Inflatable vehicle occupant protection device with inflation fluid deflector

摘要

An apparatus (10) for helping to protect an occupant (16) of a vehicle (12) comprises an inflatable vehicle occupant protection device (14) that is inflatable from a deflated condition to an inflated condition. An inflator (32) is actuatable to provide inflation fluid to inflate the protection device (14). A retainer (70) has an opening (78) for receiving the inflator (32). The retainer (70) includes a base portion (72) and an annular wall (74) that extends transversely from the base portion (72). The annular wall (74) has a deflector portion (88) and a retaining portion (86). The deflector portion (88) is positioned radially outward from the retaining portion (86) and extends substantially orthogonal to the base portion (72) to direct inflation fluid from the inflator (32) into the protection device (14) in a direction substantially parallel to a central axis (37) of the inflator (32). The retaining portion (86) extends radially inward from the deflector portion (88) and clamps a flange (35) of the inflator (32) to a support member (34).
