Abstract

A collision countermeasure apparatus includes an impact absorbing body attached to an outboard side of a sub-frame and a rigid link. The rigid link is attached to the impact absorbing body at an outboard location and extends upward to an outer side of a frame rail. A frontal impact with a rigid barrier outboard of the frame rail drives the impact absorbing body into the link to force the link into the outer side of the frame rail. The force applied to the frame rail by the impact absorbing body laterally displaces the vehicle to reduce the extent of intrusion into the passenger compartment of the vehicle.

First claim

What is claimed is:

1. A collision countermeasure apparatus comprising:
an impact absorbing body attached to an outboard side of a sub-frame; and
a rigid link attached to the impact absorbing body at an outboard location and extending upward to an outer side of a frame rail, wherein a frontal impact with a rigid barrier outboard the frame rail drives the impact absorbing body into the rigid link to force the link into the outer side of the frame rail, wherein the impact absorbing body is a closed ring that defines a central opening.

2. The apparatus of claim 1 wherein the closed ring is a circular annulus.

3. A collision countermeasure apparatus comprising:
an impact absorbing body attached to an outboard side of a sub-frame; and
a rigid link attached to the impact absorbing body at an outboard location and extending upward to an outer side of a frame rail, wherein a frontal impact with a rigid barrier outboard the frame rail drives the impact absorbing body into the rigid link to force the link into the outer side of the frame rail;
a first leg extending upwardly and rearward from a top surface of the impact absorbing body to a bend,
a second leg extending laterally from the bend to the outer side of the frame rail; and
a plate attached to the second leg and abutting the frame rail to slide along the frame rail in a full-frontal collision.

4. The apparatus of claim 3 wherein the first leg is attached to the impact absorbing body to extend upward from a top surface of the impact absorbing body.

5. The apparatus of claim 1 wherein the frame rail is a first frame rail, the apparatus further comprising:
a second frame rail extending longitudinally and parallel to the first frame rail;
a second impact absorbing body attached to an outboard side of the sub-frame; and
a second rigid link attached to the second impact absorbing body at an outboard location and extending upward to an outer side of the second frame rail, wherein a frontal impact with a rigid barrier outboard the second frame rail drives the second impact absorbing body into the second rigid link to force the second rigid link into the outer side of the second frame rail.

6. The apparatus of claim 5 wherein the sub-frame is attached below the first frame rail and the second frame rail in a front portion of a vehicle.

7. The apparatus of claim 1 wherein the sub-frame is attached below the frame rail in a front portion of a vehicle.

8. The apparatus of claim 1 further comprises:
a vehicle supported by the frame rail, and wherein a force applied by the rigid link to the outer side of the frame rail deflects the vehicle in an inboard direction.

9. A vehicle structure comprising:
a pair of frame rails supporting a vehicle;
a sub-frame secured below the frame rails;
a pair of bodies each attached to one lateral side of the sub-frame, and
a pair of links each attached to one of the bodies and extending to a plate that slides along one frame rail in a full-frontal collision, the links are laterally driven into one of the frame rails in a laterally offset collision.

10. The vehicle structure of claim 9 wherein the pair of bodies are a pair of closed rings that define a central opening.

11. The vehicle structure of claim 10 wherein the pair of bodies are a pair of circular annuluses.

12. The vehicle structure of claim 9 wherein the pair of links each further comprise:
a first leg extending upwardly and rearward from a top surface of one of the pair of bodies to a bend, and
a second leg extending laterally from the bend to an outer side of one of the pair of frame rails.

13. The vehicle structure of claim 12 wherein the first leg extends upward from a top surface of one of the pair of bodies and is attached to one of the pair of bodies.

14. A vehicle structure comprising:
an annular ring attached to a sub-frame;
a link attached on a lower end to the annular ring and facing an outer wall of a frame rail on an upper end; and
a plate attached to the upper end of the link, wherein an impact force applied to the annular ring is transferred to the link to force the plate laterally into the frame rail.

15. The vehicle structure of claim 14 wherein the frame rail is laterally displaced when the plate is forced laterally into the frame rail.

16. The vehicle structure of claim 14 further comprising:
a vehicle body supported on the frame rail wherein the vehicle body is laterally displaced when the plate is forced laterally into the frame rail.

17. The vehicle structure of claim 14 wherein a frontal impact force applied to the frame rail causes the plate to slide along the frame rail.
