Chair surface for folding chairs

Abstract

A chair surface for folding chairs, where the main chair surface includes hemming and a seating area. The main chair surface is mounted to the chair surface support section by the hemming. The circumference of the seating area has a surrounding seam, and the seating area comprises the shapeable seat section and the backseat section. The space between the surrounding seam and the hemming is connected by a stretchy or stretchable element to create the mounting structure. This invention is a seating area that is shapeable to form a seat section and a backrest section. It contours to the hip and does not create any tightening sensation.

I claim: 
     
         1 . A chair surface for folding chairs, comprising:
 A main chair surface consists of the hemming and the seating area;   The main chair surface is mounted to the support section of the chair surface by the hemming;   Wherein the circumference of the seating area has a surrounding seam, and wherein the seating area is shapeable into a seat section and a backrest section with the surrounding seam and the hemming connected together by a stretchable element.   
     
     
         2 . The chair surface for folding chairs of  claim 1 , wherein the seating area is made of processed nylon mesh or Oxford fabric, and the hemming and the surrounding seam is made of processed Oxford fabric. 
     
     
         3 . The chair surface for folding chairs of  claim 1 , wherein the inside edges of the hemming and the outside edges of the surrounding seam have similar configurations. 
     
     
         4 . The chair surface for folding chairs of  claim 3 , wherein the inside edges of the hemming and the outside edges of the surrounding seam have a circular configuration. 
     
     
         5 . The chair surface for folding chairs of  claim 1 , wherein cord eyes are evenly distributed along the area near the inside edges of the hemming. Cord buckles are sewn evenly to the area close to the outside edges of the surrounding seam. 
     
     
         6 . The chair surface for folding chairs of  claim 5 , wherein the stretchable element is a stretchable cord. 
     
     
         7 . The chair surface for folding chairs of  claim 6 , wherein the stretchable cord is woven through the aforementioned cord eyes and cord buckles. 
     
     
         8 . The chair surface for folding chairs of  claim 7 , wherein the two ends of the cord are joined together to create the connection structure. 
     
     
         9 . The chair surface for folding chairs of  claim 1 , wherein the stretchable element is made of multiple stretchable straps, and the composite stretchable strap forms a radial shape and spreads evenly across the area between the hemming and the surrounding seam with one end of it is sewn to the inside edges of the hemming and the other end to the outside edges of the surrounding seam. 
     
     
         10 . The chair surface for folding chairs of  claim 1 , wherein the stretchable element is a stretchable fabric, the stretchable fabric is cut into a round shape, and the inside edges and the outside edges of the surrounding seam are sewn together; and
 the outside edges and the inside edges of the hemming are sewn together.
