Abstract: A device for preventing rotation of the steering column body of an automobile vehicle comprising a support member attached to the chassis of the vehicle and a body which is held in position relative to the support member by a locking system. For the adjustment of the steering column concerned in the required direction at least one pair of coupling surfaces is joined to the support member and cooperate with a pair of coupling surfaces joined to the body. The coupling surfaces have a direction substantially parallel to the required adjustment direction and are angularly oriented with respect to major faces of the support member and the body, so that the coupling surfaces cooperate with each other upon locking in order to prevent rotation of the steering column body.

Abstract: In an automobile vehicle steering column including a steering shaft mounted in a tube-body by means of bearings and attached to a reinforcing member of the tube-body which is mounted on a support member fixed to the chassis of the vehicle and an adjustment system with an axle for locking the support member, an active retraction device in the steering column comprises two sloping wedges mounted on and having conjugate inclinations relative to the axle, and at least one fusible pin coupling the sloping wedges. The inside sloping wedge is disposed around the depthwise adjustment slide and the outside sloping wedge is attached to the axle of the adjustment system. In the event of an impact, the fusible pin is sheared by the triggering of an air-bag and allows the sloping wedges to move apart and to release the tension in the adjustment system axle in order to allow the steering shaft to move in a required direction.

Abstract: A steering column includes a steering shaft freely rotatable in a tube-body disposed in a support member attached to a chassis of the vehicle. The tube-body is locked by a system for adjusting its position. The positioning device comprises an additional guide system for the tube-body in the event of an impact such that the angle of the steering shaft and the steering wheel of the vehicle to the horizontal plane is smaller after retraction of the steering wheel in order to allow correct functioning of the air-bag.

Abstract: An energy-absorbing device disposed between two elements which are movable apart from each other in response to an externally applied force.

The body-tube and steering shaft are received in the support structure and clamped and locked therein by clamping elements coactive with the support structure. A locking device is provided with a rotatable elongate locking element to which is connected an operator for rotating the axis of the locking element in a direction for clamping the body-tube between coacting clamping elements and vertical sides of the support structure. The locking element is a bolt or rod having reverse pitch nuts on opposite ends and which tighten the sides of the support structure and clamping elements toward the body-tube to lock the body-tube in place when the locking element axis is rotated by the locking device operator.
