Method for inflating an airbag in a vehicle to protect an occupant in the
event of a crash involving the vehicle in which an inflator having a
propellant is arranged in the vehicle, the propellant is ignited after
determination of a crash involving the vehicle to generate gas therefrom,
the gas is directed into an airbag and pressure in the airbag is
controlled based on the occupant by varying the flow of gas into the
airbag. Variation in the flow of gas into the airbag may be obtained by
varying a flow of aspirating gas into a mixing chamber in which the
aspirating gas mixes with gas generated from the propellant.
