Abstract: A lock for an adjustable steering column includes a rotatable locking lever to actuate the lock between an unlocked position and locked position, a lock plate including plate lock teeth and a first slot, and a slider including slider lock teeth and a second slot angled relative to the first slot. The slider teeth are received between respective plate lock teeth. A lock bolt rotates with the locking lever and extends through the first and second slots, and has a retainer on one end. A cam positioned on the lock bolt applies or releases a force to the slider in response to rotation of the locking lever to actuate the lock. In the locked position the slider lock teeth lockingly engage between the plate lock teeth, and in the unlocked position, the slider lock teeth are released from locking engagement with and are positioned between the plate lock teeth.

Abstract: A steering column assembly has a mount bracket configured for attachment to a fixed vehicle support member in a releasably fixed position and for release from the fixed vehicle support member to a released position during a steering column energy absorbing event. A steering jacket is operably supported by the mount bracket. The steering jacket has at least one interface feature arranged to confront the mount bracket during the steering column energy absorbing event to inhibit rotational movement of the mount bracket relative to the steering jacket when the mount bracket moves from the fixed position to the released position.

Abstract: An axially adjustable steering column includes a first jacket. The steering column also includes a second jacket, wherein the first jacket is axially adjustable relative to the second jacket. The steering column further includes an adjustment lever. The steering column yet further includes a locking mechanism, wherein the adjustment lever selectively moves the locking mechanism between a locked position and an unlocked position, wherein the locked position prevents axial adjustment of the first jacket relative to the second jacket in both axial directions, and the unlocked position allows adjustment of the first jacket relative to the second jacket.

Abstract: A locking mechanism for an axially adjustable steering column includes a lock cam including a cam portion and a hub portion, wherein the cam portion and the hub portion are independent, separately formed components. The locking mechanism also includes a pin extending through the cam portion to permit the cam portion to pivot. The locking mechanism further includes a toothed portion formed on the cam portion for pivoting into engagement with teeth associated with the axially adjustable steering column in a locked position and out of engagement with the teeth in an unlocked position. The locking mechanism yet further includes an interface surface on the hub portion that includes at least one angled surface that interfaces with an adjustable lever and biases the cam portion from the locked position to the unlocked position.
