Abstract

A seating unit component assembly comprises a support component that includes a first surface adapted to abut a seated user, a second surface opposite the first surface, a first end surface, a second end surface opposite the first end surface, and a pair of side surfaces extending between the first and second end surfaces, and a cover having a plurality of sides that cooperate to form an interior space that receives the support component therein, wherein the cover includes a first portion comprising a non-fabric substantially flexible thermoplastic material covering at least a portion of at least one of the side surfaces of the support component, a second portion comprising a fabric covering at least a portion of the first surface and at least a portion of the first end surface of the support component, and a third portion comprising a substantially rigid overlay covering at least a portion of the second end surface and at least a portion of the second surface.

First claim

The invention claimed is:

1. A seating unit component assembly, comprising:
a support component adapted to support a portion of a seated user, the support component including a first surface adapted to abut a seated user, a second surface opposite the first surface, a first end surface, a second end surface opposite the first end surface, and a pair of side surfaces extending between the first and second end surfaces; and
a cover having a plurality of sides that cooperate to form an interior space that receives the support component therein, the cover comprising:

a first portion comprising a substantially flexible, elastically resilient material covering at least a portion of at least one of the side surfaces of the support component;
a second portion comprising a significantly flexible material having a flexibility that is greater than the flexibility of the first portion and covering at least a portion of the first surface and at least a portion of the first end surface of the support component; and
a third portion comprising a substantially rigid overlay, wherein the third portion is less flexible than the first portion, and wherein the third portion covers at least a portion of the second surface and at least a portion of the side surfaces of the support component.

2. The seating unit component assembly of claim 1 , wherein the third portion covers at least a portion of the second end surface of the support component.

3. The seating unit component assembly of claim 2 , wherein the corner comprises an angle of greater than or equal to about 90°.

4. The seating unit component assembly of claim 3 , wherein the support component comprises a seat assembly.

5. The seating unit component assembly of claim 1 , wherein the first portion covers at least a portion of the second end surface.

6. The seating unit component assembly of claim 1 , wherein the first portion covers at least a portion of the second end surface.

7. The seating unit component assembly of claim 1 , wherein at least a majority of at least one of side surfaces of the support component is covered by the third portion.

8. The seating unit component assembly of claim 1 , wherein the non-fabric substantially flexible thermoplastic material of the first portion comprises thermoplastic elastomer.

9. The seating unit component assembly of claim 1 , wherein first portion and the second portion of the cover cooperate to define a corner between the first surface and at least one of the side surfaces.

10. An office chair assembly that includes the seating unit component of claim 1 .

11. A seating unit component assembly, comprising:
a support component adapted to support a portion of a seated user, the support component including a first surface adapted to abut a seated user, a second surface opposite the first surface, a first end surface, a second end surface opposite the first end surface, and a pair of side surfaces extending between the first and second end surfaces; and
a cover having a plurality of sides that cooperate to form an interior space that receives the support component therein, the cover comprising:

a first portion comprising a substantially flexible first material and covering at least a portion of at least one of the side surfaces of the support component;
a second portion comprising a substantially flexible second material that is different than the first material and covering at least a portion of the first surface and at least a portion of the first end surface of the support component; and
a third portion comprising a substantially rigid overlay covering at least a portion of at least one of the side surfaces and at least a portion of the second surface, wherein the third portion of the cover is significantly offset from the first end surface of the support component.

12. The seating unit component assembly of claim 11 , wherein at least a majority of at least one of side surfaces of the support component is covered by the third portion.

13. The seating unit component assembly of claim 11 , wherein the non-fabric substantially flexible thermoplastic material of the first portion comprises thermoplastic elastomer.

14. The seating unit component assembly of claim 11 , wherein first portion and the second portion of the cover cooperate to define a corner between the first surface and at least one of the side surfaces.

15. The seating unit component assembly of claim 14 , wherein the corner comprises an angle of greater than or equal to about 90°.

16. The seating unit component assembly of claim 11 , wherein the support component comprises a seat assembly.

17. An office chair assembly that includes the seating unit component of claim 11 .

18. The seating unit component assembly of claim 1 , wherein the third portion covers at least a portion of the second end surface.

19. The seating unit component assembly of claim 1 , wherein the first portion covers at least a portion of the second end surface.

20. The seating unit component assembly of claim 1 , wherein the first portion covers at least a portion of the second end surface.
