Abstract:
A seat air conditioning system for a vehicle occupant seat that is placed in a passenger room of a vehicle and includes at least one exterior cover member, which forms an occupant contacting surface of the seat for contacting with a vehicle occupant and has a plurality of outlet openings penetrating through the exterior cover member, the seat air conditioning system comprising:at least one electric heater disposed inside the seat, wherein each electric heater heats a corresponding one of the at least one exterior cover member of the seat; at least one blower unit disposed inside the seat, wherein each blower unit blows air through the outlet openings of a corresponding one of the at least one exterior cover member; a single manipulating means for manipulating the at least one electric heater and the at least one blower unit; an air flow rate command signal generating means for outputting the air flow rate command signal; and a heating power command signal generating means for outputting the heating power command signal, wherein: the single manipulating means is disposed inside the passenger room and is manually manipulatable; 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 single manipulating means in synchronism with movement of the single manipulating means; the air flow rate command signal generating means and the heating power command signal generating means are arranged adjacent to each other within a movable range of the manipulating means and are placed in two different imaginary planes, respectively; and the air flow rate command signal of the air flow rate command signal generating means and the heating power command signal of the heating power command signal generating means are varied in synchronism with positional change of the manipulating means within the movable range of the manipulating means.
