Abstract

La invención concierne a un enrollador de cinturón con un muelle de arrollamiento operativo entre una parte de carcasa y el árbol de recogida del cinturón y con un muelle de confort conectado en serie con el muelle anterior a través de una rueda de trinquete y diseñado más débil que el muelle de arrollamiento. Para conmutar entre el muelle de arrollamiento y el muelle de confort, está previsto un engranaje reductor (23) con un segmento dentado (27) que activa a una palanca de maniobra (28), estando calculada la relación de desmultiplicación del engranaje reductor (23) de tal manera que las revoluciones al comienzo de la extracción del cinturón hasta alcanzar el punto de maniobra para desconectar el muelle de arrollamiento (19) producen menos de una revolución completa del segmento dentado (27).
