Abstract
A pressure relief assembly includes a housing defining an air passage chamber having at least one airflow opening. A flap is secured within the air passage chamber. The flap is configured to move into an open position to expose the airflow opening(s) to relieve air pressure. A cushion is secured to the housing underneath the flap. The cushion is configured to cushion motion of the flap. A first attachment securely couples the flap to the housing. A second attachment securely couples the cushion to the housing. The first attachment is separate and distinct from the second attachment.
