Abstract
An adjustable steering column assembly includes a first shroud portion comprising an outer tube, a second shroud portion which comprises an inner tube, and a clamp mechanism that includes a part that is fixed relative to the outer tube, the first and second shroud portions being releasably engaged by the clamp mechanism to selectively permit an amount of relative movement between the first and second shroud portions that is required during adjustment of the steering column assembly, the assembly further including an energy absorbing member which includes a strap that interconnects the inner tube and the part of the clamp bolt assembly, the assembly being so arranged that upon collapse the inner tube moves relative to the clamp assembly whereupon the energy absorbing member is deformed beyond its elastic limit, thereby absorbing energy in the system to control the collapse of the assembly.
