Abstract: A steering column assembly having an outer jacket mounted to a support structure of a vehicle. A steering shaft is movably supported within the jacket for rotation relative to the jacket. A retainer is mounted to the outer jacket and is disposed about the shaft. A dampener is non-rotatably mounted to the retainer and defines a passageway with the shaft extending through the passageway and rotatable within the passageway. The dampener has a portion abutting the shaft and applying a frictional force between the dampener and the shaft against rotation of the shaft within the passageway relative to the dampener.

Abstract: The invention provides an apparatus including a steering column jacket defining an interior. The invention also provides a bushing disposed in the interior of the steering column jacket. The bushing includes a radially outwardly facing bearing surface and a first channel. The first channel is radially adjacent to the bearing surface. The first channel is accessible from the interior of the steering column jacket. The invention also provides injected filler material disposed in the first channel between the bushing and the steering column jacket. The filler material supports the bearing surface against radial movement relative to the steering column jacket.

Abstract: The invention provides a steering column assembly having a steering column jacket operable to support a steering shaft. The steering column assembly also includes a collar presenting a surface for guiding movement of the steering column jacket. The steering column assembly also includes a locking member operable to move in a first direction from an unlocked position to a locked position to increasingly urge the steering column jacket and the surface of the collar together to lock relative movement between the steering column jacket and the collar. The steering column assembly also includes a shaft operable to rotate in a first angular direction about a first axis to move the locking member in the first direction. The steering column assembly also includes a crank extending radially outwardly from the shaft. The steering column assembly also includes a lever operable to rotate in a second angular direction about a second axis spaced from the first axis.

Abstract: The present invention provides an apparatus for selectively preventing the collapse of a collapsible steering column of a vehicle. The invention includes a first steering column member defining first and second opposing surfaces that are fixedly spaced relative to one another. The invention also include a second steering column member connected to the first steering column member for sliding movement The second steering column member defines a third surface opposing and spaced from the first surface. The invention also includes a wedging member selectively moveable between the first and second surfaces for being selectively compressible between the first and third surfaces to limit the sliding movement. The invention selectively prevents the collapse of the steering column.

Abstract: An energy absorbing steering column for a motor vehicle including a housing supported on a body structure of the vehicle for translation through a linear collapse stroke in response to an impact on a steering wheel of the steering column and an energy absorber. The energy absorber includes a flat metal ribbon having a first end anchored to the housing, an unrestrained second end, a preformed first undulation near the first end looped over a stationary first roller, and a preformed second undulation tangent to the first undulation looped over a floating second roller. The first and second undulations overlap each other and are confined between a pair of parallel containment walls of the steering column housing.
