Abstract

This is directed to a smart ergonomic chair and mobility system. The system can be used as a working station, a working chair, a mobility device, a personal care device, or a combination thereof. The system is designed to provide ergonomic seating posture for a person who is seated on the chair. The system is also designed to reduce body stress by providing automatic movements of parts of the chair at predefined time points.

Claims

1. A chair system comprising:

a seating module configured to support a person, said seating module comprises a polarity of movable parts;

a seat support module coupled to the seating module;

a mobility module functionally coupled to the seating module configured to independently cause defined movements of each of the movable parts based on control signals; and

a control module functionally coupled to the mobility module to provide the control signals;

wherein the control module is configured to provide the control signals to the mobility module to cause defined movements of one or more of the movable parts at a set of predefined time points when the chair system is in operation;

wherein the seating module comprises a seat back, a head rest, a seat bottom, a foot rest and a pair of arm rests functionally coupled together forming a chair, wherein the movable parts are selected from the seat back, a part of the seat back, the head rest, a part of the head rest, the seat bottom, a part of the seat bottom, the foot rest, a part of the foot rest, the arm rests, a part of the arm rests, the seat support module, a part of the seat support module, or a combination thereof; and

wherein said foot rest has one side affixed to a foot rest coupling that is affixed to the seat support module or the seat bottom, wherein the foot rest coupling has a rotational axis F-F′

that is parallel to perspective surface planes of the foot rest and the seat bottom so that the foot rest is configured to rotate along said rotational axis F-F′

.

2. The chair system of claim 1, wherein the control module is selected from a wired control device, a wireless control device, or a combination thereof.

3. The chair system of claim 2, wherein the wireless control device comprises a motion sensor, and wherein the wireless control device is configured to provide one or more of the control signals by predefined motions of the wireless device.

4. The chair system of claim 1 further comprising a working module coupled to the seating module, the seat support module, or a combination thereof, wherein the working module comprises an accessory frame and a working accessory functionally coupled together.

5. The chair system of claim 4, wherein the control module is further configured to provide a warning signal based on a predefined schedule and wherein the working module further comprises a warning device functionally coupled to the control module to provide a predefined warning based on a warning signal.

6. The chair system of claim 4, to wherein the working accessory comprises a working surface, a device holder, and an optional illumination device.

7. The chair system of claim 1, wherein the mobility module further comprises an energy storage device.

8. The chair system of claim 7 further comprising a solar energy device functionally coupled to the energy storage device.

9. The chair system of claim 1 further comprising a discharge processing module functionally coupled to the seating module, the seat support module, or a combination thereof, to receive and store discharged materials.

10. The chair system of claim 1 further comprising a plurality of sensors functionally coupled to the seating module, the supporting module and the control module.

11. The chair system of claim 1 further comprising at least a treatment device for treating a body condition of a person, wherein the treatment device is selected from an electronic treatment device, a light treatment device, an electron-magnetic treatment device, a thermal treatment device, a mechanical treatment device, or a combination thereof.
