Abstract
The airbag according to the invention includes a one-piece woven bag having an upper layer, a lower layer and a joining edge. A coating or laminating layer is associated with the interior side of the upper and lower layers and the joining edge is positioned inside the bag. First and second openings are disposed along a portion of the joining edge of the bag. The first opening is closed and the second opening is associated with an inflator mechanism. In another airbag according to the invention, an opening is provided through the upper and lower layers and the opening is patched closed. A method of manufacturing an airbag includes forming a one piece bag, cutting the bag, turning the bag inside out, and closing the bag. The bag includes an upper layer, a lower layer, and a joining edge for joining the upper and lower layers. In one embodiment, the bag is cut along a portion of the joining edge to separate the upper and lower layers of the bag along a cut portion. The bag is closed through the cut portion. In another embodiment, the bag is cut through the upper and lower layers and patched to close the openings. The bag is turned inside out through the cut portion so that the coated sides of the layers and the joined edge are disposed inside the bag.
