Inflator insertion apparatus and method for airbag systems

摘要

Enhanced airbag modules and methods of manufacture are provided. An airbag module according to the invention may have a cushion with an inflator insertion portion through which an inflator can be inserted into the cushion after the cushion has been substantially assembled. The inflator insertion portion may have an elongated opening, which may be oriented generally along a radius of the cushion. The elongated opening may have a comparatively narrow central portion, with first and second ends that may also be narrow, or may be widened for tear restriction and/or venting. All or part of the elongated opening may be covered by a flap that restricts gas flow through the elongated opening during deployment of the cushion.
