In an occupant restraint apparatus for installation in a vehicle, a smart airbag inflator is provided with a piston for regeneratively pumping liquid propellant from a reservoir into a combustion chamber for ignition and combustion to generate airbag inflation gases. To control the airbag inflation rate, the piston includes a piston head slidingly received in a damping chamber filled with a magneto-rheological fluid that is pumped through an orifice during the regenerative pumping stroke of the piston. An electromagnet is selectively energized to produce...
[ We claim:] [1.] An occupant restraint apparatus for installation in a vehicle, comprising:an airbag; andan inflator including:a combustion chamber in fluid communication with the airbag;a reservoir containing a liquid propellant;a port fluidically interconnecting the combustion chamber and the liquid propellant reservoir;an inflation initiator operable, in response to an accident involving the vehicle, to pressurize the liquid propellant reservoir, such that the liquid propellant is injected through the port into the combustion chamber for ignition and...
