Abstract

A vehicle seat for a motor vehicle has a backrest which is mounted, so as to be pivotable about a pivot axis, on a fitting that is located on the associated seat side and is connected to a seat side part of a seat part, the seat side part being located on the seat side, via a deformation device. The deformation device has a bolt that is accommodated in a deformation element of the fitting and can be displaced along a deformation guide in the event of an accident-induced overload. A sliding element is located between the fitting and the seat side part.

First claim

1 .- 8 . (canceled)

9 . A vehicle seat for a motor vehicle, comprising:
a backrest; a seat side part of a seat part, the seat side part being located on a side of the vehicle seat; a fitting connected to the seat side part on the side of the vehicle seat; a deformation device via which the backrest is mounted on the fitting so as to be pivotable about a pivot axis, wherein the deformation device comprises a bolt which is received in a deformation element on the fitting and is displaceable along a deformation guide in an event of an accident-induced overload; and a sliding element arranged between the fitting and the seat side part.

10 . The vehicle seat according to claim 9 , wherein
the sliding element is arranged between the deformation element, which is fastened to the fitting, and the seat side part.

11 . The vehicle seat according to claim 10 , wherein
on that side of the fitting facing away from the sliding element, a further sliding element is arranged between said fitting and a bolt head of the bolt.

12 . The vehicle seat according to claim 9 , further comprising:
a bushing by which the bolt head is spaced apart from the seat side part, wherein on the bushing the sliding element is arranged on an outer circumferential side.

13 . The vehicle seat according to claim 9 , wherein
the sliding element is formed as a plastic element or a metal element from a friction-reducing material or with a friction-reducing coating.

14 . The vehicle seat according to claim 9 , wherein
the sliding element has a friction-reducing surface.

15 . The vehicle seat according to claim 14 , wherein
the sliding element has a corrugated contour to facilitate the friction reducing surface.

16 . The vehicle seat according to claim 12 , wherein
the deformation guide of the deformation element has a bushing opening which is adapted to an outer cross section of the bushing and which is adjoined by a deflection opening, wherein respective absorption elevations are provided between the bushing opening and the deflection opening.
