Abstract

A vehicle seat ( 1 ) includes a structural part ( 3 ) which has a lock connection plate ( 60 ) and a locking unit ( 10 ) which is fixed to the lock connection plate ( 60 ). The locking unit ( 10 ) has at least one bearing bolt ( 51 ) with a passage opening ( 55 ). The lock connection plate ( 60 ) also comprises at least one mating contour ( 62 ) which projects into the passage opening ( 55 ) in the at least one bearing bolt ( 51 ).

First claim

The invention claimed is:

1. A vehicle seat comprising:
a structural part, the structural part comprising a backrest, the backrest comprising a lock connection plate;
a seat cushion; and
a locking unit comprising a locking unit housing, the locking unit housing being non-movably fixed to the lock connection plate, wherein the locking unit comprises at least one housing opening and at least one bearing bolt with a bearing bolt through-opening and the lock connection plate comprises at least one mating contour which projects into the through-opening of the at least one bearing bolt, the bearing bolt being non-rotatably connected to the locking unit housing, at least a portion of the at least one bearing bolt being arranged in the at least one housing opening, the locking unit comprising a locked state and an unlocked state, the backrest being fixed relative to the seat cushion in the locked state, the backrest being pivotable relative to the seat cushion in the unlocked state.

2. The vehicle seat as claimed in claim 1 , wherein the through-opening has a first axial portion with a first internal diameter and a second axial portion with a second internal diameter, wherein the second internal diameter is larger than the first internal diameter.

3. The vehicle seat as claimed in claim 2 , wherein the second axial portion faces the lock connection plate.

4. The vehicle seat as claimed in claim 3 , wherein an external diameter of the mating contour corresponds to the second internal diameter.

5. The vehicle seat as claimed in claim 3 , wherein a length of the mating contour in the axial direction corresponds to a length of the second axial portion.

6. The vehicle seat as claimed in claim 3 , wherein an internal diameter of the mating contour corresponds to the first internal diameter.

7. The vehicle seat as claimed in claim 1 , wherein the mating contour is configured as a collar.

8. The vehicle seat as claimed in claim 1 , wherein the through-opening is penetrated by a fastening means.

9. The vehicle seat as claimed in claim 8 , wherein the fastening means is configured as a screw with a head and a shank.

10. The vehicle seat as claimed in claim 9 , wherein the mating contour has an internal thread, the screw being screwed therein.

11. The vehicle seat as claimed in claim 9 , wherein a nut is provided on the side of the lock connection plate remote from the locking unit, the screw being screwed therein.

12. The vehicle seat as claimed in claim 8 , wherein the fastening means is configured as a rivet.

13. The vehicle seat as claimed in claim 1 , wherein the structural part of the vehicle seat is a backrest.

14. The vehicle seat as claimed in claim 1 , wherein a rotary latch is pivotably mounted on the bearing bolt.

15. The vehicle seat as claimed in claim 1 , wherein the locking unit has at least one further bearing bolt, at least one securing element being pivotably mounted thereon.

16. The vehicle seat as claimed in claim 1 , wherein the locking unit comprises a rotary latch and a latching pawl, the rotary latch being in contact with the latching pawl with the locking unit in the locked state, the rotary latch being at a spaced location from the latching pawl with the locking unit in the unlocked state, one of the rotary latch and the latching pawl being rotatably mounted on the bearing bolt, wherein the one of the rotary latch and the latching pawl is rotatable relative to the bearing bolt.

17. The vehicle seat as claimed in claim 16 , wherein the locking unit comprises a further bearing bolt, wherein another one of the rotary latch and the latching pawl being rotatably mounted on the further bearing bolt.

18. The vehicle seat as claimed in claim 17 , further comprising:
a first fastener, the lock connection plate comprising a first lock connection plate through opening and a second lock connection plate through opening, the first locking connection plate through opening being aligned with the bearing bolt through opening to define a first through opening, at least a portion of the first fastener being arranged in the first through opening;
a second fastener, wherein the locking unit housing has a second housing opening, at least a portion of the further bearing bolt being arranged in the second housing opening, the further bearing bolt comprising a further bearing bolt through opening, the second lock connection plate through opening being aligned with the further bearing bolt through opening to define a second through opening, at least a portion of the second fastener being arranged in the second through opening.

19. A vehicle seat comprising:
a backrest comprising a lock connection plate, the lock connection plate comprising a lock connection plate through opening;
a seat cushion;
a fastener; and
a locking unit comprising a locking unit housing, the locking unit housing being non-rotatably fixed to the lock connection plate, wherein the locking unit comprises at least one housing opening and at least one bearing bolt with a bearing bolt through-opening and the lock connection plate comprises at least one mating contour which projects into the through-opening of the at least one bearing bolt, wherein the bearing bolt is non-rotatably connected to the locking unit housing, at least a portion of the at least one bearing bolt being arranged in the at least one housing opening, the lock connection plate through opening being arranged opposite the bearing bolt through-opening, at least a portion of the fastener being arranged in the locking connection plate through-opening and the bearing bolt through-opening, the locking unit comprising a locked state and an unlocked state, the backrest being fixed relative to the seat cushion in the locked state, the backrest being pivotable relative to the seat cushion in the unlocked state.

20. A vehicle seat comprising:
a backrest comprising a lock connection plate, the lock connection plate comprising a lock connection plate through opening;
a seat cushion;
a fastener; and
a locking unit comprising a locking unit housing and a rotary latch, the locking unit housing being non-rotatably fixed to the lock connection plate, the locking unit being in direct contact with the lock connection plate, wherein the locking unit comprises at least one housing opening and at least one bearing bolt with a bearing bolt through-opening and the lock connection plate comprises at least one mating contour which projects into the through-opening of the at least one bearing bolt, the rotary latch being rotatably connected to the at least one bearing bolt, wherein the rotary latch is rotatable relative to the at least one bearing bolt and the bearing bolt is non-rotatably connected to the locking unit housing, at least a portion of the at least one bearing bolt being arranged in the at least one housing opening, the lock connection plate through opening being arranged opposite the bearing bolt through-opening, at least a portion of fastener being arranged in the locking connection plate through-opening and the bearing bolt through-opening, the locking unit comprising a locked state and an unlocked state, the backrest being fixed relative to the seat cushion in the locked state, the backrest being pivotable relative to the seat cushion in the unlocked state.
