A steering column assembly comprises an adjustable shroud and a locking mechanism that comprises a clamp pin, a locking handle and a cam mechanism fitted to the clamp pin, in which the cam mechanism comprises first and second cam portions which can be moved relative to each other by operation of the locking handle to vary the overall length of the cam mechanism, the unlocked position of the cam mechanism being defined by contact of a first end stop of the first cam portion with a second end stop of the second cam portion. At least one of the end stops comprises a resilient cushioning member which provides cushioning as the at least one end stop engages the other end stop upon the locking mechanism reaching the unlocked position. The resilient cushioning member is free to move so that on a first engagement, a portion of the resilient cushioning member makes contact with the end stop; and on a second engagement, a different portion of the resilient cushioning member makes contact with the end stop. |

1. A steering column assembly comprising an adjustable shroud which at least partially surrounds a steering shaft and a locking mechanism operable between a locked position in which the adjustable shroud part is locked in position and an unlocked position in which the adjustable shroud part can be moved to set the reach and/or rake of the steering column assembly, in which the locking mechanism comprises a clamp pin, a locking handle and a cam mechanism fitted to the clamp pin, in which the cam mechanism comprises first and second cam portions which can be moved relative to each other by operation of the locking handle to vary the overall length of the cam mechanism, the unlocked position of the cam mechanism being defined by contact of a first end stop of the first cam portion with a second end stop of the second cam portion, wherein at least one of the end stops comprises a resilient cushioning member which provides cushioning as the at least one of the end stop engages the other end stop upon the locking mechanism reaching the unlocked position,
wherein the resilient cushioning member is free to move; wherein on a first engagement, a portion of the resilient cushioning member makes contact with the end stop; and on a second engagement, a different portion of the resilient cushioning member makes contact with the end stop. |
