Abstract: Technical solutions are described for a clamp mechanism of an adjustable steering column assembly. The clamp mechanism comprises a fixed bracket configured for rigid attachment to a vehicle, and a movable bracket configured to hold a steering shaft. An adjustment nut threadedly engages an adjustment bolt, the adjustment nut or the adjustment bolt moves between an adjustment position and a holding position, selectively coupling the movable bracket to the fixed bracket in the holding position. The fixed bracket defines a first slotted aperture to guide the adjustment bolt in a linear path for adjusting a position of the steering shaft. A positive locking member moves to a locked position, blocking the adjustment bolt from moving along the first slotted aperture in a crash event. A friction plate is pivotably coupled to the fixed bracket to pivot as the positive locking member moves between an unlocked position and the locked position.

Abstract: A rake adjustment assembly for a steering column system includes a rake lever that is rotatable. The rake adjustment assembly also includes a rake bolt operative coupled to the rake lever and positioned to selectively exert a clamping force to lock and unlock the rake position of the steering column system. The rake adjustment assembly further includes a cam assembly comprising an outer cam formed of stamped steel and press fit within a pocket defined by an outer face of the lever. The outer cam includes a main body. The outer cam also includes a plurality of legs extending from the main body.
