Abstract
An apparatus (10) for inflating an inflatable vehicle occupant protection device (12) includes a housing (16, 40) defining a chamber (30). An actuatable inflation fluid source (80) in the chamber (30) provides inflation fluid for inflating the inflatable device (12). A body of plastic material (50) is supported on the housing (40). An electrically energizable initiator (90), when energized, causes inflation fluid to flow from the chamber (30). A retainer (120) mounts the initiator (90) to the housing (40). The retainer (120) has a first portion (130) engaging the initiator (90) and securing the initiator to the retainer. The retainer (120) has a second portion (132) engaging the body of plastic material (50) and securing the retainer to the body of plastic material.
