Zusammenfassung: | A heater device for heating an user's body seated on a seat includes a heat generating portion that is arranged in a recess recessed from a surface of the seat, and generates heat by energization, a distance detection unit that detects a distance between an object around the heat generating portion and the heat generating portion, and a control unit that controls energization of the heat generating portion. A first control portion controls energization amount of the heat generating portion so that the output of the heat generating portion becomes equal to or higher than a predetermined output, when the distance is longer than an offset distance between the heat generating portion and the surface of the seat. A second control portion controls the energization amount so that the output becomes less than the predetermined output, when the distance is equal to or less than the offset distance. |
