Abstract: The invention relates to an electric locking system (1) for locking the position of a steering column of a vehicle relative to the dashboard of said vehicle, the steering column including a tube-body movably mounted in a supporting assembly for enabling the manual adjustment of said steering column. The locking system includes means (2) for locking the tube-body on the supporting assembly, an electric motor (4) coupled to the locking means (2) for driving the latter and placing the steering column in an unlocked state or a locked state, motor control means providing motor actuation instructions for placing the steering column in the locked state and/or in the unlocked state, and means for detecting the state of the steering column and for generating an electric signal representative of the state of the column.

Abstract: An adjustable steering column adjustable includes a steering shaft mounted in a body tube arranged in a movable support member and immobilized on a fixed support member by an electric clamping system. The clamping system is mounted in a casing supporting an electric actuator and includes a transmission mechanism, an immobilizing assembly and a clamping rod passing through the fixed support member. The immobilizing assembly includes a fixed cam rotationally fixed with respect to the clamping rod, and a rotationally movable cam, the cams having rolling paths for balls. Each rolling path has the shape of a spiral with an escape slope for a ball, in order to initiate clamping or unclamping depending on the rotation direction of the movable cam relative to the fixed cam.
