Abstract: A seat air-conditioner is applied for a seat on which an occupant is seated. The seat air-conditioner includes a blower configured to suck air through a supporting surface of the seat that supports the occupant, and an introducing passage through which the air is introduced from the supporting surface to the blower. The seat includes a seat cushion supporting a lower body of the occupant and a seat back supporting an upper body of the occupant. The blower is disposed in the seat back such that airflow generated by the blower flows more through the seat back than through the seat cushion.

Abstract: A seat air conditioner includes an air passage that is disposed in a seat of the vehicle, a blower that blows air into the air passage, an outlet through which the air flowing through the air passage is blown as a blown air toward a rear side of a vehicle interior along an upper surface of the seat, and a guide member that is disposed behind the outlet to be moveable between a first position and a second position. The guide member allows the blown air from the outlet to flow toward the rear side of the vehicle interior together with a surrounding air entangled by the blown air when the guide member is at the first position and guides the blown air from the outlet toward a ceiling side or a floor side of the vehicle interior when the guide member is at the second position. The guide member is retracted into a housing space defined in the seat when the guide member is at the first position. At least a portion of the guide member protrudes upward from the upper surface of the seat when the guide member is at the second position.

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.

Abstract: A seat air conditioner includes a ventilation passage member disposed on a surface of a seat cushion and configured to form an air flow passage through which an air flows in a predetermined direction along the surface. The ventilation passage member includes a first ventilation port and a second ventilation port through which an inside of the air flow passage communicates with outside of the air flow passage. The ventilation passage member is provided to close communication between the inside and outside of the air flow passage, over an entire region of the ventilation passage member between the first ventilation port and the second ventilation port in the predetermined direction.

Abstract: A seat air-conditioning device includes a seat pad, a back lid and a blower. The back lid covers an opening side of a ventilation groove of the seat pad. The blower generates an airflow in a ventilation passage which is defined by the ventilation groove and the back lid. The back lid has a communication port that is formed at an opposing region of the back lid, which is opposed to the blower. The communication port is configured to conduct the airflow generated by the blower. The seat pad has a plurality of support portions that contact the back lid and are formed at an overlapping region of the seat pad which overlaps with the opposing region in a thickness direction of the seat pad. The support portions are circumferentially arranged one after another around the communication port.
