LAMMERS ALEXANDER / LIND THOMAS

A method for introducing electric conductors into an overmolding of a steering wheel frame is provided. The electric conductors are used for heating and shielding purposes and for sensing contact on a steering wheel. In a first step, at least one cut is introduced into the overmolding using a cutting tool. In a second step, both a first layer of an electric conductor and a second layer of an electric conductor are simultaneously introduced into the cut that has been created. The first layer forms both a heating layer for heating the steering wheel and a guard layer which, together with the second layer acting as a sensor layer, allows the capacitive sensing of hand contact.
