Motor vehicle e.g. commercial vehicle, structural assembly, has crosspiece articulated on posts via hinges that are released such that crosspiece passes from one position to another by pivoting around hinge opposite to released hinge

摘要

The assembly has a structural crosspiece (211) mounted between two rear posts (10A, 10b) so as to be selectively placed in an operating position in which the crosspiece ensures rigidifying function to a vehicle and for supporting a load in the vehicle, and a retracted inactive position. The crosspiece is articulated on the posts through respective hinges, which are released selectively such that the crosspiece passes from one position to another by pivoting around the hinge opposite to the released hinge.
