CINTURÓN DE SEGURIDAD SEAT BELT
Campo de la invención Field of the Invention
5 La invención se refiere a un cinturón de seguridad que forma parte de un sistema de retención frontal (SRF) de ocupantes de vehículos. The invention relates to a seat belt that is part of a frontal restraint system (SRF) of vehicle occupants.
Antecedentes de la invención Background of the invention
10 En lo referente a cinturones de seguridad, son conocidas diferentes configuraciones de sistemas de retención frontal (SRF) o Restrain Security System (RSS) con el objetivo de retener al ocupante de manera más eficaz respecto a los sistemas convencionales que no consiguen una retención óptima, debido entre otros factores a holguras del cinturón de seguridad y la zona del torso y/o abdomen. 10 With regard to safety belts, different configurations of frontal retention systems (SRF) or Restrain Security System (RSS) are known with the aim of retaining the occupant more effectively with respect to conventional systems that do not achieve optimal retention , due among other factors to slacks in the seat belt and the area of the torso and / or abdomen.
15 Tales configuraciones incorporan componentes como: tercer punto pirotécnico, hebilla pirotécnica, airbags de rodillas y diseños especiales en asientos entre otros. En común tienen la posición y tipo de salida de la cinta, que se realiza a través de la parte superior del montante B. Dichas configuraciones imposibilitan el diseño de una cinta variable en anchura, 15 Such configurations incorporate components such as: third pyrotechnic point, pyrotechnic buckle, knee airbags and special seat designs, among others. In common they have the position and type of exit of the tape, which is carried out through the upper part of the post B. These configurations make it impossible to design a variable tape in width,
20 grosor, y materiales. Esta característica sería deseable para conseguir, entre otras cosas, mayor adaptabilidad a la morfología de los ocupantes y un mejor comportamiento biomecánico. Se ha comprobado que los cinturones con geometría constante provocan, en caso de accidente, una elevada presión en el torso del ocupante. Este problema se agrava en 20 thickness, and materials. This characteristic would be desirable to achieve, among other things, greater adaptability to occupant morphology and better biomechanical behavior. It has been proven that belts with constant geometry cause, in the event of an accident, high pressure on the occupant's torso. This problem is exacerbated in
25 caso de impacto frontal. Ensayos y pruebas de seguridad que realizan diversas asociaciones de consumidores (Euro NCAP, ADAC, NHTSA, USNCAP, CHINANCAP) definen requisitos cada vez más severos para diversos escenarios de choque. En dichas pruebas, los fabricantes de automóviles obtienen peores resultados en lo referente a las solicitaciones en la zona pectoral, concretamente en la intrusión de 25 case of frontal impact. Safety tests and tests carried out by various consumer associations (Euro NCAP, ADAC, NHTSA, USNCAP, CHINANCAP) define increasingly severe requirements for various crash scenarios. In these tests, car manufacturers obtain worse results in relation to the solicitations in the chest area, specifically in the intrusion of
30 pecho. 30 chest
Descripción de la invención Description of the invention
Un objetivo de la invención es mejorar el comportamiento biomecánico de los 35 ocupantes en caso de impacto frontal. An objective of the invention is to improve the biomechanical behavior of the 35 occupants in case of frontal impact.

Para que la cinta pueda recogerse dentro del retractor, debe tener geometría constante. Una anchura excesiva de la cinta impediría que entrara dentro del retractor. Con la configuración convencional, la porción de cinta destinada a la zona pectoral se recoge antes que la porción de cinta destinada a la zona ventral. In order for the tape to be collected inside the retractor, it must have constant geometry. Excessive width of the tape would prevent it from entering the retractor. With the conventional configuration, the tape portion destined for the pectoral zone is collected before the tape portion destined for the ventral zone.
5 La solución propuesta por la invención comprende invertir el retractor. La salida y entrada de la cinta en el retractor se realiza primero en su porción correspondiente a la zona ventral, quedando a la vista la porción correspondiente a la zona pectoral. Con ello se consiguen varias ventajas, como se mencionan a continuación. 5 The solution proposed by the invention comprises inverting the retractor. The exit and entry of the tape in the retractor is first performed in its portion corresponding to the ventral zone, the portion corresponding to the pectoral area being visible. This achieves several advantages, as mentioned below.
10 La pretensión se realiza por la zona pélvica evitando holguras. Las holguras se han asociado al efecto submarino o “submarining” en el que el ocupante (p.e. un niño) se escurre hacia abajo en su asiento causando que parte de la cinta se coloque inadecuadamente sobre la zona blanda abdominal en lugar de mantenerse sobre los 10 The claim is made through the pelvic area avoiding gaps. The gaps have been associated with the submarine effect or “submarining” in which the occupant (e.g. a child) slips down in his seat causing part of the tape to be improperly placed on the soft abdominal area instead of being held on
15 huesos de la pelvis. 15 bones of the pelvis.
Además, se permite diseñar la porción de la cinta para la zona del torso con geometría variable (ancho, grueso, rigidez, materiales), repartiendo así las cargas en una superficie mayor por la zona pectoral. In addition, it is allowed to design the portion of the belt for the torso area with variable geometry (width, thickness, stiffness, materials), thus distributing the loads over a larger surface area through the chest area.
20 De acuerdo con la presente invención, no es preciso que haya una hebilla especial, lo que abarata costes. Tampoco es necesario un mayor número de componentes en el sistema. In accordance with the present invention, there is no need for a special buckle, which lowers costs. Nor is it necessary to have a greater number of components in the system.
25 Además, abre la posibilidad de desarrollar con un nivel de sofisticación simple, un sistema que permita una regulación de las tensiones en la cinta de manera adaptativa en función del tipo de accidente y morfología del ocupante. 25 In addition, it opens the possibility of developing, with a level of simple sophistication, a system that allows an adjustment of the tension in the belt in an adaptive way depending on the type of accident and morphology of the occupant.
La invención también permite una posición ventajosa de la hebilla cuando el cinturón 30 está recogido, ya que queda en una posición inferior respecto de un cinturón con el retractor no-invertido. The invention also allows an advantageous position of the buckle when the belt 30 is collected, since it is in a lower position with respect to a belt with the non-inverted retractor.
El sistema de retención de la invención también puede comprender adicionalmente un dispositivo que al menos permite una salida de cinta (extra) por la parte superior del 35 montante B/C de entre 20 -40cm para permitir una movilidad del ocupante en The retention system of the invention can also additionally comprise a device that at least allows a (extra) tape exit from the top of the B / C upright between 20-40cm to allow mobility of the occupant in

Con referencia a las figuras se describe un modo de realización de la invención que no ha de considerarse con carácter limitativo sino puramente ilustrativo. With reference to the figures, an embodiment of the invention is described which is not to be considered as limiting but purely illustrative.
5 En la Fig. 1 se muestra un cinturón de seguridad 20 cuando está abrochado. En la Fig. 2 se muestra el mismo cinturón recogido. En ambos dibujos se puede apreciar una porción pectoral 1 cuya forma se puede diseñar ventajosamente para mejorar la retención del ocupante. 5 In Fig. 1 a seat belt 20 is shown when fastened. The same belt is shown in Fig. 2. In both drawings a pectoral portion 1 can be seen whose shape can be advantageously designed to improve occupant retention.
10 Es posible también emplear diferentes materiales y/o geometrías para llevar a cabo este objetivo y adicionalmente mejorar la confortabilidad del cinturón 20. 10 It is also possible to use different materials and / or geometries to accomplish this objective and further improve the comfort of the belt 20.
Asimismo, se puede acoplar un dispositivo airbag que actúe en caso de accidente. Also, an airbag device that acts in the event of an accident can be attached.
15 Lo anterior es posible dado que esta porción pectoral 1 no ha de enrollarse sobre sí misma cuando el cinturón está recogido tal y como ilustra la Fig. 2. La porción ventral 2 se recoge mediante el retractor 3 a través de un reenvío inferior 25. En este ejemplo, la hebilla 22 y la lengüeta 21 pueden ser de tipo estándar. Cabe apuntar que la The above is possible since this pectoral portion 1 is not to be wound on itself when the belt is collected as illustrated in Fig. 2. The ventral portion 2 is collected by the retractor 3 through a lower forwarding 25. In this example, buckle 22 and tongue 21 can be of the standard type. It should be noted that the
20 posición de la lengüeta 21 cuando el cinturón está recogido es inferior a un cinturón convencional lo que resulta más cómodo. 20 tongue position 21 when the belt is picked up is lower than a conventional belt which is more comfortable.
De forma opcional, el cinturón puede incluir un dispositivo de movilidad 12 para permitir la salida y entrada de una parte de la porción pectoral 1 a través de un reenvío Optionally, the belt may include a mobility device 12 to allow the exit and entry of a part of the chest portion 1 through a forwarding
25 superior 24. Un pretensor 10 de carácter opcional se conecta a la porción pectoral 1 y se encarga de ajustar rápidamente el cinturón 20 en caso de colisión. Generalmente, mediante un mecanismo pirotécnico se logra pre-tensar el cinturón 20. Preferentemente, se hace desde la parte superior, de forma que no se presionaría el abdomen en caso de una eventual colocación indebida del cinturón 20. 25 top 24. An optional pretensioner 10 is connected to the chest portion 1 and quickly adjusts the belt 20 in the event of a collision. Generally, by means of a pyrotechnic mechanism, the belt 20 is pre-tensioned. Preferably, it is done from the top, so that the abdomen would not be pressed in case of an eventual improper placement of the belt 20.
30 Para regular que la presión ejercida sea adecuada, un limitador de presión 11 se puede incluir opcionalmente en la parte superior como aparece en las Fig. 1 y 2. 30 To regulate that the pressure exerted is adequate, a pressure limiter 11 may optionally be included in the upper part as shown in Figs. 1 and 2.
