Abstract

A vehicle body with a shell-type design includes at least one lateral frame, a tailgate frame which is connected to a node of the vehicle body by the lateral frame, and a reinforcing component which extends from the tailgate frame into the lateral frame. The tailgate frame and the lateral frame are each composed of an upper shell and a lower shell, and the reinforcing component is arranged between the upper and lower shells of the tailgate frame and the lateral frame. A hinge reinforcement for a hinge of a tailgate is formed in the reinforcing component in the region of the tailgate frame.

First claim

What is claimed is:

1. A vehicle body of shell-type construction, comprising:
a lateral frame;
a tailgate frame which is connected at a node of the vehicle body to the lateral frame; and
one reinforcing component which extends from within the tailgate frame as far as into the lateral frame, wherein
the tailgate frame and the lateral frame are each assembled from an upper shell and a lower shell of the tailgate frame, and an upper shell and a lower shell of the lateral frame, respectively,
the reinforcing component is arranged between the upper and lower shells of the tailgate frame and of the lateral frame,
within the tailgate frame, a hinge reinforcement for a hinge of a tailgate is formed in the reinforcing component, and
the hinge reinforcement extends through a cavity formed between the upper and lower shells of the tailgate frame, and supports the upper shell of the tailgate frame against the lower shell of the tailgate frame.

2. The vehicle body according to claim 1 , wherein the lateral frame comprises:
a roof frame, and
a pillar, wherein
the roof frame and the pillar are each assembled from the upper shell and the lower shell of the lateral frame, and wherein the reinforcing component extends as far as into the roof frame and/or as far as into the pillar.

3. The vehicle body according to claim 1 , wherein the reinforcing component is welded, riveted, adhesively bonded and/or brazed to at least one of the upper shell or the lower shell of the tailgate frame.

4. The vehicle body according to claim 3 , wherein the reinforcing component is welded, riveted, adhesively bonded and/or brazed to at least one of the upper shell or the lower shell of the lateral frame.

5. The vehicle body according to claim 4 , wherein the reinforcing component is welded, riveted, adhesively bonded and/or brazed to at least one of an upper shell or a lower shell of a roof frame and/or a pillar forming the lateral frame.

6. The vehicle body according to claim 1 , wherein the reinforcing component is welded, riveted, adhesively bonded and/or brazed to at least one of an upper shell or a lower shell of a roof frame and/or a pillar forming the lateral frame.

7. The vehicle body according to claim 1 , wherein the reinforcing component is configured as a partition in the lateral frame, and
wherein the partition extends through a cavity formed between the upper and lower shells of the lateral frame in order to support the upper shell of the lateral frame in relation to the lower shell of the lateral frame.

8. The vehicle body according to claim 1 , wherein on the hinge reinforcement, the reinforcing component bears flat against an inner side of the upper shell of the tailgate frame.

9. The vehicle body according to claim 1 , wherein the reinforcing component is a single piece.

10. The vehicle body according to claim 1 , wherein the reinforcing component comprises a plurality of pieces that are fixedly and directly connected to one another.

11. The vehicle body according to claim 1 , further comprising at least one hinge for a tailgate, wherein the hinge is attached to the hinge reinforcement.

12. The vehicle body according to claim 1 , wherein the upper shells and the lower shells of the tailgate frame and the lateral frame, and the reinforcing component are formed of shaped metal sheets.

13. A motor vehicle, comprising:
a vehicle body with a shell-type construction;
a tailgate of the motor vehicle;
wherein the vehicle body comprises:
a lateral frame;
a tailgate frame which is connected at a node of the vehicle body to the lateral frame; and
one reinforcing component which extends from within the tailgate frame as far as into the lateral frame, wherein
the tailgate frame and the lateral frame are each assembled from an upper shell and a lower shell of the tailgate frame, and an upper shell and a lower shell of the lateral frame, respectively,
the reinforcing component is arranged between the upper and lower shells of the tailgate frame and of the lateral frame,
within the tailgate frame, a hinge reinforcement for a hinge of the tailgate is formed in the reinforcing component,
the hinge reinforcement extends through a cavity formed between the upper and lower shells of the tailgate frame, and supports the upper shell of the tailgate frame against the lower shell of the tailgate frame, and
the tailgate is connected to the hinge reinforcement via at least one hinge.

14. The motor vehicle according to claim 13 , wherein the motor vehicle is a four wheel motor vehicle.
