WARMING DEVICE AND VEHICLE SEAT

PROBLEM TO BE SOLVED: To provide a warming device capable of performing an accurate and positive detection and control of temperature.SOLUTION: This invention relates to a warming device comprising a base material, a heat generating line and a temperature detecting line in which the heat generating line and the temperature detecting line are arranged on the base material, the temperature detecting line is a single line, the temperature detecting line and the heat generating line, the temperature detecting lines themselves and the heat generating lines themselves are arranged so as not to be crossed to each other, the heat generating line has some portions where they are arranged in zig-zag form, and the temperature detecting lines are arranged in a zig-zag form so as to enter every one of a plurality of zig-zag forms. This invention also relates to a warming device in which the heat generating lines are arranged in a zig-zag form and constitute a plurality of parallel circuits and the temperature detecting line is arranged in a zig-zag form while being entered between one parallel circuit at the heat generating line and another parallel circuit. This invention relates to a vehicle seat having a skin and a pad and each of the aforesaid warming devices is arranged between the skin and the pad. 【課題】温度の検知と制御を正確且つ確実に行うことが可能な採暖装置を提供すること。【解決手段】基材と、発熱線と、温度検知線を有し、上記発熱線及び上記温度検知線が上記基材上に配設されており、上記温度検知線が単線であり、上記温度検知線と上記発熱線、上記温度検知線同士、及び、上記発熱線同士が交差しないように配設されており、上記発熱線が蛇行形状で配設されている部分を有し、上記発熱線における複数の蛇行形状おきに入り込むようにして上記温度検知線が蛇行形状で配設されている採暖装置。上記発熱線が蛇行形状で配設されているとともに、複数の並列回路を構成しており、上記発熱線における１つの並列回路ともう１つの並列回路の間に入り込むようにして上記温度検知線が蛇行形状で配設されている採暖装置。表皮とパットを有し、上記表皮と上記パットの間に上記の採暖装置が配置された車両用座席。【選択図】 図１
