Patent number: 6705672Abstract: An air-conditioning duct structure is included in a vehicular dash beam member. Material for the duct is made of a heat insulating and sound absorbing material and is adhered onto the surface of a sheet material for the beam member which is then bent into a semi-tubular shape so that the material for the duct is positioned inside thereby forming beam member bodies. Beam member bodies are combined by joining their joining surfaces that face each other to thereby form a tubular closed sectional shape. Achieving vibration attenuation, noise absorption and the heat insulating functions with an inner surface sheet member of an air conditioning duct is achievable. An air conditioning duct extending across a vehicle's width is formed by joining a metal reinforcing member and a resin cover. The sheet member is put between the reinforcing member and the cover.Type: GrantFiled: April 9, 2002Date of Patent: March 16, 2004Assignee: Denso CorporationInventors: Kazushi Shikata, Tomohiro Kamiya, Koichi Ito, Takahiro Yoshida, Mikio Hirano, Satoshi Mizutani

Patent number: 6382712Abstract: A single piece injection molded air distribution member carried by the steering wheel support structure forms three sides of an air duct with the fourth side of the air duct left open. The open side is positioned adjacent to the vehicle windshield where the windshield forms the fourth side of the air duct. Since the distribution member does not form an enclosed air duct, the distribution member can be made as a single piece injection molded component. The distribution member is placed in contact with the glass or slightly spaced from the glass. If spaced from the glass, a continuous layer of air flows from the distribution member over the surface of the glass. The distribution member has vanes that divide the duct into multiple air channels, each terminating in an air outlet.Type: GrantFiled: June 19, 2001Date of Patent: May 7, 2002Assignee: Deere & CompanyInventor: Paul Thomas Bruss

Patent number: 6309012Abstract: A one piece rotational molded roof for a vehicle cab is provided in which separate inlet and outlet air ducts are molded in the roof. The ducts are formed by molding upper and lower panels that are widely spaced to form the ducts and which are closely spaced about the periphery of the ducts. After a solid surface layer is molded, a second resin charge containing a foaming agent is dropped in the mold. This resin coats interior of the solid surface layer and later foams. The foam expands and extends completely between the closely spaced upper and lower panels of the solid surface layer to seal between the inlet and outlet air ducts. The foam is rigid to strengthen the roof.Type: GrantFiled: April 18, 2000Date of Patent: October 30, 2001Assignee: Deere & CompanyInventors: Bruce Kevin Fryk, Dean Arden Boyce, Shawn Michael Bartz
