Abstract
A method of introducing an electric conductor (22), especially a heating wire, into foam padding (20) of a steering wheel skeleton (18) includes introducing at least one cut (26) into the foam padding (20) by means of a cutting tool (34). At the same time the conductor is introduced into the produced cut (26). Moreover a tool as well as a tool assembly for implementing the method and a vehicle steering wheel are provided.
Claims31
A method of introducing an electric conductor (22), especially a heating wire, into foam padding (20) of a steering wheel skeleton (18) comprising the following steps of:
- introducing at least one cut (26) into the foam padding (20) by means of a cutting tool (34) during a first method step, and
- at the same time introducing the electric conductor (22) into the produced cut (26) during a second method step.
A vehicle steering wheel (10) comprising a steering wheel skeleton (18), a steering wheel rim (14) foam-padded by foam padding (20) and an electric conductor (22), wherein a cut (26) within which the electric conductor (22) is located is introduced to the foam padding (20).
