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: According to the disclosure, the steering column comprises a steering shaft rotatingly mounted in a tube-body provided on a side mount of a fixed bearing assembly via a lateral mechanism. The column can be adjusted in height and/or depth by an axis clamping system with a clamping rod (interacting with the lateral mechanism. The lateral mechanism comprises a bearing member provided between the side mount and a side member of the tube-body. A cross-section arranged between the bearing member and the side member enables counter-rotation. The lateral mechanism includes a system for adjusting the sliding clearance on the clamping rod using a bearing member and an adjustable clamping head.

Abstract: Device for coupling an inner shaft and an outer shaft which slide along their common axis with balls positioned between the two shafts. The balls rest directly in axial grooves of the outer shaft and on two rails positioned in axial grooves of the inner shaft. The two rails pivot about the balls, by pressing against flanks of mating curved profile of the axial groove, and are held in place by an elastic element which presses against the bottom of the axial groove.

Abstract: A device for coupling an inner shaft and an outer shaft includes balls arranged in rows between axial grooves of the inner shaft and axial grooves of the outer shaft, enabling the shafts to slide in the direction of a common axis. Each row of balls is maintained by a double elastic member that bears in the groove of one of the inner or outer shafts and urges the balls along two rolling tracks so that they come into contact with the groove of the other of the inner and outer shafts. The two rolling tracks are hinged through a convex pivot surface and a corresponding concave support face of one of the inner and outer shafts, and a difference between the radii of the pivot surface and the support face defines two contact areas and a pivot axis parallel to the common axis.

Abstract: In an adjustable steering column adjustable, a steering shaft is mounted in a body tube arranged in an intermediate carrier mounted on a fixed support member. The body tube is immobilized onto the fixed support member by a clamping system. The position-keeping device includes teeth that, in the event of an impact, are mutually engageable by means of a press system mounted in the intermediate carrier and under the action of the clamping system. The teeth belong to of the press system and are on the body tube. The teeth have characteristics defined such that in the event of an impact, the breaking force of the teeth has a predetermined value.

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.

Abstract: The yoke member of Cardan joint is made in one unitary part of one piece and includes a pivot fork including two pivot arm portions each comprising a crossing hole, the axis of which is the pivot axis of a cross-piece, and a connecting element for the motion transmission shaft and having two tightening portions connected via a junction portion. Each of the two tightening portions comprises a tightening hole. Four reinforcing appendices are arranged on the tightening portions and opposite one another in pairs to form together with the portions a housing for the motion transmission shaft. The yoke member is stamped in order to give it the desired thickness in highly stressed and lowly stressed regions.

Abstract: A motorized steering column module with position control including a moving device that moves a steering wheel in an axial direction, bringing it closer or further away from a selected position, and in a radial plane for regulating upward and downward movement with the aid of at least one electronic motor controller; and a controller that varies the speed of the motor at least proximate a departure position and an arrival position.

Abstract: Device for coupling an inner shaft and an outer shaft that slide in the direction of a common axis with balls disposed between the two shafts. The balls are disposed in axial grooves of the inner shaft and in axial grooves of the outer shaft. Each row of balls is held by a double spring member that bears on the groove and which pushes on two rolling tracks for the balls, which come into contact with the groove. The two rolling tracks are articulated at the junction of the groove and the inner shaft.
