The invention relates to a heatable touch sensor and a steering wheel. It has an optical waveguide which is connected to an electrical heat conductor. The optical waveguide changes its transmission behavior, which is determined, with a change in position or bending. The heat conductor is a resistance heater which emits heat by applying an electrical voltage and by the associated current flow. The touch sensor operates by means of optical interferometry, which enables a very high sensing accuracy.

Heatable touch sensor and steering wheel having such a touch sensor

A method for producing a covered steering wheel for a vehicle. A steering wheel skeleton is overmolded with a matrix material. A covering material is coated on its non-visible side with an activatable material. The coated covering material is applied to the overmolded steering wheel skeleton so that its non-visible side faces the overmolded steering wheel skeleton. Longitudinal edges of the covering material are joined together. The activatable material is activated with creation of an integral connection between the covering material and the matrix material.
