Abstract
An apparatus (10) includes a pressure vessel (16) comprising a source of inflation fluid, and a solenoid valve (24) which regulates an outlet flow of the inflation fluid from the pressure vessel (16). The solenoid valve (24) normally has an open condition providing an initial outlet flow area. The apparatus (10) responds to a vehicle crash by controlling the solenoid valve (24) in a selected one of a plurality of differing stages corresponding to a plurality of differing conditions. The different stages include a stage in which the solenoid valve (24) is not shifted from the open condition, and further include a stage in which the solenoid valve (24) is shifted to a further opened condition providing a subsequent outlet flow area greater than the initial outlet flow area.
