Abstract
A steering column assembly includes a steering wheel having a steering wheel rim, a steering wheel hub, and a rim extension segment. The steering column assembly also includes a motor operatively coupled to the rim extension segment. The steering column assembly further includes a jacket assembly operatively coupled to the steering wheel, wherein the jacket assembly defines a central passage extending in a longitudinal direction of the steering column assembly, wherein the central passage does not include a steering shaft therein.
Claims12
A steering column assembly comprising:
- a steering wheel having a steering wheel rim, a steering wheel hub, and a rim extension segment;
- a motor having a motor rotor operatively coupled to the rim extension segment;
- a jacket assembly operatively coupled to the steering wheel, wherein the jacket assembly defines a central passage extending in a longitudinal direction of the steering column assembly, wherein the central passage does not include a steering shaft therein, wherein the jacket assembly consists of a single, integrally formed jacket which translates during normal axial adjustment of the steering column assembly and during a crash stroke event of the steering column assembly;
- and
- a motor stator disposed radially inwardly of the motor rotor to be positioned between the motor rotor and the single, integrally formed jacket.

- a motor having a motor rotor operatively coupled to the rim extension segment;
- a jacket assembly operatively coupled to the steering wheel, wherein the jacket assembly defines a central passage extending in a longitudinal direction of the steering column assembly, wherein the central passage does not include a steering shaft therein, wherein the jacket assembly comprises an upper jacket and a lower jacket, wherein the upper jacket and the lower jacket each translate during normal axial adjustment of the steering column assembly, wherein the lower jacket is stationary during a crash stroke event of the steering column assembly;
- and
- a motor stator disposed radially inwardly of the motor rotor to be positioned between the motor rotor and the upper jacket.
