The invention relates to a roll-over protection system 1 for a motor vehicle, comprising two roll bars 5 and 6 arranged side by side, which are movable from a lowered, rest position into an extended, raised position. The roll bars are mounted to a transverse carrier 4, wherein each bar has a first and a second movable bar arm 7 which are connected to one another by their first ends 11 in a height-adjustable first articulation, and a second and third articulation (15 and 21, figure 3) via which the bar arms 9 are mounted on the transverse carrier 4. The second articulation is transversely displaceable along the transverse carrier. The transverse carrier may be a U section and the bar arms may have a closed cross-sectional profile. The second articulation may be formed on a sliding block 23, wherein the sliding block is guided along a path (17) in a guide way formed as a double or single guide. A locking device may be provided comprising a locking pawl S1. |
