Patent attributes
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.
