Abstract

A method for producing vehicle seat components involves working a semifinished blank in a cutting manner. The method can be carried out easily and at low cost and makes it possible to produce components that require little reworking and also provides a vehicle seat component that is both suitable for reducing crash energies by deformation and has an adequate wear resistance. The method includes local heating of the semifinished blank in the region of an intended cutting line of the vehicle seat components to be cut out and cutting out the vehicle seat components from the semifinished blank along the cutting line during or shortly after the heating.

First claim

The invention claimed is:

1. A method for producing vehicle seat components through the working of a semifinished blank in a cutting manner, the method comprising:
locally heating the semifinished blank in the area of an intended cutting line of the vehicle seat components to be cut out;
cutting out the vehicle seat components from the semifinished blank with a cutting device along the cutting line during or after the heating of the semifinished blank to create an entire edge area of the vehicle seat components, wherein the edge area comprises an entire peripheral surface of the vehicle seat components and openings in the vehicle seat components, wherein the semifinished blank is locally heated with the cutting device while the semifinished blank remains in the cutting device, and
wherein the vehicle seat components each comprise a base section delimited by the edge area;
partially heating the vehicle seat components with the cutting device while the vehicle seat components remain in the cutting device after having been cut from the semifinished blank such that all of and only the edge areas of the vehicle seat components are directly heated after the vehicle seat components have been cut; and
cooling the vehicle seat components through heat conduction into the cutting device after the cutting out of the vehicle seat components,
wherein the local heating of the semifinished blank and the partial heating of the vehicle seat components is achieved through the effect of heat radiation,
wherein all of the edge area of at least one of the vehicle seat components is hardened through the effect of heat radiation during the partial heating of the vehicle seat components.

2. The method according to claim 1 , wherein the heating of the vehicle seat components takes place through a deflection of directed radiation taking place by a beam filter, a mirror and/or beam diffraction.

3. The method according to claim 1 , wherein the vehicle seat components are configured to be components for a seat adjuster of a motor vehicle seat.

4. The method according to claim 1 , wherein the cutting device comprising a clamping device that cools the vehicle seat components through the heat conduction into the cutting device.

5. The method according to claim 1 , wherein different areas of the edge areas of the vehicle seat components have different material properties as a result of different beatings.

6. The method according to claim 1 , wherein the vehicle seat components are cut out from the semifinished blank along the cutting line during the local heating of the semifinished blank in the area of the cutting line.

7. The method according to claim 1 , wherein the cutting device is configured to cool the vehicle seat components in a controlled manner.
