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 spaced apart from the cushion and is detached from the cover and engages the frame 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, 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 layer proximate the first and second strap ends.

5. The seat assembly of claim 4 wherein the elastomeric strap layer is detached from the strap 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:

first and second bolster cushions;

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

a cover assembly including;

a first portion disposed proximate the first surface, the first portion having a first end and a second end disposed opposite the first end; and

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

wherein the sling extends along the second surface and is disposed between the first bolster cushion and the seat cushion and between the second bolster cushion and the seat cushion and provides a tensile force that stretches the first portion.

8. The seat assembly of claim 7 wherein the first and second bolster cushions are separated from the seat cushion.

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 that 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 layer 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;

a seat cushion disposed between the first and second bolster cushions, the seat cushion having a first side that faces toward a seat occupant and a second side disposed opposite the first side; and

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

wherein the bolster sling is disposed between the first bolster cushion and the seat cushion and between the second bolster cushion and the seat cushion and extends along the second side, wherein the bolster sling biases the first and second bolster trim covers toward each other in response to a sufficient load force.

15. The seat assembly of claim 14 wherein the first and second bolster trim covers are spaced apart from 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 16 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.
