Abstract

A mobile task chair with a control mechanism with adjustment mechanisms and setting indicators. The mobile task chair has a mobile base structure, a control mechanism supported by the base structure, a seat bottom structure supported by the base structure, a seat back structure supported by the base structure, a mechanism for adjusting a physical setting of the mobile task chair, such as the pivoting resistance of the back structure, and a mechanism for providing a visual indication of the pivoting resistance of the mobile task chair.

Claims

1. A mobile task chair with a control mechanism with adjustment mechanisms and setting indicators, the mobile task chair comprising:

a mobile base structure;

a control mechanism supported by the base structure;

a seat bottom structure supported by the base structure;

a seat back structure supported by the base structure;

means for adjusting a physical setting of the mobile task chair; and

means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair.

2. The mobile task chair of claim 1 wherein the seat back structure is retained to pivot relative to the mobile base structure with a pivoting resistance, wherein the means for adjusting a physical setting of the mobile task chair comprises a means for adjusting the pivoting resistance of the seat back structure, and wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair comprises a means for indicating the pivoting resistance of the seat back structure.

3. The mobile task chair of claim 2 wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair comprises a means for providing an illuminated visual indication.

4. The mobile task chair of claim 2 wherein the means for adjusting the pivoting resistance of the seat back structure comprises a means for providing a gross pivoting resistance adjustment between multiple resistance zones.

5. The mobile task chair of claim 4 wherein the means for adjusting the pivoting resistance of the seat back structure further comprises a means for providing a fine pivoting resistance adjustment within the multiple resistance zones.

6. The mobile task chair of claim 4 further comprising a means for sensing the resistance zone and wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair has a visual indicator for each resistance zone.

7. The mobile task chair of claim 1 wherein there are means for separately adjusting multiple physical settings of the mobile task chair and wherein the means for providing a visual indication of the means for adjusting the setting of the mobile task chair provides a separate visual indication of each of the means for adjusting the multiple physical settings.

8. The mobile task chair of claim 7 wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair comprises a means for selectively inducing visual indications of the means for adjusting the multiple physical settings.

9. The mobile task chair of claim 8 wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair provides visual indications for a given time period after being selectively induced.

10. The mobile task chair of claim 7 wherein the seat back structure is retained to pivot relative to the mobile base structure with a pivoting resistance, wherein the means for adjusting a physical setting of the mobile task chair comprises a means for adjusting the pivoting resistance of the seat back structure, further comprising a means for sensing the pivoting resistance of the seat back structure, and wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair comprises a means for indicating the pivoting resistance of the seat back structure.

11. The mobile task chair of claim 10 wherein the means for adjusting the pivoting resistance of the seat back structure comprises a means for providing a gross pivoting resistance adjustment between multiple resistance zones and wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair has a visual indicator for each resistance zone.

12. The mobile task chair of claim 1 wherein the seat bottom structure is retained to adjust longitudinally in seat depth relative to the mobile base structure, wherein the means for adjusting a physical setting of the mobile task chair comprises a means for adjusting the seat depth of the seat bottom structure, further comprising a means for sensing the seat depth of the seat bottom structure, and wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair comprises a means for indicating the seat depth of the seat bottom structure.

13. The mobile task chair of claim 12 wherein the means for adjusting the seat depth of the seat bottom structure comprises a means for selectively adjusting between multiple seat depth positions and wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair has a visual indicator for each seat depth position.

14. The mobile task chair of claim 13 wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair has a visual indicator for each seat depth position.

15. The mobile task chair of claim 14 wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair has a light source for indicating each seat depth position.

16. The mobile task chair of claim 12 wherein the means for sensing the seat depth of the seat bottom structure comprises a plurality of sensors retained in series on one of the seat bottom structure and the mobile base structure and a contact retained by the other of the seat bottom structure and the mobile base structure.

17. The mobile task chair of claim 1 further comprising a means for providing a recommended setting of the physical setting of the mobile task chair.

18. The mobile task chair of claim 17 further comprising a means for inducing the physical setting to the recommended setting of the mobile task chair.

19. The mobile task chair of claim 18 wherein the means for inducing the physical setting to the recommended setting automatically adjusts the physical setting to the recommended setting.

20. The mobile task chair of claim 1 wherein the means for providing a visual indication of the means for adjusting the physical setting of the mobile task chair comprises a software application.
