Abstract
Electric heating/warming composite fabric articles have at least a fabric layer having inner and outer surfaces, and an electric heating/warming element, e.g., including a bus, formed, e.g., of die cut, metallized 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.

30. 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 including a bus, 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. - View Dependent Claims (31, 32)

33. 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 at least one 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. - View Dependent Claims (34, 35, 36)

37. A method of forming an electric heating/warming fabric article, the method comprising:
-
configuring a planar, sheet-form conductive layer element, formed of materials selected from the group consisting of metallized textiles, metallized plastic sheeting, and metal foils, into an electrically conductive circuit of heating elements and buses, the buses being formed integrally with the heating elements, the electrically conductive circuit having a predetermined shape corresponding to a selected surface region of a wearer'"'"'s body and with one or more predetermined circuit regions of relatively higher resistivity among one or more circuit regions of relatively lower resistivity, the one or more circuit regions of relatively higher resistivity being positioned for correlation with one or more selected heating regions of the wearer'"'"'s body; attaching the circuit to one of a first broad surface and a second broad surface of a fabric body in an arrangement corresponding to the selected surface region and in correlation with the one or more selected heating regions; and
,upon application of electrical current to the circuit, producing localized heating in the one or more predetermined circuit regions of relatively higher resistivity of the circuit attached upon the fabric body for preferential heating of the one or more selected heating regions of the wearer'"'"'s body. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62)
