Claims
- 1. A method for manufacturing an automotive frame assembly, the method comprising the steps of:
providing an inner rail; providing a cross member having a first end and a second end; first fastening said first end of said cross member to said inner rail; providing an outer rail; and then fastening said outer rail to said inner rail.
- 2. The method as recited in claim 1 wherein the step of fastening said first end of said cross member to said inner rail comprises simultaneously accessing an exterior side and an interior side of said inner rail so as to employ a two-sided fastener.
- 3. The method as recited in claim 2 wherein the step of fastening said first end of said cross member to said inner rail comprises first tacking said first end to said inner rail and then employing said two-sided fastener to attach said first end to said inner rail.
- 4. The method as recited in claim 1 wherein the step of fastening said outer rail to said inner rail comprises simultaneously accessing an exterior side and an interior side of said inner rail so as to employ a two-sided fastener.
- 5. The method as recited in claim 4 wherein the step of fastening said outer rail to said inner rail comprises first tacking said outer rail to said inner rail and then employing said two-sided fastener to attach said outer rail to said inner rail.
- 6. The method as recited in claim 1 further comprising:
providing an opposing inner rail; first fastening said second end of said cross member to said opposing inner rail; providing an opposing outer rail; and then fastening said outer rail to said opposing inner rail.
- 7. The method as recited in claim 6 wherein the step of fastening said second end of said cross member to said opposing inner rail comprises simultaneously accessing an opposing exterior side and an opposing interior side of said opposing inner rail so as to employ a two-sided fastener.
- 8. The method as recited in claim 7 wherein the step of fastening said second end of said cross member to said opposing inner rail comprises employing said two-sided fastener to attach said first end to said opposing inner rail.
- 9. The method as recited in claim 6 wherein the step of fastening said opposing outer rail to said opposing inner rail comprises simultaneously accessing an opposing exterior side and an opposing interior side of said inner rail so as to employ a two-sided fastener.
- 10. The method as recited in claim 9 wherein the step of fastening said opposing outer rail to said opposing inner rail comprises employing said two-sided fastener to attach said opposing outer rail to said opposing inner rail.
- 11. The method as recited in claim 6 wherein at least one of said inner rail, said outer rail, said cross member, said opposing inner rail, and said opposing outer rail is made of an aluminum material.
- 12. A method for manufacturing an automotive frame assembly, comprising:
providing an inner rail; providing an opposing inner rail; providing a cross member having a first end and a second end; fastening said first end of said cross member to said inner rail; fastening said second end of said cross member to said opposing inner rail; providing an outer rail; providing an opposing outer rail; then fastening said outer rail to said inner rail; and then fastening said opposing outer rail to said opposing inner rail.
- 13. The method as recited in claim 12 further comprising: simultaneously accessing an exterior side and an interior side of at least one of said inner rail and said opposing inner rail.
- 14. An automotive frame assembly comprising:
an inner rail having an exterior side and an interior side; a cross member having a first end and a second end, said first end being fixedly coupled to said exterior side of said inner rail; an opposing inner rail having an opposing exterior side and an opposing interior side, said opposing exterior side being fixedly coupled to said second end of said cross member; an outer rail being fixedly coupled to said interior side of said inner rail; and an opposing outer rail being fixedly coupled to said opposing interior side of said opposing inner rail.
- 15. The method as recited in claim 14wherein at least one of said inner rail, said outer rail, said cross member, said opposing inner rail, and said opposing outer rail is made of an aluminum metal.
- 16. The automotive frame assembly as recited in claim 14 wherein at least one two-sided fastener is operatively applied to said exterior side and said interior side of said inner rail so as to fixedly couple thereto at least one of said first end of said cross member and said outer rail.
- 17. The automotive frame assembly as recited in claim 14 wherein at least one two-sided fastener is operatively applied to said opposing exterior side and said opposing interior side of said opposing inner rail so as to fixedly couple thereto at least one of said second end of said cross member and said opposing outer rail.
- 18. The automotive frame assembly as recited in claim 14 wherein a reinforcement is integrated within at least one of said interior side of said inner rail, said outer rail, said opposing interior side of said opposing inner rail, and said opposing outer rail.
- 19. The automotive frame assembly as recited in claim 14 wherein said outer rail has a lip extending therefrom for attaching to said interior side of said inner rail, said opposing outer rail has an opposing lip extending therefrom for attaching to said opposing interior side of said opposing inner rail.
- 20. The automotive frame assembly as recited in claim 15 wherein said first end and said second end of said cross member each have a flange extending therefrom for attaching to at least one of said exterior side of said inner rail and said opposing exterior side of said opposing inner rail.
