A seat belt retractor with a belt shaft rotatably supported in a frame for winding up a seat belt. A blocking device blocks the belt shaft in the winding off direction. A control disk (1) is spring-loaded in the direction of winding up and with a cogging (2). A sensor device (3) inertia mass (4) and a blocking lever (5) can be deflected by the inertia mass (4), which blocks the control disk (1) by deflecting the inertia mass (4) and an engagement of the blocking lever (5) into the cogging (2) of the control disk (1). A counter gear unit (6) driven by the rotary movement of the belt shaft, and a first switching device (7) is activated by the counter gear unit (6) and blocks the control disk (1) after a first belt webbing withdrawal (A) and frees it again after a second belt webbing intake (B). A second switching device (8) is activated by the counter gear unit (6) and fixes the blocking lever (5) after a belt webbing intake (C) in a non-engagement position into the cogging (2) of the control disk (1).
