An apparatus ( ) for inflating an inflatable vehicle occupant protection device ( ) comprises a container ( ) defining a chamber ( ). The container ( ) has an opening ( ) through which fluid can flow from the chamber ( ). A quantity of inflation fluid ( ) is in the chamber ( ). A burst disk ( ) closes the opening. The burst disk ( ) has first and second opposite major side surfaces ( ). The burst disk ( ) has a first score line ( ) on the first major side surface ( ) and a second score line ( ) on the second major side surface ( ). The burst disk ( ) is rupturable at the first and second score lines ( ) to permit inflation fluid ( ) to flow out of the chamber ( ) through the opening ( ) in the container ( ).

An apparatus ( ) for use with a removable child seat ( ) in a vehicle ( ) comprises a vehicle seat ( ) on which a removable child seat may or may not be present, and a seat belt webbing pretensioner ( ) for retracting seat belt webbing ( ) associated with the vehicle seat. A first sensor ( ) provides a first output signal in response to a vehicle collision of a magnitude above a predetermined threshold. A second sensor ( ) provides a second output signal in response to the presence of a child seat ( ) on the vehicle seat ( ). A controller ( ) receives the first and second output signals and, in response to the first output signal, actuates the seat belt webbing pretensioner ( ) when a child seat ( ) is not present on the vehicle seat ( ) and inhibits actuation of the seat belt webbing pretensioner when a child seat is present on the vehicle seat.
