Abstract
A gas bag for vehicule occupant restraining systems comprises an envelope of several fabric sections, the gas permeability of which differs, despite which all fabric sections of the envelope can be fabricated of textile material having the same consistency, particularly having the same thread density (set) when the gas permeability of the fabric is defined with due regard to the tension condition between warp and weft threads of the inflated gas bag and taking into account the dynamic behaviour of the gas permeability as a function of the weave and crimp. Fabric sections having the same consistency can be stitched with no problem in series production and the seams are of high structural strength.
