ABSTRACT:
A vehicle steering column is decoupled in the event of a frontal impact of the vehicle to prevent frontal crash forces from reaching the upper steering column. A releasable coupling interconnects upper and lower portions of the steering column and includes a clamping arrangement normally to clamp the two portions together. The clamping arrangement is released upon forcible shifting of the lower portion towards the upper portion.
