Abstract: A seat air-conditioning device is applied to a seat and includes a cushion material, an outer cover, a ventilation hole and a surface groove. The cushion material supports a back or buttocks of an occupant seated on the seat. The outer cover covers the cushion material and has perforation holes. The ventilation hole is formed at a portion of the cushion material opposed to the back or the buttocks of the occupant seated on the seat. The ventilation hole is configured to suction or blow air. The surface groove is formed at a portion of the cushion material which is adjacent to the outer cover. The surface groove is communicated with the ventilation hole and extends from the ventilation hole in a direction away from a location of the cushion material, at which a center of the back or a center of the buttocks of the occupant is placed.

Abstract: A seat air-conditioner includes an inlet portion, a blower, and a door device. The inlet portion is disposed inside a seat and defines a first inlet and a second inlet. The blower is disposed inside the seat. The door device is configured to be moved to open the first inlet while closing the second inlet and to close the first inlet while opening the second inlet. The first inlet is arranged such that an air drawn into the seat through a passenger supporting portion of the seat is drawn into the blower through the first inlet. The second inlet is arranged such that an air drawn into the seat through a portion of the seat other than the passenger supporting portion is more likely to be drawn into the second inlet than into the first inlet.
