Mounting system for connecting an upper body structure of a motor vehicle to a vehicle platform of the motor vehicle

1. A mounting system for connecting an upper body structure of a vehicle to a vehicle platform of the vehicle, the mounting system comprising:

a hollow pillar element configured to be arranged lengthwise along a vertical vehicle axis;

a fastening bracket configured to laterally embrace a lower end portion of the hollow pillar element and including fastening interfaces for affixing the fastening bracket to the hollow pillar element at the lower end portion;

a hollow clip-on connector configured to be arranged laterally along a longitudinal vehicle axis, wherein the hollow clip-on connector defining a mounting platform including:

a horizontal resting surface for the hollow pillar element to be arranged thereupon at a lower end portion thereof together with the fastening bracket; and

a vertical mating surface for abutting a corresponding mating surface of the fastening bracket,

wherein the fastening bracket has fastening interfaces for affixing the fastening bracket to the hollow clip-on connector at a mating surface thereof; and

a hollow side sill element configured to be arranged lengthwise along the longitudinal vehicle axis,

wherein the hollow side sill element is formed with mounting notches running lengthwise along the hollow side sill element to receive complementarily shaped clip arms formed at a lower side of the hollow clip-on connector for mounting the hollow clip-on connector on top of the hollow side sill element.

2. The mounting system of claim 1 , wherein the hollow pillar element is formed via extrusion along a longitudinal extension thereof.

3. The mounting system of claim 2 , wherein the fastening bracket is formed via extrusion and includes two separate bracket arms, each bracket arm configured to embrace one respective lateral half of the hollow pillar element at the lower end portion thereof.

4. The mounting system of claim 1 , wherein the fastening bracket is formed via extrusion and includes two separate bracket arms, each bracket arm configured to embrace one respective lateral half of the hollow pillar element at the lower end portion thereof.

5. The mounting system of the claim 1 , wherein the fastening interfaces of the fastening bracket include fastening holes for receiving fasteners.

6. The mounting system of claim 1 , wherein the hollow clip-on connector is formed via extrusion along a lateral extension thereof.

7. The mounting system of the claim 1 , wherein the hollow side sill element is formed via extrusion along a longitudinal extension thereof.

8. The mounting system of the claim 1 , wherein at least one of the hollow pillar element, the fastening bracket, the hollow clip-on connector and the hollow side sill element is made of aluminum.

9. The mounting system of the claim 1 , wherein a cross section of the hollow pillar element is in a shape of a trapezoid.

10. A vehicle including the upper body structure mounted to the vehicle platform with the mounting system of the claim 1 .

11. The vehicle of claim 10 , wherein the fastening bracket is adhesively fixed to the hollow pillar element.

12. The vehicle of claim 11 , wherein the fastening bracket is adhesively fixed to the hollow clip-on connector at the mating surface thereof.

13. The vehicle of claim 10 , wherein the fastening bracket is adhesively fixed to the hollow clip-on connector at the mating surface thereof.

14. The vehicle of claim 10 , wherein the hollow clip-on connector is riveted or screwed to the hollow side sill element at the clip arms.

15. The vehicle of claim 10 , wherein the hollow clip-on connector is adhesively fixed to the hollow side sill element.
