Patent attributes
A side wall formed in one piece with an outer shell of a side sill from high-strength sheet steel is described. The side wall merges without gradation into the adjoining side sill in the region of at least one vehicle pillar, so that the sheet steel is subjected to significantly less strain. A side sill of shell construction for a motor vehicle is partially formed by a side wall which may be composed of high-strength sheet steel. The side sill includes, in one case, at least one inner shell and an outer shell which are connected to one another by upper and a lower flanges. The outer shell is formed by the lower section of a side wall to which an outer panel is attached for providing a downward extension, so that the inner shell and the outer panel are connected to one another in the lower flange, and the inner shell and the side wall are connected to one another in the upper flange.
