Patent ID: 7341769

Claim:
An air bag comprised of a laminated fabric, said laminated fabric comprising an elastomeric film which has been prepared by a casting or extrusion process and which is laminated to manmade fiber substrate fabric, wherein the elastomeric film is comprised of at least 70% by weight of a copolyetherester (A) having a multiplicity of recurring long-chain ester units and short-chain ester units joined head-to-tail through ester linkages, said long-chain ester units being represented by the formula: and said short-chain ester units being represented by the formula: wherein: a) G is a divalent radical remaining after the removal of terminal hydroxyl groups from a poly(alkylene oxide)glycol having a number average molecular weight of about 400-4000; b) R is a divalent radical remaining after removal of carboxyl groups from a dicarboxylic acid having a molecular weight less than 300; c) D is a divalent radical remaining after removal of hydroxyl groups from a diol having a molecular weight less than about 250; wherein the copolyetherester contains about 25-80 weight percent short-chain ester units, and wherein the laminated fabric has a stiffness of from about 5 to 80 Newtons measured according to test method ASTM D4032-94.
