Abstract

A seat assembly that may include a seat back, an airbag module having an airbag, and a reinforcement chute. The seat back may have a seat back frame that may have a side member. The reinforcement chute may be fixedly coupled to the side member above and below the airbag module.

First claim

What is claimed is:

1. A seat assembly comprising:
a seat back having a seat back frame that has a side member;
an airbag module disposed proximate the side member, the airbag module having an airbag and an inflator adapted to provide an inflation gas to inflate the airbag from a stored condition to an inflated condition;
a side trim panel that conceals the airbag module and provides an exterior surface of the seat back; and
a reinforcement chute that is fixedly coupled to the seat back frame above the airbag module and/or below the airbag module, wherein at least a portion of the reinforcement chute is disposed between the side trim panel and the airbag module, wherein the reinforcement chute includes a first panel that is disposed between the side trim panel and the airbag module and the first panel is held in tension against the airbag module to inhibit expansion of the reinforcement chute toward the side trim panel.

2. The seat assembly of claim 1 wherein the reinforcement chute is fixedly coupled to the side member at a location disposed forward of the airbag module.

3. The seat assembly of claim 1 wherein the reinforcement chute includes a hole that receives a fastener that fixedly couples the reinforcement chute to the side member.

4. The seat assembly of claim 3 wherein the reinforcement chute includes a reinforcement seam that extends around the hole.

5. The seat assembly of claim 3 wherein the reinforcement chute includes a first reinforcement panel that extends around the hole and is fixed to the first panel, wherein the first panel and first reinforcement panel cooperate to define the hole.

6. The seat assembly of claim 3 wherein the reinforcement chute includes a second panel that is disposed between the side member and the airbag module, wherein the first panel and the second panel cooperate to define the hole.

7. The seat assembly of claim 6 wherein the first panel is attached to the second panel with a first compression seam that is disposed above the airbag module and a second compression seam that is disposed below the airbag module.

8. The seat assembly of claim 7 wherein the first compression seam is disposed between the airbag module and an attachment point where the reinforcement chute is attached to the side member.

9. The seat assembly of claim 6 wherein the reinforcement chute includes a first reinforcement panel that is disposed on the first panel and a second reinforcement panel that is disposed on the second panel, wherein the first reinforcement panel and the second reinforcement panel extend around the hole such that the first panel, second panel, first reinforcement panel, and second reinforcement panel cooperate to define the hole.

10. A seat assembly comprising:
a seat back having a seat back frame that has a side member;
an airbag module disposed on the side member, the airbag module having an airbag and an inflator adapted to provide an inflation gas to inflate the airbag from a stored condition to an inflated condition;
a reinforcement chute that is fixedly coupled to the side member above the airbag module and below the airbag module, wherein the reinforcement chute includes:
a first panel that has a fold; and
an energy absorption member that secures the fold when the airbag is in the stored condition and that separates to permit the reinforcement chute to unfold when the airbag is inflated from the stored condition to the inflated condition; and

a side trim panel that provides an exterior surface of the seat back and that conceals the airbag module and the reinforcement chute when the airbag is in the stored condition, wherein the first panel is disposed between the side trim panel and the airbag module.

11. The seat assembly of claim 10 wherein the fold is disposed opposite the side member.

12. The seat assembly of claim 11 wherein the reinforcement chute includes a hole that receives a fastener that extends through the hole to fixedly couple the reinforcement chute to the side member and wherein the fold is disposed proximate the hole.

13. The seat assembly of claim 12 wherein the fold is disposed proximate the hole and the energy absorption member is a seam that extends through the fold when the airbag is in the stored condition and wherein the seam severs to permit the reinforcement chute to unfold when the airbag is inflated from the stored condition.

14. The seat assembly of claim 13 wherein the reinforcement chute is folded against itself at the fold and wherein the seam extends through the fold when the airbag is in the stored condition.

15. The seat assembly of claim 14 wherein the reinforcement chute includes a second fold that is disposed adjacent to the fold, wherein the second fold is folded against the fold and the seam extends through the fold and the second fold.

16. A seat assembly comprising:
a seat bottom;
a seat back that is pivotally disposed on the seat bottom and that has a seat back frame that has a side member that extends away from the seat bottom;
an airbag module disposed on the side member, the airbag module having an airbag and an inflator adapted to provide an inflation gas to inflate the airbag from a stored condition to an inflated condition;
a side trim panel that provides an exterior surface of the seat back and conceals the airbag module when the airbag is in the stored condition; and
a reinforcement chute that is fixedly coupled to the side member above the airbag module and below the airbag module, wherein the reinforcement chute is at least partially disposed between the side trim panel and the airbag module and is fixedly coupled to the side member below the airbag module via a mounting bracket wherein the reinforcement chute is folded to form a pocket that receives the mounting bracket.

17. The seat assembly of claim 16 wherein the reinforcement chute includes a first panel that is disposed between the side trim panel and the airbag module, wherein the first panel is held in tension against the airbag module to inhibit expansion of the reinforcement chute toward the side trim panel.

18. A seat assembly comprising:
a seat bottom;
a seat back that is pivotally disposed on the seat bottom and that has a seat back frame that has a side member that extends away from the seat bottom;
an airbag module disposed on the side member, the airbag module having an airbag and an inflator adapted to provide an inflation gas to inflate the airbag from a stored condition to an inflated condition;
a side trim panel that provides an exterior surface of the seat back and conceals the airbag module when the airbag is in the stored condition; and
a reinforcement chute that is fixedly coupled to the side member above the airbag module and below the airbag module, wherein the reinforcement chute is at least partially disposed between the side trim panel and the airbag module and is fixedly coupled to the side member below the airbag module via a mounting bracket that is disposed on the side member and includes a hook that extends away from the side member and wherein the reinforcement chute includes a mounting rod that engages the hook to couple the reinforcement chute to the mounting bracket.

19. The seat assembly of claim 18 wherein the reinforcement chute is folded to form a pocket that receives the mounting rod.

20. The seat assembly of claim 18 wherein the reinforcement chute includes a first panel that is disposed between the side trim panel and the airbag module, wherein the first panel is held in tension against the airbag mo
