<p>The chair comprises a back (2) and a seat (3) which has two supporting surfaces (4,5) set at an obtuse angle to one another. The front surface (4) is basically horizontal, while the rear one slopes down from it towards the back, with which it forms an acute angle. The seat can be raised or lowered by a power cylinder (23), the two sections of the seat can be adjusted relative to one another, and the angle and position of the back can be adjusted by screw mechanisms (12,26,33). <IMAGE></p> |
