ABSTRACT:
A roll bar for vehicles, especially motor vehicles, comprises two vertical segments mounted on opposite sides of the body which are connected together by at least one cross member. Each segment comprises, according to a preferred embodiment, two elements of the same profile which withstand deformations that increase the section modulus, said elements being formed by roll sections assembled to form a hollow member and connected to one another by welding, gluing, or the like. According to a particularly advantageous arrangement, each segment, as viewed in cross section, comprises two tubular structures that are joined to a common rib.
