Patent ID: 8431868

Claim:
A thermally regulated electrical deicing apparatus arranged for securement adjacent an exterior portion of a vehicular windshield comprising: a flexible cover portion with a top edge spaced from a bottom edge and side edges respectfully extending between said top and bottom edges; a securement means, attached to a front cover face of said flexible cover portion, for attachment of said flexible cover portion adjacent an exterior portion of said windshield; and an electrical deicing element in direct contact with said windshield and supported by a rear cover face of said flexible cover portion provides energy during deicing of said windshield exterior portion, in which said electrical deicing element comprises: a male alternating current electrical plug, which when connected to an alternating current voltage source, conducts voltage to a single heating element through an electrical power supply line; and a thermistor interposed in series between said male plug and said single heating element directly controlling the voltage conducted to the single heating element without the aid of additional devices, and in which said thermistor connected in series with said heating element together form a parallel connection with said electrical power supply line, the electrical power supply line including at least a female alternating current electrical plug, an electrically “hot” low resistance, minimal heat generating conductor running continuously physically parallel and adjacent said electrical deicing element and between said male alternating current electrical plug and said female alternating current electrical plug to assure alternating current voltage is available at said female alternating current electrical plug when said male alternating current electrical plug is connected to said alternating current voltage source independent of voltage flow through said electrical deicing element, and wherein alternating current voltage must be present in said electrically “hot” low resistance, minimal heat generating conductor for voltage to flow through said electrical deicing element.
