Abstract: 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.

Abstract: Device for winding a safety belt onto a shaft, with a principle mainspring (7), which prestresses the shaft (4) in the winding direction (a) of the safety belt (2); a ratchet wheel (12) that rotates relative to the shaft (4); a blocking device (15) for blocking the rotational movement of the ratchet wheel (12) in the winding direction (a); a balance spring (20) which transmits to the shaft (4) a prestressing force that opposes the prestressing force of the principle mainspring (7) when the ratchet wheel (12) is blocked; and a free-wheel clutch that exhibits a blocking ring (34) with teeth (35, 39) and a blocking element that interacts with said teeth (35, 39). The blocking element has two ends having an angular spacing which differs from a whole-number multiple of the divisional spacing of the teeth (35, 39).
