<p>The chair has a hydraulic, pneumatic or electrical drive fed from a remote power source. The chair foot (2), connected to the chair frame, has the form of a box, the top side of which comprises a flat plate (7), while its periphery is pref. circular, rectangular or square in shape. In the floor (8,9) at the place where the chair is located is a well (6) dimensioned to accommodate the box, and with sufficient depth that the top plate upper side is located in the plane of the well surface. The box, at a level below the top plate, is provided with connections for the requisite power supply lines (20,21). - The supply lines are arranged below the floor plane, at least in an area around the floor well, and the plate located in the floor surface plane and the floor surface around the well are tightly connected to each other. A manoeuvring component (15) for the regulator (14) in the box extends through the plate, and is accessible from the plate top side for foot operation.</p> |
