An air bag module includes an air bag and an inflator being activatable to discharge inflator gas for inflating the air bag. The inflator has at least one discharge port through which inflator gas is discharged. A housing has a wall adjacent the discharge port of the inflator and includes at least one vent opening. The module also includes a movable member alignable with the vent opening. The movable member is movable relative to the vent opening for opening and closing the vent opening at a predetermined time during inflator activation to control the amount of inflator gas discharged into the air bag and the amount of inflator gas expelled out through the vent opening of the housing. A device is activatable during activation of the inflator to move the movable member relative to the vent opening at the predetermined time during inflator activation.
