Abstract

The invention relates to a device responsive to impacts and overturning, placed on the "floor" of a vehicle, and capable of triggering a signal on the basis of a sudden deceleration or an overturning. This device consists of a truncated-conical casing (1) with vertical axis and closed at the top and in which a sphere (4), whose weight is sufficient to keep the lever (6) of the microcontact (5) in the bottom position by way of the spring (7), can dance freely. The movement of the sphere (4) caused by an impact takes place vertically by reaction on the conical wall, thus freeing the microcontact. In the case of overturning, the sphere moves under gravity, thus freeing the microcontact. This device according to the invention is particularly intended for any transport vehicle, and enables signals of any kind to be automatically triggered in the event of an accident. <IMAGE>

Le brevet FR2.214.954 fait état d'un dispositif fonction­nant par choc brutal ou retournement d'un véhicule pour annuler les principales causes d'incendie au cours d'acci­dent, en coupant automatiquement le courant sur le fil principal de l'équipment.Patent FR2.214.954 describes a device operating by brutal shock or overturning of a vehicle to cancel the main causes of fire during an accident, by automatically cutting the current on the main wire of the equipment.

Bien que ces différents dispositifs aient été mis au point, il reste de nombreux problèmes à résoudre.Although these various devices have been developed, there are still many problems to be solved.

L'un de ces problèmes concerne la signalisation d'un véhicule accidenté qui peut être hors de portée de vue, de jour ou de nuit, bien que très proche d'un axe de circulation.One of these problems concerns the signaling of an accident vehicle which can be out of sight, day or night, although very close to a traffic lane.

Un autre de ces problèmes concerne l'incapacité temporaire ou permanente du conducteur ou d'un passager à se dégager d'un véhicule accidenté, hors de vue, pour chercher secoursAnother of these problems concerns the temporary or permanent inability of the driver or passenger to get out of a crashed vehicle, out of sight, to seek help.

Les dispositifs dit coupe-circuit ou coupe-batterie interdisent l'alimentation électrique de signaux.The so-called circuit breaker or battery cut-out devices prohibit the power supply of signals.

Aucune norme en la matière ne règlemente de tels disposi­tifs.No standard in the matter regulates such devices.

Le dispositif selon l'invention a pour but de résoudre simultanément tous ces problèmes.The aim of the device according to the invention is to simultaneously solve all these problems.

Le présent dispositif prévoit à cet effet un procédé permettant, à partir d'un choc ou d'un changement de posi­tion important du véhicule par rapport à la gravitation (retournement ou renversement), d'actionner un ou plusieurs relais de commande d'appareils de signalisation : sonores (continu,itératifs ou alternés) électronique (radio, radio-­téléphone ou alarme) lumineux (clignotants, phares) de sécurité (coupe-batterie, extincteur) ou tous autres appa­reils internes ou externes au véhicule, permettant ainsi d'attirer l'attention sur sa présence de jour comme de nuit. Dans les travaux de recherche entrepris par le titu­laire, dans le but de mettre au point un dispositif sécuri­sant et efficace, il a été pris en compte les seuils minima de paramètres (déccélération et inclinaison) compatibles avec l'usage normal qu'il est fait de tout véhicule, transportant des passagers, sans déclenchement intempestif du dispositif.The present device provides for this purpose a method allowing, from an impact or a significant change in position of the vehicle relative to gravitation (overturning or overturning), to actuate one or more device control relays signaling: audible (continuous, iterative or alternating) electronic (radio, radio-telephone or alarm) luminous (indicators, headlights) of safety (battery switch, fire extinguisher) or any other internal or external devices to the vehicle, thus draw attention to its presence during the day as night. In the research work undertaken by the holder, with the aim of developing a secure and efficient device, the minimum thresholds of parameters (deceleration and tilt) compatible with the normal use have been taken into account. of any vehicle carrying passengers, without inadvertent triggering of the device.

A cet effet, l'invention prévoit un dispositif réagissant selon des lois physiques et mécaniques connues, à partir de caractéristiques mécaniques et dimensionnelles déterminées en fonction des valeurs de réaction au choc ou angle de renversement que le constructeur veut assurer.To this end, the invention provides a device reacting according to known physical and mechanical laws, from mechanical and dimensional characteristics determined as a function of the impact reaction values or tilt angle that the manufacturer wants to ensure.

Ainsi le dispositif se compose de :Thus the device consists of:

Un cône tronqué, creux, renversé et fixé perpendiculaire­ment au "plancher" du véhicule, dans lequel repose une sphère métallique, pesante. Le segment inférieur de cette sphère, par l'intermédiaire d'un ressort, maintient le levier de commande d'un micro-contact en position de coupure (fig 1)A truncated, hollow cone, inverted and fixed perpendicular to the "floor" of the vehicle, in which rests a heavy metallic sphere. The lower segment of this sphere, by means of a spring, keeps the control lever of a microswitch in the cut-off position (fig 1)

Lors d'une collision, quel qu'en soit le sens (importance du cône) l'inertie de la sphère, au contact de la paroi inclinée du cône la propulse dans la partie haute du dispo­sitif, libérant le ressort et donc le levier du micro-­contact (fig 2). Ce micro-contact "ferme" un circuit pri­maire qui alimente l'excitation d'un relais "pilote". Ce relais assure son auto-alimentation en même temps qu'il commande un ou plusieurs relais secondaires. Ces relais secondaires commandent eux mêmes des appareils de signali­sation : sonore (continus, itératifs, ou alternés), lumineux (clignotants, faisceaux), électroniques (radio, radio-téléphone ou alarme), de sécurité (coupe-batterie, extincteur) ou tout appareil dont on voudra assurer l'auto­maticité.During a collision, whatever the direction (size of the cone) the inertia of the sphere, in contact with the inclined wall of the cone propels it into the upper part of the device, releasing the spring and therefore the lever micro-contact (fig 2). This micro-contact "closes" a primary circuit which feeds the excitation of a "pilot" relay. This relay ensures its self-supply at the same time as it controls one or more secondary relays. These secondary relays control signaling devices themselves: audible (continuous, iterative, or alternating), luminous (flashing, beams), electronic (radio, radio-telephone or alarm), security (battery switch, fire extinguisher) or any device that we want to ensure automaticity.

Dans le cas ou, même sans subir un choc majeur, le véhicule s'incline ou se renverse, la sphère quitte son assise sollicitée par la pesanteur, et met le dispositif en alerte (fig 3).In the case where, even without undergoing a major shock, the vehicle tilts or overturns, the sphere leaves its seat urged by gravity, and puts the device on alert (fig 3).

Si pour en assurer le fonctionnement automatique, on a assujetti l'appareil à la clé de contact (par exemple) un interrupteur supplémentaire est nécessaire : la masselotte déplacée ne peut plus assurer la coupure du circuit par le micro-contact.If to ensure automatic operation, the device has been subjected to the ignition key (for example) an additional switch is necessary: the moved shoe can no longer ensure the circuit is cut by the micro-contact.

La batterie d'accus du véhicule peut-être détruite lors de la collision, il est prudent d'alimenter l'appareillage par une batterie sèche (maintenue en charge par les circuits du bord). Batterie que l'on aura soin de grouper avec les autres composants au "plancher", près du centre de gravité du véhicule pour en assurer une protection plus facile et plus efficace (un "gueulard" peut se loger sous le "plancher", que l'on protègera des projections de la route). Moins on offrira de surface vulnérable, plus le dispositif sera fiable.The vehicle's battery may be destroyed during the collision, it is prudent to supply the device with a dry battery (kept charged by the on-board circuits). Battery that we will take care to group with the other components at the "floor", near the center of gravity of the vehicle to ensure easier and more effective protection (a "shout" can be housed under the "floor", that protect from road projections). The less vulnerable surface area, the more reliable the device.

Le centre de gravité du véhicule est à préférer : les réactions y sont pondérées. Lors d'un accident, c'est souvent la partie la moins sinistrée.The center of gravity of the vehicle is to be preferred: the reactions are weighted there. In an accident, it is often the least affected part.

Le diamètre de la sphère est supérieur à l'ouverture inférieure du tronc de cone.
- Un micro-contact (5) ou tout autre appareil à ouverture de circuit équipé d'un levier (6).

- A micro-contact (5) or any other device with circuit opening equipped with a lever (6).
- A compression spring (7) integral with the lever and of frustoconical shape forms, in its largest larger diameter, the seat of the sphere in normal position.
