A heated wiper arrangement for windshields and like surfaces including an elongated backing member having means along the inner face area thereof to retainingly receive an elongated wiper blade longitudinally therealong. A heating element is closely associated with the backing member at generally the neutral surface or plane thereof for heating the wiper blade by conduction. Location of the heating element at generally the backing member neutral surface or plane prevents stresses from being applied to the element during bending of the backing member for accommodating the windshield surface contour. The heating element may be advantageously located generally along the backing member longitudinal neutral or moment of inertia axis as well as at locations spaced laterally outward therefrom in the neutral surface. Means may also be advantageously provided for protecting the heating element from natural and other corrosive elements.
