A heating device for a seat exhibiting excellent durability, reliability, safety and enhanced workability in fixing work to a seat while reducing the cost and weight and ensuring comfortable feeling at seating without causing a strange feeling. The heating device for a seat comprises a heating matter (4) consisting of a substrate (2) and a cord-like heater (3) arranged on the substrate, an element (5) for detecting the temperature of the heating matter, and a circuit (1) for controlling the temperature of the heating matter based on the output from the temperature detection element, characterized in that the temperature detection element and the temperature control circuit are arranged at predetermined positions of the substrate. The temperature control circuit is insulation-coated together with a part of lead wires connected with the temperature control circuit.
L~invention concerne un dispositif chauffant pour un siège, particulièrement durable, fiable et sûr, susceptible d~être facilement monté sur le siège, de coût et de poids réduits et ne provoquant aucune gêne en position assise. Le dispositif chauffant comprend une matière chauffante (4) comportant un substrat (2) et un filament chauffant (3) disposé sur le substrat, un élément de détection de température (5) servant à détecter la température de la matière chauffante, et un circuit de régulation de température (1) servant à réguler la température de la matière chauffante en fonction d~un signal fourni par l~élément de détection de température. Le dispositif chauffant est caractérisé en ce que l~élément de détection de température et le circuit de régulation de température sont placés dans des positions prédéterminées sur le substrat. Le circuit de régulation de température ainsi qu~une partie de ses fils de sortie sont revêtus d~un isolant.
