Patent ID: 7268320

Claim:
A heating/warming fabric article, comprising: a fabric layer having a broad first surface and a broad second surface, and, attached to at least one of the broad first surface and the broad second surface, a planar, sheet-form conductive layer element, formed of material selected from the group consisting of metallized textile, metallized plastic sheeting, and metal foil, formed 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, the sheet-form conductive layer element, upon application of electrical current to said circuit, producing localized heating in the one or more circuit regions of relatively higher resistivity of the circuit attached upon the fabric layer for preferential heating of the one or more selected heating regions of the wearer's body.
