Abstract

LA INVENCION SE REFIERE A UNA COBERTURA DE SACO DE GAS PARA SISTEMA DE RESPALDO DE OCUPANTES DE UN VEHICULO, CON UNA LINEA (18) DE DESGARRE QUE SE APLICA EN EL LADO INTERIOR DE LA COBERTURA HASTA OBTENER UN ESPESOR DE PARED RESIDUAL PREVIAMENTE DETERMINADO, ASI COMO A UN PROCEDIMIENTO PARA SU ELABORACION. LA COBERTURA SE CARACTERIZA DE TAL MODO, QUE COMO PARTE COMPONENTE PRINCIPAL MUESTRA UNA O MULTIPLES CAPAS (10,12,14) APLICADAS EN UNION INTIMA UNA CON OTRA A BASE DE UN MATERIAL QUE SE ELIGE A PARTIR DEL GRUPO COMPUESTO POR ALEACIONES ELASTOMERICAS DE UN POLIMERO TERMOPLASTICO CON UN TERPOLIMERO EPDM NO RETICULADO, PARCIALMENTE RETICULADO O COMPLETAMENTE RETICULADO, COPOLIMEROS DE BLOQUE DE POLIESTER ALTERNADOS Y BLOQUES DE POLIETER ASI COMO COPOLIMEROS DE BLOQUE DE POLISTIROL Y POLIOLEFINAS. EL ESPESOR DE PARED RESIDUAL A TRAVES DE LA PARTE ESENCIAL DEL DESARROLLO DE LA LINEA DE DESGARRE ALCANZA DESDE 0,3 HASTA 1 MM Y DE TAL FORMA QUE LA LINEA (18) DE DESGARRE, PARTIENDO DEL LADO INTERIOR DE LA COBERTURA, SE REDUCE DE FORMA CONTINUA EN DIRECCION SOBRE EL LADO EXTERIOR. LA LINEA (18) DE DESGARRE SE APLICA CON LA AYUDA DE UN LASER EN EL LADO INTERIOR DE LA COBERTURA.
