Überdruckventil, Luftsack-Entfaltung

摘要

The motor vehicle has a valve assembly operative for relieving overpressure conditions in the compartment. The valve assembly includes a frame panel mounted in an opening in the wall to fill the opening, at least one passage formed through the frame panel to define an exhaust passage from the interior of the passenger compartment to the exterior ambient space. There is a flap valve overlying the passage for allowing free flow of air in a direction from the interior of the passenger compartment to the exterior while preventing air flow in the opposite direction. There is also an overpressure relief support device mounting the frame panel in the opening in the wall for releasing the frame panel from its mounted position in the opening in the wall whenever the air pressure within the passenger compartment exceeds a predetermined minimum.
