An air bag (1) formed from two layers of fabric (10 11) using a one-piece weaving technique has a peripheral seam (14) at the edge of a region (7) adapted to be inflated. Beyond the seem 14 there are a plurality of chambers (40A, 40B) and gas escaping from the inflated region (7) through the seem (14) must inflate these chambers thus creating a back pressure to reduce the flow of escaping gas. <IMAGE> |
