Vehicle seat assembly
View Patent ↗A vehicle seat assembly having a seat pad, a trim cover, an air bag module, and a pad shield. The air bag module has an air bag, an inflator, and a housing that receives the air bag when the air bag is in a stored condition. The pad shield extends at least partially around the housing. Inflation of the air bag forces the pad shield against the seat pad to inhibit the air bag from contacting at least a portion of the seat pad.
1. A vehicle seat assembly, comprising:
a frame;
a seat pad disposed proximate the frame;
an air bag module disposed proximate the frame, the air bag module having an air bag, an inflator adapted to provide an inflation gas to inflate the air bag from a stored condition to an inflated condition, wherein the air bag extends through a deployment path when in the inflated condition;
a trim cover disposed over the seat pad and including a seam through which the air bag deploys when inflated; and
a pad shield that has a distal end, the pad shield being detached from the trim cover and spaced apart from the seam such that the distal end is not disposed in the deployment path when the air bag is in the stored condition and the distal end is disposed in the deployment path when the air bag is in the inflated condition.
2. The vehicle seat assembly of claim 1 wherein the seam is disposed adjacent to a side of the seat pad and is configured to separate when the air bag is inflated.
3. The vehicle seat assembly of claim 1 wherein the distal end extends away from the seat pad when the air bag is in the stored condition.
4. The vehicle seat assembly of claim 1 wherein the distal end extends away from the seam when the air bag is in the stored condition and wherein the distal end extends toward the seam when the air bag is in the inflated condition.
5. The vehicle seat assembly of claim 1 wherein the distal end is positioned against the seat pad between the seam and a housing that receives the air bag when the air bag is in the stored condition upon inflation of the air bag.
6. The vehicle seat assembly of claim 1 wherein the pad shield includes a first portion disposed between a housing that receives the air bag and the seat pad and a second portion extending from the first portion that is disposed between the housing and the trim cover when the air bag is in the stored condition.
7. The vehicle seat assembly of claim 1 wherein the pad shield includes a fleece material.
8. The vehicle seat assembly of claim 1 wherein the trim cover and the seat pad cooperate to define the deployment path.
9. A vehicle seat assembly, comprising:
a frame;
a seat pad disposed proximate the frame;
a trim cover disposed over the seat pad;
an air bag module disposed proximate the frame, the air bag module having a housing that receives an air bag when the air bag is in a stored condition, the housing having a frangible portion that separates to facilitate deployment of the air bag; and
a pad shield that extends at least partially around the housing and is not disposed between the seat pad and the trim cover when the air bag is in the stored condition;
wherein the pad shield covers the frangible portion when the air bag is in the stored condition.
10. The vehicle seat assembly of claim 9 wherein the pad shield does not cover the frangible portion when the air bag is inflated.
11. The vehicle seat assembly of claim 9 wherein inflation of the air bag forces the pad shield against the seat pad to inhibit the air bag from contacting at least a portion of the seat pad.
12. The vehicle seat assembly of claim 9 wherein the frangible portion is disposed on a side of the housing disposed adjacent to the trim cover.
13. The vehicle seat assembly of claim 9 wherein the pad shield is spaced apart from the trim cover when the air bag is in the stored condition.
14. The vehicle seat assembly of claim 9 wherein at least a portion of the pad shield is generally U-shaped and extends around three sides of the housing when the air bag is in the stored condition.
15. The vehicle seat assembly of claim 9 wherein the housing surrounds the air bag when the air bag is in the stored condition.
16. A vehicle seat assembly, comprising:
a frame;
a cushion disposed proximate the frame;
a trim cover disposed over the cushion and including a seam adjacent a side of the cushion;
an air bag module including an air bag that is disposed in a housing when in a stored condition and an inflator configured to supply gas to the air bag, thereby facilitating deployment of the air bag; and
a pad shield having an end portion that is disposed in a first position that extends away from the seam when the air bag is in the stored condition and disposed in a second position that extends toward the seam and covers a portion of the cushion when the air bag in an inflated condition, wherein a portion of the cushion that is covered by the end portion when the end portion is in the second position contacts the trim cover when the end portion is in the first position.
17. The vehicle seat assembly of claim 16 further comprising a deployment path disposed between the trim cover and the cushion, wherein the end portion is located outside the deployment path when the air bag is in the stored condition and moves into the deployment path when the air bag is inflated.
18. The vehicle seat assembly of claim 16 wherein the pad shield is spaced apart from the seam.
19. The vehicle seat assembly of claim 16 wherein the end portion is spaced apart from the housing when the air bag is in the inflated condition.
20. The vehicle seat assembly of claim 16 wherein the end portion contacts the trim cover during inflation of the air bag and is spaced apart from the trim cover when the air bag is in the inflated condition.
