Abstract

A vehicle seatback assembly includes a cushion assembly having a seating surface. A back panel includes a first side portion, a second side portion, and a back portion. A first living hinge is disposed between the first side portion and back portion. A second living hinge is disposed between the second side portion and back portion. A frame is disposed between the back panel and the cushion assembly. A peripheral cushion structure supports a periphery of the cushion assembly. A closeout panel is coupled with the back panel and is disposed behind the cushion structure to define a peripheral gap between the closeout panel and the cushion structure that extends around the sides of said seatback assembly. A shingled portion of the closeout panel extends behind and couples with the back panel. An airbag is coupled with the frame and is configured to deploy between the closeout and back panels.

First claim

What is claimed is:

1. A vehicle seatback assembly comprising:
a cushion assembly having a seating surface;
a back panel having a first side portion, a second side portion, and a back portion, wherein a first living hinge is disposed between the first side portion and the back portion and a second living hinge is disposed between the second side portion and the back portion;
a frame disposed between the back panel and the cushion assembly;
a peripheral cushion structure supporting a periphery of the cushion assembly;
a closeout panel coupled with the back panel and disposed behind the peripheral cushion structure to define a peripheral gap between the closeout panel and the peripheral cushion structure that extends around sides of said seatback assembly;
a shingled portion of the closeout panel extending behind and coupling with the back panel; and
an airbag coupled with the frame and configured to deploy between the closeout panel and the back panel, wherein the second side portion and the second living hinge define a triangular section configured to flex away from the closeout panel when the airbag is deployed.

2. The vehicle seatback assembly of claim 1 , wherein the closeout panel defines an intermediate cavity.

3. The vehicle seatback assembly of claim 1 , wherein the closeout panel includes an upper recess configured to receive a head restraint.

4. The vehicle seatback assembly of claim 1 , wherein the closeout panel includes inner laterally-extending flanges configured to provide support proximate the shingled portion.

5. The vehicle seatback assembly of claim 1 , wherein an upper section of the closeout panel directly engages the back panel and is free of a shingled portion.

6. A vehicle seatback assembly comprising:
a seatback frame disposed between a back panel and a cushion assembly;
a peripheral cushion structure supporting a periphery of the cushion assembly;
a closeout panel coupled with the back panel and disposed behind the peripheral cushion structure to define a peripheral gap;
a shingled portion of the closeout panel concealed behind and coupled with the back panel; and
an airbag deployed between the closeout panel and the back panel, wherein the second side portion and the second living hinge define a triangular section configured to flex away from the back panel when the airbag is deployed.

7. The vehicle seatback assembly of claim 6 , wherein the back panel includes a first side portion, a second side portion, and a back portion, wherein a first living hinge is disposed between the first side portion and the back portion, and a second living hinge is disposed between the second side portion and the back portion.

8. The vehicle seatback assembly of claim 6 , further comprising:
a plurality of decoupling fasteners disposed on the back panel and configured to engage the shingled portion.

9. The vehicle seatback assembly of claim 6 , wherein the closeout panel defines an intermediate cavity.

10. The vehicle seatback assembly of claim 6 , wherein the closeout panel includes an upper recess configured to receive a head restraint.

11. The vehicle seatback assembly of claim 6 , wherein the closeout panel includes inner laterally-extending flanges configured to provide support proximate the shingled portion.

12. The vehicle seatback assembly of claim 6 , wherein an upper section of the closeout panel directly engages the back panel and is free of a shingled portion.

13. A vehicle seatback assembly comprising:
a seatback frame disposed between a back panel and a cushion assembly;
a peripheral cushion structure supporting a periphery of the cushion assembly;
a closeout panel coupled with the back panel and disposed behind the peripheral cushion structure to define a peripheral gap;
a shingled portion of the closeout panel defined by an engagement flange concealed behind and coupled with a complementary receiving flange of the back panel, wherein the closeout panel includes inner laterally-extending flanges that connect a front wall of the closeout panel with an offset portion of the closeout panel, the inner laterally-extending flanges being configured to provide support proximate the shingled portion; and
an airbag deployed between the closeout panel and the back panel.

14. The vehicle seatback assembly of claim 13 , a plurality of decoupling fasteners disposed on the back panel and configured to engage the shingled portion.

15. The vehicle seatback assembly of claim 13 , wherein the closeout panel defines an intermediate cavity.

16. The vehicle seatback assembly of claim 13 , wherein the closeout panel includes an upper recess configured to receive a head restraint.
