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.

The steering column having a lug, a casing, an inner tube, an outer tube, a steering wheel end-piece, and at least one adjustment gear motor. The lug is axially movable and the column includes a gear motor controlling the lug. Having a movable lug makes it possible to increase the stowing length of the steering wheel. The range of movement is the sum of the movements of the lug and the adjustment gear motor.

Device for stowing a steering column

A steering column including an upper body, two connection flanges for connecting the upper body to a support element, and a tightening and blocking device the upper body in position on an internal tube, where the tightening and blocking device includes a clamp screw extending through the flanges, a set of cams comprising a fixed cam and a movable cam mounted such that it can move freely in translation along the clamp screw and arranged so that it can bear on one of the flanges, a rack capable of cooperating with a notched arrangement provided on the other flange, and a resilient means arranged between the movable cam and the rack in order to exert a return force on the rack in the direction of the notched flange.
