Abstract

A vehicle body structure for reinforcing a pop-up seat mounting part includes a pair of rear side members engaged with a floor panel of a vehicle body, the pair of rear side members being spaced apart from each other by a spacing distance, a transverse member having a length corresponding to the spacing distance between the pair of rear side members, the transverse member being connected at opposite ends thereof to ends of upper surfaces of the pair of rear side members, and a back panel in contact with one surface of the transverse member.

First claim

What is claimed is:

1. A vehicle body structure for reinforcing a pop-up seat mounting part, the vehicle body structure comprising:
a pair of rear side members engaged with a floor panel of a vehicle body, the pair of rear side members being spaced apart from each other by a spacing distance;
a transverse member having a length corresponding to the spacing distance between the pair of rear side members, the transverse member being connected at opposite ends thereof to ends of upper surfaces of the pair of rear side members;
a back panel in contact with one surface of the transverse member, wherein the back panel comprises an upper back panel and a lower back panel arranged in a height direction and wherein the upper back panel is engaged with the transverse member so as to form a closed cross-section; and
a middle stiffener disposed in a middle of the back panel wherein the middle stiffener is located inside the closed cross-section formed by the transverse member and the upper back panel.

2. The vehicle body structure of claim 1 , wherein each of the pair of rear side members has a U-shaped cross-section that is open in an outward direction of the vehicle body.

3. The vehicle body structure of claim 1 , wherein at least one of the upper back panel or the lower back panel is a tailor welded blank.

4. A vehicle body structure for reinforcing a pop-up seat mounting part, the vehicle body structure comprising:
a pair of rear side members engaged with a floor panel of a vehicle body, the pair of rear side members being spaced apart from each other by a spacing distance;
a transverse member having a length corresponding to the spacing distance between the pair of rear side members, the transverse member being connected at opposite ends thereof to ends of upper surfaces of the pair of rear side members;
a back panel in contact with one surface of the transverse member, wherein the back panel comprises an upper back panel and a lower back panel arranged in a height direction and wherein the upper back panel is engaged with the transverse member so as to form a closed cross-section;
a quarter panel disposed at an upper end of the transverse member;
a pair of first brackets connecting the transverse member and the quarter panel; and
a middle stiffener disposed in a middle of the back panel, wherein the middle stiffener is located inside the closed cross-section formed by the transverse member and the upper back panel.

5. The vehicle body structure of claim 4 , further comprising a pair of second brackets, each bracket of the pair of second brackets being in contact with one end of a respective one of the pair of first brackets and an upper surface of the transverse member and connecting the transverse member and the quarter panel.

6. The vehicle body structure of claim 5 , wherein each bracket of the pair of second brackets has a curvature such that a height thereof gradually decreases from a first end of the second bracket that is engaged with the quarter panel to a second end of the second bracket.

7. The vehicle body structure of claim 4 , wherein each of the pair of rear side members has a U-shaped cross-section that is open in an outward direction of the vehicle body.

8. A vehicle comprising:
a vehicle body comprising a floor panel and a tailgate;
a pair of rear side members engaged with the floor panel, the pair of rear side members being spaced apart from each other by a spacing distance;
a transverse member having a length corresponding to the spacing distance between the pair of rear side members, the transverse member being connected at opposite ends thereof to ends of upper surfaces of the pair of rear side members; and
a back panel in contact with one surface of the transverse member, wherein the back panel comprises an upper back panel and a lower back panel arranged in a height direction and wherein the upper back panel is engaged with the transverse member so as to form a closed cross-section; and
a pop-up seat mounted to the vehicle body; and
a middle stiffener disposed in a middle of the back panel, wherein the middle stiffener is located inside the closed cross-section formed by the transverse member and the upper back panel.

9. The vehicle of claim 8 , wherein each of the pair of rear side members has a U-shaped cross-section that is open in an outward direction of the vehicle.

10. The vehicle of claim 8 , wherein at least one of the upper back panel or the lower back panel is a tailor welded blank.

11. The vehicle of claim 8 , further comprising:
a quarter panel disposed at an upper end of the transverse member, wherein an inner surface of the tailgate is in contact with the quarter panel when the tailgate is in a closed state; and
a pair of first brackets connecting the transverse member and the quarter panel.

12. The vehicle of claim 11 , further comprising a pair of second brackets, each bracket of the pair of second brackets being in contact with one end of a respective one of the pair of first brackets and an upper surface of the transverse member and connecting the transverse member and the quarter panel.

13. The vehicle of claim 12 , wherein each bracket of the pair of second brackets has a curvature such that a height thereof gradually decreases from a first end of the second bracket that is engaged with the quarter panel to a second end of the second bracket.

14. The vehicle body structure of claim 2 , wherein at least one of the upper back panel or the lower back panel is a tailor welded blank.

15. The vehicle body structure of claim 4 , wherein at least one of the upper back panel or the lower back panel is a tailor welded blank.

16. The vehicle of claim 9 , wherein at least one of the upper back panel or the lower back panel is a tailor welded blank.

17. The vehicle of claim 9 , further comprising:
a quarter panel disposed at an upper end of the transverse member, wherein an inner surface of the tailgate is in contact with the quarter panel when the tailgate is in a closed state; and
a pair of first brackets connecting the transverse member and the quarter panel.

18. The vehicle of claim 17 , further comprising a pair of second brackets, each bracket of the pair of second brackets being in contact with one end of a respective one of the pair of first brackets and an upper surface of the transverse member and connecting the transverse member and the quarter panel.

19. The vehicle of claim 18 , wherein each bracket of the pair of second brackets has a curvature such that a height thereof gradually decreases from a first end of the second bracket that is engaged with the quarter panel to a second end of the second bracket.
