Seat cushion panel and method of manufacturing the same

Abstract

The seat cushion panel of a vehicle is manufactured using a magnesium alloy. The seat cushion panel includes a housing panel having a reinforcing means molded thereto.

1 . A seat cushion panel of a vehicle manufactured using a magnesium alloy comprising a housing panel, wherein a part of the housing panel, which is vulnerable to concentrated stress, is provided with a reinforcing means integrally molded thereto for the purpose of releasing stress.  
   
   
       2 . The seat cushion panel of a vehicle manufactured using a magnesium alloy according to  claim 1 , wherein said reinforcing means comprises: 
 a round reinforcing means positioned at the curved portion of said housing panel; and    a spring mounting element with closed supportive ends positioned at a S spring mounting portion.    
   
   
       3 . The seat cushion panel of a vehicle manufactured using a magnesium alloy according to  claim 1 , wherein a switch bracket employed in a motor-driven seat is further attached to said housing panel by means of a clip-inserting structure.  
   
   
       4 . A method of manufacturing a seat cushion panel of a vehicle manufactured using a magnesium alloy, wherein a casting gate is installed in the center of a mold so that a molten metal, in the course of molding via die casting, is dispersed at various directions and flowed into said mold, wherein said molten metal is flowed into said mold at the rate of about 4.0-5.0 m/sec under the virtual pressure of about 600 bar, wherein the diameter of the sleeve is about 100 mm.  
   
   
       5 . A seat cushion panel of a vehicle, comprising: 
 a seat cushion housing panel manufactured using a magnesium alloy and provided with a reinforcing mechanism integrally molded thereto for the purpose of releasing stress.    
   
   
       6 . The seat cushion panel according to  claim 5 , wherein said reinforcing mechanism comprises: 
 a round reinforcing mechanism is positioned at the curved portion of said housing panel; and    a spring mounting element with closed supportive ends at a spring mounting portion.    
   
   
       7 . The eat cushion panel according to  claim 5 , wherein a switch bracket employed in a motor-driven seat is further attached to said housing panel by means of a clip-inserting structure.
