Abstract

A side impact air bag inflator (14) includes an elongated tubular member (40) having an open end (52), a closed end portion (44), and a cylindrical portion (42) with a uniform inner diameter (d1) and a plurality of outlet openings (38). A rupturable closure wall (82) is fixed to the tubular member (40) at a location axially between the outlet openings (38) and the closed end portion (44). Inflation fluid is contained under pressure within the tubular member (40) between the closure wall (82) and the closed end portion (44). An initiator (100) has a cylindrical casing (106) extending coaxially within the tubular member (40) at a location axially between the closure wall (82) and the open end (52). A circular base (102) of the initiator (100) closes the open end (52).
