Abstract
A steering column assembly comprises a support bracket, a telescopic shroud having an outer shroud portion and an inner shroud portion, an energy absorbing mechanism that includes a puller, a clamp rail fixed to the inner shroud portion including a slot that extends axially along the inner shroud portion, the slot defining two opposing walls which each carry a row of teeth, the two rows thereby being spaced apart from one another with the teeth extending towards each other; the puller being positioned adjacent the slot, a clamp bolt that extends perpendicular to the shroud, and a toothed block having a row of teeth on each side, the pitch between teeth of each row being equal to, or a whole multiple of, the pitch of the teeth of the corresponding row of the slot. The block is supported by a carrier element that moves in response to rotation of the clamp bolt to move, in turn, the toothed block between a clamped position. A contact face of the puller and a contact face of the toothed block are arranged such that the toothed block is prevented from rotating more than a predetermined amount when forced onto the puller, urging the toothed block into engagement with the teeth of the slot.
