Abstract:
An inflatable airbag cushion comprising: a woven bag of non-jacquard construction, wherein said bag comprises a face portion and a rear portion formed from a first fabric layer and a second fabric layer, each of said first and second fabric layers being defined by a plurality of polymeric warp yarns running in a warp direction interposed by a plurality of polymeric weft yarns running in a weft direction substantially transverse to said warp direction; said bag further comprising a plurality of woven in joints, said woven in joints being arranged so as to define flow barriers between said face portion and said rear portion such that upon introduction of a gas into said bag, the flow of the gas within the bag is limited by said woven in joints thereby containing the gas in locations where inflation is desired and restricting inflation of said bag at locations where said woven in joints are present; at least a portion of at least one of said woven in joints extending in both the warp direction and the weft direction between said face portion and said rear portion, and all of said woven in joints in said woven bag consisting essentially of one or more straight line segments, at least one of said woven-in joints forming at least one of a closed edge and end between said face portion and said rear portion to prevent gas from escaping from said airbag cushion upon the introduction of gas into said cushion, and wherein at least one of said flow barriers comprises at least one of a box structure, an extended box configuration, an island, a stepped corner profile, and a cross shape.
