PURPOSE: To provide a structure which is made elastic filled with compressible gas or non-compressible fluid.
CONSTITUTION: The structure consists of; the lower base fabric 1; the upper base fabric 2 which is above the fabric 1 and of almost the same size as of the fabric 1 and the rim of which is fixed with that of the fabric 1; the inner connecting thread 3 made of elastic material like rubber which connects the upper/lower fabrics at several points in a way that the connecting length is the same and the connecting points are placed at almost the same intervals; and the opening 4 for the filler with the closing device equipped for the inner space between the upper/lower fabrics. Airtight process or watertight process is made to the lower base fabric 1 and the upper base fabric 2, and the connecting part of the rim of the both fabrics. Characteristically, the inner connecting thread can be stretched in proportion to the load below a specific stretch load, and cannot be further stretched when the load exceeds the specific stretch load.
