摘要:
A dental patient chair comprises an arrangement for adjusting the seat height, the inclination position of the seat and the backrest, as well as the position of the seat and backrest with reference to a longitudinal direction of the chair. The arrangement includes two pivotably connected arms having one arm pivotably connected to a pedestal and the other connected to the seat and being provided with a drive arrangement for shifting the arms relative to their pivotable connection to move the seat in both a vertical and horizontal direction, as well as to tilt the seat relative to a base plane. The arrangement includes a control device for operating the drive arrangement for pivoting the arms relative to the pivotable connections between themselves and to the pedestal and seat.
