Abstract

A vehicle seat may include a seat back having a frame, a trim cover disposed on the seat back that includes a deployment seam, and an air bag module having an inflator and an air bag. The air bag may be configured to be inflated by the inflator to sever and deploy through the deployment seam. The air bag module may include a mounting stud that extends through the frame, first and second mounting nuts threaded onto the mounting stud to secure the air bag module to the frame, and an air bag guide. The air bag guide may have a first end located adjacent to the deployment seam and a second end disposed opposite the first end. The second end may engage and be disposed between the first and second mounting nuts.

Claims (32)

1. A vehicle seat comprising:

a seat back having a frame;

a trim cover disposed on the seat back that includes a deployment seam;

an air bag module having an inflator and an air bag that is configured to be inflated by the inflator to sever and deploy through the deployment seam, the air bag module further including:

a mounting stud that extends through the frame;

first and second mounting nuts threaded onto the mounting stud to secure the air bag module to the frame; and

an air bag guide having a first end located adjacent to the deployment seam and a second end disposed opposite the first end that engages and is disposed between the first and second mounting nuts.

2. The vehicle seat of claim 1 wherein the second end further comprises a washer that is disposed between the first and second mounting nuts.

3. The vehicle seat of claim 2 wherein the second end wraps at least partially around the washer such that the washer is separated from the first and second mounting nuts by the second end.

4. The vehicle seat of claim 3 wherein the second end includes stitching that extends through the air bag guide to secure the washer to the second end.

5. The vehicle seat of claim 2 wherein the washer is spaced apart from the frame.

6. The vehicle seat of claim 1 further comprising a support frame disposed on the frame rearward of the air bag module, wherein the support frame has a free end and is configured such that the air bag guide is disposed between and engages the free end and the frame.

7. The vehicle seat of claim 6 wherein an end of the trim cover opposite from the deployment seam is mounted to the support frame.

8. The vehicle seat of claim 7 wherein the free end is disposed between the trim cover and the air bag guide.

9. The vehicle seat of claim 1 wherein the first nut engages the frame and the second nut is spaced apart from the frame.

10. A vehicle seat comprising:

a seat back having a frame;

a support frame disposed on the frame at a rear side of the seat back;

an air bag module having an inflator and an air bag that is configured to be inflated by the inflator to deploy outwardly from the vehicle seat, the air bag module further including:

a housing that receives the air bag;

a mounting stud that extends from the inflator through the housing and the frame; and

first and second mounting nuts threaded onto the mounting stud to secure the air bag module to the frame such that the first mounting nut engages the frame and the second mounting nut is spaced apart from the first mounting nut;

a trim cover that provides an exterior surface of the vehicle seat, the trim cover having first and second panels that are stitched together at a deployment seam that is configured to sever upon deployment of the airbag, the first panel having a first end disposed at the deployment seam and a second end that engages the support frame; and

an air bag guide disposed under the trim cover, the air bag guide having a first end disposed proximate the deployment seam and a second end disposed opposite the first end that is disposed between the first and second mounting nuts;

wherein the trim cover is spaced apart from the air bag guide where the support frame is disposed between the trim cover and the air bag guide and the air bag guide is not disposed between the housing and the frame.

11. The vehicle seat of claim 10 wherein the second end of the trim cover is coupled to the support frame with a threaded fastener.

12. The vehicle seat of claim 10 wherein the second end of the air bag guide comprises at least two panels wherein at least one panel is disposed between the first and second mounting nuts and the second panel is secured to the support frame and under the trim cover.

13. The vehicle seat of claim 10 wherein the support frame is spaced apart from the mounting stud.

14. The vehicle seat of claim 10 wherein the second end of the air bag guide further comprises a washer disposed between the first and second mounting nuts.

15. The vehicle seat of claim 14 wherein the second end of the air bag guide wraps around the washer such that the washer is spaced apart from the first and second mounting nuts.

16. The vehicle seat of claim 15 wherein the second end of the air bag guide includes a substantially linear stitch seam that couples the second end to itself to secure the washer.

17. The vehicle seat of claim 13 wherein the air bag guide is disposed underneath and engages the trim cover between the deployment seam and the air bag module, the trim cover is separated from the air bag guide by a seat pad in a region disposed rearward of the air bag module, and the air bag guide engages and is disposed between the trim cover and the frame proximate the support frame.
