A vehicle occupant protection apparatus ( ) comprises an inflatable vehicle occupant protection device ( ) and an inflator ( ) for providing inflation fluid for the inflatable device. The inflator ( ) has a relatively large diameter body portion ( ) and a relatively small diameter neck portion ( ) extending from the body portion. The neck portion ( ) has an inflation fluid outlet ( ). The occupant protection apparatus ( ) also comprises a conduit ( ) for directing inflation fluid from the inflator ( ) into the inflatable device ( ). The conduit ( ) has a relatively large diameter main body portion ( ) secured on the body portion ( ) of the inflator ( ) by interfitting portions ( ) of the main body portion and the body portion of the inflator. The main body portion ( ) of the conduit ( ) defines a fluid chamber ( ) around the neck portion ( ) of the inflator ( ). The conduit ( ) has a relatively small diameter fill tube portion ( ) for location in the inflatable vehicle occupant protection device ( ). The conduit has a neck portion ( ) extending between the main body portion ( ) and the fill tube portion ( ). The neck portion ( ) of the conduit ( ) tapers in diameter from the main body portion ( ) to the fill tube portion ( ).

An air bag inflator (,) includes a container (,) defining a chamber (,), and inflation fluid (,) under pressure in the chamber. A first opening (,) in the container (,) enables fluid flow from the chamber (,) to an inflatable device (,). A first burst disk (,) extends across the first opening (,) and is rupturable in response to an increase in the pressure differential across the first burst disk to a level above a first predetermined pressure differential. The inflator (,) includes a first igniter (,) for, when actuated, increasing the pressure differential across the first burst disk (,) to a level above the first predetermined pressure differential to rupture the first burst disk. A second opening (,) in the container (,) enables fluid flow from the chamber (,) to the inflatable device (,). A second burst disk (,) extends across the second opening (,) and is rupturable in response to an increase in the pressure differential across the second burst disk to a second predetermined pressure differential greater than the first differential. The inflator (,) includes a second igniter (,) actuatable independently of the first igniter (,) for, when actuated, increasing the pressure differential across the second burst disk (,) to a level above the second predetermined pressure differential to rupture the second burst disk.
