Abstract

A thoracic support assembly for a seat back of a seat assembly. The thoracic support assembly may include a cover and a thoracic support pad. The thoracic support pad may be movable with respect to the cover and may be configured to support at least a portion of a thoracic region of a user's spine.

First claim

What is claimed is:

1. A thoracic support assembly for a seat back of a seat assembly, the thoracic support assembly comprising:
a backing adapted to be disposed on the seat back, the backing having an upper end and a lower end disposed opposite the upper end;
a cover that is disposed proximate the backing;
a thoracic support pad that is moveably disposed between the backing and the cover;
a first adjustment strap that extends from the thoracic support pad toward the upper end; and
a second adjustment strap that extends from the thoracic support pad toward the lower end, wherein the second adjustment strap is elastic and has a first end that is fixedly disposed on the thoracic support pad and a second end that is fixedly disposed on the backing proximate the lower end;
wherein the first adjustment strap and the second adjustment strap cooperate to adjust a position of the thoracic support pad to support at least a portion of a thoracic region of a user's spine.

2. The thoracic support assembly of claim 1 further comprising an upper mounting feature that is disposed proximate the upper end of the backing and adapted to mount the thoracic support assembly to the seat back.

3. The thoracic support assembly of claim 2 wherein the first adjustment strap extends to the upper mounting feature.

4. The thoracic support assembly of claim 2 wherein the first adjustment strap includes a fastening element that is disposed proximate the upper mounting feature for inhibiting movement of the thoracic support pad.

5. The thoracic support assembly of claim 1 wherein the thoracic support pad includes a backing plate and a thoracic pad disposed on the backing plate, wherein the backing plate is disposed proximate the backing and the thoracic pad is disposed proximate the cover.

6. The thoracic support assembly of claim 5 wherein the first adjustment strap and the second adjustment strap extend from the backing plate.

7. The thoracic support assembly of claim 1 further comprising an intermediate layer that is disposed between the backing and the cover, wherein the intermediate layer cooperates with the cover to define a pocket that receives the thoracic support pad, wherein the pocket constrains movement of the thoracic support pad such that the thoracic support pad is configured to support the thoracic region and not support a lumbar region of the user's spine.

8. The thoracic support assembly of claim 7 wherein the intermediate layer is disposed between and spaced apart from the upper end and the lower end of the backing and fixedly coupled to the cover.

9. The thoracic support assembly of claim 7 wherein the first adjustment strap and the second adjustment strap extend between the cover and the intermediate layer.

10. The thoracic support assembly of claim 7 wherein the thoracic support pad includes a backing plate and a thoracic pad disposed on the backing plate, wherein the backing plate is moveably disposed on the intermediate layer.

11. The thoracic support assembly of claim 1 wherein the first adjustment strap is spaced apart from and does not engage the second adjustment strap.

12. A thoracic support assembly for a seat back of a seat assembly, the thoracic support assembly comprising:
a backing adapted to be disposed on the seat back, the backing having an upper end and a lower end disposed opposite the upper end;
a cover that is disposed proximate the backing;
a thoracic support pad that is moveably disposed between the backing and the cover;
a first adjustment strap that extends from the thoracic support pad toward the upper end; and
a second adjustment strap that extends from the thoracic support pad toward the lower end; and
an intermediate layer that is disposed between the backing and the cover, wherein the intermediate layer cooperates with the cover to define a pocket that receives the thoracic support pad;
wherein the first adjustment strap and the second adjustment strap cooperate to adjust a position of the thoracic support pad to support at least a portion of a thoracic region of a user's spine and the first adjustment strap and the second adjustment strap extend between the cover and the intermediate layer.

13. The thoracic support assembly of claim 12 wherein the intermediate layer cooperates with the cover to define a pocket that receives the thoracic support pad, wherein the pocket constrains movement of the thoracic support pad such that the thoracic support pad is configured to support the thoracic region and not support a lumbar region of the user's spine.

14. The thoracic support assembly of claim 12 wherein the first adjustment strap is spaced apart from and does not engage the second adjustment strap.

15. The thoracic support assembly of claim 12 wherein the thoracic support pad includes a backing plate and a thoracic pad disposed on the backing plate, wherein the backing plate is disposed proximate the backing and the thoracic pad is disposed proximate the cover.

16. The thoracic support assembly of claim 15 wherein the first adjustment strap and the second adjustment strap extend from the backing plate.

17. The thoracic support assembly of claim 12 wherein the thoracic support pad is completely disposed above a lumbar region of the user's spine.

18. The thoracic support assembly of claim 12 further comprising an upper mounting feature that is disposed proximate the upper end of the backing and adapted to mount the thoracic support assembly to the seat back.

19. The thoracic support assembly of claim 12 wherein the second adjustment strap is elastic and has a first end that is fixedly disposed on the thoracic support pad and a second end that is fixedly disposed on the backing proximate the lower end.

20. The thoracic support assembly of claim 12 wherein the first adjustment strap is spaced apart from and does not engage the second adjustment strap.
