Abstract

Bumpers and vehicles that include bumpers are disclosed herein. In one embodiment, a bumper includes a bumper beam assembly, the bumper beam assembly including a beam, the beam including a front side that is oriented to face forward in a vehicle longitudinal direction, a bumper extension portion that is coupled to the beam and positioned at an outboard end of the bumper beam assembly, the bumper extension portion including a front side that is oriented face forward in the vehicle longitudinal direction, a top side that is oriented transverse to the front side, and a bottom side that is oriented transverse to the front side, and a reinforcement bracket that is coupled to the bumper extension portion, where the reinforcement bracket includes a front side that extends across the front side of the bumper extension portion.

First claim

What is claimed is:

1. A bumper comprising:
a bumper beam assembly, wherein the bumper beam assembly extends in a vehicle lateral direction, the bumper beam assembly comprising:
a reinforcement beam that extends in the vehicle lateral direction, the reinforcement beam comprising:
a front side that is oriented to face forward in a vehicle longitudinal direction that is transverse to the vehicle lateral direction;
a top side that is oriented transverse to the front side; and
a bottom side that is oriented transverse to the front side;

a bumper extension portion that is coupled to the reinforcement beam and positioned at an outboard end of the bumper beam assembly, the bumper extension portion comprising:
a front side that is oriented face forward in the vehicle longitudinal direction;
a top side that is oriented transverse to the front side; and
a bottom side that is oriented transverse to the front side; and

a reinforcement bracket that is coupled to the bumper extension portion, wherein the reinforcement bracket comprises a front side that extends across the front side of the bumper extension portion.

2. The bumper of claim 1 , wherein the reinforcement bracket is coupled to an inboard end of the bumper extension portion.

3. The bumper of claim 1 , wherein at least a portion of the reinforcement beam is positioned within the bumper extension portion.

4. The bumper of claim 3 , wherein at least a portion of the reinforcement bracket overlaps the reinforcement beam in the vehicle lateral direction.

5. The bumper of claim 1 , wherein the bumper extension portion further comprises an outboard reinforcement that is positioned at an outboard end of the bumper extension portion.

6. The bumper of claim 1 , wherein the reinforcement bracket comprises a top side that extends across the top side of the bumper extension portion in the vehicle longitudinal direction.

7. The bumper of claim 6 , wherein the reinforcement bracket comprises a rear flange that extends upward from the top side of the reinforcement bracket and the rear flange is coupled to a flange of the bumper extension portion.

8. The bumper of claim 1 , wherein the reinforcement bracket comprises a bottom side that extends across the bottom side of the bumper extension portion.

9. A vehicle comprising:
a side support that extends in a vehicle longitudinal direction;
a bumper beam assembly that is coupled to the side support, wherein the bumper beam assembly extends in a vehicle lateral direction that is transverse to the vehicle longitudinal direction, the bumper beam assembly comprising:
a reinforcement beam that extends in the vehicle lateral direction, the reinforcement beam comprising:
a front side that is oriented to face forward in the vehicle longitudinal direction;
a top side that is oriented transverse to the front side; and
a bottom side that is oriented transverse to the front side;

a bumper extension portion that is coupled to the reinforcement beam and positioned at an outboard end of the bumper beam assembly, the bumper extension portion comprising:
a front side that is oriented to face forward in the vehicle longitudinal direction;
a top side that is oriented transverse to the front side; and
a bottom side that is oriented transverse to the front side; and

a reinforcement bracket that is coupled to the bumper extension portion, wherein the reinforcement bracket comprises a front side that extends across the front side of the bumper extension portion.

10. The vehicle of claim 9 , wherein the reinforcement bracket is coupled to an inboard end of the bumper extension portion.

11. The vehicle of claim 9 , wherein at least a portion of the reinforcement beam is positioned within an inboard end of the bumper extension portion.

12. The vehicle of claim 11 , wherein at least a portion of the reinforcement bracket overlaps the reinforcement beam in the vehicle lateral direction.

13. The vehicle of claim 9 , wherein the bumper extension portion further comprises an outboard reinforcement that is positioned at an outboard end of the bumper extension portion.

14. The vehicle of claim 13 , wherein the outboard reinforcement is positioned outboard of the side support in the vehicle lateral direction.

15. The vehicle of claim 9 , wherein at least a portion of the reinforcement bracket extends inboard of the side support in the vehicle lateral direction.

16. The vehicle of claim 9 , wherein the reinforcement bracket comprises a bottom side that extends across the bottom side of the bumper extension portion.

17. A vehicle comprising:
a side support that extends in a vehicle longitudinal direction;
a bumper beam assembly that is coupled to the side support, wherein the bumper beam assembly extends in a vehicle lateral direction that is transverse to the vehicle longitudinal direction, the bumper beam assembly comprising:
a reinforcement beam that extends in the vehicle lateral direction;
a bumper extension portion that is coupled to the reinforcement beam and positioned at an outboard end of the bumper beam assembly, the bumper extension portion comprising an inboard end and an outboard end that is positioned outboard of the inboard end in the vehicle lateral direction; and
a reinforcement bracket that is coupled to and positioned within the inboard end of the bumper extension portion.

18. The vehicle of claim 17 , further comprising an outboard reinforcement coupled to the outboard end of the bumper extension portion.

19. The vehicle of claim 18 , wherein at least a portion of the reinforcement bracket is positioned inboard of the side support in the vehicle lateral direction such that when the vehicle impacts a barrier in a flat frontal barrier impact, the reinforcement bracket resists deflection of the side support in the vehicle lateral direction.

20. The vehicle of claim 17 , wherein the bumper extension portion further comprises a front side and the reinforcement bracket comprises a front side that extends across the front side of the bumper extension portion.
