(54)Vehicle pressure relief valve having centrally secured flaps and method of manufacturing the same


(57) A pressure relief valve (12) for relieving air pressure from a passenger compartment (14) of a vehicle (10) includes a base (18) having a central portion (26) and a peripheral portion (28). A plurality of openings (46) extends through the base (18) and a plurality of flaps (60) closes the openings (46). Each flap (60) is associated with at least one opening (46). An inner end (66) of each flap (60) connects with the central portion (26) of the base (18). An outer end (68) of each flap (60) is movable relative to the central portion (26) of the base (18) and the other flaps for enabling airflow through the at least one associated opening (46). The pressure relief valve (12) further includes a connector (22) on the base (18) that is configured for securing the pressure relief valve (12) to the vehicle (10).
