Abstract: A device for protecting a vehicle against impact, the device comprising an inflatable element which, once inflated, presents a general shape that fits closely over the region of the vehicle to be protected, wherein said inflatable element includes a skin which is deployed by an inflatable reinforcement having a volume that is much smaller than the volume of the skin, pressurizing and deploying said inflatable reinforcement ensuring rapid deployment of said skin and simultaneously causing the internal volume of the inflatable element to be filled with air, by suction, via an air inlet device carried by said skin.

Abstract: An energy absorber device for use in vehicles, in particular railroad vehicles, is of generally parallelepipedal shape and can be inserted between a driver's cab and a coach-body. The larger opposite faces of the parallelepiped are disposed in a plane formed by the rear face of the driver's cab and in a plane formed by the front face of the coach-body, respectively.
