Abstract

LA INVENCION SE REFIERE A UN TENSOR PARA UN CINTURON DE SEGURIDAD QUE PRESENTA AL MENOS DOS UNIDADES IMPULSORAS (10, 11) ACCIONADAS PIROTECNICAMENTE QUE SE DESPLAZAN POR GUIAS (14, 32) DENTRO DE UNA CARCASA (1). ESTAS UNIDADES IMPULSORAS PUEDEN ACOPLARSE EN SECUENCIALMENTE A UN EJE DE UN ENROLLADOR DE CINTURON DE SEGURIDAD, DOTANDOLE DE UN MOVIMIENTO GIRATORIO QUE HACE QUE EL CINTURON SE TENSE. EL TENSOR INCLUYE ASIMISMO UNA RUEDA SATELITE (2) QUE PUEDE ACOPLARSE PARA QUE GIRE CON EL EJE DE ENROLLADO, ASI COMO UNA RUEDA PLANETARIA (7) QUE ES GUIADA POR UN TRAYECTO EN FORMA DE SEGMENTO CIRCULAR ALREDEDOR DE LA RUEDA SATELITE (2). LA RUEDA PLANETARIA SE DESPLAZA POR UN ENGRANAJE (9) FIJADO EN LA CARCASA Y AL MISMO TIEMPO SE ACOPLA CON UN ENGRANAJE EXTERIOR DE LA RUEDA SATELITE (2) PARA TRANSFERIR LA ROTACION. PARA TRANSFERIR EL MOVIMIENTO DE CADA UNIDAD IMPULSORA (10, 11) A LA RUEDA PLANETARIA (7), ESTAS UNIDADES SE ENGRANAN A LA RUEDA PLANETARIA (7) A LO LARGO DE UN SEGMENTO DE MOVIMIENTO DELA MISMA. EL TENSOR DEL CINTURON PUEDE PRESENTAR UNA MANIVELA O UN BRAZO DE MANIVELA (4) MONTADO DE FORMA GIRATORIA Y CONCENTRICO CON RESPECTO AL EJE (8) DE LA RUEDA SATELITE (2), SOBRE LA CUAL SE MONTA LA RUEDA PLANETARIA (7) DE FORMA GIRATORIA Y LA CUAL, PARA TRANSFERIR EL MOVIMIENTO, PRESENTA AL MENOS UN PUNTO DE ENGRANAJE (25) PARA LAS UNIDADES IMPULSORAS (10, 11).
