Abstract: A clamp mechanism for a steering column assembly includes a support bracket; a clamp pin; a fixing member; and a toothed rack. The toothed rack includes a plurality of recesses each spaced from an adjacent recess by a land and extends alongside the elongate slot. A locking pin is located in a bore in the fixing member that is biased in a direction towards the toothed rack by a spring and a clamp means which may cause the fixing member to move between a clamped condition and unclamped condition.

Abstract: A telescopic steering column assembly comprises a telescopic shroud having an inner shroud portion and an outer shroud portion, and a telescopic steering shaft that passes through the shroud, comprising an inner shaft portion and an outer shaft portion. The telescopic steering shaft is supported by the shroud through a support assembly interposed between the outer shaft portion and the inner shroud portion, which in use, limits or removes free play between the telescopic steering shaft and the shroud that would otherwise occur in at least one direction orthogonal to the telescopic movement.

Abstract: A collapsible steering column assembly comprises a telescopic steering shaft that is supported within a steering column shroud. The telescopic steering shaft comprises a first shaft having a hollow end with an inwardly facing wall and a second shaft that has an end that is located within the hollow end of the first shaft. A damper device is located at the end of the second shaft that is located within the hollow end of the first shaft and includes a contact member defining a contact part that contacts the inwardly facing wall. A portion of the inwardly facing wall tapers away from the open end of the hollow end so that in the event of a collapse of the steering column assembly the damper device is forced to move along the tapered portion whereby it is increasingly deformed radially thereby to provide a resistance to further collapse of the steering column assembly.

Abstract: A clamp mechanism for a steering column assembly comprises a support bracket; a clamp pin that passes through an elongate slot in the support bracket and an opening in a shroud of the steering column; a fixing member; a toothed rack carried by the support bracket in a position facing the fixing member, the toothed rack comprising a plurality of recesses each spaced from an adjacent recess by a land, the toothed rack extending alongside the elongate slot; a locking pin located in a bore in the fixing member that is biased in a direction towards the toothed rack by a spring; and clamp means that in use causes the fixing member to move between a clamped condition and unclamped condition.

Abstract: A shaft having a splined portion comprises a first set of teeth with each tooth spaced radially at intervals about a first outer circumferential region of the shaft and a second set of teeth comprising an equal number of teeth to the first set that are also spaced radially at the same regular intervals about a second outer circumferential region of the shaft that is offset axially from the first region, with at least one tooth of the first set of teeth aligned with a corresponding tooth of the second set to form a pair in which the two teeth of the pair together form an elongate spline; and wherein the first tooth and second tooth of each elongate spline are separated from each other in a direction parallel to the axis of the shaft by a groove that terminates at each end by a shoulder forming an end of a respective tooth, characterised in that each shoulder is tapered in a direction normal to the axis of the shaft and in that an overmolding is provided that comprises a portion that covers the teeth that is co

Abstract: A steering column assembly includes a clamp mechanism comprising a clamp pin that passes through an opening in a shroud of the steering column assembly and an opening in a bracket that supports the shroud of the steering column assembly. A first reaction member is secured to one end of the pin and a second reaction member secured to another end of the clamp pin, the reaction members defining a length of clamp pin between them that passes through the opening in the shroud and the opening in the support bracket. A cam mechanism has a fixed part and a moving part, each having an opening through which they are threaded onto the clamp pin between one of the reaction members and the support bracket.
