Abstract

See full text

An airbag inflation apparatus includes a chamber for generating a gas to inflate an airbag. A valve, including a magnetic fluid and a source of magnetic field, preferably an electromagnet, is associated with the chamber for regulating the flow of the gas into the airbag. A sensor determines and feeds occupant information to the sensor.
