Abstract

The invention relates to a belt retractor (10) for a safety belt, comprising a belt spool (20) for winding the safety belt in and out, a gearbox (80), connected to the belt spool and a drive connected to the gearbox, which can drive the spool to wind in the safety belt, wherein a positive-fit overload coupling (50) is arranged between the drive and the belt spool, designed such as to operate on a positive fit basis when engaged and to uncouple on an overload in which the positive fit is released. Amongst other things, according to the invention, the positive fit overload coupling is arranged between the belt spindle (20) and the gearbox (80).
