ABSTRACT:
An air bag module (10) is mounted in a vehicle seat (12). The module (10) includes an inflator (14) and a folded air bag (12) which is spaced apart from the inflator. An expandable throat (150) defines an inflation fluid passage (151) extending between the inflator (14) and the air bag (12). The throat (150) expands, upon actuation of the inflator (14), to increase the effective cross-sectional flow area of the inflation fluid passage by at least 20% and, preferably, by 50% to 100% or more. At least one wall (154) of the throat (100) moves under pressure from inflation fluid from the inflator (14) to expand the throat.
