Abstract
A method for making an air bag by forming a fabric structure of filaments or yarns in the configuration of an air bag, and grafting first and/or second components onto some or all of the filaments or yarns to provide the fabric structure with increased resistance to fraying, filament or yarn pull-out, or distortion during manufacture or use of the air bag compared to non-grafted filaments or yarns. The graft component(s) may be applied to the filaments or yarns prior to, during or after formation of the fabric structure. An air bag material suitable for use in a passive restraint system is also disclosed utilizing grafted fabric substrate provided by the above described method. A passive restraint system utilizing such fabrics is also described.
