Description

L'invention concerne en général les ouvrants de véhicules automobiles, et les dispositifs de sécurité empêchant l'ouverture de ces ouvrants en cas de chocs.The invention generally relates to the opening of motor vehicles, and the safety devices preventing the opening of these openings in case of shocks.

Plus précisément, l'invention concerne selon un premier aspect un dispositif d'ouverture d'un ouvrant de véhicule automobile, ce dispositif comprenant une poignée actionnable manuellement montée d'un côté extérieur de l'ouvrant, un organe de renvoi déplacé d'une position normale à une position d'ouverture quand la poignée est actionnée, et des moyens de verrouillage adoptant sélectivement des configurations de verrouillage de l'ouvrant sur la structure du véhicule ou de déverrouillage, ces moyens coopérant normalement avec l'organe de renvoi et adoptant leur configuration de déverrouillage quand cet organe passe de sa position de repos à sa position d'ouverture , ce dispositif comprenant encore un organe de sécurité adoptant par inertie en cas de choc sur l'ouvrant une position d'interdiction interdisant le déplacement de l'organe de renvoi vers sa position d'ouverture.More precisely, the invention relates, according to a first aspect, to a device for opening a motor vehicle door, this device comprising a manually actuable handle mounted on an outer side of the door, a return member displaced from an normal position to an open position when the handle is actuated, and locking means selectively adopting configurations of the opening of the opening on the vehicle structure or unlocking, these means cooperating normally with the return member and adopting their unlocking configuration when this member passes from its rest position to its open position, this device further comprising a safety member adopting by inertia in the event of impact on the opening a prohibition position prohibiting the movement of the return member to its open position.

Des dispositifs de ce type sont connus de l'art antérieur, et comportent typiquement des organes de sécurités constitués d'une masselotte qui se met en mouvement par inertie en cas de choc avant la poignée, et vient bloquer l'organe de renvoi avant que celui-ci ne déclenche le déverrouillage de l'ouvrant.Devices of this type are known from the prior art, and typically comprise safety devices consisting of a flyweight which is moved by inertia in case of impact before the handle, and blocks the return member before it does not trigger the unlocking of the opening.

Ces dispositifs, dans certains cas, ne parviennent pas à bloquer le déverrouillage de l'ouvrant à cause du phénomène de rebond décalé, illustré sur la figure 3.These devices, in some cases, fail to block the unlocking of the opening because of the rebound rebound phenomenon, illustrated in FIG.

En effet, les différents éléments constituant le dispositif d'ouverture présentent des formes et des rigidités différentes, et subissent des types de déformations différentes pendant un choc sur l'ouvrant. Ils ne réagissent donc pas de façon homogène en cas de choc, et il peut se produire des phénomènes d'accélérations et de décélérations décalées temporellement entre ces différents éléments. En
Le document US-A-6042159 décrit un dispositif d'ouverture d'un ouvrant selon le préambule de la revendication 1. particulier, quand le dispositif de sécurité et la poignée subissent des accélérations décalées temporellement, ce décalage peut conduire au déverrouillage et à l'ouverture de l'ouvrant.Indeed, the various elements constituting the opening device have different shapes and rigidities, and undergo different types of deformations during an impact on the opening. They therefore do not react homogeneously in the event of shock, and there can be phenomena of accelerations and decelerations temporally offset between these different elements. In
The document US Patent 6042159 discloses an opening device of an opening according to the preamble of claim 1. Particularly, when the safety device and the handle undergo temporally offset accelerations, this offset can lead to the unlocking and opening of the opening.

Ce phénomène a été constaté au cours d'essais de chocs, comme le montre la figure 3 . Celle-ci est une représentation graphique de l'évolution en fonction du temps du déplacement de la poignée (courbe P en traits continus), du déplacement de l'organe de sécurité (courbe S en traits mixtes) et du contact entre le pêne et la gâche des moyens de verrouillage de l'ouvrant sur le véhicule (courbe tout ou rien C en traits mixtes).This phenomenon was found during shock tests, as shown in Figure 3. This is a graphical representation of the evolution as a function of time of the movement of the handle (curve P in continuous lines), the displacement of the safety member (curve S in phantom lines) and the contact between the bolt and the lock of the locking means of the opening on the vehicle (all-or-nothing curve C in phantom).

Dans la zone I, on voit que l'organe de sécurité se déplace avant la poignée et empêche donc le déverrouillage de l'ouvrant.In zone I, we see that the safety member moves before the handle and thus prevents unlocking of the opening.

Dans la zone II, l'organe de sécurité subit un second déplacement de plus grande ampleur que le premier, qui précède celui de la poignée, et bloque donc cette poignée dans un premier temps. Puis il revient vers sa position de repos (partie descendante du pic), ce qui a pour effet de libérer la poignée.In zone II, the safety member undergoes a second displacement of greater magnitude than the first, which precedes that of the handle, and therefore blocks this handle at first. Then it returns to its rest position (descending portion of the peak), which has the effect of releasing the handle.

On voit en effet dans la zone III que les déplacements de l'organe de sécurité et de la poignée sont concomitants, et que le déplacement de la poignée n'est pas bloqué par l'organe de sécurité. Ceci est confirmé par le contact entre le pêne et la gâche, qui n'est plus réalisé à partir de 0,021 secondes, c'est-à-dire du sommet du troisième pic de déplacement de l'organe de sécurité. Le déplacement de la poignée atteint 10 millimètres, ce qui correspond au déverrouillage de l'ouvrant.It can be seen in zone III that the movements of the safety member and the handle are concomitant, and that the movement of the handle is not blocked by the safety member. This is confirmed by the contact between the bolt and the strike, which is no longer performed from 0.021 seconds, that is to say from the top of the third peak of movement of the safety member. The movement of the handle reaches 10 millimeters, which corresponds to the unlocking of the opening.

Par ailleurs, lors d'essais d'impact latéral sur un ouvrant latéral muni d'une poignée de type valise, il a été observé que la barrière de choc, en se retirant après l'impact, pouvait actionner la poignée et déverrouiller l'ouvrant.Furthermore, during lateral impact tests on a side opening with a suitcase type handle, it was observed that the shock barrier, by withdrawing after the impact, could actuate the handle and unlock the door. opening.

L'invention vis également à résoudre ce problème.The invention also aims to solve this problem.

Dans ce contexte, la présente invention a pour but de pallier le problème mentionné ci-dessus, et de proposer un dispositif d'ouverture qui ne conduit pas au déverrouillage de l'ouvrant, même en cas de rebonds décalés des différents éléments le constituant.In this context, the present invention aims to overcome the problem mentioned above, and to provide an opening device that does not lead to the unlocking of the opening, even in case of offset rebounds of the various elements constituting it.

A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que qu'il comprend des moyens pour bloquer l'organe de sécurité dans sa position d'interdiction.To this end, the device of the invention, furthermore in accordance with the generic definition given in the preamble above, is essentially characterized in that it comprises means for locking the safety member in its position. ban.

Selon l'invention, le dispositif comprend un étrier de support rigidement fixé à l'intérieur de l'ouvrant, l'organe de sécurité étant monté à rotation sur l'étrier autour d'un premier axe et passant d'une position de repos à sa position d'interdiction par rotation autour ce premier axe.According to the invention, the device comprises a support bracket rigidly fixed inside the opening, the safety member being rotatably mounted on the stirrup about a first axis and passing from a rest position. at its position of prohibition by rotation around this first axis.

Selon l'invention les moyens de blocage de l'organe de sécurité comprennent une languette souple solidaire de l'étrier ou de l'organe de renvoi, et au moins un relief ménagé sur l'organe de sécurité coopérant avec la languette souple en position d'interdiction de l'organe de sécurité pour bloquer la rotation de celui-ci vers sa position de repos.According to the invention, the locking means of the safety member comprise a flexible tongue integral with the stirrup or the return member, and at least one relief formed on the safety member cooperating with the flexible tongue in position. prohibiting the safety member to block the rotation thereof to its rest position.

Dans un premier mode de réalisation de l'invention, l'organe de sécurité comprend une masselotte, cette masselotte présentant un bord radialement extérieur décrivant une trajectoire en arc de cercle autour de l'axe de rotation quand l'organe de sécurité passe de sa position de repos à sa position d'interdiction, la languette s'étendant à partir de l'étrier jusqu'à une extrémité libre suivant une direction tangente à une zone de ladite trajectoire en arc de cercle occupée par le bord extérieur en position d'interdiction, ou légèrement inclinée par rapport à ladite tangente .In a first embodiment of the invention, the safety member comprises a flyweight, this flyweight having a radially outer edge describing a trajectory in an arc around the axis of rotation when the safety member passes from its rest position at its prohibited position, the tab extending from the stirrup to a free end in a direction tangent to an area of said arcuate trajectory occupied by the outer edge in position of prohibition, or slightly inclined with respect to said tangent.

Dans ce cas, l'extrémité libre de la languette peut occuper ladite zone de la trajectoire en arc de cercle, le relief étant une concavité creusée dans le bord extérieur de la masselotte.In this case, the free end of the tongue can occupy said zone of the trajectory in an arc of circle, the relief being a concavity dug in the outer edge of the weight.

De plus, la languette peut s'étendre à partir de l'étrier vers l'extrémité libre dans un sens correspondant au sens de rotation de la masselotte.In addition, the tongue can extend from the yoke to the free end in a direction corresponding to the direction of rotation of the weight.

Dans un second mode de réalisation de l'invention, quand l'organe de sécurité est en position d'interdiction, l'organe de renvoi vient en butée contre un bras de l'organe de sécurité dans son mouvement de sa position normale vers sa position d'ouverture, la languette souple étant portée par l'organe de renvoi, la languette et le bras étant conformés de façon à s'imbriquer irréversiblement l'un avec l'autre quand l'organe de renvoi est en butée de façon à bloquer la rotation de l'organe de sécurité par rapport à l'organe de renvoi .In a second embodiment of the invention, when the safety member is in the prohibited position, the return member abuts against an arm of the safety member in its movement from its normal position to its position. opening position, the flexible tongue being carried by the return member, the tongue and the arm being shaped so as to interlock irreversibly with each other when the return member is in abutment so as to block the rotation of the safety member relative to the return member.

Dans ce cas, quand l'organe de renvoi est en butée sur le bras de blocage, la languette peut être accolée le long de ce bras, le bras et la languette présentant des creux et des parties en saillie complémentaires qui s'interpénètrent et bloquent le bras en rotation par rapport à l'organe de renvoi.In this case, when the return member is in abutment on the locking arm, the tongue can be contiguous along the arm, the arm and the tongue having recesses and complementary projecting parts which interpenetrate and block the arm in rotation with respect to the return member.

Avantageusement, l'organe de renvoi peut être un axe parallèle au premier axe, monté à rotation sur l'étrier, venant en butée sur le bras de blocage par l'intermédiaire d'un doigt d'actionnement qui porte la languette.Advantageously, the return member may be an axis parallel to the first axis, rotatably mounted on the yoke, abutting the locking arm by means of an actuating finger which carries the tongue.

Enfin, le dispositif peut comprendre un écran amovible interposé entre la languette souple et le relief.Finally, the device may comprise a removable screen interposed between the flexible tongue and the relief.

Le dispositif représenté sur la figure 1 est adapté à l'ouverture d'un ouvrant 1 de véhicule automobile délimité d'un côté extérieur par une peau 101, notamment à un ouvrant latéral.The device shown in Figure 1 is adapted to the opening of an opening 1 of a motor vehicle bounded on an outer side by a skin 101, in particular to a side opening.

Ce dispositif 2 comprend une poignée 10 actionnable manuellement montée d'un côté extérieur de la peau 101 de l'ouvrant, un organe de renvoi 20 déplacé d'une position normale à une position d'ouverture quand la poignée 10 est actionnée, et des moyens de verrouillage adoptant sélectivement des configurations de verrouillage de l'ouvrant 1 sur la structure du véhicule ou de déverrouillage de cet ouvrant par rapport à la structure du véhicule, l'ouvrant 1 étant susceptible de s'ouvrir dans la configuration de déverrouillage .This device 2 comprises a manually operable handle 10 mounted on an outer side of the skin 101 of the opening, a return member 20 moved from a normal position to an open position when the handle 10 is actuated, and locking means selectively adopting locking configurations of the opening 1 on the vehicle structure or unlocking of this opening relative to the vehicle structure, the opening 1 being capable of opening in the unlocking configuration.

Les moyens de verrouillage coopèrent normalement avec l'organe de renvoi 20 et adoptent leur configuration de déverrouillage quand cet organe passe de sa position de repos à sa position d'ouverture.The locking means normally cooperate with the return member 20 and adopt their unlocking configuration when the member moves from its rest position to its open position.

Les moyens de verrouillage sont connus et ne seront donc pas décrits ici.The locking means are known and will not be described here.

Le dispositif d'ouverture 2 comprend encore un organe de sécurité 30 adoptant par inertie, en cas de choc sur l'ouvrant 1 suivant une direction sensiblement perpendiculaire à cet ouvrant, une position d'interdiction interdisant le déplacement de l'organe de renvoi 20 vers sa position d'ouverture.The opening device 2 further comprises a safety member 30 adopting by inertia, in the event of impact on the opening 1 in a direction substantially perpendicular to this opening, a prohibition position prohibiting the displacement of the return member 20 towards its open position.

L'organe de renvoi 20, les moyens de verrouillage et l'organe de sécurité 30 sont disposés à l'intérieur de l'ouvrant 1.The deflection member 20, the locking means and the safety member 30 are arranged inside the opening 1.

Selon l'invention, le dispositif d'ouverture 2 comprend des moyens 40 pour bloquer l'organe de sécurité 30 dans sa position d'interdiction.According to the invention, the opening device 2 comprises means 40 for locking the safety member 30 in its prohibited position.

Ainsi, quand se produit un choc sur l'ouvrant 1, l'organe de sécurité 30 est déplacé dès le début du choc vers sa position d'interdiction, avant que l'organe de renvoi 20 adopte sa position d'ouverture sous l'effet du déplacement de la poignée 10 dû au choc. L'organe de sécurité 30 est ensuite maintenu dans cette position pendant toute la durée du choc, de telle sorte que, quels que soient les mouvements des autres éléments du dispositif d'ouverture, l'organe de renvoi ne peut jamais adopter sa position d'ouverture et l'ouvrant ne peut pas être déverrouillé.Thus, when a shock occurs on the opening 1, the safety member 30 is moved from the beginning of the shock to its prohibited position, before the return member 20 adopts its open position under the effect of the displacement of the handle 10 due to the shock. The safety member 30 is then held in this position for the duration of the impact, so that, regardless of the movements of the other elements of the opening device, the return member can never adopt its position d opening and the opening can not be unlocked.

Plus précisément, le dispositif d'ouverture 2 comprend un étrier de support 50 présentant une forme allongée longitudinalement, rigidement fixé à l'intérieur de l'ouvrant 1.More specifically, the opening device 2 comprises a support bracket 50 having a longitudinally elongate shape, rigidly fixed inside the opening 1.

La poignée 10 comprend un organe de préhension 11 monté mobile par rapport à l'ouvrant 10 d'un côté extérieur de la peau 101, et un organe d'actionnement 12 de l'organe de renvoi 20 solidaire de l'organe de préhension 11 et s'étendant à l'intérieur de l'ouvrant 1. L'organe de préhension 11 présente par exemple une forme allongée suivant l'axe longitudinal du véhicule , et est articulé autour d'un axe vertical par une extrémité longitudinale arrière sur une extrémité longitudinale arrière correspondante de l'étrier 50.The handle 10 comprises a gripping member 11 movably mounted relative to the opening 10 of an outer side of the skin 101, and an actuating member 12 of the return member 20 secured to the gripping member 11 and extending inside the opening 1. The gripping member 11 has for example an elongate shape along the longitudinal axis of the vehicle, and is articulated about a vertical axis by a rear longitudinal end on a corresponding longitudinal longitudinal end of the stirrup 50.

L'organe d'actionnement 12 s'étend sensiblement transversalement à partir d'une extrémité avant de l'organe de préhension 11 opposée à l'axe vertical, vers l'intérieur de l'ouvrant. Cet organe traverse la peau 101 par une ouverture ménagée à cet effet.The actuating member 12 extends substantially transversely from a front end of the gripping member 11 opposite the vertical axis, towards the inside of the opening. This body passes through the skin 101 through an opening provided for this purpose.

L'organe de renvoi 20 est un axe sensiblement vertical, monté à rotation sur l'étrier 50. Il comprend un voile 21 s'étendant sensiblement longitudinalement, vers l'avant du véhicule. L'organe d'actionnement 12 est disposé devant l'organe de renvoi 20, et comprend une partie en saillie vers l'arrière portée par une extrémité libre dudit organe opposée à l'organe de préhension 11.The deflection member 20 is a substantially vertical axis rotatably mounted on the yoke 50. It comprises a web 21 extending substantially longitudinally towards the front of the vehicle. The actuating member 12 is disposed in front of the deflection member 20, and comprises a rearward projecting portion carried by a free end of said member opposite to the gripping member 11.

La poignée 10 est actionnée par rotation de l'organe de préhension 11 vers l'extérieur autour de l'axe vertical, ce dont il résulte que l'organe d'actionnement 12 se déplace vers l'extérieur, la partie en saillie venant porter contre le voile 21 et entraînant l'organe de renvoi 20 en rotation de sa position normale à sa position d'ouverture. L'organe de renvoi 20 occupe sa position normale notamment quand l'ouvrant 1 est verrouillé sur la structure du véhicule et que la poignée 10 n'est pas actionnée.The handle 10 is actuated by rotation of the gripping member 11 towards the outside about the vertical axis, which results in the actuating member 12 moving outwards, the projecting portion coming to bear against the sail 21 and causing the return member 20 to rotate from its normal position to its open position. The return member 20 occupies its normal position, in particular when the opening 1 is locked on the structure of the vehicle and the handle 10 is not actuated.

L'organe de renvoi 20 comprend par ailleurs un doigt d'actionnement 22 sensiblement radial, s'étendant en oblique vers l'arrière et vers l'extérieur en position normale, ce doigt permettant de faire passer les moyens de verrouillage de leur configuration de verrouillage à leur configuration de déverrouillage, par pivotement quand l'organe de renvoi 20 passe de sa position normale à sa position d'ouverture.The deflection member 20 furthermore comprises a substantially radial actuating finger 22 extending obliquely rearwardly and outwardly in a normal position, this finger making it possible to pass the locking means from their configuration of locking to their unlocking configuration, by pivoting when the return member 20 moves from its normal position to its open position.

L'organe de sécurité 30 est monté à rotation sur l'étrier 50 autour d'un premier axe 31 vertical, et passe d'une position de repos à sa position d'interdiction par rotation autour ce premier axe 31. L'axe 31 est décalé vers l'arrière par rapport à l'organe de renvoi 20.The safety member 30 is rotatably mounted on the stirrup 50 about a first vertical axis 31, and moves from a rest position to its prohibition position by rotation about this first axis 31. The axis 31 is shifted rearwardly with respect to the return member 20.

Il comprend une masselotte 32, par exemple de forme parallélépipédique, un voile de liaison 33 s'étendant sensiblement radialement à partir du premier axe 31 et solidarisant cet axe à un bord radialement intérieur de la masselotte 32, et un bras 34 solidaire du premier axe 31 et s'étendant sensiblement radialement à partir de cet axe, vers l'extérieur, suivant une direction perpendiculaire au voile de liaison 33.It comprises a counterweight 32, for example of parallelepipedal shape, a connecting web 33 extending substantially radially from the first axis 31 and solidarisant this axis to a radially inner edge of the weight 32, and an arm 34 secured to the first axis 31 and extending substantially radially from this axis, outwards, in a direction perpendicular to the connecting web 33.

Le dispositif d'ouverture comprend en outre un organe élastique 35 sollicitant l'organe de sécurité 30 vers sa position de repos, et une butée 36 bloquant l'organe de sécurité 30 en rotation de sa position d'interdiction vers sa position de repos et définissant ainsi la position de repos.The opening device further comprises an elastic member 35 urging the safety member 30 towards its rest position, and a stop 36 blocking the safety member 30 in rotation from its prohibited position to its rest position and thus defining the rest position.

L'organe élastique 35 est un ressort en spirale engagé autour d'un ergot 51 formé sur un pan 52 de l'étrier 50 et pointant transversalement vers l'intérieur du véhicule, en direction de l'organe de sécurité 31. Il travaille en compression, et s'appui d'un côté sur le pan 52 et d'un côté opposé sur le voile de liaison 33. Ce voile de liaison 33 est percé d'un orifice 331 dans lequel vient s'engager l'extrémité libre de l'ergot 51 quand l'organe de sécurité pivote vers sa position d'interdiction à l'encontre de la force de rappel de l'organe élastique 35.The elastic member 35 is a spiral spring engaged around a lug 51 formed on a pan 52 of the stirrup 50 and pointing transversely towards the inside of the vehicle, in the direction of the safety member 31. It operates compression, and supported on one side on the pan 52 and an opposite side on the connecting web 33. This connecting web 33 is pierced with an orifice 331 in which is engaged the free end of the lug 51 when the safety member pivots towards its prohibited position against the restoring force of the elastic member 35.

En position de repos, illustrée sur la figure 4, la masselotte 32 et le voile de liaison 33 s'étendent longitudinalement vers l'arrière à partir du premier axe 31, le bras 34 s'étendant transversalement vers l'extérieur.In the rest position, illustrated in FIG. 4, the flyweight 32 and the connecting web 33 extend longitudinally rearwardly from the first axis 31, the arm 34 extending transversely outwards.

En cas de choc latéral sur l'ouvrant, la masselotte 32 pivote vers l'extérieur, de sensiblement 30°, le bras 34 pointant alors en oblique vers l'extérieur et vers l'avant, suivant une direction sensiblement perpendiculaire à celle du doigt d'actionnement 22 quand l'organe de renvoi 20 occupe sa position normale. Le bord 321 de la masselotte 32, radialement extérieur par rapport à l'axe 31, décrit une trajectoire en arc de cercle autour de l'axe 31. La masselotte 32 vient en butée contre le pan 52 de l'étrier 50, ce qui définit la position d'interdiction.In the event of a lateral impact on the opening leaf, the weight 32 pivots outwardly by approximately 30 °, the arm 34 then pointing obliquely outwardly and forwards in a direction substantially perpendicular to that of the finger actuator 22 when the return member 20 occupies its normal position. The edge 321 of the weight 32, radially outside relative to the axis 31, describes a trajectory in an arc around the axis 31. The weight 32 abuts against the pan 52 of the stirrup 50, which sets the prohibition position.

Quand l'organe de sécurité 30 occupe sa position d'interdiction, le bras 34 empêche l'organe de renvoi 20 de pivoter à partir de sa position normale vers sa position d'ouverture, le doigt d'actionnement 22 venant en butée contre le bras 34, comme illustré sur la figure 6.When the safety member 30 occupies its prohibited position, the arm 34 prevents the return member 20 to pivot from its normal position to its open position, the actuating finger 22 abuts against the arm 34, as shown in Figure 6.

Dans un premier mode de réalisation de l'invention, représenté sur les figures 4 à 7, les moyens de blocage 40 de l'organe de sécurité 30 comprennent une languette souple 41 solidaire de l'étrier 50, et au moins un relief 42 ménagé sur l'organe de sécurité 30 coopérant avec la languette souple 41 en position d'interdiction de l'organe de sécurité 30 pour bloquer la rotation de celui-ci vers sa position de repos .In a first embodiment of the invention, represented in FIGS. 4 to 7, the locking means 40 of the safety member 30 comprise a flexible tongue 41 integral with the stirrup 50, and at least one raised relief 42. on the safety member 30 cooperating with the flexible tongue 41 in the closed position of the safety member 30 to block the rotation thereof to its rest position.

La languette 41 s'étend à partir d'une nervure transversale 53 de l'étrier 50, disposée à l'arrière de l'organe de sécurité 30. Elle s'étend à partir de ladite nervure jusqu'à une extrémité libre 411, suivant une direction oblique vers l'extérieur et vers l'avant, ladite direction étant tangente à la trajectoire en arc de cercle du bord extérieur 321 de la masselotte 32, ou légèrement inclinée par rapport à ladite tangente.The tongue 41 extends from a transverse rib 53 of the stirrup 50, disposed at the rear of the safety member 30. It extends from said rib to a free end 411, in a direction oblique outwards and forwards, said direction being tangent to the arcuate path of the outer edge 321 of the weight 32, or slightly inclined relative to said tangent.

La languette 41 s'étend donc à partir de la nervure 53 vers l'extrémité libre 411 dans un sens correspondant au sens de rotation de la masselotte 32.The tongue 41 thus extends from the rib 53 towards the free end 411 in a direction corresponding to the direction of rotation of the weight 32.

Plus précisément, comme on le voit sur la figure 6, l'extrémité libre 411 de la languette 41 s'étend dans la zone de la trajectoire en arc de cercle occupée par le bord extérieur 321 en position d'interdiction de l'organe de sécurité 30.More precisely, as can be seen in FIG. 6, the free end 411 of the tongue 41 extends in the region of the arcuate trajectory occupied by the outer edge 321 in the interdicted position of the locking member. security 30.

Par ailleurs, le relief 42 est une concavité creusée dans le bord extérieur 321 de la masselotte, de telle sorte que, lors du déplacement de l'organe de sécurité 30 de sa position de repos à sa position d'interdiction, la masselotte 32 va venir porter par son bord extérieur 321 contre l'extrémité libre 411 de la languette 41 et soulever celle-ci vers l'extérieur, l'extrémité libre 411 tombant dans le relief 42 quand l'organe de sécurité 30 atteint sa position d'interdiction.Moreover, the relief 42 is a concavity dug in the outer edge 321 of the weight, so that, during the movement of the safety member 30 from its rest position to its prohibited position, the weight 32 goes come carry by its outer edge 321 against the free end 411 of the tongue 41 and lift it to the outside, the free end 411 falling in the relief 42 when the safety member 30 reaches its forbidden position.

Le relief 42 présente par exemple la forme d'une rainure verticale, à section en V, l'extrémité libre 411 venant se loger dans le fond du V.The relief 42 has for example the shape of a vertical groove, V-section, the free end 411 being housed in the bottom of V.

Le mouvement de l'organe de sécurité 30 à partir de sa position d'interdiction vers sa position de repos sous l'effet de l'effort de rappel de l'organe élastique 30 est bloqué par une des faces du V venant porter contre l'extrémité libre 411 et exerçant un effort sur celle-ci sensiblement parallèlement à la direction dans laquelle s'étend la languette 41.The movement of the safety member 30 from its prohibited position to its rest position under the effect of the return force of the elastic member 30 is blocked by one of the faces of the V against the free end 411 and exerting a force on it substantially parallel to the direction in which the tongue 41 extends.

Dans ce premier mode de réalisation, l'étrier 50 et la languette 41 sont réalisés en matière plastique, la languette 41 étant venue de moulage avec l'étrier 50. Les dimensions de la languette 41, en particulier son épaisseur, sont choisies pour que cette languette soit suffisamment souple pour être déplacée par la masselotte 32 dans son mouvement vers sa position d'interdiction, et suffisamment rigide pour résister sans se plier à l'effort exercé par l'organe élastique 35.In this first embodiment, the stirrup 50 and the tongue 41 are made of plastic, the tongue 41 being molded with the stirrup 50. The dimensions of the tongue 41, in particular its thickness, are chosen so that this tongue is sufficiently flexible to be displaced by the flyweight 32 in its movement towards its prohibited position, and sufficiently rigid to resist without bending to the force exerted by the elastic member 35.

Un second mode de réalisation de l'invention est représenté sur la figure 8 et 9, particulièrement adapté aux cas où l'étrier 50 est réalisé en métal ou en alliage métallique, la languette souple 41 étant particulièrement difficile à réaliser dans ce type de matériau.A second embodiment of the invention is shown in FIG. 8 and 9, particularly adapted to cases where the stirrup 50 is made of metal or metal alloy, the flexible tongue 41 being particularly difficult to produce in this type of material. .

Dans ce second mode de réalisation, les moyens de blocage 40 de l'organe de sécurité 30 comprennent une languette souple 41 solidaire de l'organe de renvoi 20, et un relief 42 ménagé sur l'organe de sécurité 30 coopérant avec la languette souple 41 en position d'interdiction de l'organe de sécurité 30 pour bloquer la rotation de celui-ci vers sa position de repos .In this second embodiment, the locking means 40 of the safety member 30 comprise a flexible tongue 41 integral with the return member 20, and a relief 42 formed on the safety member 30 cooperating with the flexible tongue 41 in the position of prohibition of the safety member 30 to block the rotation thereof to its rest position.

La languette souple 41 est formée sur le doigt d'actionnement 22 de l'organe de renvoi 20, et s'étend sensiblement perpendiculairement à celle-ci, suivant une direction inclinée vers l'arrière et l'intérieur, jusqu'à l'extrémité libre 411. La languette 41 est portée par une face 221 du doigt 22 tournée vers le bras 34, en un point de cette face radialement intermédiaire entre l'extrémité libre de ce doigt 22 et l'axe de rotation de l'organe de renvoi 20.The flexible tongue 41 is formed on the actuating finger 22 of the deflection member 20, and extends substantially perpendicularly thereto, in a direction inclined backwards and inwards, up to the free end 411. The tongue 41 is carried by a face 221 of the finger 22 facing the arm 34, at a point of this radially intermediate face between the free end of the finger 22 and the axis of rotation of the return member 20.

La languette 41 et le bras 34 de l'organe de sécurité 30 sont conformés de façon à s'imbriquer irréversiblement l'un avec l'autre quand l'organe de renvoi 20 est en butée par son doigt 22 contre le bras 34, de façon à bloquer la rotation de l'organe de sécurité 30 par rapport à l'organe de renvoi 20 vers sa position de repos.The tongue 41 and the arm 34 of the safety member 30 are shaped so as to interlock irreversibly with each other when the return member 20 is abutted by its finger 22 against the arm 34, way to block the rotation of the safety member 30 relative to the return member 20 to its rest position.

On voit sur la figure 8 que, quand l'organe de renvoi 20 est en butée sur le bras de blocage 34, la languette 41 est accolée le long de ce bras, le bras 34 et la languette 41 présentant des creux et des parties en saillie complémentaires qui s'interpénètrent et bloquent le bras 34 en rotation par rapport à l'organe de renvoi 20.It can be seen in FIG. 8 that, when the deflection member 20 is in abutment with the locking arm 34, the tongue 41 is contiguous along this arm, the arm 34 and the tongue 41 having recesses and portions thereof. complementary projection which interpenetrate and block the arm 34 in rotation relative to the return member 20.

A cet effet, la languette 41 porte à son extrémité libre une dent 412 faisant saillie vers le bras 34, la face latérale du bras 34 tournée vers la languette 41 étant conformée pour présenter du côté le plus éloigné de l'axe 31 une partie en saillie 341 et du côté le plus proche de l'axe 31 une partie en creux 342. La dent 412 vient se loger dans la partie en creux 342, contre la partie en saillie 341, de telle sorte que cette partie en saillie 341 est imbriquée entre la dent 412 et la face 221 du doigt 22. Du fait de cet imbriquement mutuel du bras et de la languette, la rotation du bras 34 est rendue impossible.For this purpose, the tongue 41 carries at its free end a tooth 412 projecting towards the arm 34, the lateral face of the arm 34 facing the tongue 41 being shaped so as to present on the side furthest from the axis 31 a portion of projection 341 and on the side closest to the axis 31 a recessed portion 342. The tooth 412 is housed in the recessed portion 342, against the projecting portion 341, so that this projecting portion 341 is nested between the tooth 412 and the face 221 of the finger 22. Due to this interlocking arm and tongue, the rotation of the arm 34 is made impossible.

Les parties en saillie et en creux 341 et 342 constituent le relief 42 des moyens de blocage 40.The protruding and recessed portions 341 and 342 constitute the relief 42 of the locking means 40.

La languette 41 est venue de moulage avec l'organe de renvoi, celui-ci étant de préférence constitué de matière plastique.The tab 41 is molded with the return member, the latter being preferably made of plastic.

Selon un autre aspect de l'invention, le dispositif d'ouverture comprend un écran amovible 60 interposé temporairement entre la languette souple 41 et le relief 42.According to another aspect of the invention, the opening device comprises a removable screen 60 temporarily interposed between the flexible tongue 41 and the relief 42.

En effet, le procédé de montage d'un dispositif d'ouverture du type décrit plus haut sur un ouvrant de véhicule automobile, comprend typiquement les étapes suivantes :

  • 1/ assemblage sur l'étrier 50, dans l'usine du fournisseur du dispositif d'ouverture, au moins de l'organe de renvoi 20 et de l'organe de sécurité 30, l'étrier ou l'organe de renvoi portant la languette 41, et l'organe de sécurité portant le relief 42,
  • 3/ transport du sous-ensemble constitué de l'étrier 50, de l'organe de renvoi 20 et de l'organe de sécurité 30 jusqu'à la chaîne de fabrication du véhicule automobile,
  • 4/ mise en place du sous-ensemble sur l'ouvrant 1, montage de la poignée 10 sur l'étrier 50.
Indeed, the method of mounting an opening device of the type described above on an opening of a motor vehicle, typically comprises the following steps:
  • 1 / assembly on the caliper 50, in the factory of the supplier of the opening device, at least of the return member 20 and the safety member 30, the stirrup or the return member carrying the tongue 41, and the safety member carrying the relief 42,
  • 3 / transport of the subassembly consisting of the stirrup 50, the return member 20 and the safety member 30 to the production line of the motor vehicle,
  • 4 / placing the subassembly on the opening 1, mounting the handle 10 on the bracket 50.

Il peut arriver que, au cours de l'étape 3/, l'organe de sécurité 30 soit déplacé en position d'interdiction, par exemple si le conteneur de transport du sous-ensemble subit un choc en cours de manutention. Les moyens de blocage 40 bloquent alors irréversiblement l'organe de sécurité 30 en position de sécurité, rendant le sous-ensemble inutilisable.It may happen that, during step 3 /, the safety member 30 is moved to the prohibited position, for example if the transport container of the subassembly is shocked during handling. The locking means 40 then irreversibly block the safety member 30 in the safety position, making the subassembly unusable.

Pour supprimer ce risque, on interpose pendant le transport du sous-ensemble un écran amovible 60 entre la languette souple 41 et le relief 42.To eliminate this risk, during transport of the subassembly a removable screen 60 is interposed between the flexible tongue 41 and the relief 42.

L'écran amovible 60 est constitué d'une bande de matière souple, par exemple une bande de papier de forme allongée.The removable screen 60 is made of a strip of flexible material, for example an elongated paper strip.

Dans le premier mode de réalisation du dispositif d'ouverture, une première extrémité 61 de la bande 60 est plaquée longitudinalement contre un côté extérieur de l'étrier 50, la bande 60 étant ensuite pliée pour passer transversalement entre la nervure 53 et l'organe de sécurité 30, en plaquant la languette 41 contre cette nervure 53.In the first embodiment of the opening device, a first end 61 of the strip 60 is pressed longitudinally against an outer side of the yoke 50, the strip 60 then being folded to pass transversely between the rib 53 and the member of safety 30, by pressing the tongue 41 against this rib 53.

La bande 60 est ensuite encore pliée, et s'étend longitudinalement contre une face intérieure de l'étrier 50. Elle se termine par une seconde extrémité 62 libre, dépassant largement de l'étrier 50, et susceptible d'être saisie manuellement. La première extrémité 61 est fixée sur l'étrier 50, par exemple par collage, de façon à pouvoir être détachée de l'étrier quand on exerce une traction sur la seconde extrémité. La bande 60 présente une résistance intrinsèque au déchirement supérieure à l'effort nécessaire pour détacher la première extrémité 61 de l'étrier 50.The band 60 is then further folded, and extends longitudinally against an inner face of the stirrup 50. It ends with a second free end 62, extending far beyond the stirrup 50, and capable of being manually grasped. The first end 61 is fixed on the stirrup 50, for example by gluing, so that it can be detached from the stirrup when traction is exerted on the second end. The band 60 has an intrinsic tear strength greater than the force required to detach the first end 61 of the stirrup 50.

Cet écran 60 est mis en place dans l'usine du fournisseur, au cours d'une étape 2/ suivant l'étape 1/et précédant l'étape 3/.This screen 60 is set up in the supplier's factory, during a step 2 / following step 1 / and preceding step 3 /.

A l'étape 4/, le sous-ensemble est monté sur l'ouvrant, de façon à ce que le côté extérieur de l'étrier soit plaqué contre la peau extérieure 101 de l'ouvrant 1, de telle sorte la première extrémité 61 de la bande 60 est pincée entre la peau 101 et l'étrier 50, la seconde extrémité 62 restant saisissable manuellement.In step 4 /, the subassembly is mounted on the opening, so that the outer side of the stirrup is pressed against the outer skin 101 of the opening 1, so that the first end 61 the band 60 is pinched between the skin 101 and the stirrup 50, the second end 62 remaining manually grippable.

Au cours d'une étape 5/ suivant l'étape 4/, la bande 60 est retirée par traction sur sa seconde extrémité 62 saisissable manuellement.During a step 5 / following step 4 /, the band 60 is withdrawn by traction on its second end 62 manually grippable.

Dans le second mode de réalisation du dispositif d'ouverture, la première extrémité 61 de la bande 60 est fixée du côté extérieur de l'étrier 50, la bande passant ensuite entre le bras 34 et le doigt d'actionnement 22, puis le long du côté intérieur de l'étrier 50.In the second embodiment of the opening device, the first end 61 of the band 60 is fixed on the outside of the stirrup 50, the band then passing between the arm 34 and the actuating finger 22, then along on the inside of the stirrup 50.

On comprend donc bien que le dispositif d'ouverture décrit ci-dessus présente de multiples avantages.It is therefore clear that the opening device described above has multiple advantages.

L'organe de sécurité est bloqué par la languette 41 en position d'interdiction, de telle sorte que le dispositif d'ouverture est insensible au phénomène de rebonds décalés des différents éléments qui le constituent. Le risque d'ouverture accidentel de l'ouvrant en cas de choc est supprimé.The safety member is blocked by the tongue 41 in the prohibited position, so that the opening device is insensitive to the phenomenon of offset rebounds of the various elements that the up. The risk of accidental opening of the sash in the event of impact is eliminated.

En outre, du fait que l'organe de sécurité reste bloquée en position d'interdiction, la barrière de choc utilisée pour les essais d'impact ne peut plus provoquer le déverrouillage de l'ouvrant en se retirant après l'impact.In addition, because the safety member remains locked in the prohibited position, the impact barrier used for the impact tests can no longer cause the unlocking of the opening by withdrawing after the impact.

Ce résultat est atteint par des moyens mécaniquement très simples, peu coûteux et d'encombrement extrêmement réduit.This result is achieved by mechanically very simple means, inexpensive and extremely small footprint.

Les éléments constituant le dispositif d'ouverture ne sont pratiquement pas modifiés par rapport à l'art antérieur, ni dans leur forme, ni dans leur agencement. Le dispositif de l'invention peu donc être implanté dans pratiquement tous les ouvrants.The elements constituting the opening device are practically not modified with respect to the prior art, neither in their form nor in their arrangement. The device of the invention can therefore be implanted in virtually all the openings.

Le dispositif a été décrit pour des ouvrants latéraux d'un véhicule automobile. Il est parfaitement adapté aux ouvrants latéraux avant et arrière, ou même à un ouvrant de type hayon arrière.The device has been described for lateral opening of a motor vehicle. It is perfectly adapted to the front and rear side windows, or even to a tailgate type opening.

L'écran amovible permet de transporter le système de sécurité pré-monté sur l'étrier, sans risque de blocage intempestif de celui-ci par les moyens de blocage.The removable screen can transport the security system pre-mounted on the caliper, without the risk of inadvertent blocking thereof by the locking means.

L'écran peut être constitué d'une autre matière que du papier, par exemple une matière plastique.The screen may consist of another material than paper, for example a plastic material.

Le dispositif peut comprendre un étrier en matière plastique ou un étrier métallique, en fonction des caractéristiques de l'ouvrant à équiper.The device may comprise a plastic stirrup or a metal stirrup, depending on the characteristics of the opening to be equipped.
