls are each acted upon by a spring force, the first spring force being acted upon by a first torsion spring and each locking pawl being acted upon by a tension spring.

15 . The locking mechanism according to claim 3 ,
wherein the first rotary axis is acted upon by a first spring force and the locking pawls are each acted upon by a spring force, the first spring force being acted upon by a first torsion spring and each locking pawl being acted upon by a tension spring.

16 . The locking mechanism according to claim 4 ,
wherein the first rotary axis is acted upon by a first spring force and the locking pawls are each acted upon by a spring force, the first spring force being acted upon by a first torsion spring and each locking pawl being acted upon by a tension spring.

17 . The locking mechanism according to claim 5 ,
wherein the first rotary axis is acted upon by a first spring force and the locking pawls are each acted upon by a spring force, the first spring force being acted upon by a first torsion spring and each locking pawl being acted upon by a tension spring.

18 . The locking mechanism according to claim 6 ,
wherein the first rotary axis is acted upon by a first spring force and the locking pawls are each acted upon by a spring force, the first spring force being acted upon by a first torsion spring and each locking pawl being acted upon by a tension spring.

19 . The locking mechanism according to claim 2 ,
wherein the first rotary axis and the second rotary axis are spaced apart and parallel to each other.

20 . The locking mechanism according to claim 3 ,
wherein the first rotary axis and the second rotary axis are spaced apart and parallel to each other.
