The invention relates to a safety belt retractor (10) for a vehicle safety belt, comprising a rotatable retractor shaft (14) for a safety belt reel (16) and bearings (18) arranged on both axial ends of the retractor shaft (14). One of the bearings (18) has a cylindrical first bearing surface (30) and a cylindrical second bearing surface (32) which is axially offset with respect to the first bearing surface (30). The bearing (18) is designed in such a way that the retractor shaft (14) is supported on the second bearing surface (32) when the seat belt reel (16) is subjected to a radial load and the retractor shaft (14) is supported only on the first bearing surface (30) when the seat belt reel (16) is not subjected to a radial load.
本发明涉及一种用于车辆安全带的安全带卷收器(10),该安全带卷收器包括用于安全带卷轴(16)的可旋转的卷收器轴(14)和设置在卷收器轴(14)的两个轴向端部上的轴承(18)。所述轴承(18)之一具有圆柱形的第一轴承面(30)和相对于第一轴承面(30)轴向偏移的圆柱形的第二轴承面(32)。所述轴承(18)构造成,使得卷收器轴(14)在安全带卷轴(16)承受径向负荷时支撑在第二轴承面(32)上并且卷收器轴(14)在安全带卷轴(16)不承受径向负荷的状态中仅支撑在第一轴承面(30)上。
