Abstract: A seat includes an air discharge port configured to provide a thin stream of conditioned air along a body surface of a seat occupant. The air discharge port is part of an air supply component located in or along the seat bottom or backrest. The air discharge port is positioned to direct conditioned air along an external surface of the air supply component or of another surface of the seat to form an initial thin stream of conditioned air that follows external seat surfaces to reach and flow along the seat occupant. The air supply component can be made adjustable to allow the location and/or direction of the discharged air to be changed to accommodate and maintain the conditioned air in a thin stream.
