Abstract

Embodiments described herein relate to an end part for a cross member for a vehicle seat, a cross member for a vehicle seat comprising at least one end part, and a vehicle seat comprising at least one such cross member. The end part has a first portion with an impact receiving surface adapted to receive an impact during a side collision. The cross member has a longitudinal center line. A center point of the impact receiving surface is offset with respect to the longitudinal center line so as to bend the cross member in a predetermined direction during the side collision. The present invention provides for a simple way to modify a cross member, or to provide a cross member with additional functionality and increased safety properties.

First claim

What is claimed is:

1. An end part for a cross member for a vehicle seat, comprising:
a first portion having an impact receiving surface adapted to receive an impact and transmit it to said cross member,
wherein said impact receiving surface transcends via an angled surface towards a second portion, wherein said angled surface is angled with respect to said impact receiving surface,
said cross member having a longitudinal center line,
wherein a center point of said impact receiving surface is offset with respect to said longitudinal center line so as to bend said cross member in a predetermined direction during said impact.

2. The end part according to claim 1 , wherein said end part comprises a second portion adapted to be connected to said cross member.

3. The end part according to claim 2 , wherein said second portion has a cross section with a diameter and a center point, said center point of said second portion is adapted to be aligned with said longitudinal center line of said cross member after assembly therewith.

4. The end part according to claim 1 , wherein a portion of said end part is adapted to be inserted into a cavity of said cross member.

5. The end part of claim 1 , wherein said impact receiving surface is adapted to redirect an impact force received along a first direction, said first direction being aligned with said longitudinal center line of said cross member so as to bend said cross member in said predetermined direction during said impact.

6. The end part according to claim 1 , wherein said center point is offset with respect to said longitudinal center line with a distance of from 2-80 mm, preferably 3-60 mm, more preferably 5-50 mm.

7. The end part according to claim 1 , wherein said impact receiving surface of said first portion has an area of between 100 mm 2 and 800 mm 2 .

8. The end part according to claim 1 , wherein said impact receiving surface forms a plane, wherein said plane is arranged at an angle of from 90-60 degrees with respect to the longitudinal center line (L 1 ) of the cross member.

9. The end part according to claim 1 , wherein at least a portion of said end part is configured to rotate a limited amount of degrees, or to rotate freely.

10. The end part according to claim 1 , wherein said end part forms a part of a seat position adjustment system.

11. A cross member for a vehicle seat, comprising at least one end part according claim 1 .

12. The cross member according to claim 11 , wherein said at least one end part is a separate piece of material with respect to said cross member, or an integrated piece of material with respect to said cross member.

13. A vehicle seat comprising at least one cross member and at least one end part, wherein the at least one end part comprises:
a first portion having an impact receiving surface adapted to receive an impact and transmit it to said cross member,
said cross member having a longitudinal center line,
wherein a center point of said impact receiving surface is offset with respect to said longitudinal center line so as to bend said cross member in a predetermined direction during said impact,
wherein said vehicle seat comprises a first and a second slide portion along which the position of said vehicle seat is adapted to be displaced and which defines a periphery limit,
wherein said at least one end part extends outside of said periphery limit defined by said first and second slide portions.

14. An end part for a cross member for a vehicle seat, comprising:
a first portion having an impact receiving surface adapted to receive an impact and transmit it to said cross member, and
a second portion adapted to be connected to said cross member,
said cross member having a longitudinal center line,
wherein said second portion has a cross section with a diameter and a center point, said center point of said second portion being adapted to be aligned with said longitudinal center line of said cross member after assembly therewith,
wherein a center point of said impact receiving surface is offset with respect to said center point of said second portion so as to bend said cross member in a predetermined direction during said impact.
