Sperrvorrichtung für eine verstellbare Lenksäule.

摘要

A locking device for an adjustable steering column assembly for a vehicle has first and second interengageable disc members (10, 11) each being provided with toothed areas (17, 18) which pass through respective windows (19, 20) of the other disc member to engage in corresponding portions of the steering column. A spring (12) is interposed between the two members to urge them apart which has the effect of withdrawing the toothed profiles out of engagement with the steering column assembly so that they are retracted in the windows. The invention has for its effect to facilitate free movement of a steering column in a fore and aft direction and/or up and down direction, whilst being able to reliably lock the column in position when desired.
