Abstract
A triggering circuit for a passenger restraint system for motor vehicles is provided with at lest one belt tightener for tightening a safety belt associated with a vehicle seat. A triggering circuit evaluates the acceleration signal from an accelerometer and delivers a triggering signal to the belt tightener when a critical impact is detected. An evaluation channel detects a rear-end collision. In the evaluation channel, on the basis of the acceleration signal that appears in the event of a rear-end collision, a travel signal that characterizes backward displacement of the passenger is determined that permits the triggering signal to be output to the belt tightener when a threshold value is exceeded.
