Abstract
Apparatus for variably controlling the burn time of a fixed amount of gas generating material used for inflating purposes. Gas developed by combustion of the gas generating material passes through a conduit. A blocking means is provided which, when selectively disposed in the conduit, decreases the cross-sectional area thereof and partially blocks the flow of the generated gas therethrough. The burn time of the gas generating material then decreases and the mass flow rate of the generated gas through the conduit is increased. The apparatus is especially adapted for use with motor vehicle passive restraint systems wherein, upon impact of the vehicle, a bag is rapidly inflated by the gas to protect passengers or other mobile objects of the vehicle.
