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.
Claims5
An air bag, the air bag comprising a one-piece woven air bag having at least two layers of fabric which are interconnected by a seam, the seam serving to separate an inflatable part of the air bag from a peripheral region of the air bag, said region of the air bag being provided with a plurality of substantially hermetically sealed cells or chambers configured to inflate only upon leakage of inflating gas from the inflatable part of the air bag through said seam so as to resist the further flow of gas through the seam.
