Abstract

Vehicle rollover protection system with a roll bar, whose top piece is rounded in a U-shape. Such top pieces are typically tubular and are made from pipe bending parts. In order to achieve a three-dimensional contour of the top piece with irregular cross section of its profile, the invention calls for at least the tubular top piece consisting of at least two axially divided partially tubular shells of sheet metal, joined to each other and having different geometrical shapes according to a nominal contour.
