Abstract
An air bag formed from two layers of fabric using a one-piece weaving technique has a peripheral seam at the edge of a region adapted to be inflated. Beyond the seam there are a plurality of chambers and gas escaping from the inflated region through the seam must inflate these chambers thus creating a back pressure to reduce the flow of escaping gas.
