Medical support apparatus
First Claim
1. A medical chair comprising:
- a base configured to resting on a floor;
a seat;
a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position;
a first actuator for tilting the seat with respect to the base;
a second actuator for lifting the seat with respect to the base;
a leg rest actuator adapted to move the leg rest; and
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.

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.

11. A medical chair comprising:
-
a base; a seat; a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position; a first actuator for tilting the seat with respect to the base; a second actuator for lifting the seat with respect to the base; a leg rest actuator adapted to move the leg rest; and 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 an angle defined between the seat and the leg rest changes during movement of the seat from the first position to the second position. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A medical chair comprising:
-
a base; a seat; a backrest pivotally mounted relative to the seat, the backrest forming a backrest angle relative to the seat; a leg rest pivotally mounted relative to the seat and adapted to move between an extended position and a retracted position; a backrest actuator for tilting the backrest with respect to the seat; a leg rest actuator adapted to move the leg rest; and a controller adapted to control the backrest actuator to adjust the backrest angle, and wherein the controller is adapted to control the leg rest actuator and delay actuation of said leg rest actuator when the backrest is being lowered until the backrest is lowered to a preselected angle. - View Dependent Claims (19, 20, 21)
