Abstract

An apparatus (10) for inflating an inflatable vehicle occupant restraint (12) includes a collision sensor (52) and an inflator assembly (20). The collision sensor (52) provides a collision signal indicating the occurrence of a vehicle collision. The inflator assembly (20) includes a first source (22) of inflation fluid which, when actuated, provides a first volume of inflation fluid. The inflator assembly (20) further includes a second source (24) of inflation fluid which, when actuated, provides a second volume of inflation fluid which differs from the first volume. A position sensor (70) provides a position signal indicating a position of an occupant of the vehicle. A
controller (50) actuates the first and second sources (22, 24) of inflation fluid in any one of a plurality of differing modes of operation in response to the collision signal and the position signal.
