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.

Seat air-conditioner

A seat air-conditioning device provided in a compartment of a vehicle that supplies air generated by a blower includes a pad wrapped in the skin and a ventilation sheet which is formed in a thin plate shape and supplies air to the seated passenger. An internal space is formed in the pad. The pad includes a seating side communication part that communicates the internal space with the seating surface of the skin, and a blower side communication portion that communicates the internal space with the blower. The ventilation sheet is disposed in the internal space.

Seat air-conditioning device

A seat air conditioner is applied to a seat including a seat cushion portion, a seat back portion, and a reclining mechanism portion for varying a reclining angle of the seat back portion relative to the seat cushion portion. The seat air conditioner includes a blower, an air blowing portion from which the air blown by the blower is blown toward the seated occupant, and a wind direction adjustment unit that adjusts a wind direction of the blown air. The wind direction adjustment unit is configured to adjust the wind direction of the air blown out from at least the part of the air blowing portion such that the air from the air blowing portion is blown toward a specific part of the seated occupant regardless of the reclining angle when the seat back portion is inclined toward a rear side of the seat.

Seat air conditioner

An air conditioning device for a vehicle includes a seat air conditioning unit that blows out air from a front side of a seat and an interior air conditioning unit that blows out air whose temperature has been adjusted by a cooling heat exchanger and a heating heat exchanger toward the vehicle interior space. The air conditioning device for a vehicle includes a first duct member for guiding the air flowing between the cooling heat exchanger and the heating heat exchanger in the interior air conditioning unit to the seat air conditioning unit. The air conditioning device for a vehicle further includes a second duct member for guiding the air higher in temperature than the air flowing between the cooling heat exchanger and the heating heat exchanger to the seat air conditioning unit.

Air conditioning device for vehicle

A seat air conditioner is applied to a seat disposed in a vehicle interior space and includes a seat back portion which supports an upper body side of a user and a seat cushion portion that supports a lower body side of the user. The seat air conditioner includes multiple air flow ducts provided in at least one of the seat back portion or the seat cushion portion and define an air flow passage for air to be blown out from the seat or air to be drawn into the seat. Some of the multiple air flow ducts are configured to be independent from the other air flow ducts such that air, which is different in temperature from the air flowing through the other air flow ducts, is allowed to flow through the some air flow ducts.

A seat air-conditioning device is provided with an air blowout portion which is open so as to blow out air toward a seated occupant seated on a vehicle seat, the air being blown from a ventilator. A control device of the seat air-conditioning device causes a blowing direction changing device to change a blowing direction of the air blown our from the air blowout portion based on passenger information including a build and a sitting position of a passenger which is the seated occupant. Accordingly, air can be blown in a direction according to the build or the sitting position of the seated occupant.

Vehicle seat air-conditioning device

An air-conditioning device for a vehicle seat has a seat, an air conditioning duct, a floor-side connection part, a seat-side connection part, and a connection duct. A position of the seat is adjusted in a front-rear direction. The air conditioning duct guides air, which is supplied from an interior air-conditioning unit, to a lower side of the seat. The floor-side connection part is provided in a vehicle-compartment floor on the lower side of the seat and connects to a downstream side of the air conditioning duct in an air flow direction. The seat-side connection part is provided in a seat bottom surface. The connection duct has one end portion connecting to the floor-side connection part and an other end portion connecting to the seat-side connection part. The seat-side connection part transfers across the floor-side connection part in the front-rear direction when a position of the seat is adjusted in the front-rear direction. The connection duct is deformable and stretchable. The floor-side connection part and the seat-side connection part are arranged at different positions in a left-right direction when viewed from a front side of a vehicle.

Air-conditioning device for vehicle seat

An air conditioner for a vehicle seat has: a centrifugal fan; a first case housing the fan and including a fan inlet and a fan outlet; and a second case providing an inlet-side air passage and an outlet-side air passage. The second case has; an inside-air inlet introducing air from a surface of the vehicle seat into the inlet-side air passage; a conditioned-air inlet introducing conditioned air from an air conditioning unit for a passenger compartment into the inlet-side air passage; a conditioned-air outlet through which air in the outlet-side air passage flows to the surface of the vehicle seat; and an exhaust-air outlet through which air in the outlet-side air passage flows out of the second case. The second case includes: an inlet-side switching door that selectively opens or closes the inside-air inlet and the conditioned-air inlet; and an outlet-side switching door that selectively opens or closes the conditioned-air outlet and the exhaust-air outlet.

Air conditioner for vehicle seat

A connection duct has (i) a duct body that is made of a material having great flexibility, the duct body in which the conditioned air flows and (ii) core members that are made of a material having higher rigidity than the duct body and are arranged, in the duct body, along a flow direction of air, the core members that maintain a cross-sectional shape of the duct body at a specified cross-sectional shape. The core members respectively have (i) an outer plate that is located on an outer peripheral side in the curved portion, (ii) an inner plate that is located on an inner peripheral side in the curved portion, and (iii) a connection plate that connects the outer plate with the inner plate. A length of the outer plate in the flow direction is longer than a length of the inner plate in the flow direction.

A seat air conditioning device that blows out air from a seat, supplied from an interior air conditioning unit that air-conditions a space in a passenger compartment for a vehicle, includes: a floor-side duct and a seat-side duct. The floor-side duct is disposed adjacent to a floor of a vehicle body member forming the space in the passenger compartment and is connected to the interior air conditioning unit. The air supplied from the interior air conditioning unit flows through the floor-side duct. The seat-side duct is disposed adjacent to the seat and communicates with the floor-side duct through a connecting duct. The connecting duct is configured to be deformed to follow displacement of the seat, and is arranged along a vehicle harness that connects a floor-side wiring member disposed adjacent to the floor and a seat-side wiring member disposed adjacent to the seat.
