Appl. No.:

10/817025

Inventors:

Joseph Donatti - Howell MI, US
Andrew Mellentine - Owosso MI, US
Nelson Williams - Saline MI, US
Ian Williams - Howell MI, US

Assignee:

Lear Corporation - Southfield MI

International Classification:

B29C031/00

US Classification:

264240000, 264328200, 425103000

Abstract:

An apparatus for spraying polyurethane to form a skin on a mold. Polyurethane forming constituents are provided from a plurality of separate supply sources to separate recirculating fluid circuits. A mix head receives polyurethane constituents from the fluid circuits and mixes them to form a polyurethane mixture. A hydraulically operated valve controls the flow of the polyurethane constituents. The valve has a first position in which the polyurethane components are permitted to flow into the chamber of the mix head. The polyurethane mixture is then dispensed through a spray nozzle assembly. When the valve is in a second position, the polyurethane constituents are recirculated through the fluid circuits. A liquid solvent may be injected into the mix head under pressure to purge the mixture from the mix head and spray nozzle assembly in the second position.

International Classification:

A61F 5/00
B32B 3/26

US Classification:

428304400

Abstract:

The present invention provides a vehicle interior trim panel. The panel may be made by providing a spray mold having a mold surface having a cavity having a portion having a height to depth (H/D) ratio of less than 1.0. Polyurethane material can be sprayed proximate the surface of the tool to form a polyurethane skin layer. Expandable polyurethane material can be sprayed onto the skin layer to form a resilient layer. The skin layer and the resilient layer can be removed from the tool and positioning in a mold in a spaced apart relationship from a substrate, with a foam material being introduced between the substrate and the resilient layer to form a foam layer therebetween.

International Classification:

B05D 7/00
B05C 5/00

US Classification:

427421100, 521172000, 118300000

Abstract:

In at least one embodiment, the present invention relates to a method and system for making a composite polyurethane skin. In at least one embodiment, the method comprises providing a source of liquid polyol, providing a source of liquid isocyanate, providing a source of liquid low density foaming agent comprising blowing agent and low fogging surfactant, providing a spray mold tool having a mold surface, and providing a spraying device for spraying liquid material at the spray mold tool. The method further comprises, in at least one embodiment, directing polyol and isocyanate to the spraying device to form a polyurethane composition, spraying the polyurethane composition towards the spray mold tool to form a polyurethane skin layer on the spray mold tool, directing polyol, isocyanate and low density foaming agent to the spraying device to form an expandable polyurethane composition, and spraying the expandable polyurethane composition onto the skin layer to form a resilient expandable polyurethane layer on the skin.

International Classification:

B28B 1/32

US Classification:

264309000

Abstract:

The present invention relates a vehicle interior trim panel. In at least one embodiment, the panel may be made by providing a spray mold having a mold surface, spraying colored polyurethane material proximate the surface of the tool to form a colored polyurethane skin layer, and spraying expandable polyurethane material onto the skin layer to form a resilient layer on the colored polyurethane skin layer. The colored polyurethane skin layer and the resilient layer form a colored composite skin which can be removed from the tool and secured to a substrate to form a vehicle interior trim panel.

US Classification:

4283193, 264 455, 4284231, 4284233, 4284248

Abstract:

The invention relates to an interior panel component and the method for making the component. The interior panel component for use with a vehicle includes a skin layer, and a resilient layer secured to the skin. The resilient layer is made from a polymeric MDI, a pure MDI, and a polyol. The polyol is less than 50 pphr of a soy-based polyol. The resilient layer is secured to a substrate to form the interior panel component.
