摘要： An interior energy absorbing panel for the passenger compartment of a motor vehicle has a thermoplastic skin, a thermoplastic retainer, a thermoplastic air duct, and an energy absorbing rigid polyurethane foam core which is reaction injection molded about the air duct and to the skin and retainer without requiring any added adhesive. When the skin is of the soft type, a layer of semirigid polyurethane foam is reaction injection molded between the skin and the energy absorbing foam core to impart a soft feel to the skin and protect the energy absorbing foam core from indentation during normal use.

摘要： A cover for an inflatable air bag housing is formed of integrally molded resinous plastic material and defined therein is a hinge area and a thin fracture line forming a door which pivots to an open position upon fracture of the cover along the fracture line when an air bag is inflated. A metal reinforcing element is embedded in the resinous plastic material and includes segments diverging and below the hinge area forming an open space or void which is filled in with a low density collapsible, energy absorbing, rigid foam which exhibits minimal spring back. The filler helps prevent sagging or read-through of the cover above the void when prolonged exposure to heat and sun is experienced. Moreover, the foam filler absorbs energy during bag deployment and aids in preventing plastic resin from leaking into the void space during the initial fabrication of the cover as the metal reinforcement element is molded in place.
摘要翻译：用于可充气气囊壳体的盖由一体模制的树脂塑料材料形成，并且其中限定有铰链区域和薄的断裂线，其形成门，当气囊在气囊充气金属增强元件嵌入在树脂塑料材料中，并且包括在铰链区域的下方和下方形成的开口空间或空隙的段，其填充有表现出最小回弹的低密度可收缩，能量吸收的刚性泡沫。当长时间暴露于热和阳光下时，填料有助于防止在空隙上方的凹陷的下垂或透视。此外，泡沫填料在袋展开期间吸收能量，并且有助于在金属加固元件被模制就位时在盖的初始制造期间防止塑料树脂泄漏到空隙空间中。

摘要： An interior trim component, such as a door panel, having an outer skin backed by a low density molded mat foam substrate and an energy absorbing foam backing is manufactured in a single mold tool in a multiple stage foaming operation in which the outer skin and a glass reinforcement mat are positioned in the mold cavity and a mold insert corresponding to the energy absorbing foam layer is mounted to the lid of the mold tool. A polyurethane precursor mixture is poured into the open mold and the lid closed to generate the low density molded mat substrate. The mold is opened and the mold insert removed and a second urethane precursor mixture is poured onto the substrate and the mold closed to generate the energy absorbing foam backing within the space of the mold cavity previously occupied by the mold insert.

摘要： A solvent flush reaction injection molding mixhead has a mixing chamber with a solvent inlet port in one end and a chemical outlet port in an opposite end. A pair of hydraulically operated chemical injectors are connected to the mixing chamber between the solvent inlet port and chemical outlet port to inject liquid reaction molding chemicals at high pressure through injector ports into the mixing chamber. The mixed chemicals are delivered through the chemical outlet port to a spray wand on the mixhead for application to a mold surface or an object requiring a foam coating. A flush valve is associated with the solvent inlet port and is moveable from a closed position to block the solvent inlet port while the chemicals are injected into the mixing chamber, and an open position where liquid solvent under a high pressure is supplied through turbulator ports into the mixing chamber to clean and flush any remaining mixed chemicals from the flush valve, the mixing chamber including the chemical injector ports, and the spray wand.
