ABSTRACT:
An improved fabric material for producing woven air bags utilized for protecting riders in vehicles. The fabric material is composed of a plurality of tubular weave portions formed along the warp direction and a stitched portion formed between two adjacent tubular weave portions. Each stitched portion is provided with at least single small tubular weave construction formed along a warp direction. The warp yarns forming the face fabric of a large tubular weave portion and the warp yarns forming the back fabric of the large tubular weave portion are respectively used as the warp yarns for forming the back fabric of the successive small tubular weave construction and the warp yarns for forming the face fabric of the successive small tubular weave construction. Woven air bags are produced by cutting the central portion of the stitched portion along a weft direction. The fabric material may be coated with a thin layer of coating resin material.
