Abstract
A steering wheel and column assembly is provided for deployment on a vehicle. In one embodiment, the steering wheel and column assemblies comprises: (i) a steering column housing, (ii) a rotatable steering assembly, and (iii) a torsional damper device. The rotatable steering assembly includes a steering column shaft, which is rotatably coupled to the steering column housing, and a steering wheel, which is fixedly coupled to the steering column shaft. The torsional damper device includes a stator body, which is fixedly coupled to the steering column housing, and a rotor body, which is fixedly coupled to the rotatable steering assembly. The rotor body frictionally engages the stator body to produce a predetermined coulomb torque frictional resistance.
