Abstract

A new HEATED WINDSHIELD WIPER for melting snow and ice accumulation off of the windshield wipers of a vehicle. The inventive device includes a wiper arm having an elongate main articulation bow and a pair of elongate carrier bows each pivotally coupled to one of a pair of spaced apart a pivot mounts on the main articulation bow. The wiper arm also includes a wiper blade is mounted to the pair of carrier bows. A heating member having a elongate heating element and an elongate reflector is located between the pivot mounts of the main articulation bow so that the heating member is interposed between the main articulation bow and the wiper blade. The heating element is also spaced apart from the wiper blade so that the reflector is interposed between the main articulation bow and the heating element.

Claims

1. A heated windshield wiper, comprising:

a wiper arm having an elongate main articulation bow, a pair of elongate carrier bows, and an elongate wiper blade, said main articulation bow having a pair of spaced apart pivot mounts, a first of said carrier bows being pivotally coupled to a first of said pivot mounts, a second of said carrier bows being pivotally coupled to a second of said pivot mounts, said wiper blade being mounted to said pair of carrier bows;

a heating member having a elongate heating element, an elongate reflector and coupling means mounting said element and reflector on said main bow;

said reflector having an inner surface and an outer surface, said reflector being spaced apart from said heating element, said inner surface of said reflector facing said heating element;

said heating member being located between said pivot mounts of said main articulation bow, said heating member being interposed between said main articulation bow and said wiper blade, said heating element being spaced apart from said wiper blade, said reflector being interposed between said main articulation bow and said heating element; and

said inner surface of said reflector being for reflecting heat from the healing element towards said wiper blade.

2. The heated windshield wiper of claim 1, wherein said heating element is cylindrical.

3. The heated windshield wiper of claim 1, wherein said coupling means comprises a pair of mounting brackets, said mounting brackets of said heating member being coupled to said main articulation bow of said wiper arm.

4. The heated windshield wiper of claim 3, wherein said mounting brackets of said heating member are detachably coupled to said main articulation bow of said wiper arm.

5. The heated windshield wiper of claim 1, wherein said heating element is electrically coupled to a power source of a vehicle, and wherein said heating element provides heat sufficient to melt snow and ice on said wiper blade when powered.

6. The heated windshield wiper of claim 5, wherein said heating element has a coating for preventing electrical shorts when exposed to water.

7. The heated windshield wiper of claim 1, wherein said inner surface of said reflector is concave and said outer surface of said reflector is convex.

8. The heated windshield wiper of claim 7, wherein said reflector comprises aluminum.

9. A heated windshield wiper, comprising:

a wiper arm having an elongate main articulation bow, a pair of elongate carrier bows, and an elongate wiper blade, said main articulation bow having a pair of spaced apart pivot mounts, a first of said carrier bows being pivotally coupled to a first of said pivot mounts, a second of said carrier bows being pivotally coupled to a second of said pivot mounts, said wiper blade being mounted to said pair of carrier bows;

a heating member having a cylindrical elongate heating element, an elongate reflector, and a pair of mounting brackets engaged with said heating element and said reflector;

said heating element being electrically coupled to a power source of a vehicle;

said reflector having a concave inner surface and a convex outer surface, said reflector being spaced apart from said heating element, said concave inner surface of said reflector facing said heating element;

said heating member being located between said pivot mounts of said main articulation bow, said heating member being interposed between said main articulation bow and said wiper blade, said heating element being spaced apart from said wiper blade, said reflector being interposed between said main articulation bow and said heating element;

said mounting brackets of said heating member being detachably coupled to said main articulation bow of said wiper arm; and

said heating element providing heat sufficient to melt snow and ice on said wiper blade when powered, said concave inner surface of said reflector being for reflecting heat towards said wiper blade, said reflector comprising aluminum.
