Abstract

Oggetto dell'invenzione è un dispositivo pre-tenditore per un sistema di cintura di sicurezza per veicolo atto a serrare un elemento a nastro che vincola l'occupante di un veicolo mediante spostamento di un elemento del sistema della cintura in maniera tale da serrare il nastro, il quale comprende, come sorgente di forza motrice per spostare tale elemento, una molla elicoidale di torsione (1, 21) avente una porzione di estremità di base (1a, 21a) fissata al veicolo, una porzione elicoidale (1b, 21b) trattenuta in relazione guidata sul veicolo ed una porzione di estremità di azionamento (1c, 21C) associamento all'elemento così da impartire una forza di azionamento a tale elemento stesso per provocare il suo spostamento a seguito di rilascio dell'energia accumulata nella molla elicoidale. L'elemento del sistema di cintura che viene spostato dalla molla elicoidale di torsione può essere una porzione dello stesso nastro di vincolamento oppure di un nastro associato al nastro di vincolamento oppure una fibbia per mezzo della quale il nastro viene collegato al veicolo.
