2077074 9112750 PCTABS00007 An adjustable chair in which the mutual angle between seat (1; 1') and backrest (2; 2') may be changed, with a stationary fixture (3; 3') provided at each of the sidepieces of the chair, with seat (1; 1') being mounted to be tiltable about a fixed point (4; 4') on the fixture and with backrest (2; 2') being mounted to be tiltable about a fixed rear point (5; 5') on fixture (3; 3'). Below said rear fixed point a spigot (12; 12') projects laterally from the lower portion of the backrest and is designed to slide in a slide groove (11; 11') which slopes rearwards, downwards in a side piece (25; 25') of seat (1; 1'). At least one mechanism (7, 8; 7', 8') of optionally adjustable length forms the connection between a mounting point (6, 6') of said fixture (3, 3') and a lower point (9, 9') of the backrest for activation of said mechanisme to cause movement of the spigot in said slide groove. When the backrest is moved backwards the rear edge of the seat will tilt downwards, and when the backrest is moved forwards the rear edge of the seat will tilt upwards.
