Abstract

An airbag mounting system for orienting an inflator, a retaining ring, an airbag cushion and a housing module of an airbag module assembly. The assembly includes an annular retaining ring having a plurality of first fastener openings circumferentially spaced about the ring. At least two of the plurality of first fastener openings being spaced from each other along the ring circumference by a first angle. At least one of the plurality of first fastener openings is offset from at least one of the at least two first fastener openings by a second angle different from the first angle. A module housing includes a plurality of second fastener openings circumferentially spaced about a central inlet opening. At least two of the second fastener openings are spaced from each other along the circumference by a third angle. At least one of the second fastener openings is offset from at least one of the at least two second openings by a fourth angle which is different from the third angle. An airbag having a gas inlet opening corresponding with the central opening of the module housing includes a plurality of third fastener openings circumferentially spaced about the gas inlet opening. At least two of the third fastener openings are spaced from each other along the circumference by a fifth angle. At least one of the third fastener openings is spaced from at least one of the at least two third openings by a sixth angle different from the fifth angle. Upon assembly the at least one of the first fastener openings is aligned with the at least one of the second and third fastener openings. A fastening stud extends through each of the plurality of first, second and third fastener openings for securing the retaining ring, airbag and housing module together.
