Abstract
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 includes at least one inflator vent opening aligned with the discharge port. A variable inflation device is mounted on the inflator and 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. Preferably, the variable inflation device includes an initiator device being activatable during activation of the inflator to move the movable member relative to the vent opening at the predetermined time during inflator activation.
