OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de Ia presente memoria descriptiva, se refiere a un procedimiento de detección y medición de severidad de impactos en Ia cabeza de usuarios de casco de protección y al dispositivo para dicha detección y medición, aportando a Ia función a que se destina varias ventajas e innovadoras características, que se describirán en detalle más adelante, las cuales suponen una destacable mejora frente a los sistemas actualmente conocidos en el mercado para el mismo fin.The invention, as expressed in the statement of the present specification, refers to a method of detection and measurement of severity of impacts on the head of protective helmet users and the device for said detection and measurement, contributing to the function of that several advantages and innovative features are destined, which will be described in detail below, which represent a remarkable improvement over the systems currently known in the market for the same purpose.
Más en particular, el objeto de Ia invención se centra en un procedimiento de detección y medición de severidad de impactos en Ia cabeza de usuarios de casco de protección mediante Ia utilización de un dispositivo con un elemento amortiguador en el interior del casco, el cual se basa en Ia medición, mediante sensores, de Ia deformación de dicho relleno de protección generando una señal o señales, que varían según el grado de deformación de dicho material de relleno, suministrando información de Ia localización de Ia zona o zonas de impacto y Ia severidad del mismo que es enviada a un sistema de comunicación, presente en el propio caso, en el vehículo o es portado por el individuo, y comunica con un servicio de emergencias enviando datos relevantes del accidente.More particularly, the object of the invention focuses on a method of detection and measurement of severity of impacts on the head of protective helmet users by means of the use of a device with a damping element inside the helmet, which is based on the measurement, by means of sensors, of the deformation of said protection filler generating a signal or signals, which vary according to the degree of deformation of said filler material, providing information on the location of the area or zones of impact and the severity of the same that is sent to a communication system, present in the case itself, in the vehicle or is carried by the individual, and communicates with an emergency service sending relevant data of the accident.
Así, el dispositivo preconizado permite detectar, en caso de accidente, Ia severidad de un impacto sobre Ia cabeza del usuario de un casco que incorpora dicho dispositivo, permitiendo, además opcionalmente, determinar Ia localización concreta del mismo, facilitando con ello las labores de los equipos de emergencia que atiendan al accidentado.Thus, the recommended device allows to detect, in the event of an accident, the severity of an impact on the head of the user of a helmet that incorporates said device, also allowing, optionally, to determine the specific location thereof, thereby facilitating the work of the emergency teams that attend to the injured.
El dispositivo, si bien está eminentemente destinado para ser aplicado en cascos de protección para Ia conducción, tanto de motocicletas como de vehículos de motor, es igualmente aplicable para cualquier otro tipo de casco de protección, abarcando su implementación, tanto el campo del motor, ya sea en el terreno deportivo como en el de circulación convencional, como el campo de cualquier deporte o actividad que implique un cierto riesgo y conlleve Ia utilización de un casco.The device, although eminently intended to be applied in protective helmets for driving, both of motorcycles and motor vehicles, is equally applicable for any other type of helmet protection, including its implementation, both the motor field, whether in the sports field or in the conventional circulation, as the field of any sport or activity that involves a certain risk and involves the use of a helmet.
CAMPO DE APLICACIÓN DE LA INVENCIÓNFIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de Ia presente invención se encuadra dentro del sector técnico de Ia industria dedicada a Ia fabricación de cascos De seguridad.The field of application of the present invention falls within the technical sector of the industry dedicated to the manufacture of safety helmets.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En referencia al estado de Ia técnica debe señalarse que, hasta Ia fecha, los sistemas de detección de severidad de impacto que se han propuesto en el mercado para ser ubicados en un casco, se reducen a Ia implantación de acelerómetros de tres ejes o de varios acelerómetros cubriendo, en conjunto, los tres ejes de coordenadas.With reference to the state of the art, it should be noted that, to date, the impact severity detection systems that have been proposed in the market to be placed in a helmet, are reduced to the implementation of three-axis or multi-axis accelerometers accelerometers covering, together, the three coordinate axes.
Estos sistemas de detección, aparte de su precio prohibitivo para una gran difusión pública dentro del ámbito deportivo que incluye, entre otros, el sector de Ia motocicleta, presentan el problema de que no son capaces de discernir si el impacto producido ha sido en el casco sólo contra el suelo, por ejemplo, por Ia caída fortuita del casco, o se trata de un accidente real, en el cual Ia cabeza ha impactado y sufrido unas determinadas deceleraciones.These detection systems, apart from their prohibitive price for a wide public diffusion within the sports field that includes, among others, the motorcycle sector, present the problem that they are not able to discern if the impact produced has been on the helmet only against the ground, for example, by the accidental fall of the helmet, or it is a real accident, in which the head has impacted and suffered certain decelerations.
Además, los sistemas señalados no son capaces de detectar en qué punto concreto de Ia cabeza se ha producido el impacto. Además son sistemas voluminosos que pueden incluso ser peligrosos porque son objetos rígidos de una determinada dimensión que, al producirse el impacto a causa del accidente, pueden empeorar o agravar las lesiones que se producirían de no estar colocados en el casco.In addition, the systems indicated are not able to detect at what specific point of the head the impact has occurred. They are also bulky systems that can even be dangerous because they are rigid objects of a certain dimension that, upon impact due to the accident, can worsen or aggravate the injuries that would occur if they were not placed in the helmet.
Se constata pues, Ia necesidad de crear un sistema de detección que mejore los sistemas conocidos y se constituye como una verdadera y eficaz herramienta de detección de impactos, cuyo precio pueda fácilmente ser asumido por cualquier usuario, siendo estos los objetivos esenciales que persigue el dispositivo aquí preconizado.Therefore, the need to create a detection system that improves the known systems is established and constitutes a true and effective impact detection tool, the price of which can easily be assumed by any user, these being the essential objectives pursued by the device here recommended.
Asimismo, el solicitante tiene conocimiento de Ia existencia de Ia patente PCT /GB 2004/004229, relativa a un casco de seguridad, en Ia que se divulga un casco con un sistema para determinar los golpes que ha sufrido dicho casco, sin embargo, sus características técnicas, estructurales y de configuración son notablemente distintas al que aquí se propone, ya que en este caso, se trata de detectar Ia repercusión de los impactos sobre Ia cabeza del usuario.Likewise, the applicant is aware of the existence of the patent PCT / GB 2004/004229, relating to a safety helmet, in which a helmet with a system is disclosed to determine the blows that said helmet has suffered, however, its technical, structural and configuration characteristics are remarkably different from what is proposed here, since in this case, it is about detecting the impact of the impacts on the user's head.
EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION
Así, el procedimiento de detección y medición de severidad de impactos en Ia cabeza de usuarios de casco de protección y el dispositivo para dicha detección y medición, que Ia presente invención propone se configura como una destacable novedad dentro de su campo de aplicación ya que, a tenor de su creación y de forma taxativa, se alcanzan satisfactoriamente los objetivos anteriormente señalados como idóneos, estando los detalles caracterizadores que Io hacen posible y que Io distinguen de Io ya conocido en el mercado, adecuadamente recogidos en las reivindicaciones finales que acompañan a Ia presente memoria descriptiva.Thus, the method of detection and measurement of severity of impacts on the head of protective helmet users and the device for said detection and measurement, which the present invention proposes is configured as a remarkable novelty within its field of application since, according to its creation and in a restrictive way, the objectives indicated above are satisfactorily achieved, being the characterizing details that make it possible and that distinguish it from what is already known in the market, adequately included in the final claims that accompany the Present descriptive report.
De forma concreta, tal como se ha señalado anteriormente, el procedimiento de detección y medición de severidad de impactos en Ia cabeza de usuarios de casco de protección que Ia invención propone se basa en Ia medición mediante sensores de Ia deformación del relleno de protección. Dichos sensores generan una señal o señales, que varían según el grado de deformación de dicho relleno de protección, suministrando información de Ia localización de Ia zona o zonas de impacto y Ia severidad del mismo que es enviada a un sistema de comunicación, presente en el propio caso, en el vehículo o es portado por el individuo, y comunica con un servicio de emergencias enviando datos relevantes del accidente.Specifically, as indicated above, the procedure for detecting and measuring the severity of impacts on the head of protective helmet users that the invention proposes is based on the measurement by means of sensors of the deformation of the protective filling. Said sensors generate a signal or signals, which vary according to the degree of deformation of said protection filler, providing information on the location of the area or zones of impact and the severity thereof that is sent to a communication system, present in the own case, in the vehicle or is carried by the individual, and communicates with an emergency service sending relevant data of the accident.
Cuando a Io largo de Ia memoria descriptiva y reivindicaciones se habla de relleno de protección se entiende que el mismo cumple Ia función de elemento amortiguador de impactos. Esta amortiguación se realiza absorbiendo Ia energía del impacto a través de Ia deformación que el relleno de protección sufre debido a las fuerzas que Ia deceleración de Ia cabeza produce durante el impacto.When, throughout the descriptive report and claims, protection filler is understood, it is understood that it fulfills the function of shock absorbing element. This damping is performed by absorbing the energy of the impact through the deformation that the protective filler suffers due to the forces that the deceleration of the head produces during the impact.
Para ello, el dispositivo incorpora uno o más dispositivos sensores que se distribuyen de forma estratégica en el interior del casco, colocándose, preferentemente, en Ia superficie interior del relleno de protección del casco, debiendo señalarse que también pueden colocarse entre dos capas del relleno de protección o inserto en el mismo.For this, the device incorporates one or more sensor devices that are strategically distributed inside the helmet, preferably being placed on the inner surface of the helmet protective padding, it should be noted that they can also be placed between two layers of the padding. protection or insert in it.
Dichos sensores detectan Ia presión que Ia cabeza ejerce sobre ellos, debido a Ia deceleración provocada en Ia cabeza a causa de un impacto. Ello se consigue porque, en una realización preferida de Ia invención, los sensores son láminas piezoeléctricas que, en función de su deformación, generan un voltaje entre sus polos, el cual es proporcional a Ia deformación de Ia lámina, causada por Ia presión superficial.Said sensors detect the pressure that the head exerts on them, due to the deceleration caused in the head due to an impact. This is achieved because, in a preferred embodiment of the invention, the sensors are piezoelectric sheets that, depending on their deformation, generate a voltage between their poles, which is proportional to the deformation of the sheet, caused by the surface pressure.
En una variante alternativa de Ia invención, los sensores son de tipo capacitivos que generan una variación de su capacidad eléctrica con Ia variación de distancia entre sus caras como producto de Ia presión superficial.In an alternative variant of the invention, the sensors are of the capacitive type that generate a variation of their electrical capacity with the variation of distance between their faces as a product of the surface pressure.
Así, dichos sensores pueden ser, por ejemplo, piezoeléctricos o capacitivos en los que, por una variación de Ia presión sobre sus caras, varía Ia resistencia o Ia capacidad eléctrica del mismo, pudiendo tratarse dicha señal para conocer Ia presión ejercida en cada punto.Thus, said sensors can be, for example, piezoelectric or capacitive in which, due to a variation of the pressure on their faces, the resistance or the electrical capacity thereof varies, said signal being able to be treated to know the pressure exerted at each point.
Además, los dispositivo sensores también podrán ser de tipo piezoresistivos, que producen una variación en su resistencia en función de su deformación y/o sensores de efecto Hall, que sirven para Ia medición de campos magnéticos o corrientes o para Ia determinación de Ia posición, o sensores de cualquier otro tipo que midan Ia compresión del relleno de protección del casco, es decir, Ia parte que absorbe Ia energía del impacto.In addition, the sensor devices may also be piezoresistive, which produce a variation in their resistance depending on their deformation and / or Hall effect sensors, which are used for the measurement of magnetic or current fields or for the determination of the position, or sensors of any other type that measure the compression of the helmet protection padding, that is, the part that absorbs the impact energy.
El dispositivo, además, al contar, preferentemente, con los sensores distribuidos por todo el casco, permite Ia identificación de Ia zona concreta de impacto para una mejor previsión de los servicios de emergencia.The device, in addition, by having, preferably, with the sensors distributed throughout the helmet, allows the identification of the specific area of impact for a better forecast of emergency services.
La distribución de los sensores se realiza, según convenga en cada caso o tipo de casco, preferentemente en el interior del mismo y de manera cercana a Ia cabeza del usuario.The distribution of the sensors is carried out, as appropriate in each case or type of helmet, preferably inside it and close to the user's head.
Evidentemente, Ia reacción de los sensores en uno u otro lugar será diferente y, por tanto, el tratamiento de Ia señal en unas u otras soluciones será diferente, para obtener un resultado legible y entendible.Obviously, the reaction of the sensors in one or another place will be different and, therefore, the treatment of the signal in one or the other solutions will be different, to obtain a readable and understandable result.
Además, hay que decir que los sensores podrán ser de cualquier tamaño, desde pequeños elementos, o grandes láminas que abarquen una mayor superficie e incluso otros que pudieran tener unas dimensiones globales de contacto entre Ia cabeza y el casco.In addition, it must be said that the sensors can be of any size, from small elements, or large sheets that cover a larger surface and even others that could have overall contact dimensions between the head and the helmet.
Sin embargo, serán preferentemente de pequeño tamaño yendo incorporados en número elevado para facilitar así Ia identificación de Ia zona de impacto.However, they will preferably be small in size and incorporated in large numbers to facilitate identification of the impact zone.
Hay que decir, también, que los dispositivos sensores podrán ser de diferentes formas y tamaños, según convenga en cada caso, pudiendo ser planas o tener Ia curvatura interior del casco.It must also be said that the sensor devices may be of different shapes and sizes, as appropriate in each case, and may be flat or have the inner curvature of the helmet.
Por otra parte, cabe señalar que las láminas se conectan a un sistema de adquisición de datos o unidad de control, adecuadamente acoplado al casco, conexión que puede realizarse de forma unitaria o bien combinadas entre sí, ya sea en serie, en paralelo, en combinaciones serie-paralelo o conexión "array" (matriz de conexiones), según se desee.On the other hand, it should be noted that the sheets are connected to a data acquisition system or control unit, suitably coupled to the hull, a connection that can be made in unitary form or combined with each other, either in series, in parallel, in serial-parallel combinations or "array" connection (connection matrix), as desired.
Cabe destacar que el software de interpretación de las señales enviadas por los sensores al citado sistema de adquisición de datos ante un impacto, estará capacitado para determinar el grado de fuerza de dicho impacto, simplemente por las señales que den individualmente cada sensor o bien en su conjunto, incluso pudiendo analizar por zonas de mayor a menor grado de impacto.It should be noted that the software for interpreting the signals sent by the sensors to the aforementioned system of data acquisition before an impact, will be able to determine the degree of force of said impact, simply by the signals given individually by each sensor or in its together, even being able to analyze by areas of greater to lesser degree of impact.
Además, el dispositivo es capaz de discernir entre una caída o golpe dado al casco porque se caiga o por un impacto recibido estando colocado en Ia cabeza del usuario. Finalmente, el dispositivo preconizado contempla su asociación a un sistema de comunicación, de forma que una vez sufrida Ia caída, se dispara un aviso de emergencia, incorporando información procedente del sistema de adquisición de datos, para añadir al aviso de que se ha producido el accidente, el grado de severidad del mismo.In addition, the device is able to discern between a fall or blow given to the helmet because it falls or by an impact received being placed on the user's head. Finally, the recommended device contemplates its association with a communication system, so that once the fall is suffered, an emergency warning is triggered, incorporating information from the data acquisition system, to add to the notice that the accident, the degree of severity of it.
Con ello se persigue que los equipos de emergencia, ya desde un primer momento, sepan Ia posible gravedad del impacto y vayan convenientemente prevenidos al lugar del accidente.With this it is pursued that the emergency teams, from the outset, know the possible severity of the impact and are conveniently prevented to the place of the accident.
El descrito procedimiento de detección y medición de severidad de impactos en Ia cabeza de usuarios de casco de protección y al dispositivo para dicha detección y medición, representa, pues, una innovación de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, Ia dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The described method of detection and measurement of severity of impacts on the head of protective helmet users and the device for said detection and measurement, therefore, represents an innovation of structural and constitutive characteristics unknown until now for this purpose, reasons that together to their practical utility, they provide sufficient grounds to obtain the privilege of exclusivity that is requested.

Un sensor alternativo para realizar Ia medida directa se constituye mediante la colocación de al menos dos capas constituidas por al menos un elemento conductor y separadas entre sí por un cierto espesor del relleno de protección. La primera capa se sitúa bien entre Ia cara interior de Ia carcasa del casco y Ia parte externa del relleno de protección o embebida en el relleno de protección, mientras que una segunda capa puede ir embebida dentro del relleno de protección o en su superficie interior; ambas capas siempre estarán adecuadamente separadas como se ha mencionado antes por un cierto espesor del relleno de protección. El relleno de protección estará diseñado de forma que cuando se produzca una deformación de un determinado nivel en éste debido a Ia compresión que Ia cabeza genera en el mismo durante el impacto, se produzca el contacto entre las dos capas de conductores y se genere Ia señal apropiada. Si el sensor se constituye por dos capas como las mencionadas, éste sólo dará señal al sobrepasar un nivel de severidad predeterminado. La colocación de más de dos capas permitirá generar señales que indicarán diversos grados de severidad, tantos grados como capas existan menos 1.An alternative sensor to perform the direct measurement is constituted by placing at least two layers constituted by at least one conductive element and separated from each other by a certain thickness of the protective filler. The first layer is located well between the inner face of the helmet shell and the outer part of the protective padding or embedded in the protective padding, while a second layer can be embedded within the padding pad or on its inner surface; both layers will always be adequately separated as mentioned before by a certain thickness of the protective padding. The protective padding will be designed so that when a deformation of a certain level occurs in it due to the compression that the head generates in it during the impact, contact between the two layers of conductors occurs and the signal is generated appropriate. If the sensor consists of two layers such as those mentioned, it will only signal when it exceeds a predetermined severity level. The placement of more than two layers will allow to generate signals that will indicate varying degrees of severity, as many degrees as there are less layers 1.
