Description

DESCRIPCIÓN DESCRIPTION
Reposacabezas para asientos de vehículos con airbag integrado. Headrest for vehicle seats with integrated airbag.
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La invención, tal y como el título de la presente memoria descriptiva establece, un reposacabezas para asientos de vehículos con airbag integrado se configura como una destacable novedad que dentro de las técnicas actuales aporta importantes ventajas de eficiencia. The invention, as the title of the present specification establishes, a headrest for vehicle seats with an integrated airbag is configured as a remarkable novelty that within current techniques provides significant efficiency advantages.
CAMPO DE APLICACIÓN DE LA INVENCION FIELD OF APPLICATION OF THE INVENTION
La presente invención, un reposacabezas para asientos de vehículos con airbag integrado, pertenece al sector automovilístico, y más concretamente a la fabricación de reposacabezas para asientos de automóviles. The present invention, a headrest for vehicle seats with an integrated airbag, belongs to the automotive sector, and more specifically to the manufacture of headrests for automobile seats.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Está demostrado que los reposacabezas tienen una gran importancia a la hora de asegurar la seguridad de los usuarios cuando estos tienen un accidente de coche. Es por lo tanto un elemento importante de seguridad pasiva. Headrests have been shown to be of great importance in ensuring the safety of users when they have a car accident. It is therefore an important element of passive security.
Actualmente consiguen que en un choque frontal con un obstáculo la cabeza impacte contra el reposacabezas, con lo que, si este está colocado a la distancia adecuada, ayuda a reducir las lesiones en las cervicales y lumbares. Sin embargo, en caso de accidente por alcance con otro vehículo la cabeza del usuario adquiere una aceleración grande, desplazando la cabeza hacia delante. En esos casos los reposacabezas actuales no evitan las lesiones. Y el airbag delantero que los vehículos tienen en el volante ayudan a mitigar las lesiones, pero no lo suficiente ya que están ubicados demasiado lejos. Con el objetivo de solucionar dicho problema, y ayudar a mejorar la seguridad de los usuarios frente a latigazos cervicales y lumbares se pretende desarrollar la presente invención, un reposacabezas para asientos de vehículos con airbag integrado. Ya que la bolsa de airbag se extiende hacia los dos lados de la cabeza del usuario, y desde la zona de la cabeza también substancialmente hacia delante evitando así los latigazos cervicales y hacía abajo linealmente con la columna vertebral para evitar latigazos y lesiones lumbares. Currently they manage that in a frontal collision with an obstacle the head impacts against the headrest, which, if this is placed at the appropriate distance, helps to reduce injuries to the cervical and lumbar spine. However, in the event of an accident with another vehicle, the user's head acquires a large acceleration, moving the head forward. In those cases the current headrests do not prevent injuries. AND The vehicle's front airbag on the steering wheel helps mitigate injuries, but not enough because they are located too far away. With the aim of solving this problem, and helping to improve the safety of users against whiplash and lumbar, it is intended to develop the present invention, a headrest for vehicle seats with integrated airbags. Since the airbag extends to both sides of the user's head, and from the head area also substantially forward thus avoiding whiplash and linearly down with the spine to avoid whiplash and lower back injury.
Por parte del solicitante no se tiene conocimiento de la existencia de ningún reposacabezas para asientos de vehículos con airbag integrado que presente características técnicas y funcionales iguales o semejantes a las descritas en esta memoria descriptiva, según se reivindica. The applicant is not aware of the existence of any headrest for vehicle seats with an integrated airbag that has the same or similar technical and functional characteristics as those described in this specification, as claimed.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Es objeto de la presente invención un reposacabezas para asientos de vehículos con airbag integrado, que aporta una innovación notable dentro de su campo de aplicación, estando los detalles caracterizadores que lo hacen posible convenientemente recogidos en las reivindicaciones finales que acompañan la presente descripción. The object of the present invention is a headrest for vehicle seats with an integrated airbag, which provides a remarkable innovation within its field of application, the characterizing details being made conveniently included in the final claims that accompany the present description.
El reposacabezas para asientos de vehículos con airbag integrado está formado por un reposacabezas tradicional para vehículos, donde el usuario apoya la cabeza. Dicho reposacabezas alberga en su interior un dispositivo de airbag, formado a su vez por un disparador de airbag y una bolsa de airbag. El reposacabezas comprende una tapa cubriendo una ventana dispuesta orientada hacia el espacio del asiento de tal manera que permite la salida de la bolsa de airbag. The headrest for vehicle seats with an integrated airbag is made up of a traditional headrest for vehicles, where the user supports the head. Said headrest houses inside an airbag device, formed in turn by an airbag trigger and an airbag bag. The headrest comprises a cover covering a window arranged oriented towards the seat space in such a way that it allows the exit of the airbag bag.
La bolsa de airbag en estado de inflado se extiende a ambos laterales desde la zona de la cabeza y substancialmente hacia delante, de tal manera que queda protegido el cuello y cabeza del usuario lateralmente y en la zona delantera y hacía abajo alineado a la columna para proteger y evitar lesiones lumbares. The airbag bag in the inflated state extends to both sides from the head area and substantially forward, in such a way that the user's neck and head are protected laterally and in the front area and downwards aligned to the column to protect and avoid lumbar injuries.
El reposacabezas se sujeta en los asientos de todo tipo de vehículos a motor, con las dos barras de reposacabezas, como es habitual. The headrest is attached to the seats of all types of motor vehicles, with the two headrest bars, as usual.
Con "dispositivo airbag" se quiere referir a los también llamados módulos de airbag que incluyen un disparador de airbag y una bolsa de airbag, con los componentes necesarios y conocidos para su funcionamiento como los componentes eléctricos y electrónicos que reciben la señal de disparo y activan éste mediante la iniciación de una reacción química que crea el gas que infla la bolsa. By "airbag device" we mean the so-called airbag modules that include an airbag trigger and an airbag bag, with the components necessary and known for their operation as the electrical and electronic components that receive the trigger signal and activate This by initiating a chemical reaction that creates the gas that inflates the bag.
Una ventaja es que se consigue una orientación de la bolsa de airbag que proporciona una protección óptima frente a impactos frontales, impactos laterales, y/o impactos por alcanzamientos traseros, que son los más graves y los que mayores lesiones provocan desde tetra-plegias hasta incluso la muerte, igual o superior que con cualquier otra configuración conocida, pero utilizando los mínimos componentes necesarios. Otra ventaja es que el dispositivo airbag está completamente integrado en el reposacabezas y, por tanto, no siendo necesario modificar nada más del habitáculo del vehículo, esto es, no es necesario modificar techo, paneles ni estructura. An advantage is that an orientation of the airbag is achieved, which provides optimal protection against frontal impacts, side impacts, and / or impacts from rear reaches, which are the most serious and the ones that cause the greatest injuries, from tetraplegia to even death, equal to or greater than with any other known configuration, but using the minimum necessary components. Another advantage is that the airbag device is completely integrated into the headrest and, therefore, it is not necessary to modify anything else in the vehicle interior, that is, it is not necessary to modify the roof, panels or structure.
Es por ello qué el reposacabezas para asientos de vehículos con airbag integrado de la presente invención aporta una innovación importante respecto a las técnicas tradicionales conocidas hasta ahora evitando las graves y serias lesiones cervicales y a veces irreversibles las lesiones lumbares y/o medulares. That is why the headrest for vehicle seats with integrated airbag of the present invention provides an important innovation with respect to the traditional techniques known up to now, avoiding serious and serious cervical injuries and sometimes irreversible lumbar and / or spinal injuries.
