Abstract: A vehicle seat for use with a ventilation system is provided. The seat includes an air-conducting layer, which may be provided underneath a seat surface. The air-conducting layer may cooperate with intake spots in a seat portion. The intake spots may be placed on lines substantially corresponding to the position of the legs of a person sitting in the seat and/or on a line extending substantially along the spine of a person sitting in the seat.

Abstract: A vehicle seat having a ventilation system includes a network of ducts within the seat bottom, and a fan for moving air away from the seat surface. The ventilation system is configured such that a single fan may selectively move air through some or all of the ducts. Before a vehicle occupant sits in a seat, air is moved through all of the ducts to reduce the temperature at the seat surface. When the occupant sits in the seat, certain ducts in the network are closed to air flow. The air flow is now limited to the remaining ducts, which allows for efficient removal of moisture from the seat surface. After the temperature and moisture at the seat surface have reached desired levels, the speed of the fan is reduced to ensure that the occupant does not experience an unpleasant draught.

Abstract: A rear ventilation system for a vehicle includes an air intake pump having a blower disposed within the housing to generate a forced flow of air into a thermal control. The thermal control includes a set of passages which direct air toward a heating and cooling core. The heating and cooling core includes a plurality of thermoelectric element units in communication with a direct current (DC) power supply disposed between a pair of heat exchangers. The plurality of thermoelectric element units absorb or generate heat employing the Peltier effect. The tempered air is delivered to at least one duct extending from the thermal control into the interior of the rear portion of the passenger compartment. A vent outlet in communication with the at least one duct extends into the rear passenger compartment to distribute air from the rear ventilation system.

Abstract: This invention relates to a vehicle seat having two seat parts, namely a seat bottom (1) and a backrest. At least one of the seat parts (1) comprises a ventilation system, consisting of a network of ducts (2, 3, 4, 5). A subset of these ducts (4) is at least partially closable with a view to permitting redirecting of air flows through the seat part.

Abstract: A board-mounted nozzle for ventilation and climate control installations which is intended primarily for motor vehicle compartments and which comprises a frame (1) supporting parallel interconnected guide vanes (2) which are hingedly mounted in the frame for pivotal movement to direct an air flow passing through the frame. Each guide vane (2) is formed with a recess (4) on at least one of its end faces the nozzle further comprises pivot pins (8) which are secured in the frame (1) in a resiliently flexible manner in order to exert a pushing force on these guide vanes (2).
