Abstract

A heating-element-embedded material has a lateral heating element (1) embedded in furniture material (2) which can be used for covering seats and other furniture and for making heating articles of furniture (3). The lateral heating element has series-parallel heating-resistor conveyance of current from an input terminal (4) to a return terminal (5). The lateral heating element can include a resistance-wire net (14), a thin sheet (20), a plurality of parallel thin strips (22), a plurality of parallel thin lines (23), a plurality of parallel expanded helical or zigzag lines (24), a plurality of parallel thin zigzag strips (25) or other generally series-parallel conveyance within or on either side of the furniture material. The furniture material can be rubberlike, leatherlike, vinyl-like, cloth-like, smooth, rough, moisture-proof, permeable, impermeable or made otherwise for heated-surface use. Heating-article uses can include heating pads (17), seat covers (26), pillow covers (27), quilts (28), mattress covers (29) and wall covers (30).
