Abstract

Device making it possible to improve a system of the individual-protection type serving to protect an individual from attack by fire or any other forms of attack or contamination requiring such a device. The latter is characterised in that the inflatable structure is held in position by an inflatable spider-like contrivance sandwiched between the walls of the inflatable structure of this device. The outer and inner walls of this envelope are fastened together by means of stitching made between each branch of this spider-like contrivance.

Description

La présente invention concerne une amélioration concernant un dispositif permettant de protéger un individu contre une agression par le feu dans un incendie et de toutes autres agression polluante,naturelles ou artificielles.The present invention relates to an improvement relating to a device making it possible to protect an individual against an attack by fire in a fire and from any other polluting attack, natural or artificial.

Le dispositif existant actuellement étant caractérisé par le fait qu'il se porte dans le dos de l'individu,à l'aide d'une ceinture ou bretelle,plié,de faible encombrement,ne génant pas son évolution.L'élément principal de ce dispositif existant,étant constitué par une enveloppe gonflable en forme de parapluie Figl que cette enveloppe est fabriquée en tissus anti-feu résistant à haute température,qu'en cas de necessité,l'individu actionne une bombe de gaz(4)Fig3comprimé, laquelle gonflera instantannément l'enveloppe.L'amélioration principale de ce dispositif étant caractérisé par le fait que la structure gonflable est maintenue en position par une araignée gonflable(l0)Fig4,prise en sandwich entre les parois externe et interne(l)Fig4 de l'enveloppe,que ses parois sont solidarisées entre elles pa une couture(ll)Fig5 faite entre chaque branche de l'araignée.Cette amélioration Fig4consistant à modifier la structure interne de l'enveloppe gonflable.L'avantage de cette modification portant essentiellement à résoudre les problémes existant sur le dispositif actuel:
l-Résoudre le probléme d'étanchéité à l'air de la paroi externe soumise à une trés haute température.The existing device currently being characterized by the fact that it is worn on the back of the individual, using a belt or suspender, folded, of compact size, not interfering with its evolution. The main element of this existing device, being constituted by an inflatable envelope in the shape of an umbrella Figl that this envelope is made of fire-resistant fabrics resistant to high temperature, that if necessary, the individual actuates a gas bomb (4) Fig3compressé, which will instantly inflate the envelope. The main improvement of this device being characterized by the fact that the inflatable structure is held in position by an inflatable spider (l0) Fig4, sandwiched between the external and internal walls (l) Fig4 of the envelope, that its walls are secured to each other pa a seam (ll) Fig5 made between each branch of the spider.This improvement Fig4consistent in modifying the internal structure of the inflatable envelope. The advantage of c ette modification essentially to solve the problems existing on the current device:
l-Solve the air tightness problem of the external wall subjected to a very high temperature.

2-Diminuer le volume d'air necessaire pour le gonflage de la stucture. 2-Decrease the volume of air necessary for the inflation of the structure.

3-Simplifier sa fabrication. 3-Simplify its manufacture.

La bombe de gaz comprimé(4) Fig3 pouvant être intégrée au dispositif.L'amélioration actuelle permet maintenant d'utiliser pour la fabrication de l'enveloppe, un matériau uniquement résistant à haute température et pas necessairement étanche à l'air,elle protége ainsi l'araignée gonflable(l0)Fig4 servant de structure à cette derniére.Le volume d'air étant réduit par le fait que l'air sous pression se trouve uniquement dans l'araignée gonflable;alors que dans le systéme actue l'air sous pression est necessaire dans toute la structure.The compressed gas bomb (4) Fig3 can be integrated into the device. The current improvement now makes it possible to use for the manufacture of the envelope, a material only resistant to high temperature and not necessarily airtight, it protects thus the inflatable spider (l0) Fig4 serving as a structure for the latter.The air volume being reduced by the fact that the pressurized air is only in the inflatable spider; while in the system actuates the air under pressure is required throughout the structure.

Du fait de l'élimination des problémes d'étanchéité de ltenveloppe,l'amélioration actuelle simplifie la fabrication de ce dispositif.Due to the elimination of the sealing problems of the envelope, the current improvement simplifies the manufacture of this device.

Afin de rendre plus étanche le contact de l'enveloppe avec le sol,il est prévu de fixer sur tout le pourtour en contact avec le sol,un boudin souple(l2)Fig5 de même matiére que I'enveloppe,afin de compenser les inégalités de la surface du terrain.Des poignées(8)Figl fixées à l'intérieur de la paroiinterne,servant à plaquer plus fortement l'enveloppe gonflée plus fortement sur le sol,améliorant d'autant la sécurité.In order to make the contact of the envelope with the ground more watertight, it is planned to fix over the entire periphery in contact with the ground, a flexible tube (l2) Fig5 of the same material as the envelope, in order to compensate for the inequalities of the surface of the ground. Handles (8) Figl fixed inside the internal wall, serving to press more strongly the inflated envelope more strongly on the ground, thereby improving safety.

Claims

l) Individual portable device intended to protect an individual against an attack by flames in a fire, or any other attack or pollution requiring such a device of the type comprising an inflatable envelope (l), which once folded and in the waiting position can be worn with a belt or strap on the back of the individual.That this device inflates instantly by a gas bomb that can be integrated into the device.

That this envelope once inflated, takes the form of an umbrella under which the individual will be sheltered, characterized by the fact that the external and internal walls of the inflatable envelope, are held in position by an inflatable spider ( l0) with several branches, sandwiched between these two walls

Fig4.These same walls being joined together by a seam made between each of the branches of the spider (10), represented by fig5 (11).

2) Device according to claiml characterized in that it comprises over the entire periphery in contact with the ground, a flexible tube (l2) to strengthen the tightness of the envelope with the ground.

3) Device according to claiml characterized in that it has inside the envelope of the handles (8) for pressing the latter more strongly with the ground.
