A method is provided for producing a support structure, preferably a support structure for a vehicle seat having at least one seat shell for the seat part and/or the backrest of the vehicle seat, having the following method steps of producing a metal semi-finished product and reshaping it into an essentially flat plate, detaching a plate part from the plate, and deforming the plate part, the production of the metal semi-finished product being performed by extrusion. The semi-finished product may be already formed into a flat plate by the extrusion or the extrusion is performed with production of a curved plate, which is subsequently reshaped into a flat plate.

1. A method for producing a support structure for a seat bottom of a vehicle seat, comprising: extruding a metal semi-finished product through a die having a curved outlet opening of a predetermined thickness to produce a curved plate having a thickness of the predetermined thickness;roll forming the curved plate into an essentially flat plate;stamping a plate part out of the essentially flat plate; anddeforming by deep drawing the plate part into a seat shell, the seat shell forming the support structure for the seat bottom of the vehicle seat. 2. The method according to claim 1, wherein the curved plate is produced with an open cross-section. 3. The method according to claim 2, wherein the open cross-section is a U-shaped cross-section. 4. The method according to claim 1, wherein the curved plate is produced with a closed cross-section that is opened in a subsequent step of the method in order to obtain the curved plate having an open cross-section. 5. The method according to claim 1, wherein the predetermined thickness is at most approximately 100% greater than a target plate thickness (ds) of a completed plate part. 6. The method according to claim 1, wherein the predetermined thickness is at most approximately 50% greater than a target plate thickness (ds) of a completed plate part. 7. The method according to claim 1, wherein the predetermined thickness corresponds to a target plate thickness (ds) of a completed plate part. 8. The method according to claim 1, wherein the roll forming reduces a thickness of the essentially flat plate to a target plate thickness for a completed plate part. 9. The method according to Claim 1, wherein the deep drawing is a hot forming. 10. The method according to claim 9, wherein the hot forming is conducted with residual heat from the extrusion. 11. The method according to claim 1, wherein the metal semi-finished product is produced from a material having a lower density than steel. 12. The method according to claim 1, wherein the metal semi-finished product is produced from a material having a lower density than steel. 13. The method according to claim 1, wherein the metal semi-finished product is produced from magnesium or a magnesium alloy. 14. The method according to claim 1, wherein the metal semi-finished product is produced from aluminum alloy. 15. The method according to claim 1, further comprising the step of fastening the seat shell on an component adjacent to the support structure. 16. The method according to claim 15, further comprising the steps of: producing at least one hole within the adjacent component;situating the seat shell on the adjacent component;heating the seat shell in an area of the at least one hole to a temperature that is between a first melting temperature of the seat shell and a second melting temperature of the adjacent component.
