Abstract
A strong lightweight airbag cushion for deployment in opposing relation to a vehicle occupant and the method of making same. The cushion is formed from a body of wound yarn. 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 the region adjacent the port that is located at a radial distance greater than the radius of said port. This is accomplished by shifting or shogging the yarn supplying mechanism relative to the cushion mandrel.
