A wiper blade selectively mounts on the free end of the wiper arm having a resilient wiper element arranged to slidably receive a heating element therein. A connector selectively mounts the heating element and an associated thermostat to an electrical supply of the system enabling the thermostat and heating element to be replaced independently of the wiper blade. When more that one wiper blade is provided, the respective heating elements preferably have lengths which correspond to the length of the respective wiper elements within which they are mounted. When the heating elements are of different length, a longest one of the heating elements preferably has a lower electrical resistance per unit length thereof than a shortest one of the heating elements. Total electrical resistances of the respective heating elements may thus be substantially equal.

    Abstract: The present invention relates to an apparatus for activating heat conductive wires by detecting a rotating angle of a wiper arm, wherein said heat conductive wires installed on the both side of a wiper blade are activated when the detected rotating angle is smaller than a predetermined angle, so that the accumulated snow is melted away due to the heat emitted from said heat conductive wires.

  • Patent number: 6236019
    Abstract: A heated windshield wiper assembly is provided which is attachable to the wiper blade carrier arm of a vehicle. The assembly has a wiper blade having an electrical heating element throughout its longitudinal length. The heating element is energized through a thermo-sensor that is activated at a selected temperature and upon oscillation of the wiper arm.
