First claim
Opening claim text (preview).
What is claimed is: 1. A front rail for a vehicle comprising: an elongated body having a first end adapted to couple with a bumper and a second end adapted to couple with a rocker panel; a portion of the elongated body adjacent the first end has a cross section with an overall dumbbell shape that includes a first and second portion separated by a narrowed portion; and a reinforcement member positioned in the narrowed portion of the dumbbell cross section. 2. The front rail for a vehicle of claim 1 , wherein the first and second portions of the dumbbell have a rectangular shape in cross section. 3. The front rail for a vehicle of claim 2 , wherein the rectangular shapes are of different sizes. 4. The front rail for a vehicle of claim 1 , wherein the reinforcement has a flattened Z shape in cross section. 5. The front rail for a vehicle of claim 4 , wherein a web of the Z shape is substantially perpendicular to legs of the Z shape. 6. The front rail for a vehicle of claim 5 , wherein the web, in cross section, has a flat and planar configuration. 7. The front rail for a vehicle of claim 5 , wherein the web, in cross section, has a tortuous configuration. 8. A front rail for a vehicle of claim 1 , wherein the front rail body includes two stamped pieces secured together. 9. A vehicle including a frame comprising: the frame having a pair of front rails, each front rail comprising: an elongated body having a first end adapted to couple with a bumper and a second end adapted to couple with a rocker panel; a portion of the elongated body adjacent the first end has a cross section with an overall dumbbell shape that includes a first and second portion separated by a narrow portion; and a reinforcement member positioned in the narrowed portion of the dumbbell cross section. 10. The vehicle including a frame of claim 9 , wherein the first and second portions of the dumbbell have a rectangular shape in cross section. 11. The vehicle including a frame of claim 10 , wherein the rectangular shapes are of different sizes. 12. The vehicle including a frame of claim 9 , wherein the reinforcement has a flattened Z shape in cross section. 13. The vehicle including a frame of claim 12 , wherein a web of the Z shape is substantially perpendicular to legs of the Z shape. 14. The vehicle including a frame of claim 13 , wherein the web, in cross section, has a flat and planar configuration. 15. The vehicle including a frame of claim 13 , wherein the web, in cross section, has a tortuous configuration. 16. The vehicle including a frame of claim 9 , wherein the front rail body includes two stamped pieces secured together.
