A safety belt reeling device with a belt-sensitive control system, for locking the reeling shaft when safety belt removal occurs at a rate above a preset limit, has a reeling shaft and a safety belt fastened thereto. The reeling shaft is rotatable for winding and unwinding the safety belt. A vehicle-sensitive control system locks the reeling shaft when horizontally acting vehicle acceleration forces are too great. The vehicle-sensitive control system has a control disk with outer toothing and a locking lever cooperating with the outer toothing. The reeling shaft is locked when the locking lever engages the outer toothing and released when the locking lever disengages the outer toothing. The vehicle-sensitive control system has a first sensor activating the locking lever for engaging the outer toothing when a first preset threshold value, defined by government standards, for horizontally acting vehicle acceleration forces is surpassed. The vehicle-sensitive control system has a second mechanical sensor acting directly on the locking lever. It activates the locking lever for engaging the outer toothing when a second preset threshold value for the horizontally acting vehicle acceleration forces is surpassed. The second threshold value is greater than the first threshold value and represents a force magnitude equivalent to low impact accidents.
A vehicle safety belt reeling device with a belt-sensitive control system for locking a reeling shaft of the safety belt reeling device when safety belt removal occurs at a rate above a preset limit, said safety belt reeling device comprising:
