Abstract

The present invention relates to a component { 1, 2, 3, 4, 6 ) within the interior of a vehicle. Specifically, the present invention relates to a part of a seat-structure. The present invention further relates to a process to produce a component { 1, 2, 3, 4, 6 ) w{umlaut over (ι)}thin the interior of a vehicle.

First claim

The invention claimed is:

1. A vehicle-interior-component selected from a side member of a back of a vehicle seat and, a side member which is set under the vehicle seat, wherein the component is made from metal, which is formed and then treated entirely and/or locally in a treated area to modify its material strength, wherein the treated area is an area where a recliner is attached to the side member of the back of the vehicle seat or an area where the recliner is attached to the side member set under the vehicle seat, wherein the treated area of the component includes a front section of the side member of the back of the vehicle seat and/or of the side member set under the vehicle seat.

2. The vehicle-interior-component according to claim 1 , wherein the material strength is increased entirely or locally.

3. The vehicle-interior-component according to claim 1 , wherein the component is made from boron steel.

4. The vehicle-interior-component according to claim 1 , wherein the material strength is increased and the increased material strength for the treated area exhibits a yield strength, R p , of from 1000 to 1200 MPa for and/or a fracture strength, R m , of from 1300 to 1500 MPA.

5. The vehicle-interior-component according to claim 1 , wherein the component is treated locally and the material strength for the untreated area exhibits a yield strength, R p , of from 600 to 800 MPa and/or a fracture strength, R m , of from 900 to 1100 MPA.

6. The vehicle-interior-component according to claim 1 , wherein the seat comprises one or more ball races and a latching area wherein the ball races and/or the latching area are modified in their material strength in the upper rail and/or the under rail.

7. A vehicle-interior-component selected from a side member of a back of a vehicle seat and a side member which a set under the vehicle seat, wherein the component is made from metal, which is formed and then treated entirely and/or locally in a treated area to modify its material strength, wherein the treated are is an area where a recliner is attached to the side member of the back of the vehicle seat or an area where the recliner is attached to the side member set under the vehicle seat, and wherein a center area of the side member of the back of the vehicle seat and/or the side member set under the vehicle seat is left in a soft and ductile condition.

8. The vehicle-interior-component according to claim 7 , wherein the material strength is increased entirely or locally.

9. The vehicle-interior-component according to claim 7 , wherein the component is made from boron steel.

10. The vehicle-interior-component according to claim 7 , wherein the material strength is increased and the increased material strength for the treated area exhibits a yield strength, R p of from 1000 to 1200 MPa for and/or a fracture strength, R m , of from 1300 to 1500 MPA.

11. The vehicle-interior-component according to claim 7 , wherein the component is treated locally and the material strength for the untreated area exhibits a yield strength, R p , of from 600 to 800 MPa and/or a fracture strength, R m , of from 900 to 1100 MPA.

12. The vehicle-interior-component according to claim 7 , wherein the seat comprises one or more ball races and a latching area wherein the ball races and/or the latching area are modified in their material strength in the upper rail and/or the under rail.
