An adjustable steering column assembly has a steering shaft 18 to which a steering member is attachable at one end 20, an elongate housing 16 within which shaft 18 is rotatably mounted about its longitudinal axis X; a base 12 in which housing 16 slides and with respect to which the steering shaft housing is slidably mounted and constrained to move along axis X for reach adjustment; and a support bracket 22 attachable to a vehicle. Base member 12 is displaceably mounted with respect to support bracket 22 in a rake adjustment direction. The assembly also has first and second securing mechanisms (46, Figure 9) for controlling displacement of housing 16, each having a rack member (50, Figure 9) with an elongate slot, first and second racks of teeth (58, 60, Figure 9) on opposite sides of the slot and a pivotally mounted lock member 66 with two rows of teeth (62, 64, Figure 9) complementarily shaped with corresponding teeth the rack member.
