Abstract

The present invention relates to a vehicle seat having a seat part and a backrest, wherein the seat part and the backrest can be adjusted relative to one another by an adjustment mechanism, wherein a base plate which holds the adjustment mechanism is provided, wherein the base plate has at least two passage openings through which the base plate is connected to the seat part by fasteners, wherein one of the passage openings is in the form of an elongate hole.

First claim

The invention claimed is:

1. A vehicle seat comprising a seat part and a backrest, wherein the seat part and the backrest are adjustable relative to one another by an adjustment mechanism, a base plate receiving the adjustment mechanism is provided, the base plate has at least two passage openings through which the base plate is connected to the seat part by fasteners, one of the passage openings is configured as a slot, a link plate at a first end is fixedly fastened to the seat part by a front fastener of the fasteners, a second end of the link plate is aligned in an approximately horizontal direction and is fixedly connected to the seat part, and the link plate is configured to be plastically deformed in an event of a rear impact as a result of a limited adjustment movement such that the link plate is bent between the first end and the second end.

2. The vehicle seat as claimed in claim 1 , wherein two link plates are provided, the two link plates are fastened to the base plate at their opposing ends by the fasteners, the other ends of the link plates are arranged on top of one another centrally between the fasteners and are fastened to the base plate with a fastening pin in a second slot, and the second slot extends substantially parallel to a direction of travel.

3. The vehicle seat as claimed in claim 1 , wherein the second end of the link plate is welded or screwed to the seat part or positively suspended therein.

4. The vehicle seat as claimed in claim 1 , wherein the fasteners comprise screws.

5. The vehicle seat as claimed in claim 1 , wherein the passage openings are arranged adjacent to one another in an approximately horizontal plane, and the slot extends in the horizontal plane.

6. The vehicle seat as claimed in claim 5 , wherein the slot forms a through-bore of the front fastener viewed in a direction of travel.

7. The vehicle seat as claimed in claim 1 , wherein the link plate connects the front fastener to another fastener of the fasteners, a drive element is provided on a lower face of the base plate, and the drive element is configured to entrain the link plate upwardly or vertically relative to a plate plane of the base plate as a result of the limited adjustment movement such that the link plate is bent.

8. The vehicle seat as claimed in claim 7 , wherein the drive element comprises a ramp which forms an oblique plane relative to the plate plane of the base plate.

9. The vehicle seat as claimed in claim 7 , wherein the drive element forms an extension that is angled back at an angle from the plate plane of the base plate.

10. A vehicle seat comprising a seat part and a backrest, wherein the seat part and the backrest are adjustable relative to one another by an adjustment mechanism, a base plate receiving the adjustment mechanism is provided, the base plate has at least two passage openings through which the base plate is connected to the seat part by fasteners, one of the passage openings is configured as a slot, a link plate at a first end is fastened to the seat part by a front fastener of the fasteners, a second end of the link plate is aligned in an approximately horizontal direction and is connected to the seat part, and the link plate is configured to be plastically deformed in an event of a rear impact as a result of a limited adjustment movement such that the link plate is bent between the first end and the second end;
wherein two link plates are provided, the two link plates are fastened to the base plate at their opposing ends by the fasteners, the other ends of the link plates are arranged on top of one another centrally between the fasteners and are fastened to the base plate with a fastening pin in a second slot, and the second slot extends substantially parallel to a direction of travel.

11. A vehicle seat comprising a seat part and a backrest, wherein the seat part and the backrest are adjustable relative to one another by an adjustment mechanism, a base plate receiving the adjustment mechanism is provided, the base plate has at least two passage openings through which the base plate is connected to the seat part by fasteners, one of the passage openings is configured as a slot, a link plate at a first end is fastened to the seat part by a front fastener of the fasteners, a second end of the link plate is aligned in an approximately horizontal direction and is connected to the seat part, and the link plate is configured to be plastically deformed in an event of a rear impact as a result of a limited adjustment movement such that the link plate is bent between the first end and the second end;
wherein the fasteners comprise screws.

12. The vehicle seat as claimed in claim 11 , wherein two link plates are provided, the two link plates are fastened to the base plate at their opposing ends by the fasteners, the other ends of the link plates are arranged on top of one another centrally between the fasteners and are fastened to the base plate with a fastening pin in a second slot, and the second slot extends substantially parallel to a direction of travel.

13. The vehicle seat as claimed in claim 11 , wherein the second end of the link plate is welded or screwed to the seat part or positively suspended therein.

14. The vehicle seat as claimed in claim 11 , wherein the passage openings are arranged adjacent to one another in an approximately horizontal plane, and the slot extends in the horizontal plane.

15. The vehicle seat as claimed in claim 14 , wherein the slot forms a through-bore of the front fastener viewed in a direction of travel.

16. The vehicle seat as claimed in claim 11 , wherein the link plate connects the front fastener to another fastener of the fasteners, a drive element is provided on a lower face of the base plate, and the drive element is configured to entrain the link plate upwardly or vertically relative to a plate plane of the base plate as a result of the limited adjustment movement such that the link plate is bent.

17. The vehicle seat as claimed in claim 16 , wherein the drive element comprises a ramp which forms an oblique plane relative to the plate plane of the base plate.

18. The vehicle seat as claimed in claim 16 , wherein the drive element forms an extension that is angled back at an angle from the plate plane of the base plate.
