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

摘要

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 ).
