PROBLEM TO BE SOLVED: To simultaneously put air into a large number of air chambers, and to prevent an outflow of external air from the whole of air chambers even if one of sub-air chambers is damaged. SOLUTION: A multifunctional air seal object has an air injection channel formed between two external films which are laminated on each other, and a plurality of air columns formed by heat-sealing the two external films. Further, each air column has the plurality of air chambers connected to one another in a multistage manner by heat-sealing joint, and an air inlet formed between one internal film and one external film which connects the air injection channel and the air column so as to configure the plurality of air channels connecting to the air inlet. Each air channel is connected to a plurality of air ducts whose ends have openings. COPYRIGHT: (C)2008,JPO&INPIT
