View Patent ↗An adapter for a vehicle includes: an adapter body configured to bridge between a crush rail at a vehicle end and a back-up structure, the adapter body having a socket configured to receive and enclose four sides of the crush rail, the adapter body having a plug configured to fit into the back-up structure; and an opening in the adapter body configured to have a drive shaft extend through the adapter.
1. An adapter for a vehicle comprising:
an adapter body configured to bridge between a crush rail at a vehicle end and a back-up structure, the adapter body having a socket configured to receive and enclose four sides of the crush rail, the adapter body having a plug configured to fit into the back-up structure; and
an opening in the adapter body configured to have a drive shaft extend through the adapter.
2. The adapter of claim 1 , wherein the vehicle end is a vehicle front end, wherein the socket is forward facing, and wherein the plug is rearward facing.
3. The adapter of claim 1 , wherein the socket comprises first and second surfaces configured to abut respective portions of a rear end of the crush rail.
4. The adapter of claim 3 , wherein the second surface is positioned closer to the back-up structure than the first surface.
5. The adapter of claim 4 , wherein the crush rail has a cross section profile comprising first, second and third cells that are substantially square, and wherein the adapter is configured so that the first and second cells abut the first surface, and so that the third cell abuts the second surface.
6. The adapter of claim 4 , wherein the first surface has at least three side walls configured to abut the first and second cells.
7. The adapter of claim 6 , wherein the second surface has at least three side walls configured to abut the third cell.
8. The adapter of claim 3 , wherein the vehicle end is a vehicle front end, and wherein the first and second surfaces are forward facing.
9. The adapter of claim 1 , wherein the opening has a recess located downward of the drive shaft.
10. The adapter of claim 9 , wherein the recess extends below the crush rail.
11. The adapter of claim 1 , wherein the opening has a recess located between the drive shaft and the back-up structure.
12. The adapter of claim 11 , wherein the vehicle end is a vehicle front end, and wherein the recess is located rearward of the drive shaft.
13. The adapter of claim 11 , wherein the recess extends past the crush rail.
14. The adapter of claim 1 , wherein the plug has a cross section profile comprising octagons adjacent each other.
15. The adapter of claim 1 , wherein the plug has a cross section profile comprising a rectangle.
16. The adapter of claim 1 , made from cast aluminum.
17. The adapter of claim 1 , configured to deform in response to crushing of the crush rail.
18. The adapter of claim 1 , wherein the back-up structure comprises a torque box.
