Electric heating/warming fabric articles

A method of forming an electric heating/warming fabric article, the method comprising:

• configuring a planar, sheet-form conductive layer element, formed of electrically conductive material selected from the group consisting of metallized textile, metallized plastic sheeting, and metal foil, into an electrically conductive circuit with shape corresponding to a selected surface region of a wearer's body and with one or more 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 positioned for correlation with one or more selected heating regions of the wearer's body;
• attaching said circuit to at least 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;
• attached a bus in communication with said circuit;
• and,
• upon application of electrical current through said bus to said circuit, producing localized heating in the one or more 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.

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 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 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, thereby producing localized heating of the fabric body upon application of electrical current to said circuit.
