A stroller seat is mounted on a stroller and is provided with: a main part extending from a backrest to a seating part of the stroller and having a space therein through which air flows; an extension part protruding from at least one of the two side portions of the main body and having a space therein which communicates with the space of the main body; and a fan attachment part which is provided on the extension part and to which an electric fan can be attached. The main body has, on a surface to be in contact with a human body, an air discharge unit for discharging air therein to the outside. Air introduced by the electric fan attached to the fan attachment part flows into the main body through the extension part.

A vehicle seat for a motor vehicle, with a seat frame that can be attached to a vehicle floor, with a seat part supported by the seat frame, and with a ventilating device that has at least one controllable air-conveying device and at least one air outlet device flow-connected to the air-conveying device. Provision is made that a seat part element that lengthens the seat part is mounted on the seat frame so as to be longitudinally movable relative to the seat part, and that the seat part element has the ventilating device.

A seat component for a vehicle seat having at least one air outlet unit configured to be connected to an air supply. In order to be able to adapt a ventilation function of the vehicle seat individually to a contact area between the vehicle seat and a person sitting thereon, the air outlet unit has at least one flexible air guide funnel and at least one diaphragm valve which is arranged within the at least one flexible air guide funnel and which is connected to the at least one flexible air guide funnel in such a way that the diaphragm valve closes the air guide funnel when the air guide funnel is not deformed, and at least partially opens the air guide funnel when the air guide funnel is deformed.

A distribution system for a vehicle seat The distribution system includes one or more plenums that each have a cap layer, a support layer, and an open space formed between the cap layer and the support layer. The support layer is a generally rigid material and the cap layer is a generally flexible material that is connected to the support layer. The open space includes one or more baffles that assist in directing fluid between a blower connected to the one or more plenums and one or more ventilation holes.

A backrest of a vehicle seat comprises a backrest frame, a support plate fixed to the backrest frame, and at least one vibrating device. Each vibrating device is fixed to the support plate by means of at least one damping element. Preferably, each vibrating device is fixed on a face of the support plate opposite to the face intended to be oriented towards an occupant of the seat, at least a portion of each vibrating device being received in a respective through-hole in the support plate.

Proposed are a blower for a ventilation seat having a warm-air-blowing function and a vehicular ventilation seat including the same. The blower moves air supplied to the vehicular ventilation seat. The blower includes a housing having an accommodation space formed therein and including an inlet receiving air and an outlet discharging air, a motor mounted in the housing, an impeller mounted in the housing and configured to be driven by the motor to move air, a printed circuit board mounted in the housing, and a heater mounted in the housing so as to be connected to the printed circuit board and configured to heat the air flowing through the housing.

A ventilation module can be used with a ventilation seat for a vehicle. A thermoelectric air-conditioning part has a thermoelectric unit performing heat absorption and heat generation by using a Peltier effect when electric power is applied, a cooling unit provided at a first side of the thermoelectric unit, and a heat dissipation unit provided at a second side of the thermoelectric unit. The module is configured so that air that is supplied from a blower is cooled by the thermoelectric air-conditioning part, passes through a cooling fin of the cooling unit, and is discharged to an interior of the vehicle through a seat cushion. The module is configured so that air that is supplied from the blower is heated by the thermoelectric air-conditioning part, passes through a heat dissipating fin of the heat dissipation unit, and is discharged through the heat dissipation path.

A seat ventilation blower may include a first housing; a second housing coupled and assembled to the first housing; an impeller inserted inside the first housing or the second housing, the impeller configured to rotate; and a circuit board body having a motor assembly coupled to the impeller to rotate the impeller wherein the circuit board body is configured to control operation of the motor assembly and installed in the housing when the first and second housings are coupled and assembled together.

An example seat climate system includes a seat, a first ventilation device, a second ventilation device, and a ventilation device controller. The seat has a first ventilation layer and a second ventilation layer. The first ventilation device is connected to the first ventilation layer and has an off state and an on state. The first ventilation device moves air through the first ventilation layer when in the on state. The second ventilation device is connected to the second ventilation layer and has an off state and an on state. The second ventilation device moves air through the second ventilation layer when in the on state. The ventilation device controller is connected to the first ventilation device and the second ventilation device and includes a controller and driver.

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.
