  • Impact-absorber devices, impact-absorption method, and framework and vehicle including such impact-absorber devices
    Patent number: 5715757
    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.

  • Device for facilitating access to a rail vehicle having extendable ramp assembly
    Patent number: 5357869
    Abstract: Access to a rail vehicle is effected by a board that is movable between a retracted position in which it is housed beneath the top face of the floor of the vehicle and an extended position in which it constitutes an access ramp between a platform and an entrance doorsill of the vehicle. The device includes an actuator for driving the board and a stop terminating translation of the board in its extended position. The actuator is disposed in the plane of the board. The device also tilts the board after stopping the board's movement in translation so that the outside end of the board rests on the platform and so that the board co-operates with the entrance doorsill to provide a continuous surface without any offset. The entrance doorsill remains stationary.
