Steering column including a rotational blocking device actuated by a motorization

A steering column for a motor vehicle including two telescopic drive shafts linked in rotation, allowing an axial sliding of a front shaft of the telescopic drive shafts supporting a steering wheel, successively over, starting from the most forward position, a first range of depth adjustment of the position of the steering wheel, then a second damping range used in the case of an accident for damping an impact of the driver on the steering wheel, the column including an electric motorization for controlling the sliding, and an anti-theft blocking device to be engaged, when engaged the anti-theft blocking device being able to block the rotation of one of the telescopic drive shafts, wherein when the rotational blocking device is engaged for blocking the front shaft, the front shaft is placed at an axial position given by the motorization, the axial position being located in the second damping range.
