To achieve programmed inflation of an airbag in a vehicle occupant restraint apparatus, movement of a piston, that separates a combustion chamber from a liquid propellant reservoir, is utilized to vary the opening size of an injection port through which liquid propellant is regeneratively pumped from the reservoir into the combustion chamber for combustion, such that the rate at which the bag inflation gas is generated during an inflation period may be controlled.
An occupant restraint apparatus for installation in a vehicle, comprising: an inflatable airbag; a housing having a vent in fluid communication with the airbag; a cylinder provided in the housing; a piston slidably received in the cylinder to define, to a back side, a reservoir containing a liquid propellant and, to a front side, a combustion chamber in fluid communication with the housing vent; a sensor; an inflation initiator operable, in response to a vehicle collision detected by the sensor, to generate fluid pressure in the combustion chamber that a...
