A device for retracting a seatbelt, having a shaft and main drive spring which prestresses the shaft in a retracting direction of the seatbelt, and a locking wheel rotatably arranged relative to the shaft, and a blocking device with a locking lever for blocking a rotational movement of the locking wheel in the retracting direction, and a compensating spring arranged such that when the locking wheel is blocked, said compensating spring transmits to the shaft a prestressing force counteracting the prestressing force of the main drive spring. The blocking device has a switching lever for activating the locking lever, the switching lever being arranged pivotably about an axis which is parallel to the axis of the shaft, and has a first engagement element and a second engagement element which is guided on a positive cam of a control disk which is connected in a rotationally fixed fashion to the shaft.
