Abstract

Dans un système de protection contre les tonneaux (2) selon l'invention, par exemple pour un cabriolet à quatre places, il est prévu derrière les dossiers des sièges arrière deux éléments d'appui (4) pouvant être déplacés en direction de l'axe vertical du véhicule (Z). Le système de protection contre les tonneaux (2) est relié dans sa zone d'extrémité droite et dans sa zone d'extrémité gauche, au moyen d'un élément de liaison (6) respectif, à la structure de carrosserie latérale du véhicule. Selon l'invention, les éléments d'appui (4) sont guidés directement dans les éléments de liaison (6). Dans la zone centrale du véhicule, les éléments de liaison (6) sont reliés les uns aux autres par une traverse (8). Les composants individuels (4, 6, 8, 10, 12) du système de protection contre les tonneaux (2) sont conçus de préférence sous forme de profilés extrudés. De ce fait, on obtient une structure simple et modulaire du système de protection contre les tonneaux (2) et de faibles coûts de fabrication.
