Abstract: A multilayer window guiderail is disclosed. The window guiderail includes a rail portion having an outer edge, a rail surface and an opposing rear surface. The rail portion includes a core and an integral rail cover layer disposed on the core. The core includes a first polymer material and the rail cover layer includes a second polymer material. An apparatus for making a multilayer guiderail includes a plurality of die portions having respective cavity portions. The cavity portions are configured to define a die cavity having the shape of the guiderail, at least one of the die portions being a slidable die portion and at least one of the die portions being a fixed die portion. The parting surface of the slidable die portion is configured for sliding translation of its parting surface over the parting surface of the fixed die portion along a translation path.

Abstract: A multiple layer trim door module for a vehicle door is provided, the multiple layer trim door module having: a separately formed structural member having at least one column and at least one bar crossing each other to form a structural space frame grid, wherein the separately formed structural member is formed by a plastic molding process wherein the at least one column and at least one bar have a first structural rigidity associated therewith; a separately formed trim back plate with reduced structural properties attached to the structural member, wherein the separately formed trim back plate is formed by a plastic molding process and the separately formed trim back plate has a second structural rigidity associated therewith, the second structural rigidity being less than the first structural rigidity; and door trim with reduced structural properties attached to trim back plate.
