Abstract

Perfeccionamientos introducidos en cinturones de seguridad con pretensionadores de un tipo que comprende un alojamiento (1) en el cual un carretel(10) está previsto para enrollar y desenrollar automáticamente un cinto. En conjunto con distintosdispo sitivos de seguridad, el cinturon de seguridadincorpora un dispositivo de actuacion doble del eje de traba (37), de los cuales el primero es un sensor de inercia SI y el segundo es un sensor delvehículo SV, de manera de asegurar al conjuntomedios de actuacion del cinturon de seguridad ya sea por un movimiento del vehículo o por un movimientobrusco del pasajero, el mismo conjunto incluye un mecanismo pretensionador (7) el cual funciona con un eje de torcion (63) y una carga deproyeccion(75), cu ya detonacion provoca la expansion de gases en el interior de un tubo (71) lanzando un émbolo (77) contra la cremallera (78) la cual, a su vez,se desplaza a lo largo del tubo (71) para ser acumulado en el interior delcompartimento (79), pero, antes, causa una rotacion al engranaje (68) y, conello, también al carretel (10), para así enrollar el cinto del cinturon de seguridad para eliminar completamente cualquier holgura entre el mismo y elpasajero, para aumentarla seguridad.
