A system (20) for controlling the effective rate at which an air bag (24) is filled comprising: a housing (22) operatively communicated with the air bag such that as the air bag is pressurized by inflation gas such gas enters the housing increasing its internal pressure, the housing (22) including: variable vent (54, 50, 52) for defining an opening through which a quantity of inflation gas is controllably diverted from the air bag to thereby reduce its rate of inflation from that rate which is achieved when the vent means is closed.
