Abstract
According to the invention, a side sill of a vehicle body of a motor vehicle comprises an outer shell and an inner shell connected to each other via flanges. A reinforcement is removably attached to the outside of the outer shell, which reinforcement extends essentially over the entire length of the side sill in the vehicle longitudinal direction. By means of this reinforcement, a load introduced onto a point of the side sill is absorbed and distributed. This is especially relevant to achieving better crash characteristics in a side pole crash.

A side sill for a vehicle body, comprising:
- an outer shell,
- an inner shell,
- a reinforcement extending in the vehicle longitudinal direction along the length of the side sill which reinforcement comprises a curved sheet metal profile and is removably attached to the outer shell by at least one of screws and rivets so as to increase the stiffness of the side sill and distribute a force acting on a point on a side of the side sill in a longitudinal direction, and
- a hat-shaped profile extending in the vehicle longitudinal direction and arranged between the outer shell and the inner shell,
- wherein upper and lower portions of the hat-shaped profile are attached to the inner shell and a middle area of the hat-shaped profile is attached to the outer shell.
A vehicle body of a motor vehicle comprising:
- a side sill comprising:
- an outer shell having an inset area on an outer surface of the outer shell,
- an inner shell attached to the outer shell,
- a hat-shaped profile arranged between the outer shell and the inner shell, such that an assembly of the outer shell, the inner shell, and the hat-shaped profile comprises at least three closed cavities,
- a reinforcement extending in the vehicle longitudinal direction between one of an A-column and a B-column of the vehicle and a rear area of a passenger compartment which reinforcement comprises a curved sheet metal profile and is removably attached to the outer shell by at least one of screws and rivets so as to distribute a force acting on a side of the side sill in longitudinal direction,
- wherein upper and lower portions of the hat-shaped profile are attached to the inner shell and a middle area of the hat-shaped profile is attached to the outer shell.
