Abstract

A heatable steering wheel includes a steering wheel blank, a heating mat wrapped around the steering wheel blank, a first, visible hard sheathing whose surface is refinished after having been installed, a second, visible softer sheathing, both of the sheathings abutting each other in an abutting area, and a coupling element in the abutting area. The coupling element, as seen from the outside, has a depression and that, starting from the first sheathing, extends under the abutting area all the way to an abutting edge of the second sheathing. The heating mat extends continuously under the first sheathing and under the coupling element all the way to under the second sheathing.
