ABSTRACT:
The present invention provides for a power operated chair that can be operated in a rock and swivel, recline, or lift mode or any combination thereof. The chair is specifically designed to prevent the rocking and swiveling motion when the occupant is using the lift or recline features of the chair. The chair uses a recline mechanical linkage and a seat lift mechanical linkage that are mechanically linked by a guide roller in a guide channel which permits the use of a single drive motor and provides for a smooth transition from the recline mode to the lift mode. The guide roller and guide channel also prevent the inadvertent lifting of the seat if the back of the chair is forcibly reclined.
