1. A strong lightweight airbag cushion for deployment in opposing relation to a vehicle occupant during a collision event, the cushion comprising:
- a body of wound yarn including an interior, a face portion for contact with the vehicle occupant and a rear portion including an inlet port for the introduction of an inflation medium into the body, wherein the body is formed by windings of yarn such that the yarn is evenly distributed across said face portion of said body, and wherein at least some of said yarn crosses an equatorial plane between said face portion and said rear portion at an angle of between about 46° and
about 90°
, and such that the yarn is disposed preferentially across the back of said body in the area surrounding the inlet port so as to form a localized region of enhanced thickness around the inlet.

Abstract
A strong lightweight airbag cushion for deployment in opposing relation to a vehicle occupant is provided. 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 that region.

16. A multi-layer airbag cushion, comprising:
- a body of wound yarn including an interior, a face portion for contact with a vehicle occupant and a rear portion including an inlet port for the introduction of an inflation medium into the body, a thin film disposed across at least a portion of the interior of said body, and a flexible permeability blocking coating over said body and film, wherein the body is formed by winding at least one substantially continuous yarn over said film so that at least some of said yarn crosses an equatorial plane between said face portion and said rear portion at an angle of between about 46° and
about 90°
, and then applying said blocking coating over said wound yarn and film. - View Dependent Claims (17, 18)
