Abstract

A seat assembly having a trim cover assembly disposed proximate a cushion. The trim cover assembly includes a first portion and a second portion. The second portion has a first end coupled to the first portion, a second end coupled to the frame, and an elastomeric layer that exerts a tensile force.

Claims

1. A seat assembly comprising:

a frame;

a cushion disposed proximate the frame; and

a cover assembly disposed proximate the cushion, the cover assembly including;

a first portion having a plurality of layers; and

a second portion having a first end coupled to the first portion and a second end coupled to the frame, the second portion having a cover and an elastomeric layer;

wherein the elastomeric layer is detached from the cover between the first and second ends.

2. The seat assembly of claim 1 wherein the second portion is disposed proximate a back side of a seat bottom.

3. The seat assembly of claim 1 wherein at least a portion of the elastomeric layer and the cover are spaced apart from each other.

4. The seat assembly of claim 1 further comprising a bolster strap spaced apart from the second portion, wherein the bolster strap includes a strap cover layer having a first strap end coupled to the cover assembly, a second strap end coupled to the frame, and an elastomeric strap layer coupled to the strap cover proximate the first and second strap ends.

5. The seat assembly of claim 4 wherein the elastomeric strap layer is detached from the cover layer between the first and second ends.

6. The seat assembly of claim 4 wherein the elastomeric layer provides a greater tensile force than the elastomeric strap layer.

7. A seat assembly comprising:

a seat cushion that includes a first surface and a second surface disposed opposite the first surface; and

a cover assembly including;

a first portion disposed proximate the first surface; and

a sling coupled to the first portion and disposed proximate the second surface;

wherein the sling provides a tensile force that stretches the first portion.

8. The seat assembly of claim 7 wherein the first portion further comprises a first end and a second end disposed opposite the first end and wherein the sling is coupled to the first and second ends.

9. The seat assembly of claim 7 wherein the seat cushion is provided with a seat bottom configured to support a seat occupant.

10. The seat assembly of claim 7 wherein at least a portion of the sling and the seat cushion are spaced apart from a seat frame.

11. The seat assembly of claim 7 wherein the cover assembly further comprises a second portion coupled to the first portion, wherein the second portion is spaced apart from the sling and includes an elastomeric layer exerts a tensile force on the first portion in a different direction than the tensile force exerted by the sling.

12. The seat assembly of claim 11 wherein the seat assembly further comprises a frame and wherein the second portion further comprises a cover layer, a first end coupled to the first portion, and a second end coupled to the frame, wherein the elastomeric layer is detached from the cover between the first and second ends.

13. The seat assembly of claim 12 wherein the second portion further comprises first and second elastomeric layers, wherein the first and second elastomeric layers are spaced apart from each other and are not fixedly attached to the frame.

14. A seat assembly comprising:

first and second bolster cushions; and

a bolster cover assembly including a first bolster trim cover disposed on the first bolster, a second bolster trim cover disposed on the second bolster and spaced apart from the first bolster trim cover, and a bolster sling coupled to the first and second trim cover bolsters;

wherein the bolster sling biases the first and second bolster trim covers are toward each other in response to a sufficient load force.

15. The seat assembly of claim 14 further comprising a seat cushion disposed between the first and second bolster cushions, wherein the bolster sling extends under the seat cushion.

16. The seat assembly of claim 15 further comprising a first cover assembly disposed on the seat cushion, the first cover assembly including a first trim cover disposed on a first side of the seat cushion and a first sling disposed on a second side of the seat cushion disposed opposite the first side.

17. The seat assembly of claim 16 wherein the first sling and the bolster sling are disposed adjacent to each other.

18. The seat assembly of claim 16 wherein the first sling is disposed between the bolster sling and the seat cushion.

19. The seat assembly of claim 14 further comprising a frame, wherein the first sling and the bolster sling extend substantially parallel to each other.

20. The seat assembly of claim 15 wherein the first and second bolster cushions are part of the seat cushion.
