Abstract

A belt retractor (10) includes a frame (12) provided with locking teeth (36). A belt reel (14) is rotatably supported in the frame (12) and provided on at least one axial end with ratchet teeth (38) adapted to engage in the locking teeth (36), when the belt reel (14) is shifted from a home position into a locked position. A locking bearing (32) interacts with the belt reel (14) on the side where the ratchet teeth (38) are arranged and keeps the belt reel in the home position up to a first load threshold. A load bearing (34) interacts with the belt reel on the opposite side and keeps the latter in the home position up to a second load threshold. The first load threshold is lower than the second load threshold.
