Abstract
A steering column assembly for a vehicle comprises a motorized length adjustment drive unit, a box rocker having a control surface, a column jacket, and a crash bracket releasably coupled to the column jacket. The assembly includes an energy absorbing member having a proximal end and a distal end. The proximal end is coupled to the crash bracket and the distal end is coupled to the column jacket. A plate is attached to the box rocker such that a channel is formed between the plate and the control surface. At least one anti-rotation member is coupled to the crash bracket and extends through the channel. The at least one anti-rotation member is adapted to inhibit rotation of the crash bracket during a frontal collision of the vehicle.
