Abstract
A lightweight airbag cushion for deployment in opposing relation to a vehicle occupant is provided. In one embodiment, the cushion is formed from a body of wound yarn which has an enhanced elongation to break. The body includes an interior, a face portion for contact with the occupant and a rear portion including an inlet port for the introduction of an inflation medium. The body is formed by the continuous winding of yarn around a mandrel such that the yarn is spread across the face and is disposed preferentially across the back in the area surrounding the inlet port so as to provide added strength in that region.
