Abstract

A lighter, low-cost inflatable restraint module is disclosed. The inflatable restraint module may include an inflator positioned within a heat shield. The heat shield and inflator may be disposed within an inflatable cushion. A portion of the cushion containing the inflator and heat shield is situated within a chamber. The chamber may include an opening in the chamber and an extension that projects away from the opening. Attachment of a portion of the inflatable cushion to the extension keeps the portion of the cushion away from the opening of the chamber and, thus, away from potentially damaging heat generated by the inflator. Alternatively, the portion of the cushion may be kept away from the opening by attachment to a cover which is, in turn, attached to the extension. The inflator, heat shield, chamber, and cushion may be secured within an interior region of a canister.
