    • A process and a mechanism for the direction-selective triggering of a passive safety device in a vehicle, with at least two acceleration transducers, where the acceleration transducers have directional sensitive axes and these have actual instantaneous orientations and are aligned in different, preferably specified reference orientations and there is an angle tolerance between the reference and the instantaneous orientations of the sensitive axes. An evaluation device is provided to correct the angle tolerance, comprising an electronic circuit which converts the signals (am 1, am 2, . . . am n) coming from the acceleration transducers to corrected output signals (a(I), a(II), . . . a(n)), which are linear combinations of the incoming signals with adjustable factors c.sub.ij : ##EQU1## This can lessen the expense of production compared to familiar mechanisms, without simultaneously reducing the measuring accuracy of the mechanism. In particular, if acceleration transducers with considerably higher angle tolerances are used, it is possible to achieve a higher level of measuring accuracy and sensitivity can be equalized and angle tolerance offset simultaneously in a single, inexpensive operation.
    • 具有至少两个加速度传感器的车辆中的被动安全装置的方向选择性触发的方法和机构,其中加速度传感器具有方向敏感轴,并且它们具有实际的瞬时取向并且在不同的,优选地指定的参考 方向,并且在基准和敏感轴的瞬时取向之间存在角度公差。 提供了一种用于校正角度公差的评估装置,包括将来自加速度传感器的信号(am 1,am 2,...,am n)转换为校正输出信号(a(I),a(II) ),... a(n)),它们是具有可调整因子cij的输入信号的线性组合:与熟悉的机制相比,这可以减少生产费用,而不会同时降低机构的测量精度。 特别地,如果使用具有相当大的角度公差的加速度传感器,则可以在单个廉价的操作中同时实现更高水平的测量精度和灵敏度的均衡和角度公差偏移。
