Abstract

The invention relates to a removable device making it possible to cut, alone, quickly, and effortlessly, a jammed seat belt. It consists of a casing formed of two parts 1, 2 articulated together, and of a cutting unit moving in an open window on the top of the device. The cutting unit is formed of a pusher 4, of a cutting blade placed in a bevel 6, of two pressure studs 5 for holding the belt during cutting, and of a guide groove 9 placed below the pusher 4. The device clamps the belt, without pinching it, by virtue of felt or rubber strips 8 placed at the top and bottom of the two entry points 17. The device according to the invention is particularly intended for cutting jammed car seat belts.

Description

La présente invention concerne un dispositif pour couper une ceinture de sécurité bloquée et permettre à une personne de se dégager rapidement. The present invention relates to a device for cutting a locked seat belt and allowing a person to quickly get out.

En effet, souvent en cas d'accident de la route les ceintures de sécurité se bloquent ct cela est la cause d'une aggravation dec conséquences de l'accident et/ou de génération d'état de choc, de panique. In fact, often in the event of a road accident, the seat belts are locked and this is the cause of a worsening of consequences of the accident and / or generation of shock, panic.

Généralement pour se dégager d'une ceinture bloquée on utilise un couteau ou des ciseaux. Generally to free yourself from a blocked belt, use a knife or scissors.

En dehors d'une prévoyance particulière il est rare d'avoir en automobile des ciseaux ou un couteau à disposition. Le cas échéant, en étant bloqué par une ceinture de sécurité, il deviens presque impossible d'accéder à la boite à gants surtout en cas de blessures ou d'état de choc. Apart from a special provision, it is rare to have in the car scissors or a knife available. If necessary, by being locked by a seat belt, it becomes almost impossible to access the glove compartment, especially in the event of injuries or shock.

La présente invention se place sur la ceinture de sécurité en l'enserrant sans la pincer1 pour permettre son déplacement aisé par simple coulissement. Adapté à la ceinture, le dispositif sera toujours opérationnel en cas de besoin. Le coulissement du système permet de ne pas géner le rembobinage de la ceinture en temps normal. Il permet également à chacun de le glisser au niveau qui lui semble le plus adéquat. Le systéme se placera de préférence sur la portion de ceinture comprise entre le thorax et la hanche. Le dispositif étant amovible il pourra être utilisé pour dégager une personne bloquée dans un autre véhicule en quelques secondes. The present invention is placed on the seat belt by enclosing it without pinching it to allow its easy movement by simple sliding. Adapted to the belt, the device will always be operational when necessary. The sliding of the system does not interfere with the rewinding of the belt in normal times. It also allows everyone to drag it to the level that seems most suitable. The system will preferably be placed on the portion of belt between the thorax and the hip. The device being removable it can be used to free a person trapped in another vehicle in a few seconds.

Le dispositif est formé d'un boitier recourbé à ses extrémités pour ne pas géner l'utilisateur. Il est formé de deux parties (1.2) avec des arêtes et coins arrondis reliées entre elles par des charnières (IO.II) placées à l'avant du bloc de coupe (Fig.4) pour éviter que la lame tranchante (6) ne soit mise à jour en position d'ouverture du dispositif, et par une languette de fermeture (12) sur la partie supérieure (1) qui se place dans une encoche (13) de la partie inférieure (2). Le dispositif peut être enlevé et remis à volonté. The device consists of a box curved at its ends so as not to interfere with the user. It consists of two parts (1.2) with rounded edges and corners connected to each other by hinges (IO.II) placed at the front of the cutting block (Fig. 4) to prevent the sharp blade (6) from or updated in the open position of the device, and by a closing tab (12) on the upper part (1) which is placed in a notch (13) in the lower part (2). The device can be removed and returned at will.

Le bloc de coupe (Fig.4) comprend une partie poussoir (4) en relief par rapport au boitier1 une partie rétrécie servant de rainure-guide et de glissiére (9), une lame tranchante placée en biseau (6), deux ergots de pression (5o5r) placés de chaque côtés de la-lame tranchante (6) et appuyant sur la ceinture pour faciliter la coupe.  The cutting block (Fig. 4) comprises a pusher part (4) in relief with respect to the housing 1 a narrowed part serving as a guide groove and slide (9), a cutting blade placed in a bevel (6), two lugs of pressure (5o5r) placed on each side of the cutting blade (6) and pressing on the belt to facilitate cutting.

La partie inférieure du boitier (2) comprend une partie plus épaisse qui détient la partie femelle de la charnière (10), une encoche en son dessus (16) ct une encoche dans sa largeur- côté interne (15). Dans sa longueur et en son centre une fente étroite (7) est réservée pour recevoir le bas de la lame (6), lui servir de guide et de maintien de force. A l'autre extrémité se trouve l'encoche (13) prévue pour recevoir la languette de fermeture (12) de la partie supérieure. A cette extrémité il y a une plus grande épaisseur que sur la longueur. The lower part of the housing (2) comprises a thicker part which holds the female part of the hinge (10), a notch on its top (16) and a notch in its width - internal side (15). In its length and in its center a narrow slot (7) is reserved for receiving the bottom of the blade (6), serving as a guide and holding force. At the other end is the notch (13) intended to receive the closing tab (12) of the upper part. At this end there is a greater thickness than on the length.

La partie supérieure du boitier (1) comprend une longue ouverture (14), les parties mâles des charnières (11) et un ergot allongé de fermeture (12). The upper part of the housing (1) comprises a long opening (14), the male parts of the hinges (11) and an elongated closing lug (12).

Au niveau des entrées du boitier (t7) prévues pour le passage de la ceinture de sécurité sont collées des bandes de feutrine ou de caoutchouc (8) pour assurer le maintien du dispositif sur la ceinture sans en interdir le déplacement. At the inputs of the housing (t7) provided for the passage of the seat belt are glued strips of felt or rubber (8) to ensure the maintenance of the device on the belt without prohibiting movement.

Le bcitier sera fabriqué dans un plastique ferme maisMrigide résistant à la chaleur d'un chaud soleil estival. La fabrication des pièces se fera par injection de plastique. Le plastique utilisé pour le bloc de coupe (Fig. 4) sera choisi en fonction de sa résistance et de sa bonne rigidité. La lame tranchante (6) y sera incorporée. The case will be made of firm but rigid plastic resistant to the heat of a hot summer sun. The parts will be manufactured by injection of plastic. The plastic used for the cutting block (Fig. 4) will be chosen according to its strength and good rigidity. The sharp blade (6) will be incorporated into it.

La figure 1 représente le dispositif en pièces détachées. Figure 1 shows the device in parts.

La figure 2 représente le dispositif dans son état fini. Figure 2 shows the device in its finished state.

La figure 3 représente le dispositif en coupe transversale. Figure 3 shows the device in cross section.

La figure 4 représente le bloc de coupe vu de profil. Figure 4 shows the cutting block seen in profile.

Le montage du dispositif se fera à partir de la partie inférieure du boitier (2) dans laquelle on placera le bloc de,coupe (Fig. 4) dans l'encoche prévue à cet effet (16). On terminera en encastrant les parties charnières des parties inférieures et supérieures du boitier (10.17).  The mounting of the device will be done from the lower part of the case (2) in which the cutting block (Fig. 4) will be placed in the notch provided for this purpose (16). We will finish by fitting the hinge parts of the lower and upper parts of the housing (10.17).

Le dispositif est destiné à être posé sur toute ceinture de sécurité automobile principalement pour se dégager rapidement et par ses propres moyens d'une ceinture bloquée. Un seul doigt suffit pour actionner le dispositif de coupe.  The device is intended to be placed on any automobile seat belt mainly to quickly disengage and by its own means from a locked belt. A single finger is enough to activate the cutting device.
