Abstract

A vehicle seat ( 1 ) with a seat segment ( 14 ) which includes a first seat area ( 11 ) with a first backrest ( 21 ) that can be pivoted about a pivot axis (A) running in a transverse direction (y) and a second seat area ( 12 ) with a second backrest ( 22 ) that can be pivoted about the pivot axis (A). The second backrest ( 22 ) is equipped with a locking device ( 9 ) which interacts with a locking bracket ( 8 ) provided on the first backrest ( 21 ). The locking device ( 9 ) includes at least one axis pin ( 92 ) with a longitudinal axis ( 94 ) that is inclined relative to the transverse direction (y).

First claim

The invention claimed is:

1. A vehicle seat comprising a seat segment which comprises:
a first seating space having a first backrest which can be pivoted about a pivot axis which extends in the transverse direction and
a second seating space having a second backrest which can be pivoted about the pivot axis;
a locking device arranged on the second backrest; and
a curved locking member provided on the first backrest, wherein the locking device comprises at least one axial pin with a longitudinal axis that extends in an inclined manner relative to the transverse direction, wherein the locking device comprises a rotary latch which is pivotably supported about the axial pin.

2. The vehicle seat as claimed in claim 1 , wherein the longitudinal axis defines with the transverse direction an inclination angle of from 5° to 15°.

3. The vehicle seat as claimed in claim 2 , wherein the longitudinal axis defines with the transverse direction an inclination angle of 10°.

4. The vehicle seat as claimed in claim 1 , wherein the at least one axial pin is not parallel and not perpendicular to the transverse direction.

5. The vehicle seat as claimed in claim 1 , wherein the curved locking member comprises a locking region around which the rotary latch engages when the locking device is locked to the curved locking member.

6. The vehicle seat as claimed in claim 5 , wherein the locking region is constructed to be substantially linear and to extend along a curved member axis.

7. The vehicle seat as claimed in claim 6 , wherein the curved member axis extends in an inclined manner relative to the transverse direction.

8. The vehicle seat as claimed in claim 6 , wherein the curved member axis defines with the transverse direction an inclination angle of from 5° to 15°.

9. The vehicle seat as claimed in claim 8 , wherein the curved member axis defines with the transverse direction an inclination angle of 10°.

10. The vehicle seat as claimed in claim 6 , wherein, when the locking device is locked to the curved locking member, the curved member axis extends parallel with the longitudinal axis of the axial pin.

11. The vehicle seat as claimed in claim 1 , wherein the locking device comprises an additional axial pin about which at least one of a clamping cam and a catch cam which serves to secure the rotary latch when the locking device is locked is pivotably supported.

12. The vehicle seat as claimed in claim 11 , wherein the additional axial pin has another longitudinal axis which extends parallel with the longitudinal axis of the axial pin, about which the rotary latch is pivotably supported.

13. A vehicle seat comprising a seat segment which comprises:
a first seating space having a first backrest which can be pivoted about a pivot axis which extends in the transverse direction; and
a second seating space having a second backrest which can be pivoted about the pivot axis, the second backrest comprising a substantially upright use position and a non-use position;
a locking device arranged on the second backrest; and
a curved locking member provided on the first backrest, wherein the locking device comprises at least one axial pin with a longitudinal axis, the longitudinal axis being substantially perpendicular to a vertical direction and inclined relative to the transverse direction and not perpendicular to a travel direction when the second backrest is in the substantially upright use position, the longitudinal axis being substantially perpendicular to the travel direction and inclined relative to the transverse direction and not perpendicular to the vertical direction when the second backrest is in the non-use position.

14. The vehicle seat as claimed in claim 13 , wherein the first backrest comprises a substantially upright first backrest use position and a first backrest non-use position, the longitudinal axis being substantially perpendicular to the vertical direction and inclined relative to the transverse direction and not perpendicular to the travel direction when the first backrest is in the substantially upright first backrest use position, the longitudinal axis being substantially perpendicular to the travel direction and inclined relative to the transverse direction and not perpendicular to the vertical direction when the first backrest is in the first backrest non-use position.

15. The vehicle seat as claimed in claim 13 , wherein the locking device comprises a rotary latch which is pivotably supported about the axial pin.

16. A vehicle seat comprising a seat segment which comprises:
a first seating space having a first backrest which can be pivoted about a pivot axis which extends in the transverse direction and
a second seating space having a second backrest which can be pivoted about the pivot axis;
a locking device arranged on the second backrest; and
a curved locking member provided on the first backrest, wherein the locking device comprises at least one axial pin with a longitudinal axis inclined relative to the transverse direction, wherein the longitudinal axis is not parallel to the transverse direction and the longitudinal axis is not perpendicular to the transverse direction.

17. The vehicle seat as claimed in claim 16 , wherein the second backrest comprises a substantially upright use position and a non-use position, the longitudinal axis being substantially perpendicular to a vertical direction and inclined relative to the transverse direction and not perpendicular to a travel direction when the second backrest is in the substantially upright use position, the longitudinal axis being substantially perpendicular to the travel direction and inclined relative to the transverse direction and not perpendicular to the vertical direction when the second backrest is in the non-use position.

18. The vehicle seat as claimed in claim 17 , wherein the first backrest comprises a substantially upright first backrest use position and a first backrest non-use position, the longitudinal axis being substantially perpendicular to the vertical direction and inclined relative to the transverse direction and not perpendicular to the travel direction when the first backrest is in the substantially upright first backrest use position, the longitudinal axis being substantially perpendicular to the travel direction and inclined relative to the transverse direction and not perpendicular to the vertical direction when the first backrest is in the first backrest non-use position.

19. The vehicle seat as claimed in claim 16 , wherein the locking device comprises a rotary latch which is pivotably supported about the axial pin.
