ABSTRACT:
Featured in an air bag inflator in respect of which, during assembly, there is a requirement for the ignition train to be installed last, along with a need to hermetically seal both the gas generant material and the ignition train from the environment, is the use of two independent pressure vessels, one of which contains the gas generant material, filtering and cooling elements and a separate pressure vessel having an open end into which is inserted a squib capable of being activated by an appropriate signal and which contains all of the primary and secondary ignition pyrotechnics, the open end of the pressure vessel being closed by the presence of the squib, the pressure vessel having a necked region in its length which forms a plenum chamber when mated to the second pressure vessel containing the gas generant material, etc., the circumferance of the pressure vessel containing the squib being ported in such a way as to allow the squib, when fired, to shear out, the effluent of the squib being transferred out through the breaches created at the ported locations into the plenum, the effluent in the plenum then breaching similar ports incorporated into the second pressure vessel containing the gas generant material, the effluent then dispersing into the cavity of the second pressure vessel igniting the gas generant material.
