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.
