The invention relates to a safety belt for a vehicle, comprising a belt strap (28), a belt retractor, a belt reel (16) and a belt reel angle sensor (22) having a first gearwheel assembly (32) and a second gearwheel assembly (36). The belt reel angle sensor (22) has a multi-stage gear unit (58) having a first gear stage having a first reduction ratio and a second gear stage having a second reduction ratio. The belt reel angle sensor (22) further comprises a rotation angle sensor (64) and a rotation angle encoder (34) associated with the rotation angle sensor (64) and a reference signal sensor (68) and a reference signal encoder (38) associated with the reference signal sensor (68). In this case the rotation angle encoder (34) is associated with the first gearwheel assembly (32) and the reference signal encoder (38) is associated with the second gearwheel assembly (36). The second gearwheel assembly (36) has relative to reference signal sensor (68) a parking position, a basic position and also a reference position, in which the reference signal encoder (38) produces a reference signal in the reference signal sensor (68). The invention also relates to a method for determining the beltstrap extension by means of such a safety belt system.
本发明涉及一种用于车辆的座椅安全带系统,包括织带(28)、安全带卷收器、卷带轴(16)、以及具有第一齿轮组件(32)和第二齿轮组件(36)的卷带轴角度传感器(22)。卷带轴角度传感器(22)包括多级传动装置(58),该多级传动装置包括具有第一减速比的第一传动级以及具有第二减速比的第二传动级。卷带轴角度传感器(22)进一步包括旋转角度传感器(64)和与旋转角度传感器(64)相关联的旋转角度发生器(34)、以及基准信号传感器(68)和与基准信号传感器(68)相关联的基准信号发生器(38)。在该情形中,旋转角度发生器(34)与第一齿轮组件(32)相关联,并且基准信号发生器(38)与第二齿轮组件(36)相关联。相对于基准信号传感器(68),第二齿轮组件(36)具有驻停位置、基础位置和基准位置,在基准位置处基准信号发生器(38)在基准信号传感器(68)中产生基准信号。本发明还涉及一种借助于这种座椅安全带系统确定织带伸展量的方法。
