System Outline

The system sends the cool or warm air from the seat surface to ease the warmth, coldness or stuffy feelings on the seat, which the passengers may feel.

By operating the climate control seat SW, the air is sent to seat cushion and seat back from the fan installed under the seat. The air is heated or cooled by the Peltier element installed on the back on the pad of the seat cushion and seat back, and is sent to the seat surface.

And by operating the climate control seat SW, the quantity of the air can be adjusted among three levels for cooled heated, three levels for heated air and the ventilation mode. When the maximum cooled air is sent, the quantity of the air falls one level after the 15 minutes from the operation.
