active energy absorbing device for a motor vehicle and motor vehicle equipped with the same.

摘要

Device for absorbing energy (12; 12 ') for a motor vehicle, comprising: - a transverse beam (14) of absorption of high energy shocks, intended to be fixed to a chassis (2) of the vehicle by fixing a rear face (21) of the beam about right (4) left chassis crossbars (6) and; and - a structure (16, 16 ') of shock absorption reduced power, fixed to a front face (25) of the transverse beam, characterized in that it further comprises: - at least two deformable elements energy absorption (18, 20) housed between the frame and the front face of the beam and intended to be located at the level of each of the chassis members, each deformable element energy absorbing a first stiffness in a first direction (D1) and a second rigidity, different from the first stiffness, along a second direction (D2); and - a drive means (40, 42, 44, 46, 48; 60, 62, 64, 66) able to orientate said deformable elements absorbing energy to align the first direction or the second direction with a reference axis (X), said absorption device active energy.
