Abstract

A vehicle body structure has a frame element extending forward a vehicle longitudinal direction relative to the vehicle. A wheel is rotatably supported to the frame element. A bumper is attached to a front portion of the frame element. The bumper has a lateral side portion extending in an outboard direction relative to the frame element. A first support bracket extends from the frame element. A floating energy transmitting element is attached to the first support bracket at a location outboard of and spaced apart from the frame element, adjacent to but spaced apart from the bumper, and forward of and spaced apart from the wheel. In response to an impact event with the bumper being contacted by another object at a location outboard of the frame element, the floating energy transmitting element is contacted by the bumper and is moved rearward contacting the wheel.

First claim

What is claimed is:

1. A vehicle body structure, comprising:
a frame element extending forward from a passenger compartment area of a vehicle and extending in a vehicle longitudinal direction relative to the vehicle;
a wheel rotatably supported to the frame element;
a bumper attached to a front portion of the frame element, the bumper having a lateral side portion extending in an outboard direction relative to the frame element;
a first support bracket extending from the frame element;
a floating energy transmitting element attached to the first support bracket at a location outboard of and spaced apart from the frame element, adjacent to but spaced apart from the bumper, and forward of and spaced apart from the wheel such that in response to an impact event with the bumper being contacted by another object at a location outboard of the frame element, the floating energy transmitting element is contacted by the bumper and is moved rearward contacting the wheel; and
a wheel well skirt supported to the frame element via a plurality of body structures, the wheel well skirt extending above the wheel and further connecting to a rearward portion of the floating energy transmitting element.

2. The vehicle body structure according to claim 1 , further comprising
a sill structure connected to the frame element, and
the floating energy transmitting element has a wheel contacting surface configured to direct movement of the wheel to the sill structure in response to the impact event.

3. The vehicle body structure according to claim 2 , wherein
the wheel contacting surface extends in a direction that is perpendicular to the vehicle longitudinal direction.

4. The vehicle body structure according to claim 2 , wherein
the wheel contacting surface defines an acute angle relative to the vehicle longitudinal direction such that in response to the impact event off-center steering of the wheel is restricted.

5. The vehicle body structure according to claim 2 , wherein
the wheel contacting surface defines an obtuse angle relative to the vehicle longitudinal direction such that in response to the impact event off-center steering of the wheel is restricted.

6. The vehicle body structure according to claim 1 , wherein the floating energy transmitting element is made of a foam material having a predetermined density attenuated for transmitting impact energy.

7. The vehicle body structure according to claim 1 , wherein
the first support bracket has an inboard end, a central portion and an outboard end, the inboard end being attached to the frame element, the outboard end being attached to the floating energy transmitting element, and the central portion defining an angle defined relative to the frame element that is between 30 and 50 degrees.

8. The vehicle body structure according to claim 1 , wherein
the lateral side portion of the bumper has a curved contour that covers and at least partially conceals an outboard surface of the floating energy transmitting element.

9. The vehicle body structure according to claim 1 , wherein
the wheel rotatably is supported to the frame element by a front wheel suspension assembly pivotally supported to the frame element rearward of the floating energy transmitting element.

10. The vehicle body structure according to claim 1 , further comprising
a fender stay supported to the frame element at a location above and rearward of the floating energy transmitting element, and
at least one strap element that extends downward from the fender stay attaching to a rearward portion of the floating energy transmitting element.

11. A vehicle body structure, comprising:
a frame element extending forward from a passenger compartment area of a vehicle and extending in a vehicle longitudinal direction relative to the vehicle;
a wheel rotatably supported to the frame element;
a bumper attached to a front portion of the frame element, the bumper having a lateral side portion extending in an outboard direction relative to the frame element;
a first support bracket extending from the frame element;
a floating energy transmitting element attached to the first support bracket at a location outboard of and spaced apart from the frame element, adjacent to but spaced apart from the bumper, and forward of and spaced apart from the wheel such that in response to an impact event with the bumper being contacted by another object at a location outboard of the frame element, the floating energy transmitting element is contacted by the bumper and is moved rearward contacting the wheel; and
a second support bracket having an inboard end, a first section and a second section, the inboard end being attached to front portion of the frame element adjacent to the bumper, the first section extending rearward from the inboard end, the second section extending from the first section in an outboard direction away from the frame element and the second section being attached to a forward surface of the floating energy transmitting element and the first support bracket.

12. The vehicle body structure according to claim 11 , wherein
the second support bracket includes a third section that extends in a rearward direction from the second section, the third section being attached to an outboard surface of the floating energy transmitting element.

13. A vehicle body structure, comprising:
a frame element extending forward from a passenger compartment area of a vehicle and extending in a vehicle longitudinal direction relative to the vehicle;
a sill structure connected to the frame element;
a wheel rotatably supported to the frame element forward of the sill structure;
a bumper attached to a front portion of the frame element, the bumper having a lateral side portion extending in an outboard direction relative to the frame element;
a first support bracket extending from the frame element;
a second support bracket having an inboard end, a first section and a second section, the inboard end being attached to front portion of the frame element adjacent to the bumper, the first section extending rearward from the inboard end, the second section extending from the first section in an outboard direction away from the frame; and
a floating energy transmitting element having a forward surface, a lateral outboard surface and a wheel contact surface facing rearward, the forward surface being attached to the first support bracket and the second section of the second support bracket at a location outboard of and spaced apart from the frame element, the floating energy transmitting element being located adjacent to but spaced apart from the bumper, and forward of and spaced apart from the wheel such that in response to an impact event with the bumper being contacted by another object at a location outboard of the frame element, the wheel contact surface of the floating energy transmitting element is moved rearward contacting the wheel via impact energy received from the bumper with the wheel contacting surface directing movement of the wheel in response to the impact event.

14. The vehicle body structure according to claim 13 , wherein
the second support bracket includes a third section that extends in a rearward direction from the second section, the third section being attached to an outboard surface of the floating energy transmitting element.

15. The vehicle body structure according to claim 14 , further comprising
a fender stay supported to the frame element at a location above and rearward of the floating energy transmitting element, and
at least one strap element that extends downward from the fender stay attaching to
