Patent ID: 8388259

Claim:
A mechanism for absorbing kinetic energy in shock absorbers and barrier ends for roadways, comprising; a deformable metallic profile ( 2 ) of open section in the form of a “U”, “C”, “Σ” or “Ω”, being directly or indirectly secured to the ground ( 4 ), a ram ( 1 ), being attached directly or indirectly to a structural element which is capable of being displaced longitudinally, as a consequence of an impact of a vehicle ( 5 ), the ram ( 1 ) having a partial or total intersection with a transversal section of the deformable metallic profile ( 2 ), and capable of producing thereto plastic deformations which are propagated along the deformable metallic profile ( 2 ), as the ram ( 1 ) is longitudinally displaced along said deformable metallic profile ( 2 ).
