The invention relates to an electric locking system () 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 () for locking the tube-body on the supporting assembly, an electric motor () coupled to the locking means () 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.

System for electrically locking a steering column, and steering column including such a locking system

A device for adjusting a steering column includes a body and a cap assembled by a pivot and a connection element enabling the displacement of the body with respect to the cap under the action of a motor-reduction unit mounted on the body. The device is characterized in that the connection element includes at least one arm of which a first end is attached to the cap and a second end is connected to a threaded rod with vertical displacement cooperating in rotation with the drive shaft of a motor-reduction unit so that the arm forms a hinge enabling the reversible angular displacement of the body with respect to the cap.
