Abstract

A vehicle body structure includes a front side member, a body attachment structure and an off-center impact structure. The body attachment structure is attached to an outboard wall of the front side member along a front-section forward of an outboard opening and extends in an outboard direction from the front side member. The off-center impact structure has an elongated member with a straight portion that extends through the outboard opening and into a hollow interior of the front side member. The elongated member is fixedly coupled to the outboard wall of the front side member adjacent to, spaced apart from and rearward of the body attachment structure. In response to an impact event of an off-center impact test the body attachment structure deforms and moves into contact with the elongated member transferring impact force to the elongated member.

First claim

What is claimed is:

1. A vehicle body structure comprising:
a front side member having a front end arid a front-section extending rearward from the front end, the front side member defining a hollow interior and extending in a vehicle longitudinal direction, the front side member having an outboard wall and an inboard wall with an outboard opening extending through the outboard wall to the hollow interior;
a body attachment structure attached to the outboard wall of the front side member along the front-section forward of the outboard opening and extending in an outboard direction from the front side member; and
an off-center impact structure having an elongated member with a straight portion that extends through the outboard opening and into the hollow interior of the front side member, the elongated member being fixedly coupled to the outboard wall of the front side member adjacent to, spaced apart from and rearward of the body attachment structure such that in response to an impact event of an off-center impact test the body attachment structure deforms and moves into contact with the elongated member transferring impact force to the elongated member.

2. The vehicle body structure according to claim 1 , wherein
the elongated member includes the straight portion and a curved portion that define an overall J-shape as viewed from above, the curved portion being spaced apart from the outboard wall of the front side member.

3. The vehicle body structure according to claim 2 , wherein
the curved portion defines an end face perpendicular to the outboard wall of the front side member, the end face facing a rearward surface of the body attachment structure.

4. The vehicle body structure according to claim 2 , wherein
the straight portion of the elongated member extends in a direction that is perpendicular to the front side member proximate the outboard opening.

5. The vehicle body structure according to claim 4 , wherein
the elongated member extends outboard away from the outboard wall of the flout side member by a first distance, and
the body attachment structure extends outboard away from the outboard wall of the front side member by a second distance that is greater than the first distance.

6. The vehicle body structure according to claim 1 , wherein
the inboard wall of the front side member defines an inboard opening aligned with the outboard opening relative to a lateral direction of the front side member with the straight portion of the elongated member being fixedly coupled to the inboard wall proximate the inboard opening.

7. The vehicle body structure according to claim 6 , further comprising
a sleeve that extends through the outboard opening, the hollow interior and through the inboard opening of the front side member, the sleeve being fixedly attached to the outboard wall arid the inboard wall with the straight portion of the elongated member extending into the sleeve, the straight portion of the elongated member being directly attached to the sleeve.

8. The vehicle body structure according to claim 7 , wherein
the sleeve is welded to the outboard wall and welded to the inboard wall.

9. The vehicle body structure according to claim 8 , wherein
the straight portion of the elongated member is directly attached to the sleeve via removable fasteners.

10. The vehicle body structure according to claim 1 , wherein
the outboard wall of the front side member defines a first forward outboard opening extending through the outboard wall to the hollow interior, and
the off-center impact structure further includes a first forward elongated member that is linearly shaped defining a first end portion, a mid-section portion and a second end portion, the first end portion extending through the first forward outboard opening into the hollow interior of the front side member and being rigidly connected to the from side member forward of the body attachment structure, the mid-section portion being connected to the front side member at a location proximate the outboard wall, the second end portion extending in an outboard direction away from the outboard wall of the front side member such that in response to the impact event during the off-center impact test the mid-section of the first forward elongated member deforms with the second end portion moves rearward into contact with the body attachment structure.

11. The vehicle body structure according to claim 10 , wherein
the outboard wall of the front side member has a second forward outboard opening that extends to the hollow interior of the front side member and is located forward of the first forward outboard opening, and
the off-center impact structure further has a second elongated member that is linearly shaped defining a first end portion, a mid-section portion and a second end portion, the first end portion extending into the second forward outboard opening and into the hollow interior, the mid-section portion being coupled to the front side member proximate the second forward outboard opening and the second end portion extending in the outboard direction from the front side member such that in response to the impact event during the off-center impact test the second forward elongated member deforms with the second end portion of the second forward elongated member moving rearward into contact with the first elongated member structure.

12. The vehicle body structure according to claim 11 , wherein
in a non-impacted state the first forward elongated member is parallel to the second forward elongated member.

13. The vehicle body structure according to claim 11 , wherein
in a non-impacted state the elongated member extends outboard away from the outboard wall of the front side member by a first distance, and
in the non-impacted state the body attachment structure extends outboard away from the outboard wall of the front side member by a second distance that is greater than the first distance.

14. The vehicle body structure according to claim 13 , wherein
in the non-impacted state the first forward elongated member extends laterally outboard from the front side member by a third distance that is less than the second distance and greater than the first distance.

15. The vehicle body structure according to claim 14 , wherein
in the non-impacted state the second forward elongated member extends laterally outboard from the front side member by a fourth distance that is less than each of the first, second and third distances.

16. The vehicle body structure according to claim 11 , wherein
the inboard wall of the front side member defines a first forward inboard opening aligned with the first forward outboard opening relative to a lateral direction of the front side member with the first end portion of the first forward elongated member being fixedly coupled to the inboard wall proximate the first forward inboard opening; and
the inboard wall of the front side member defines a second forward inboard opening aligned with the second forward outboard opening relative to the lateral direction of the front side member with the first end portion of the second forward elongated member being fixedly coupled to the inboard wall proximate the second forward inboard opening.

17. The vehicle body structure according to claim 16 , further comprising
a first forward sleeve that extends through the first forward outboard opening, the hollow interior and through the first forward inboard opening, the first forward sleeve being fixedly attached to the outboard wall and the inboard wall with the first end portion of the first forw
