Abstract

Oggetto dell'invenzione è un dispositivo di precaricamento azionato da un attuatore rotativo il quale comprende un generatore di gas ed un attuatore rotativo che viene azionato in rotazione dal gas pressurizzato alimentato dal generatore di gas e trascina una bobina o rocchetto di riavvolgimento della cintura. La parete divisoria sul cilindro che separa la sezione di pressione della camera di funzionamento dalla sezione di scarico riceve un organo di guarnizione di tenuta il quale viene sollecitato elasticamente da una molla in impegno con la porzione di corpo del rotore. L'organo di guarnizione di tenuta impedisce al gas di passare attraverso la parete divisoria dalla sezione di pressione alla sezione di scarico.
