Abstract

Device for the control of the addressability of the inflation of a frontal airbag according to the anatomical characteristics and the position of the passenger. The invention is an electrically operated mechanical system for controlling the directionality of the inflation of a frontal airbag according to the anatomical characteristics and the position of the passenger in order to avoid possible mismatches between the inflation of the airbag in case of accidents and the route that performs the trunk and the head of the passenger until touching the airbag. The system consists of an electrically operated mechanical system installed inside the dashboard that controls the exit direction of the bag according to the information sent by two sensors located on the seat, one to provide the height at which the passenger's head is located with respect to the base of the seat and another to provide the distance of separation of this one with respect to the board, and a microprocessor that calculates the meeting point between bag and passenger.

Descripción detallada de la invenciónDetailed description of the invention

El sistema objeto de la presente invención es un conjunto de componentes que tienen el objetivo de adaptar la dirección de hinchado de una bolsa de aire (airbag) de un vehículo automóvil en caso de accidente a las características anatómicas y a la posición del pasajero para conseguir que el punto de contacto de la cabeza del pasajero con el airbag sea siempre el correcto.The system object of the present invention is a set of components that aim to adapt the inflation direction of an airbag of a vehicle car in case of accident to anatomical features and to the position of the passenger to get the contact point of The passenger's head with the airbag is always correct.

El sistema está formado por un microprocesador (1) que contiene la posición equivalente de encuentro entre bolsa de aire (airbag) hinchada y cabeza del pasajero, según la información que suministra el sensor de posición del asiento (2), instalado en las guías de regulación longitudinal del asiento, y el sensor de altura del pasajero (3).The system consists of a microprocessor (1) containing the equivalent meeting position between the stock market of swollen airbag and passenger head, according to information provided by the seat position sensor (2), installed in the longitudinal adjustment guides of the seat, and the passenger height sensor (3).

El sistema mecánico para el control de la dirección de hinchado de la bolsa de aire se encuentra instalado en el interior tablero (4) y consta de dos partes principalmente. Por una banda se tiene el subsistema de regulación de ángulo del contenedor (5) de la bolsa de aire (6). Este subconjunto está formado por un accionamiento eléctrico lineal mediante un motor paso a paso (7) con un engranaje de dientes rectos (8) y una cremallera (9) de dientes rector y con perfil parabólico. Este sistema se instala en un lateral de la base del contenedor (5) de la bolsa del airbag mientras que el otro lateral se encuentra articulado por un eje fijo (10) al tablero (4). Para el bloqueo de este sistema se han instalado unos frenos electromagnéticos (11) en la cremallera que únicamente permiten el movimiento del sistema cuando el motor paso a paso (7) está accionando el sistema, permaneciendo completamente fijado frente a la presión que recibe el conjunto durante el hinchado del airbag.The mechanical system for the control of air bag inflation direction is installed in The interior board (4) and consists of two parts mainly. By a band has the angle adjustment subsystem of the container (5) of the air bag (6). This subset is formed by a linear electric drive by means of a motor step by step (7) with a straight tooth gear (8) and a rack (9) of rector teeth and with parabolic profile. This system is installed on one side of the base of the container (5) of the airbag bag while the other side is articulated by a fixed axis (10) to the board (4). For blocking This system has installed electromagnetic brakes (11) in the zipper that only allow system movement when the stepper motor (7) is operating the system, remaining completely fixed against the pressure the set during airbag inflation.

Paralelamente a la regulación de la inclinación del contenedor de la bolsa del airbag, el contenedor (5) tiene una salida alargada hasta la tapa de apertura (12) del airbag y detrás de la tapa de apertura se encuentra el segundo subsistema para el correcto funcionamiento de este sistema.Parallel to the inclination adjustment of the airbag bag container, the container (5) has a elongated outlet to the opening cover (12) of the airbag and behind of the opening cover is the second subsystem for the Proper operation of this system.

Este segundo subsistema está compuesto por una tapa de apertura de airbag (12) multiperforada y con una sola unión al tablero (4), permitiendo asegurar la unión física a este cuando el airbag se dispara y la tapa se abre. Por la cara interior de la tapa se encuentra instalada una lámina metálica (13) unida a la salida alargada del contenedor (5) de la bolsa del airbag, de manera que la tapa del airbag se perfore únicamente por la sección necesaria para la salida de la bolsa del airbag y garantizando la direccionabilidad del hinchado del airbag.This second subsystem is composed of a airbag opening cover (12) multi-perforated and with a single joint to the board (4), allowing to assure the physical union to this when the airbag trips and the lid opens. On the inside of the a metal sheet (13) attached to the cover is installed elongated outlet of the container (5) from the airbag bag, so that the airbag cover is pierced only by the section necessary for the exit of the airbag bag and guaranteeing the addressability of airbag inflation.

El sistema realiza la regulación automática de todos sus componentes cuando se detecta que el pasajero ocupa el asiento, manteniendo esta regulación hasta que la plaza del vehículo sea ocupada por otro pasajero con diferentes características anatómicas. El sistema también realiza reajustes en caso que se detecte una variación de la regulación del asiento del pasajero.The system performs automatic regulation of all its components when it is detected that the passenger occupies the seat, maintaining this regulation until the square of vehicle is occupied by another passenger with different anatomical features The system also performs readjustments in if a variation of the seat adjustment of the passenger.
