A safety belt reeling device for a vehicle has a housing and a reeling shaft with attached belt rotatably connected in the housing. A blocking mechanism for blocking the reeling shaft is controlled by a control system that has a vehicle-sensitive and/or a belt-sensitive sensor. The control system has a control disk with outer toothing rotatably connected to the reeling shaft. The blocking mechanism includes a locking pawl for engaging the outer toothing and locking the control disk. The blocking mechanism includes a solenoid responsive to the sensor and acting on the locking pawl such that, when the solenoid is excited, the locking pawl is in a release position out of engagement with the outer toothing, and, when the solenoid is not excited, the locking pawl is in a locking position engaging the outer toothing. A securing device has a follower securing in a first position the locking pawl in its release position, when the belt is in a rest position completely wound onto the reeling shaft and the solenoid is not excited. In a second position it releases the locking pawl at a preset removal state of the belt. The follower is connected frictionally to the reeling shaft such that upon a return movement of the reeling shaft the locking pawl is released. The follower, in the first position, directly loads the locking pawl. A reducing gear system is connected to the reeling shaft and includes a gear wheel with reversal of direction of rotation relative to the reeling shaft. The gear wheel has a control cam securing the locking pawl in its release position when the belt is in its rest position.
