Rear floor structure for a motor vehicle

1. A rear floor structure for a motor vehicle, comprising:

rear wheel houses; and

two longitudinal girders extending between the rear wheel houses,

wherein each of the two longitudinal girders extend substantially linearly in a longitudinal direction of the motor vehicle and have hollow profiles defined by an upper wall and a lower wall, and

wherein each of the two longitudinal girders comprise:

a downwardly open pocket formed therein that is configured to receive a shock absorber, wherein the shock absorber that is received in each downwardly open pocket crosses an opening of the lower wall in order to be supported on the upper wall; and

a support wall that extends at least partially around the shock absorber, and that is incorporated between the upper wall and the lower wall of that longitudinal girder.

2. The rear floor structure according to claim 1 , wherein an area of each upper wall on which the shock absorber is supported is higher than adjacent areas of that upper wall.

3. The rear floor structure according to claim 1 , wherein an area of each upper wall on which the shock absorber is supported forms an apex of a bulge of the upper wall like at least a half cupola.

4. The rear floor structure according to claim 1 , wherein each of the two longitudinal girders extend substantially linearly in the longitudinal direction of the motor vehicle along recesses for the rear wheel houses.

5. The rear floor structure according to claim 1 , wherein each of the two longitudinal girders have a hat-shaped cross-section, wherein each hat-shaped cross-section opens toward one side at least in an area of one of the rear wheel houses.

6. The rear floor structure according to claim 5 , wherein each hat-shaped cross-section has two brim sections fastened to one of the rear wheel houses.

7. The rear floor structure according to claim 1 , wherein the two longitudinal girders are connected by a floor plate.

8. The rear floor structure according to claim 7 , wherein the floor plate extends at a height of the two longitudinal girders.

9. The rear floor structure according to claim 1 , wherein the two longitudinal girders are connected by a crossbar at a height of the downwardly open pocket.

10. A rear floor structure for a motor vehicle, comprising:

rear wheel houses; and

two longitudinal girders extending between the rear wheel houses,

wherein the two longitudinal girders each have:

hollow profiles having an upper wall and a lower wall; and

a downwardly open pocket formed therein that is configured to receive a shock absorber that crosses an opening of the lower wall in order to be supported on the upper wall.

11. The rear floor structure according to claim 10 , wherein an area of the upper wall on which each shock absorber is supported is higher than adjacent areas of the upper wall.

12. The rear floor structure according to claim 10 , wherein an area of the upper wall on which the shock absorber is supported forms an apex of a bulge of the upper wall like at least a half cupola.

13. The rear floor structure according to claim 10 , wherein the two longitudinal girders extend substantially linearly in a vehicle longitudinal direction between the rear wheel houses.

14. The rear floor structure according to claim 10 , further comprising:

a support wall that extends at least partially around the shock absorber and that engages the two longitudinal girders, wherein the support wall is incorporated between the upper wall and the lower wall of the two longitudinal girders.

15. A rear floor structure for a motor vehicle, comprising:

rear wheel houses; and

two longitudinal girders extending between the rear wheel houses,

wherein each of the two longitudinal girders comprise:

a hat-shaped cross-section open toward one side at least in an area of one of the rear wheel houses, wherein each hat-shaped cross-section has two brim sections fastened to one of the rear wheel houses; and

a downwardly open pocket formed therein that is configured to receive a shock absorber.
