Abstract

A treatment chair assembly comprising a treatment chair and a chair base, the chair assembly being pivotally or swingably connected to a chair base, in which a chair elevating mechanism is housed, so that the chair can be turned upward from and downward to the chair base. With this treatment chair assembly, it is not necessary to separate the treatment chair from the chair base and move the treatment chair to a different place when the chair elevating mechanism and the instrument drive/control unit are maintained, checked or repaired. The treatment chair can be turned upward by pivoting or swinging without separating and moving the treatment chair. As a result, labor can be saved and no space is required to temporarily store the treatment chair. The space for a dental treatment room can be used effectively. Furthermore, since the chair is not separated or moved, less concern for staining or breaking the chair due to bumping against objects is necessary.
