PCT No. PCT/SE86/00255 Sec. 371 Date Feb. 3, 1987 Sec. 102(e) Date Feb. 3, 1987 PCT Filed Jun. 2, 1986 PCT Pub. No. WO86/07243 PCT Pub. Date Dec. 18, 1986.Arrangement for an operator's seat with a foot control for a working machine which can be operated by an operator, the operation of which occurs through the adjustment of the foot control (30) to different angular positions. The foot control acts as a support for at least one of the operator's feet during work and is connected to the seat unit (5) of the operator's seat in such a way that the foot control is connected to the seat unit and is so arranged as to accompany it as it moves. The movements of the seat unit and the accompanying foot control are determined by a guide arrangement connected to the operator's seat, which guide arrangement permits the movement of the operator's seat towards and away from the working machine between different positions for varying the distance between the operator and the working machine without affecting the position of the foot control relative to the seat unit through the aforementioned movements. The foot control is adjustable in relation to the seat unit, in this way giving the operator an ergonomically correct working position irrespective of his physical size. The seat unit (5) is supported by a telescopically extending upright (9) which can be displaced along the guide. The foot control is supported by a foot support unit (1) which can be moved between different heights along the upright (9). Arranged between the foot control and the upright is an essentially horizontal supporting plane (29) for the operator's feet. The upright is inclined rearwards in a direction away from the working machine and constitutes a sloping path for the foot support unit, such that a change in position in the vertical sense will also produce a pre-determined change in position in the horizontal sense.
