Abstract

UN TENSOR DEL CINTURON CON ACCIONAMIENTO EMBOLO/CILINDRO PIROTECNICO DISPONE DE UNA MASA SENSITIVA DEL VEHICULO, FORMADA POR UN BLOQUE DE CARCASA (14) APOYADO DE FORMA BASCULANTE, UN GENERADOR DE GAS (18) INCLUIDO EN LA MISMA Y UNA UNIDAD EMBOLO/CILINDRO (20). PARA GARANTIZAR LA LIBRE BASCULACION DEL BLOQUE DE CARCASA (14) SE HA ACOGIDO EL EMBOLO (24) CON HOLGURA AXIAL Y RADIAL EN EL CILINDRO (22). EL EMBOLO (24) SE HA DOTADO DE UNA RANURA ANULAR (50), EN LA QUE SE HA DISPUESTO UNA JUNTA ANULAR (52). SIN IMPULSION POR LA PRESION DEL GAS, LA JUNTA ANULAR (52) NO PRESENTA NINGUN CONTACTO CON LA PARED INTERIOR DEL CILINDRO (22). DEBIDO A LA IMPULSION DEL GAS, LA JUNTA ANULAR (52) ES MOVIDA A LO LARGO DE LA BASE (56) DE LA RANURA ANULAR (50) ASCENDENTE EN FORMA DE CONO, Y AL MISMO TIEMPO ES ENSANCHADA RADIALMENTE, HASTA QUE ENTRA EN CONTACTO CON LA PARED INTERIOR DEL CILINDRO (22).
