Abstract

A rear-side reinforcement structure for a motor vehicle body includes at least one side member extending in vehicle longitudinal direction, a shock absorber reinforcement profile and an outer rear end reinforcement profile. The shock absorber reinforcement profile is connected to the side member with a lower front profile section located in travelling direction at the front. The shock absorber reinforcement profile is connected to the rear end reinforcement profile with a rear profile section that is spaced from the side member and facing a rear end of the body. The outer rear end reinforcement profile extends from the rear profile section of the shock absorber reinforcement profile to the side member and with a lower connection section is connected to the side member.

First claim

What is claimed is:

1. A rear-side reinforcement structure for a motor vehicle body comprising:
at least one side member extending in a vehicle longitudinal direction;
a shock absorber reinforcement profile connected to the side member, the shock absorber reinforcement profile including a lower front profile section and a rear profile section, the lower front profile section extending from the side member, the rear profile section spaced apart from the side member and extending toward a rear end of the motor vehicle body; and
an outer rear end reinforcement profile, wherein the rear end reinforcement profile is connected to the rear profile section;
wherein the outer rear end reinforcement profile extends from the rear profile section of the shock absorber reinforcement profile to the side member and is connected to the side member with a lower connection section; and
wherein the side member, the shock absorber reinforcement profile and the outer rear end reinforcement profile comprise a closed reinforcement frame, and wherein the reinforcement frame substantially extends in a plane formed by a vehicle vertical direction and the vehicle longitudinal direction.

2. The motor vehicle body according to claim 1 , wherein the shock absorber reinforcement profile comprises an L-shaped contour.

3. The motor vehicle body according to claim 1 , wherein the rear profile section of the shock absorber reinforcement profile is connected to a wheel housing.

4. The motor vehicle body according to claim 1 further comprising a rear wall extending in vehicle transverse direction, which extends over a rear-side end section of the at least one side member.

5. The motor vehicle body according to claim 4 , wherein the outer rear end reinforcement profile is connected to the rear wall.

6. The motor vehicle body according to claim 4 , wherein the rear wall comprises a rear wall reinforcement profile, which extends parallel to a rear end cross member, the profile cross section of which is closed off by the rear wall.

7. The motor vehicle body according to claim 6 , further comprising an inner side wall with a rear-side inner edge profile, which is connected to the rear end cross member and to the rear wall.

8. The motor vehicle body according to claim 7 , wherein the inner side wall comprises a connection section for a rear roof cross member which projects to the inside, in vehicle transverse direction.

9. The motor vehicle body according to claim 8 , wherein the rear roof cross member, the outer edge profile, the inner edge profile together with the rear wall and one of rear wall reinforcement profile and rear end cross member form a reinforcement ring enclosing a rear end opening.

10. The motor vehicle body according to claim 4 , further comprising an outer side wall with an outer edge profile.

11. The motor vehicle body according to claim 10 , wherein the outer side wall is connected to the rear wall with a lower end section of its outer edge profile.

12. A motor vehicle with a motor vehicle body according to claim 1 .

13. A rear-side reinforcement structure for a motor vehicle body comprising:
at least one side member extending in a vehicle longitudinal direction;
a shock absorber reinforcement profile connected to the side member, the shock absorber reinforcement profile including a lower front profile section and a rear profile section, the lower front profile section extending upward from a suspension spring plate, the rear profile section being spaced apart from the side member and extending toward a rear end of the motor vehicle body; and
an outer rear end reinforcement profile, wherein the rear end reinforcement profile is connected to the rear profile section;
wherein the outer rear end reinforcement profile extends from the rear profile section of the shock absorber reinforcement profile to the side member and is connected to the side member with a lower connection section.

14. The rear-side reinforcement structure of claim 13 , wherein the side member, the shock absorber reinforcement profile and the outer rear end reinforcement profile comprise a closed reinforcement frame.

15. The rear-side reinforcement structure of claim 14 , further comprising a rear wall extending in vehicle transverse direction, which extends over a rear-side end section of the at least one side member.

16. The rear-side reinforcement structure according to claim 15 , wherein the outer rear end reinforcement profile is connected to the rear wall.

17. The rear-side reinforcement structure according to claim 15 , wherein the rear wall comprises a rear wall reinforcement profile, which extends parallel to a rear end cross member, the profile cross section of which is closed off by the rear wall.

18. The rear-side reinforcement structure according to claim 17 , further comprising an inner side wall with a rear-side inner edge profile, which is connected to the rear end cross member and to the rear wall.

19. The rear-side reinforcement structure according to claim 18 , wherein the inner side wall comprises a connection section for a rear roof cross member which projects to the inside, in vehicle transverse direction.

20. The rear-side reinforcement structure according to claim 19 , wherein the rear roof cross member, the outer edge profile, the inner edge profile together with the rear wall and one of rear wall reinforcement profile and rear end cross member form a reinforcement ring enclosing a rear end opening.
