ABSTRACT:
An adjustable steering column for a vehicle having a steering column including adjustment and clamping mechanism, for example a clampable mechanism to allow for reach adjustment of the steering column and for clamping the column at a desired reach position. An energy absorption mechanism is provided to absorb energy upon collapse of the steering column in a crash situation, there being a resilient-loaded pawl and ratchet mechanism associated with the adjustment and clamping mechanism, acting as a primary means in the crash situation to transfer energy from the column to the energy absorption mechanism. A handle acts both to clamp and unclamp the adjustment and clamping mechanism and to bring the pawl and ratchet mechanism into and out of engagement.
