Abstract
An air bag module in a vehicle includes an inflator for generating gas to inflate an air bag. The air bag has a first portion adjacent the inflator and operatively connected to the inflator for receiving the inflator gas therein. The air bag has a second portion extending from the first portion and spaced apart from the inflator by the first portion. The second portion is unidirectionally rolled to define a rolled portion. Prior to air bag inflation, the first portion is stored atop the inflator and the rolled portion is stored atop the first portion. Preferably, the rolled second portion forms a pinch point between the first portion and the second portion such that the first portion partially inflates prior to unrolling of the second portion. Preferably, the first portion is folded in manner to inflate more readily than the rolled second portion such that the first portion inflates and forces the rolled second portion outwardly away from the inflator prior to unfolding of the rolled second portion.
