An accident in adverse climatic conditions?


The invention relates to a system for signalling and locating vehicles involved in accidents, stopped vehicles and vehicles with mechanical problems in daytime and night-time conditions as well as in adverse weather conditions. According to the invention, the occupants of the vehicle can raise...

Incorporada en un SPOLDIER ubicado en la parte superior de la luneta trasera del vehículo, donde generalmente viene instalada la tercera luz de STOP, la baliza se presenta plegada y con una carga suficiente de gas y/o aire comprimido (cartuchos sistema AIRBAGS), conectada a un dispositivo de des aceleración (con efecto retardado) y una válvula de cierre. Receptor de control remoto para activación manual.

Incluye LEDS con alimentación independiente.


En caso de accidente y/o desperfecto del vehículo, la baliza puede ser disparada:


a) En forma manual, activándola desde el interior del vehículo mediante un dispositivo de control remoto.

b) En forma automática, por razón del impacto y por efecto del sistema de des aceleración. En este caso, debe ser retardada la activación y cuando el vehículo se encuentra detenido, se activa.

En ambas circunstancias, la BALIZA FLOTANTE permite señalizar y visualizar a distancia el vehículo, para evitar que sea embestido.




Dispositivo únicamente como accesorio de compra libre. Para ser utilizado en caso de emergencia y en modo MANUAL. Este dispositivo –con iguales características que el anterior- se presenta en un sobre (de diversos materiales: Cuero, caucho, plástico) que incluye los elementos de BALIZA PLEGADA, cartuchos de gas inerte y/o aire comprimido (Sistema AIRBAGS), LEDS con alimentación autónoma (baterías), válvula de cierre.

El accesorio, que puede ser transportado debajo del asiento, en la guantera y/o en la gaveta de la puerta y –en caso de necesidad- se coloca en el techo del vehículo, y al solo contacto con éste, se dispara formando (desplegando) un cono de tres puntas (figura geométrica) de 100cms de altura, visible desde cualquier ángulo. Incorpora un sistema de imanes como método de adhesión al techo.

El principio de funcionamiento del equipo es el mismo que utilizan las carpas (que se arman solas) de camping. El disparo –la presión del gas inerte- hace que la figura geométrica se arme sobre el techo.


NOTA Para tener en cuenta

En los casos descritos, ambos están patentados en USA y ESP.

Lo que hay patentado es un sistema de señalización en altura. Ello implica que la baliza flotante pueda tomar diversas formas, tamaños y posiciones de ubicación, conforme los requerimientos del mercado y/o el uso.


Ambos equipos son TOTALMENTE INDEPENDIENTES de las instalaciones de fábrica de los coches. Se pueden comprar COMO ACCESORIO, siendo para el caso AUTOMÁTICO MANUAL, necesaria una instalación por parte de un técnico y/o mecánico.

Description of the beacon

The system in question is for giving a signal and making it possible to locate vehicles which have had accidents, have been stopped or suffered mechanical failures while travelling by day or night in adverse climatic conditions.  

The system consists of a box (Chassis) with form shark fin, with a lid, of strong material (carbon fiber) , joined together by means of a hinge, which inside has a container of helium, hydrogen, or other gas with a specific weight lower than air, joined at one end by a tube for the exit of fluid gas and a non-returning valve which has a rapid manual opening device and a system in the entrance of an inflatable fluorescent aerostatic body which is empty and folded in a non-operative condition inside the box.

When the vehicle receives an impact, the system sets off via the inertia action of a sensor device activated according to a deceleration power which is over 3G, and is powered by a source of energy composed of batteries or accumulators belonging to an autonomous electricity circuit for the said vehicle, and this would be joined to an electrical conductor cable ending with an associated connector with a luminous blinker, with an electronic flash, to a light sensor activated in the dark and miniature localiser via satellite to follow up the global positioning system (GPS).

The advantage of the system is that it authorises the occupants to send a warning without getting out of the vehicle.

On the other hand, the development of this system comprises three different types of equipment, with the same final application.

First:  A system – automatic and manual – incorporated into cars and linked (for example) to the sensors of airbags, which at the moment of impact and/or absent-mindedness and/or loss of consciousness of the driver, would be set off and activate according to the description.

This equipment can only be incorporated when the vehicle is originally manufactured, i.e. on the production line, whereby we understand that to develop this prototype would necessarily need the participation of automobile industries with their corresponding acceptance.  At the same time, it may also be operated manually with a switch located inside the vehicles.

Second.  A manual system which can be incorporated in cars under the mode “accessories”, which would be independent, in an eye catching package, of a small size so that it could be put under the seat, for example, together with the fluorescent jacket, in the door pocket, the glove compartment, etc.

This equipment is very simple and does not go off automatically with the 3G decelerating/firing device and can be activated “only” at the command of the driver and/or passenger.  It does not work in the case of an impact, except if the driver chooses to activate it.

Third: This third option we believe to be the most effective to apply in our development.  It is a semi-automatic equipment which is incorporated as an accessory and is installed in the car in a visible and protected place.  If one looks at the case of new BMW cars, the antennas placed at the top part of the back windscreen can give us an idea of the location and even of the shape that this could have (there may be more than one per car).

This device is for manual use (from inside the car) and also for automatic use by the deceleration of over 3G, with a sensor specially incorporated for the purpose. 

Although it may not fulfil all the requirements to be considered automatic, it is a good solution for the application of the invention.  It is an accessory which may be marketed independently from the car itself, which only requires the corresponding homologations, without having to be subjected to approvals by the automobile industry. 

In accordance with the current situation of the patent and the registration process on behalf of the Spanish and worldwide organisms, these devices fulfil the necessary requirements from a legal standpoint.
