Method for manufacturing a structural component for a motor vehicle

Abstract

A method for manufacturing a component of a vehicle structure or vehicle seat structure is provided that includes, but is not limited to pressing a starting material through a die in order to produce an extruded product, separating a section from the extruded product, and forming the separated section into the component. A varying wall thickness of the separated section is produced during the pressing through the die.

1 . A method for manufacturing a component of a motor vehicle structure, comprising the steps of:
 pressing a starting material through a die in order to produce an extruded product;   separating a section from the extruded product to produce a separated section comprising a varying wall thickness transverse to an extruding direction (y) prior to forming an produced during the pressing the starting material through the die; and   forming the separated section into the component.   
     
     
         2 . The method of  claim 1 , wherein the component is a vehicle seat structure for a motor vehicle seat. 
     
     
         3 . The method according to  claim 1 , wherein at least one region of the separated section that is subjected to a higher load comprises has a greater wall thickness than at least one other region that is subjected to a lower load. 
     
     
         4 . The method according to  claim 3 , wherein the component is a crossbeam of a frame-like backrest structure and the separated section comprises the greater wall thickness in a region of a headrest receptacle. 
     
     
         5 . The method according to  claim 3 , wherein the component is a seat shell and the separated section comprises the greater wall thickness in a region of a bearing point. 
     
     
         6 . The method according to  claim 1 , wherein the starting material comprises magnesium. 
     
     
         7 . The method according to  claim 1 , wherein the starting material comprises aluminum. 
     
     
         8 . The method according to  claim 1 , wherein the starting material comprises a magnesium alloy. 
     
     
         9 . The method according to  claim 1 , wherein the starting material comprises an aluminum alloy. 
     
     
         10 . The method according to  claim 1 , wherein the extruded product is produced by impact extrusion. 
     
     
         11 . The method according to  claim 1 , wherein the separated section is formed into the component with a compressive deformation. 
     
     
         12 . The method according to  claim 11 , wherein the compressive deformation is an open-die forging. 
     
     
         13 . The method according to  claim 11 , wherein the compressive deformation is a closed-die forging. 
     
     
         14 . The method according to  claim 11 , wherein the separated section is formed into the component by hot forming. 
     
     
         15 . The method according to  claim 14 , wherein the hot forming utilizes a heating process. 
     
     
         16 . The method according to  claim 1 , wherein the extruded product has a smaller width than a finished component. 
     
     
         17 . The method according to  claim 1 , wherein the extruded product is realized in a sheet-like fashion.
