<p>A vehicle steering column includes a coupling (20) between two portions (16,18) of the steering column. The coupling (20) incorporates two relatively slidable coupling parts (26,28), a sliding member (50) in contact with one of the two coupling parts (26,28) and a resilient member (24) disposed between said sliding member (50) and the other of the two coupling parts (26,28). The resilient member (24) inhibits transmission of vibration through the steering column and it is stressed or compressed to provide a resilient bias to establish firm engagement of the sliding member (50) with the one of two coupling parts (26,28), thus resisting relative axial movement of the two portions (16,18) of the steering column toward one another. Owing to the provision of the sliding member (24), smooth telescopic movement of the two portions (16,18) of the steering column is provided when a force tending to move the two portions (16,18) of the steering column toward one another exceeds a predetermined value. <IMAGE></p> |
