Abstract

Abstract A roll-over protection arrangement is provided which comprises an approximately U-shaped roll-over bar which can be translationally moved upward and back and which, by means of its downwardly directed legs, is guided by means of guiding elements in a housing. By means of the effect of springs, the roll-over bar can be rapidly changed from its inoperative position which projects hardly beyond the vehicle railing into a supporting position which projects clearly upward beyond the vehicle railing. In order to reduce the overall weight of the installed components as well as of the installed ejecting springs, almost all parts of the roll-over protection arrangement, including at least the legs of the roll-over bar and guiding elements therefor are made of extruded profiles.
