ABSTRACT:
A dental patient's chair which is fully and completely adjustable which includes a foot control system that eliminates the need to manipulate any hand-operated control knobs or levers. The dental patient's chair includes a linkage assembly which allows the seat to pivot and move in the same manner as the human body when the human body articulates about the complex pivot created at the pelvic bone, the upper legs, and the lower part of the backbone. The dental patient's chair allows the patient's body to remain in the same position relative to the backrest and the seat of the patient's chair as the chair is articulated in a variety of positions.
