摘要： 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.

摘要： An extendable steering column assembly includes a steering shaft, an energy absorption device, and a self-locking telescope actuator. The steering shaft is configured to rotate about an axis, and includes a forward shaft portion mounted for rotation to a fixed support structure, and a rearward shaft portion mounted for rotation to a jacket. The rearward shaft portion is configured to axially translate with the jacket. The energy absorption device is engaged to the jacket. The telescope actuator includes a rod extending along a centerline, a nut threaded to the rod, and a casing in operable contact with the nut. Rotational motion along with axial translational motion is induced between the rod and the nut when at least in at least a power state.

摘要： A steering column includes a steering column component. The steering column also includes a driven assembly operatively coupled to the steering column component. The steering column further includes a driving assembly. The steering column yet further includes a connection assembly that includes a connection gear having a first set of teeth operatively connected to the driving assembly, the connection gear having a set of gear clutch teeth. The connection assembly also includes a clutch member operatively connected to the driven assembly, the driven assembly moving along an axis in response to actuation from the driving assembly and causes the provided axially adjustable steering column to be adjusted along the axis, the clutch member having a set of clutch member teeth. The clutch member teeth and the gear clutch teeth are disengaged in an overload state.

摘要： Embodiments described herein are for an absolute position sensor system integrated into a steering column assembly. The absolute position sensor system comprises: a sector connected to a rake adjustment mechanism of the steering column assembly and operable to be moved thereby; a gear coupled to the sector and operable to be rotated by the movement thereof; a magnet connected to and retained by the gear such that the magnet rotates responsive to the rotation of the gear; and a sensor device positioned below the magnet and connected to a stationary part of the steering column assembly. The sensor device is configured to: detect an angle of rotation of the magnet, where the angle of rotation of the magnet corresponds to a position of the rake adjustment mechanism.

摘要： A power actuator assembly for a steering column assembly is provided. The power actuator assembly include an electric motor. Also included is a leadscrew. Further included is a gear arrangement operatively coupled to the electric motor, the gear arrangement driving rotation of the leadscrew. Yet further included is a nut threaded to the leadscrew, rotation of the leadscrew actuating linear motion of the nut relative to the leadscrew, the nut operatively coupled to a moveable portion of the steering column assembly to actuate motion of the moveable portion. Also included is a leadscrew housing, the leadscrew extending axially through the leadscrew housing. Further included is a helical bushing disposed between a radially inner surface of the leadscrew housing and a radially outer surface of the leadscrew.

摘要： A telescoping steering column is supported by a vehicle structure, and includes a steering shaft, first, second, and third jackets, and first and second adjustment mechanisms. The steering shaft is adapted to rotate about an axis. The first jacket is adapted to rotatably support the steering shaft. The second jacket is adapted to support the first jacket, and the first jacket is constructed to slide axially with respect to the second jacket. The third jacket is adapted to support the second jacket, and the second jacket is constructed to slide axially with respect to the third jacket. The first adjustment mechanism is supported by the first and second jackets for axial movement of the first jacket with respect to the second jacket. The second adjustment mechanism is supported by the second and third jackets for axial movement of the second jacket with respect to the third jacket.
