Abstract
An air bag inflator (10) includes inflation fluid stored in a chamber (18). The inflator (10) includes a combustible sheet member (100) which comprises an oxidizable substrate, such as a polytetrafluoroethylene film, and a layer of a fuel material, such as magnesium, on the substrate. The combustible sheet member (100) is disposed in a perforated tube (90) in the chamber (18). The combustible sheet member (100), when ignited by an igniter (70), emits combustion products through openings (98) in the perforated tube (90) to warm and increase the pressure of the inflation fluid in the chamber (18). The inflation fluid includes 5% to 20% oxygen to support the combustion of the combustible sheet member (100).
