Abstract
A leaf screen for an air intake of an HVAC system of a vehicle having a hood covering an engine compartment. The leaf screen includes a leaf screen body defining an air inlet opening covered by an integrally molded screen. A seal is integrally molded on a top surface of the leaf screen body in front of the air inlet opening. Bump-stops are integrally molded on the top surface that are engaged by an inner panel of the hood when closed. A method of making the leaf screen includes injecting a polymeric material into a mold to form a body portion. At least one elastomeric material is injected into the mold on one side of the body portion to form a seal and a plurality of bump-stops.
