Abstract

A vehicle body structure includes a side sill formed of high strength steel and a seat cross-member formed of high strength steel. A floor pan is welded to at least one of the side sill and the seat cross-member. A flange includes a base extending from the seat cross-member and a tab extending from the base. The tab is spaced from the seat cross-member and is welded to the floor pan and the side sill.

First claim

What is claimed is:

1. A vehicle body structure comprising:
a side sill formed of high strength steel;
a seat cross-member formed of high strength steel; and
a floor pan welded to at least one of the side sill and the seat cross-member;
a flange including a base extending from the seat cross-member and a tab extending from the base, the tab being spaced from the seat cross-member and welded to the floor pan and the side sill.

2. The vehicle body structure as set forth in claim 1 wherein the floor pan is disposed between the tab and the side sill.

3. The vehicle body structure as set forth in claim 1 wherein the base of the flange is welded to the side sill.

4. The vehicle body structure as set forth in claim 1 wherein the flange is integrally formed with the seat cross-member.

5. The vehicle body structure as set forth in claim 1 wherein the tab extends from the base to an end spaced from the base.

6. The vehicle body structure as set forth in claim 5 wherein the tab is welded to the floor pan between the base and the end of the tab.

7. The vehicle body structure as set forth in claim 5 wherein the end of the tab is 15-18 mm from the base.

8. The vehicle body structure as set forth in claim 1 wherein the floor pan is formed of mild steel.

9. The vehicle body structure as set forth in claim 1 wherein the floor pan is formed of cold rolled steel.

10. The vehicle body structure as set forth in claim 1 wherein the floor pan is 0.6-0.7 mm thick.

11. The vehicle body structure as set forth in claim 1 wherein the side sill is formed of dual phase steel.

12. The vehicle body structure as set forth in claim 1 wherein the side sill is 1.25-1.75 mm thick.

13. The vehicle body structure as set forth in claim 1 wherein the seat cross-member is formed of dual phase steel.

14. The vehicle body structure as set forth in claim 1 wherein the seat cross-member is formed of high-strength low alloy steel.

15. The vehicle body structure as set forth in claim 1 wherein the seat cross-member is 1.0-1.3 mm thick.

16. The vehicle body structure as set forth in claim 1 wherein the side sill and the seat cross-member are formed of dual phase steel.

17. The vehicle body structure as set forth in claim 1 wherein the floor pan is 0.6-0.7 mm thick, the side sill is 1.25-1.75 mm thick, and the seat cross-member is 1.0-1.3 mm thick.

18. The vehicle body structure as set forth in claim 1 wherein the floor pan is formed of mild steel, and wherein the side sill and the seat cross-member are formed of dual phase steel.

19. The vehicle body structure as set forth in claim 1 wherein the flange is formed from the same type of material as the seat cross-member.

20. A vehicle body structure comprising:
a side sill formed of high strength steel and being 1.25-1.75 mm thick;
a seat cross-member formed of high strength steel and being 1.0-1.3 mm thick; and
a floor pan formed of mild steel and being 0.6-0.7 mm thick and being welded to at least one of the side sill and the seat cross-member;
a flange integrally formed with the seat cross-member, the flange including a base extending from the seat cross-member and a tab extending from the base, the tab being spaced from the seat cross-member and welded to the floor pan and the side sill.
