Device and method for improving at least one accident-related safety-relevant wearing property of a seat belt applied by a person sitting in a vehicle seat

摘要

Device for improving at least one accident-related safety-relevant wearing property of a seat belt (4) seated in a vehicle seat (2), comprising at least one sensor element (5) for detecting an instantaneous safety-relevant actual wearing property, at least one actuator for influencing the safety-relevant wearing property and at least one control device for controlling the actuators, wherein the control device is set up to automatically control the actuator as a function of a deviation of the safety-relevant actual wearing property detected by the sensor element (5) from a predefinable safety-relevant desired wearing property, the sensor element ( 5) is at least one fiber-optic sensor arranged in the safety belt, and the safety-relevant wearing property comprises a belt tension detected by the sensor element (5), characterized in that another safety belt is provided tsrelevante wearing property comprises at least one detected by the sensor element (5) belt contour.
