Abstract
An absorber of steering column shock energy includes a plastically deformable part forming a loop, a breakaway link closing this loop on itself, and a first attachment interface and a second attachment interface separate from the breakaway link and arranged on either side of the loop. The part and the fusible link are arranged so that the exertion of forces in opposite directions on the first attachment interface and on the second attachment interface respectively, causes a stress leading to a deformation of the loop, breaking of the breakaway link and further deformation of the loop after this break.
