  • Patent number: 5787543
    Abstract: A windshield wiper blade having an internal conduit extending throughout the length of the wiper blade body through which an electric heating element is placed provides a means to address a wintertime problem of windshield wiper icing and freeze-up causing the wiper blade to lose flexibility and not sweep the curved windshield commonly found on most motor vehicles clear enough for good driving visibility. The preferred means to address this problem is to provide an electrical heat element within the wiper blade body of about the same linear length as the wiper blade body. Additionally, in the present invention, a low-cost resistance wire type heat element that can be cut to accommodate various wiper blade lengths is used. The heat element comprises a flexible spiraled resistance wire coiled around stranded fiberglass, the whole of which is encapsulated in a silicone rubber jacket.
