Abstract

A trim cover for use with a vehicle seat having an air bag includes an outer layer. The outer layer includes a front portion having first and second ends. The outer layer further includes first and second bolster portions connected to the first and second ends, respectively, and an intermediate portion connected to the first and second bolster portions at first and second bolster seams, respectively. The first bolster seam is configured to rupture upon deployment of the air bag. A first reinforcement panel is positioned adjacent the first bolster portion. The first reinforcement panel has a first end portion connected to the outer layer proximate the first end of the front portion, and a second end portion connected to the outer layer proximate the first bolster seam. A second reinforcement panel is positioned adjacent the intermediate portion. The second reinforcement panel has one end portion connected to the outer layer proximate the first bolster seam, and an opposite end portion connected to the outer layer proximate the second bolster seam. The reinforcement panels are configured to reinforce the outer layer during deployment of the air bag so that the air bag deploys through the first bolster seam.

9. The trim cover of claim 7 further comprising a fourth reinforcement panel positioned adjacent the front portion of the outer layer, the fourth reinforcement panel having one end portion connected to the outer layer proximate the first front seam, and an opposite end portion connected to the outer layer proximate the second front seam.

23. The trim cover of claim 1 wherein the second reinforcement panel extends laterally beyond each end of the front portion.

24. The trim cover of claim 1 wherein the second reinforcement panel extends between the bolster portions.

25. The trim cover of claim 1 wherein the second reinforcement panel extends behind the front portion.

10. A vehicle seat assembly comprising:

a frame;

an air bag connected to the frame; and

a trim cover surrounding the frame and the air bag, the trim cover including;

an outer layer including a front portion having first and second ends, the outer layer further including first and second bolster portions connected to the first and second ends, respectively, and an intermediate portion connected to the first and second bolster portions at first and second bolster seams, respectively, wherein the first bolster seam is configured to rupture upon deployment of the air bag;

a first reinforcement panel positioned adjacent the first bolster portion, the first reinforcement panel having a first end portion connected to the outer layer proximate the first end of the front portion, and a second end portion connected to the outer layer proximate the first bolster seam; and

a second reinforcement panel positioned adjacent the intermediate portion, the second reinforcement panel having one end portion connected to the outer layer proximate the first bolster seam, and an opposite end portion connected to the outer layer proximate the second bolster seam;

wherein the reinforcement panels reinforce the outer layer during deployment of the air bag so that the air bag deploys through the first bolster seam.

11. The Vehicle seat assembly of claim 10 wherein the second reinforcement panel extends laterally beyond each end of the front portion.

12. The vehicle seat assembly of claim 10 wherein the second reinforcement panel extends between the bolster portions.
