Specific fabric articles exhibiting very low air and/or gas permeability (even upon application of high inflation pressures) and very high tear strengths are herein disclosed and claimed. Such a specific fabric also permits the incorporation of discrete openings (through cutting, for example) through which air and/or gas introduced by an airbag inflation canister will travel. Such a specific fabric acts as a barrier to the complete introduction of high pressure inflation gases into an airbag cushion, thereby permitting a more controlled, safer inflation upon the occurrence of a collision event. Thus, the specific inventive fabric permits movement of inflation gas and/or air substantially solely through the openings within the fabric and not through the interstices between the individual fiber constituents. The inventive fabric also withstands the intense heat generated by the explosion which creates the inflation gasses and does not lose any appreciable degree of performance during and after such an inflation event. An inflation module, as well as an entire vehicle restraint system, comprising such a specific timing fabric is also contemplated within this invention.
