Abstract
A pyrotechnic air bag inflator utilizing non-azide gas generating material such as mixtures of copper oxide and amino tetrazol includes a unitary, rigid, drop-in type, filter for cooling and filtering high temperature, high pressure corrosive gas generated when the air bag inflator is activated to inflate an associated air bag. The filter comprises a reticulated structure formed of strong, porous, metal, metal alloy or ceramic material having a high thermal diffusivity and surface area for absorbing heat from the gas and defining a plurality of tortuous passages for entrapping contaminants from the gas passing through the filter.
