The invention concerns a device for clamping a system adjusting the position of a member () relative to a support assembly (). The adjustment system can adjust in height and/or in depth an automobile vehicle steering column body-tube considered as the member. The member is disposed inside two vertical uprights () of the support assembly. The clamping axis () is perpendicular to the two uprights. The device comprises a bracket () consisting of a base () and two tie-rods () which are connected by a closure and support member () on one () of the uprights, and an external clamping rod () mounted on the base. A locking assembly (), an intermediate member bearing on the upright () and disposed between the base () and the locking assembly (), and an axial retention assembly () for the locking assembly that is adjusted to obtain clamped and unclamped positions, are mounted on the external clamping rod ().

Device for clamping a member adjustable relative to a support assembly

A system for variable absorption of energy in the direction of the axis of an automobile vehicle steering column includes a steering shaft mounted in a body-tube connected to a mobile support member connected to a fixed support member fastened to the chassis of the vehicle and immobilized thereon up to a particular value. A coil is disposed on each side of the steering shaft and is connected to each of the fixed and mobile support members by a respective connecting pin A pyrotechnic displacement system operates selectively on a mobile retaining rod of each coil to modulate the absorption of energy in the event of an impact.
