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 connait dans l'état de la technique des boucles comportant un boitier 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 pêne 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 are loops comprising a housing in which is placed a bracket in the form of a stirrup which is intended to be fixed to a fixed retaining means relative to the vehicle body 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 about 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 pêne 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 pêne 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 élas- tique 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 pêne.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 pull on the strap tending to withdraw the bolt from the buckle, this protruding portion cooperates with a stop edge formed in the bottom of the support bracket, optionally by deforming s devel - tick the axis of oscillation of the locking member lage in the stirrup. which allows to obtain a high efficiency of the buckle and a considerable retention 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.Document FR-2,482,430 also discloses a seat belt buckle 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 sliding point 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 augmente les prix de revient de tels dispositifs. 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.The construction of such devices has a certain number of drawbacks, in particular as regards compliance with fairly tight tolerances during manufacture, which increases the cost prices of such devices. 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, par l'intermédiaire d'un péne formant verrou solidaire du brin à fixer, ladite boucle comportant un boitier dans lequel est placé un corps destiné à être fixé à un moyen de retenue solidaire du véhicule et qui définit un passage rectiligne dans lequel peut être introduit le pène et, en outre, un organe de verrouillage destiné à maintenir le pène en position verrouillée et un organe de commande de déverrouillage du pène, caractérisée en ce que l'organe de verrouillage est monté oscillant et déplaçable à coulissement dans ledit corps entre une position de verrouillage dudit pêne et une position de libération de celui-ci et en ce qu'il comporte à ses extrémités des moyens destinés à coopérer avec des surfaces d'arrêt du corps et du pène sous l'action d'un dispositif à franchissement de point mort.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, by means of a bolt forming bolt secured to the strand to be fixed, said loop comprising a box in which is placed a body intended to be fixed to a retaining means secured to the vehicle and which defines a rectilinear passage into which the bolt and, in addition, a member locking device intended to hold the bolt in the locked position and a bolt unlocking control member, characterized in that the locking member is mounted to oscillate and to slide in said body between a locking position of said bolt and a release position thereof and in that it comprises at its ends means intended to cooperate with stop surfaces of the body and of the bolt under the action of a neutral crossing device.

Un organe de commande de déverrouillage 6, comportant une extrémité se présentant sous la forme d'une rampe 7, est disposé à coulissement entre le corps 4 et l'élément supérieur 2 du boitier 1.As shown in Fig 1, a seat belt buckle according to the invention comprises a housing 1 consisting, in a manner known per se, of an upper element 2 and a lower element 3. At the inside this box 1 is disposed a body 4 which is, in longitudinal section, in the general form of an elongated C. A locking member 5, which will be described in more detail below, is housed inside this body 4. A member unlocking control 6, having one end in the form of a ramp 7, is arranged to slide between the body 4 and the upper element 2 of the housing 1.

Ainsi qu'on peut le constater, le boitier 1 comporte une première lumière 8 dans laquelle débouche une extrémité de l'organe de commande de déverrouillage 6 de façon que l'utilisateur de la boucle de ceinture de sécurité ait accès à cet organe 6.As can be seen, the housing 1 includes a first lumen 8 into which opens one end of the unlocking control member 6 so that the user of the seat belt buckle has access to this member 6.

Le boitier 1 comporte également une première ouverture 9, dont les parois sont inclinées, débouchant dans un orifice 10 ménagé dans le corps 4. Comme nous le verrons par la suite, cette ouverture 9 et cet orifice 10 définissent un passage pour par exemple une languette formant pène solidaire d'un brin à fixer de la ceinture de sécurité.The housing 1 also has a first opening 9, the walls of which are inclined, opening into an orifice 10 formed in the body 4. As we will see later, this opening 9 and this orifice 10 define a passage for for example a tongue forming bolt secured to a strand to be attached to the seat belt.

Le boitier 1 comporte également une seconde ouverture 11 ménagée dans l'extrémité du boitier 1 opposée à l'extrémité dans laquelle est pratiquée l'ouverture 9. Cette ouverture 11 est ménagée en regard des extrémités de deux parois constituant le corps 4. Cette ouverture 11 est destinée 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 de façon à rendre solidaire le corps 4, du véhicule.The case 1 also includes a second opening 11 formed in the end of the case 1 opposite the end in which the opening 9 is made. This opening 11 is formed opposite the ends of two walls constituting the body 4. This opening 11 is intended 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 so as to make the body 4 integral with the vehicle.

Comme représenté Fig.la, des extrémités des deux parois constituant un corps 4a peuvent faire saillie au dehors d'un boitier 1a, à travers une ouverture 11a ménagée dans l'extrémité du boitier 1a opposée à l'extrémité dans laquelle est pratiquée une ouverture permettant l'introduction du pêne dans la boucle.As shown in FIG. 1a, the ends of the two walls constituting a body 4a can protrude outside a box 1a, through an opening 11a formed in the end of the box 1a opposite the end in which an opening is made allowing the introduction of the bolt in the loop.

Ces extrémités sont pourvues d'évidements 4b destinés à permettre la fixation du corps 4a sur un moyen de retenue solidaire du véhicule.These ends are provided with recesses 4b intended to allow the attachment of the body 4a to a retaining means secured to the 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.

L'organe de verrouillage 5 comporte quant à lui une première saillie 12 qui, dans la position représentée sur la Fig. 1, s'étend à travers une lumière 13 ménagée dans la paroi supérieure du corps 4 en re-gard de l'organe de commande de déverrouillage 6. Dans cette position, la première saillie 12 est donc disposée au-dessus du passage défini par l'ouverture 9 du boitier 1 et l'orifice 10 du corps 4. Cet organe de verrouillage comporte, à son autre extrémité, une se-conde saillie 14 qui dans la position représentée sur cette figure, est en appui contre un bord de la paroi supérieure du corps 4. Cette extrémité de l'organe de verrouillage 5 comporte également un téton de centrage 15 sur lequel est disposée une extrémité d'un dispositif à franchissement de point mort qui peut être constitué par exemple par un ressort 16, dont l'autre extrémité prend appui sur un téton 17 formé dans la paroi inférieure du corps 4, et qui est incliné vers l'intérieur de celui-ci, par rapport à la direction du déplacement de l'organe de verrouillage à l'intérieur du corps 4, comme on le verra par la suite.The locking member 5 has a first projection 12 which, in the position shown in FIG. 1, extends through a slot 13 formed in the upper wall of the body 4 in re-gard of the unlocking control member 6. In this position, the first projection 12 is therefore disposed above the passage defined by the opening 9 of the housing 1 and the orifice 10 of the body 4. This locking member comprises, at its other end, a second protrusion 14 which, in the position shown in this figure, bears against an edge of the upper wall of the body 4. This end of the locking member 5 also comprises a centering pin 15 on which is disposed one end of a device for crossing neutral point which can be constituted for example by a spring 16, the l 'other end is supported on a stud 17 formed in the lower wall of the body 4, and which is inclined towards the inside thereof, relative to the direction of movement of the locking member inside the body 4, as will be seen later.

Ce ressort 16 exerce une force qui tend à maintenir la seconde saillie 14 de l'organe de verrouillage 5 contre la paroi supérieure du corps 4 et à pousser cet organe 5 pour que la première saillie 12 de celui-ci vienne en appui contre un rebord de la lumière 13.This spring 16 exerts a force which tends to hold the second projection 14 of the locking member 5 against the upper wall of the body 4 and to push this member 5 so that the first projection 12 thereof comes to bear against a flange light 13.

Dans sa partie centrale, l'organe de verrouillage 5 comporte deux ailes formées par emboutissage et venues de matière avec le reste de l'organe de verrouillage, dont une seule, 18, est représentée et dans lesquelles est disposé un axe 19 qui, comme nous le verrons par la suite, peut être un axe rapporté dans les ailes de l'organe de verrouillage 5 ou un axe venant de matière avec celles-ci.In its central part, the locking member 5 comprises two wings formed by stamping sage and comings of matter with the rest of the locking member, of which only one, 18, is shown and in which is disposed an axis 19 which, as we will see later, may be an axis added in the wings of the locking member 5 or an axis coming integrally therewith.

Les extrémités de cet axe 19, s'étendant latéralement au-delà des ailes de l'organe de verrouillage, reposent sur des rebords d'une lumière -20 ména-gée dans la paroi inférieure du corps 4.The ends of this axis 19, extending laterally beyond the wings of the locking member, rest on the edges of a lumen -20 mena-ged in the lower wall of the body 4.

Ainsi qu'il sera décrit plus en détail par la suite l'organe de verrouillage 5 est monté oscillant autour de cet axe 19 et déplaçable à coulissement dans le corps 4.As will be described in more detail below, the locking member 5 is mounted oscillating around this axis 19 and movable by sliding in the body 4.

Lorsque l'on introduit. une languette formant pêne 21 (Fig. 2), comportant un évidement 22, dans l'ouverture 9 ménagée dans le boitier et l'orifice 10 du corps 4, l'extrémité de celle-ci vient en appui contre les ailes, par exemple 18, de l'organe de verrouillage 5 et si l'utilisateur exerce une pression sur ce pène de façon à l'introduire dans la boucle de ceinture de sécurité, l'organe de verrouillage 5 est repoussé dans le corps 4. Ces ailes constituent donc des moyens d'appui pour l'extrémité du pêne, en vue du déplacement à coulissement par celui-ci, de l'organe de verrouillage. Ce déplacement est possible en raison du fait que l'organe de verrouillage est monté déplaçable à coulissement dans le corps 4 à l'encontre de l'action de l'organe élastique du dispositif à franchissement de point mort constitué par le ressort 16. Pour un certain déplacement de l'organe de verrouillage 5, la saillie 14 de celui-ci va se trouver en re- gard d'une lumière 23 ménagée dans la paroi supérieure du corps 4 et définissant un bord de celle-ci. Le ressort 16 et éventuellement un rebord 24 du corps 4 formé sensiblement en regard des ailes de l'organe de verrouillage 5, vont alors amener l'organe de verrouillage à se déplacer angulairement autour de son axe 19 reposant sur la paroi inférieure du corps 4.When we introduce. a tongue forming a bolt 21 (FIG. 2), comprising a recess 22, in the opening 9 formed in the housing and the orifice 10 of the body 4, the end of the latter bears against the wings, for example 18, of the locking member 5 and if the user exerts a pressure on this bolt so as to introduce it into the seat belt buckle, the locking member 5 is pushed back into the body 4. These wings constitute therefore support means for the end of the bolt, for sliding movement by the latter, of the locking member. This movement is possible due to the fact that the locking member is mounted to slide in the body 4 against movement by the elastic member of the neutral point crossing device constituted by the spring 16. For a certain displacement of the locking member 5, the projection 14 thereof will be in relation to a lumen 23 formed in the upper wall of the body 4 and defining an edge thereof. The spring 16 and possibly a flange 24 of the body 4 formed substantially opposite the wings of the locking member 5, will then cause the locking member to move angularly about its axis 19 resting on the bottom wall of the body 4.

Lorsque ce déplacement angulaire est suffisant pour que le dispositif à franchissement de point mort, constitué par le ressort 16, dépasse son point mort, celui-ci va imprimer un mouvement de basculement (Fig. 3) à l'organe de verrouillage 5. La saillie 14 de celui-ci va alors pénétrer dans la lumière 23 du corps 4 et la saillie 12 de cet organe de verrouillage va traverser l'évidement 22 du pène 21 et venir en appui contre un rebord de la lumière 20.When this angular displacement is sufficient for the neutral point crossing device, constituted by the spring 16, to exceed its neutral point, the latter will impart a rocking movement (FIG. 3) to the locking member 5. The projection 14 of the latter will then penetrate into the lumen 23 of the body 4 and the projection 12 of this locking member will pass through the recess 22 of the bolt 21 and come to bear against a flange of the lumen 20.

Si le déplacement à coulissement de l'organe de verrouillage 5 se poursuit c'est-à-dire si l'utilisateur poursuit son action sur le pène 21, la saillie 12 de l'organe de verrouillage pénètre dans la lumière 20 du corps 4 sous l'action du ressort 16. Dans cette position, représentée sur la Fig. 4, la saillie 14 de l'organe de verrouillage 5 s'étend au-delà de la paroi supérieure du corps 4 et lorsque l'utilisateur relâche sa pression sur le pène 21, l'organe de verrouillage 5 est ramené, sous l'effet de l'action du ressort 16, dans une position stable dans laquelle la saillie 12 s'étend à travers l'évidement 22 du pène 21 et est en appui contre un bord d'arrêt de la lumière 20 du corps 4, assurant ainsi un verrouillage du pène dans la boucle.If the sliding movement of the locking member 5 continues, that is to say if the user continues to act on the bolt 21, the projection 12 of the locking member enters the lumen 20 of the body 4 under the action of the spring 16. In this position, shown in FIG. 4, the projection 14 of the locking member 5 extends beyond the upper wall of the body 4 and when the user releases his pressure on the bolt 21, the locking member 5 is brought back under the effect of the action of the spring 16, in a stable position in which the projection 12 extends through the recess 22 of the bolt 21 and is in abutment against a light stop edge 20 of the body 4, thus ensuring locking the bolt in the loop.

Le déplacement de l'organe de verrouillage à l'intérieur du corps 4 est limité d'une part par l'appui de la saillie 12 sur le bord d'arrêt de la lumière 20 et d'autre part par la saillie 14 venant en appui contre une paroi de la lumière 23.The movement of the locking member inside the body 4 is limited on the one hand by the support of the projection 12 on the light stop edge 20 and on the other hand by the projection 14 coming in support against a wall of the light 23.

Lorsque l'utilisateur désire déverrouiller la boucle de ceinture de sécurité, il agit, comme illustré par la flèche F sur la Fig.4, sur l'organe de commande de déverrouillage 6 de façon à lui imprimer un mouvement de coulissement qui amène la rampe 7 de celui-ci en appui contre la saillie 14 de l'organe de verrouillage, de façon que l'organe de verrouillage 5 soit amené à se déplacer angulairement autour de l'axe 19 pour que la saillie 12 de l'organe 5 se dégage de la lumière 20 et que, sous l'action du ressort 16, l'organe de verrouillage soit amené à basculer et à se déplacer à coulissement vers la position représentée sur la Fig.1, dans laquelle la saillie 12 est également dégagée de l'évidement 22 du pêne 21.When the user wishes to unlock the seat belt buckle, he acts, as illustrated by the arrow F in FIG. 4, on the unlocking control member 6 so as to impart to him a sliding movement which brings the ramp 7 thereof bearing against the projection 14 of the locking member, so that the locking member 5 is caused to move angularly around the axis 19 so that the projection 12 of the member 5 is releases light 20 and that, under the action of spring 16, the locking member is caused to tilt and slide to move to the position shown in Fig.1, in which the projection 12 is also released from the recess 22 of the bolt 21.

Durant ce déplacement, les ailes 18 de l'organe de verrouillage 5 poussent l'extrémité du pène 21 de sorte que celui-ci est éjecté de la boucle de ceinture de sécurité.During this movement, the wings 18 of the locking member 5 push the end of the bolt 21 so that it is ejected from the seat belt buckle.

Il est à noter que l'organe de commande de déverrouillage 6 est muni d'un ressort de rappel (non représenté) qui tend à le ramener en position de repos comme il est représenté sur la Fig. 1.It should be noted that the unlocking control member 6 is provided with a return spring (not shown) which tends to return it to the rest position as shown in FIG. 1.

La saillie .12 assurant la retenue du pène à l'intérieur de la boucle est soumise à un effort de cisaillement lorsqu'une traction est exercée sur le pène 21. Cette saillie 12 doit donc être suffisante pour supporter des efforts importants comme il est de règle en la matière. Aussi, différentes possibilités de fabrication de l'organe de verrouillage peuvent être envisagées.The projection .12 ensuring the retention of the bolt inside the loop is subjected to a shearing force when a traction is exerted on the bolt 21. This projection 12 must therefore be sufficient to withstand significant forces as is rule in the matter. Also, different possibilities of manufacturing the locking member can be envisaged.

Comme il est représenté sur la Fig. 5, un organe de verrouillage 5a peut être réalisé en tôle de faible épaisseur emboutie dans lequel un axe 19a est rapporté. Dans ce cas et comme il a été représenté sur les figures précédentes, l'une des extrémités de cet organe présente une saillie 12a assurant le verrouillage du pène, qui est doublée de façon à présenter une résistance suffisante au cisaillement. Des ailes 18a de l'organe de verrouillage présentent deux évidements dans lesquels est disposé l'axe 19a. Cet axe 19a peut être monté à force dans les évidements des ailes 18a de façon qu'il soit solidaire du reste de l'organe de verrouillage ou il peut être libre à rotation dans ces évidements si il est guidé latéralement dans le corps 4. L'autre extrémité de l'organe de verrouillage 5a présentant une saillie 14a est munie d'une lumière 25 dans laquelle fait saillie un téton 15a de réception d'une extrémité du dispositif à franchissement de point mort de façon analogue au mode de réalisation décrit en regard des Fig. 1 à 4.As shown in FIG. 5, a locking member 5a can be made of pressed sheet metal of small thickness in which an axis 19a is attached. In this case and as shown in the previous figures, one of the ends of this member has a projection 12a ensuring the locking of the bolt, which is doubled so as to have sufficient resistance to shearing. Wings 18a of the locking member have two recesses in which the axis 19a is arranged. This axis 19a can be force-fitted into the recesses of the wings 18a so that it is integral with the rest of the locking member or it can be free to rotate in these recesses if it is guided laterally in the body 4. L 'other end of the locking member 5a having a projection 14a is provided with a slot 25 in which protrudes a stud 15a for receiving one end of the neutral crossing device in a similar manner to the embodiment described in look at Figs. 1 to 4.

D'autre part, et comme il est représenté sur la Fig. 6, l'organe de verrouillage peut se présenter sous la forme d'une pièce emboutie 30 en tôle épaisse dont une saillie 31 assurant la retenue du pène dans la boucle de ceinture de sécurité n'est pas doublée. Une saillie 32, une lumière 33 et un téton 34 présentent des formes analogues aux saillies 14 et 14a, à la lumière 25 et aux tétons 15 et 15a respectivement des modes de réalisation précédents. Ces éléments remplissant le même rôle que les éléments correspondants déjà décrits.On the other hand, and as shown in FIG. 6, the locking member can be in the form of a deep-drawn piece 30 made of thick sheet metal, a projection 31 ensuring the retention of the bolt in the seat belt buckle is not doubled. A projection 32, a lumen 33 and a stud 34 have shapes similar to the projections 14 and 14a, the lumen 25 and the studs 15 and 15a respectively of the previous embodiments. These elements fulfilling the same role as the corresponding elements already described.

Cet organe de verrouillage 30 comporte également des ailes 35 qui sont réalisées en tôle plus épaisse que précédemment. Il est donc possible de réaliser, venant de matière avec ces ailes 35, des parties en saillie 36 remplissant le même rôle que les extrémités des axes 19 et 19A, c'est-à-dire venant en appui sur la paroi inférieure du corps 4 de façon à permettre un mouvement de basculement et de déplacement à coulissement de l'organe de verrouillage 30 dans ce corps 4. Dans ce mode de réalisation, les parties en saillie 36 peuvent avantageusement être de section polygonale.This locking member 30 also includes wings 35 which are made of thicker sheet metal than previously. It is therefore possible to produce, from material with these wings 35, projecting parts 36 fulfilling the same role as the ends of the axes 19 and 19A, that is to say coming to bear on the lower wall of the body 4 so that allow a tilting movement and sliding movement of the locking member 30 in this body 4. In this embodiment, the projecting parts 36 may advantageously be of polygonal section.

On a représenté sur la Fig. 7 un mode de réalisation d'un corps 40 entrant dans la constitution d'une boucle de ceinture de sécurité selon l'invention. Ce corps 40 se présente sous la forme d'un étrier embouti dans une plaque métallique comportant une paroi inférieure 40.& dans laquelle sont pratiqués une lumière 41, analogue à la lumière 20 représentée sur les Fig. 1 à 4, et un évidement 42 au moyen duquel le corps 40 est fixé à un moyen de retenue solidaire du véhicule. Ce corps 40 comporte également deux parois latérales dont une seule, 43, est représentée et dans laquelle est formé par emboutissage un rebord 44 définissant un passage pour le pène.There is shown in FIG. 7 an embodiment of a body 40 forming part of a seat belt buckle according to the invention. This body 40 is in the form of a stirrup stamped in a metal plate having a bottom wall 40. & in which are formed a light 41, analogous to the light 20 shown in FIGS. 1 to 4, and a recess 42 by means of which the body 40 is fixed to a retaining means secured to the vehicle. This body 40 also comprises two side walls of which only one, 43, is shown and in which is formed by stamping a flange 44 defining a passage for the bolt.

Une languette 45 s'étend sensiblement perpendiculairement à la paroi latérale 43, de manière à constituer une paroi supérieure du corps dont les bords remplissent le même rôle que les lumières 13 et 23 représentées sur les Fig. 1 à 4.A tongue 45 extends substantially perpendicular to the side wall 43, so as to constitute an upper wall of the body whose edges fulfill the same role as the slots 13 and 23 shown in FIGS. 1 to 4.

Dans la paroi latérale 43 est également réalisé par emboutissage un rebord 46 faisant saillie vers l'intérieur du corps et destiné à constituer une butée pour les ailes de l'organe de verrouillage de manière à limiter son mouvement de déplacement vers l'avant sous l'action du ressort 16. En effet, le corps 40 ne comporte pas de surface d'appui pour la saillie assurant le verrouillage du pène, lorsque celui-ci se trouve en position déverrouillée et il est donc nécessaire de prévoir des moyens pour limiter son déplacement vers l'avant.In the side wall 43 is also produced by stamping a flange 46 projecting towards the inside of the body and intended to constitute a stop for the wings of the locking member so as to limit its movement of movement forwards under the action of the spring 16. In fact, the body 40 does not have a bearing surface for the projection ensuring the locking of the bolt, when the latter is in the unlocked position and it is therefore necessary to provide means for limiting its moving forward.

Un téton 47, destiné à recevoir une extrémité du dispositif à franchissement de point mort, s'étend dans la lumière 41.A stud 47, intended to receive one end of the device passing through neutral, extends into the lumen 41.

Ce téton 47 est également incliné vers l'intérieur du corps 40 par rapport à la direction de déplacement de l'organe de verrouillage dans ledit corps.This stud 47 is also inclined towards the inside of the body 40 relative to the direction of movement of the locking member in said body.
