Abstract

The air cushion (6) is fixed to the ceiling (5) of the house which is to be protected. The cushion is connected to an air tank (1) through piping (4). An activating sensor (3) placed on this piping , near to the tank, opens the tank valve (2) in the case of earthquake. This results in rapid inflation of the air cushion. The activating sensor consists of a metallic mass placed on a support rod. The mass is connected to a valve lever by a cable.

Description

DESCRIPTION
La présente invention concerne un système permettant de préserver les vies humaines en cas de seisme dans les habitations de 1à 3 étages.DESCRIPTION
The present invention relates to a system for preserving human lives in the event of an earthquake in dwellings of 1 to 3 floors.

PRINCIPE
Lors du seisme, un coussin d'air préalablement fixé au plafond de la pièce à protéger (coussin d'air vide et plat), se gonfle en un temps très court (de 5 à 10 secondes), s'interposant entre les occupants de la pièce et les débrits divers en provenance du plafond.PRINCIPLE
During the earthquake, an air cushion previously fixed to the ceiling of the room to be protected (empty and flat air cushion), inflates in a very short time (5 to 10 seconds), interposing between the occupants of the room and various debris from the ceiling.

ELEMENTS CARACTERISTIQUES DU SYSTEME - Le coussin d'air (6/fig.1)
Fixé au plafond de la pièce à protéger, il est fabriqué en un tissu très résistant, plastifié et étanche. Il est retenu au plafond par des fixations appropriées (11/fig.5). D'autres fixations internes (12/fig.5) lui permettent de rester plaquer au plafond (les fixations (12/fig.5) peuvent être réutilisées autant de fois que nécessaire, type adhésif).CHARACTERISTIC ELEMENTS OF THE SYSTEM - The air cushion (6 / fig.1)
Attached to the ceiling of the room to be protected, it is made of a very resistant, plasticized and waterproof fabric. It is retained on the ceiling by appropriate fixings (11 / fig.5). Other internal fixings (12 / fig.5) allow it to remain flat on the ceiling (the fixings (12 / fig.5) can be reused as many times as necessary, adhesive type).

Le coussin d'air est également équipé d'un clapet anti-retour -(13/fig.5), évitant en cas de rupture des canalisations (4/fiv.1) que le coussin ne se dégonfle. The air cushion is also equipped with a non-return valve - (13 / fig.5), preventing the airbag from deflating in the event of a break in the pipes (4 / fiv.1).

- La réserve d'air comprimé
Enterrée approximité de l'habitation, elle est fabriquée à partir d'un réservoir en plastique (rigide et étanche) entouré d'une importante épaisseur de béton armé (1/fig.1). - The compressed air reserve
Buried roughly in the house, it is made from a plastic tank (rigid and waterproof) surrounded by a thick layer of reinforced concrete (1 / fig.1).

- Capteur actionneur(3/fig.1)
Situé approximité de la réserve d'air, le capteur actionneur est également enterré (un regard permet d'y accéder le cas échéant). Il est constitué d'une masse métallique (9/fig.3) reliée au bras de levier (7/fig.3) de la vanne d'isolement (2/fig.3) à l'aide d'un cable (8/fig.3).- Actuator sensor (3 / fig. 1)
Located close to the air reserve, the actuator sensor is also buried (a manhole allows access if necessary). It consists of a metallic mass (9 / fig.3) connected to the lever arm (7 / fig.3) of the isolation valve (2 / fig.3) using a cable (8 /fig.3).

Cette masse est placée sur une tige support (10/fig.3) en équilibre stable mais précaire. En cas de séisme, la masse tombe et ouvre la vanne. This mass is placed on a support rod (10 / fig.3) in stable but precarious equilibrium. In the event of an earthquake, the mass falls and opens the valve.

La sensibilité de ce capteur est obtenue en agissant sur les dimensions de la masse et de la tige. The sensitivity of this sensor is obtained by acting on the dimensions of the mass and the rod.

- Canalisations (4/fig.1)
Elles relient la réserve d'air au coussin d'air. Ces canalisations doivent avoir un diamètre suffisant, en effet le temps de gonflage en dépend. Leur trajet ainsi que leurs fixations sont conçus de manière à éviter leur destruction en cas de séisme. - Pipes (4 / fig.1)
They connect the air reserve to the air cushion. These pipes must have a sufficient diameter, in fact the inflation time depends on it. Their path and their fixings are designed to prevent their destruction in the event of an earthquake.
