Abstract

A curtain airbag guide bracket includes an airbag guide configured to direct deployment of an airbag toward an interior of a vehicle. The airbag guide includes an inside surface positioned adjacent the airbag and an opposite outside surface positioned adjacent a vehicle panel. A connector is used to attach the airbag guide to the vehicle panel. The airbag guide bracket also includes a post located adjacent the outside surface of the airbag guide. The post has a first side and a second side. The second side of the post is positioned closer to the connector than the first side of the post. The post is disposed within an aperture formed in the vehicle panel, such that the first side of the post engages an edge of the aperture and the second side of the post is displaced away from the edge of the aperture.

Claims

1. An airbag bracket system comprising:

an airbag guide configured to direct deployment of an airbag toward an interior of a vehicle, the airbag guide including an inside surface positioned adjacent the airbag and an opposite outside surface configured to be positioned adjacent a vehicle panel;

a connector attaching the airbag guide to the vehicle panel;

a post located adjacent the outside surface of the airbag guide, the post including a first side and a second side, the second side positioned closer to the connector than the first side,

the post configured to be at least partially disposed within an aperture defined in the vehicle panel, wherein the first side of the post engages an edge of the aperture and the second side of the post is displaced away from the edge of the aperture.

2. The airbag bracket system of claim 1 further comprising a rib interconnecting the airbag guide to the post.

3. The airbag bracket system of claim 2, wherein a distance between the vehicle panel adjacent the aperture and the rib is greater than a minimum clearance between the airbag guide and the vehicle panel over a region extending from the connector to the post.

4. The airbag bracket system of claim 1, wherein the inside surface of the airbag guide defines a generally concave shape and the outside surface defines a generally convex shape.

5. The airbag bracket system of claim 1 further comprising an airbag positioned adjacent the airbag guide, the airbag guide including a lower guide wall extending below the airbag, wherein the post is spaced a first distance from the connector and the lower guide wall is spaced a second distance, the first distance being greater than the second distance.

6. The airbag bracket system of claim 1, wherein a distance between an end of the post and the edge of the aperture adjacent the first side of the post is greater than a distance between the end of the post and the edge of the aperture adjacent the second side of the post.

7. The airbag bracket system of claim 1, wherein the airbag guide includes an inclined surface positioned between the airbag and the post.

8. The airbag bracket system of claim 1, wherein the vehicle panel includes a dimpled region extending toward an interior region of the vehicle, an edge of the dimpled region engaging the first side of the post.

9. The airbag bracket system of claim 1, wherein the post is oriented relative to the connector such that a distance from the connector to the edge of the aperture adjacent the first side of the post is less than a distance from the connector to the first side of the post along a region extending from a location adjacent the aperture toward a passenger compartment of the vehicle.

10. The airbag bracket system of claim 1, wherein the first surface of the post is substantially smooth.

11. An airbag system comprising:

an airbag attached to a vehicle panel;

an airbag guide positioned between the airbag and the vehicle panel;

a connector attaching the airbag guide to the vehicle panel;

a post extending from the airbag guide and including a first side and a second side, the second side positioned closer to the connector than the first side,

the post configured to be at least partially disposed within an aperture formed in the vehicle panel such that the first side of the post engages an edge of the aperture.

12. The airbag system of claim 11, wherein the post is oriented relative to the connector such that a distance from the connector to the edge of the aperture adjacent the first side of the post is less than a distance from the connector to the first side of the post along a region extending from a location adjacent the aperture toward a passenger compartment of the vehicle.

13. The airbag system of claim 11, where the first surface of the post includes a substantially smooth surface over a region extending from a distal end of the post to a distance greater than a minimum clearance between the airbag guide and the vehicle panel over a region extending from the connector to the post.

14. The airbag system of claim 11 further comprising a rib interconnecting the airbag guide to the post.

15. The airbag system of claim 14, wherein a distance between the vehicle panel adjacent the aperture and the rib is greater than a minimum clearance between the airbag guide and the vehicle panel over a region extending from the connector to the post.

16. The airbag system of claim 11, wherein the vehicle panel includes a dimpled region extending toward an interior region of the vehicle, an edge of the dimpled region engaging the first side of the post.

17. The airbag system of claim 11, wherein a distance between an end of the post and the edge of the aperture adjacent the first side of the post is greater than a distance between the end of the post and the edge of the aperture adjacent the second side of the post.

18. The airbag system of claim 11, wherein the second side of the post is spaced from the edge of the aperture.
