Abstract

Un dispositivo di precaricamento azionato da un attuatore rotativo comprende un generatore di gas ed un attuatore rotativo il quale viene trascinato in rotazione da gas pressurizzato alimentato dal generatore di gas e trascina un rocchetto di riavvolgimento della cintura. Porzioni a flange anulari si estendono dalle pareti laterali del cilindro nella camera operativa, le porzioni a flangia essendo coassiali all'asse di rotazione del rotore ed il rotore è supportato dal cilindro per rotazione in modo da ricevere le porzioni a flangia nelle porzioni di estremità del corpo del rotore. Un organo di guarnizione di tenuta di materiale elastomero è montato sul lato della porzione a paletta del rotore che è rivolta verso la sezione di pressione della camera operativa. L'organo di guarnizione di tenuta presenta porzioni a labbro lungo i suoi bordi, le quali vengono sollecitate dalla pressione del gas nella sezione di pressione contro le pareti laterali e la parete periferica del cilindro.
