PULSE SHAPING FOR AIRBAG INFLATORS

摘要

An inflator includes a vessel for a source of gas under pressure. A pulse shaping valving means in the form of a Belleville washer or a sliding valve actuated by a Belleville washer operates to shape the pulse of gas flowing out of the vessel. Other than for a brief initial moment the flowrate of gas has a slower value over time followed by an instantaneous more rapid value followed by a tapering off.
