Abstract

A vehicle body, preferably for a motor vehicle with four wheels, includes two side members extending in the longitudinal direction of the vehicle, at least one support, which extends in the vehicle transverse direction between the two side members, and at least one molded foam part that reinforces the vehicle body. The foam part is arranged in a lateral structure of the vehicle body at the height level of the support.

First claim

What is claimed is:

1. A vehicle body for a motor vehicle, comprising:
two side members extending in a longitudinal direction of the vehicle;
at least one support extending in a transverse direction of the vehicle between the two sides members; and
at least one molded foam component that reinforces the vehicle body, the molded foam component being arranged laterally outside of a respective side member with respect to a transverse direction of the vehicle in a lateral structure of the vehicle body at a level of the support, wherein
a hardened foam completely fills a part of the side member and a part of the support.

2. The vehicle body according to claim 1 , wherein
viewed in the transverse direction of the vehicle, the part of the side member and the part of the support filled with the hardened foam, and the molded foam component, are aligned to provide a path of force through the molded foam component, the foam in the side member and the foam in the support.

3. The vehicle body according to claim 1 , wherein the at least one molded foam component is arranged in a door of the vehicle body.

4. The vehicle body according to claim 1 , wherein each face-side end of the support rests against an interior side of a respective one of the two side members.

5. The vehicle body according to claim 4 , wherein the hardened foam in the support extends to the face-side ends.

6. The vehicle body according to claim 1 , wherein the support is arranged higher than a floor pan of the vehicle body.

7. The vehicle body according to claim 6 , wherein the support extends under a rear seat bench of the motor vehicle.

8. The vehicle body according to claim 1 , wherein the support is constructed as a heel plate of the motor vehicle.

9. The vehicle body according to claim 1 , wherein the support and/or the two side members are produced of fiber-reinforced plastic material or as a sheet metal shell construction.

10. The vehicle body according to claim 9 , wherein the hardened foam and/or the molded foam component are produced of expanded polypropylene or polyurethane.

11. The vehicle body according to claim 1 , wherein the hardened foam and/or the molded foam component are produced of expanded polypropylene or polyurethane.

12. A vehicle body for a motor vehicle, comprising:
two side members extending in a longitudinal direction of the motor vehicle;
at least one support extending in a transverse direction of the motor vehicle between the two side members; and
at least one molded foam component that reinforces the vehicle body, the at least one molded foam component being arranged laterally outside of a respective side member with respect to a transverse direction of the vehicle in a lateral structure of the vehicle body at a level of the support, wherein
at least one of the two side members comprises several profiles,
at the level of the support, the profiles are at least partially filled with hardened foam, and/or
the support forms a profile and is at least partially filled with hardened foam.

13. The vehicle body according to claim 12 , wherein the at least one molded foam component is arranged in a door of the vehicle body.

14. The vehicle body according to claim 12 , wherein each face-side end of the support rests against an interior side of a respective one of the two side members.

15. The vehicle body according to claim 14 , wherein the hardened foam in the support extends to the face-side ends.

16. The vehicle body according to claim 12 , wherein the support is arranged higher than a floor pan of the vehicle body.

17. The vehicle body according to claim 12 , wherein the support is constructed as a heel plate of the motor vehicle.

18. The vehicle body according to claim 12 , wherein the support and/or the two side members are produced of fiber-reinforced plastic material or as a sheet metal shell construction.

19. A vehicle, comprising:
a vehicle body, comprising:
two side members extending in a longitudinal direction of the vehicle;
at least one support extending in a transverse direction of the vehicle between the two sides members; and
at least one molded foam component that reinforces the vehicle body, the molded foam component being arranged laterally outside of a respective side member with respect to a transverse direction of the vehicle in a lateral structure of the vehicle body at a level of the support, wherein
a hardened foam completely fills a part of the side member and a part of the support.
