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. ## Claims ### Claim 1 A vehicle comprising: a body defining an engine compartment; a hood assembled to the body; a leaf screen defining an air inlet behind the engine compartment; a seal provided on a top surface of the leaf screen and engages an inner panel of the hood; and a plurality of bump-stops provided on the top surface that are engaged by the inner panel when the hood is closed. ### Claim 2 (depends on 1) The vehicle of claim 1 wherein the seal is integral with the leaf screen, the leaf screen having a body portion, wherein the seal extends upwardly from the body portion. ### Claim 3 (depends on 2) The vehicle of claim 2 wherein the seal is formed of an elastomeric material that is softer than a polymeric material forming the leaf screen. ### Claim 4 (depends on 1) The vehicle of claim 1 wherein the bump-stops are integral with the leaf screen, the leaf screen having a body portion, wherein the bump-stops extend upwardly from the body portion. ### Claim 5 (depends on 4) The vehicle of claim 4 wherein the bump-stops are formed of an elastomeric material softer than polymeric material forming the leaf screen. ### Claim 6 (depends on 1) The vehicle of claim 1 wherein the seal and the bump-stops are integral with the leaf screen, wherein the seal is formed of a first elastomeric material softer than the than a second elastomeric material forming bump-stops, and wherein the second elastomeric material is softer than a polymeric material forming the leaf screen. ### Claim 7 A method of making a leaf screen comprising: injecting a polymeric material into a mold to form a body portion; injecting at least one elastomeric material into the mold on a first side of the body portion to form a seal and a plurality of bump-stops; cooling the polymeric material and the elastomeric material in the mold, solidifying and joining the polymeric material and the elastomeric material; and removing the leaf screen from the mold. ### Claim 8 (depends on 7) The method of claim 7 wherein the at least one elastomeric material includes a first elastomeric material for forming the seal and a second elastomeric material for forming the bump-stops. ### Claim 9 (depends on 7) The method of claim 7 wherein the at least one elastomeric material is a single elastomeric material for forming the seal and the bump-stops. ### Claim 10 (depends on 7) The method of claim 7 wherein during the cooling step the polymeric material and the elastomeric material bond to each other. ### Claim 11 (depends on 7) The method of claim 7 wherein the seal is formed along a portion an air vent opening defined by the leaf screen that is covered by a hood of a vehicle when the hood is closed. ### Claim 12 (depends on 7) The method of claim 7 wherein the bump-stops are spaced apart across the lateral width of the leaf screen. ### Claim 13 A leaf screen for an intake of an HVAC system of a vehicle having a hood covering an engine compartment, comprising: a leaf screen body defining an inlet opening; a seal integrally molded on a top surface of the leaf screen body partially surrounding the inlet opening and engaging the hood; and a plurality of bump-stops integrally molded on the top surface that are engaged by the hood when closed. ### Claim 14 (depends on 13) The leaf screen of claim 13 wherein the seal extends upwardly from the leaf screen body. ### Claim 15 (depends on 14) The leaf screen of claim 14 wherein the seal is formed of an elastomeric material softer than a polymeric material forming the leaf screen body. ### Claim 16 (depends on 13) The leaf screen of claim 13 wherein the bump-stops extend upwardly from the leaf screen body. ### Claim 17 (depends on 16) The leaf screen of claim 16 wherein the bump-stops are formed of an elastomeric material softer than a polymeric material forming the leaf screen body. ### Claim 18 (depends on 13) The leaf screen of claim 13 wherein the seal is formed of a first elastomeric material softer than a second elastomeric material forming bump-stops, and wherein the second elastomeric material s softer than a polymeric material forming the leaf screen body.
