Abstract

A first air bag comprises an upper cloth and a lower cloth, the peripheries of the both cloths being connected, characterized in that the upper cloth consists of an airtight sheet obtained by weaving a composite fiber composed of a filament core and a thermoplastic polymer bonded thereto which has a melting point lower than that of said filament core, and then fusing said thermoplastic polymer so that the surface of said upper cloth has a continuous thermoplastic polymer layer. A second air bag consists of a membranous material having a breaking extension of 100% or more. A third air bag comprises an elastomer body and a shape-retaining member partially attached to the elastomer body, said member being composed of elastic fibers or threads and high-modulus fibers.
