    • A triggering mechanism for a side airbag has a deformation sensor for determining a rate of deformation. The deformation sensor is made up of a total of two pressure-sensitive sensor elements, which are attached on a firm carrier plate parallel to the outer skin inside the vehicle. Spacer elements support the carrier plate against a structural element running parallel to the outer skin. The pressure-sensitive surface of a first sensor element in this case faces the outer skin and the pressure-sensitive surface of a second sensor element faces the structural element. The spacer elements are designed, for example, using predetermined buckling points, clip elements, etc., in such a manner that they withstand a pressure on the support plate only up to a threshold and, if the threshold is exceeded, yield abruptly. This is so that, in the event of a deformation-induced force effect, the sensor elements respond one after the other. An evaluation circuit checks the time interval between the two sensor signals and, below a critical time, sends a triggering signal to the side airbag.
    • 用于侧面安全气囊的触发机构具有用于确定变形率的变形传感器。 变形传感器由总共两个压敏传感器元件组成,这些传感器元件连接在平行于车辆外部皮肤的牢固载体板上。 间隔元件支撑承载板抵靠平行于外皮的结构元件。 在这种情况下,第一传感器元件的压敏表面面向外皮,并且第二传感器元件的压敏表面面向结构元件。 间隔元件例如使用预定的屈曲点,夹子元件等来设计,使得它们仅承受支撑板上的压力直到阈值,并且如果超过阈值,则突然地屈服。 这是因为,在变形引起的力作用的情况下,传感器元件一个接一个地响应。 评估电路检查两个传感器信号之间的时间间隔,并且在临界时间之下,向侧面安全气囊发送触发信号。
