Inflation body structure for an air mattress

Abstract

An inflation body structure for an air mattress, which comprises a plurality of inflation bodies arranged in parallel in a bedspread of an air mattress; each inflation body includes two separate bodies, i.e., an upper cylindrical body and a lower cylindrical body, and each body is made of two cloth pieces glued together by means of a melting-connection method; the two cylindrical bodies are furnished with air ducts 18 respectively, which are connected with intake manifolds and control valves respectively; through the control valves, the air mattress can provide different support force for different sections of a person (such as a head section, a central body section and a leg section) so as to provide an even and comfortable pressure to reduce the contact pressure between the skin and the air mattress.

What is claimed is:  
     
         1 . An inflation body structure for an air mattress comprising a plurality of inflation bodies in a bedspread of air mattress; every said inflation body including an upper cloth and a lower cloth glued together to form into an upper cylindrical body and a lower cylindrical body, and features thereof are as follows: 
 said upper cylindrical body and said lower cylindrical body each being made of two an upper cloths and a lower cloths glued together by means of a melting-connection method to form into two separate cylindrical bodies each having an air chamber; both edges of said upper cloth glued with central part of said lower cloth to form into two parallel melting-connection lines; central cloth between said two parallel melting-connection lines being used to partition said upper cylindrical body and said lower cylindrical body, i.e., to partition said inflation body into an upper air chamber and a lower air chamber.    
     
     
         2 . An inflation body structure for an air mattress as claimed in  claim 1 , wherein said cloth pieces for said upper and lower cylindrical bodies of said inflation body are made of the same material glued together; material for said upper cylindrical body of each said inflation body being selected to have different softness and thickness in accordance with a weight to be supported.  
     
     
         3 . An inflation body structure for an air mattress as claimed in  claim 1 , wherein both sides of said upper and lower cylindrical bodies of said inflation body have two melting-connection lines, which are formed with a cloth margin having a suitable width furnished on edges of said upper and lower cloths before being glued, and said cloth margins being used for connecting two adjacent inflation bodies.
