Abstract: A safety belt arrangement for motor vehicles. The arrangement includes a safety belt and a belt roller from which the belt is retracted and withdrawn. The roller is pre-tensioned in the belt wind-up direction the unwinding of the belt is blocked in the case of an accident. The safety belt arrangement includes a belt deflection apparatus that includes a deflection roller. The belt is guided from the belt roller to the deflection roller so that the belt can be deflected as it approaches the passenger. The deflection roller is movable away from the passenger by a spring force in the case of an accident. Normally, the deflection roller is fixed in the against the spring force by a retainer mechanism. The retainer mechanism releases the deflection member in the event of an accident. A retraction force on the belt moves the passenger back into the normal seated position.
