摘要： A mounting assembly for a chair that enables a plurality of mechanical adjustments to be made to the chair by a seated occupant in a cost effective and reliable manner is described. The mounting assembly is coupled to a control mechanism which includes a plurality of motor-gear groups and at least one control switch. The control switch is coupled to each motor-gear group, a rechargeable battery, and to a limit switch that limits an amount of electrical height adjustment of the chair seat with respect to the chair base. Each motor-gear group is coupled to a drive shaft and are used to electrically adjust the chair. As a result, a seated occupant may selectively engage mechanically adjust the chair seat relative independently of electrical adjustments available by the control mechanism.

摘要： 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.
