Process for precessing an infant seat body used in vehicles and the seat body obtained

Abstract

A process for molding an infant safety seat body for vehicles includes the steps of forming a contoured seat frame, disposing the contoured seat frame in a mold having the shape of the infant safety seat body, pouring foam into said mold and polymerizing the foam to form a cushion substrate, and stripping the foam from the mold.

What is claimed is:  
     
         1 . A process for preparing an infant safety seat body used in vehicles, comprising the steps of: 
 forming a contoured seat frame;    disposing the contoured seat frame in a mold having the shape of the infant safety seat body;    pouring foam into said mold and polymerizing the foam to form a cushion substrate; and    striping the foam from the mold.    
     
     
         2 . The process according to  claim 1 , wherein said step of forming said contoured seat frame is carried out by the steps of: 
 injection molding a synthetic resin into a porous plate; and    folding and bonding said porous plate so as to form said contoured seat frame.    
     
     
         3 . The process according to  claim 1 , wherein said step of forming said contoured seat frame is carried out by welding a metal web.  
     
     
         4 . An infant safety seat body used in vehicles, comprising: 
 a contoured seat frame; and    a cushion substrate integrally molded with said seat frame by polymerizing a foam material.    
     
     
         5 . The infant safety seat body according to  claim 4 , wherein said contoured seat frame is formed by folding and bonding a porous plate so as to form said contoured seat frame.  
     
     
         6 . The infant safety seat body according to  claim 5 , wherein said porous plate is formed by injection molding a synthetic resin.  
     
     
         7 . The infant safety seat body according to  claim 4 , wherein said contoured seat frame is formed by welding a metal web.
