A process for in-molding an energy-absorbing countermeasure to a headliner 18 for use in a vehicle, plus the intermediate and final assemblies formed by the process. The process includes the steps of (1) preparing a sheet; (1A) optionally affixing to the sheet a means for adhering to form a composite sheet; (2) thermoforming the composite sheet into a composite energy-absorbing countermeasure; (3) preparing a headliner layup (including optionally a means for adhering, a headliner core, and a cover stock) before forming a bond between the headliner layup and the composite energy-absorbing countermeasure. The assembly thus includes the energy-absorbing countermeasure 22 and a means for adhering it to the headliner core 18. |

A method of deforming a component includes the step of forming the component from thermosetting, elastomeric microcellular polyurethane. The method further includes the step of heating at least a first portion of the component to a first temperature. The method further includes the step of compressing the first portion of the component while maintaining the first portion at the first temperature and while maintaining the second portion of the component at an undeformable state. The method of deforming the component shapes the first portion of the component. Preferably the method shapes the first portion of the component into a thin and/or complexly shape. The method of deforming the component also increases the first portion of the component relative to the second portion of the component, i.e. to densifying the component such that the component has varying density. |

The invention is to permit a bushing main body of rubber elastomer to be adhered to a bar member while retaining a necessary contact pressure for adhering and after adhering, to permit a further compressive force to be imparted. The bushing main body (10) having a bore (11), through which the bar member (B) passes, and a bracket (20) holding the former are longitudinally split into two, respectively, the resulting split rubber bodies (10a)(10b) are vulcanization bonded to inner peripheral surfaces of the resulting half bracket members (20a)(20b). The inside diameter (D1) of both split rubber bodies as molded is made smaller than the outside diameter (D2) of the bar member, and inner peripheral surfaces (11a)(11b) at the bore are formed to be eccentric on mutually opposite sides. While pinching the bar member by both split rubber bodies, both half bracket members interposing a spacer (30) are locked together to compress the split rubber bodies thereby to adhere the peripheral surfaces at the bore to the outer peripheral surface of the bar member, and after the spacer is removed, both half members are locked so as to butt contact with each other thereby further compressing both split rubber bodies in mutually opposing directions. |

A vulcanization mold (2) includes several segments (8a, 8b; 10a, 10b; 12a, 12b; 14a, 14b) which define two end profiles (8, 10) and two inner profile shells (12, 14) having concave surfaces. With synchronous movement sequences, which take place via linear controls from both ends, the segments (8a, 8b; 10a, 10b; 12a, 12b; 14a, 14b) are moved together under simultaneous shaping pressure. The outer profile shells (8, 10) pass through twice the distance as the inner profile shells (12, 14). The forming of the work blank (20) is completed via the shaping pressure when the mold (2) has reached the closed position. Preferably the upper profile half shells (8a, 10a, 12a, 14a) and the lower profile segments (8b, 10b, 12b, 14b) are operatively connected to each other via toothed racks (40a, 46a, 48a, 54a; 40b, 46b, 48b, 54b) and gear wheels (42a, 44a, 50a, 52a; 42b, 44b, 50b, 52b) including additional sets of teeth (42a′, 50a′; 42b′, 50b′). |

Thermosetting and thermoplastic elastomers are provided having magnetic filler packed within the elastomeric matrix and capable of being aligned and energized, before, during or after the molding of the elastomer. The magnetically-filled elastomers therefore provide useful permanent magnetic fields which being physically soft. The magnetic filler is aligned within the elastomeric matrix and energized by subjecting the magnetically-filled elastomer to magnetic energy before, during and/or after molding of the magnetically-filled elastomer. A particularly preferred magnetically-filled elastomer is a magnetically-filled polyurethane elastomer composition wherein the elastomer is the reaction product of a urethane-forming compound having at least two urethane-forming reactive sites, an elasticizing diol or triol, and a diisocyanate reacted in less than stoiciometric amounts to allow for the formation of urethane linkages involving less than about 85% of the urethane-forming reactive sites.

An apparatus for heating a rubber-metal plate composite formed of a plurality of unvulcanized rubber layers and metal plates, each being overlaid alternately, by induction heating, includes an induction coil for applying a magnetic field to the composite and heating the metal plates due to eddy currents generated by the magnetic field, a power unit for applying an alternating current to the induction coil to generate the magnetic field, and a mold to confine the periphery of the composite. The mold is made of a nonmagnetic or weakly magnetic material with electrical conductivity, such as austenitic stainless steel. The mold generates enough heat to function as the heating unit by generating eddy currents in the conductive mold while magnetic flux permeates the mold substantially without loss and reaches the composite therein. |
