Abstract

A position controller for controlling a motorized, reclining chair comprising a track attached to a frame of the chair and a controller switch slidable in the track. The reclining chair includes a motor that controls movement of a backrest of the chair into a reclining position and extension of a footrest of the chair into an extended position. The controller switch is slidable in the track so that it remains within reach of the user throughout the range of motion of the reclining chair. The position controller also includes a pressure switch that activates the control switch in response to loading of the seating area of the recliner, so that the motorized chair can be operated only by a seated user. The control switch includes a toggle switch that the user can easily manipulate by hand to control movement of the chair.

Claims

1. A motorized chair having user-supporting surfaces that are movable relative to each other and are controllable by a user sitting on the chair, said chair comprising:

a frame supporting at least two user-supporting surfaces that are movable relative to each other for positioning the user across a range of motion;

a motor connected to said frame and to the user-supporting surfaces for moving the user-supporting surfaces; and

a position controller for controlling the motor, said position controller comprising a switch connected to the motor and movably supported on the frame so as to be traversable along the frame along a predetermined path by the user, said switch being operable in any position along said path, whereby the user can move the switch so as to remain within the reach of the user throughout the range of motion as the user-supporting surfaces of the chair are moved relative to each other.

2. A motorized chair of claim 1, further comprising a pressure switch connected to the position controller and operable in response to loading of one user-supporting surface to enable the position controller to control the motor.

3. A motorized chair of claim 2, wherein the pressure switch is also operable in response to unloading of one user-supporting surface to disable the position controller.

4. A motorized chair of claim 1, wherein the at least two user-supporting surfaces comprise a back supporting surface and a seating surface.

5. A motorized chair of claim 1, wherein the position controller further includes a track supported on the frame and wherein the switch is slidable in said track.

6. A motorized chair of claim 1, wherein the at least two user-supporting surfaces comprise a back supporting surface, a seat supporting surface and a footrest supporting surface.

7. A motorized chair of claim 1, wherein the switch is a toggle switch.

8. A motorized chair of claim 1, wherein the track is supported on the frame in a horizontal orientation.

9. A motorized chair of claim 1, wherein the track is supported on the frame in an orientation parallel to an armrest of the chair.

10. A motorized chair of claim 9, further comprising upholstery covering the frame and surrounding a periphery of the track.

11. A position controller for controlling a motorized chair, said motorized chair including a motor, at least two user-supporting surfaces and a frame, said user-supporting surfaces moveable relative to each other and said motorized chair controllable by a user sitting on the chair, said position controller comprising:

a track configured to be supported on the frame; and

a switch configured for connection to the motor and supported in said track at a position reachable by the user, said switch being slidable in said track so that the switch remains within the reach of the user throughout the range of motion as the user-supporting surfaces of the chair are moved relative to each other.

12. A position controller of claim 11, further comprising a pressure switch connected to the position controller and operable in response to loading of one user-supporting surface to enable the position controller to control the motor.

13. A motorized chair of claim 12, wherein the pressure switch is also operable in response to unloading of one user-supporting surface to disable the position controller.

14. A motorized chair of claim 11, wherein the switch is a toggle switch.
