1. A heating element for a surface component for forming an inner surface in a vehicle, the heating element comprising:
at least one film of an electrically conductive polymer material with a two-dimensionally formed electrical conductivity that provides a conductive surface area, and
at least two electrical conductors,
wherein the at least two electrical conductors are at least in certain portions spaced apart from one another and run in parallel to each other, maintaining an electric conduction to the electrically conductive polymer material such that electrical power can be applied to the electrically conductive polymer material two-dimensionally by way of the at least two conductors,
wherein each of the at least two electrical conductors are formed in more than one contact arm,
wherein the at least one film has a thickness of between 100 μm and 2000 μm, and
wherein the surface component is an interior panelling or a trim,
wherein the heating element comprises curvatures in two directions, the curvatures comprise a first curvature in a first direction and a second curvature in a second direction perpendicular to the first direction such that the heating element has a complex deformation that follows a 3D-form of the surface component.
