20090199673 | WEDGE ARM POSITIVE RAKE LOCK - A steering column assembly includes a column jacket coupled to a mounting bracket, with the column jacket pivotably movable about a pivot axis relative to the mounting bracket. A wedge arm is pivotably mounted to one of the column jacket and the mounting bracket and wedges against the other of the column jacket and the mounting bracket. The wedge arm prohibits the pivotable movement of the column jacket relative to the mounting bracket in response to an impact event. The wedge arm includes an arcuate shape having a variable radial distance between a pivot attachment point and a contact edge. The variable radial distance permits the wedge arm to fit between components of the column jacket and the mounting bracket when the column jacket is positioned in different positions relative to the mounting bracket. | 08-13-2009 |
20110006509 | Steering Column Assembly Comprising A Mounting Capsule - The instant invention includes a mounting capsule for a steering column assembly of a vehicle. The mounting capsule has a first capsule portion and a second capsule portion coupled together during normal operation. The first capsule portion includes a first arm and a second arm each having a first taper and a second taper. The second capsule portion includes a first groove and a second groove tapered in a complimentary configuration to the first and second arm for receiving the first and second arm. Frictional forces between the first and second capsule portions aid in coupling the first and second capsule portions and effectively reduce lateral and vertical movement in a steering column assembly during operation. Upon an impact event exerting a predetermined impact force the first and second capsule portions disengage allowing the steering column assembly to collapse. | 01-13-2011 |

An axis of rotation is offset from the center axis of the stepped gear, and is configured to create a variable gear ratio between the set of teeth of the inner step or the outer step of the stepped gear and the array of rack teeth as the rack is moved in a linear direction. | 05-09-2013 |
20130160594 | Telescoping Jacket Interface Mechanism - A steering column assembly is provided, and includes an inner jacket, an outer jacket, and a bracket. The inner jacket has an inner jacket outer surface. The outer jacket has an outer jacket outer surface. The inner jacket is slideably disposed in the outer jacket for telescoping movement relative to the outer jacket. The outer jacket has at least one aperture for exposing the inner jacket outer surface. The bracket has at least one inner jacket riser and at least one outer jacket riser. The inner jacket riser is positioned to be received by the at least one aperture and selectively frictionally engage with the inner jacket outer surface. The outer jacket riser is positioned to selectively frictionally engage with the outer jacket outer surface. | 06-27-2013 |
