摘要：
A medical chair includes a seat supported by a base and actuators adapted to both tilt and lift the seat with respect to the base. A controller controls the actuators to both lift and tilt the seat as the seat moves from the sitting position to the standing position. The movement from the sitting position to the standing position assists in the egress of an occupant from the chair, while the movement from the standing position to the sitting position assists in the ingress of an occupant to the chair. A backrest on the chair remains substantially vertically oriented during movement between the sitting and standing position so as to provide more comfort to the occupant during the sit-to-stand or stand-to-sit movement. The backrest also moves in a manner that generally keeps the occupant's torso vertically aligned with his or her hips during this movement.
