Abstract
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.
