A method of molding a plastic component having first and second portions interconnected by a transition zone with a barrier material encapsulated in the plastic material of both of the portions of the component. The permeable barrier material is placed in a mold cavity to divide the cavity into first and second portions. The first portion of the cavity is filled with plastic material while the second portion of the cavity is filled with plastic material to permeate the barrier material with plastic from both portions whereby the barrier material defines the transition zone and is encapsulated in the plastic component.

Molding method

An elongated energy-absorbing bumper assembly including energy-absorbing elastomeric or foam material extending between a rear mounting surface and a front impact surface with the material defining a hollow recess extending thereinto from the rear mounting surface and positioned between the ends of the assembly. The elastomeric foam material extends to the rear mounting surface at both ends of the hollow recess to define block-like end portions of the elastomeric material. A structural member extends between the block-like end portions of elastomeric material with the ends of the member embedded in the elastomeric foam material. The elastomeric material is the sole support and means of positioning the member so that the member is allowed unguided movement with the elastomeric material in multiple directions upon impact.

Multi-media energy absorbers (flex straddle)

A spring support is disposed about and fixed to a shock-absorbing unit and engages the lower end of a coil spring. A spring base engages the upper end of the coil spring and engages a mounting plate which is secured to the vehicle body and is also fixedly connected to the upper end of the shock absorber rod. The spring base has a cup-shaped cavity in which is disposed an energy-absorbing block of compressible elastomeric urethane-type material for absorbing energy when the shock absorber system bottoms out by the upper end of the shock-absorbing unit engaging the bottom of the elastomeric block. The energy-absorbing block has a peripheral disc portion extending thereabout and clamped between a dust cover and the spring base for securing the block in position. The energy-absorbing block includes a first plate of non-compressible material disposed between its upper face and the bottom of the cup-shaped cavity in the spring base. A second plate is disposed on the bottom face of the energy-absorbing block with a sound-deadening material disposed thereon for compressing the energy-absorbing block upon bottoming out of the system when the cylindrical energy-absorbing unit engages the bottom plate of the energy-absorbing block to compress the block.

Shock-absorbing assembly

A lightweight bumper guard assembly for a vehicle bumper including a flexible, decorative outer skin member of predetermined shape including a front wall, side walls and upper and lower walls for defining a cavity opening to the rear of the assembly, a core element located within the cavity of the outer skin member for supporting the outer skin member, the core element including a rear surface which generally conforms to the exterior of the vehicle bumper and is adapted to engage the vehicle bumper, the outer skin member including integral flanges extending inwardly across the opening of the cavity and overlapping the core element to hold the skin member tightly to the bumper.
