Each draught excluder has a frame (30) which pivots on one of two seat uprights (212a,121b) when activated by a screw. The two screws are located transverse to the seat (1) and connected in rotation by a transmission mechanism (23). This mechanism (23) is formed by two pulleys fixed by screws and by a cable on the pulleys. The cable has two sections whose directions of displacement are opposite. It extends parallel to the length of the two uprights (121a,121b) and to the cross member (122) of the back (12). ADVANTAGE - Adjusts draught excluders separately from the lumbar support.
