<p>It is a technical problem of this invention to restrain swelling at an air cushion of an air-filled product which is subjected to an extremely large load F, and in which a high internal pressure of an air chamber is required. A pair of synthetic sheets (4) having a double layer construction (1', 2') similar to synthetic sheets (1, 2) is interposed as a suspended member between an upper side synthetic sheet and a lower side synthetic sheet, the middle portions (6) of said pair of suspended members (4) being joined by stitching with thread, either end (5) of the synthetic sheets (4) being fused to the upper and lower side synthetic sheets (3). The suspended construction as described above can be used for restraining swelling of a buoyancy-adjusting device of a scuba diving etc.</p> |
