A vehicle ventilation system includes a seating assembly including a seat blower. The seat blower pulls air away from a seating surface. A cabin blower is configured to circulate air in a cabin. A controller is configured to monitor a flow rate of the cabin blower. The controller is also configured to control a seat blower flow rate as a function of a cabin blower flow rate.

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.

A seat conditioning module for a seat conditioning assembly including an air mover, an intake port, outtake port, wherein at least one of the intake port, the outtake port, or both are in fluid communication with a seat surface. A valve assembly with at least two apertures movably disposed between the air mover and the at least one intake and at least one outtake ports. An actuation device for moving the valve assembly to control the passage of the fluid through the at least two apertures. An optional conditioning device in fluid communication with the air mover and the seat surface. A control device for at least controlling the position of the at least two apertures of the valve assembly, the activation of the optional conditioning device, the operation of the air mover, or any combination thereof.

A vehicle air conditioning device includes: a sucking section provided at a seat that is disposed over a floor portion of a cabin, the sucking section configured to suck air via the seat from a vehicle front side relative to the seat, from a floor portion side relative to a vehicle vertical direction middle of the cabin; and a guiding section configured to guide air sucked by the sucking section toward the floor portion side at a vehicle rear side relative to the seat or toward a vehicle upper side.

A seating module for a seat, in particular a vehicle seat, may have at least a substantially air-permeable upholstery part. The upholstery part is substantially configured to let air-flow pass through horizontally.

A heating and cooling stimulation device includes a stimulation supply unit configured to supply hot stimulation and cold stimulation to a subject; an estimation unit configured to estimate a fatigue level of the subject; and a control unit configured to control an operation of the stimulation supply unit so as to supply the hot stimulation and the cold stimulation alternately to the subject in accordance with the fatigue level estimated by the estimation unit. The control unit controls the operation of the stimulation supply unit such that an amount of the cold stimulation received by the subject increases as the fatigue level estimated by the estimation unit becomes higher.

A ventilation seat of a vehicle is proposed. The ventilation seat includes a ventilation pipe mounted in a seat of the vehicle and configured to suck indoor air and to discharge air toward a surface of the seat, a catalytic converter provided in an air flow path of the ventilation pipe, and configured to clean air passing through the air flow path when light is emitted, and a light source assembly provided on an inner wall of the air flow path of the ventilation pipe and arranged to face the catalytic converter to emit the light toward the catalytic converter.

A seat air conditioner includes a blower and a seat back. The seat back includes: a cover, which is air-permeable, and a back pad having a plurality of ventilation holes through which an air flow generated by the blower passes. A ventilation passage is connected to the plurality of ventilation holes. When a part of the seat back exposed to a person is evenly divided into a first back portion, a second back portion, a third back portion, a fourth back portion, a fifth back portion and a sixth back portion in this order from a lower side, the back pad has a thoracic spine corresponding portion corresponding to the third back portion and the fourth back portion. An area occupied by the ventilation holes per unit area in the thoracic spine corresponding portion is larger than that in a portion other than the thoracic spine corresponding portion.

By promoting air circulation, heat and humidity are reduced more efficiently. A vehicle seat ventilation mechanism includes: a body case which is provided in a cushioning material of at least one of a seat cushion and a seat back and whose interior is an air circulation space; a fan disposed in the body case; and an exhaust port which is provided at a position apart from the fan and discharges an air stream created by air suction by the fan. The air stream enhances the comfort of a microclimate condition on a vehicle seat side which is a rear side of a contact surface, and with this microclimate condition, a thermal environment on a seat occupant side having an increased causal factor of discomfort is replaced, thereby making it possible to enhance the comfort of the clothing microclimate.

A vehicle ventilation system includes a seating assembly including a seat blower. The seat blower pulls air away from a seating surface. A cabin blower is configured to circulate air in a cabin. A controller is configured to monitor a flow rate of the cabin blower. The controller is also configured to control a seat blower flow rate as a function of a cabin blower flow rate.
