Abstract
A liftchair for a disabled person, or a person with weak legs. It has a seat adapted selectively to move vertically down from a normal sitting-height and to a position close to and directly above the floor, and again up to the normal sitting height. A drive mechanism to move the seat up and down includes a reversible electric motor and reversible control switch to selectively move the seat up or down in the liftchair. A brake is included to automatically lock the seat in any vertical position upon the motor being de-activated.
