Abstract
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.
