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 verrouil­ lage 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 lock member lage in the stirrup, which allows to obtain a high efficiency of the loop and a considerable holding 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.

On connait également d'après le document US-A 3 399 431, 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 destinée à être fixé à un moyen de retenue solidaire du véhicule, qui délimite un passage et un plan de coulissement pour ledit pène, des moyens de verrouil­lage du pène dans la boucle, constitués par une partie en saillie du corps s'étendant dans ledit passage, et destinée à s'engager dans un évidement du pène, en position de verrouillage de celui-ci, des moyens de commande de déverrouillage du pène, des moyens d'éjec­tion de celui-ci et des moyens de maintien du pène en position de verrouillage sur ladite partie en saillie du corps, constitués par un coulisseau monté déplaça­ble par ledit pène lors de son introduction, dans le corps dans la direction générale de déplacement du pène.Also known from document US-A 3 399 431 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 strike assembly 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 integral with the vehicle, which delimits a passage and a sliding plane for said bolt , means for locking the bolt in the loop, constituted by a projecting part of the body extending in said passage, and intended to engage in a recess in the bolt, in the locking position of the latter, means for control for unlocking the bolt, means for ejecting it and means for holding the bolt in the locked position on said protruding part of the body, constituted by a slide mounted movable by said bolt during its introduction, into thebody in the general direction of movement of the bolt.

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 manufacture, 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 a 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 vénicule 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 destinée à être fixé à un moyen de retenue solidaire du véhicule, qui délimite un passage et un plan de coulissement pour ledit pène, des moyens de verrouil­lage du pène dans la boucle, constitués par une partie en saillie du corps s'étendant dans ledit passage, et destinée à s'engager dans un évidement du pène, en position de verouillage de celui-ci, des moyens de commande de déverrouillage du pène, des moyens d'éjec­tion de celui-ci et des moyens de maintien du pène en position de verrouillage sur ladite partie en saillie du corps, constitués par un coulisseau monté déplaça­ble par ledit pène lors de son introduction, dans le corps dans la direction générale de déplacement du pène, ledit coulisseau étant solicité par un organe élastique de rappel et coopérant en position de ver­rouillage de pène, avec le corps et une surface cor­respondante du pène pour maintenir celui-ci en posi­tion, sous l'action dudit organe élastique, ledit coulisseau étant monté déplaçable dans ledit corps sous l'action des moyens de commande de déverrouillage entre la position de maintien et une position de libération du pène, dans laquelle il coopère avec lesdits moyens d'éjection pour éjecter le pène de la boucle, lesdits moyens d'éjection étant constitués par ledit organe élastique de rappel dont l'une des extré­mités est en appui contre le coulisseau et l'autre, contre un organe de déverrouillage du pène, articulé dans le corps pour déverrouiller le pène en dégageant l'évidement de celui-ci de la partie en saillie du corps à la suite d'une action exercée sur le coulis­seau par les moyens de commande de déverrouillage du pène, caractérisée en ce que l'organe de déverrouilla­ge est constitué par une pièce de manoeuvre présentant deux branches s'étendant à peu près à 90° l'une par rapport à l'autre, dont l'une coopère avec l'organe élastique, et l'autre avec une surface correspondante du pène, pour déverrouiller celui-ci, et une surface d'articulation coopérant avec le corps.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 striker assembly 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, which delimits a passage and a sliding plane for said bolt, locking means of the bolt in the loop, constituted by a projecting part of the body extending in said passage, and intended to engage in a recess of the bolt, in the locked position thereof, of the bolt unlocking control means , means for ejecting it and means for holding the bolt in the locked position on said projecting part of the body, constituted by a slide mounted movable by said bolt in its introduction, in the body in the direction general movement of the bolt, said slider being solicited by an elastic return member and cooperating in the bolt locking position, with the body and a corresponding surface of the bolt to maintain the latter in position, under the action of said elastic member, said slide being mounted movable in said body under the action of the unlocking control means between the holding position and a position release of the bolt, in which it cooperates with said ejection means to eject the bolt from the loop, said ejection means being constituted by said elastic return member one of the ends of which bears against the slide and the other, against a bolt unlocking member, articulated in the body to unlock the bolt by releasing the recess of the latter from the projecting part of the body following an action exerted on the slide by the control means for unlocking the bolt, characterized in that the unlocking member is constituted by an operating part having two branches extending approximately 90 ° relative to one another, one of which cooperates with the 'elastic member, and the other with a corresponding surface of the bolt, to unlock the latter, and a hinge surface cooperating with the body.

A l'intérieur de ce boîtier 1 est disposé un ensemble de gâche comportant un corps 4 destiné à être fixé à un moyen de retenue (non repré­senté) solidaire du véhicule.As shown in FIG. 1, a seat belt buckle according to the invention comprises a housing 1 constituted for example, in a manner known per se, of an upper element 2 and of a lower element 3. Inside this box 1 is disposed a striker assembly comprising a body 4 intended to be fixed to a retaining means (not shown) secured to the vehicle.

Le boîtier 1 comporte également une première ouverture 5 dont les parois sont inclinées, débouchant dans le corps 4, qui définit un passage et un plan de coulissement pour, par exemple, une languette formant pène de verrou, solidaire d'un brin à fixer de la ceinture de sécurité.The housing 1 also includes a first opening 5 whose walls are inclined, opening into the body 4, which defines a passage and a sliding plane for, for example, a tongue forming a bolt bolt, secured to a strand to be fixed seat belt.

Le boîtier 1 comporte également une seconde ouverture 6 ménagée dans l'extrémité du boîtier oppo­sée à l'extrémité dans laquelle est pratiquée l'ouver­ture 5. Cette ouverture 6 est ménagée en regard d'une extrémité du corps 4 est 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 6 formed in the end of the housing opposite the end in which the opening 5 is made. This opening 6 is formed opposite one end of the body 4 and is intended for example to allow the passage of a retaining means (not shown) whose one end is fixed on the vehicle and the other end is fixed to the body 4 by means for example of a recess 4 has provided 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 boi­tier 1 à travers l'ouverture 6, de façon à permettre le montage d'une boucle assemblée sur un véhicule.According to another embodiment of the seat belt buckle according to the invention, a part of the body 4 can protrude outside the case 1 through the opening 6, so as to allow the assembly of an assembled buckle on a vehicle.

Cette construction de la boucle permet d'ob­tenir une plus grande polyvalence de celle-ci.This construction of the loop makes it possible to obtain greater versatility thereof.

La boucle de ceinture de sécurité selon l'invention comporte également un coulisseau 7 monté déplaçable à coulissement dans ledit corps entre une position avant et une position arrière comme on le verra par la suite, suivant la direction générale de déplacement du pène dans le corps. Ce coulisseau 7 comporte un bossage de guidage 7a disposé dans une première lumière 8 d'une première partie 9 du corps 4 pour assurer son guidage lors de son déplacement.The seat belt buckle according to the invention also comprises a slider 7 mounted so that it can slide in said body between a front position and a rear position as will be seen later, in the general direction of movement of the bolt in the body. This slider 7 includes a guide boss 7 is disposed in a first lumen 8 of a first part 9 of the body 4 to ensure its guiding during its movement.

Le coulisseau comporte également un téton de centrage 10 destiné à recevoir une extrémité d'un res­sort 11 dont la fonction sera définie par la suite et dont l'autre extrémité est centrée sur un téton 12 d'un organe de déverrouillage 13 du pène, articulé sur le corps 4.The slide also comprises a centering pin 10 intended to receive one end of a spring 11 whose function will be defined below and whose other end is centered on a pin 12 of an unlocking member 13 of the bolt, articulated on the body 4.

Cet organe de déverrouillage 13 est consti­tué par une pièce de manoeuvre présentant deux bran­ches 13a, 13b s'étendant à peu près à 90° l'une par rapport à l'autre, et dont l'une coopère avec le ressort 11 et l'autre avec une surface correspondante du pène pour déverrouiller celui-ci comme cela sera décrit plus en détail par la suite.This unlocking member 13 is constituted by an operating part having two branches 13a, 13b extending approximately 90 ° relative to each other, and one of which cooperates with the spring 11 and the another with a corresponding surface of the bolt to unlock the bolt as will be described in more detail below.

Cet organe de déverrouillage comporte égale­ment une surface d'articulation 14 coopoérant avec le corps et plu particulièrement avec un bord d'arrêt de celui-ci pour permettre son basculement par rapport à celui-ci.This unlocking member also includes an articulation surface 14 cooperating with the body and more particularly with a stop edge of the latter to allow it to tilt relative to the latter.

Il est à noter que la branche 13a de cet or­gane de déverrouillage s'étend en direction d'une seconde lumière 15 d'une seconde partie 16 du corps 4 s'étendant à peu près parallèlement et à une certaine distance de la première partie de celui-ci, définissant ainsi le passage et le plan de coulissement pour le pène. Cette seconde partie 16 du corps 4 comporte également une partie en saillie 17, par exemple embou­tie, à proximité de la lumière 15, et s'étendant dans le passage défini par le corps, cette partie en sail­lie présentant un bord d'arrêt 17a destiné comme on le verra par la suite à coopérer avec un rebord d'un évi­dement du péne pour verrouiller celui-ci à l'intérieur de la boucle.It should be noted that the branch 13a of this unlocking member extends in the direction of a second lumen 15 of a second part 16 of the body 4 extending approximately parallel and at a certain distance from the first part of this, thus defining the passage and the sliding plane for the bolt. This second part 16 of the body 4 also includes a projecting part 17, for example stamped, near the lumen 15, and extending in the passage defined by the body, this projecting part having a stop edge 17a intended as will be seen subsequently to cooperate with a rim of a recess of the bolt to lock the latter inside the loop.

Il est également à noter que la surface du coulisseau destinée à coopérer avec la face frontale du pène lors de son introduction dans la boucle, pré­sente au moins une rampe 18 dont la fonction sera dé­finie par la suite.It should also be noted that the surface of the slider intended to cooperate with the front face of the bolt during its introduction into the loop, has at least one ramp 18 whose function will be defined later.

Dans la position déverrouillée de la boucle représentée sur cette Fig.1, le coulisseau est en ap­pui contre une surface de butée de la première partie 9 du corps. Lorsqu'un utilisateur introduit un pène 19 comportant un évidement 20, entre les deux parties du corps 4, la face frontale de celui-ci vient en appui contre le coulisseau 7 et plus particulièrement contre ladite au moins une rampe 18 de celui-ci. Si l'intro­duction du pène se poursuit (Fig.2), le coulisseau se déplace à mesure que le pène pénètre dans la boucle, en comprimant le ressort 11. Cette compression du ressort 11 a pour effet de faire basculer l'organe de déverrouillage 13 autour de sa surface d'articulation jusqu'à ce que la branche 13b de celui-ci soit en ap­pui contre la première partie 9 du corps 4. Durant ce déplacement, la face frontale du pène étant en appui contre la rampe du coulisseau, ce dernier exerce une action sur le pène qui tend à le faire remonter vers la seconde partie 16 du corps 4. Cependant, cette remontée est arrêtée par la venue en contact des parties pleines du pène contre la partie en saillie 17 du corps 4. Lorsque l'évidement 20 du pène arrive en regard de cette partie en saillie 17, le pène peut alors remonter dans le corps 4 sous l'action de la rampe du coulisseau et de la force exercée sur celui-­ci par le ressort 11.In the unlocked position of the loop shown in this Fig.1, the slider bears against an abutment surface of the first part 9 of the body. When a user introduces a bolt 19 comprising a recess 20, between the two parts of the body 4, the front face of the latter comes to bear against the slide 7 and more particularly against said at least one ramp 18 thereof. If the introduction of the bolt continues (Fig. 2), the slide moves as the bolt enters the loop, compressing the spring 11. This compression of the spring 11 has the effect of tilting the unlocking member 13 around its articulation surface until the branch 13 b thereof is in abutment against the first part 9 of the body 4. During this movement, the front face of the bolt being in abutment against the ramp of the slide , the latter exerts an action on the bolt which tends to make it go up towards the second part 16 of the body 4. However, this ascent is stopped by the coming into contact of the solid parts of the bolt against the projecting part 17 of the body 4. When the recess 20 of the bolt comes opposite this projecting part 17, the bolt can then go back into the body 4 under the action of the slide ramp and the force exerted on it by the spring 11.

Ainsi, et comme il est représenté sur la Fig.3, lorsque l'évidement 20 du pène 19 est totale­ment engagé sur la partie en saillie 17 du corps 4, le coulisseau 7 peut se déplacer vers l'avant sous l'ac­tion du ressort 11 afin de venir coopérer avec la première partie du corps 4 et une surface correspon­dante du pène 19 pour maintenir l'évidement du pene en position de verrouillage autour de la partie en sail­ lie. Lorsqu'une traction est exercée sur le pène tendant à le faire sortir de la boucle,la partie en saillie 17 du corps 4 et plus particulièrement le bord d'arrêt 17a de celle-ci et le rebord correspondant de l'évidement 20 du pène coopérent ensemble pour retenir le pène dans la boucle. D'autre part,le coulisseau 7 empêche tout déplacement du pêne tendant à le dégager de la partie en saillie du corps.Thus, and as shown in FIG. 3, when the recess 20 of the bolt 19 is fully engaged on the projecting part 17 of the body 4, the slide 7 can move forward under the action of the spring 11 in order to come to cooperate with the first part of the body 4 and a corresponding surface of the bolt 19 to maintain the recess of the bolt in the locking position around the part in sail lie. When traction is exerted on the bolt tending to make it come out of the loop, the projecting part 17 of the body 4 and more particularly the stop edge 17 a thereof and the corresponding rim of the recess 20 of the bolts work together to hold the bolt in the loop. On the other hand, the slide 7 prevents any movement of the bolt tending to disengage it from the projecting part of the body.

Lorsque l'utilisateur désire déverrouiller la boucle selon l'invention, il agit sur les moyens de commande de déverrouillage (non représentés) qui coo­pèrent avec par exemple des parties en saillie du cou­lisseau 7 pour déplacer celui-ci vers une position arrière de libération du pène 19. Ce déplacement a également pour effet de comprimer le ressort 11 et de faire basculer l'organe de déverrouillage 13 autour de sa surface d'articulation de sorte que la branche 13a de celui-ci vient en appui contre une surface corres­pondante du pène et amène celui-ci, et plus particu­lièrement l'évidement 20, à se dégager de la partie en saillie 17 du corps 4.When the user wishes to unlock the loop according to the invention, he acts on the unlocking control means (not shown) which cooperate with, for example, protruding parts of the slide 7 to move the latter towards a rear position for releasing the bolt 19. This displacement also has the effect of compressing the spring 11 and of tilting the unlocking member 13 around its articulation surface so that the branch 13a thereof comes to bear against a corresponding surface of the bolt and causes the latter, and more particularly the recess 20, to disengage from the projecting part 17 of the body 4.

L'utilisateur relâchant son action sur les moyens de commande de déverrouillage, le ressort exer­ce une action sur le coulisseau 7 pour le ramener vers sa position avant et coopérer ainsi avec la face fron­tale du pène pour l'éjecter hors du corps 4.The user releasing his action on the unlocking control means, the spring acts on the slide 7 to bring it back to its front position and thus cooperate with the front face of the bolt to eject it from the body 4.

Le déplacement du coulisseau se poursuit tant que celui-ci n'est pas arrivé en butée contre la partie correspondante du corps 4 comme cela a été décrit précédemment.The movement of the slide continues as long as it has not come into abutment against the corresponding part of the body 4 as described above.

Ainsi, les moyens de verrouillage du pène sont constitués par une partie en saillie du corps, cette partie en saillie étant destinée à s'engager dans un évidement du pène, en position de verrouillage de celui-ci. D'autre part, le coulisseau constitue des moyens de maintien de l'évidement du pène, autour de cette saillie ce coulisseau étant monté déplaçable par ledit pène lors de son introduction dans le corps, dans la direction générale de déplacement du pène. Le coulisseau est également sollicité par un organe élas­tique de rappel et coopére en position de verrouillage du pène, avec le corps et une surface correspondante du pène pour maintenir celui-ci en position de ver­rouillage , sous l'action de l'organe élastique de rappel.Thus, the bolt locking means consist of a projecting part of the body, this projecting part being intended to engage in a recess of the bolt, in the locking position of the latter. On the other hand, the slide constitutes means for maintaining the recess of the bolt, around this projection this slide being mounted displaceable by said bolt when it is introduced into the body, in the general direction of movement of the bolt. The slide is also biased by an elastic return member and cooperates in the bolt locking position, with the body and a corresponding surface of the bolt to maintain the latter in the locked position, under the action of the elastic return member. .

D'autre part, le coulisseau est également monté déplaçable dans ledit corps sous l'action des moyens de commande de déverrouillage entre cette posi­tion de maintien et une position de libération du pène dans laquelle il coopère avec des moyens d'éjection pour éjecter ce pène de la boucle. Ces moyens d'éjec­tion sont constitués par l'organe élastique de rappel dont l'une des extrémités est en appui contre le cou­lisseau et,l'autre, contre l'organe de déverrouillage du pène, cet organe de déverrouillage étant articulé sur le corps, pour déverrouiller le pène en dégageant l'évidement de celui-ci de la partie en saillie du corps.On the other hand, the slide is also mounted movable in said body under the action of the unlocking control means between this holding position and a bolt release position in which it cooperates with ejection means to eject this bolt of the loop. These ejection means consist of the elastic return member, one end of which bears against the slide and the other against the bolt unlocking member, this unlocking member being articulated on the body. , to unlock the bolt by releasing the recess therefrom from the protruding part of the body.

Comme on peut le voir sur la Fig.5, les moyens de commande de déverrouillage du pène consti­tués par exemple par des boutons coulissants disposés de part et d'autre du boîtier, peuvent coopérer avec des parties en saillie 7a, 7b du coulisseau, s'éten­dant au-delà du corps 4, pour déplacer celui-ci.As can be seen in Fig.5, the bolt unlocking control means constituted for example by sliding buttons arranged on either side of the housing, can cooperate with projecting parts 7a, 7b of the slide, s 'extending beyond the body 4, to move the latter.

Il est à noter que le ressort 11 est calculé de manière connue en soi pour permettre le dégagement complet de l'évidement du pène, de la partie en sail­lie du corps, avant que l'organe de déverrouillage re­monte dans le corps, ceci afin d'éviter un verrouilla­ge involontaire du pène lors de son éjection de la boucle.It should be noted that the spring 11 is calculated in a manner known per se to allow the complete recess of the recess of the bolt, of the projecting part of the body, before the unlocking member rises in the body, this in order to '' avoid involuntary locking of the bolt when it is ejected from the buckle.

D'autre part, le bossage de guidage 7a du coulisseau peut comporter une partie en saillie coopé­rant avec un organe de déverrouillage coulissant sur l'une des faces du boîtier pour assurer le déplacement de celui-ci et le déverrouillage du pène.On the other hand, the guide boss 7 a of the slide may include a projecting part cooperating with an unlocking member sliding on one of the faces of the housing to ensure the displacement of the latter and the unlocking of the bolt.
