Abstract
The invention concerns impact-absorber devices, an impact-absorption method, and a framework and a vehicle including such impact-absorber devices. According to the invention, the impact-absorber device comprises at least one longitudinal member absorbing by deformation the energy generated by an impact in a given direction, which member is made from thin plate, having a generally triangular cross-section in a plane perpendicular to the direction of impact. Applications to rail vehicles, for example.
