ABSTRACT:
An air bag module (10) comprises an inflatable vehicle occupant restraint (12), an inflator (18) having first and second axial end walls (64, 66), and a diffuser (20) having first and second end walls (90, 92). A chamber (94) extends between the first and second end walls (90, 92) of the diffuser (20). The first axial end wall (64) of the inflator (18) is supported in the chamber (94) at the first end wall (90) of the diffuser (20), and the second axial end wall (66) of the inflator (18) is supported in the chamber (94) at the second end wall (92) of the diffuser (20). The module (10) further includes an end cap (26) which is fastened to the first end wall (90) of the diffuser (20) in a fastened position. The end cap (26) imparts an axially directed supporting force to the inflator (18). The supporting force urges the inflator (18) axially inward of the chamber (94) at the first end wall (90) of the diffuser (20), and urges the inflator (18) axially outward of the chamber (94) at the second end wall (92) of the diffuser (20).
