Abstract

An energy absorption device for a steering column for a vehicle includes a resilient device, preferably in the form of a coil spring, having turns that are wound in a clamping manner around a component such as a cylindrical rod connectable to the steering column. The coil spring and cylindrical rod are slidable relatively to each other to absorb energy in the event of a vehicle crash. An adjusting device is arranged to vary the clamping force of the turns of the coil spring on the rod by winding or unwinding the coils of the spring. The clamping force may be adjusted in accordance with data such as stature of the driver, vehicle speed and vehicle attitude.
