Abstract
A medical chair includes a base, a seat, and a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position. The chair further includes a first actuator for tilting the seat with respect to the base, a second actuator for lifting the seat with respect to the base, and a leg rest actuator adapted to move the leg rest. The chair also includes a controller adapted to control the first and second actuators to move the seat between a first position and a second position such that the seat is both lifted and tilted at the same time as the seat moves from the first position to the second position, and wherein the controller is adapted to control the leg rest actuator such that the leg rest maintains a substantially constant orientation with respect to the floor.
