A retractor for a vehicle safety belt comprises a housing, a spindle rotatably mounted within the housing and to which one end of a safety belt is attached, the spindle being spring-biased for retracting the safety belt so that the belt is wound around the spindle. The retractor has a sensor adapted to provide a signal indicative of whether the safety belt is retracted and not in use or is withdrawn from the spindle and in use. The sensor provides said signal in dependence upon the length of safety belt withdrawn from the spindle, with means transmitting movement of the spindle to an element which activates the sensor, said means comprising a gear train, one component of which is coupled directly to the spindle. The means which transmit movement of the spindle to the element which activates the sensor cause the element to adopt a unique position upon withdrawal of any one particular length of safety belt.
