Heatable wooden steering wheel

摘要

The surface layer of wood veneer (1) is separated from the heating wires (3) by a layer (2) of high thermal conductivity, which can be a glass fiber reinforced plastic with a filler material of high thermal conductivity. The conductive layer and the veneer surface are prepared as two half casings and are secured to the rim (6) with adhesive. The half-casings can have an inner layer, e.g. of wood veneer, to improve the strength of the adhesive joint.
