An X-axis steering column includes a cap, a U-shaped tab attached to the cap, and an upper tube that slides relative to a lower tube. An attachment for attaching the cap to the U-shaped tab includes two screws and at least one stop in contact with at least one lateral groove. The at least one stop is configured to absorb lateral loads without any longitudinal movement of the steering column being impeded, including during adjustment of the steering column or during an impact due to a collision.

Stop for absorbing lateral loads

The present invention relates to a meshing plate () of a steering column energy absorbing device, comprising a base plate () formed of a first material and comprising a row of first meshing shapes () extending along a longitudinal axis (A); the meshing plate comprises lateral protrusions () overmoulded onto said base plate so that each comprises a rear abutment surface () and/or a lateral bearing surface ().

Steering column energy absorbing device meshing plate

Steering column comprising a cradle () mounted tilting on the body of the vehicle and receiving, in a deformable bearing (), a sleeve () provided with a tube bearing the steering wheel. A clamping device () comprising a manoeuvring lever () bearing a clamping axle () and pressed against a bearing block () by a ramp connection () and by an escutcheon () with teeth (). The bearing block (), has a ramp () for each tooth () ending in a stop () projecting into the circular segments () between two teeth (). One of the teeth () has, on its unclamping side, a damping element ().

Steering column

A steering column having an adjustment limit stop device comprising a body receiving, in a deformable bearing, the sleeve carrying the steering wheel and a mechanism for clamping a shaft with a lever carrying a clamping device compressing the deformable bearing. The steering column comprises a stop device provided with a stop edge carried by the sleeve and with which a lock cooperates that limits the adjustment travel of the sleeve while being retracted after the adjustments of the column have been clamped, allowing the sleeve to travel, in the event of an impact on the steering wheel, in order to absorb the energy.

The present invention relates to a modular energy absorption device () comprising:

Modular energy-absorbing device

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.

Energy absorption position-keeping device in an automotive vehicle steering column

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.
