Energy absorbing vehicle fender
View Patent ↗A fender for absorbing forces generated from an impact includes a depending attachment flange which comprises a vertically aligned section depending from an exterior portion of the fender and a horizontally aligned section depending from the vertically aligned section adapted for mounting to a vehicle wherein the vertically aligned section includes a plurality of contoured portions for enhancing the stiffness of the vertically aligned section.
1. A fender adapted for attachment to a vehicle for absorbing forces generated from an impact, said fender comprising a depending attachment flange, said attachment flange comprising a vertically aligned section depending from an exterior portion of said fender and a horizontally aligned section depending from said vertically aligned section at a juncture, said vertically aligned section including a plurality of contoured portions for enhancing the stiffness of the vertically aligned section, each of said contoured portions merging with said vertically aligned section and said horizontally aligned flange section to provide stiffening.
2. A fender according to claim 1 wherein the vertical height of the vertically aligned section 4 of the flange equal to or greater than about 60 millimeters.
3. A fender according to claim 1 wherein the height of said vertically aligned section is from about 60 to about 100 millimeters.
4. A fender according to claim 1 wherein at least a portion of the contoured portion extends over about two-thirds of the height of the vertically aligned section of the flange.
5. A fender according to claim 1 being adapted to mate with a hood wherein said fender includes an exteriorly facing portion having an aesthetic exterior surface, and recess portion extending away from the aesthetic exterior for the seating of said hood when said hood is in a closed position.
6. A fender according to claim 1 wherein said vertically aligned section is joined to said horizontally aligned section at a juncture to form said attachment flange.
7. A fender according to claim 1 being adapted to be mounted to a vehicle support member wherein said horizontally aligned section of said flange is adapted to be secured to a matching horizontally aligned surface of said support member.
8. A fender according to claim 1 wherein said fender consist substantially entirely of a plastic material.
9. A fender according to claim 1 wherein said fender consist substantially entirely of a thermoplastic material.
10. A fender according to claim 1 wherein said fender consist substantially entirely of a plastic material selected from the group consisting of a polycarbonate, copolyester carbonate, polyphenylene ether, polyurethane, polyethylene, polypropylene.
11. A fender according to claim 1 wherein said fender consist substantially entirely of a blend of a plastic material selected from the group consisting of a polycarbonate/polybutylene terephthalate blend, polyphenylene ether/high impact polystyrene blend, polycarbonate/acryconitrile-butadiene-styrene blend, and blends thereof.
12. A fender according to claim 1 comprising wherein the vertically aligned section of said attachment flange is adapted to crush upon a predetermined impact and provides dimensional stability for the said fender during normal use.
13. A fender according to claim 1 wherein said vertically aligned section comprises at least one contoured portion to provide for stiffening and resist forces in a lateral direction to said vertically aligned section.
14. A fender according to claim 1 wherein said contoured portion extends upwardly from the horizontally aligned section of said flange.
15. A fender according to claim 1 wherein said contoured portion includes and opening for reducing the stiffness of said contoured portion.
16. A fender according to claim adapted for attachment to a vehicle for absorbing forces generated from an impact according to claim 2 said fender consist essentially of a single integral unit of molded thermoplastic material.
