Abstract: The object of the invention is a junction device between a conduit mounted on a floor for supplying air, in particular coming from a heating, ventilation and/or air conditioning installation, and an aeration conduit mounted on the squab of a seat, mounted so as to move in rotation about an axis A1 fixed to the floor. The junction device comprises rigid members respectively allocated to the supply conduit and to the aeration conduit. These rigid members are mounted so as to move with respect to each other for putting the conduits in air communication with each other, at least in the folded-down position of use of the seat.
