Abstract
An adjustable steering column for a motor vehicle has a support assembly intended to be fixed to a chassis of a vehicle, a tubular body slidably mounted in the support assembly, adjustment and locking devices able to switch from a state of a adjusting the position of the tubular body in the support assembly to a state of immobilizing the tubular body in a desired adjusted position within the support assembly, a plastically deformable energy-absorbing element collaborating with a deformation member secured to the tubular body so that it undergoes plastic deformation as the tubular body retracts inside the support assembly following an impact transmitted to the tubular body when the adjustment and locking devices are in the locked state and a ratchet mechanism for securing the plastically deformable element to the support assembly during plastic deformation of the plastically deformable element.
