Patent number: 11104098Abstract: A fibrous vehicle underbody shield and method for manufacturing the same is provided. A binderless core of non-woven fibrous material defines first and second surfaces of the fibrous vehicle underbody shield. The second surface of the fibrous vehicle underbody is opposite the first surface such that the first and second surfaces are separated by a final product thickness. The first and second surfaces include at least one molded contour that gives the first and second surfaces a non-planar shape. The non-woven fibrous material of the binderless core includes a plurality of fibers that are mechanically entangled with each other and have a coating that withstands a heat exposure of 200 degrees Celsius. The fibrous vehicle underbody shield includes a latex impregnation.

Patent number: 9908485Abstract: An acoustic barrier assembly for a vehicle and a method of manufacturing the same is disclosed. A decoupler layer surrounds a pass-through opening in a wall of the vehicle to defining a decoupler aperture that is open to the pass-through opening. A barrier layer abuts the decoupler layer and defines a barrier aperture that is also open to the pass-through opening. An acoustic seal is integrally formed in the barrier layer. The acoustic seal defines an exposed region of the barrier layer that is not bounded by the decoupler layer. The exposed region of the barrier layer directly contacts the wall around the pass-through opening and seals around a penetrating member that extends through the pass-through opening. The acoustic seal thus reduces flanking noise traveling through a gap between the penetrating member and the pass-through opening.Type: GrantFiled: November 5, 2015Date of Patent: March 6, 2018Assignee: Cadillac Products Automotive CompanyInventors: James Check, Kenneth Ritzema, Michael Demo

Patent number: 9216526Abstract: An injection compression molding system includes a mold having a fixed first half and a displaceable second half. The second half is initially positioned with a cavity between the mold halves having a first clearance sized to receive a molten material puddle shot injected by an injection molding device without the puddle shot filling the cavity. A displacement device acts during or immediately after puddle shot injection, displacing the second mold half toward the first mold half creating a second clearance less than the first clearance. The second clearance defines a finished part thickness whereby displacement of the second mold half to the second clearance compresses the puddle shot so that the puddle shot fills the cavity and forms a finished part between the mold halves. Total time to inject and compress the puddle shot is less than or equal to 1.0 seconds.Type: GrantFiled: October 30, 2014Date of Patent: December 22, 2015Assignee: Cadillac Products Automotive CompanyInventors: Robert J.

Patent number: 9205701Abstract: A removable wheel cover includes a dome-shaped body having a perimeter edge and a central core. A body elevation increases from the perimeter edge to a maximum elevation between the perimeter edge and the central core. Concentric raised ribs between the perimeter edge and the maximum elevation decrease in diameter between successive raised ribs toward the maximum elevation. A central core sleeve wall has an end face. An apex of each of multiple sleeve wall tabs positioned proximate the end face together define a first plane positioned with respect to a perimeter edge second plane. A wheel having a central hub is mounted to a tire. In an installed position, the perimeter edge is positioned in continuous contact with the tire or the wheel and the body is elastically deflected toward the wheel to engage the tabs against a wheel hub aperture raised edge thereby resisting wheel cover removal.Type: GrantFiled: February 24, 2012Date of Patent: December 8, 2015Assignee: Cadillac Products Automotive CompanyInventors: Kevin E.

Patent number: 7935294Abstract: A system and method for operating an injection system to create a reduced density polymeric component uses a resin/blowing agent mixture, an injection molding machine having an injection molding screw positioned in a screw section, accumulators, a hydraulic pump, multiple molds, and a cooling system. Coolant is directed into each mold. The injection molding screw is rotated moving the mixture proximate to a receiving portion of the screw section. The injection molding screw is incrementally displaced to one of a plurality of successive injection positions each injecting a portion of the mixture into one of the molds by operating the hydraulic pump and discharging the accumulators. The accumulators are recharged after each injection molding screw displacement using the hydraulic pump. The injection molding screw is displaced and the accumulators recharged for each of the successive injection positions, each defining a stage for filling the molds in a single operating cycle of the injection system.Type: GrantFiled: March 29, 2006Date of Patent: May 3, 2011Assignee: Cadillac Products Automotive CompanyInventors: Robert J.

Patent number: 7240956Abstract: A vehicle moisture barrier comprises a formed barrier film and one or more bend flaps. The bend flaps may be bent along a bend axis formed by a deformation created at a junction line between the bend flap and the barrier film. The distal or free end of the bend flap contacts a trim panel to provide a stiffening force proximate to a raised rib extending from the opposite side of the barrier to promote sealing of the raised rib when a drawn form opposite to the raised rib is not provided to promote such sealing.Type: GrantFiled: August 8, 2005Date of Patent: July 10, 2007Assignee: Cadillac Products Automotive CompanyInventors: Andrew DeWolfe, Jack L Gray

Patent number: 7055887Abstract: A water and acoustic barrier positionable between a vehicle trim piece and a vehicle body member includes a sheet having a first layer formed of an interpolymer material and a second sheet layer formed of a polyethylene material. A raised rib is formed about at least a portion of a sheet perimeter. The raised rib having an adhesive bead forms a seal between the sheet and the vehicle body member. A raised form positioned adjacent the raised rib but oppositely oriented from the raised rib acts to substantially equalize a sealing pressure along the length of the raised rib. A plurality of apertures define fastener attachment points to connect the barrier to the vehicle trim piece.Type: GrantFiled: February 25, 2004Date of Patent: June 6, 2006Assignee: Cadillac Products Automotive CompanyInventors: Michael P Williams, II, Michael C Restaino, Andrew DeWolfe, Jeffrey R Masters, George L Bellairs
