ABSTRACT:
A user-operated seat uplift apparatus including a structural frame unit and a mechanical uplift assembly unit, thereby allowing the user to more easily obtain a standing position from a previous seated position. The structure frame unit is used to support and guide the mechanical uplift assembly unit. The uplift unit consists basically of a seat member, two rail members, one disposed on each side of the seat member, and an interconnection means. The user presses downward upon the rail members, which move in a downward direction. This downward movement produces an upward movement in the seat member. And likewise, downward movement of the seat member results in upward motion of the rail members. This interface allows the user to more easily uplift themselves from a seated position and should prove especially useful for older and medically disabled persons.
