Description

La présente invention est relative aux dispositifs destinés à retenir sur son siège un passager d'un véhicule automobile en cas de décélération brusque de celui-ci, par exemple lors d'un freinage d'urgence ou d'une collision.The present invention relates to devices intended to retain a passenger in a motor vehicle in his seat in the event of sudden deceleration thereof, for example during emergency braking or a collision.

Plus particulièrement, l'invention concerne une boucle qui, dans un dispositif du genre indiqué, est destinée à fixer de façon amovible un brin d'une sangle de sécurité à un point fixe de la carrosserie du véhicule, par l'intermédiaire par exemple d'une languette formant pène de verrou.More particularly, the invention relates to a loop which, in a device of the type indicated, is intended to removably fix a strand of a safety strap to a fixed point on the vehicle body, for example by means of '' a tab forming a bolt bolt.

On connaît, dans l'état de la technique, des boucles comportant un boîtier dans lequel est placé un support en forme d'étrier qui est destiné à être fixé à un moyen de retenue fixe par rapport à la carrosserie du véhicule et qui définit entre ses ailes, un couloir de guidage pour le pène débouchant à une extrémité de cet étrier. Ces boucles comportent en outre un organe de verrouillage monté oscillant dans l'étrier autour d'un axe qui est perpendiculaire aux ailes de cet étrier ainsi qu'un organe d'arrêt monté coulissant dans ces ailes et effaçable au moyen d'un bouton de commande, à l'encontre de l'action d'un dispositif élastique de rappel.Known in the prior art, loops comprising a housing in which is placed a bracket in the form of a stirrup which is intended to be fixed to a retaining means fixed relative to the body of the vehicle and which defines between its wings, a guide corridor for the bolt opening at one end of this stirrup. These loops further comprise a locking member mounted oscillating in the stirrup around an axis which is perpendicular to the wings of this stirrup as well as a stop member mounted sliding in these wings and erasable by means of a button. control, against the action of an elastic return device.

Dans ce type de boucles, le pène est retenu dans la boucle par une partie en saillie de l'organe de verrouillage qui vient empêcher le retrait du pène du couloir de verrouillage, par exemple en s'introduisant dans une ouverture ménagée dans le pène. Lors d'une forte traction sur la sangle tendant à retirer le pène de la boucle, cette partie en saillie vient coopérer avec un bord d'arrêt ménagé dans le fond de l'étrier support, éventuellement par déformation élastique de l'axe d'oscillation de l'organe de verrouillage dans l'étrier, ce qui permet d'obtenir une grande efficacité de la boucle et une force de retenue considérable du pène.In this type of loop, the bolt is retained in the loop by a projecting part of the locking member which prevents the withdrawal of the bolt from the locking passage, for example by entering an opening in the bolt. During a strong traction on the strap tending to remove the bolt from the buckle, this projecting part comes to cooperate with a stop edge formed in the bottom of the support stirrup, possibly by elastic deformation of the axis of oscillation of the locking member in the stirrup, which makes it possible to obtain a high efficiency of the buckle and a considerable retaining force of the bolt.

On connaît également d'après le document FR-2.482.430, une boucle pour ceinture de sécurité comprenant un support destiné à être fixé à un moyen de retenue et définissant un passage rectiligne dans lequel le pène peut être introduit et qui définit un point de coulissement pour celui-ci. L'organe de verrouillage du pène est articulé sur le support autour d'un axe qui s'étend parallèlement au plan du passage. Cet organe de verrouillage peut présenter une première surface de butée retenant le pène et s'étendant perpendiculairement au plan du passage, en étant transversal par rapport à celui-ci, en position verrouillée de la boucle tandis que l'organe de verrouillage peut présenter également au moins une seconde surface de butée qui est destinée, dans la position verrouillée de la boucle, à venir en contact avec un organe d'arrêt monté mobile en translation sur le support, dans une direction perpendiculaire à l'axe d'articulation de l'organe de verrouillage. Le déplacement de cet organe d'arrêt libère l'organe de verrouillage et donc le pène lors de l'ouverture de la boucle qui est commandée par un bouton de manoeuvre monté sur le support de manière à pouvoir se déplacer dans la même direction que l'organe d'arrêt.Also known from document FR-2,482,430, a buckle for a seat belt comprising a support intended to be fixed to a retaining means and defining a rectilinear passage into which the bolt can be introduced and which defines a point of sliding for this one. The bolt locking member is articulated on the support around an axis which extends parallel to the plane of the passage. This locking member may have a first abutment surface retaining the bolt and extending perpendicular to the plane of the passage, being transverse with respect thereto, in the locked position of the loop while the locking member may also have at least a second abutment surface which is intended, in the locked position of the loop, to come into contact with a stop member mounted movable in translation on the support, in a direction perpendicular to the axis of articulation of the locking member. The movement of this stop member releases the locking member and therefore the pin when opening the loop which is controlled by an operating button mounted on the support so as to be able to move in the same direction as the stop device.

Des ressorts de rappel sont prévus pour agir sur l'organe de verrouillage, l'organe d'arrêt et le bouton de manoeuvre. L'organe d'arrêt est formé par un corps monobloc présentant des organes de guidage et de maintien des ressorts s'étendant de part et d'autre de ce corps dans des sens opposés perpendiculairement à l'axe d'articulation de l'organe de verrouillage.Return springs are provided to act on the locking member, the stop member and the operating button. The stop member is formed by a one-piece body having means for guiding and holding the springs extending on either side of this body in opposite directions perpendicular to the axis of articulation of the member. lock.

La construction de tels dispositifs présente un certain nombre d'inconvénients notamment au niveau du respect de tolérances assez serrées au cours de -la fabrication, ce qui en augmente les prix de revient.The construction of such devices has a certain number of drawbacks, in particular in terms of respecting fairly tight tolerances during manufacturing, which increases their cost prices.

Par ailleurs, dans la technique automobile moderne, on souhaite réduire autant que possible le poids et l'encombrement des équipements et ce à tous les niveaux et en particulier dans le domaine des équipements de sécurité sans, bien entendu, pour autant sacrifier l'efficacité de ces équipements.Furthermore, in modern automotive technology, it is desired to reduce as much as possible the weight and size of the equipment and this at all levels and in particular in the field of safety equipment without, of course, sacrificing efficiency of this equipment.

Le but de l'invention est donc de fournir une boucle de ceinture de sécurité dont la construction soit simple et le montage aisé, en réduisant le nombre des organes entrant dans la constitution d'une telle boucle.The object of the invention is therefore to provide a seat belt buckle whose construction is simple and easy assembly, by reducing the number of members involved in the constitution of such a buckle.

Un autre but de l'invention est de fournir une boucle de ceinture de sécurité qui soit plus petite et plus légère que les boucles de la technique antérieure et dont la fabrication puisse être entreprise sans le respect de tolérances serrées.Another object of the invention is to provide a seat belt buckle which is smaller and lighter than the buckles of the prior art and the manufacture of which can be undertaken without respecting tight tolerances.

A cet effet, l'invention a pour objet une boucle, notamment de ceinture de sécurité pour véhicule automobile, destinée à fixer de façon amovible un brin de celle-ci à un point fixe de la carrosserie du véhicule, comprenant un ensemble de gâche et un pène solidaire du brin à fixer, l'ensemble de gâche comportant, logés dans un boîtier, un corps destiné à être fixé à un moyen de retenue solidaire du véhicule et qui délimite un passage et un plan de coulissement pour ledit pène, un organe de verrouillage du pène comportant une partie active qui s'engage dans un évidement du pène en position de verrouillage de celui-ci et articulé sur le corps de façon à pouvoir basculer autour d'un axe à peu près parallèle au plan de coulissement et perpendiculaire à la direction de déplacement du pène, entre une position de verrouillage et une position de déverrouillage dudit pène, des moyens sollicitant l'organe de verrouillage vers sa position de verrouillage, des moyens d'éjection du pène, des moyens sollicitant à l'organe de verrouillage vers sa position de déverrouillage et des moyens de commande de déverrouillage dudit organe de verrouillage, caractérisée en ce que lesdits moyens sollicitant l'organe de verrouillage vers sa position de verrouillage et les moyens d'éjection du pène sont constitués par des premiers moyens élastiques dont une extrémité est destinée à coopérer avec le pène lors de son introduction ou de son éjection de la boucle et dont l'autre extrémité est en appui contre une première surface d'appui de l'organe de verrouillage, et en ce que les moyens sollicitant l'organe de verrouillage vers sa position de déverrouillage sont constitués par des seconds moyens élastiques dont une extrémité est en appui contre le corps et dont l'autre extrémité est en appui contre une seconde surface d'appui de l'organe de verrouillage.To this end, the subject of the invention is a buckle, in particular a seat belt for a motor vehicle, intended to removably fix a strand thereof to a fixed point on the vehicle body, comprising a set of keepers and a bolt secured to the strand to be fixed, the strike assembly comprising, housed in a housing, a body intended to be fixed to a retaining means secured to the vehicle and which delimits a passage and a sliding plane for said bolt, a member locking bolt comprising an active part which engages in a recess of the bolt in the locking position of the latter and articulated on the body so as to be able to tilt about an axis approximately parallel to the sliding plane and perpendicular in the direction of movement of the bolt, between a locking position and an unlocking position of said bolt, means urging the locking member towards its locking position, means for ejecting the bolt, means urging the locking member towards its unlocking position and control means for unlocking said locking member, characterized in that said means urging the locking member towards its locking position and the means for ejecting the bolt are constituted by first elastic means, one end of which is intended to cooperate with the bolt during its introduction or its ejection from the loop and the other end of which bears against a first bearing surface of the locking member, and in that the means urging the locking member towards its unlocking position are constituted by second elastic means, one end of which bears against the body and the other end of which bears against a second bearing surface of the locking member.

Cette ouverture 8 est ménagée en regard d'une extrémité du corps 4 et est destinée, par exemple, à permettre le passage d'un moyen de retenue (non représenté) dont une extrémité est fixée sur le véhicule et dont l'autre extrémité est fixée sur le corps 4 par l'intermédiaire, par exemple, d'un évidement 4a ménagé dans celui-ci, de façon à rendre solidaire le corps 4, du véhicule.The housing 1 also includes a second opening 9 formed in the end of the housing, opposite the end in which the opening 8 is made. This opening 8 is formed facing one end of the body 4 and is intended, for example, to allow the passage of a retaining means (not shown), one end of which is fixed to the vehicle and the other end of which is fixed to the body 4 by means, for example, of a recess 4a formed therein, so as to make the body 4 integral with the vehicle.

Selon un autre mode de réalisation de la boucle de ceinture de sécurité selon l'invention, une partie du corps 4 peut faire saillie au-dehors du boîtier 1 à travers l'ouverture 9, de façon à permettre le montage d'une boucle assemblée, sur un véhicule. Cette construction de la boucle permet d'obtenir une plus grande polyvalence de celle-ci.According to another embodiment of the seat belt buckle according to the invention, a part of the body 4 can protrude outside the housing 1 through the opening 9, so as to allow the assembly of an assembled buckle , on a vehicle. This construction of the loop makes it possible to obtain greater versatility thereof.

L'organe de verrouillage 5 présente à l'une de ses extrémités une partie active 10 constituée par exemple par une saillie en double épaisseur du matériau constituant cet organe. A son extrémité opposée à cette partie active, l'organe de verrouillage 5 présente une surface d'actionnement 11 destinée à coopérer avec une surface formant came 12 de l'organe de commande de déverrouillage 6.The locking member 5 has at one of its ends an active part 10 constituted for example by a double thickness projection of the material constituting this member. At its end opposite to this active part, the locking member 5 has an actuating surface 11 intended to cooperate with a cam surface 12 of the unlocking control member 6.

L'organe de verrouillage 5 comporte également une languette 13 s'étendant en direction du corps 4 et présentant une fente 14 dont la fonction sera définie par la suite. Cette languette fait saillie dans une lumière 15 ménagée dans le corps 4 comme cela sera décrit plus en détail par la suite.The locking member 5 also includes a tongue 13 extending towards the body 4 and having a slot 14 whose function will be defined later. This tongue projects into a slot 15 formed in the body 4 as will be described in more detail below.

Cette languette 13 s'étend entre deux spires d'un ressort 16 dont l'une des extrémités est disposée sur un téton de centrage 17 solidaire du corps 4 et dont l'autre extrémité est en appui contre un premier rebord de la lumière 15 en position déverrouillée de la boucle.This tongue 13 extends between two turns of a spring 16, one of the ends of which is disposed on a centering pin 17 secured to the body 4 and the other end of which is in abutment against a first edge of the slot 15 in unlocked position of the buckle.

La fente 14 de la languette 13 de l'organe de verrouillage permet le passage du fil constituant le ressort 16 de sorte que la languette présente une première et une seconde surfaces d'appui coopérant avec les parties respectives de ressort disposées de part et d'autre de cette languette.The slot 14 of the tongue 13 of the locking member allows the passage of the wire constituting the spring 16 so that the tongue has first and second support surfaces cooperating with the respective parts of the spring arranged on either side. another of this tab.

Comme on le verra par la suite, le guidage de l'une des parties de ressort est assuré par la lumière 15 et au moins une patte de guidage 18 s'étendant au-dessus de celle-ci.As will be seen later, the guiding of one of the spring parts is ensured by the lumen 15 and at least one guide tab 18 extending above the latter.

Il est également à noter que la languette 13 de l'organe de verrouillage 5 comporte des parties en saillie, qui seront décrites plus en détail par la suite, s'étendant de part et d'autre de cette languette et définissant un axe d'articulation 19 de cet organe de verrouillage sur le corps, cet axe d'articulation étant à peu près parallèle au plan de coulissement et perpendiculaire à la direction de déplacement du pène dans le corps. Cette articulation permet à l'organe de verrouillage de basculer entre une position de verrouillage et une position de déverrouillage.It should also be noted that the tongue 13 of the locking member 5 has protruding parts, which will be described in more detail below, extending on either side of this tongue and defining an axis of articulation 19 of this locking member on the body, this axis of articulation being approximately parallel to the sliding plane and perpendicular to the direction of movement of the bolt in the body. This articulation allows the locking member to switch between a locking position and an unlocking position.

Dans la position de déverrouillage de la boucle, représentée sur cette Fig. 1, les parties du ressort 16 s'étendant de part et d'autre de la languette 13, c'est-à-dire une première partie 20 dont l'une des extrémités prend appui sur le premier rebord de la lumière 15 et dont l'autre extrémité prend appui sur la première surface d'appui de la languette 13 et une seconde partie 21 dont l'une des extrémités est disposée sur le téton de centrage 17 et dont l'autre extrémité est en appui contre la seconde surface d'appui de la languette, exercent une force égale sur cette languette de manière à définir la position de déverrouillage de l'organe de verrouillage 5.In the unlocking position of the buckle, shown in this fig. 1, the parts of the spring 16 extending on either side of the tongue 13, that is to say a first part 20, one of the ends of which bears on the first edge of the slot 15 and of which the other end bears on the first bearing surface of the tongue 13 and a second part 21, one of the ends of which is disposed on the centering pin 17 and the other end of which bears against the second surface d support of the tongue, exert an equal force on this tongue so as to define the unlocking position of the member lock 5.

Dans ce mode de réalisation, les première et seconde parties du ressort agissent dans une direction à peu près parallèle au plan de coulissement du pène.In this embodiment, the first and second parts of the spring act in a direction approximately parallel to the sliding plane of the bolt.

Il est à noter que la languette 13 n'est pas disposée au milieu du ressort 16, de sorte que le nombre de spires de la première partie de celui-ci est supérieur à celui de la seconde. Ainsi, la force de la première partie est supérieure à celle de la seconde et la position d'équilibre, représentée sur cette Fig. 1, est obtenue par le fait que la distance séparant la languette 13 du premier rebord de la lumière 15 est supérieure à celle séparant cette même languette 13 du téton de centrage 17.It should be noted that the tongue 13 is not disposed in the middle of the spring 16, so that the number of turns of the first part of it is greater than that of the second. Thus, the force of the first part is greater than that of the second and the equilibrium position, shown in this FIG. 1, is obtained by the fact that the distance separating the tongue 13 from the first edge of the slot 15 is greater than that separating this same tongue 13 from the centering pin 17.

Comme on peut le voir sur la Fig. 2, qui représente une boucle de ceinture de sécurité selon l'invention, en position verrouillée, lorsque l'on introduit un pène 22 comportant un évidement 23 dans la boucle, la face frontale 24 de celui-ci vient en appui contre l'extrémité de la première partie 20 du ressort 16 qui était en appui contre le premier rebord de la lumière 15. Ceci a pour effet de rompre l'équilibre des forces qui s'exerçaient sur la languette 13 de l'organe de verrouillage 5. En effet, la force exercée par la partie 20 du ressort devient supérieure à celle exercée par la partie 21, de sorte que l'organe de verrouillage bascule autour de son axe d'articulation jusqu'à ce que la partie active 10 vienne en appui sur la surface supérieure du pène 22. L'engagement du pène 22 se poursuivant, la partie 20 de ressort se comprime de plus en plus, de sorte que lorsque l'évidement 23 du pène arrive en regard de la partie active 10 de l'organe de verrouillage 5, celui-ci bascule vers la position de verrouillage représentée sur cette figure, dans laquelle la partie active 10 coopère avec le rebord de la lumière 15 qui constitue donc un rebord d'arrêt, et avec un rebord de l'évidement 23 du pène 22 pour retenir celui-ci dans la boucle. Dans cette position, la force exercée par la partie 20 du ressort 16 est supérieure à celle exercée par la partie 21 de sorte que l'organe de verrouillage est maintenu en position de verrouillage.As can be seen in Fig. 2, which represents a seat belt buckle according to the invention, in the locked position, when a bolt 22 is inserted having a recess 23 in the buckle, the front face 24 of the latter comes to bear against the end of the first part 20 of the spring 16 which was in abutment against the first edge of the slot 15. This has the effect of upsetting the balance of forces which were exerted on the tongue 13 of the locking member 5. Indeed , the force exerted by the part 20 of the spring becomes greater than that exerted by the part 21, so that the locking member rocks around its axis of articulation until the active part 10 comes to bear on the upper surface of the bolt 22. The engagement of the bolt 22 continues, the part 20 of spring compresses more and more, so that when the recess 23 of the bolt comes opposite the active part 10 of the member locking 5, this switches to the locking position shown Entered in this figure, in which the active part 10 cooperates with the edge of the light 15 which therefore constitutes a stop edge, and with a edge of the recess 23 of the bolt 22 to retain the latter in the loop. In this position, the force exerted by the part 20 of the spring 16 is greater than that exerted by the part 21 so that the locking member is kept in the locking position.

Lorsqu'un effort F (Fig. 3) est exercé sur l'organe de commande de déverrouillage 6, la surface formant came 12 de celui-ci vient en appui contre la surface d'actionnement 11 de l'organe de verrouillage 5. Ceci a pour effet de faire basculer l'organe de verrouillage 5 à l'encontre de l'action exercée par la partie 20 du ressort. Si l'on poursuit l'action jusqu'à ce que la partie active 10 de l'organe de verrouillage 5 se dégage de la lumière 15 du corps 4 et de l'évidement 23 du pène 22, celui-ci n'est alors plus retenu dans la boucle et la partie 20 du ressort se détend pour éjecter le pène 22 de la boucle.When a force F (Fig. 3) is exerted on the unlocking control member 6, the cam surface 12 of the latter comes to bear against the actuating surface 11 of the locking member 5. This has the effect of tilting the locking member 5 against the action exerted by the part 20 of the spring. If the action is continued until the active part 10 of the locking member 5 emerges from the lumen 15 of the body 4 and of the recess 23 of the bolt 22, the latter is then more retained in the loop and the part 20 of the spring relaxes to eject the bolt 22 from the loop.

Comme on peut le voir sur la Fig. 4, cette détente de la partie 20 du ressort se poursuit tant que l'extrémité de celui-ci n'est pas en appui contre le premier rebord de la lumière 15, de manière que les forces exercées par cette première partie du ressort et par la deuxième partie de celui-ci, soient égales et, ainsi, définissent la position de déverrouillage telle que décrite en regard de la Fig. 1.As can be seen in Fig. 4, this relaxation of the part 20 of the spring continues as long as the end of the latter is not in abutment against the first edge of the slot 15, so that the forces exerted by this first part of the spring and by the second part of it, are equal and, thus, define the unlocking position as described with reference to FIG. 1.

On voit donc que la première partie 20 du ressort 16 dont l'une des extrémités est destinée à coopérer avec le pène lors de son introduction ou de son éjection de la boucle et dont l'autre extrémité est en appui contre une première surface d'appui de l'organe de verrouillage, constitue des premiers moyens élastiques qui sollicitent l'organe de verrouillage vers sa position de verrouillage lors de l'introduction du pène dans la boucle et qui éjectent celui-ci de la boucle lorsqu'une action est exercée sur l'organe de commande de déverrouillage. La seconde partie 21 du ressort, dont l'une des extrémités est en appui contre le corps 4 et dont l'autre extrémité est en appui contre une seconde surface d'appui de l'organe de verrouillage, constitue, quant à elle, des seconds moyens élastiques sollicitant l'organe de verrouillage 5 vers sa position de déverrouillage, à la suite de l'actionnement de l'organe de commande de déverrouillage.It can therefore be seen that the first part 20 of the spring 16, one of the ends of which is intended to cooperate with the bolt during its introduction or of its ejection from the loop and the other end of which bears against a first surface of support of the locking member, constitutes first elastic means which urge the locking member towards its locking position during the introduction of the bolt into the loop and which eject it from the loop when an action is exerted on the unlocking control member. The second part 21 of the spring, one end of which bears against the body 4 and the other end of which bears against a second bearing surface of the locking member, constitutes, for its part, second elastic means urging the locking member 5 towards its unlocking position, following actuation of the unlocking control member.

Les première et seconde surfaces d'appui de l'organe de verrouillage sont ménagées l'une en regard de l'autre de part et d'autre de la languette 13 de celui-ci.The first and second bearing surfaces of the locking member are arranged one opposite the other on either side of the tongue 13 thereof.

Sur la Fig. 5, on a représenté un mode de réalisation d'un corps 4 entrant dans la constitution d'une boucle de ceinture de sécurité selon l'invention.In Fig. 5, there is shown an embodiment of a body 4 forming part of a seat belt buckle according to the invention.

Ainsi qu'on l'a déjà vu, ce corps 4 comporte un passage pour l'extrémité du pène, ce passage étant délimité par deux rebords, dont un seul, 25, est représenté, formés dans les deux branches du U constituant ledit corps. Ce corps 4 comporte dans sa partie centrale, la lumière 15 présentant deux rebords, 26 et 27, de guidage du ressort 16, et plus particulièrement de la première partie 20 de celui-ci. Le corps 4 présente également au moins une patte de guidage 18 avantageusement venue de matière avec l'une de ses ailes, et s'étendant au moins en partie au-dessus de cette partie 20 du ressort 16 pour assurer son guidage, la première partie 20 du ressort étant disposée entre les rebords 26 et 27 de la lumière 15 et ladite au moins une patte de guidage.As we have already seen, this body 4 has a passage for the end of the bolt, this passage being delimited by two flanges, only one of which, 25, is shown, formed in the two branches of the U constituting said body . This body 4 comprises in its central part, the lumen 15 having two flanges, 26 and 27, for guiding the spring 16, and more particularly of the first part 20 thereof. The body 4 also has at least one guide tab 18 advantageously made integrally with one of its wings, and extending at least partly above this part 20 of the spring 16 to guide it, the first part 20 of the spring being disposed between the flanges 26 and 27 of the slot 15 and said at least one guide tab.

Les ailes du corps 4 comportent également des logements dont un seul, 29, est représenté, ces logements étant ouverts dans leur partie supérieure pour permettre le montage de l'organe de verrouillage et comportant des ailettes 30 pouvant être rabattues après montage de cet organe de verrouillage, pour retenir les parties en saillie de celui-ci, dans ces logements.The wings of the body 4 also include housings of which only one, 29, is shown, these housings being open in their upper part to allow the mounting of the locking member and comprising fins 30 which can be folded down after mounting of this member. locking, to retain the projecting parts thereof, in these housings.

L'une des extrémités du ressort 16 est disposée comme on l'a vu sur le téton de centrage 17 tandis que son autre extrémité vient en appui contre un premier rebord 31 de la lumière 15.One of the ends of the spring 16 is arranged as seen on the centering pin 17 while its other end bears against a first flange 31 of the slot 15.

L'organe de verrouillage 5, représenté sur la Fig. 6, comporte à l'une de ses extrémités la partie active 10 constituée par exemple par une saillie en double épaisseur du matériau constituant cet organe de verrouillage. A son autre extrémité l'organe de verrouillage comporte la surface d'actionnement 11 qui peut être avantageusement constituée par une partie découpée de la languette 13. De part et d'autre de cette languette 13, s'étendent deux parties en saillie 32 et 33 définissant l'axe d'articulation 19 de l'organe de verrouillage sur le corps et s'engageant dans les logements, 29, de celui-ci de façon à permettre le basculement de l'organe de verrouillage par rapport audit corps. La languette 13 comporte également la fente 14 à travers laquelle passe le fil constituant le ressort 16.The locking member 5, shown in FIG. 6, comprises at one of its ends the active part 10 constituted for example by a double thickness projection of the material constituting this locking member. At its other end, the locking member comprises the actuating surface 11 which may advantageously consist of a cut-out part of the tongue 13. On either side of this tongue 13, extend two protruding parts 32 and 33 defining the axis of articulation 19 of the 'locking member on the body and engaging in the housings, 29, thereof so as to allow the tilting of the locking member relative to said body. The tongue 13 also has the slot 14 through which the wire constituting the spring 16 passes.

Ainsi qu'on peut le voir sur la Fig. 7, les parties en saillie 32 et 33 de l'organe de verrouillage 5 sont disposées dans les logements correspondants des ailes du corps 4. La partie 20 du ressort est disposée entre les rebords 26 et 27 de la lumière 15 du corps 4 et par exemple deux pattes de guidage 18 et 35 venues de matière avec ce corps 4. Le ressort 16 est ainsi retenu en quatre points.As can be seen in FIG. 7, the projecting parts 32 and 33 of the locking member 5 are disposed in the corresponding housings of the wings of the body 4. The part 20 of the spring is disposed between the flanges 26 and 27 of the slot 15 of the body 4 and by example two guide tabs 18 and 35 integrally formed with this body 4. The spring 16 is thus retained at four points.
