Abstract
A chair is electrically and mechanically adjustable through a wide range of positions in a cost-effective and reliable manner. The chair includes a seat and a back coupled to a control mechanism and supported on a base. A height adjustment mechanism is coupled to a motor and extends between the base and the seat for controlling a height of the seat with respect to the base. A limit switch controls an amount of movement of the seat with respect to the base. The control mechanism is pivotally coupled between the chair seat and the height adjustment mechanism and mechanically and electrically adjusts a position of the seat with respect to the base. More specifically, the control mechanism permits mechanical adjustments of a position of the seat to be made that are independent of electrical adjustments of the seat.
