Abstract
A sensor system for a steering wheel of a motor vehicle is provided, characterized in that, in one form, in and/or on a steering wheel rim at least one sensor device for recording the effects of an acceleration is arranged. Rapid and effective reactions can thus be made to impact events, for example.
