Abstract
A three-dimensional heating element particularly intended for use in a steering-wheel. The three-dimensional heating element includes a heating composite having a heating element bonded between two films, one or both of which includes a heat shrinkable material. A covering material is placed over the heating composite. The film closest to the covering material includes a plastic material which forms a barrier preventing gaseous, liquid and/or solid chemicals from attacking the heating conductor when the heating element is applied to the steering-wheel. A foam material may be introduced in the space between the composite and covering material.
