Abstract

A chair component assembly includes a support component adapted to support a portion of a seated user and including a shell member having an outer peripheral edge, the support component further including at least one coupler having an interior and an opening facing the outer peripheral edge of the shell member, and at least one tab member located substantially proximate the opening of the at least one coupler, and an upholstery cover assembly wrapped about at least a portion of the support component and including an edge that is retained within the interior of the at least one cupler by the at least one tab member.

Claims

1. A chair component assembly, comprising:

a support component including a surface adapted to support a portion of a seated user and facing in a first direction, the support component comprising;

a shell member having an outer peripheral edge;

at least one coupler having an interior and an opening facing the outer peripheral edge of the shell member and that is transverse to the surface of the support component; and

at least one tab member located substantially proximate the opening of the at least one coupler, wherein the at least one tab member extends away from the surface of the support component and into the interior of the at least one coupler; and

an upholstery cover assembly wrapped about at least a portion of the support component and including an edge that extends through the opening of the least one coupler is retained within the interior of the at least one coupler by the at least one tab member.

2. The chair component assembly of claim 1, wherein the upholstery cover assembly includes a flexible cover portion and a stile member that is substantially less flexible than the cover portion and that is attached to an edge of the cover portion, wherein the stile member is retained within the interior of the at least one coupler by the at least one tab.

3. The chair component assembly of claim 2, wherein the at least one coupler is integral with the shell member.

4. The chair component assembly of claim 3, wherein the at least one tab is integral with the shell member.

5. The chair component assembly of claim 4, wherein the at least one tab is flexibly resilient.

6. The chair component assembly of claim 4, wherein the at least one coupler and the at least one tab includes a plurality of couplers and tabs spaced about the peripheral edge of the shell member.

7. The chair component assembly of claim 5, wherein the at least one coupler includes a C-shaped cross-sectional configuration.

8. The chair component assembly of claim 1, wherein the at least one coupler is integral with the shell member.

9. The chair component assembly of claim 1, wherein the at least one tab is integral with the shell member.

10. The chair component assembly of claim 9, wherein the at least one tab is flexibly resilient.

11. The chair component assembly of claim 1, wherein the at least one coupler and the at least one tab includes a plurality of couplers and tabs spaced about a periphery of the shell member.

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

13. A chair component assembly, comprising:

a support component adapted to support a portion of a seated user and including a shell member having a channel and at least one fastener located within the channel; and

an upholstery cover assembly wrapped about at least a portion of the support component and including a drawstring located within a drawstring tunnel, wherein the drawstring is adapted to draw the upholstery cover assembly about the support component, wherein the drawstring and the drawstring tunnel are each retained within the channel by the at least one fastener.

14. The chair component assembly of claim 13, wherein the channel and the at least one fastener are each integral with the shell member.

15. The chair component assembly of claim 14, wherein the at least one fastener includes a plurality of cooperating teeth that secure the drawstring and the drawstring tunnel therebetween.

16. The chair component assembly of claim 15, wherein the chair component comprises a chair seat support.

17. The chair component assembly of claim 16, wherein the channel is downwardly opening.

18. A chair component assembly, comprising:

a support component adapted to support a portion of a seated user and including a shell member having an aperture;

an upholstery cover assembly wrapped about at least a portion of the support component and including a drawstring located within a drawstring tunnel, wherein the drawstring is adapted to draw the upholstery cover assembly about the support component, and wherein the drawstring includes at least one free end; and

at least one fastener engaging the aperture of the shell member and securing at least a portion of the at least one free end of the drawstring within the aperture.

19. The chair component assembly of claim 18, wherein the aperture of the shell comprises a channel.

20. The chair component assembly of claim 18, wherein the at least one fastener includes a spring clip.

21. The chair component assembly of claim 20, wherein the at least one fastener comprises a U-shaped cross-sectional configuration.

22. The choir component assembly of claim 20, wherein the at least one fastener includes a pair of spring clips.

23. The chair component of claim 22, wherein the pair of spring clips secure a single free end of the at least one free end of the drawstring.

24. The chair component of claim 20, wherein the at least one free end of the drawstring includes a pair of free ends, and wherein the at least one spring clip includes a single spring clip that secures the pair of free ends.

25. The chair component assembly of claim 18, wherein the chair component comprises a chair seat support.

26. A chair component assembly, comprising:

a support component adapted to support a portion of a seated user and including a shell member having a channel extending about a majority of an outer periphery of the support component and at least one fastener located within the channel; and

an upholstery cover assembly wrapped about at least a portion of the support component and including a drawstring located within a drawstring tunnel, wherein the drawstring is adapted to draw the upholstery cover assembly about the support component, and wherein at least one of the drawstring and the drawstring tunnel are retained within the channel by the at least one fastener.
