Abstract
Airbag inflator system includes an inflatable airbag, a housing and a gas generating system arranged in the housing for generating gas. The gas generating system provides variable amounts of gas to the airbag as a function of temperature. A nozzle may be arranged between the gas generating system and an interior of the airbag, the nozzle being varied as a function of temperature. The housing may be movably arranged relative to a fixed base and mounted to vary its relation to the base. To this end, elastic or temperature-deformable supports may be used to support the housing on the base. When the housing defines a chamber containing generated gas, the properties of a conduit between the chamber and the interior of the airbag can be varied as function of the pressure in the chamber.

9. In a vehicle having a passenger compartment with locations suitable for mounting of an airbag module, an airbag module adapted for mounting in the passenger compartment to protect an occupant in the event of a crash of the vehicle, comprising:
-
at least one airbag; an inflator for producing pressurized gas to inflate said at least one airbag, said inflator comprising; a housing; a gas generator arranged within said housing; a variable exit opening in said housing through which gas from said gas generator flows to inflate said at least one airbag, said variable exit opening having a plurality of different sizes such that the size of said variable exit opening is controlled by the pressure within said housing; and initiation means for initiating production of the pressurized gas in response to a crash of the vehicle.
