A power spring (10) for a seat belt retractor (24) is described. A seat belt retractor (24) for a seat belt device of a vehicle is also proposed. The invention relates to a seatbelt retractor comprising: a seatbelt reel (26) which is mounted in a seatbelt retractor housing (28) so as to be rotatable about a central axis (26a); and the power spring (10) is used for rotating and resetting the safety belt reel (26). In the state in which the power spring (10) has been fitted in the belt retractor (24), the power spring (10) has a plurality of spring coils (30), which extend in a substantially helical nesting manner. The power spring (10) is arranged substantially concentrically with respect to the central axis (26a).

    描述了一种用于安全带卷收器(24)的动力弹簧(10)。还提出了一种用于车辆的安全带装置的安全带卷收器(24)。该安全带卷收器包括:安全带卷轴(26),该安全带卷轴以可围绕中心轴线(26a)旋转的方式支承在安全带卷收器壳体(28)中;以及用于使安全带卷轴(26)旋转复位的动力弹簧(10)。在此,动力弹簧(10)在其已装配在安全带卷收器(24)中的状态下具有多个弹簧圈(30),这些弹簧圈大体上呈螺旋形地嵌套式延伸。动力弹簧(10)大体上相对于中心轴线(26a)同心地布置。
