A foldable child booster seat

Abstract

A foldable child booster seat based on the origami and popup technique. The booster seat is light and easy to be folded flat into a compact form for storage and transport. The foldable booster seat, comprising: a plurality of rigid substrates, each rigid substrate is interconnected to another by one or more integrated hinges or flexible parts allowing the rigid substrate to fold either inward or outward when folding up; wherein when the foldable booster seat is folded flat, the rigid substrates are stacked together; and wherein when the foldable booster seat is folded up, the rigid substrates are arranged to form the shape of a chair or stool.

What is claimed is: 
     
         1 . A foldable booster seat, comprising:
 a plurality of rigid substrates, each rigid substrate is interconnected to another by one or more integrated hinges or flexible parts allowing the rigid substrate to fold either inward or outward when folding up;   wherein when the foldable booster seat is folded flat, the rigid substrates are stacked together; and   wherein when the foldable booster seat is folded up, the rigid substrates are arranged to form the shape of a chair or stool.   
     
     
         2 . The foldable booster seat of  claim 1 , wherein shapes and sizes of the rigid substrates and placements of the hinges or flexible parts are dictated by one or more sheet material cutout patterns. 
     
     
         3 . The foldable booster seat of  claim 1 , wherein each of the rigid substrates comprises two layers of fabric and a hard plastic member inserted in between the two layers of fabric. 
     
     
         4 . The foldable booster seat of  claim 1 , wherein each of the rigid substrates comprises two layers of fabric and a fiberglass member inserted in between the two layers of fabric. 
     
     
         5 . The foldable booster seat of  claim 1 , wherein each of the rigid substrates comprises two layers of fabric and a hard material member inserted in between the two layers of fabric. 
     
     
         6 . The foldable booster seat of  claim 1 , wherein each of the rigid substrates comprises a carbon fiber member. 
     
     
         7 . A foldable furniture, comprising:
 a plurality of rigid substrates, each rigid substrate is interconnected to another by one or more integrated hinges or flexible parts allowing the rigid substrate to fold either inward or outward when folding up;   wherein when the foldable booster seat is folded flat, the rigid substrates are stacked together; and   wherein when the foldable booster seat is folded up, the rigid substrates are arranged to form the shape of a chair or stool.   
     
     
         8 . The foldable furniture of  claim 7 , wherein shapes and sizes of the rigid substrates and placements of the hinges or flexible parts are dictated by one or more sheet material cutout patterns. 
     
     
         9 . The foldable furniture of  claim 7 , wherein each of the rigid substrates comprises two layers of fabric and a hard plastic member inserted in between the two layers of fabric. 
     
     
         10 . The foldable furniture of  claim 7 , wherein each of the rigid substrates comprises two layers of fabric and a fiberglass member inserted in between the two layers of fabric. 
     
     
         11 . The foldable furniture of  claim 7 , wherein each of the rigid substrates comprises two layers of fabric and a hard material member inserted in between the two layers of fabric. 
     
     
         12 . The foldable furniture of  claim 7 , wherein each of the rigid substrates comprises a carbon fiber member.
