Dual depth airbag

摘要

An air restraint system has an airbag which is deployable between an instrument panel and an occupant seat within an automotive vehicle. The airbag includes first and second air chambers which are separated to restrict flow therebetween by a single panel member. The first and second chambers of the airbag are selectively pressurizable with a gaseous fluid which is distributed from an inflator through a plurality of passages, and the flow therein is controlled by a valve member. The valve member is operable to distribute the pressurized fluid to one chamber, both of the chambers of the airbag or to the atmosphere.
