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.

[ We claim:] [1.] An air bag comprising: an airtight upper sheet and an airtight lower sheet, the peripheries of both sheets being connected, said airtight upper and lower sheets prepared by weaving a composite fiber composed of a filament core and a thermoplastic polymer bonded thereto which has a melting point at least 100.degree. C. lower than that of said filament core, and then heat pressing and fusing said thermoplastic polymer so that the melted thermoplastic polymer enters the gaps between said filament cores to fill the gaps with a continuous thermoplastic polymer layer, said airtight upper and lower sheets each having said continuous thermoplastic polymer layer being overlapped to fuse the peripheries thereof together.
