ABSTRACT:
An automotive vehicle steering column assembly includes an elongated collapsible steering column, a lower support for the lower end portion of the steering column and an upper support for the upper end portion of the steering column. The lower support comprises a bracket connected to vehicle support structure and constructed to absorb energy and guide movement of the lower end portion of the steering column when the steering column collapses in a frontal impact. The upper support comprises a swing unit for controlling the movement of the upper end portion of the steering column when it collapses. The swing unit comprises a lock mechanism including a rod slidable in a tubular housing. The rod is connected to the upper end portion of the steering column and can be locked in adjusted position within the housing depending on the tilt desired. A swing arm has one end portion rotatably received in a fixed mounting block, to which the housing of the lock mechanism is connected. A torque bar in the block has a non-rotatable connection to the first end of the swing arm to resist rotation thereof.
