Abstract
A steering column assembly comprises: a housing having outer, intermediate and inner elongate, telescopically mounted housing portions movable relative to one another along an adjustment axis; a steering column rotatably mounted in the inner elongate housing portion and being configured at one end for attachment of a steering member (e.g. a steering wheel); a leadscrew rotatably mounted on one of the inner and outer housing portions and having first and second threaded portions which overlap each other for at least part of the length of the leadscrew; a motor for rotating the leadscrew; a first displacement member screw-threadedly mounted to the first threaded portion of the leadscrew and connected to the outer or inner elongate housing portion on which the leadscrew is not rotatably mounted; and a second displacement member screw-threadedly mounted to the second threaded portion of the leadscrew and connected to the intermediate housing portion. Rotation of the leadscrew causes displacement of the first and second displacement members along the adjustment axis.
