A seatbelt retractor has a belt reel (4) which rotates about an axis (16) mounted on a frame (9). A drive spring (5) drives the belt reel in the winding-on direction. A blocking device blocks the belt reel to prevent belt extension, and an electric motor (1) influences various functions of the seatbelt retractor. A rotor (2) can be selectively brought into driving relationship with the drive spring, a torsion bar (6), and the belt reel.
