Abstract
The present invention relates to an inflatable occupant restraint device having an inflator, an outer bag disposed around the inflator to allow the outer bag to be filled with gas produced by the inflator, an inner bag, disposed in between the outer bag and the inflator, wherein the inner bag is made of a flexible material having at least one flow outlet in the flexible material altering the flow of gas produced by the inflator. The inner bag protects the outer bag from hot gases and particles emanating from the inflator. The inner bag may also have a pattern of stitched seams forming gas flow outlets to impart a desired flow pattern to the inflating gases.
