Abstract
Electric heaters and blower units are disposed inside an occupant seat having exterior cover members, each of which has a plurality of outlet openings. Each electric heater heats the corresponding exterior cover member, and each blower unit blows air through the outlet openings of the corresponding cover member. Manipulation dials are provided to manipulate the corresponding electric heaters and blower units. A variable heating power command signal, which commands increasing or decreasing of a heating power of each corresponding electric heater, and a variable flow rate command signal, which commands increasing or decreasing of an air flow rate of each corresponding blower unit, are generated through adjustment manipulation of the manipulation dial in synchronism with movement of the manipulation dial.
