ABSTRACT:
The woven structure for an air bag is designed to have an air permeability which does not increase by more than about fifty percent when the fabric is subjected to substantially equivalent tension forces in both the warp and fill. This is accomplished by a multiple warp harness arrangement using combinations of twill and basket weave pattern components. This weave construction does not only avoid substantial increases in permeability over a range of biaxial tensions but also may result in a permeability decrease when subjected to tensions which approximate those applicable during actual air bag deployment.
