Abstract: A steering column assembly includes an inner jacket disposed along a longitudinal axis and coupled to a host structure of a vehicle. The steering column assembly also includes an outer jacket arranged co-axially about the inner jacket and the longitudinal axis. The outer jacket is configured to translate along the longitudinal axis relatively to the inner jacket to thereby facilitate telescoping motion of the steering column assembly. The outer surface of the inner jacket and the inner surface of the outer jacket cooperate to define a telescope-inhibiting range of motion of the steering column assembly along the longitudinal axis. The steering column assembly is configured to impose telescope-resisting forces as the length of the steering column assembly decreases within the telescope-inhibiting range of motion.

Abstract: An adjustment assembly for allowing or preventing adjustment of a component and an adjustable steering column are provided. A compression bracket is configured to support the steering column, a rake bracket is configured to support the compression bracket and an actuating lever is slidingly coupled to the compression bracket and slidable along a linear travel path. A linkage assembly is connected to the compression bracket and is coupled to one end of the actuating lever and a clamping assembly is coupled to the linkage assembly and configured to release a clamping force from the component upon movement of the actuating lever from a first position to a second position, and apply a clamping force to the component upon movement of the actuating lever from the second position to the first position.

Abstract: An adjustment assembly and adjustable steering column including a linearly slidable actuating lever are provided. The actuating lever is slidable between a first position and a second position along a linear travel path. The actuating lever includes an engaging portion which engages a gear assembly. The gear assembly is connected to a clamping mechanism. The clamping mechanism is configured to apply or release a clamping force on a steering column or other component. Movement of the actuating lever between the first and second positions causes rotation of the gear assembly. Rotation of the gear assembly causes the clamping mechanism to apply or release the clamping force, depending on the direction of rotation. The adjustment assembly also includes a rake bracket to support a compression bracket.

Abstract: A steering column assembly includes a mounting bracket and a column jacket moveable relative to the mounting bracket to adjust a position of the column jacket. A rake plate is pivotably coupled to the mounting bracket and defines a rake slot having rake slot teeth. A telescope plate is pivotably coupled to the column jacket and defines a telescope slot having telescope slot teeth. A rake lock having rake lock teeth is disposed within the rake slot and a telescope lock having telescope lock teeth is disposed within the telescope slot. The rake plate and the telescope plate pivot as the rake lock and the telescope lock move into interlocking toothed engagement to avoid peak-to-peak contact between the lock teeth and the slot teeth, thereby permitting full meshing engagement between the lock teeth and the slot teeth.

Abstract: A position lock for an adjustable steering column comprises a plurality of discs stacked for rotation on a control shaft and engaged to a gear profile of a stationary bracket. The discs are engaged to the gear profile so as to be caused to rotate relatively to one another as the steering column undergoes movement in the relevant direction. The discs are configured to resist rotation relative to one another when subjected to a compressive load, and the control shaft is engaged to a cam for selectively applying a compressive load to the discs. A method for selectively controlling motion of a steering column comprises coupling motion of the steering column to the relative movements of a plurality of discs, constraining the discs to rotate relative to one another as the steering column undergoes motion in the relevant direction, and selectively adjusting resistance to relative rotation the discs.

Abstract: An exemplary adjustable steering column comprises a gear positioned and configured to cause a shaft to rotate about its central axis as the steering column telescopes. The position lock further comprises one or more telescoping friction plates arranged and configured so as to rotate with the shaft when the steering column telescopes. The position lock further comprises one or more raking friction plates, each raking friction plate being positioned in frictional contact with at least one of the one or more telescoping friction plates and configured to exhibit a different rotation than the one or more telescoping friction plates when the steering column telescopes. The shaft imposes a compressive load between the one or more telescoping friction plates and the one or more raking friction plates so as to induce friction between the telescoping friction plates and the raking friction plates and thereby resist their relative movement.

Abstract: A steering column is configured for positional adjustments in first and second directions and comprises a position lock for selectively resisting movement of the steering column. The position lock comprises a stationary bracket disposed about the steering column. A control shaft is coupled to the steering column, approximately perpendicular to the first and second directions, so as to couple movement of the steering column with translation of the control shaft. Movable lock plates are arranged on the control shaft for rotation about a central axis of the control shaft and for translation with the control shaft. Each of the movable lock-plates is positioned adjacent at least one stationary lock-plate that is retained in a substantially fixed position with respect to the stationary bracket. The one or more stationary lock-plates are configured so as to selectively provide resistance to relative movement of the one or more movable lock-plates.

Abstract: A steering column assembly of a vehicle has a rocker-arm lock device for locking an adjustable steering housing and co-extending steering shaft to a stationary bracket or chassis. For driver convenience and comfort, the steering housing and shaft are together adjustable with respect to the bracket. The rocker-arm lock device has a slot in at least one of the housing and bracket and a carrier for longitudinal movement through the slot that is substantially perpendicular to a rotation axis of the steering shaft. An indexing apparatus of the device has first and second indexing rails carried by at least one of the housing and the bracket having the first slot and a carriage engaged rigidly to the carrier. A rocker arm of the apparatus is supported pivotally to the carriage about a rocker axis disposed substantially perpendicular to the carrier.

Abstract: A steering column assembly includes a mounting bracket and a column jacket moveable relative to the mounting bracket. The mounting bracket defines a rake slot having rake slot teeth and a telescope slot having telescope slot teeth. A shaft extends through the rake slot and the telescope slot transverse to a longitudinal axis of the column jacket. A rake lock having rake lock teeth is disposed within the rake slot and a telescope lock having telescope lock teeth is disposed within the telescope slot. The shaft extends through and rotatably supports the rake lock and the telescope lock. The rake lock and the telescope lock rotate as the rake lock and the telescope lock move into interlocking toothed engagement with the slot teeth to avoid peak-to-peak contact between the lock teeth and the slot teeth, thereby permitting full meshing engagement between the lock teeth and the slot teeth.
