ABSTRACT:
An electrically heated windshield wiper assembly which includes a wiper blade of a resilient material such as rubber which is mounted within a wiper blade mounting strip of metallic material coated or laminated with plastic wherein the material is electrically resistant metal which generates heat therein responsive to electrical current being passed therethrough in a such a manner that this heat will warm the wiper blade to facilitate efficiency of wiping thereof of a conventional windshield configuration. The wiper blade mounting strip also provides the means whereby the wiper blade is secured to the clips of a conventional wiper frame. The wiper blade mounting strip defines a slot longitudinally along the center thereof into which the wiper blade is detachably secured. A rheostat is included to vary the amount of current and therefore the amount of heating of the wiper blade mounting strip and a switch is included for selective operation of the heating system. For control of the amount of heating a timer may also be included in series with the above electrical elements.
