DETAILED DESCRIPTION

Referring now to the Figures, where the present disclosure will be described with reference to specific embodiments, without limiting same, it is to be understood that the disclosed embodiments are merely illustrative and may be embodied in various and alternative forms. The Figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

Referring to FIGS. 1 and 2, an adjustable steering column assembly 10 is shown in a lock position and an unlock position, respectively. The components of the adjustable steering column assembly 10 that move relative to other components are illustrated with dashed feature lines. The adjustable steering column assembly 10 may be a pivot or pivot and axially adjustable steering column assembly. The adjustable steering column assembly 10 includes a steering shaft 20, a jacket assembly 22, an energy absorption assembly 24, a locking assembly 26, and an actuator assembly 28.

The steering shaft 20 extends along a steering axis 30. The steering shaft 20 extends at least partially through the jacket assembly 22 along the steering axis 30. A steering wheel is configured to attach to an end of the steering shaft 20. A rotational or other input applied to the steering wheel rotates or pivots the steering shaft 20 about the steering axis 30 to pivot or rotate at least one vehicle wheel via a steering system.

The jacket assembly 22 is configured to carry or rotatably support the steering shaft 20. The jacket assembly 22 is attached to a vehicle structure, such as an instrument panel, by a support bracket 40. The jacket assembly 22 is extendable or retractable along the steering axis 30 to adjust a position of the steering wheel coupled to the jacket assembly 22 relative to an operator of the vehicle. The jacket assembly 22 is tiltable or pivotable about a pivot axis 42 that is disposed transverse to the steering axis 30 to adjust a position of the steering wheel coupled to the jacket assembly 22 relative to the operator of the vehicle.

The energy absorption assembly 24 is disposed on the jacket assembly 22. The energy absorption assembly 24 is configured to provide a drag load or force opposing stroking or translation of the jacket assembly 22 along the steering axis 30 to decelerate the adjustable steering column assembly 10 during a steering column collapse event.
