<P>PROBLEM TO BE SOLVED: To provide a cushion body wholly having nonuniform hardness of a soft area which is desired to be soft and a hard area which is desired to be hard, without independently controlling the amount of gas filled into a plurality of gas chambers. <P>SOLUTION: The cushion body 1 is formed with the gas chambers 6 enclosed by film-like bodies 2 and 3 by partially joining the film-like bodies 2 and 3 forming two opposite surfaces to each other. In the cushion body 1, an area desired to be soft has a smaller distance between parts 4, 5, and 11 at which the two surfaces formed from the film-like bodies 2 and 3 are joined to each other, and an area desired to be hard has a larger distance between the parts 4, 5, and 11 at which the two surfaces are joined to each other. <P>COPYRIGHT: (C)2010,JPO&INPIT |
