The present invention relates to an air conditioner with at least one air conduction device and a switching device. Provision is made that in a first operating state, the air conditioner has air passing at least partially through it in a first direction, that the air conditioner has air flowing through it at least partially in a second direction different from the first direction, and that the air conditioner has at least one switching device, to alter the flow direction of the air in the air conduction device.

A climate controlled seat assembly includes a thermoelectric device having a main side and a waste side for generating a conditioned fluid stream and a waste fluid stream respectively, a fluid distribution system for distributing the conditioned fluid stream towards an occupant seated on the climate controlled seat assembly and for gathering and pulling fluid from around the occupant and directed this gathered fluid away from the occupant.

A car seat includes an air outlet located in a seat upper portion (a portion provided above a seat cushion and including a seat back and a headrest) to let out air therethrough; an air inlet located in the seat upper portion to draw in air therethrough; at least one fan configured to produce a current of air flowing from the air outlet toward the air inlet at a front side of the seat upper portion; and a scenting device configured to scent air to be forced out through the air outlet. The air outlet and the air inlet are located in such positions that at least part of the headrest is positioned between the air outlet and the air inlet in a direction from the air outlet toward the air inlet as viewed from a front side.

An air conditioning device for a vehicle seat, the air conditioning device includes: at least one flow generator to generate an air flow; at least one air inlet opening fluidically connected to a flow inlet of the flow generator to draw in air to be temperature-controlled; at least one air outlet opening fluidically connected to a flow outlet of the flow generator to eject the temperature-controlled air; and a temperature-control device configured to control a temperature of the air drawn in through the at least one air inlet opening prior to the air being ejected from the at least one air outlet opening; the at least one air inlet opening and the at least one air outlet opening are arranged next to one another.

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 car seat includes an air outlet located in a seat upper portion (a portion provided above a seat cushion and including a seat back and a headrest) to let out air therethrough; an air inlet located in the seat upper portion to draw in air therethrough; at least one fan configured to produce a current of air flowing from the air outlet toward the air inlet at a front side of the seat upper portion; and a scenting device configured to scent air to be forced out through the air outlet. The air outlet and the air inlet are located in such positions that at least part of the headrest is positioned between the air outlet and the air inlet in a direction from the air outlet toward the air inlet as viewed from a front side.

A centrifugal blower device includes a rotating shaft, a turbo fan unit and a casing. A shroud ring of the turbo fan unit and a cover portion of the casing form a gap between them. The gap includes a radial gap formed between the cover portion and the shroud ring in a radial direction and an axial gap formed between the cover portion and the shroud ring in an axial direction. The radial gap is located at a position outside of a shroud-side inner peripheral end in the radial direction. The axial gap is located at a position inside of the radial direction in the radial direction. A minimum gap dimension of the radial gap is smaller than a minimum gap dimension of the axial gap. A shortest distance between the shroud-side inner peripheral end and the cover portion is larger than the minimum gap dimension of the radial gap.

In order to make it possible to deal with the states of a seatback from an upright state to a fully reclined state without degrading performance of blowing air from a fan, attached to a seat cushion-side, toward the seatback-side, this vehicle seat having an air conditioning function, is configured to be provided with: an air conditioning fan; fan side piping which is connected with the fan; and seat cushion or seatback side piping which is connected with an air flow passage formed in the seat cushion or the seatback, wherein the fan side piping and the seat cushion or seatback side piping are coupled together slidably in a state where an end of one is partially inserted into an end of the other, and at least one piping of either the fan side pining or the seat cushion or seatback side piping is equipped with a bellows structure.

A seat air-conditioning device includes: a blower; a first ventilation path through which air is drawn in by the blower from a first inlet in a seat base of a seat on which a person sits; a second ventilation path through which the drawn air is discharged from a first outlet in the seat; a third ventilation path that is different from the second ventilation path and through which the drawn air is discharged from a second outlet in the seat; and an outlet ventilation path selection switch that is between the blower and the first and second outlets and selects at least one of the second and third ventilation path to which the drawn air is to be led. The first inlet is vertically below the first outlet and the second outlet.

A seat comprises: a seat cushion including a first mesh; a seat extension configured to move into a closed position and an extended position relative to the seat cushion, the seat extension including a second mesh; a first conduit forming a first air channel between the first and second meshes in the closed and extended positions; and a fan configured to draw air from the first and second meshes using the first conduit.
