The invention relates to a seat-belt retractor (10), provided with a retractor shaft (12), a device (26) for determining the speed and/or angle of rotation of the retractor shaft (12), a rotating magnetic element (18), a stationary magnetic field sensor (24) and stationary element (20) that conducts the magnetic flux and is situated between the rotating magnetic element (18) and the magnetic field sensor (24). The stationary element guides the magnetic flux of the rotating magnetic element to a magnetic field sensor mounted on a circuit board. Said sensor does not have to be positioned in the immediate vicinity of the rotating magnetic element but can be mounted at a greater distance. This allows a greater degree of constructive freedom.
