Abstract

DICHO DISPOSITIVO COMPRENDE UN ELEMENTO DE POLARIZACION ELASTICO (13) Y UN GRUPO DE AMORTIGUAMIENTO (12) EL CONFORMADO ES ENTENDIDO PARA APLICAR UNA FUERZA EN EL CINTURON DE ACUERDO A UNA PREDETERMINADA DIRECCION OPUESTA AL AFLOJAMIENTO DEL CINTURON. EL DISPOSITIVO ESTA CARACTERIZADO EN QUE EL ELEMENTO DE POLARIZACION Y EL GRUPO DE AMORTIGUAMIENTO CONSTITUYEN UNA SOLA UNIDAD Y AMBOS ESTAN INCLUIDOS COMO FUERZAS DE ACTUACION DEL CINTURON AL MISMO TIEMPO Y EN UNA PREDETERMINADA DIRECCION PARA MANTENER UNA PREDETERMINADA TENSION. EL ELEMENTO DE POLARIZACION ACTUA INDEPENDIENTEMENTE DEL GRUPO DE AMORTIGUAMIENTO EN PRESENCIA DE UN AFLOJAMIENTO CONSIDERABLE DEL CINTURON, Y FORMA PARTE DEL GRUPO (12) PARA EL GOLPE DEL DISPOSITIVO EN DIRECCION OPUESTA A LA PREDETERMINADA. MEDIOS (20) PARA CONECTAR EL ELEMENTO (13) AL GRUPO (12) ESTAN FORMADOS DE UN SISTEMA ELASTICO.
