Abstract

A floor module is provided for installation in the rear area of a motor vehicle. A rear area of the floor module facing the tail of the vehicle includes a first plastic composition, and a front area facing away from the tail includes a second plastic composition, wherein the first plastic composition imparts a higher elastic deformability to the rear area than to the front area.

First claim

What is claimed is:

1. A floor module configured to be installed in the rear section of a motor vehicle, the floor module comprising:
a base plate configured to be supported substantially horizontally in the rear section of the motor vehicle;
a rear wall that extends from the base plate, the rear wall configured to be disposed proximate a rear end of the vehicle, the rear wall having a first plastic composition; and
a front wall that extends from the base plate, the front wall spaced apart at a distance from the rear wall across the base plate, the front wall having a second plastic compositions;
wherein a first portion of the base plate and the rear wall cooperate to define a rear section of the floor module;
wherein a second portion of the base plate and the front wall cooperate to define a front section of the floor module; and
wherein the first plastic composition imparts a higher elastic deformability to the rear section than the second plastic composition imparts to the front section.

2. The floor module according to claim 1 , wherein the front section and the rear section are configured a single piece.

3. The floor module according to claim 1 , wherein the floor module comprises a trough.

4. The floor module according to claim 1 , wherein the base plate is substantially.

5. The floor module according to claim 4 , further comprising a horizontal mounting flange extending around the base plate.

6. The floor module according to claim 5 , further comprising at least one rib extending between a lower side of the mounting flange and an exterior side of one of the rear wall and the front wall, wherein the mounting flange is stiffened by the at least one rib.

7. The floor module according to claim 1 , wherein the front section comprises a receptacle configured to receive a vehicle battery.

8. The floor module according to claim 7 , further comprising a rib bordering the receptacle, wherein the rib protrudes upward from the front section of the floor module.

9. The floor module according to claim 7 , further comprising a projection bordering the receptacle from the side, wherein the projection protrudes upward from the front section of the floor module and receives a hook configured to encompass at least one side of the battery.

10. An assembly with a floor module according to claim 7 and further comprising a vehicle battery installed in the receptacle.

11. A motor vehicle with a floor module according to claim 1 , wherein the floor module comprises a front edge anchored to a central cross member of a vehicle body.

12. The motor vehicle according to claim 11 , wherein the front section of the floor module extends under the central cross member and a storage space is bordered from above by the central cross member and from below by the front section.

13. The motor vehicle according to claim 11 , wherein the floor module further comprises a rear edge anchored on a rear cross member of the vehicle body.

14. The motor vehicle according to claim 11 , further comprising a plurality of fasteners detachably anchoring the floor module to the vehicle body.

15. The floor module according to claim 1 , wherein the rear wall and the first portion of the base plate have the first plastic composition; and
wherein the front wall and the second portion of the base plate have the second plastic composition.

16. The floor module of claim 15 , further comprising a first side wall and a second side wall;
wherein the first side wall and the second side wall extend between the rear wall and the front wall on opposite sides of the base plate;
wherein a first rear section of the first side wall and a second rear section of the second side wall have the first plastic composition;
wherein the first rear section of the first side wall, the second rear section of the second side wall, the first portion of the base plate, and the rear wall cooperate to define the rear section of the floor module;
wherein a first front section of the first side wall and a second front section of the second side wall have the second plastic composition; and
wherein the first front section of the first side wall, the second front section of the second side wall, the second portion of the base plate, and the front wall cooperate to define the front section of the floor module.

17. The floor module of claim 16 , wherein a boundary is defined where the rear section attaches to the front section; and
wherein the boundary lies substantially within a plane and extends through the first side wall, the base plate, and the second side wall.
