Abstract
The invention relates to a belt retractor (10) for a vehicle seatbelt, comprising a rotatable retractor shaft (14) for a belt reel (16) and bearings (18) disposed at the two axial ends of the retractor shaft (14). One of the bearings (18) has a first cylindrical bearing surface (30) and a second cylindrical bearing surface (32) axially offset against the first bearing surface (30). The bearing (18) is configured so that, when the belt reel (16) is radially loaded, the retractor shaft (14) is supported on the second bearing surface (32) and, in the radially unloaded state of the belt reel (16), the retractor shaft (14) is supported only on the first bearing surface (30).
