Abstract

A seating arrangement includes a seat assembly, a control assembly, a back assembly, and a quick-connection arrangement to connect the back assembly to the control assembly, where the back assembly includes first and second reliefs and the control assembly includes first and second shafts received within the first and second reliefs respectively, and a locking arrangement that includes a primary locking member pivotable between a locked position, where the primary locking member abuts the second shaft arrangement, thereby preventing the second shaft arrangement from being removed from within the second relief, and an unlocked position, where the second shaft arrangement may be removed from within the second relief, thereby allowing the back assembly to be uncoupled from the control assembly.

First claim

The invention claimed is:

1. A seating arrangement, comprising:
a seat assembly configured to support a seated user thereon;
a control assembly supporting the seat assembly;
a back assembly adapted to couple to the control assembly and extending upwardly from the seat assembly; and
a quick-connection arrangement to connect the back assembly to the control assembly, comprising:
a first relief and a first shaft arrangement, wherein one of the back assembly and the control assembly includes the first relief, and the other of the back assembly and the control assembly includes the first shaft arrangement received within the first relief;
a second relief and a second shaft arrangement, wherein one of the back assembly and the control assembly includes the second relief, and the other of the back assembly and the control assembly includes the second shaft arrangement received within the second relief; and
a locking arrangement that includes a primary locking member pivotable between a locked position, wherein the primary locking member abuts the second shaft arrangement, thereby preventing the second shaft arrangement from being removed from within the second relief, and an unlocked position, wherein the second shaft arrangement may be removed from within the second relief, thereby allowing the back assembly to be uncoupled from the control assembly.

2. The seating arrangement of claim 1 , wherein the primary locking member pivots about a pivot point that is offset from a longitudinal axis of the first shaft arrangement and a longitudinal axis of the second shaft arrangement.

3. The seating arrangement of claim 1 , wherein the primary locking member is biased from the unlocked position toward the locked position by a biasing member.

4. The seating arrangement of claim 3 , wherein the biasing member comprises a leaf spring.

5. The seating arrangement of claim 1 , wherein the first relief comprises a laterally extending channel.

6. The seating arrangement of claim 5 , wherein the second relief comprises a laterally extending channel.

7. The seating arrangement of claim 1 , wherein the control assembly includes the first shaft arrangement and the back assembly includes the first relief.

8. The seating arrangement of claim 7 , wherein the control assembly includes the second shaft arrangement and the back assembly includes the second relief.

9. The seating arrangement of claim 1 , wherein the seating arrangement comprises an office chair assembly.

10. A method for assembling a seating arrangement, comprising:
providing a seat assembly configured to support a seated user thereon;
providing a control assembly supporting the seat assembly;
providing a back assembly adapted to couple to the control assembly and extending upwardly from the seat assembly; and
connecting the back assembly via a quick-connect arrangement, comprising:
providing a first relief and a first shaft arrangement, wherein one of the back assembly and the control assembly includes the first relief, and the other of the back assembly and the control assembly includes the first shaft arrangement configured to be received within the first relief;
providing a second relief and a second shaft arrangement, wherein one of the back assembly and the control assembly includes the second relief, and the other of the back assembly and the control assembly includes the second shaft arrangement configured to be received within the second relief;
providing a locking arrangement that includes a primary locking member pivotable between a locked position where the primary locking member abuts the second shaft arrangement, thereby preventing the second shaft arrangement from being removed from within the second relief, and an unlocked position, wherein the second shaft arrangement may be removed from within the second relief, thereby allowing the back assembly to be uncoupled from the control assembly;
positioning the first shaft arrangement within the first relief;
rotating the back assembly with respect to the control assembly until the second shaft arrangement is positioned within the second relief; and
pivoting the primary locking member from the unlocked position to the locked position, thereby preventing the second shaft arrangement from being removed from within the second relief.

11. The method of claim 10 , wherein pivoting the primary locking member includes pivoting the primary locking member about a pivot point that is offset from a longitudinal axis of the first shaft arrangement and a longitudinal axis of the second shaft arrangement.

12. The method of either of claim 10 , wherein the primary locking member is biased from the unlocked position toward the locked position by a biasing member.

13. The method of claim 10 , wherein the first relief comprises a laterally extending channel.

14. The method of claim 10 , wherein the control assembly includes the first shaft arrangement and the back assembly includes the first relief.

15. The method of claim 10 , wherein the seating arrangement comprises an office chair assembly.

16. A seating arrangement, comprising:
a seat assembly configured to support a seated user thereon;
a control assembly supporting the seat assembly;
a back assembly coupled to the control assembly and extending upwardly from the seat assembly; and
a quick-connection arrangement, comprising:
a relief and a shaft arrangement, wherein one of the back assembly and the control assembly includes the relief, and the other of the back assembly and the control assembly includes the shaft arrangement received within the relief; and
a locking arrangement that includes a primary locking member movable between a locked position wherein the primary locking member abuts the shaft arrangement, thereby preventing the shaft arrangement from being removed from within the relief, and an unlocked position wherein the shaft arrangement may be removed from within the relief, thereby allowing the back assembly to be uncoupled from the control assembly, and a secondary locking member operably coupled to the primary lock member and configured to prevent the primary locking member from moving from the locked position to the unlocked position.

17. The seating arrangement of claim 16 , wherein the secondary locking member is pivotably coupled to the primary locking member.

18. The seating arrangement of claim 16 , wherein the secondary locking member is movable between a first position, wherein the secondary locking member prevents the primary locking member from moving from the locked position to the unlocked position, and a second position, wherein the primary locking member is movable from the locked position to the unlocked position thereby allowing the shaft arrangement to be removed from within the relief.

19. The seating arrangement of claim 18 , wherein the secondary locking member is biased from the second position toward the first position thereof.

20. The seating arrangement of claim 16 , wherein the secondary locking arrangement is configured to abut the shaft arrangement as the shaft arrangement is moved from a position outside of the relief to a position within the relief.

21. The seating arrangement of claim 16 , wherein the primary locking member is pivotable between the locked position and the unlocked position thereof.

22. The seating arrangement of claim 16 , wherein the seating arrangement comprises an office chair assembly.
