ABSTRACT:
A toroidal-shaped adaptive output inflator is provided wherein the inflator includes an outer housing and an inner housing together defining an outer chamber and an inner chamber. A supply of gas-generating pyrotechnic material having a burn rate that is pressure dependent is contained within the outer chamber and at least a portion of the supply of gas-generating pyrotechnic material is reactable to generate a product gas. The inflator also includes a first plurality of apertures and a second plurality of apertures each formed in the inner housing, and each providing independent fluidic communication between the outer chamber and the inner chamber wherethrough at least a portion of the product gas can exit the outer chamber into the inner chamber. An output control device positioned within the inner chamber is movable or rotatable between a first or open position allowing fluidic communication between the outer chamber and the inner chamber through the first plurality of apertures and the second plurality of apertures, and a second or closed position at least partially obstructing fluidic communication between the outer chamber and the inner chamber through at least one of the first plurality of apertures. Also provided is a control assembly in operational control communication with the inflator and associated or related methods for adjusting inflation gas output from the inflator.
