  • Dual-wall pyrotechnic air bag inflator with tortuous gas flow
    Patent number: 5582427
    Abstract: A dual-walled air bag inflator having a filter and gas generant within a common chamber, with the gas exiting radially from the inflator. Various arrangements are provided to force the generated gas to change its direction of travel at least 90.degree. prior to exiting in order to slow the gas and improve filtration. Gas barriers are placed within the chamber to force the desired flow. The gas flow may be directed radially inward in opposed streams to cancel velocity, and then directed radially outward toward the filter and exits. In one embodiment a mixing chamber is provided for the gas prior to encountering the filter.
