Abstract

An airbag module has a rigid cushion with an integrated inflator. The cushion has a rear cushion panel and the inflator may have a front inflator plate attached to the rear cushion panel. A rear inflator plate is optionally provided and may be positioned within the cushion or outside the cushion. A pyrotechnic may be disposed within the space between the front inflator plate and the rear cushion panel and/or the rear inflator plate. An initiator may be seated in the rear inflator plate and/or the rear cushion panel to initiate combustion of the pyrotechnic. Instead of the front inflator plate, the inflator may have an expanse of tape that secures the pyrotechnic and/or the initiator to the interior of the cushion. The pyrotechnic may be sealed by the tape or by a foil pouch. The initiator may be secured by the tape or by a rear inflator plate.
