A vehicle occupant protection apparatus ( 10 ) comprises a seat belt system ( 50 ) having a buckled condition and an unbuckled condition, and a sensor ( 56 ) for determining the buckled condition of the seat belt system. An inflatable occupant protection device ( 12 ) has a deflated condition and an inflated condition. An inflator ( 32 ) is actuatable to provide inflation fluid to inflate the inflatable device ( 12 ). The protection apparatus ( 10 ) includes an electrically energizable mechanism ( 44 ) for venting inflation fluid from the protection apparatus ( 10 ). Electric circuitry ( 40 ) is responsive to a determination of the buckled condition of the seat belt system ( 50 ) and the inflated condition of the inflatable device ( 12 ), for actuating the electrically energizable mechanism ( 44 ) to vent inflation fluid.
