Abstract
A collapsible steering column assembly includes: a mounting bracket having a pair of arms and is configured to be fixed to a vehicle body; a supporting housing which is disposed between the pair of arms to be tiltable about the mounting bracket; a steering column which passes through the supporting housing so as to be able to undergo a tilt motion together with the supporting housing; and a locking device which is configured to be in a locking state or an unlocking state to selectively allow a telescopic motion and a tilt motion of the steering column by selectively applying clamping force to the pair of arms. The steering column comprises an outer jacket, an inner jacket which is slidably inserted into the outer jacket and a tolerance ring which is interposed between the outer jacket and the inner jacket, and the tolerance ring is configured so as to make the inner jacket and the outer jacket move together to realize a telescopic motion in the unlocking state of the locking device and so as to allow the inner jacket to move into the outer jacket by impact in the locking state of the locking device. The tolerance ring is configured to move relative to the outer jacket in a longitud…
