Abstract: A steering column including an upper body, two connection flanges for connecting the upper body to a support element, and a tightening and blocking device the upper body in position on an internal tube, where the tightening and blocking device includes a clamp screw extending through the flanges, a set of cams comprising a fixed cam and a movable cam mounted such that it can move freely in translation along the clamp screw and arranged so that it can bear on one of the flanges, a rack capable of cooperating with a notched arrangement provided on the other flange, and a resilient means arranged between the movable cam and the rack in order to exert a return force on the rack in the direction of the notched flange.

Abstract: This invention relates to a device for fastening comprising a jaw, a screw with a diameter d and a shaft, the jaw having two parallel flanks surrounding a portion of the shaft, with the shaft having a peripheral recess in line with the screw in assembled position and with each of the flanks having an orifice that the screw passes through, it is characterised in that one of the orifices is of oblong shape. The oblong shape of the orifice makes it possible to prevent the screw from becoming “stuck” between the shaft and the orifice when the shaft is incorrectly positioned, by releasing the screw as soon as the latter enters into interference with another part or an obstacle and as such makes it possible to prevent the transmission of a torque between the two parts to be attached.

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.
