  • Vehicle pressure relief valve having peripherally secured flaps and method of manufacturing the same
    Patent number: 7302962
    Abstract: A pressure relief valve (12) for relieving air pressure from a passenger compartment (14) of a vehicle (10) includes a base (18) having a peripheral portion (30). A central opening (42) extends through the peripheral portion (30). The pressure relief valve (12) also includes a plurality of flaps (74) for closing the central opening (42) of the base (18). Each flap (74) has an outer end (82) connected with the peripheral portion (30) of the base (18) and an inner end (80) that is movable relative to the peripheral portion (30) and the other flaps (74) for enabling airflow through the central opening (42). Each flap (74) has opposite surfaces (76 and 78) against which air pressure acts. Differential air pressure acts on the opposite surfaces (76 and 78) causing the flap (74) to move to enable airflow through the central opening (42).

  • Vehicle pressure relief valve having centrally secured flaps and method of manufacturing the same
    Patent number: 7182093
    Abstract: 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).
