Abstract: A steering wheel and column assembly for a vehicle includes a steering column housing and a steering column shaft rotatably coupled to the steering column housing. A steering wheel includes a central hub coupled to the steering column shaft and a steering wheel rim connected to the central hub by one or more spokes extending radially from the central hub. A dampening system cooperates with the steering wheel and includes at least one mass damper body disposed adjacent to central hub. One or more vibration damping elements extend at least partially through the at least one mass damper body and the central hub. One or more resilient support members cooperate with the at least one mass damper body, central hub and the one or more vibration damping elements to absorb vibrations in the steering wheel and column assembly.

Abstract: An actuation apparatus includes a module movably tethered to a base member. Each of the module and base member include a plurality of magnetic elements aligned in a plurality of paired magnet sets such that in a non-actuated condition a repulsive magnetic force generated by each paired magnet set causes separation of the module and base member. Application of an actuation force to an actuation surface of the module, in opposition to the magnetic repulsive force, causes movement of the module toward the base member such that contact is made between terminals defined by the magnetic elements of at least one of the paired magnet sets, to generate an output signal. In an illustrative example, the base member is a steering wheel armature of a vehicle and the module is a wheel hub assembly including an air bag and a hub cover defining the actuation surface.
