Telescopic shaft for a steering column

摘要

A telescopic shaft for use in a motor vehicle steering column comprises at least two tubular telescoping sections 1, 2 formed with complementary longitudinal ribs and grooves 6, 7 and at least one projection 10, 10 formed on one of the sections to engage the end of at least one rib when the shaft is telescopically shortened to a predetermined minimum length so that further axial shortening may only be achieved by the deformation of the rib(s) in contact with the projection.
