Abstract: A steering column assembly comprises a first support bracket, a second support bracket, a shroud, and an energy absorbing device. The energy absorbing device comprises a laminated strap having discrete first and second layers, each formed from a separate elongate strip of material that is free to slide over the other strip along a major portion of its length, a portion of the laminated strap being coiled into a spiral, a free end portion of the laminated strap passing through passing through an opening in the second support bracket or the shroud, the free end of a first one of the strips having an opening through which a fastener passes that secures the laminated strap to the first support bracket, and the free end of a second one of the straps being connected to the first strip in a region distal from the free end of the first strip.

Abstract: A locking lever for a clamp mechanism of a steering column assembly comprises a first portion, a second portion that extends from the first portion, and a connecting portion or region located between the first portion to the second portion about which the second portion will preferentially breakaway from the first portion in the event of an impact by an occupant of the vehicle on the second part, the lever further comprising a flexible tether that prevents the second portion fully separating from the first portion after the lever has broken about the connection portion or region.

Abstract: A steering column assembly comprising an inner tube and an outer tube that surrounds the inner tube along at least part of its length, in a relaxed condition the outer tube being a relatively loose fit around the inner tube, an elongate slot in the outer tube which can be at least partially closed by applying a load either side of the slot to cause a reduction in the internal diameter of the tube, the slot extending along the outer tube starting from one end of the tube, a pair of flanges which are fixed to the tube on opposing sides of the slot, and a clamp mechanism which connects one flange to the other, the clamp mechanism being movable between a clamped position in which it applies a clamping force to the flanges that acts to reduce the width of the slot and so tightens the outer tube around the inner tube, and an unclamped position in which the clamping force is reduced to permit the flanges to move away from one another as the tube returns towards its relaxed condition.
