OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un traje de trabajo, apto para su uso permanente a bordo de una embarcación, en cualquier clima, ya que aisla térmicamente de las condiciones medioambientales, que incorpora los medios de salvamento necesarios para la supervivencia del usuario en caso de caída al agua. The present invention relates to a work suit, suitable for permanent use on board a vessel, in any climate, since it thermally insulates from environmental conditions, which incorporates the necessary rescue means for the user's survival in case of Water fall
El objeto principal de la presente invención es un traje de trabajo confortable, ergonómico y ligero, que integra todos los equipos de seguridad personal para garantizar la flotación, protección térmica y localización del usuario en situaciones de "hombre al agua" (MOB, del inglés "man overboard"), en adelante situaciones MOB. The main object of the present invention is a comfortable, ergonomic and lightweight work suit, which integrates all personal safety equipment to ensure flotation, thermal protection and user location in "man-in-the-water" situations (MOB) "man overboard"), hereinafter MOB situations.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En el estado de la técnica son conocidos multitud de dispositivos para el salvamento de personas en situación MOB, tales como, flotadores salvavidas, chalecos salvavidas, trajes de abandono, trajes secos, etc. Todos estos dispositivos ampliamente conocidos y experimentados, son dispositivos que el usuario debe colocarse en situaciones de posible naufragio, por lo que, habitualmente el usuario no los lleva puestos durante su jornada laboral a bordo de una embarcación. Por lo tanto, en caso de situaciones MOB, en las que el marinero caiga accidentalmente al agua, lo más probable es que no lleve consigo ningún dispositivo de salvamento marítimo. Las situaciones MOB son imprevisibles, por lo que no permiten al marinero anticiparse y colocarse los dispositivos de salvamento personal. Estos dispositivos de salvamento, para conferir flotabilidad al usuario, incorporan unos volúmenes de flotación pasivos y/o activos, que en cualquier caso, representan una incomodidad al usuario a la hora de realizar sus trabajos a bordo de la embarcación. Efectivamente, los dispositivos de salvamento que incorporan volúmenes pasivos, tales como corcho, porexpan, y en general cualquier material de baja densidad que flote, representan un volumen adicional sobre el cuerpo del usuario que limita su movilidad. Por otro lado, los dispositivos de salvamento que incorporan volúmenes activos, tales como flotadores o chalecos que se inflan mediante el disparo de un cartucho de CO2 comprimido, tienen el inconveniente que deben incorporar un elemento rígido y de cierto peso, como es el propio cartucho de CO2 y su soporte de activación en el propio volumen, generalmente situado en el pecho, con las molestias y peligros que ello comporta. Por lo tanto, la utilización de dichos dispositivos de salvamento por parte del marinero, o la incorporación de los mismos a su indumentaria habitual de trabajo, a parte de no garantizar su supervivencia en situaciones MOB, resultan incómodos y limitan su movilidad en situación normal de trabajo a bordo de la embarcación. El uso de cartuchos de CO2 convencionales, tiene el inconveniente adicional que su disparo se realiza de forma mecánica mediante una aguja percutora, asistida por un resorte, que perfora el tapón del cartucho cuando se disuelve una pastilla de sal soluble o a base de celulosa, en contacto con el agua. Por lo tanto, este dispositivo de disparo mecánico, a parte de no ser fiable al poder disolverse la pastilla en situaciones de alta humedad o salpicaduras, sin haber una situación real MOB, no es controlable electrónicamente. In the state of the art, a multitude of devices are known for the rescue of people in MOB situation, such as lifeguards, life jackets, abandon suits, dry suits, etc. All these devices widely known and experienced, are devices that the user must be placed in situations of possible shipwreck, so, usually the user does not wear them during his workday aboard a boat. Therefore, in the case of MOB situations, in which the sailor accidentally falls into the water, it is most likely that he does not carry any marine rescue device. MOB situations are unpredictable, so they do not allow the sailor to anticipate and place personal rescue devices. These rescue devices, to confer buoyancy to the user, incorporate passive and / or active flotation volumes, which in any case, represent an inconvenience to the user when carrying out their work on board the vessel. Indeed, rescue devices that incorporate passive volumes, such as cork, porexpan, and in general any low density material that floats, represent an additional volume on the user's body that limits their mobility. On the other hand, rescue devices that incorporate active volumes, such as floats or vests that are inflated by firing a compressed CO 2 cartridge, have the disadvantage that they must incorporate a rigid element of a certain weight, as is the own CO 2 cartridge and its activation support in the volume itself, usually located in the chest, with the discomforts and dangers that this entails. Therefore, the use of such rescue devices by the sailor, or the incorporation of them to their usual work clothes, apart from not guaranteeing their survival in MOB situations, are uncomfortable and limit their mobility in normal situation of I work on board the boat. The use of conventional CO 2 cartridges has the additional disadvantage that their firing is carried out mechanically by means of a piercing needle, assisted by a spring, which pierces the cap of the cartridge when a soluble or cellulose-based salt tablet is dissolved, in contact with water. Therefore, this mechanical firing device, apart from being unreliable to dissolve the tablet in situations of high humidity or splashes, without having a real MOB situation, is not electronically controllable.
Otra opción existente en el mercado para el disparo de los cartuchos de gas, es la activación por presión en una membrana que retiene una cuchilla, cuyo dispositivo va instalado dentro de una funda protectora dentro del volumen inflable. Este sistema ha tenido a lo largo de los años numerosos fallos que han provocado muertes, puesto que, en función de la posición de caída del marinero (horizontal o vertical), no es capaz de detectar diferencias de presión fallando su activación. Otro inconveniente de este sistema, es que el cartucho, al estar en el interior del volumen inflable, es inaccesible, por lo que no se puede realizar un correcto mantenimiento, revisión y reposición del mismo. Another option available in the market for the firing of gas cartridges, is the activation by pressure on a membrane that retains a blade, whose device is installed inside a protective sheath within the inflatable volume. Over the years, this system has had numerous failures that have caused deaths, since, depending on the position of the sailor's fall (horizontal or vertical), it is not able to detect pressure differences failing its activation. Another drawback of this system, is that the cartridge, being inside the inflatable volume, is inaccessible, so you can not make a correct maintenance, review and replacement thereof.
Otro aspecto importante en la supervivencia de un naufrago, es su protección térmica, por lo que en determinados mares con una temperatura muy fría, o en casos en que se tarde mucho en localizar y rescatar al naufrago, éste puede morir por hipotermia. El proceso de hipotermia empieza a partir de una temperatura de agua de 25°, reduciéndose el tiempo de supervivencia drásticamente, llegando a unos 15 minutos a una temperatura de agua de mar de entre 5o y 7o. En este sentido, son conocidos los trajes secos, generalmente de neopreno que evitan el contacto del agua con la piel del usuario. Si bien estos trajes secos, denominados de abandono, son eficientes bajos las diferentes normativas en vigor en el sector naval, son específicos para el abandono del buque y es imposible trabajar con ellos puestos, o permanecer a bordo por tiempo indefinido, dada su absoluta incomodidad, falta de transpirabilidad y el calor agobiante que producen. Another important aspect in the survival of a shipwreck is its thermal protection, so in certain seas with a very cold temperature, or in cases where it takes a long time to locate and rescue the shipwreck, it can die from hypothermia. The process begins hypothermia from a water temperature of 25 °, reducing the survival time drastically, reaching about 15 minutes at a temperature of sea water between 5 and 7th. In this sense, dry suits, generally made of neoprene, that avoid the contact of water with the user's skin are known. Although these dry suits, called abandonment, are efficient under the different regulations in force in the naval sector, they are specific for the abandonment of the ship and it is impossible to work with them on, or remain on board indefinitely, given their absolute discomfort , lack of breathability and the overwhelming heat they produce.
Las características de los Equipos de Protección Individual (en adelante EPI) aplicables al sector marítimo, están regulados por las normas ISO, y las características de los equipos obligatorios de seguridad que debe equipar un buque profesional ante una posible situación de hundimiento y abandono del mismo, están reguladas por el Convenio Internacional SOLAS que determina las exigencias que deben cumplir dichos equipos en cuanto a flotabilidad, protección térmica y sistemas de localización. The characteristics of the Personal Protective Equipment (hereinafter PPE) applicable to the maritime sector, are regulated by the ISO standards, and the characteristics of the mandatory safety equipment that a professional vessel must equip in the event of a possible sinking and abandonment situation. , are regulated by the SOLAS International Convention that determines the requirements that such equipment must meet in terms of buoyancy, thermal protection and location systems.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención se refiere a un traje de trabajo de uso permanente, que permitiendo realizar todas las tareas encomendadas a los tripulantes a bordo, aporta y garantiza la flotabilidad, protección térmica a bordo y protección hipotérmica en el agua, así como la localización del náufrago en situaciones MOB, además de ofrecer una confortabilidad y movilidad al usuario en situación normal de trabajo a bordo de la embarcación. Para ello, y de forma más concreta, el traje de trabajo y salvamento marítimo objeto de la presente invención comprende, una prenda confeccionada con un tejido multicapa que cubre íntegramente el cuerpo y extremidades superiores e inferiores de la persona, unos elementos de flotación pasivos y unos medios de flotación y protección térmica complementarios que se activan automáticamente en situaciones MOB. Los medios de flotación complementarios comprenden, al menos un volumen de flotación complementario, un cartucho de gas comprimido para el inflado del volumen de flotación complementario mediante una conducción flexible y un dispositivo pirotécnico de disparo integrado en el propio del cartucho de gas, cuyo dispositivo pirotécnico se activa mediante unos medios electrónicos que comprenden una placa electrónica de gestión del traje, unas baterías de alimentación, al menos dos pares sensores de presión y al menos dos pares de sensores de conductividad distribuidos sobre la superficie del traje. Adicionalmente, comprende una válvula anti-retorno, para mantener el volumen de flotación complementario inflado. The present invention relates to a work suit for permanent use, which allows performing all the tasks entrusted to the crew on board, provides and guarantees buoyancy, thermal protection on board and hypothermic protection in the water, as well as the location of the castaway in MOB situations, in addition to offering comfort and mobility to the user in normal work situation on board the boat. To do this, and more specifically, the work and maritime rescue suit object of the present invention comprises, a garment made with a multilayer fabric that completely covers the body and upper and lower limbs of the person, passive flotation elements and complementary flotation and thermal protection means that are automatically activated in MOB situations. The complementary flotation means comprise, at least one complementary flotation volume, a compressed gas cartridge for inflation of the complementary flotation volume by means of flexible conduction and a pyrotechnic firing device integrated into the gas cartridge itself, whose pyrotechnic device it is activated by electronic means comprising an electronic suit management board, power batteries, at least two pairs of pressure sensors and at least two pairs of conductivity sensors distributed on the surface of the suit. Additionally, it comprises a non-return valve, to keep the complementary float volume inflated.
Por otro lado, indicar que los medios de flotación pasivos del traje, comprenden una capa laminar de aerogel de sílice dispuesta en el interior del tejido multicapa del traje, que abarca toda la superficie del mismo. El aerogel de sílice es un material muy ligero y aislante térmico, que además confiere al traje una flotabilidad pasiva excepcional. On the other hand, indicate that the passive flotation means of the suit comprise a layer of silica airgel disposed inside the multilayer fabric of the suit, which covers the entire surface thereof. The silica airgel is a very light and thermal insulating material, which also gives the suit exceptional passive buoyancy.
Para conferir a la capa laminar de aerogel una mejor resistencia a la flexión y evitar la salida del polvo de aerogel de sílice que se pueda desprender, la capa laminar de aerogel de sílice está cubierta por ambas caras, con un tejido de forro laminado transpirable e impermeable, debidamente cerrado perimetralmente. To give the airgel laminar layer a better flexural strength and prevent the release of silica airgel dust that can be released, the silica airgel layer is covered on both sides, with a breathable laminated lining fabric and waterproof, properly closed perimeter.
El gas que contiene el cartucho, preferentemente es Helio, el cual presenta varias ventajes frente a otros gases. Se trata de un gas inerte, no tóxico ni contaminante, comprimido a alta presión lo que permite una velocidad de inflado mayor, una densidad inferior, y por lo tanto una mayor flotabilidad para el mismo volumen de gas. La utilización de Helio garantiza su absoluta seguridad intrínseca y la imposibilidad de producir chispas, llama o cualquier otro fenómeno que pueda causar daños al usuario o al entorno de trabajo. Debido a la alta presión a la que está comprimido, el cartucho contenedor es de tamaño reducido. The gas contained in the cartridge, preferably is Helium, which has several advantages over other gases. It is an inert gas, non-toxic or polluting, compressed at high pressure which allows a higher inflation rate, a lower density, and therefore a greater buoyancy for the same volume of gas. The use of Helio guarantees its absolute intrinsic safety and the inability to produce sparks, flame or any other phenomenon that may cause damage to the user or the work environment. Due to the high pressure at which it is compressed, the container cartridge is small in size.
Dicho cartucho de gas está ubicado en la zona lumbar del traje, entre las capas del tejido multicapa, y está conectado al volumen de flotación complementario mediante un tubo flexible provisto de conexiones rápidas, para el mantenimiento y reposición del mismo Said gas cartridge is located in the lumbar area of the suit, between the layers of the multilayer fabric, and is connected to the complementary float volume by means of a flexible tube provided with quick connections, for the maintenance and replacement of the same
Con el gas procedente del cartucho, se infla el volumen de flotación complementario que comprende, un flotador en forma de "U" plegado, dispuesto en un compartimento en el canesú del traje, en cuyo interior se dispone de una vejiga de igual configuración que el flotador, y cuyo flotador en forma de "U" invertida comprende una extensión en forma de capucha que protege la cabeza. Dicho flotador en forma de "U" está formado por dos lóbulos pectorales, un volumen cilindrico en la zona de la nuca, y unos volúmenes tubulares que emergen de la parte superior del volumen cilindrico de la nuca que configurarán la capucha de protección de la cabeza. Todos estos volúmenes que configuran el flotador del forma de "U" invertida, están unidos entre sí para su inflado simultáneo. With the gas coming from the cartridge, the supplementary flotation volume is inflated, comprising a folded "U" shaped float, arranged in a compartment in the suit yoke, inside which there is a bladder of the same configuration as the float, and whose inverted "U" shaped float comprises a hood-shaped extension that protects the head. Said "U" shaped float is formed by two pectoral lobes, a cylindrical volume in the neck area, and tubular volumes that emerge from the top of the cylindrical volume of the nape that will configure the head protection hood . All these volumes that make up the float of the inverted "U" shape, are joined together for simultaneous inflation.
Para facilitar el volteado del naufrago, en caso de caer boca abajo, uno de los lóbulos pectorales del flotador en forma de "U" tiene mayor volumen que la otra. To facilitate the turning of the shipwrecked person, in case of falling upside down, one of the pectoral lobes of the "U" shaped float is larger than the other.
En una realización preferente, la vejiga está compuesta por dos films de poliuretano soldados perimetralmente de forma hermética, y provista de una extensión superior en la zona de la nuca, para expandir la extensión en forma de capucha. Dicha vejiga comprende una conexión rápida para conectar la conducción flexible procedente del cartucho de gas, y un tubo oral para el inflado manual para el caso que falle el inflado automático. El compartimento del canesú que contiene el flotador en forma de "U", plegado, comprende una solapa de cierre y protección que a su vez comprende unos cierres rápidos que permiten la apertura de la solapa con el florecimiento del flotador en forma de "U" invertida. Por delante del traje, en la zona pectoral, se disponen de unos compartimentos compuestos por una solapa de material textil, fijadas por el extremo interior a los bordes de la cremallera central del traje, y por el extremo exterior a la superficie pectoral del traje a través de un fuelle que permite la expansión de dichos compartimentos con el inflado de los lóbulos pectorales del flotador. Estas solapas pectorales, por su extremo superior están fijadas sobre la solapa de cierre del canesú, también mediante cierres rápidos, tipo Velero® , que permiten el florecimiento y expansión de los diferentes volúmenes del flotador. Para que las solapas pectorales queden bien cerrada por su extremo exterior, el fuelle comprende unas tiras de cierre tipo Velero® que lo mantienen plegado. Dicha tiras se separan con el inflado del flotador para permitir la expansión del fuelle, y por lo tanto de la solapa, quedando los lóbulos pectorales del flotador debidamente protegidos dentro del compartimento. In a preferred embodiment, the bladder is composed of two hermetically welded polyurethane films, and provided with an upper extension in the neck area, to expand the hood-shaped extension. Said bladder comprises a quick connection to connect the flexible conduit coming from the gas cartridge, and an oral tube for manual inflation in the event that automatic inflation fails. The yoke compartment containing the folded "U" shaped float comprises a closing and protection flap which in turn comprises quick closures that allow the flap to open with the "U" shaped float blooming. inverted In front of the suit, in the pectoral area, there are compartments composed of a flap of textile material, fixed by the inner end to the edges of the central zipper of the suit, and by the outer end to the pectoral surface of the suit a through a bellows that allows the expansion of said compartments with the inflation of the pectoral lobes of the float. These pectoral flaps, by their upper end are fixed on the yoke closure flap, also by means of quick closures, type Velero®, which allow the float to bloom and expand the different volumes of the float. In order for the pectoral flaps to be tightly closed at their outer end, the bellows comprises Velero® type closure strips that keep it folded. Said strips are separated with the inflation of the float to allow the expansion of the bellows, and therefore of the flap, leaving the pectoral lobes of the float properly protected within the compartment.
El flotador en forma de "U" está fijado al traje, por su rama central al borde del canesú, y por los extremos de los lóbulos pectorales en sendos puntos de un cinturón. Dichas fijaciones son practicables para poder extraer el flotador en forma de "U" del traje. De este modo, en situación normal de trabajo, el flotador está plegado en su compartimento de una forma totalmente integrada en el traje, permitiendo una total movilidad al usuario. El cinturón, que está fabricado con materiales de alta resistencia, está fijado a la cintura del traje mediante costuras de alta resistencia y seguridad, y comprende una gaza para el izado del naufrago y un dispositivo de cierre y ajuste a la cintura del usuario. The "U" shaped float is fixed to the suit, by its central branch at the edge of the yoke, and by the ends of the pectoral lobes at two points of a belt. These fixings are practicable to be able to remove the "U" shaped float from the suit. Thus, in a normal working situation, the float is folded in its compartment in a completely integrated way in the suit, allowing total mobility to the user. The belt, which is made of high resistance materials, is fixed to the waist of the suit by means of high resistance and safety seams, and comprises a gauze for lifting the shipwrecked and a closure and adjustment device to the user's waist.
El traje, de una sola pieza, se cierra mediante una cremallera semi-estanca, protegida interior y exteriormente por sendas solapas que minimizan la posible entrada de agua. The suit, in one piece, is closed by a semi-watertight zipper, protected inside and out by two flaps that minimize the possible entry of water.
Lo sensores de presión para la activación de los medios de flotación complementarios se activan cuando la diferencia de presión entre dos de ellos está comprendida entre 10 y 20 milibares. Para la activación de los medios de flotación y protección térmicos complementarios, primero deben activarse los sensores de continuidad. Cuando los sensores de continuidad se han activado, los sensores de presión empiezan a funcionar, y cuando éstos detectan una diferencia de presión, entre dos de ellos, comprendida entre 10 y 20 milibares, entonces la placa electrónica de gestión del traje, acciona el dispositivo pirotécnico para el disparo del cartucho de gas. La detección de conductividad por presencia de agua, activa la placa electrónica de gestión del traje. Si transcurridos un periodo de tiempo comprendido entre 5 y 20 segundos, no se recibe señal de los detectores de presión, la placa electrónica de gestión del traje vuelve a desactivarse, pasando a un estado de letargo sin consumo de baterías. The pressure sensors for the activation of the flotation means complementary are activated when the pressure difference between two of them is between 10 and 20 millibars. For the activation of the supplementary thermal flotation and protection means, the continuity sensors must first be activated. When the continuity sensors have been activated, the pressure sensors start to work, and when they detect a pressure difference, between two of them, between 10 and 20 millibars, then the electronic suit management board activates the device pyrotechnic for firing the gas cartridge. Conductivity detection by the presence of water activates the electronic suit management board. If after a period of time between 5 and 20 seconds, no signal is received from the pressure detectors, the electronic suit management board is deactivated again, going into a state of lethargy without battery consumption.
Para generar calor adicional, los medios de protección térmica complementarios comprenden, unos contenedores flexibles adicionales distribuidos en el interior del traje, donde tiene lugar una reacción química exotérmica que genera calor, y unos sensores de temperatura distribuidos en el interior del traje que, a través de la placa electrónica de gestión del traje, activan la reacción. La reacción química exotérmica comprende una de las siguientes reacciones: disolución saturada de acetato de sodio en agua; oxido de calcio y agua; polvo de hierro y agua; o cloruro de calcio y agua To generate additional heat, the complementary thermal protection means comprise additional flexible containers distributed inside the suit, where an exothermic chemical reaction takes place that generates heat, and temperature sensors distributed inside the suit which, through of the electronic suit management board, activate the reaction. The exothermic chemical reaction comprises one of the following reactions: saturated sodium acetate solution in water; calcium oxide and water; iron powder and water; or calcium chloride and water
Para facilitar la localización del naufrago, la extensión en forma de capucha del flotador en forma de "U" comprende una antena emisora de radiofrecuencia. Asimismo, comprende un indicador luminoso de posicionamiento del naufrago, y un sensor de luminosidad para una óptima gestión de su consumo.

El sistema de activación y gestión del traje está controlado por la placa electrónica de gestión del traje principal, de forma automática a través de la información recibida de los sensores de conductividad y presión del traje. Tan pronto recibe las señales de una situación MOB, envía la señal al dispositivo pirotécnico para el disparo del gas contenido en el cartucho, e inmediatamente procede a la activación del sistema de radiolocalización, encendido del indicador luminoso de posicionamiento del naufrago, y activación de los sensores de temperatura corporal. Si en algún momento se detecta que la temperatura del cuerpo baja, acercándose a los 35°, la placa electrónica de gestión del traje activa la reacción química exotérmica de los contenedores flexibles para elevar la temperatura del interior del traje. Este control de temperatura corporal y activación de reacciones químicas exotérmicas, se mantiene hasta agotar todas las cargas térmicas incorporadas en el traje, que preferentemente serán siete. The suit activation and management system is controlled by the electronic main suit management board, automatically through the information received from the suit's conductivity and pressure sensors. As soon as it receives the signals of a MOB situation, it sends the signal to the pyrotechnic device for the firing of the gas contained in the cartridge, and immediately proceeds to the activation of the radiolocation system, turning on the indicator light of the shipwreck positioning, and activating the body temperature sensors If at any time it is detected that the body temperature drops, approaching 35 °, the electronic suit management plate activates the exothermic chemical reaction of the flexible containers to raise the temperature inside the suit. This control of body temperature and activation of exothermic chemical reactions is maintained until all thermal loads incorporated in the suit are exhausted, which will preferably be seven.
Todo el sistema de radiolocalización, indicador luminoso de posición y protección térmica permanece activo hasta que el naufrago es recogido del agua y se procede a su apagado. The entire radiolocation system, position indicator light and thermal protection remain active until the shipwreck is collected from the water and is switched off.
La placa electrónica principal de gestión del traje se programa y se testea mediante un dispositivo de control, que vía inalámbrica, realiza el testeo de todos los sensores, estado de carga de las baterías, correcto funcionamiento del indicador luminoso de posición, estado del cartucho de gas y estado del dispositivo pirotécnico, informando al usuario del estado del traje, mediante unos indicadores luminosos de colores. The main electronic board of management of the suit is programmed and tested by means of a control device, that wirelessly, performs the testing of all the sensors, state of charge of the batteries, correct operation of the indicator light of position, state of the cartridge of gas and state of the pyrotechnic device, informing the user of the status of the suit, using colored indicator lights.
Si el test diese algún tipo de fallo, el traje cuenta, tal y como hemos indicado anteriormente, con una placa electrónica auxiliar de gestión del traje, totalmente independiente de la principal, que se activa y testea manualmente. El control de esta placa electrónica auxiliar se realiza mediante un mando, instalado en la solapa del traje, con el mismo sistema de test que la principal. If the test gives some type of failure, the suit counts, as we have indicated previously, with an electronic auxiliary board for managing the suit, totally independent of the main one, which is activated and tested manually. The control of This auxiliary electronic board is made by means of a control, installed on the suit flap, with the same test system as the main one.

A la vista de las figuras reseñadas, puede apreciarse como el traje de trabajo y salvamento marítimo comprende una prenda confeccionada (1 ) con un tejido multicapas que más adelante explicaremos, que cubre íntegramente el cuerpo y extremidades superiores e inferiores, provisto de una cremallera (2) que va desde el cuello hasta la ingle, para facilitar su colocación. En la zona del canesú (24), la prenda confeccionada (1 ) dispone de un compartimento (3) cerrado por un solapa (4), cuyo cierre se realiza mediante cierres rápidos tipo corchetes o Velero® (5), en cuyo interior se dispone de un flotador (6) en forma de "U" invertida debidamente plegado que se inflará en situaciones MOB. In view of the figures outlined, it can be seen how the work and maritime rescue suit comprises a garment made (1) with a multilayer fabric that we will explain later, which completely covers the upper and lower body and extremities, provided with a zipper ( 2) that goes from the neck to the groin, to facilitate its placement. In the area of the yoke (24), the ready-made garment (1) has a compartment (3) closed by a flap (4), whose closure is made by means of quick clasps type square brackets or Velero® (5), inside which It has a float (6) in the form of a "U" inverted properly folded that will inflate in MOB situations.
Para el inflado del flotador (6) el traje comprende un cartucho (7) de gas comprimido a alta presión, en el presente ejemplo de realización Helio, a través de un tubo flexible (8) y un dispositivo pirotécnico (9) de disparo del cartucho (7) de gas accionado eléctricamente. Dicho dispositivo pirotécnico, se activa mediante unos medios electrónicos, que comprenden una placa electrónica de gestión del traje (13), unas baterías de alimentación (27), al menos dos pares de sensores de presión (17) y al menos dos pares de sensores de conductividad (16) distribuidos sobre la superficie del traje. En el presente ejemplo de realización, el tubo flexible (8) comprende una válvula anti-retorno (10) para asegurarse que el Helio se mantiene confinado en el flotador (6). For inflation of the float (6) the suit comprises a cartridge (7) of compressed gas at high pressure, in the present example Helio, through a flexible tube (8) and a pyrotechnic device (9) for firing the electrically operated gas cartridge (7). Said pyrotechnic device is activated by electronic means, comprising an electronic suit management board (13), power batteries (27), at least two pairs of pressure sensors (17) and at least two pairs of sensors of conductivity (16) distributed over the surface of the suit. In the present embodiment, the flexible tube (8) comprises a non-return valve (10) to ensure that Helium is kept confined in the float (6).
Tal y como hemos indicado anteriormente, el traje objeto de la presente invención, no es tan solo un traje de salvamento, sino también es un traje de trabajo que el marinero llevará puesto durante su jornada a bordo de la embarcación. Por ello, el traje puede encontrarse en situaciones de falso MOB, al mojarse por el oleaje, y activarse el flotador (6). Para ello, el traje de trabajo y salvamento marítimo del presente ejemplo de realización, comprende tres pares de sensores de conductividad (16) y dos pares de sensores de presión (17) distribuidos sobre la superficie del traje, según las figuras 2 y 3, debidamente conectados y gestionados por la placa electrónica (13) de gestión del traje. Por lo tanto, para que el traje detecte una situación MOB y active los medios de flotación y protección térmicos complementarios, primero la placa electrónica (13) de gestión del traje, debe recibir la información de que se han activado los sensores de conductividad (16) al mojarse, y por lo tanto, producir conductividad eléctrica. Al producirse la conductividad eléctrica en los sensores (16), la placa electrónica (13) de gestión del traje pone en funcionamiento los sensores de presión (17), y si la placa de gestión (13) del traje detecta una diferencia de presión entre dos de ellos, comprendida entre 10 y 20 milibares, correspondientes a una profundidad de 10 a 20 centímetros, entonces es cuando activa el dispositivo pirotécnico para el disparo del gas del cartucho (7). As we have indicated previously, the suit object of the present invention is not only a rescue suit, but also a work suit that the sailor will wear during his day aboard the boat. Therefore, the suit can be in situations of false MOB, to get wet by the waves, and activate the float (6). For this, the work and sea rescue suit of the present embodiment comprises three pairs of conductivity sensors (16) and two pairs of pressure sensors (17) distributed on the surface of the suit, according to figures 2 and 3, duly connected and managed by the electronic board (13) of suit management. Therefore, for the suit to detect a MOB situation and activate the supplementary thermal flotation and protection means, first the electronic board (13) for managing the suit must receive information that the conductivity sensors (16) have been activated. ) when wet, and therefore produce electrical conductivity. When the electrical conductivity occurs in the sensors (16), the electronic suit management board (13) puts the pressure sensors (17) into operation, and if the management plate (13) of the suit detects a pressure difference between two of them, between 10 and 20 millibars, corresponding to a depth of 10 to 20 centimeters, that is when you activate the pyrotechnic device for firing the gas from the cartridge ( 7).
Para una mejor integración, ergonomía y mantenimiento, el cartucho de gas (7) está ubicado en la zona lumbar del traje, entre las capas del tejido multicapa, y está conectado al flotador (6), mediante un tubo flexible (8) provisto de conexiones rápidas (1 1 ), para su reposición. For better integration, ergonomics and maintenance, the gas cartridge (7) is located in the lumbar area of the suit, between the layers of the multilayer fabric, and is connected to the float (6), by means of a flexible tube (8) provided with quick connections (1 1), for replacement.
A parte de los medios de flotación complementarios (6), el traje comprende unos medios de protección térmica y sobre todo de flotabilidad pasiva, que comprenden una capa intermedia (35) de aerogel de sílice de 2,5 milímetros debidamente encapsulado por un tejido de forro laminado transpirable (36a, 36b) cerrado perimetralmente, para evitar la salida de partículas de aerogel de sílice, tal y como puede apreciarse en la figura 16. Esta capa intermedia (35) de aerogel de sílice aporta un aislamiento térmico prácticamente total, a la vez que es permeable al vapor de agua, lo que aporta transpirabilidad y es totalmente impermeable. Su índice de absorción de agua, es prácticamente nulo. El tejido de forro laminado transpirable (36a, 36b) absorbe el posible sudor que se pueda generar por el esfuerzo físico, manteniendo el cuerpo seco. Para el encapsulado del aerogel de sílice, se emplean dos tejidos de forro laminado (36a, 36b) que se adhieren a la capa de aerogel de sílice (35) mediante dos mallas (37a, 37b) termo-fundibles de copolímero (co-poliéster) para su posterior prensado en caliente. Apart from the complementary flotation means (6), the suit comprises means of thermal protection and especially of passive buoyancy, comprising an intermediate layer (35) of 2.5 mm silica airgel duly encapsulated by a fabric of Breathable laminated lining (36a, 36b) closed perimeter, to prevent the exit of silica airgel particles, as can be seen in Figure 16. This intermediate layer (35) of silica airgel provides a virtually total thermal insulation, to while it is permeable to water vapor, which provides breathability and is completely waterproof. Its water absorption index is practically nil. The breathable laminated lining fabric (36a, 36b) absorbs the possible sweat that can be generated by physical exertion, keeping the body dry. For encapsulating the silica airgel, two laminated lining fabrics (36a, 36b) are used that adhere to the silica airgel layer (35) by means of two thermo-meltable copolymer (co-polyester) meshes (37a, 37b) ) for later hot pressing.
Cuando la placa electrónica (13) de gestión del traje detecta una situación MOB, acciona el dispositivo pirotécnico (9) liberando el gas contenido en el cartucho (7), tal y como hemos indicado anteriormente, lo que hace que se infle el flotador (6) que se encuentra debidamente plegado en el compartimento (3), rellenado todo su volumen y expandiéndolo en toda su configuración geométrica. La expansión del flotador (6) confiere al naufrago la flotabilidad y protección térmica necesaria para su supervivencia. Dicho flotador (6) una vez expandido, adopta una configuración geométrica en forma de "U invertida y comprende una extensión en forma de capucha (19) que emergen de la rama central (23) del flotador (6) en forma de "U" invertida, que protege la cabeza para su flotación y protección térmica, tal y como puede apreciarse en la figura 4. When the electronic suit management board (13) detects a MOB situation, it activates the pyrotechnic device (9) releasing the gas contained in the cartridge (7), as we have indicated previously, which causes the float to inflate ( 6) that it is properly folded in the compartment (3), filling its entire volume and expanding it in all its geometric configuration. The expansion of the float (6) gives the shipwreck the buoyancy and thermal protection necessary for its survival. Said float (6) once expanded, adopts a U-shaped geometric configuration and comprises a hood-shaped extension (19) that emerges from the central branch (23) of the inverted "U" -shaped float (6), which protects the head for floating and protection thermal, as can be seen in figure 4.
El flotador (6) está confeccionado con un material textil de naturaleza ignífuga e hidrófuga para conferirle resistencia y protección, y comprende una vejiga interior (20) de naturaleza elástica para la contención del gas procedente del cartucho (7). Dicha vejiga (20) adopta la misma configuración geométrica que el flotador (6) en forma de "U" invertida con su capucha (19) y está compuesta por dos films (12), tal y como puede apreciarse en la figura 7, soldadas perimetralmente de forma hermética. The float (6) is made of a textile material of a fire-retardant and water-repellent nature to give it resistance and protection, and comprises an inner bladder (20) of an elastic nature for the containment of gas from the cartridge (7). Said bladder (20) adopts the same geometric configuration as the inverted "U" shaped float (6) with its hood (19) and is composed of two films (12), as can be seen in Figure 7, welded perimeter tightly.
Para el caso en que el naufrago caiga boca abajo o inconsciente, se ha previsto que una de los lóbulos pectorales (21 ) del flotador (6) tenga mayor volumen de flotación, para facilitar el volteado del naufrago. Asimismo, indicar que los lóbulos pectorales (21 , 22) discurrirán por el interior del traje, entre las capas del tejido multicapa. In the case where the wreck falls face down or unconscious, one of the pectoral lobes (21) of the float (6) is expected to have a greater volume of flotation, to facilitate the wrecking of the wreck. Also, indicate that the pectoral lobes (21, 22) will run through the inside of the suit, between the layers of the multilayer fabric.
