<p>PCT No. PCT/SE90/00860 Sec. 371 Date Jun. 22, 1992 Sec. 102(e) Date Jun. 22, 1992 PCT Filed Dec. 20, 1990 PCT Pub. No. WO91/09581 PCT Pub. Date Jul. 11, 1991.The present invention relates to a resilient body which includes two thin layers (1, 6) of flexible material to which intermediate elastic threads (2, 3, 5) or bands are fastened in a stretched state and disposed in a regular, net-like pattern, and bodies (4) of soft material are disposed between the two layers (1, 6) in at least some of the meshes of the net formed by the elastic threads. These bodies have smaller dimensions than the meshes, so as to permit total or partial contraction of the stretched or tensioned elastic threads. The bodies also have an intrinsic stiffness such as to substantially retain their shape upon contraction of the elastic threads. The invention also relates to a method for manufacturing the inventive resilient body.</p> |
