Abstract

A carrier for use in supporting a component in a vehicle structure in accordance with the present invention includes at least a pair of side rails each having a first end and an opposed second end. The first and second ends of the side rails are attached to the vehicle structure, and each side rail includes a predetermined bending location at a predetermined location between the first and second ends. The component is adapted to be attached to the side rails intermediate the predetermined bending location and the first end. The side rails are operable to bend about the predetermined bending location when an impact load is applied to the first end of the side rails.

Claims

1. A carrier for use in supporting a component in a vehicle structure, comprising:

at least a pair of side rails each having a first end and an opposed second end, with said first and second ends attached to the vehicle structure, and with each said side rail including a predetermined bending location at a predetermined location between said first and second ends, said component adapted to be attached to said side rails intermediate said predetermined bending location and said first end, said side rails operable to bend about said predetermined bending location when said vehicle structure crushes between said first ends and said second ends; and

a cross member extending between said first ends of said side rails.

2. The carrier according to claim 1 wherein said predetermined bending locations are structural notches formed intermediate said first and second ends.

3. The carrier according to claim 2 wherein said structural notches are substantially arcuate in cross section.

4. The carrier according to claim 1 wherein said component is attached to said carrier at at least one mounting location adjacent said first ends of said side rails.

6. The carrier according to claim 1 including at least one vertical support member attached to said cross member.

7. The carrier according to claim 1 including at least one frame attachment member attached to said cross member.

8. The carrier according to claim 1 including a perimeter rail assembly attached to said side rails intermediate said predetermined bending location and said first end, said perimeter rail assembly adapted to mount the component thereon.

9. The carrier according to claim 8 wherein said perimeter rail assembly includes a first side support having a rearward and a forward end, a second side support having a rearward and a forward end and spaced from the first side support, and a transverse front support connected between the first and seconds side supports adjacent to the forward ends.

10. The carrier according to claim 1 wherein said opposed ends of said side rails are attached to a vehicle frame rail.

21. The carrier according to claim 6 including a perimeter rail assembly attached to said side rails intermediate said predetermined bending location and said first end, said perimeter rail assembly adapted to mount the component thereon.

22. The carrier according to claim 21 wherein said perimeter rail assembly includes a first side support having a rearward and a forward end, a second side support having a rearward and a forward end and spaced from the first side support, and a transverse front support connected between the first and seconds side supports adjacent to the forward ends.

23. The carrier according to claim 7 including a perimeter rail assembly attached to said side rails intermediate said predetermined bending location and said first end, said perimeter rail assembly adapted to mount the component thereon.

24. The carrier according to claim 23 wherein said perimeter rail assembly includes a first side support having a rearward and a forward end, a second side support having a rearward and a forward end and spaced from the first side support, and a transverse front support connected between the first and seconds side supports adjacent to the forward ends.

25. A carrier for use in supporting a component in a vehicle structure, comprising:

at least a pair of side rails each having a first end and an opposed second end, with said first and second ends attached to the vehicle structure, and with each said side rail including a predetermined bending location at a predetermined location between said first and second ends, said component adapted to be attached to said side rails intermediate said predetermined bending location and said first end, said side rails operable to bend about said predetermined bending location when said vehicle structure crushes between said first ends and said second ends; and

a perimeter rail assembly attached to said side rails intermediate said predetermined bending location and said first end, said perimeter rail assembly adapted to mount the component thereon.

26. The carrier according to claim 25 wherein said predetermined bending locations are structural notches formed intermediate said first and second ends.

27. The carrier according to claim 26 wherein said structural notches are substantially arcuate in cross section.

28. The carrier according to claim 25 wherein said component is attached to said carrier at at least one mounting location adjacent said first ends of said side rails.

29. The carrier according to claim 25 wherein said perimeter rail assembly includes a first side support having a rearward and a forward end, a second side support having a rearward and a forward end and spaced from the first side support, and a transverse front support connected between the first and seconds side supports adjacent to the forward ends.

30. The carrier according to claim 25 wherein said opposed ends of said side rails are attached to a vehicle frame rail.
