LOAD CARRYING shock absorbing device with improved gas-tight material FOR CONTROLLING THE DIFFUSION PUMPS.

摘要

A product in the form of a shock absorbing device made from a thermoplastic film containing crystalline material and inflated to a relatively high pressure and sealed during manufacture. The improved and new shock absorbing devices utilize new materials for the enclosure sheath film that selectively control the speed of diffusion pumping, allowing greater flexibility in the width and greater precision in the design of such new shock absorbing devices is. It is possible to permanently inflate certain types of new devices using readily available gases such as nitrogen or air, in which case nitrogen forms the gas to be contained.
