Abstract

A vehicle seat for attaching to a vehicle structure of a vehicle has a seat part and a backrest. The vehicle seat is movable in the longitudinal direction of the vehicle in relation to the vehicle structure and adjustable into a resting or lying seat position. In the event of a collision, the vehicle seat with the seat part is or can be pivoted upwards along an axis extending parallel to the vehicle transverse direction, with a front region facing away from the back rest. The backrest, at least in the resting or lying position, is or can be connected to the vehicle structure of a tensile force transmission element.

First claim

What is claimed is:

1. A vehicle seat for attaching to a vehicle structure of a vehicle, comprising:
a seat part;
a backrest and
a tensile force transmission element,
wherein
the vehicle seat is displaceable relative to the vehicle structure in a longitudinal direction of the vehicle and is adjustable into a resting or lying seat position,
in an event of a collision, the entire vehicle seat is pivotable about an axis running parallel to a transverse direction of the vehicle as the vehicle seat is moving in the longitudinal direction, with a front region of the seat part facing away from the backrest moving upward, and
the tensile force transmission element is connectable between the backrest in a region of the backrest below a headrest and the vehicle structure located longitudinally behind the backrest when the vehicle seat is at least in the resting or lying position.

2. The vehicle seat according to claim 1 , wherein
the tensile force transmission element is attachable to the backrest in an upper half thereof.

3. The vehicle seat according to claim 1 , wherein
the tensile force transmission element is attachable to the backrest in an upper third thereof.

4. The vehicle seat according to claim 1 , wherein
the tensile force transmission element is attachable to the backrest in an upper quarter thereof.

5. The vehicle according to claim 1 , wherein
an energy absorption device is provided in the connection between the vehicle structure and the backrest, said connection having the tensile force transmission element.

6. The vehicle according to claim 5 , wherein
the tensile force transmission element has the energy absorption device.

7. The vehicle seat according to claim 5 , wherein
the energy absorption device has at least one deformation element.

8. The vehicle seat according to claim 5 , wherein
the energy absorption device is a tensile force limiting device.

9. The vehicle seat according to claim 1 , further comprising:
a seat console with which the vehicle seat is attachable to the vehicle structure directly or via a longitudinal adjustment device having a longitudinally displaceable slide.

10. A vehicle comprising at least one vehicle seat according to claim 1 .

11. The vehicle according to claim 10 , wherein the vehicle is a motor vehicle.

12. The vehicle seat according to claim 1 , wherein
the tensile force transmission element comprises a tension rod or a tension proof cable.

13. The vehicle seat according to claim 1 , wherein
one end of the tensile force transmission element is attached to the vehicle structure at a vertical location below that of another end which attaches to an upper half of the backrest when the vehicle seat is in the resting or lying seat position.

14. The vehicle seat according to claim 1 , wherein
in an event of a head-on collision, the tensile force transmission element is configured to pivot in a clockwise direction about a transverse axis of the vehicle until extending horizontally, wherein the vehicle seat is pivoted out of the resting or lying position counterclockwise.

15. The vehicle seat according to claim 14 , wherein
upon extending horizontally, an energy absorption device of the tensile force transmission element stretches upon exceeding a defined maximum tensile force, wherein the vehicle seat displaces in a forward longitudinal direction of the vehicle.

16. The vehicle seat according to claim 15 , wherein
the stretching of the energy absorption device is configured to be linear.

17. The vehicle seat according to claim 15 , wherein
the stretching of the energy absorption device is configured to be non-linear.
