Abstract
A gas generator for instantaneously supplying a gas to an inflatable bag such as a gas bag for protection of a car passenger from injuries in a collision, of the type comprising a solid gas-generating composition confined in a reaction chamber defined in a housing having a perforated wall. The reaction chamber is bounded by a wire screen which is spaced from the perforated wall, and another wire screen is arranged along the inside of the perforated wall. Adequately sized granules of SiC are packed in a space bounded by the two wire screens to efficiently absorb heat and remove solid matter from the generated gas without offering an unduly great resistance to the gas flow. Best cooling and filtering effects can be gained by the use of .alpha.-SiC granules of a sharp-edged particle shape.
