Abstract
A heated windshield wiper system for reducing the accumulation of ice and snow upon a vehicle'"'"'s windshield wipers during cold weather conditions. The inventive device includes a blade member having a passageway extending through a central portion thereof, a heating element removably positioned within the passageway, an electronic control circuit electrically connected to the heating element for controlling the heating element, a plurality of arm photovoltaic cells attached to the wiper arm and electrically connected to the electronic control circuit, and a plurality of frame photovoltaic cells attached to the wiper frame and electrically connected to the electronic control circuit. The electronic control circuit includes a battery within for providing electrical power to the heating element during darkness. The electronic control circuit may also include an electrical connection to the vehicle'"'"'s power system. An activation indicator is connected to the electronic control circuit for visually indicating to the driver when the heating element is receiving electrical power. A pair of electrical connectors are electrically connectable together thereby releasably electrically connecting the electronic control circuit to the heating element allowing the heating element to be replaced. A thermostat within the electronic control circuit activates and deactivates the heating element depending upon the outside air temperature.
