Abstract

A vehicle airbag support assembly comprises a vehicle cross-car beam and an airbag support structure. The vehicle cross-car beam includes rearward and forward surfaces facing rearward and forward directions of a vehicle. The airbag support structure includes a mounting portion, and elongated extension portion and a support portion. The mounting portion is fixedly coupled to the rearward surface of the vehicle cross-car beam. The elongated extension portion includes a first end fixedly coupled to the mounting portion and a second end spaced from the first end such that the first end is situated closer to the rearward surface than the forward surface and the second end extends beyond the forward surface. The support portion supports an airbag device and is fixedly coupled to the second end of the extension portion such that the support portion is situated closer to the forward surface than the rearward surface and is cantilevered.

Claims

1. A vehicle airbag support assembly comprising:

a vehicle cross-car beam having a rearward surface facing a rearward direction of a vehicle and a forward surface facing a forward direction of the vehicle; and

an airbag support structure comprising;

a mounting portion including a plurality of lateral extensions fixedly coupled to the rearward surface of the vehicle cross-car beam;

an elongated extension portion having a first end fixedly coupled to the mounting portion and a second end spaced from the first end such that the first end is situated closer to the rearward surface than the forward surface and the second end of the extension portion extends beyond the forward surface of the vehicle cross-car beam, and the lateral extensions extend toward opposite directions outwardly beyond a width of the elongated extension portion from opposite sides of the elongated extension portion; and

a support portion configured to support an airbag device, the support portion being fixedly coupled to the second end of the extension portion such that the support portion is situated closer to the forward surface than the rearward surface and is cantilevered with respect to the mounting portion.

2. The vehicle airbag support assembly according to claim 1, wherein

the mounting portion includes a mounting structure that defines a mounting aperture having a center axis that projects toward the second end of the elongated extension portion.

3. The vehicle airbag support assembly according to claim 1, wherein

the elongated extension portion defines a space that divides the elongated extension portion into first and second extension arms.

4. The vehicle airbag support assembly according to claim 3, wherein

the space extends in a longitudinal direction of the elongated extension portion to span the mounting portion and the support portion along a central section of the elongated extension portion.

5. The vehicle airbag support assembly according to claim 3, wherein

the first and second extension arms each have a respective U-shaped cross-section as viewed in a longitudinal direction of the elongated extension portion.

6. The vehicle airbag support assembly according to claim 1, wherein

the elongated extension portion includes at least two planar base flanges that extend from an upper surface of the elongated extension portion toward the vehicle cross-car beam and have curved edges that at least partially correspond to a radial contour of the vehicle cross-car beam.

7. The vehicle airbag support assembly according to claim 1, wherein

the elongated extension portion extends substantially perpendicular to a plane of the mounting portion.

8. The vehicle airbag support assembly according to claim 1, wherein

the first end of the elongated extension portion extends beyond the rearward surface of the vehicle cross-car beam.

9. The vehicle airbag support assembly according to claim 1, wherein

the support portion is situated entirely beyond the forward surface of the vehicle cross-car beam.

10. The vehicle airbag support assembly according to claim 1, wherein

the support portion defines an opening that is configured to receive a portion of the airbag device therein, the opening having a central axis that extends at an acute angle relative to a horizontal plane toward the rearward direction of the vehicle.

11. The vehicle airbag support assembly according to claim 1, wherein

the mounting portion includes a mounting structure that includes the lateral extensions and defines a plurality of mounting apertures that are disposed on opposite sides of the elongated extension portion, each of the mounting apertures having a respective center axis that projects toward the second end of the elongated extension portion.

12. The vehicle airbag support assembly according to claim 1, further comprising

a mounting bracket that couples the mounting portion of the airbag support structure to the vehicle cross-car beam, the mounting bracket at least partially conforming to a radial contour of the vehicle cross-car beam.

19. The vehicle airbag support assembly according to claim 1, wherein

a portion of the cross-car beam is disposed between the lateral extensions and the support portion.

13. A vehicle airbag support structure comprising:

a mounting portion configured to be fixedly coupled to a rearward surface of a vehicle cross-car beam that faces a rearward direction of a vehicle;

an elongated extension portion having a first end fixedly coupled to the mounting portion and a second end spaced from the first end such that, with the vehicle airbag support structure in an installed position, the first end is situated closer to the rearward surface than a forward surface of the vehicle cross-car beam that faces a forward direction of the vehicle and the second end of the extension portion extends beyond the forward surface, the mounting portion including a plurality of support flanges that extend from an upper surface of the elongated extension portion toward the vehicle cross-car beam and have curved edges that at least partially correspond to a radial contour of the vehicle cross-car beam; and

a support portion configured to support an airbag device, the support portion being fixedly coupled to the second end of the extension portion such that the support portion is situated closer to the forward surface of the vehicle cross-car beam than the rearward surface and is cantilevered with respect to the mounting portion;

the mounting portion including a mounting structure that defines a plurality of mounting apertures that are disposed on opposite sides of the elongated extension portion, each of the mounting apertures having a respective center axis that projects toward the second end of the elongated extension portion, and each of the support flanges further extending along a direction of the respective center axis of a respective one of the mounting apertures toward the support portion.

14. The vehicle airbag support structure according to claim 13, wherein

the elongated extension portion extends substantially perpendicular to a plane of the mounting portion.

15. The vehicle airbag support structure according to claim 13, wherein

the support portion is situated entirely beyond the forward surface of the vehicle cross-car beam.

16. A vehicle airbag support structure comprising:

a mounting portion configured to be fixedly coupled to a rearward surface of a vehicle cross-car beam that faces a rearward direction of a vehicle;

an elongated extension portion having a first end fixedly coupled to the mounting portion and a second end spaced from the first end such that, with the vehicle airbag support structure in an installed position, the first end is situated closer to the rearward surface than a forward surface of the vehicle cross-car beam that faces a forward direction of the vehicle, and the second end of the extension portion extends beyond the forward surface; and
