Abstract: A steering column assembly includes a first jacket defining a first bore and a second jacket defining a second bore aligned with the first bore prior to collapse of the first jacket and the second jacket. A jacket connector extends through the bores to interconnect the first jacket and the second jacket. The jacket connector includes a pre-determined shear resistance, above which the jacket connector is sheared to permit telescopic movement between the first jacket and the second jacket. Accordingly, in response to an axial load greater than the pre-determined shear resistance of the jacket connector being applied to one of the first jacket and the second jacket, the jacket connector shears, permitting the telescopic movement. The jacket connector includes a pin defining a pin bore. The pin bore defines a cross sectional area, with the pre-determined shear resistance depending upon the cross sectional area of the pin bore.

Abstract: An adjustable steering column assembly comprises a column support bracket fixed to a vehicle structure and disposed about a steering column. A position lock selectively prevents or facilitates movement of the steering column relative to the column support bracket in an adjustment plane and defines an adjustment range of the steering column along a non-adjustment direction intersecting the adjustment plane. A lateral stabilizer biases the steering column toward a stabilized position lying within the adjustment range of the steering column along the non-adjustment direction.

Abstract: An apparatus includes a steering column assembly defining a longitudinal axis that is adjustable along at least one of a tilting and telescoping path of adjustment. The apparatus also includes a locking device associated with the steering column assembly to selectively lock and unlock steering column with respect to the at least one of tilting and telescoping paths of adjustment. The locking device includes a lever arm mounted to the steering column assembly for rotation about a rotation axis. The lever arm includes a cam surface. The locking device also includes a lock member having a cam follower surface engaged with the cam surface to move between locked and unlocked positions in response to rotation of the lever arm. The lock member is spaced from the rotation axis along the longitudinal axis.

Abstract: The present invention provides a snap-on lower bracket (14, 14a) and bearing support for supporting a collapsible steering shaft in a vehicle. The invention includes a lower steering column jacket (12, 12b) defining a depression and a bracket (14, 14a) defining a tab that cooperates with the depression. For example, when the lower steering column jacket (12, 12b) and the support bracket (14, 14a) are engaged with respect to one another, the tab engages the depression in a snap-fit relationship. The snap-fit relationship provides sufficient strength to maintain the position of the lower steering column jacket (12, 12b) relative to the vehicle during normal vehicle handling. In the event of an impact situation, the lower steering column jacket (12, 12b) can move in response to the driver impacting the steering wheel and urge the tab out of engagement with the depression.

Abstract: The invention provides a steering column for a vehicle. The steering column includes a steering column jacket defining a column axis. The steering column jacket is operable to at least partially encircle a steering shaft in a vehicle. The steering column also includes a tilt housing engaged with the steering column jacket for tilting movement about a tilt axis between a plurality of tilt positions. The steering column also includes a locking member supported for linear movement by the tilt housing. The locking member has a tip moveable outwardly with respect to the column axis to a locked position contacting the steering column jacket and inwardly towards the column axis to an unlocked position spaced from the steering column jacket.
