Las figuras 1 a 4 muestran una realización del dispositivo de seguridad objeto de la presente invención, que queda integrado y toma la forma de un asiento de vehículo. El dispositivo, dispone de una estructura de asiento compuesta por una articulación (1) que conecta el dispositivo al chasis del vehículo, permitiendo el giro de una pieza de conexión (5) con respecto al chasis, y con ella, el resto del dispositivo, incluyendo las partes de respaldo y de asiento del asiento. La citada pieza de conexión (5) conecta la articulación de conexión al chasis (1) con otra articulación (2) que queda situada en el extremo opuesto al extremo del bastidor (6) del asiento más cercana al bastidor (7) de la parte de asiento. Esta articulación (2) permite que la parte de respaldo (10) varíe su altura relativa con respecto al extremo de la parte de asiento (9) más lejano a la parte de respaldo (10). Los elementos estructurales o bastidores (6), (7), correspondientes a las partes de asiento (9), y respaldo (10), respectivamente, están unidas por una articulación de conexión (3) que permite variar la inclinación de la parte de respaldo (10) con respecto a la parte de asiento (9). En el ejemplo mostrado, la estructura dispone, además de un elemento estructural o bastidor (8) para reposacabezas (11) unido al bastidor del respaldo (7) a través de una articulación (4). Si bien, por motivos de simplicidad de la explicación no se ha procedido a dibujarlos, todas las articulaciones mostradas (1), (2), (3), (4) disponen de medios automáticos que permiten ajustar su posición, lo que permite el movimiento de las mismas en caso de accidente, lo que requiere movimientos muy rápidos y una amortiguación baja. Sin embargo, dichas articulaciones serán utilizadas también para ajustar la posición del usuario del asiento en el vehículo, por lo que convendría también que las articulaciones puedan efectuar movimientos lentos. Por ello, podrá dotarse a los medios encargados de dotar de movimiento a las articulaciones, o a éstas mismas, de medios de amortiguación variable que permita ajustar la velocidad de movimiento de las articulaciones a los requerimientos de cada momento. Existen numerosos sistemas disponibles comercialmente que pueden realizar dicha función. Por ejemplo, podría incorporarse a la articulación un amortiguador viscoso, compuesto de discos de fricción y relleno de un fluido viscoso (sistema de amortiguación) que incluya también muelles de precarga encargados de fijar la posición del asiento. En caso de accidente, se inhabilitaría la acción del muelle de precarga entrando en acción el sistema de amortiguación. Por su parte, el accionamiento de los mecanismos que definen la posición de los componentes del asiento podría realizarse por medios electro-electrónicos, hidráulicos o mecánicos.Figures 1 to 4 show an embodiment of the safety device object of the present invention, which remains integrated and takes the form of a vehicle seat. The device, It has a seat structure composed of a joint (1) that connects the device to the vehicle chassis, allowing the rotation of a connecting piece (5) with respect to the chassis, and with her, the rest of the device, including the backup parts and of seat seat. The said connection piece (5) connects the linkage connection to the chassis (1) with another joint (2) which is located at the end opposite the end of the frame (6) of the seat closest to the frame (7) of the seat part. This joint (2) allows the backing part (10) to vary its relative height with respect to the end of the seat part (9) furthest from the backing part (10). Structural elements or racks (6), (7), corresponding to the seat parts (9), and backup (10), respectively, are joined by a connection joint (3) that allows varying the inclination of the backrest part (10) with respect to the seat part (9). In the example shown, the structure also has an element structural or frame (8) for headrest (11) attached to the frame of the backrest (7) through a joint (4). Yes well for Reasons for simplicity of explanation have not been proceeded to draw them, all the joints shown (1), (2), (3), (4) they have automatic means that allow adjusting their position, which allows their movement in the event of an accident, which It requires very fast movements and low damping. Without However, these joints will also be used to adjust the position of the seat user in the vehicle, so that it should also be possible for the joints to make slow movements For this reason, the means in charge may be provided to provide movement to the joints, or these, of variable damping means that allow speed adjustment of movement of the joints to the requirements of each moment. There are numerous commercially available systems that They can perform this function. For example, you could join the joint a viscous damper, composed of discs of friction and filling of a viscous fluid (damping system) which also includes preload springs responsible for fixing the seat position In the event of an accident, the action of the preload spring entering into action the system of damping For its part, the activation of the mechanisms that define the position of the seat components could be done by electro-electronic means, hydraulic or mechanical

También de manera preferente, se dispondrá de un cinturón de seguridad (12) para la zona inmediatamente superior a las rodillas del ocupante, con el fin de obtener aseguramiento de la posición de las rodillas del usuario, y cuyo fin será el de mantener las rodillas del usuario en contacto con la parte de asiento (9) en caso de accidente. El dispositivo también comprende una parte de respaldo (10) que igualmente podrá ser de tipo convencional, aunque también preferentemente presentará forma cóncava para una mayor protección del cuerpo del ocupante. De cara a minimizar la posibilidad de "escape" del cuerpo del ocupante en caso de accidente, la parte de respaldo (10) presentará un cinturón de seguridad (13), (13') para el torso del ocupante en forma de "X" con un broche central (14), (14'). Para prevenir posibles daños provocados por los cinturones de seguridad (12), (13), (13'), estos presentarán, preferentemente una sección transversal curva, por ejemplo cilíndrica.The device is completed with a part of seat (9), which may be of the conventional or concave type, as shown in the figures. Also preferably, it you will have a seat belt (12) for the area immediately above the occupant's knees, in order to obtain assurance of the user's knee position, and whose purpose will be to keep the user's knees in contact with the seat part (9) in case of an accident. The device it also comprises a backing part (10) that may also be of the conventional type, but also preferably present concave shape for greater protection of the occupant's body. From in order to minimize the possibility of "escape" from the body of the occupant in case of accident, the backup part (10) will present a seat belt (13), (13 ') for the torso of the occupant in "X" shape with a central clasp (14), (14 ').

En las figuras 5 y 6 se muestran dos posibles realizaciones del procedimiento objeto de la presente invención en caso de choque frontal o vuelco y en caso de choque trasero o alcanzamiento, respectivamente.Figures 5 and 6 show two possible embodiments of the process object of the present invention in case of frontal crash or overturning and in case of rear shock or reach, respectively.
En caso de choque frontal o vuelco (ver figura 5), el sistema de detección emite la señal o señales correspondientes y, en función de las mismas, el dispositivo de control ordena disminuir la altura relativa del extremo de la parte del asiento (9) más próxima a la parte de respaldo (10) con respecto al extremo opuesto de la parte de asiento. Esto puede hacerse mediante giro de la articulación correspondiente (2) del dispositivo antes descrito.In case of frontal collision or overturning (see figure 5), the detection system emits the signal or signals corresponding and, depending on them, the device control orders to decrease the relative height of the end of the part of the seat (9) closest to the backrest part (10) with respect to to the opposite end of the seat part. This can be done by rotating the corresponding joint (2) of the device described above
Luego se procede a hacer girar la parte de respaldo (10) con respecto a la parte de asiento (9) acercando dichas partes entre sí. Esto se puede hacer mediante el giro correspondiente de la articulación (3) que une ambas partes.Then we proceed to rotate the part of backrest (10) with respect to the seat part (9) approaching those parts with each other. This can be done by turning corresponding joint (3) that joins both parts.
En el caso preferente en el que el dispositivo comprenda un reposacabezas (11) se procede posteriormente a hacer girar el reposacabezas (11) en dirección hacia la zona de respaldo (10) y la zona de asiento (9), mediante el giro correspondiente de la articulación (4).In the preferred case in which the device understand a headrest (11) then proceed to make turn the head restraint (11) towards the backrest area (10) and the seating area (9), by corresponding rotation of the joint (4).
En el caso de que las articulaciones (1), (2), (3), (4) presente una amortiguación variable, cuando recibe una señal de colisión, el dispositivo de control puede proceder a modificar la amortiguación de las articulaciones para obtener una respuesta adecuadamente rápida y eficaz.In the event that the joints (1), (2), (3), (4) present a variable damping, when you receive a collision signal, the control device can proceed to modify the cushioning of the joints to obtain a Properly fast and effective response.
De esta manera, el ocupante del asiento asume posición fetal y se evitan golpes con partes del vehículo, a la vez que se evita el latigazo y el desplazamiento del cuerpo del ocupante.In this way, the seat occupant assumes fetal position and bumps with parts of the vehicle are avoided at the same time Whiplash and body displacement are avoided occupant.
En el caso de choque trasero (ver figura 6) el sistema de detección emite la señal o señales correspondientes y, en función de las mismas, el dispositivo de control ordena hacer que la parte de respaldo (10) aumente el ángulo formado con la parte de asiento (9), de tal manera que ambas partes tiendan a alinearse. Esto puede realizarse mediante el giro correspondiente de la articulación (3) que une ambas partes.In the case of rear shock (see figure 6) the detection system emits the corresponding signal or signals and, depending on them, the control device orders to make the backing part (10) increases the angle formed with the part of seat (9), so that both sides tend to align. This can be done by corresponding rotation of the joint (3) that joins both parts.
Luego se procede a hacer que la totalidad del asiento describa un movimiento general hacia detrás, preferentemente mediante un giro alrededor de la articulación (1) de conexión al chasis del vehículo.Then we proceed to make the entire seat describe a general backward movement, preferably by turning around the joint (1) connecting to the vehicle chassis
Por último, en el caso de que el dispositivo disponga de reposacabezas (11), se procederá a hacer girar el reposacabezas (11) alejándolo de la zona de respaldo (10) y de asiento (9).Finally, in the case that the device have a headrest (11), proceed to rotate the headrest (11) away from the backrest area (10) and from seat (9).
De esta manera se evita el latigazo producido por la colisión y posibles traumatismos con partes frontales del vehículo.This avoids the whiplash produced for the collision and possible trauma with frontal parts of the vehicle.
Preferentemente, las diferentes fases del procedimiento descrito se producirán en el orden indicado.Preferably, the different phases of the described procedure will occur in the order indicated.
En el caso preferente en el que el dispositivo comprenda un reposacabezas (11) se procede posteriormente a hacer girar el reposacabezas (11) en dirección hacia la zona de respaldo (10) y la zona de asiento (9).In the preferred case in which the device understand a headrest (11) then proceed to make turn the head restraint (11) towards the backrest area (10) and the seating area (9).
Una vez parado el vehículo, el asiento, una vez realizada su función de protección y absorción del impacto, podrá volver a su posición inicial para dejar espacio a los ocupantes para que puedan salir por su propio pie o puedan ser rescatados con facilidad.Once the vehicle is stopped, the seat, once performed its function of protection and absorption of impact, may return to its initial position to leave room for occupants to that can leave on their own foot or can be rescued with ease.
En general, todo lo que no afecte, altere, cambie o modifique la esencia del dispositivo descrito, quedará comprendido dentro de la presente invención.In general, everything that does not affect, alter, change or modify the essence of the described device, it will remain comprised within the present invention.
