1. 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, the housing (22) including;

    variable vent means (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;

    including at least one opening within a wall (40) of the housing (22), a door (52a,b;

    100a,b) the motion of which is controlled by an actuator (60, 60'"'"', 60") and which when moved from the opening permits inflation gas to exit therefrom;

    wherein the actuator is attached to and movable with the door, wherein a movable element (66) of the actuator is operatively connected to a securing means (70) for preventing the door from opening and wherein when the movable element is moved from the securing means the door is movable to an open position in which inflation gas is free to flow through the opening.
