The wheelchair comprises a mobile seat part (100) with respect to a lower part (200) of the chair, by means of a coupling mechanism comprising at least two arms (1, 1') which, to elevate the chair, rotate in opposite directions. Each arm can pivot with respect to the lower part (200) and the angular positions of the arms (1, 1') with respect to their coupling points (1A, 1A') for coupling to the lower part (200) determine both the height position and the tilting of the seat part (100) with respect to the lower part (200).
