1. A method of forming an electric heating/warming fabric article, the method comprising:
- configuring a sheet-form conductive layer element into an electrically conductive circuit pattern; and
attaching said circuit pattern to one of a first and a second broad surface of a fabric body for producing localized heating of the fabric body upon application of electrical current to said circuit pattern.

Abstract
Electric heating/warning composite fabric articles have at least a fabric layer having inner and outer surfaces, and an electric heating/warming element, formed, e.g., of die cut, conductive textile or plastic sheeting or metal foil, affixed at the inner surface of the fabric layer and adapted to generate heating/warming when connected to a power source. A barrier layer may be positioned, for example, adjacent to the inner surface of the fabric layer; e.g., with the electric heating/warming element formed thereupon, including to protect the electric circuit, e.g. against abrasion.

21. A heating/warming fabric article, comprising:
-
a fabric layer having an inner surface and an outer surface, and, attached to the inner surface of the fabric layer, a sheet-form conductive layer comprising a metallized sheet or a conductive textile including an electrically conductive circuit pattern for producing localized heating of the fabric article upon application of electrical current to said circuit pattern. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

42. A method of forming an electric heating/warming fabric article, the method comprising:
-
die-cutting a sheet-form conductive layer to form an electrically conductive circuit pattern wherein a first portion of the conductive layer is relatively narrower to increase localized heating and a second portion of the conductive layer is relatively wider to decrease localized heating;
attaching said circuit pattern to an outer surface of a fabric body;
incorporating the fabric body into an article of clothing; and
connecting a power source to the circuit pattern, thereby producing localized heating of the fabric body upon application of electrical current to said circuit pattern.
