Abstract
An air conditioned seat with a padded seat surface (4) and a padded backrest (8) and with a fan (16) arranged beneath the seat surface (4). The fan (16) is connected to an air distribution apparatus (20, 22) in the seat, and includes a flow region (31) that is open to the environment. The flow region (31) is located substantially on the side of the fan (16) facing the seat surface (4). The fan inlet (30) is further environmentally protected by a diffuser (36) located in the flow region (31) and forming a slit opening (40) between a top edge (38) of the diffuser (36) and an underside (28) of the seat.
Claims19
An air conditioned seat, comprising:
- a padded seat and a padded backrest, each having an occupant side and an underside;
- at least one first air distribution structure located on the underside of the padded seat or the padded backrest;
- at least one second air distribution structure located on the occupant side or adjacent to the occupant side of the padded seat or padded backrest, wherein the first and second air distribution structures are in fluid communication through one or more air ducts in the padded seat or padded backrest;
- a seat cover comprising a plurality of air outlets or comprising an air permeable fabric;
- at least one fan in fluid communication with the at least one first distribution structure through a bellows, wherein the fan is configured to push air through the first air distribution structure to the second air distribution structure via the one or more air ducts.
