Abstract
Abstract The disclosure provides for the construction of electrically heated panels and a method of manufacturing wearing apparel incorporating such panels for operation by a portable power supply. The panels are constructed by attaching parallel electrodes to a flexible electrically conductive resistance element formed by a coating of polymer containing carbon on textile material. The electrodes being in the form of tinned braided electrical conductors stitched to the textile material by an axial row of stitches through the braided conductor. In one embodiment the polymer coating is applied to the textile material before the electrodes are attached thereto while in an alternative embodiment the polymer coating is applied after the braided conductor is secured to the textile material. The method of connecting the conductor to the coating provides for good electrical conductivity.

Claim 1
Independent Claim
117 words
A method of forming electrical heating panels comprising coating a blank of textile material with an electrically conductive polymer to form a flexible electrically conductive resistance element, arranging two continuous electrodes of braided elecTrical conductor on said element, a major portion of one of said electrodes being in spaced parallel relation to a major portion of the other electrode, said electrodes arranged sinuously to form electrically conductive paths between said electrodes and over a major portion of the element, securing said electrodes to said element by means of an axial row of stitches through each electrode, and electrically isolating the electrodes from one another where they cross or lie adjacent one another by strips of insulating material.
Claim 2
Independent Claim
117 words
A method of forming electrical heating panels comprising coating a blank of textile material with an electrically conductive polymer to form a flexible electrically conductive resistance element, arranging two continuous electrodes of braided elecTrical conductor on said element, a major portion of one of said electrodes being in spaced parallel relation to a major portion of the other electrode, said electrodes arranged sinuously to form electrically conductive paths between said electrodes and over a major portion of the element, securing said electrodes to said element by means of an axial row of stitches through each electrode, and electrically isolating the electrodes from one another where they cross or lie adjacent one another by strips of insulating material.
Claim 3
Independent Claim
125 words
A method of forming electrical heating panels comprising the steps of arranging two continuous electrodes of braided electrical conductor on a blank of textile material, said electrodes arranged sinuously with a major portion of one of said electrodes in spaced parallel relation to a major portion of the other electrode, securing said electrodes to said blank by means of an axial row of stitches through each electrode, isolating said electrodes from one another where they cross or lie adjacent one another by strips of insulating material stitched to the blank and coating said blank and electrodes with electrically conductive polymer to form a flexible electrically conductive resistance element and to provide electrically conductive paths between said electrodes and over a major portion of said blank.
