Abstract
An apparatus (10) includes an inflatable vehicle occupant protection device (12) and a vent opening (44) for directing flow of inflation fluid away from the protection device. A vent member (46) is movable between an open condition enabling flow of inflation fluid through the vent opening and a closed condition at least partially blocking flow of inflation fluid through the vent opening. A tether (50), when tensioned, moves the vent member (46) from the open condition to the closed condition. A latch (48) has a latched condition for maintaining the vent member (46) in the closed condition and an unlatched condition for enabling the vent member to move away from the closed condition. A controller (102) is operative to actuate the latch (48). selectively to the latched condition and the unlatched condition based on at least one sensed occupant condition.
