ABSTRACT:
A device for generating pressurized fluid for inflating inflatables such as for a vehicle occupant restraint. The present generator is of the combustible chemical type having a tubular housing with radial flow discharge port means. Combustible chemical gas generating material is disposed within the housing and annularly about a central thin wall tubular casing. Longitudinally fast-burning booster charge means is disposed within the central casing and is ignited at one end of the casing. Upon ignition, the booster charge burns progressively along the length of the tubular casing causing progressive longitudinal rupture for nearly instantaneous ignition of the portions of the gas generating material adjacent the casing. The resultant substantially instantaneous ignition of the gas generating material along the full length thereof produces uniform radial burning of the gas generating material.
