Air bag chute attachment
View Patent ↗An air bag chute directs the deployment of an air bag from an air bag housing mounted on a seat frame through a separable seam sewn between inboard and outboard seat cover panels. An air bag housing is box shaped with a base wall mounted on the seat frame and rear, front, and end walls extending from the base wall and a cover wall. An inboard chute panel and an outboard chute panel each have inner ends attached to the air bag housing and outer ends attached to the inboard and outboard seat cover panels adjacent to the separable seam. The attachment of the inner ends of the inboard and outboard chutes to the air bag housing is provided on the walls of the housing with the inner ends spaced from one another.
1. An air bag chute apparatus for directing the deployment of an air bag from an air bag housing mounted on a seat frame and hidden in a seat cushion for deployment through a separable seam sewn between inboard and outboard seat cover panels comprising:
an air bag housing being generally box shaped with a base wall mounted on the seat frame and rear front, and end walls extending from the base wall and a cover wall and wherein at least one wall is mounted on the seat frame and at least one wall defines an opening through which the air bag deploys upon inflation thereof;
an inboard chute panel that has an inner end attached to the air bag housing and an outer end attached to the inboard seat cover panel adjacent the seam;
an outboard chute panel that has an inner end attached to the air bag housing and an outer end attached to the outboard seat cover panel adjacent to the seam;
said attachment of the inner ends of the inboard ends of the inboard and outboard chutes to the air bag housing being on the walls of the housing with the inner ends spaced from one another, and the inboard chute panel having the inner end captured between the housing base wall and the seat frame and attached thereto by an air bag assembly stud, and the outboard chute having its inner end attached to a different wall of the housing that is not bolted to the seat frame.
2. An air bag chute apparatus for directing the deployment of an air bag from an air bag housing mounted on a seat frame and hidden in a seat cushion for deployment through a separable seam sewn between inboard and outboard seat cover panels comprising:
an air bag housing being generally box shaped with a base wall mounted on the seat frame and rear front, and end walls extending from the base wall and a cover wall and wherein at least one wall is mounted on the seat frame and at least one wall defines an opening through which the air bag deploys upon inflation thereof;
an inboard chute panel that has an inner end attached to the air bag housing and an outer end attached to the inboard seat cover panel adjacent the seam;
an outboard chute panel that has an inner end attached to the air bag housing and an outer end attached to the outboard seat cover panel adjacent to the seam;
said attachment of the inner ends of the inboard ends of the inboard and outboard chutes to the air bag housing being on the walls of the housing with the inner ends spaced from one another, and at least one of the inboard chute panel and the outboard chute panel attaches around the air bag housing studs and is captured between the seat frame and the air bag housing.
3. The air bag chute apparatus of claim 2 where the other one of the inboard chute panel and the outboard chute panel attaches to hooks provided on the air bag housing.
4. The air bag chute apparatus of claim 2 where the other one of the inboard chute panel and the outboard chute panel has an attached strip that is utilized when making its attachment to the air bag housing.
5. The air bag chute apparatus of claim 2 where the other one of the inboard chute panel and the outboard chute panel snaps into the air bag housing.
6. The air bag chute apparatus of claim 2 where the other one of the inboard chute panel and the outboard chute panel nests within a depression on the air bag housing.
7. The air bag chute apparatus of claim 2 where the other one of the inboard chute panel and the outboard chute panel are attached to the air bag housing by protrusions.
8. The air bag chute apparatus of claim 2 where at least the other one of the inboard chute panel and the outboard chute panel are attached the housing by a bulbous end on one of the panel and the housing wall and a channel provided on the other of the panel and housing wall.
9. The air bag chute apparatus of claim 2 where the inboard chute panel and the outboard chute panel each have a top and a bottom and the panels are sewn together at one of the top and the bottom.
10. The air bag chute apparatus of claim 9 where the sewing is a tear seam.
11. The air bag chute apparatus of claim 9 where the sewing is a permanent seam.
12. The air bag chute apparatus of claim 9 where the sewing location is also near a second tear seam that enables the air bag to deploy through this location out of the seat cover between adjacent cover pieces when the second tear seam is fractured during deployment.
13. The air bag chute apparatus of claim 2 where an electrical connector attachment is made in the space between the inboard chute panel and the outboard chute panel.
14. The air bag chute apparatus of claim 2 where an electrical connector attachment is made in a space between panels of one of the inboard chute panel and the outboard chute panel.
15. An air bag chute apparatus for directing the deployment of an air bag from an air bag housing mounted on a seat frame and hidden in a seat cushion for deployment through a separable seam sewn between inboard and outboard seat cover panels comprising:
an air bag housing being generally box shaped with a base wall and rear, front, and end walls extending from the base wall where at least one wall is mounted to the seat frame and at least one wall defines an opening through which the air bag deploys upon inflation thereof;
an inboard chute panel that has an inner end attached to the air bag housing and an outer end attached to the inboard seat cover panel adjacent the seam;
an outboard chute panel that has an inner end attached to the air bag housing and an outer end attached to the outboard seat cover panel adjacent to the seam;
said attachment of the inner ends of the inboard ends of the inboard and outboard chutes to the air bag housing being on different walls of the housing so that the inner ends are spaced from one another, said inboard chute panel having the inner end attached to the wall of the housing that is bolted to seat frame by capturing the inner end of the inboard chute between the housing and the seat frame and the inner end of the outboard chute is attached to a different wall of the housing that is not bolted to the seat frame, said outboard chute panel attaching to hooks provided on the air bag housing.
16. The air bag chute apparatus of claim 15 where the inboard chute panel and the outboard chute panel each have a top and a bottom and the panels are sewn together at one of the top and the bottom.
17. The air bag chute apparatus of claim 16 where the sewing is a tear seam.
18. The air bag chute apparatus of claim 16 where the sewing is a permanent seam.
19. The air bag chute apparatus of claim 16 where the sewing location is also near a second tear seam that enables the air bag to deploy through this location out of the seat cover between adjacent cover pieces when the second tear seam is fractured during deployment.
20. The air bag chute apparatus of claim 15 where an electrical connector attachment is made in the space between the inboard chute panel and the outboard chute panel.
