Abstract
A one-way air valve for relieving pressure within the passenger compartment of an automobile includes a plastic frame having an air passage therethrough with a flap integrally molded with the frame but of more elastic material and connected to the frame by a living hinge. The flap is molded in a position extending through the passageway and the living hinge is spring loaded by swinging the flap back through the passageway to overlie the outside of the frame over the passageway, thereby biasing the flap against the frame.
