Abstract

A system for managing lateral loads in a vehicle includes a crossmember and one or more structures that may be deformable. The crossmember is arranged laterally spanning a first longitudinal frame member, arranged on a first side of the vehicle, and a second longitudinal frame member of the vehicle, arranged on a second side of the vehicle. The structure is affixed to one lateral side of the vehicle, arranged longitudinally forward of the crossmember, arranged laterally outside of the first frame member, and is configured to deform during a small overlap collision. The structure, when under load, is configured to apply a lateral force on an end of the crossmember to cause lateral displacement of the vehicle. A vehicle may include a structure on each side of the vehicle to generate lateral displacement of the vehicle away from a colliding rigid barrier.

Claims (53)

1. A system for managing lateral loads in a vehicle, the system comprising:

a crossmember arranged laterally spanning a first longitudinal frame member and a second longitudinal frame member, wherein the first longitudinal frame member is arranged on a first side of the vehicle, and wherein the second longitudinal frame member is arranged on a second side of the vehicle; and

a structure affixed to one lateral side of the vehicle, wherein:

the structure is arranged longitudinally forward of the crossmember,

the structure is arranged laterally outside of the first frame member, and

the structure is configured to deform during a small overlap collision and apply a lateral force on an end of the crossmember to cause lateral displacement of the vehicle.

2. The system of claim 1 , wherein the crossmember is rigidly affixed to the first longitudinal frame member and to the second longitudinal frame member.

3. The system of claim 1 , wherein the structure comprises a wedge comprising:

a first face arranged along a laterally outer edge of the first frame member; and

a second face arranged along a bumper system, wherein the first face and the second face are arranged at approximately 90° to each other.

4. The system of claim 3 , wherein the second face is configured to deflect towards the first face under the small overlap collision.

5. The system of claim 1 , wherein the crossmember extends through a first opening in the first longitudinal frame member and through a second opening in the second longitudinal frame member.

6. The system of claim 1 , wherein the end of the crossmember is angled such that the front length of the crossmember is shorter than the rear length.

7. A frame system of a vehicle, the frame system comprising:

a first longitudinal frame member arranged on a first side of the vehicle;

a second longitudinal frame member arranged on a second side of the vehicle;

a bumper system affixed to the first longitudinal frame member and the second longitudinal frame member, wherein the bumper system is configured to receive a small overlap collision;

a crossmember arranged laterally spanning the first longitudinal frame member and the second longitudinal frame member; and

a structure affixed to the first lateral side of the vehicle, wherein:

the structure is arranged longitudinally forward of the crossmember,

the structure is arranged laterally outside of the first frame member, and

the structure is configured to deform during a first mode of small overlap collision and apply a lateral force on a first end of the crossmember to cause lateral displacement of the vehicle.

8. The frame system of claim 7 , wherein the crossmember is rigidly affixed to the first longitudinal frame member and to the second longitudinal frame member.

9. The frame system of claim 7 , wherein the structure comprises a wedge comprises:

a first face arranged along a laterally outer edge of the first frame member; and

a second face arranged along a bumper system, wherein the first face and the second face are arranged at approximately 90° to each other.

10. The frame system of claim 9 , wherein the second face is configured to deflect towards the first face under the small overlap collision.

11. The frame system of claim 7 , wherein the crossmember extends through a first opening in the first longitudinal frame member and a through a second opening in the second longitudinal frame member.

12. The frame system of claim 7 , wherein the end of the crossmember is angled such that the front length of the crossmember is shorter than the rear length.

13. The frame system of claim 7 , wherein the structure is a first structure, the frame system further comprising a second structure affixed to the second side of the vehicle, wherein:

the second structure is arranged longitudinally forward of the crossmember;

the second structure is arranged laterally outside of the second frame member; and

the second structure is configured to deform during a second mode of small overlap collision to the second side and apply a lateral force on a second end of the crossmember to cause lateral displacement of the vehicle.

14. A vehicle comprising:
