Abstract
An air bag module (12) is mounted for rotation with a vehicle steering wheel (14) which has a steering axis (90). The module (12) includes an inflator (10) having separately actuatable first and second stages (40, 40a). The stages (40, 40a) include, respectively, first and second chambers (60, 60a) and an inflation fluid source (120, 120a) in each chamber for providing inflation fluid to inflate an air bag (16). An axis (58) of the first chamber (60) extends parallel to and is spaced apart from an axis (58a) of the second chamber (60a). The axes (58, 58a) of the chambers (60, 60a) extend transverse to the steering axis (90) on opposite sides of the steering axis.
