Abstract:
An axially adjustable steering column assembly includes an upper jacket. And a lower jacket. The steering column assembly further includes a column mounting bracket, wherein the lower jacket is operatively coupled to the column mounting bracket and translates relative to the column mounting bracket, wherein the column mounting bracket defines a first set of tapered rail slots, each of the first set of tapered rail slots disposed on opposite sides of the column mounting bracket and extending longitudinally along the column mounting bracket, wherein the lower jacket defines a second set of tapered rail slots, each of the second set of tapered rail slots disposed on opposite sides of the lower jacket and extending longitudinally along the lower jacket. The steering column assembly yet further includes a first pair of sliding wedge bushings disposed within the first set of tapered rail slots.
Abstract:
A steering column has a tubular jacket supported by a mount bracket. The tubular jacket extends along a central axis between lower and upper ends, and is pivotal about a pivot axis. The mount bracket has first and second sidewalls spaced from one another for movement of the tubular jacket therebetween. The first and second sidewalls have first and second lock features, respectively. A lock bolt extends along a lock bolt axis transversely to the central axis. First and second lock cams are operably supported by the lock bolt for rotation about the lock bolt axis between locked and unlocked states. The first and second lock cams have respective first and second lock cam lock features for engagement with the first and second lock features, respectively, to releasably lock the tubular jacket against pivotal movement about the pivot axis in opposite first and second directions, respectively.
Abstract:
An axially adjustable steering column assembly includes an upper jacket. The steering column assembly also includes a lower jacket, wherein the upper jacket is received within the lower jacket and is telecopingly adjustable therein. The steering column assembly further includes a column mounting bracket, wherein the lower jacket is operatively coupled to the column mounting bracket and translates relative to the column mounting bracket. The steering column assembly yet further includes a first actuator operatively coupled to the upper jacket to control telescoping adjustment of the upper jacket relative to the lower jacket. The steering column assembly also includes a second actuator operatively coupled to the lower jacket to control translating adjustment of the lower jacket relative to the column mounting bracket.
Abstract:
A bushing assembly for a steering column having a fixed jacket and a telescope jacket is provided having a set screw configured for insertion into the fixed jacket, and a radial telescope bushing co-acting with the set screw and having a post and a curved bushing portion configured to pre-load the radial telescope bushing against the telescope jacket to provide a lash-free interface between the fixed jacket and the telescope jacket.
Abstract:
A self-de-lashing power-rake mechanism of an adjustable steering column assembly of a vehicle is provided. The power-rake mechanism includes a jacket, rake bracket coupled to the jacket, and rake bolt extending through the jacket and bracket. At least one pivot bushing is disposed between the jacket and bracket and configured to receive and radially constrict around the bolt. A fastener is configured to be positioned onto the bolt, tightened, and seated on the bracket. The bolt is forced through the fastener, bracket, bushing, and jacket. The bolt is seated on the bracket as the fastener is tightened and draws the bolt, fastener, bracket, bushing, and jacket together as the fastener is being seated on the bracket, thereby de-lashing respective interfaces defined between and among the bolt, fastener, bracket, bushing, and jacket. A steering column assembly including the mechanism is also provided.

An axially adjustable steering column assembly includes an upper jacket. And a lower jacket. The steering column assembly further includes a column mounting bracket, wherein the lower jacket is operatively coupled to the column mounting bracket and translates relative to the column mounting bracket, wherein the column mounting bracket defines a first set of tapered rail slots, each of the first set of tapered rail slots disposed on opposite sides of the column mounting bracket and extending longitudinally along the column mounting bracket, wherein the lower jacket defines a second set of tapered rail slots, each of the second set of tapered rail slots disposed on opposite sides of the lower jacket and extending longitudinally along the lower jacket. The steering column assembly yet further includes a first pair of sliding wedge bushings disposed within the first set of tapered rail slots.
Abstract:
A no-back spring apparatus includes a body having an annular shape extending between an outer diameter and an inner diameter, the body comprising a first axial side and a second axial side, the second axial side including a flat portion extending from the inner diameter toward the outer diameter. The no-back spring apparatus also includes a plurality of retaining fingers circumferentially spaced from each other and integrally formed with the body and extending radially outwardly from the outer diameter. The no-back spring apparatus further includes a plurality of spring elements integrally formed with the body, each of the plurality of spring elements including a tab portion extending radially inwardly from the inner dimeter.

Abstract:
A steering column assembly includes a telescope drive bracket. The steering column assembly also includes a first jacket operatively coupled to the telescope drive bracket. The steering column assembly further includes a second jacket, wherein the first jacket is telescopingly moveable relative to the second jacket. The steering column yet further includes a collapse limiting feature having a cam portion and a blocking portion, wherein the blocking portion defines a first range of travel of the first jacket in a first position, wherein contact between the telescope drive bracket and the cam portion biases the blocking portion out of a first jacket path to allow a second, greater range of travel for the first jacket.
