Abstract
An apparatus for noncontact transmission of signals between a steering wheel and a steering column includes an airbag triggering device and a diagnostic device on the steering wheel side. The diagnostic device monitors the function of the airbag triggering device and transmits its diagnostic signal via a rotary transfer unit to a control device located on the steering column side. A simulation circuit, which can be set as a function of the diagnostic signal to the diagnosed resistance of the triggering device, precedes the control device on the steering column side.
