Abstract

A device for attaching a steering wheel hub to a steering wheel column, while simultaneously fixing a contact unit to the steering wheel, includes a fastener that has a head part engaging in the hub and a shank that engages partially in the hub and partially in the shaft. In a locked position, the fastener engages a recess in the contact unit to prevent the steering wheel hub from rotating relative to the stator of the contact unit. In an unlocked position, the fastener partially engages the hub, partially engages the column, and disengages from the recess in the contact unit to fixedly connect the hub to the column and allow the hub, and therefore the rotor of the contact unit, to rotate.
