Abstract
A vehicle occupant protection apparatus (10) includes an inflatable occupant protection device (12) and a support member (40) having a vent opening (50) through which inflation fluid may flow. The apparatus (10) also includes a mechanism (58) for controlling a flow of inflation fluid through the vent opening (50). Inflation fluid pressure within the inflatable occupant protection device (12) tends to move the mechanism (58) for increasing a flow of inflation fluid through the vent opening (50). The mechanism (58) is responsive to inflation of the inflatable occupant protection device (12) beyond a predetermined distance for restricting the flow of inflation fluid through the vent opening (50). The apparatus (10) further includes a locking member (96) for blocking the mechanism (58) from increasing the flow of inflation fluid through the vent opening (50) after the inflatable occupant protection device (12) has inflated beyond the predetermined distance.
