Abstract

A chair component includes a first chair member adapted to support a seated user, a second chair member movable between a first position, wherein the second chair member is substantially coplanar with the first chair member, and a second position, wherein the second chair member is substantially parallel with the first chair member, a cover member wrapped about at least a portion of the first chair member and at least a portion of the second chair member, and a single-piece drawstring operably coupled with the cover member to draw the cover member about the at least a portion of the first chair member and the at least a portion of the second chair member when the second chair member is in the first position.

Claims

1. A chair component, comprising:

a first chair member adapted to support a seated user;

a second chair member movable between a first position, wherein the second chair member is substantially coplanar with the first chair member, and a second position, wherein the second chair member is substantially parallel with the first chair member;

a cover member wrapped about at least a portion of the first chair member and at least a portion of the second chair member; and

a single-piece drawstring operably coupled with the cover member to draw the cover member about the at least a portion of the first chair member and the at least a portion of the second chair member when the second chair member is in the first position.

2. The chair component of claim 1, wherein the drawstring abuts the first chair member.

3. The chair component of claim 1, wherein the drawstring is secured to the first chair member by at least one fastener that is separate from the first chair member.

4. The chair component of claim 3, wherein the at least one fastener comprises at least one staple.

5. The chair component of claim 1, wherein the first chair member includes at least one first coupler and the second chair member includes at least one second coupler that engages the first coupler, thereby securing the second chair member to the first chair member when the second chair member is in the second position.

6. The chair component claim 5, wherein the at least one first coupler and the at least one second coupler comprise a quick-connect fastener.

7. The chair component of claim 1, wherein the cover member includes a fabric portion and a drawstring tunnel located proximate an edge of the fabric portion, wherein the drawstring is received within the drawstring tunnel.

8. The chair component of claim 7, wherein the drawstring tunnel and the drawstring are secured to a rear surface of the first chair member by at least one fastener.

9. The chair component of claim 7, wherein the fabric is elastically deformable in at least one direction.

10. The chair component of claim 1, wherein the chair component comprises a chair back assembly.

11. The chair component of claim 10, wherein the second chair member comprises a back seat shell.

12. A seating arrangement comprising the chair component of claim 1.

13. The seating arrangement of claim 12, wherein the seating arrangement comprises an office chair assembly.

14. A chair component, comprising:

a first chair member adapted to support a seated user;

a second chair member movable between a first position, wherein the second chair member is substantially coplanar with the first chair member and the second chair member is spaced from the first chair member, and a second position, wherein the second chair member contacts the first chair member;

a cover member wrapped about at least a portion of the first chair member and at least a portion of the second chair member; and

a single-piece drawstring operably coupled with the cover member to draw the cover member about the at least a portion of the first chair member and the at least a portion of the second chair member when the second chair member is in the first position.

15. The chair component of claim 14, wherein the drawstring abuts the first chair member.

16. The chair component of claim 14, wherein the chair component comprises a chair back assembly.

17. The chair component of claim 16, wherein the second chair member comprises a back seat shell.

18. A seating arrangement comprising the chair component of claim 14.

19. The seating arrangement of claim 18, wherein the seating arrangement comprises an office chair assembly.

20. A chair component, comprising:

a first chair member adapted to support a seated user, and that includes a front surface and a rear surface that define a first thickness therebetween, the first chair member further includes at least one raised portion extending rearwardly from the rear surface, wherein the front surface and the at least one raised portion define a second thickness therebetween that is greater than the first thickness, and wherein a majority of the first chair member comprises the first thickness;

a cover member wrapped about at least a portion of the first chair member; and

a drawstring operably coupled with the cover member to draw the cover member about the at least a portion of the first chair member, wherein the drawstring is secured to the first chair member by at least one fastener that is received within the at least one raised portion.
