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.Improvements introduced in safety belts with pretensioners of a type comprising a housing (1) in which a reel (10) is provided to automatically wind and unwind a belt. Together with different safety devices, the safety belt incorporates a double actuation device of the locking shaft (37), of which the first is an SI inertia sensor and the second is an SV vehicle sensor, in order to ensure the actuation of the seatbelt acting either by a movement of the vehicle or by a sudden movement of the passenger, the same set includes a pretensioning mechanism (7) which works with a driving shaft (63) and a projection load (75), which already causes detonation causes the expansion of gases inside a tube (71) by throwing a plunger (77) against the rack (78) which, in turn, travels along the tube (71) to be accumulated in the interior of the compartment (79), but, before, it causes a rotation to the gear (68) and, with it, also to the reel (10), thus winding the seat belt belt to completely eliminate any slack between it and the passenger, for increases Security.
