BREVE EXPLICACION DE LA INVENCIONBRIEF EXPLANATION OF THE INVENTION

La invention se refiere a una un dispositivo de respaldo autoajustable que protege las lumbares y relaja la presion sobre los gluteos.The invention relates to a self-adjusting backrest device that protects the lower back and relaxes the pressure on the buttocks.

El respaldo es autoajustable lo cual implica que no hace falta ningun control ni mando sobre el mismo.The backrest is self-adjusting, which implies that no control or control is required.

El dispositivo al que se hace mention complementa a una superficie de asiento de tal modo que dicha superficie de asiento es previamente existente y lo que es objeto de la presente le anade un respaldo o mejora el ya existente.The device to which mention is made complements a seating surface in such a way that said seating surface is previously existing and what is the subject of the present adds backrest or improves the existing one.

El conjunto de respaldo autoajustable comprende una plancha movil sobre la que apoya el usuario siendo que dicha plancha pivota sobre un eje horizontal que atraviesa un primer juego de bujes unidos a la plancha, estando dicho eje asociado a un segundo juego de bujes unidos a un apoyo que puede ser el propio respaldo de la silla o sillon en donde se vaya a utilizar el respaldo autoajustable en cuyo caso lo denominaremos respaldo preexistente, o ser un respaldo fijo que forma parte del dispositivo, en cuyo caso lo denominaremos respaldo del dispositivo.The self-adjusting backrest assembly comprises a mobile plate on which the user rests being said plate pivots on a horizontal axis that crosses a first set of bushings attached to the plate, said axis being associated with a second set of bushings attached to a support which can be the chair or armchair backrest where the self-adjusting backrest is going to be used in which case we will call it a pre-existing backrest, or be a fixed backrest that is part of the device, in which case we will call it the device backrest.

Al menos uno de los juegos de bujes es regulable en altura y asl, la variation de la altura del primer juego de bujes variara el punto relativo en donde pivota la plancha alterandose la palanca mientras que la variacion de la altura del segundo juego de bujes alterara la altura a la que se encuentra la plancha.At least one of the hub sets is adjustable in height and asl, the variation in the height of the first set of bushings will vary the relative point where the plate pivots by altering the lever while the variation in the height of the second set of bushings will alter the height at which the iron is.

Entenderemos por buje cualquier elemento que sirva de soporte al eje permitiendo su giro.We will understand by bushing any element that serves as support to the axis allowing its rotation.

El respaldo del dispositivo puede tener unas dimensiones distintas en funcion, entre otras cosas, de la superficie sobre la que debe apoyar.The back of the device may have different dimensions depending on, among other things, the surface on which it must rest.

La plancha tiene una position inicial, en defecto de fuerzas aplicadas por el usuario o a voluntad de este, y un recorrido de balaceo que puede venir acotado por una posicion maxima y una minima.The plate has an initial position, in the absence of forces applied by the user or at will of the user, and a course of shooting that can be limited by a maximum and a minimum position.

La posicion ideal inicial o de reposo es preferiblemente cercana a la vertical si bien eso puede variar en funcion de la inclination del respaldo preexistente o del soporte sobre el que descanse el respaldo del dispositivo.The ideal initial or resting position is preferably close to vertical, although this may vary depending on the inclination of the pre-existing backrest or the support on which the device backrest rests.

Esta posicion de reposo se obtiene gracias a la accion de un resorte de giro en cuya posicion de reposo la plancha se encuentra en posicion aproximadamente vertical, siendo que este resorte de giro podra estar amortiguado para comodidad del usuario.This resting position is obtained thanks to the action of a rotating spring in whose resting position the plate is in an approximately vertical position, since this rotating spring may be damped for the user's comfort.

Mientras nadie la utiliza, la plancha esta en posicion de reposo, estando esa posicion forzada por el resorte de giro que es capaz de vencer el peso de la plancha y llevarla a la posicion inicial y mantenerla en dicha posicion, pero permitiendo que ceda ante la presion del usuario al sentarse sin que sea perceptible por el usuario una fuerza de expulsion.While no one uses it, the iron is in the rest position, being that position forced by the turning spring that is able to overcome the weight of the iron and take it to the initial position and keep it in that position, but allowing it to yield to the user pressure when sitting without a force of expulsion being perceived by the user.

Opcionalmente el recorrido de la plancha puede tener un tope.Optionally the path of the plate can have a stop.

Preferiblemente, el conjunto de plancha movil, primero y segundo juego de bujes, eje y el apoyo estara incluido en una carcasa semirrlgida de modo que el usuario no observara estos elementos mecanicos y se reducira el riesgo de pinzamientos.Preferably, the mobile plate assembly, first and second set of bushings, shaft and support will be included in a semi-rigid housing so that the user does not observe these mechanical elements and the risk of impingement will be reduced.

En la llnea de lo anterior, la parte inferior de la plancha puede incorporar un elemento elastico que cierra el espacio entre la plancha y la superficie de asiento reduciendo el riesgo de pinzamiento de un objeto o parte del cuerpo del usuario que se introduzca alll. Este elemento elastico unira generalmente la superficie de asiento a la plancha y podra ser un tejido de goma que, ademas, puede contribuir al retorno de la plancha a la posicion vertical, con lo que se obtienen dos ventajas con un unico elemento.In the above line, the lower part of the plate can incorporate an elastic element that closes the space between the plate and the seating surface reducing the risk of impingement of an object or part of the user's body that is introduced there. This elastic element will generally join the seating surface to the plate and could be a rubber fabric that, in addition, can contribute to the return of the plate to the vertical position, thus obtaining two advantages with a single element.

El conjunto que comprende la plancha, el primer y segundo juego de bujes, el eje y el apoyo es adecuado para asociarse a una silla, sillon o sofa entre otros entre los que pueden incluirse los asientos de automoviles, de mayor complejidad.The set comprising the iron, the first and second set of bushings, the axle and the support is suitable to be associated with a chair, armchair or sofa among others, among which car seats, of greater complexity, can be included.

Instalado el dispositivo de respaldo autoajustable, el usuario se sentara sobre una superficie de asiento, aproximadamente horizontal y ya existente y apoyara la espalda sobre el dispositivo de respaldo autoajustable.Once the self-adjusting backrest device is installed, the user will sit on a seat surface, approximately horizontal and already existing, and support the back on the self-adjusting backrest device.

Preferiblemente, la altura del eje sera regulable y se dispondra entre 12 y 33 cm sobre la superficie de asiento del usuario, y preferiblemente entre 18 y 27 cm.Preferably, the height of the shaft will be adjustable and will be arranged between 12 and 33 cm on the user's seating surface, and preferably between 18 and 27 cm.

Para el caso que el respaldo autoajustable no se apoye sobre un respaldo preexistente en la silla o sillon donde se va a ubicar, el respaldo autoajustable puede incorporar distintos elementos accesorios para quedar fijado y evitar que se desplace ante el peso del usuario.In the case that the self-adjusting backrest does not rest on a pre-existing backrest in the chair or chair where it is to be placed, the self-adjusting backrest can incorporate different accessory elements to be fixed and prevent it from moving before the user's weight.

Asl por ejemplo en una ejecucion posible el dispositivo puede incorporar unas piquetas adecuadas para clavarse en terreno blando tal como tierra o arena.Thus, for example, in a possible embodiment, the device may incorporate suitable picks for driving into soft ground such as dirt or sand.

En otra ejecucion posible puede incorporar unas patas antideslizantes para fijarlo sobre superficies lisas.In another possible embodiment, it can incorporate non-slip feet to fix it on smooth surfaces.

En una tercera ejecucion el dispositivo puede incorporar un faldon cuya funcion sera que el usuario fije el soporte por su propio peso lo cual sera de utilidad cuando, por ejemplo, el usuario desee leer en la cama y apoyarse en el dispositivo.In a third execution the device can incorporate a skirt whose function will be for the user to set the support by its own weight which will be useful when, for example, the user wishes to read in bed and lean on the device.

El dispositivo de asiento podra tener reposabrazos o cualquier otro elemento sin que se altere la naturaleza de la invention. Igualmente, la plancha podra tener curvatura, acolchado, flexibilidad, rigidez o cualquier otra medida para aumentar la comodidad del usuario.The seating device may have armrests or any other element without altering the nature of the invention. Likewise, the iron may have curvature, padding, flexibility, rigidity or any other measure to increase user comfort.
