Safety device for motor vehicle, has seat with cushion and pre-stressed elastic padding element where actuator is assigned to cushion element and pre-stressing of element changes when corresponding sensor data is available

摘要

The device has sensors for detecting an accident or imminent accident. An actuator (6) is assigned to the cushion element (4a,4b). The pre-stressing of the element changes when corresponding sensor data is available. The actuator partially changes the pre-stressing of the cushion element, which is flexibly pre-stressed by a fluid-filled cushion. The degree of filling of cushion is varied by a pump or a valve.
