Abstract

EN UN TENSADOR PARA SISTEMA DE CINTURON DE SEGURIDAD PARA VEHICULO SE HA PREVISTO UN ACCIONAMIENTO CON UN GENERADOR (12) DE GAS PIROTECNICO Y UNA UNIDAD (16,20) DE EMBOLO CILINDRO, CUYO EMBOLO (20) ESTA DISPUESTO EN UN PRIMER EXTREMO (161) DEL CILINDRO (16) ASI COMO UNIDO CON UNA CUERDA (22) DE TRACCION Y SE IMPULSA TRAVES DE LA PRESION DE GAS GENERADA A PARTIR DEL GENERADOR (12) GAS HACIA EL SEGUNDO EXTREMO (162) DEL CILINDRO (16) QUE MUESTRA UN ESTRECHAMIENTO. COMO SEGURIDAD DE RETENCION DEL EMBOLO SE DISPONE DE UNA PIEZA POSTIZA (18) EN FORMA DE CASQUILLO EN EL CILINDRO (16). EL ESTRECHAMIENTO FORMA UN TOPE PARA LA PIEZA (18) POSTIZA EN FORMA DE CASQUILLO. LA SUPERFICIE DE CUBIERTA INTERIOR Y/O LA SUPERFICIE DE CUBIERTA EXTERIOR DE LA PIEZA (18) POSTIZA ESTA CONFIGURADA DE FORMA PERFILADA, PARA CONSEGUIR UN ESPACIO PARA LA DEFORMACION PLASTICA DEL MATERIAL.
