ABSTRACT:
An air bag of the type utilized in a vehicle occupant restraint system is constructed of a plurality of panels of uncoated fabric. Respective of the panels have been processed to achieve a selected air permeability with greater accuracy on a lot-to-lot basis than had generally been achieved with uncoated fabrics of the prior art. In one presently preferred methodology, a plurality of fluid jets, preferably water jets, are utilized to impact panels of the uncoated fabric under selected operating conditions. Pores created by the fluid jets may be heat set to achieve a selected permeability. Fluid jet processing may also be utilized to produce a fabric having a selected thread count.
