Mechanical lock assembly for a driver side inflator.

摘要

Airbag inflator module assembly (10) including a module housing (14) with a circular aperture having radially extending slots (38) and an inflator (12) with tapered flanges (26) which engage the housing slots (38) upon rotation of the inflator with respect to the housing to clamp an aperture bounding portion of the housing (14) between a radially extending flange of the inflator and the flanges (26). A recess engaging bump may be provided on the flange (26) or the housing (14) to resist counter-rotation of the inflator. The bump may alternatively engage a trailing edge of the flange. A separate bracket may provide rotational engagement with the housing in place of flanges formed integrally with the inflator. <IMAGE>
