Abstract

A linear gas generant to be used in, for example, a gas generator for rapidly launching a flier such as a rocket or for rapidly inflating an air bag in a motor vehicle characterized by disposing a fibrous substance, such as copper, silver, aluminum or carbon, along the axial direction thereof. This linear gas generant can be stably deflagrated under a lower ambient pressure, irrespective of a large specific burning area. Disclosed further is a filter structure for a gas generator to be used in an air bag restraint system, which is produced by winding a continuous high-tensile-strength fiber bundle or yarn at a predetermined pitch around an outer surface of a member (a gas generation member) comprising ignition means and gas generation means actuated by the ignition means. This filter structure attains the reduction in weight of the gas generator.
