ABSTRACT:
An apparatus for relieving overpressure conditions in the passenger compartment of a motor vehicle comprises a valve assembly that is mounted in an opening formed in an exterior wall of the compartment, the assembly includes a frame panel sized to fill the opening and having a passage formed therethrough to define an exhaust from the interior of the compartment to the exterior ambient space. Flap valve elements overlying the exhaust for allowing free flow of air in a direction from the interior of the compartment to the exterior while preventing air flow in the opposite direction. Overpressure relief support connectors mount the frame panel in the opening in the wall and are adapted to release the frame panel from its mounted position whenever the air pressure within the compartment exceeds a predetermined minimum level about atmospheric pressure.
