The invention concerns a shock absorbing device, particularly between a mobile gear (1) and an obstacle (2) or between two mobile gears consisting of an energy absorbing structure (3) capable of being extended by actuators (4) controlled to operate. Said device is characterised in that the extensible structure (3) is made up of compressible beams (6) which, when the structure (3) is in extended position, absorb by their irreversible axial compression the energy generated by an impact produced along a specific direction (D), said compressible beams (6) being linked to one another and/or to rigid guiding elements (7) by linkages (8, 9, 11) allowing a rotating and/or translating movement of said beams (6) when the structure (3) is being extended.
L'invention concerne un dispositif amortisseur de chocs, en particulier entre un engin mobile (1) et un obstacle (2) ou entre deux engins mobiles du type constitué d'une structure (3) d'absorption d'énergie déployable par l'intermédiaire d'actionneurs (4) commandés en fonctionnement. Ce dispositif est caractérisé en ce que la structure (3) déployable est constituée au moins de poutres (6) compressibles qui, en position déployée de la structure (3), absorbent par leur compression axiale irréversible l'énergie engendrée par un choc se produisant selon une direction (D) donnée, lesdites poutres (6) compressibles étant liées entre elles et/ou à des éléments rigides de guidage (7) par des liaisons (8, 9, 11) autorisant un mouvement de rotation et/ou de translation desdites poutres (6) au cours du déploiement de la structure (3).
