ABSTRACT:
A sensor serves to detect acceleration, in particular for triggering passenger protection devices (air bags) in motor vehicles. A spring-restrained inertial mass subjected to the acceleration which is to be measured is deflected, and the deflection is detected with respect to a locally fixed reference point. Upon the exceeding of an acceleration threshold, a trigger signal is generated. A mass-restrained body has a first photoconductor, one end of which is acted upon by a light source. Depending upon whether it is in the state of rest or in a state of deflection dependent upon acceleration, the other end of the photoconductor is located opposite one of various photoconductors, which are connected to photo elements.
