A seat belt tightener has an electrical tightening drive that can be operated in dependence on sensor signals of sensors assessed in an evaluating device. The sensors detect specific vehicle dynamic conditions and transmit electrical indicating signals that are proportional to the detected condition to the evaluating device. The evaluation device compares the signals with allocated threshold values to determine whether or not a potential crash situation is present. Should a potential crash situation be present, the electrical tightening drive is controlled accordingly.

1. A seat belt tightener comprising an electrical tightening drive that can be operated in dependence on signals from an array of sensors which are assessed in an evaluating device, wherein the array of sensors comprises sensors that detect specific vehicle dynamic conditions and transmit indicating signals to the evaluating device, the evaluating device compares the received indicating signals with a respectively allocated threshold value to detect a potential crash situation and above a determined vehicle speed threshold, the evaluating device controls the electrical tightening drive when a potential crash situation has been detected, and specific indicator signals for adjusting the threshold values stored in a threshold value storage device, the specific indicator signals provide the evaluating device with data about a driving behaviour as desired by a driver.
