Abstract: An apparatus is provided for assembling an inflator and an air bag unit into an inflator-air bag assembly. The apparatus comprises a frame and a holder device coupled to the frame. The holder device includes a movable nest adapted to receive an air bag unit and an inflator. The air bag unit has at least one stud which is capable of passing through at least one stud receiving opening provided in the inflator. The nest is adapted to move the air bag unit and the inflator such that the stud is moved to a nut-applying station. The apparatus further includes a driver unit coupled to the frame which is adapted to secure the nut to the stud to assemble the inflator and the air bag unit into an inflator-air bag assembly. The apparatus additionally includes a clamping element movably coupled to the support structure for engaging the inflator when the support structure is in the nut-securement position so as to act with the nest to clamp the inflator and the air bag unit together.
