Description

I La présente invention concerne les sacs de sécurité gonflables et, plusI The present invention relates to airbags and, more

particulièrement, la réalisation de tels  particularly, the realization of such

sacs destinés à équiper les véhicules automobiles.  bags for use in motor vehicles.

Les sacs de sécurité gonflables conventionnels sont obtenus en cousant le tissu constitutif du sac à la forme que l'on désire obtenir. Ces sacs de sécurité gonflables conventionnels présentent alors l'inconvénient qu'ils sont parfois d'une étanchéité imparfaite en raison, lors du gonflage, de fuites de gaz occasionnées par les trous de  Conventional air bags are obtained by sewing the fabric of the bag to the shape that one wishes to obtain. These conventional inflatable safety bags then have the disadvantage that they are sometimes of an imperfect seal due to, during inflation, gas leaks caused by the holes of

La présente invention a pour objet de remédier à cet inconvénient présenté par les sacs de sécurité gonflable conventionnels, et elle propose à cet effet un procédé de réalisation d'un sac de sécurité gonflable qui, tout en étant d'une grande simplicité et d'une grande fiabilité,  The object of the present invention is to remedy this drawback presented by conventional inflatable safety bags, and to this end it proposes a method for producing an inflatable safety bag which, while being very simple and high reliability,

assure une totale étanchéité au gaz lors du gonflage du sac.  ensures complete gas tightness when the bag is inflated.

A cet effet le procédé de réalisation d'un sac de sécurité gonflable, selon lequel on assemble le long de leur périphérie les deux faces de l'élément gonflable du sac, se caractérise par le fait que cet assemblage est réalisé par soudage. Ce soudage peut être réalisé thermiquement, par  To this end, the process for producing an inflatable safety bag, according to which the two faces of the inflatable element of the bag are assembled along their periphery, is characterized by the fact that this assembly is carried out by welding. This welding can be done thermally, by

haute fréquence ou par ultrasons.high frequency or ultrasonic.

Selon l'invention, l'élément gonflable du sac de sécurité peut être réalisé à partir des faces en tissu du sac qui sont soudées ensemble. En variante, une couture peut être réalisée dans la soudure, notamment au milieu de la soudure, en servant de moyen d'assemblage de sécurité en cas  According to the invention, the inflatable element of the safety bag can be produced from the fabric faces of the bag which are welded together. Alternatively, a seam can be made in the weld, in particular in the middle of the weld, serving as a safety assembly means in the event of

de rupture de la soudure.weld failure.

L'élément gonflable du sac de sécurité peut aussi être constitué par une vessie (en film polyéthylène, en polyuréthanne, en copolyamide, en copolyester ou en chlorure de polyvinyle) qui est soudée à la forme du sac, et qui est intégrée dans un sac cousu. Cette réalisation permet d'avoir une excellente étanchéité grâce à la vessie soudée, tout en bénéficiant de la tenue mécanique donnée par le tissu du sac  The inflatable element of the safety bag can also be constituted by a bladder (made of polyethylene film, polyurethane, copolyamide, copolyester or polyvinyl chloride) which is welded to the shape of the bag, and which is integrated into a bag. sewn. This embodiment provides excellent sealing thanks to the welded bladder, while benefiting from the mechanical strength given by the fabric of the bag.

et par les coutures.and by the seams.

Pour bien faire comprendre l'invention on en décrira ci-après, à titre d'exemples sans caractère limitatif, des formes d'exécution préférées en référence au dessin schématique annexé dans lequel: la figure 1 est une vue schématique en coupe montrant la réalisation d'un sac de sécurité gonflable par soudage en périphérie des faces du sac, ce dernier étant disposé à plat; la figure 2 est une vue analogue à la figure 1, le sac étant retourné pour l'opération de soudage; la figure 3 est une vue schématique en coupe verticale montrant la réalisation d'un sac de sécurité gonflable par soudage d'une vessie en film polyéthylène et intégration de celle-ci dans un sac cousu; et la figure 4 est une vue analogue à la figure 1,  To make the invention better understood, there will be described below, by way of examples without limitation, preferred embodiments with reference to the appended schematic drawing in which: FIG. 1 is a schematic sectional view showing the embodiment an inflatable safety bag by welding on the periphery of the faces of the bag, the latter being disposed flat; Figure 2 is a view similar to Figure 1, the bag being turned over for the welding operation; Figure 3 is a schematic view in vertical section showing the production of an inflatable safety bag by welding a bladder in polyethylene film and integration thereof into a sewn bag; and FIG. 4 is a view similar to FIG. 1,

montrant la réalisation d'une couture dans la soudure.  showing the realization of a seam in the weld.

En référence à la figure 1, on réalise un sac de sécurité gonflable 1 en disposant à plat, en regard, les deux faces de tissu enduit 2, 3 du sac, et en soudant ensemble thermiquement, en 4, 5, la périphérie des faces 2 et 3. On obtient ainsi un sac dont l'assemblage par soudage  With reference to FIG. 1, an inflatable safety bag 1 is produced by placing the two faces of coated fabric 2, 3 of the bag flat, facing each other, and by thermally welding together, at 4, 5, the periphery of the faces. 2 and 3. A bag is thus obtained whose assembly by welding

permet une excellente étanchéité aux gaz de gonflage.  provides excellent sealing against inflation gases.

Dans la variante représentée à la figure 2, les deux faces de tissu enduit 6, 7 du sac de sécurité gonflable 8 sont placées en regard l'une de l'autre, avec leurs bords périphériques retournés vers l'intérieur et soudés  In the variant shown in FIG. 2, the two faces of coated fabric 6, 7 of the inflatable safety bag 8 are placed facing one another, with their peripheral edges turned inward and welded

thermiquement ensemble en 9, 10.thermally together in 9, 10.

Selon la forme d'exécution de la figure 3, on soude en 11, 12, à la forme du sac, une vessie 13 en film polyéthylène, et la vessie 13 est intégrée dans un sac 14 dont les faces 15, 16 en tissu enduit sont assemblées par des coutures 17. Avec cette réalisation, on obtient une totale étanchéité par utilisation de la vessie 13, tout en ayant une excellente tenue mécanique par le tissu du sac 14  According to the embodiment of Figure 3, is welded in 11, 12, to the shape of the bag, a bladder 13 in polyethylene film, and the bladder 13 is integrated in a bag 14 whose faces 15, 16 in coated fabric are joined by seams 17. With this embodiment, a total seal is obtained by using the bladder 13, while having excellent mechanical strength by the fabric of the bag 14

et les coutures 17.and the seams 17.

Enfin, dans la variante de réalisation de la figure 4, le sac 1' est obtenu comme sur la figure 1 (par soudage 4', 5' des bords périphériques des faces de tissu 2', 3' du sac), puis on effectue une couture 18, 19 au milieu de chaque soudure, 4', 5'. Cette réalisation permet, dans l'éventualité o une soudure 4', 5' casserait, de disposer alors d'un second mode d'assemblage maintenant l'intégrité  Finally, in the alternative embodiment of Figure 4, the bag 1 'is obtained as in Figure 1 (by welding 4', 5 'of the peripheral edges of the fabric faces 2', 3 'of the bag), then we carry out a seam 18, 19 in the middle of each weld, 4 ', 5'. This embodiment allows, in the event that a 4 ′, 5 ′ weld breaks, to then have a second method of assembly maintaining integrity

du sac.from the bag.

On comprendra que la description ci-dessus a été  It will be understood that the above description has been

donnée à simple titre d'exemple, sans caractère limitatif, et que des adjonctions ou des modifications constructives pourraient y être apportées sans sortir du cadre de la présente invention. Ainsi, le sac selon l'invention pourrait être obtenu à partir d'un tissu non enduit (au lieu d'un tissu enduit) et le soudage, au lieu d'être réalisé thermiquement, pourrait être un soudage par haute fréquence  given by way of example, without limitation, and that additions or constructive modifications could be made without departing from the scope of the present invention. Thus, the bag according to the invention could be obtained from an uncoated fabric (instead of a coated fabric) and the welding, instead of being performed thermally, could be a high frequency welding

ou par ultrasons.or by ultrasound.

De même, dans la forme d'exécution de la figure 3, on a décrit la vessie 13 comme constituée par un film de polyéthylène, mais on comprendra que cette vessie pourrait tout aussi bien être en polyuréthanne, en copolyamide, en  Likewise, in the embodiment of FIG. 3, the bladder 13 has been described as consisting of a polyethylene film, but it will be understood that this bladder could just as easily be made of polyurethane, of copolyamide,

copolyester ou en chlorure de polyvinyle.  copolyester or polyvinyl chloride.
