Abstract

The electric steering-wheel heating element to be mounted on a steering wheel rim has a linear center region made of flat ribbon-shaped, electrically conductive material. A first side region and a second side region made of flat ribbon-shaped, electrically conductive material each have at least one curved side segment and. The shape of the center region and of the curved side segments is configured such that, after mounting, the center region covers an external circumferential region of the steering wheel rim, the first side region alongside a longitudinal side of the center region covers a side circumferential region on one side of the steering wheel rim and the second side region alongside the other longitudinal side of the center region covers a side circumferential region on the other side of the steering wheel rim.
