Attorney, Agent or FirmInternational ClassH05B 003/34AbstractA fabric article that generates heat upon application of electrical power is formed, for example, by knitting or weaving, to form a fabric prebody. An electrical resistance heating element in the form of a conductive yarn is incorporated into the fabric prebody, the electrical resistance heating elements extending between opposite edge regions of the fabric. Conductive elements are provided for connecting the electrical resistance heating elements to a source of electrical power.Field of SearchApparelBed covering (e.g., blanket) Static structure (e.g., building pavement, etc.) Body-supported (e.g., human body) Flexible or resilient (e.g., warming pad) Cloth or other fabric With resistive-element attaching, securing or electrical insulation means Comprising coating printed or deposited on core sheath or support means Resistive element interwoven with fabric support Flexible Heating element structure Articles Garments Incorporated unknitted materials Fleece or pile type Warp Fleece or pile type Warp Differential pile length or surface | |
