Patent ID: 7946623

Claim:
A rollover protection system for a passenger vehicle, the roll over protection system comprising: at least one top unit having at least one substantially vertical beam or tube; and a connecting member provided at a top end of the at least one vertical beam or tube, wherein the at least one vertical beam or tube has a tapered section extending in a travel direction of the vehicle, the tapered section being located in an upper portion of the at least one vertical beam or tube so that, in the event of a crash, if the top unit gets hooked in soft soil or against solid objects or otherwise is subjected to corresponding high forces, an upper part of the top unit deforms by being bent backwards in the travel direction of the vehicle so that the at least one vertical beam or tube and the connecting member form a skid-plate against the ground while at the same time only negligibly impairing a space protected by the rollover protection system, wherein the at least one beam or tube has a locally arranged weakened section located in opposing walls at the tapered section.
