Abstract

A vehicle structure comprising a body including a wheel house, a fender and an energy absorption member. The fender has an exposed A-side surface and an opposed B-side surface, with the fender including a laterally inner edge extending fore-and-aft that defines a portion of a hood opening, and the B-side surface adjacent to the laterally inner edge spaced from the wheel house in a vertical direction to define a crush gap. The energy absorption member is located in the crush gap between the wheel house and the fender, with the energy absorption member having a fender attachment flange secured to the B-side surface of the fender adjacent to the laterally inner edge, a body attachment flange secured to the wheel house, and an energy absorbing portion extending between the fender attachment flange and the body attachment flange, with the energy absorbing portion being curved in the vertical direction.

First claim

What is claimed is:

1. A vehicle structure comprising:
a body including a wheel house;
a hood having a hood side edge extending in a fore-and-aft direction;
a fender having an upper outer skin portion having an exposed A-side surface and an opposed B-side surface, the fender including a laterally inner edge extending in the fore-and-aft direction adjacent to the hood side edge, the laterally inner edge defining a portion of a hood opening within which the hood is mounted, the B-side surface adjacent to the laterally inner edge spaced from the wheel house in a vertical direction to define a crush gap, the fender also having a hood support extending from the upper outer skin portion laterally inboard under the hood and configured to continuously support the hood side edge in the vertical direction under vehicle operating conditions including during a pedestrian impact event on top of the hood or fender and when there is no pedestrian impact event;
at least one elastomeric support located under and contacting the hood and located above and contacting the hood support wherein the hood support supports the hood side edge via the at least one elastomeric support in the vertical direction under the vehicle operating conditions including during the pedestrian impact event and when there is no impact pedestrian event; and
an energy absorption member located in the crush gap between the wheel house and the fender, the energy absorption member having a fender attachment flange secured to the B-side surface of the fender adjacent to the laterally inner edge, a body attachment flange secured to the wheel house, and an energy absorbing portion extending between the fender attachment flange and the body attachment flange, the energy absorbing portion being curved in the vertical direction and be a single, monolithic piece that extends longitudinally along an entire length of a wheel house to fender upper outer skin portion interface;
wherein the energy absorption member is generally C-shaped, with the fender attachment flange extending inboard from the energy absorbing portion and the body attachment flange extending inboard from the energy absorbing portion.

2. A vehicle structure comprising:
a body including a wheel house;
a hood having a hood side edge extending in a fore-and-aft direction;
a fender having an upper outer skin portion having an exposed A-side surface and an opposed B-side surface, the fender including a laterally inner edge extending in the fore-and-aft direction adjacent to the hood side edge, the laterally inner edge defining a portion of a hood opening within which the hood is mounted, the B-side surface adjacent to the laterally inner edge spaced from the wheel house in a vertical direction to define a crush gap, the fender also having a hood support extending from the upper outer skin portion laterally inboard under the hood and configured to support the hood side edge in the vertical direction; and
an energy absorption member located in the crush gap between the wheel house and the fender, the energy absorption member having a fender attachment flange secured to the B-side surface of the fender adjacent to the laterally inner edge, a body attachment flange secured to the wheel house, and an energy absorbing portion extending between the fender attachment flange and the body attachment flange, the energy absorbing portion being curved in the vertical direction and being a single, monolithic piece that extends longitudinally along an entire length of a wheel house to fender upper outer skin portion interface, wherein the energy absorption member is generally C-shaped, with the fender attachment flange extending inboard from the energy absorbing portion and the body attachment flange extending inboard from the energy absorbing portion.
