| 20110210536 | ADJUSTABLE STEERING COLUMN FOR MOTOR VEHICLES - An adjustable steering column for a motor vehicle has a support assembly intended to be fixed to a chassis of a vehicle, a tubular body slidably mounted in the support assembly, adjustment and locking devices able to switch from a state of a adjusting the position of the tubular body in the support assembly to a state of immobilizing the tubular body in a desired adjusted position within the support assembly, a plastically deformable energy-absorbing element collaborating with a deformation member secured to the tubular body so that it undergoes plastic deformation as the tubular body retracts inside the support assembly following an impact transmitted to the tubular body when the adjustment and locking devices are in the locked state and a ratchet mechanism for securing the plastically deformable element to the support assembly during plastic deformation of the plastically deformable element. | 09-01-2011 |
| 20110174028 | DEVICE ASSISTING WITH THE LOCKING OF A STEERING COLUMN - A device for the assisted locking and unlocking of an adjustable steering column has a fixed cam element secured to a column body, a moving cam element extended by an operating lever, and an articulation system coupled to a central spindle mounted between the elements and passing through the body. The articulation system includes an elastic return member intended to collaborate with two sets of complementary bosses borne respectively by each cam element and delimiting with one another, two end-of-travel stops so that by pivoting the lever, the moving cam element can be made to move between a locked position and an unlocked position via an intermediate position of unstable equilibrium. | 07-21-2011 |
| 20110121552 | DEVICE FOR ADJUSTING A STEERING COLUMN - 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. | 05-26-2011 |
| 20100170364 | ELECTRIC CLAMPING DEVICE FOR AN ADJUSTABLE MOTOR VEHICLE STEERING COLUMN - 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. | 07-08-2010 |
