Abstract:
1. A one-piece woven air bag comprising: a coating; and single-layer and two-layer portions, including upper and lower outer surfaces having the coating applied thereon, the portions being woven together as a single fabric structure with the two-layer portion defining an inflation chamber; the single-layer portions being internally sealed in a woven plane such that they are substantially impermeable to fluids; the single-layer portions being provided at least in part with denser woven structure portions and with a less densely woven structure as compared to the density of the two-layer portion; the coating on the upper and lower outer surfaces of the single-layer portions penetrating deeper into the air bag at the less densely woven structure as compared to the denser woven structure portions, the coating penetrating so deeply into the less densely woven structure portions that the coating from each outer surface comes into contact in the interior of the single-layer portions.
