Abstract

The vehicle door handle (2) is arranged in such a way that an inertial mass (18) in the handle passes irreversibly from a rest configuration in which it allows the door to be opened into a locking configuration in which it prevents opening and passes from the locking configuration into an unlocked configuration, different from the rest configuration and from the locking configuration, the handle being arranged so that placement of the inertial mass (18) in the unlocking configuration has the effect of it once again being possible for the door to be opened.

Description

Poignée d'ouvrant de véhicule comprenant une masse inertielle L' invention concerne les poignées d'ouvrant de véhicule.  The invention relates to vehicle opening handles comprising an inertial mass.
On connaît des poignées d'ouvrant équipées d'un système inertiel apte, en cas de choc latéral et sous l'effet de la variation d'accélération, à prendre une position de blocage qui inhibe le mécanisme de la poignée pour interdire toute ouverture intempestive de l'ouvrant.  Sash handles are known that are equipped with an inertial system which, in the event of a side impact and under the effect of the variation of acceleration, can take a blocking position which inhibits the mechanism of the handle to prevent any inadvertent opening. of the opening.
On connaît en particulier des systèmes inertiels de type réversible et des systèmes inertiels de type irréversible.  Inertial systems of the reversible type and inertial systems of the irreversible type are known in particular.
Un système réversible revient en position de repos à l'issue du choc. Il a pour avantage de permettre l'ouverture de l'ouvrant au moyen de la poignée après le choc. A reversible system returns to the rest position at the end of the shock. It has the advantage of allowing the opening of the opening by means of the handle after the shock.
Il a toutefois pour inconvénient d'être en général très sensible aux accélérations latérales dans les deux sens, ainsi qu'aux rebonds. Ainsi, s'il se produit des variations de direction de l'accélération lors du choc, il se peut que le système revienne à sa position de repos et rende à nouveau actif le mécanisme de la poignée qui se trouvait initialement inhibé. Cela peut entraîner le déplacement de la poignée sous l'effet du choc et l'ouverture de l'ouvrant. However, it has the disadvantage of being generally very sensitive to lateral accelerations in both directions, as well as rebounds. Thus, if there are variations in the direction of the acceleration during the impact, the system may return to its rest position and activate again the mechanism of the handle that was initially inhibited. This can cause the handle to move under the impact and open the opening.
Un système inertiel irréversible demeure en position de blocage pendant toute la durée du choc et après ce dernier. Il a pour avantage de ne pas être sensible aux variations d'accélération durant le choc, ni aux rebonds. On est donc sûr que le mécanisme de poignée est convenablement inhibé pendant toute la durée du choc, de sorte que l'ouvrant ne s'ouvre pas. Ce système a toutefois pour inconvénient que le mécanisme de poignée demeure inhibé après le choc et rend donc impossible l'ouverture volontaire de l'ouvrant par la manœuvre de la poignée.  An irreversible inertial system remains in the locked position for the duration of the shock and after the shock. It has the advantage of not being sensitive to variations in acceleration during the shock, or rebounds. It is therefore certain that the handle mechanism is properly inhibited throughout the duration of the shock, so that the opening does not open. This system however has the disadvantage that the handle mechanism remains inhibited after the shock and thus makes it impossible to open the opening manually by the operation of the handle.
Un but de l'invention est de disposer d'une poignée qui combine les avantages des deux types de système sans leurs inconvénients.  An object of the invention is to have a handle that combines the advantages of both types of system without their disadvantages.
A cet effet, on prévoit, selon l'invention, une poignée d'ouvrant de véhicule, agencée de sorte qu'une masse inertielle de la poignée passe de façon irréversible d'une configuration de repos dans laquelle elle autorise une ouverture de l'ouvrant à une configuration de blocage dans laquelle elle interdit l'ouverture et passe de la configuration de blocage à une configuration de déblocage puis à la configuration de repos.  For this purpose, according to the invention, there is provided a handle of a vehicle opening, arranged so that an inertial mass of the handle irreversibly passes from a rest configuration in which it allows an opening of the opening to a blocking configuration in which it prohibits the opening and passes from the blocking configuration to an unlock configuration and then to the idle configuration.
Ainsi, grâce au passage irréversible de la configuration de repos à la configuration de blocage, le mécanisme de poignée demeure inhibé pendant toute la durée du choc. On évite donc toute ouverture intempestive de l'ouvrant durant le choc. Néanmoins, à l'issue du passage de la configuration de blocage à la configuration de déblocage puis à la configuration de repos, le mécanisme de poignée est rendu à nouveau actif, si bien que l'ouvrant peut être ouvert pour  Thus, thanks to the irreversible transition from the rest configuration to the locking configuration, the handle mechanism remains inhibited throughout the duration of the shock. It avoids any inadvertent opening of the opening during the shock. Nevertheless, at the end of the transition from the blocking configuration to the unblocking configuration and then to the rest configuration, the handle mechanism is made active again, so that the opening can be opened for
FEU I LLE DE REM PLACEM ENT (RÈG LE 26) permettre la sortie d'un occupant du véhicule. Cette poignée combine donc les avantages des systèmes des deux types précités, tout en palliant leurs inconvénients. FIRE I LLE OF REM PLACEM ENT (RULE 26) allow the exit of an occupant of the vehicle. This handle thus combines the advantages of the systems of the two aforementioned types, while overcoming their disadvantages.
De préférence, la poignée comprend des moyens d'encliquetage aptes à immobiliser la masse en configuration de blocage lorsqu'elle y parvient à partir de la configuration de repos.  Preferably, the handle comprises latching means adapted to immobilize the blocking configuration mass when it arrives therefrom from the rest configuration.
Avantageusement, la poignée est agencée de sorte que le passage de la configuration de blocage à la configuration de déblocage entraîne un débrayage des moyens d'encliquetage.  Advantageously, the handle is arranged so that the passage of the locking configuration to the unlocking configuration causes a disengagement of the latching means.
De préférence, la poignée est agencée de sorte que le passage de la configuration de blocage à la configuration de déblocage est commandable au moyen d'un organe externe de la poignée.  Preferably, the handle is arranged so that the passage from the locking configuration to the unlocking configuration is controllable by means of an external member of the handle.
Ainsi, moyennant une commande volontaire sur l'organe externe, le mécanisme de poignée se trouve désinhibé. Cette commande peut être effectuée par un occupant du véhicule ou une personne extérieure selon les cas et le mode de réalisation choisi pour la poignée. Elle a lieu notamment lorsque l'ouverture peut se faire sans danger.  Thus, with a voluntary command on the external member, the handle mechanism is uninhibited. This command can be performed by a vehicle occupant or an outside person depending on the case and the embodiment chosen for the handle. It takes place especially when the opening can be done without danger.
Avantageusement, l'organe externe est un organe de commande de l'ouverture de l'ouvrant.  Advantageously, the external member is a control member of the opening of the opening.
Ainsi, c'est l'organe de commande de la poignée lui-même qui permet de désinhiber le mécanisme pour l'ouverture de l'ouvrant.  Thus, it is the control member of the handle itself that disinhibits the mechanism for opening the opening.
De préférence, la poignée est agencée de sorte que le passage de la configuration de blocage à la configuration de déblocage est commandable seulement au moyen d'une sollicitation qui présente une intensité dépassant un seuil prédéterminé.  Preferably, the handle is arranged so that the transition from the blocking configuration to the unlocking configuration is controllable only by means of a bias that has an intensity exceeding a predetermined threshold.
Ainsi, on réduit les risques de déblocage intempestif du mécanisme de la poignée. La personne qui souhaite ouvrir l'ouvrant doit en effet fournir un effort particulier en ce sens.  Thus, it reduces the risk of inadvertent release of the mechanism of the handle. The person who wishes to open the door must indeed make a special effort in this direction.
Dans un mode de réalisation, la poignée comprend une butée agencée pour être déformée lors du passage de la configuration de blocage à la configuration de déblocage.  In one embodiment, the handle comprises an abutment arranged to be deformed during the transition from the locking configuration to the unlocking configuration.
Il s'agit d'une façon particulièrement simple de mettre en œuvre la caractéristique précitée relative au seuil d'intensité.  This is a particularly simple way of implementing the aforementioned characteristic relating to the intensity threshold.
Avantageusement, la poignée comprend un organe de rappel de la masse vers la configuration de repos.  Advantageously, the handle comprises a body for restoring the mass to the rest configuration.
De préférence, l'un parmi un support et la masse présente une rampe et l'autre parmi le support et la masse comporte un suiveur apte à venir en appui sur la rampe,  Preferably, one of a support and the mass has a ramp and the other of the support and the mass comprises a follower adapted to bear on the ramp,
FEU I LLE DE REMPLACEM ENT (RÈG LE 26) de sorte que la rampe et le suiveur guident le passage de la configuration de repos à la configuration de blocage puis à la configuration de déblocage. FIRE REPLACEM ENT (RULE 26) so that the ramp and the follower guide the transition from the idle configuration to the blocking configuration and then to the unlocking configuration.
Dans un mode de réalisation, la masse est montée rotative sur un support de la poignée.  In one embodiment, the mass is rotatably mounted on a support of the handle.
D'autres caractéristiques et avantages de l'invention apparaîtront encore dans la description suivante d'un mode de réalisation donnée à titre d'exemple non limitatif, en référence aux dessins annexés sur lesquels :  Other features and advantages of the invention will become apparent in the following description of an embodiment given by way of non-limiting example, with reference to the accompanying drawings in which:
- les figures 1 à 3 sont trois vues en coupe horizontale d'une poignée selon un mode de réalisation de l'invention, montrant respectivement trois étapes du fonctionnement de la poignée ;  - Figures 1 to 3 are three views in horizontal section of a handle according to one embodiment of the invention, respectively showing three steps of operation of the handle;

- la figure 10 est une vue en élévation montrant le trajet du suiveur par rapport à la rampe dans la poignée des figures précédentes.  - Figure 10 is an elevational view showing the path of the follower relative to the ramp in the handle of the previous figures.
Nous allons décrire ci-après un mode de réalisation d'une poignée d'ouvrant de véhicule automobile selon l'invention. L'ouvrant peut être une portière avant, une portière arrière ou encore un haillon. Il s'agit en l'espèce d'une poignée externe permettant la manœuvre de l'ouvrant pour son déverrouillage et son ouverture depuis l'extérieur du véhicule. L'invention est néanmoins également applicable à une poignée interne pour l'ouverture de l'ouvrant.  We will describe below an embodiment of a motor vehicle opening handle according to the invention. The opening can be a front door, a rear door or a rag. This is an external handle for the maneuver of the opening for unlocking and opening from outside the vehicle. The invention is nevertheless also applicable to an internal handle for opening the opening.
On utilise dans la suite le repère orthogonal XYZ dans lequel les directions horizontales X et Y sont respectivement parallèle et perpendiculaire à la direction de marche du véhicule et la direction Z est verticale.  The orthogonal coordinate system XYZ is used in the following, in which the horizontal directions X and Y are respectively parallel and perpendicular to the direction of travel of the vehicle and the direction Z is vertical.
En référence tout d'abord aux figures 1 à 3, la poignée 2 comprend un support ou bâti 4 rigidement fixé à la structure de l'ouvrant.  Referring firstly to Figures 1 to 3, the handle 2 comprises a support or frame 4 rigidly fixed to the structure of the opening.
Elle comprend une partie de préhension externe 6 destinée à être actionnée à la main par un utilisateur souhaitant ouvrir l'ouvrant depuis l'extérieur du véhicule. Cette partie 6 est, en l'espèce, articulée au support 4 autour d'un axe vertical 8 et ce, par des moyens connus en eux-mêmes qui ne sont pas détaillés ici. La partie de préhension 6 se prolonge à l'intérieur de la poignée et de l'ouvrant par une extension It comprises an external gripping portion 6 intended to be actuated manually by a user wishing to open the opening from outside the vehicle. This part 6 is, in this case, hinged to the support 4 around a vertical axis 8 and this by means known in themselves which are not detailed here. The gripping portion 6 extends inside the handle and opens it with an extension
10 s'étendant suivant la direction Y. 10 extending in the Y direction.
La poignée 2 comprend un levier 12 monté mobile à rotation par rapport au support 4 autour d'un axe vertical 14. Ce levier comprend notamment un bras 16 s'étendant dans le trajet d'un rebord d'extrémité de l'extension 10 de sorte que, lorsqu'un utilisateur manœuvre la partie de préhension 6 vers l'extérieur suivant la direction Y, l'extension 10 emporte le bras 16, ce qui fait tourner le levier 12. Deux positions du levier 12 autour de son axe ont été illustrées à la figure 1.  The handle 2 comprises a lever 12 mounted to rotate relative to the support 4 about a vertical axis 14. This lever comprises in particular an arm 16 extending in the path of an end edge of the extension 10 of so that when a user maneuvers the gripping portion 6 outward in the Y direction, the extension 10 carries the arm 16, which rotates the lever 12. Two positions of the lever 12 about its axis have been illustrated in Figure 1.
FEU I LLE DE REM PLACEM ENT (RÈGLE 26) Le levier est relié d'une façon non illustrée, et qui ne sera pas décrite ici, à d'autres pièces du mécanisme de poignée, notamment à un câble de traction. Ce mécanisme sert à déverrouiller l'ouvrant par rapport à la caisse du véhicule. FIREPLACE OF REM PLACEM ENT (RULE 26) The lever is connected in a manner not shown, and which will not be described here, to other parts of the handle mechanism, in particular to a traction cable. This mechanism serves to unlock the opening relative to the vehicle body.
La poignée 2 comprend aussi un système inertiel comportant une pièce 18 formant une masse montée mobile à rotation par rapport au support 4 autour d'un axe vertical 20. Cette pièce comprend deux parties profilées 22 et 24 donnant à la pièce telle que vue en coupe sur les figures 1 à 3 une forme générale en « V ».  The handle 2 also comprises an inertial system comprising a part 18 forming a mass mounted to rotate relative to the support 4 about a vertical axis 20. This part comprises two profiled parts 22 and 24 giving the part as seen in section in Figures 1 to 3 a general shape in "V".
La masse 18 peut occuper différentes positions autour de son axe 20.  The mass 18 can occupy different positions around its axis 20.
Dans la position de repos illustrée à la figure 1, la partie de blocage 22 s'étend hors de la trajectoire du levier 12, de sorte qu'elle autorise sa rotation, et permet de commander l'ouverture de l'ouvrant par l'action de la partie de préhension 6.  In the rest position illustrated in Figure 1, the locking portion 22 extends beyond the path of the lever 12, so that it allows its rotation, and allows to control the opening of the opening by the action of the grip part 6.
Dans la position de blocage illustrée à la figure 2, la partie de compression 24 de la masse 18 est en appui contre une butée 26 rigidement solidaire du support 4. La partie de blocage 22 s'étend dans la trajectoire du levier 12 qu'elle empêche ainsi de tourner, de sorte qu'elle inhibe le mécanisme de poignée. Elle retient en effet de ce fait la partie de préhension 6 en position et empêche l'ouverture de l'ouvrant.  In the blocking position illustrated in FIG. 2, the compression portion 24 of the mass 18 is in abutment against a stop 26 rigidly secured to the support 4. The locking portion 22 extends in the trajectory of the lever 12 that it thus prevents rotation, so that it inhibits the handle mechanism. It actually holds the gripping portion 6 in position and prevents the opening of the opening.
La partie de compression 24 a une masse plus grande que celle de la partie de blocage 22.  The compression portion 24 has a mass greater than that of the locking portion 22.
Un ressort de rappel 19 de la masse vers sa position de repos prend appui d'une part sur la masse et d'autre part sur le support 4.  A return spring 19 of the mass towards its rest position is supported on the one hand on the mass and on the other hand on the support 4.
On peut déjà, à l'appui des figures 1 à 3, avoir un aperçu du fonctionnement de la poignée qui sera néanmoins présenté plus bas plus en détail.  We can already, in support of Figures 1 to 3, have an overview of the operation of the handle which will nevertheless be presented below in more detail.
La figure 1 illustre la poignée dans la configuration de repos de toutes les pièces. La partie de blocage 22 s'étend hors de la trajectoire du levier et sa partie de compression 24 s'étend à distance de la butée 26. Si un utilisateur souhaite ouvrir l'ouvrant, il actionne la partie de préhension qui entraîne avec l'extension 10 le levier 12 en rotation autour de son axe pour provoquer le déverrouillage de l'ouvrant. Le ressort de rappel 19 maintient la masse 18 hors de la trajectoire du levier 12 afin que l'extension 10 puisse librement entraîner ce dernier.  Figure 1 shows the handle in the rest configuration of all parts. The locking portion 22 extends out of the path of the lever and the compression portion 24 extends away from the stop 26. If a user wishes to open the opening, it actuates the gripping portion which leads with the extension 10 the lever 12 in rotation about its axis to cause the unlocking of the opening. The return spring 19 keeps the mass 18 out of the path of the lever 12 so that the extension 10 can freely drive the latter.
En référence à la figure 2, on suppose que se produit un choc latéral du véhicule suivant la direction Y et que ce choc est tel que la partie de préhension 6 amorce un déplacement par inertie vers l'extérieur du véhicule. La masse inertielle 18 s'est déplacée préalablement en tournant dans le sens anti-horaire par rapport à sa position de la figure 1 jusqu'à mettre la partie 24 en appui contre la butée 26. Dans cette configuration de blocage, la partie 22 s'étend dans la trajectoire du levier 12 dont elle empêche toute rotation supplémentaire, malgré la sollicitation exercée par l'extension 10. La partie de préhension se trouve donc retenue en position à  With reference to FIG. 2, it is assumed that there is a lateral collision of the vehicle in the Y direction and that this shock is such that the gripping portion 6 initiates inertial displacement towards the outside of the vehicle. The inertial mass 18 has been moved beforehand by turning counter-clockwise with respect to its position in FIG. 1 until the part 24 bears against the abutment 26. In this locking configuration, the part 22 is extends in the trajectory of the lever 12 which it prevents any further rotation, despite the bias exerted by the extension 10. The gripping portion is therefore held in position at
FEU I LLE DE REM PLACEM ENT (RÈG LE 26) l'encontre de la force générée par l'accélération du choc. On évite ainsi toute ouverture intempestive de l'ouvrant. Comme on le verra dans la suite, le passage de la masse 18 de la configuration de repos de la figure 1 à la configuration de blocage de la figure 2 s'effectue de façon irréversible, de sorte que cette masse demeure dans la configuration de blocage pendant tout le choc et après la fin de ce dernier. FIRE I LLE OF REM PLACEM ENT (RULE 26) against the force generated by the acceleration of the shock. This avoids any inadvertent opening of the opening. As will be seen in the following, the passage of the mass 18 of the rest configuration of FIG. 1 to the blocking configuration of FIG. 2 is irreversibly effected so that this mass remains in the blocking configuration during the whole shock and after the end of it.
On suppose à la figure 3 que la phase de choc est achevée et qu'un utilisateur souhaite ouvrir l'ouvrant depuis l'extérieur. L'utilisateur actionne la partie de préhension 6 en fournissant une force ayant une intensité dépassant un seuil prédéterminé et tel que la sollicitation transmise par le levier 12 à la masse 18 force cette dernière à déformer la butée 26. Ce mouvement fait passer la masse 18 de la configuration de blocage de la figure 2 à la configuration de déblocage illustrée à la figure 3.  It is assumed in Figure 3 that the shock phase is completed and a user wishes to open the opening from the outside. The user actuates the gripping portion 6 by providing a force having an intensity exceeding a predetermined threshold and such that the bias transmitted by the lever 12 to the mass 18 forces the latter to deform the stop 26. This movement causes the mass 18 to pass. from the blocking configuration of FIG. 2 to the unlocking configuration illustrated in FIG.
L'utilisateur relâche la partie de préhension, ce qui provoque le retour de la masse 18 dans la configuration de repos sous l'effet du ressort.  The user releases the gripping portion, which causes the return of the mass 18 in the rest configuration under the effect of the spring.
En manoeuvrant à nouveau la partie de préhension 6, l'utilisateur peut donc ouvrir normalement l'ouvrant.  Maneuvering the gripping portion 6 again, the user can therefore open the opening normally.
Nous allons décrire maintenant plus en détail certains aspects de la poignée 2. We will now describe in more detail some aspects of the handle 2.
La partie de compression 24 de la masse 18 porte à son extrémité libre une languette 28 s'étendant parallèlement à l'axe 20. La languette est rigidement fixée à la partie 24 par sa zone d'extrémité inférieure et uniquement par cette dernière de sorte qu'elle est élastiquement flexible par rapport au reste de la masse 18. C'est au niveau de sa zone d'extrémité supérieure libre qu'elle présente la plus grande amplitude de déplacement par rapport au reste de cette pièce. The compression portion 24 of the mass 18 carries at its free end a tongue 28 extending parallel to the axis 20. The tongue is rigidly fixed to the portion 24 by its lower end zone and only by the latter. it is elastically flexible relative to the rest of the mass 18. It is at its upper free end zone that it has the greatest range of displacement relative to the rest of this room.
Le support 4 présente sur une paroi supérieure 32 un relief 34 formant une rampe pour la languette 28 qui tient le rôle de suiveur. Le relief 34 présente une face avant courbe convexe 36, une face interne 38, une face avant 40, une face interne 42 et une face arrière 44. Les faces 38, 40, 42 et 44 sont planes et verticales. Les faces 38 et 42 sont perpendiculaires à la direction Y tandis que les faces 40 et 44 sont perpendiculaires à la direction X.  The support 4 has on an upper wall 32 a relief 34 forming a ramp for the tongue 28 which takes the role of follower. The relief 34 has a convex curved front face 36, an inner face 38, a front face 40, an inner face 42 and a rear face 44. The faces 38, 40, 42 and 44 are flat and vertical. The faces 38 and 42 are perpendicular to the Y direction while the faces 40 and 44 are perpendicular to the X direction.
Le relief et la languette forment des moyens d'encliquetage agencés pour coopérer comme suit.  The relief and the tongue form latching means arranged to cooperate as follows.
On a illustré à la figure 10 différente positions de l'extrémité libre de la languette 28 par rapport au relief 34.  FIG. 10 shows different positions of the free end of the tongue 28 relative to the relief 34.
Dans la position de repos a illustrée aux figures 1 et 5, l'extrémité de la languette 28 s'étend en regard du relief et de la partie arrière de la face courbe 36.  In the rest position illustrated in FIGS. 1 and 5, the end of the tongue 28 extends facing the relief and the rear part of the curved face 36.
Lorsque la masse 18 passe de la configuration de repos à la configuration de blocage, la languette 28 vient en contact avec la partie arrière de la face 36, puis, par  When the mass 18 passes from the idle configuration to the lock configuration, the tongue 28 comes into contact with the rear part of the face 36, then, by
FEU I LLE DE REM PLACEM ENT (RÈG LE 26) effet de rampe, suit cette dernière jusqu'à la position b à son extrémité intérieure. Ce contact est maintenu le long de la face 36 en raison de la sollicitation élastique de la languette sur le relief, compte tenu de la déformation de la languette. Après que la languette a franchi l'extrémité intérieure de la face 36, elle est ramenée élastiquement en arrière contre la face 40 et demeure en butée à la fois contre cette dernière et contre la face 38 à la position c. On a alors atteint la configuration de blocage. Compte tenu de cette butée, la masse 18 n'est pas en mesure de passer directement de la configuration de blocage à la configuration de repos par le mouvement inverse, rendant ainsi irréversible le mouvement qui vient d'être présenté. FIRE I LLE OF REM PLACEM ENT (RULE 26) ramp effect, follows the latter to the position b at its inner end. This contact is maintained along the face 36 due to the elastic biasing of the tongue on the relief, given the deformation of the tongue. After the tongue has passed the inner end of the face 36, it is brought back elastically against the face 40 and abuts both against the latter and against the face 38 at the position c. We then reached the blocking configuration. Given this stop, the mass 18 is not able to pass directly from the blocking configuration to the rest configuration by the reverse movement, thus making the movement that has just been presented irreversible.
Lorsque, à partir de la configuration de blocage, un utilisateur actionne la partie de préhension 6 pour forcer la rotation de la masse à rencontre de la butée 26, la languette 28 passe suivant la direction Y de la position c à la position d dans laquelle elle ne se trouve plus en butée contre la facette 40 suivant la direction X. Elle est en regard de la face 38 mais plus de la face 40. La force de rappel élastique résultant de la déformation de la languette emmène donc cette dernière suivant la direction X à la position e, au delà de la face 44, après avoir franchi la face 42. Une butée rigide additionnelle peut être prévue pour empêcher de manière certaine un déplacement de la masse au delà de la position de déblocage lorsque celle-ci est ainsi déplacée depuis la position de blocage.  When, from the blocking configuration, a user actuates the gripping portion 6 to force the rotation of the mass against the stop 26, the tongue 28 passes in the Y direction of the position c to the position d in which it is no longer in abutment against the facet 40 in the direction X. It is opposite the face 38 but more than the face 40. The elastic restoring force resulting from the deformation of the tongue thus takes the latter in the direction X at the position e, beyond the face 44, after passing the face 42. An additional rigid stop may be provided to prevent a certain movement of the mass beyond the unlocking position when it is so moved from the lock position.
Lorsque l'utilisateur relâche la partie de préhension 6, la rotation du levier 12 dans le sens anti-horaire permet la rotation de la masse 18 dans le sens horaire sous l'effet du ressort 19. Cette rotation est permise puisque le relief 34 ne s'étend plus dans la trajectoire de la languette. Celle-ci se déplace donc suivant la direction Y en regard de la face 44 pour revenir à la position a.  When the user releases the gripping portion 6, the rotation of the lever 12 in the counterclockwise direction allows the rotation of the mass 18 in the clockwise direction under the effect of the spring 19. This rotation is allowed since the relief 34 extends further in the path of the tongue. This then moves in the direction Y opposite the face 44 to return to the position a.
Au cours de ce fonctionnement, la trajectoire de l'extrémité de la languette forme une boucle et ne repasse pas deux fois par la même position. Il s'ensuit en particulier que la masse 18 doit passer à partir de la configuration de blocage par la configuration de déblocage pour pouvoir revenir à la configuration de repos.  During this operation, the trajectory of the end of the tongue forms a loop and does not go back twice in the same position. It follows in particular that the mass 18 must pass from the blocking configuration by the unblocking configuration to be able to return to the idle configuration.
La butée 26 est élastique. Ses dimensions et sa forme conditionnent l'intensité de l'effort que l'utilisateur doit fournir pour faire passer la masse 18 de la configuration de blocage à la configuration de déblocage.  The stop 26 is elastic. Its dimensions and its shape condition the intensity of the effort that the user must provide to pass the mass 18 of the blocking configuration to the unlocking configuration.
On observe que la languette 28 et le relief 34 forment des moyens d'encliquetage. La position embrayée ou encliquetée correspond à la configuration de blocage. Le passage de cette dernière à la configuration de déblocage entraîne un débrayage des moyens d'encliquetage.  It is observed that the tongue 28 and the relief 34 form latching means. The engaged or snapped position corresponds to the blocking configuration. The passage of the latter to the unlocking configuration causes a disengagement of the latching means.
FEU I LLE DE REM PLACEM ENT (RÈG LE 26) La poignée selon l'invention a donc tout à la fois pour avantage de procurer un système inertiel irréversible qui reste donc en configuration de blocage pendant tout le choc et à l'issue de ce dernier, et de permettre l'ouverture volontaire de l'ouvrant sur commande d'un utilisateur après le choc. FIRE I LLE OF REM PLACEM ENT (RULE 26) The handle according to the invention thus has both the advantage of providing an irreversible inertial system which remains in blocking configuration during the whole shock and at the end of the latter, and to allow the voluntary opening of the opening on command of a user after the shock.
Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci.  Of course, we can bring to the invention many changes without departing from the scope thereof.
On pourrait prévoir que le passage de la configuration de blocage à la configuration de déblocage est commandable au moyen d'un organe autre que la partie de préhension externe ou qu'une partie de préhension interne de la poignée, par exemple au moyen d'un organe spécifiquement destiné à cette fin.  It could be provided that the transition from the blocking configuration to the unlocking configuration is controllable by means of a member other than the external gripping portion or an internal gripping portion of the handle, for example by means of a organ specifically designed for this purpose.
La butée déformable pourrait être portée par la masse inertielle et non par le support.  The deformable stop could be carried by the inertial mass and not by the support.
Dans un mode de réalisation, on peut prévoir que l'axe de rotation de la masse inertielle est choisi suffisamment déformable pour que l'on adopte une butée 26 rigide, la déformabilité autorisant le passage à la configuration de déblocage étant assurée par la déformabilité de l'axe pour une basculement élastique de la masse 18 autour de la butée 26.  In one embodiment, it can be provided that the axis of rotation of the inertial mass is chosen sufficiently deformable so that a rigid stop 26 is adopted, the deformability allowing the transition to the unlocking configuration being ensured by the deformability of the axis for an elastic tilting of the mass 18 around the abutment 26.
On pourrait prévoir que la languette 28 soit portée par le support et que le relief soit porté par la masse inertielle.  One could predict that the tongue 28 is carried by the support and that the relief is carried by the inertial mass.
Dans un mode de réalisation de l'invention, la configuration de déblocage est en elle-même une configuration où l'ouverture de l'ouvrant par actionnement de l'organe de préhension extérieur est autorisée.  In one embodiment of the invention, the unlocking configuration is in itself a configuration where the opening of the opening by actuation of the external gripper is allowed.
C'est le cas notamment lorsque l'on prévoit que la masse inertielle 18 est déplaçable en force hors du trajet du levier 12 pour laisser ce levier atteindre sa position de commande d'ouverture de l'ouvrant. Le retour en position de repos peut ensuite être autorisé ou non. L'autorisation du retour en position de repos est par exemple réalisée par le moyens décrits en référence à la figure 10.  This is particularly the case when it is expected that the inertial mass 18 is displaceable in force out of the path of the lever 12 to allow the lever to reach its open opening control position. The return to the rest position can then be allowed or not. The authorization of the return to the rest position is for example carried out by the means described with reference to FIG.
L'effacement de la masse inertielle 18 est également réalisable en prévoyant que la masse inertielle vient en appui sous l'effet du choc contre une ou des butées élastiques mais ne vient en appui contre aucune butée rigide contrairement au mode de réalisation décrit ci-dessus où une telle butée rigide additionnelle peut être prévue pour stopper de manière certaine la masse en position de déblocage.  The erasure of the inertial mass 18 is also feasible by providing that the inertial mass abuts under the effect of the impact against one or more elastic stops but does not bear against any rigid abutment contrary to the embodiment described above. where such additional rigid abutment can be provided to surely stop the mass in unlocking position.
La butée en matière plastique déformable 26 est alors prévue avec une rigidité propre à empêcher un effacement de la masse inertielle sous l'effet de l'inertie du choc telle que transmise sur la masse inertielle par le levier 12, mais suffisamment souple pour autoriser un l'effacement de la masse inertielle en écrasement de la  The plastic deformable abutment 26 is then provided with a rigidity to prevent erasure of the inertial mass under the effect of the inertia of the shock as transmitted to the inertial mass by the lever 12, but flexible enough to allow a the erasure of the inertial mass in crushing of the
FEU I LLE DE REM PLACEM ENT (RÈG LE 26) butée 26 sous l'effet d'une traction manuelle sur l'organe de préhension extérieur de la poignée. FIRE I LLE OF REM PLACEM ENT (RULE 26) stop 26 under the effect of a manual pull on the external gripping member of the handle.
Selon un autre mode de réalisation la butée déformable 18 peut être remplacée par un ressort à lame ou hélicoïdal, dont la rigidité et la course sont réglés dans ce même but.  According to another embodiment the deformable stop 18 may be replaced by a leaf or helical spring, whose rigidity and stroke are adjusted for the same purpose.
La butée déformable 26 peut également être réalisée sous la forme d'un patin en élastomère fixé sur le support de poignée et dont la déformabilité autorise la masse inertielle à ne plus inhiber l'ouverture lorsque la poignée est forcée en ouverture, mais suffisamment ferme pour arrêter la masse inertielle dans la configuration de blocage sous l'effet des forces d'inertie transmises sur celle-ci notamment via le levier de transmission. Le positionnement d'une telle butée élastomère est par exemple le même que celui de la butée élastique 26 précédemment décrite.  The deformable stop 26 may also be made in the form of an elastomer pad fixed on the handle support and whose deformability allows the inertial mass to no longer inhibit the opening when the handle is forced open, but sufficiently firm to stopping the inertial mass in the locking configuration under the effect of the inertial forces transmitted on it notably via the transmission lever. The positioning of such an elastomeric stop is for example the same as that of the elastic abutment 26 previously described.
Selon encore un mode de réalisation, on prévoit un butée pour la masse 18, rigide ou élastique, et un axe de rotation de la masse inertielle 18 présentant une déformabilité qui est propre à autoriser un basculement de la masse inertielle hors du trajet du levier 12, par déplacement de la masse inertielle transversalement à cet axe. L'axe est alors avantageusement réalisé en métal et à retour élastique pour une remise en situation de fonctionnement initial de la poignée après un choc puis un forçage en ouverture de la poignée. L'axe de rotation est par exemple choisi suffisamment déformable pour que l'on adopte une butée 26 de type rigide pour la masse inertielle, la déformabilité autorisant le passage à la configuration de déblocage étant assurée par la déformabilité de l'axe lui-même. Là encore, avantageusement l'axe présente une rigidité suffisante pour le maintien de la masse inertielle dans la configuration de blocage sous l'effet des seules forces d'inertie.  According to another embodiment, there is provided a stop for the mass 18, rigid or elastic, and an axis of rotation of the inertial mass 18 having a deformability which is adapted to allow a tilting of the inertial mass out of the path of the lever 12 , by displacement of the inertial mass transversely to this axis. The axis is then advantageously made of metal and elastic return for a return to the original operating situation of the handle after a shock and forcing opening the handle. The axis of rotation is for example chosen sufficiently deformable so that one adopts a stop 26 of rigid type for the inertial mass, the deformability allowing the passage to the unlocking configuration being ensured by the deformability of the axis itself . Again, advantageously the axis has a sufficient rigidity for maintaining the inertial mass in the locking configuration under the effect of only inertial forces.
