ABSTRACT:
Apparatus is provided for adjustable mounting a steering column in a vehicle, whereby the column may be telescoped, tilted or both, simultaneously, by unlocking the mechanism with a single handle. The mechanism includes a pair of side frames fixed within the vehicle, and an inner tube fixed to the column and movable between the side frames. When the handle is turned to lock the mechanism, the clamping portion of the mechanism draws the slide adjusters toward the inner tube, forcing the generally heart-shaped slides toward the inner tube and biasing them away from the longitudinal axis of the mechanism. This movement of the slides forces the pin connecting each opposite pair of slides into engagement with both the front frictional surface of the inner tube and with the outer surface of the slot within which the particular pin travels, thereby trapping and frictionally holding the inner tube relative to the side frames. The mechanism takes advantage of the ability of friction type devices to be infinitely adjustable, while utilizing the frictional engagement in a manner which provides a more positive type of locking, resulting in a higher holding torque.
