Abstract

A motor vehicle body includes a side sill and a pillar arranged on the side sill, which has a cross section with a first side and a following second side in a vehicle longitudinal direction. A cross member is attached to the side sill. A sill-side end section of the cross member includes a side wall following a first side wall of the end section in the vehicle longitudinal direction. The distance of the first side wall in the vehicle longitudinal direction towards the second side of the cross section of the pillar decreases in a vehicle transverse direction towards the side sill at least locally in regions. An upper cover wall is connected to a connection section of the cross member. The distance of the upper cover wall decreases in a vehicle vertical direction towards the pillar in the vehicle transverse direction at least locally in regions.

First claim

What is claimed is:

1. A vehicle body comprising:
a side sill;
a pillar arranged on the side sill having a cross section with a first side in a vehicle longitudinal direction and a second following side in the vehicle longitudinal direction; and
a cross member attached to the side sill and having an end section and a connection section attached to the end section, the end section including a connection section-side opposite a sill-side end section and an upper cover wall that connects the connection section-side and the sill-side end section, the upper cover wall including a flange that extends outwardly from the connection-section side, the flange having at least one wing received wholly within the connection section to connect the end section to the connection section, wherein a height of the end section decreases in a vehicle transverse direction from the side sill to the connection section.

2. The motor vehicle body according to claim 1 , wherein a width of the upper cover wall decreases in a vehicle longitudinal direction from the side sill to the connection section.

3. The motor vehicle body according to claim 2 , wherein at least one of the width and the height of the cross section of the end section increases in the vehicle transverse direction.

4. The motor vehicle body according to claim 2 , wherein the cross member is adjacent to a second cross member associated with a second pillar.

5. The motor vehicle body according to claim 2 , wherein a cross section of at least one of the end section and connection section comprises a U-shaped profile oriented perpendicularly to the vehicle transverse direction.

6. The motor vehicle body according to claim 2 , wherein the end section engages the connection section over a range between 20% and 80% of a length of the connection section.

7. The motor vehicle body according to claim 2 , wherein the end section has a second side wall that forms an angle relative to the vehicle transverse direction in a range between 10° and 60°.

8. The motor vehicle body according to claim 7 , wherein the end section has a first side wall that forms an angle relative to the vehicle transverse direction in a range between 0° and 10°.

9. The motor vehicle body according to claim 2 , wherein the end section comprises a bent sheet metal part.

10. The motor vehicle body according to claim 2 , wherein the end section comprises at least one face flange attached to the side sill.

11. The motor vehicle body according to claim 2 further comprising a floor panel, wherein the cross member is attached to the floor panel.

12. The motor vehicle body according to claim 2 , wherein the upper cover wall of the end section includes an elevation that is in contact with the connection section.

13. A method for producing a motor vehicle body comprising:
providing a side sill and a pillar arranged on the side sill having a cross section with a first side in a vehicle longitudinal direction and a second following side in the vehicle longitudinal direction;
providing an end section having a second side wall following a first side wall of the end section in the vehicle longitudinal direction, the end section including connection section-side opposite a sill-side end section and an upper cover wall that connects the connection section-side and the sill-side end section, the upper cover wall including a flange that extends outwardly from the connection-section side and an elevation, the flange having at least one wing;
connecting the end section to the side sill;
providing a connection member; and
connecting the connection section to the end section such that the at least one wing is received wholly within the connection section and the elevation is in contact with the connection section;
wherein a height of the end section decreases in a vehicle transverse direction from side sill to the connection section.

14. The method according to claim 13 ,
wherein a width of the upper cover wall decreases in a vehicle longitudinal direction from the side sill to the connection section.
