SUMMARY OF THE INVENTION The present invention is a method for manufacturing a steering wheel having a tear line for an airbag cover, a steering wheel rim, a steering wheel spoke, and a seamless cover surrounding a central region. About. The cover has a plastic molded part made as a single piece by casting or injection molding, with a closed surface and an optional foam base element. The method according to the invention is characterized in that a core of a material having a low melting point is mounted on the central base of the steering wheel skeleton. The steering wheel skeleton and core are then placed in a mold to produce a plastic molded part. A plastic molded part is formed. After the plastic molding has hardened, the core is melted by increasing the temperature and the material is removed from the plastic molding in liquid form. |
