ABSTRACT:
An operational chair for dental work is automatically actuated, preferably with hydraulic adjusting devices, in relation to the seat height, inclination of the back of the chair and the swinging of the chair about a transverse axis and possibly also about a longitudinal axis. Adjusting members are used for holding initial positions and bringing about the desired positions for each of the adjusting devices. The invention is particularly characterized by the provision of a group of members providing the required values for each position which can be selected. These members can be connected by a position selector, for example, a selecting key, with actuating means for the adjusting devices, the actuating means being firmly coupled with members holding the initial positions.
