Separate support means (5,7 ; 5,6) are provided for the cushion (4) and the back (2) so that separate adjusting movements can be imparted to the cushion (4) and the back (2) along respective translation paths. The support means for the cushion (4) and the back (2) are connected together kinematically (5) in such a way that the movement of one of the cushion (4) and the back (2) involves the movement of the other of the cushion (4) and the back (2), and the extent of movement of the cushion (4) is a fraction of the extent (2) of movement of the back. |
