Telescopically adjustable steering column assembly including an adjustment stop having minimal effect on impact loads

摘要

A steering column assembly includes a column jacket adjustable along a longitudinal axis and collapsible along the longitudinal axis in response to a collision event. A compression bracket is mounted to the column jacket and defines a telescope slot having an adjustment portion and a continuation portion. A shaft extends through the telescope slot with the column jacket and the compression bracket moveable relative to the shaft during adjustment and collapse of the steering column assembly. A stop is detachably coupled to the compression bracket and partially covers the telescope slot to prevent movement of the shaft into the continuation portion during adjustment. The stop detaches during collapse to permit the shaft into the continuation portion. A lever rotates with the shaft and includes a tab for engaging the stop when the lever is in an unlocked position to prevent detachment of the stop during adjustment.
