Description

L'invention concerne le domaine technique des ouvrants arrières pour véhicule automobile.The invention relates to the technical field of rear doors for a motor vehicle.

Elle s'applique en particulier, mais non exclusivement, aux véhicules automobiles de tourisme, notamment ceux présentant un ouvrant arrière formant un hayon.It applies in particular, but not exclusively, to passenger automobiles, especially those having a rear opening forming a tailgate.

On connaît déjà de l'état de la technique un ouvrant arrière pour véhicule automobile monté mobile en rotation par rapport à la caisse autour d'un axe transversal géométrique du véhicule, dit axe de l'ouvrant, entre :

  • une position "ouvrant fermé" dans laquelle l'ouvrant obture une ouverture de caisse du véhicule automobile, et
  • une position "ouvrant ouvert" dans laquelle l'ouvrant libère au moins en partie l'ouverture.
Already known from the state of the art a rear door for a motor vehicle rotatably mounted relative to the body about a transverse geometric axis of the vehicle, said axis of the opening, between:
  • a position "opening closed" in which the opening seals a cash opening of the motor vehicle, and
  • an "open opening" position in which the opening releases at least part of the opening.

Cet axe transversal est matérialisé par des charnières situées dans une partie haute de l'ouvrant.This transverse axis is materialized by hinges located in an upper part of the opening.

On comprendra par caisse une structure métallique, couramment désignée « caisse en blanc », formant une armature rigide du véhicule, destinée à supporter différents organes, notamment les ouvrants, le groupe motopropulseur, les essieux, les pièces de carrosserie, l'habillage intérieur, etc.It will be understood by body a metal structure, commonly referred to as "white box", forming a rigid armature of the vehicle, intended to support different bodies, including the opening, powertrain, axles, body parts, interior trim, etc.

L'ouvrant comprend des moyens de soutien aptes à générer un couple autour de l'axe de l'ouvrant afin de compenser, au moins en partie, le couple généré par le poids de l'ouvrant autour de l'axe de l'ouvrant.The opening comprises support means capable of generating a torque around the axis of the opening to compensate, at least in part, the torque generated by the weight of the opening around the axis of the opening .

Les moyens de soutien comprennent deux équilibreurs pneumatiques qui exercent une poussée sensiblement constante sur l'ouvrant. Les moyens de soutien sont reliés à la caisse par des premiers moyens de liaison et à l'ouvrant par des deuxièmes moyens de liaison. Chaque premier et deuxième moyens de liaison comprend par exemple des rotules.The support means comprise two pneumatic balancers which exert a substantially constant thrust on the opening. The support means are connected to the body by first connecting means and the opening by second connecting means. Each first and second connecting means comprises, for example, ball joints.

Toutefois, les équilibreurs de ce type d'ouvrant sont encombrants et inesthétiques notamment dans la position d'ouverture de l'ouvrant.However, balancers of this type of opening are bulky and unsightly especially in the open position of the opening.

L'invention a pour but de fournir une alternative à ces équilibreurs.The invention aims to provide an alternative to these balancers.

A cet effet, l'invention a pour objet un ouvrant arrière pour véhicule automobile destiné à être monté mobile en rotation par rapport à la caisse autour d'un axe transversal géométrique du véhicule, dit axe de l'ouvrant, entre :

  • une position "ouvrant fermé" dans laquelle l'ouvrant obture une ouverture de caisse du véhicule automobile, et
  • une position "ouvrant ouvert" dans laquelle l'ouvrant libère au moins en partie l'ouverture,
l'ouvrant comprenant des moyens de soutien de l'ouvrant aptes à générer un couple de sollicitation autour de l'axe de l'ouvrant, caractérisé en ce que les moyens de soutien comprennent :
  • au moins un axe de déplacement fixe par rapport à l'ouvrant ou à la caisse,
  • au moins un élément apte à se déplacer le long de l'axe de déplacement,
  • des moyens de traction aptes à exercer une force de traction sur chaque élément pour le déplacer le long de l'axe de déplacement,
  • au moins un organe fixé d'une part à la caisse ou à l'ouvrant et d'autre part à l'élément, apte à exercer une force de poussée sur la caisse ou sur l'ouvrant à laquelle ou auquel l'organe est fixé, sous l'effet de la force de traction.
For this purpose, the subject of the invention is a rear opening for a motor vehicle intended to be mounted mobile in rotation with respect to the body around a transverse axis of the vehicle, said axis of the opening, between:
  • a position "opening closed" in which the opening seals a cash opening of the motor vehicle, and
  • an "open opening" position in which the opening releases at least part of the opening,
the opening comprising means for supporting the opening adapted to generate a biasing torque around the axis of the opening, characterized in that the support means comprise:
  • at least one axis of fixed displacement relative to the opening or to the body,
  • at least one element able to move along the axis of displacement,
  • traction means able to exert a traction force on each element to move it along the axis of displacement,
  • at least one member fixed on the one hand to the body or the opening and on the other hand to the element, able to exert a thrust force on the body or on the opening to which or to which the body is fixed, under the effect of the pulling force.

Les moyens de soutien de l'ouvrant selon l'invention sont relativement compacts et esthétiques. En effet, contrairement à l'ouvrant de l'état de la technique dans lequel les équilibreurs se déplacent par rapport à l'ouvrant et à la caisse, l'axe de déplacement des moyens de soutien de l'ouvrant selon l'invention est fixe par rapport à la caisse ou l'ouvrant et ne génère donc pas d'encombrement inutile.The support means of the opening according to the invention are relatively compact and aesthetic. Indeed, unlike the opening of the state of the art in which the balancers move relative to the opening and to the body, the axis of movement of the support means of the opening according to the invention is fixed relative to the box or the opening and therefore does not generate unnecessary space.

De plus, le ou les axes, le ou les éléments et les moyens de traction peuvent être intégrés dans la caisse ou l'ouvrant selon que l'axe est fixe par rapport à la caisse ou à l'ouvrant, ce qui rend les moyens de soutien relativement discrets et esthétiques.In addition, the axis or axes, the element or elements and the traction means can be integrated in the box or the opening according to whether the axis is fixed relative to the body or the opening, which makes the means relatively discreet and aesthetic support.

Dans le cas où l'axe est fixe par rapport à la caisse, l'organe exerce une force de poussée sur l'ouvrant auquel il est fixé, ce qui permet de soutenir l'ouvrant.In the case where the axis is fixed relative to the body, the member exerts a thrust force on the opening to which it is attached, which allows to support the opening.

Dans le cas où l'axe est fixe par rapport à l'ouvrant, l'organe exerce une force de poussée sur la caisse à laquelle il est fixé. Par réaction, la caisse exerce une force de réaction sur l'ouvrant qui permet également de soutenir l'ouvrant.In the case where the axis is fixed relative to the opening, the member exerts a thrust force on the body to which it is attached. By reaction, the body exerts a reaction force on the opening which also supports the opening.

Dans un mode de réalisation de l'ouvrant selon l'invention, les moyens de traction comprennent au moins un élément élastiquement déformable.In one embodiment of the opening according to the invention, the traction means comprise at least one elastically deformable element.

En variante, les moyens de traction comprennent des équilibreurs pneumatiques ou hydrauliques.In a variant, the traction means comprise pneumatic or hydraulic balancers.

Selon une caractéristique optionnelle de l'ouvrant selon l'invention, chaque élément élastiquement déformable comprend au moins un ressort destiné à être comprimé ou étiré sur l'axe de déplacement et fixé à l'élément.According to an optional feature of the opening according to the invention, each elastically deformable element comprises at least one spring intended to be compressed or stretched on the axis of displacement and fixed to the element.

Contrairement à un équilibreur pneumatique, ces moyens de soutien ne sont pas sensibles à la température. De plus, dans le cas d'un équilibreur pneumatique, la pression peut chuter et diminuer le couple généré par l'équilibreur. L'utilisateur doit alors fournir un couple supplémentaire pour ouvrir l'ouvrant et veiller à ce que l'ouvrant ne retombe pas depuis sa position d'ouverture sans être retenu par l'équilibreur. L'ouvrant selon ce mode de réalisation de l'invention permet d'éviter ce problème.Unlike a pneumatic balancer, these support means are not sensitive to temperature. In addition, in the case of a pneumatic balancer, the pressure can drop and decrease the torque generated by the balancer. The user must then provide additional torque to open the opening and ensure that the opening does not fall from its open position without being retained by the balancer. The opening according to this embodiment of the invention avoids this problem.

En outre, l'élément élastiquement déformable exerce une poussée non constante. La variation et la valeur du couple de sollicitation en fonction de la position de l'ouvrant peuvent donc être paramétrées notamment en fonction des caractéristiques mécaniques de l'élément élastiquement déformable. L'élément élastiquement déformable permet donc de paramétrer la variation du couple de sollicitation de l'ouvrant et donc de réduire facilement le couple que l'utilisateur doit apporter pour ouvrir et fermer l'ouvrant.In addition, the elastically deformable element exerts a non-constant thrust. The variation and the value of the biasing torque as a function of the position of the opening can therefore be parameterized in particular according to the mechanical characteristics of the elastically deformable element. The elastically deformable element thus makes it possible to parameterize the variation of the biasing torque of the sash and thus to easily reduce the torque that the user must bring to open and close the sash.

Selon une autre caractéristique optionnelle de l'ouvrant selon l'invention, le ressort est déformable entre :

  • une première position d'allongement dans laquelle le ressort présente une première longueur d'allongement, la première position d'allongement correspondant à la position "ouvrant fermé" de l'ouvrant; et
  • une deuxième position d'allongement dans laquelle le ressort présente une deuxième longueur d'allongement inférieure à la première, la deuxième position d'allongement correspondant à la position "ouvrant ouvert" de l'ouvrant.
According to another optional feature of the opening according to the invention, the spring is deformable between:
  • a first extension position in which the spring has a first length of elongation, the first extension position corresponding to the "opening closed" position of the opening; and
  • a second extension position in which the spring has a second length of elongation less than the first, the second extension position corresponding to the "open open" position of the opening.

Dans un mode de réalisation de l'ouvrant selon l'invention, les moyens de traction comprennent des moyens motorisés.In one embodiment of the opening according to the invention, the traction means comprise motorized means.

Des moyens motorisés relativement compacts et peu chers peuvent être utilisés. En effet, le couple que l'utilisateur doit apporter pour fermer et ouvrir l'ouvrant pouvant être relativement réduit, les moyens motorisés peuvent être peu puissants, ce qui réduit leur taille et leur coût.Motorized means relatively compact and inexpensive can be used. Indeed, the torque that the user must bring to close and open the opening can be relatively reduced, the motorized means may be low power, which reduces their size and cost.

Dans un mode de réalisation de l'ouvrant selon l'invention, l'axe de déplacement est porté par l'ouvrant.In one embodiment of the opening according to the invention, the axis of displacement is carried by the opening.

Dans un autre mode de réalisation de l'ouvrant selon l'invention, l'axe de déplacement est destiné à être porté par la caisse.In another embodiment of the opening according to the invention, the axis of movement is intended to be carried by the body.

Selon une caractéristique optionnelle de l'ouvrant selon l'invention, les moyens de soutien étant respectivement reliés à la caisse et à l'ouvrant respectivement par des premier et deuxième moyens de liaison, les premier et deuxième moyens de liaison présentent respectivement des premier et deuxième axes géométriques de rotation sensiblement parallèles à l'axe de l'ouvrant autour desquels les moyens de soutien sont aptes à pivoter respectivement par rapport à la caisse et l'ouvrant, et dans la position de fermeture de l'ouvrant:

  • l'axe de l'ouvrant et le deuxième axe géométrique de rotation des moyens de soutien autour de l'ouvrant forment deux génératrices diamétralement opposées d'un cylindre géométrique à l'intérieur duquel ou sur lequel se situe le premier axe géométrique de rotation des moyens de soutien autour de la caisse, et
  • dans un plan vertical longitudinal du véhicule, la cote verticale du deuxième axe géométrique de rotation des moyens de soutien autour de l'ouvrant est supérieure ou égale à la cote verticale du premier axe géométrique de rotation des moyens de soutien autour de la caisse.
According to an optional feature of the opening according to the invention, the support means being respectively connected to the body and the opening respectively by first and second connecting means, the first and second connecting means respectively have first and second second geometric axes of rotation substantially parallel to the axis of the opening around which the support means are pivotable respectively relative to the body and the opening, and in the closed position of the opening:
  • the axis of the opening and the second geometric axis of rotation of the support means around the opening form two diametrically opposed generatrices of a geometric cylinder inside or on which is located the first geometric axis of rotation of the means of support around the box, and
  • in a longitudinal vertical plane of the vehicle, the vertical dimension of the second geometric axis of rotation of the support means around the opening is greater than or equal to the vertical dimension of the first geometric axis of rotation of the support means around the body.

Dans un premier type d'ouvrant de l'état de la technique, dans le plan vertical longitudinal du véhicule et dans la position "ouvrant fermé" de l'ouvrant, la cote verticale du deuxième axe géométrique de rotation des moyens de soutien autour de l'ouvrant est supérieure à la cote verticale du premier axe géométrique de rotation des moyens de soutien autour de la caisse. Toutefois, les équilibreurs de ce type d'ouvrant sont encombrants et inesthétiques notamment dans la position d'ouverture de l'ouvrant.In a first type of opening of the state of the art, in the longitudinal vertical plane of the vehicle and in the "opening closed" position of the opening, the vertical dimension of the second geometric axis of rotation of the support means around the opening is greater than the vertical dimension of the first geometric axis of rotation of the support means around the body. However, balancers of this type of opening are bulky and unsightly especially in the open position of the opening.

Dans un deuxième type d'ouvrant de l'état de la technique, dans le plan vertical longitudinal du véhicule et dans la position "ouvrant fermé" de l'ouvrant, la cote verticale du deuxième axe géométrique de rotation des moyens de soutien autour de l'ouvrant est inférieure à la cote verticale du premier axe géométrique de rotation des moyens de soutien autour de la caisse. Dans ce deuxième type d'ouvrant, le couple généré par les équilibreurs décroît de façon monotone entre les positions "ouvrant ouvert" et "ouvrant fermé" si bien qu'il est nécessaire de disposer d'équilibreurs présentant une poussée très importante pour compenser le couple généré par le poids de l'ouvrant. Ainsi, le couple à fournir par un utilisateur pour fermer ce type d'ouvrant est relativement grand ce qui le rend difficile à manipuler pour certaines personnes.In a second type of opening of the state of the art, in the longitudinal vertical plane of the vehicle and in the "opening closed" position of the opening, the vertical dimension of the second geometric axis of rotation of the support means around the opening is less than the vertical dimension of the first geometric axis of rotation of the support means around the body. In this second type of opening, the torque generated by the balancers decreases monotonically between the "open open" and "open closed" positions so that it is necessary to have balancers with a very large thrust to compensate the torque generated by the weight of the opening. Thus, the couple to provide a user to close this type of opening is relatively large which makes it difficult to handle for some people.

Les moyens de soutien tels que défini ci-dessus de l'ouvrant selon l'invention sont relativement compacts, ce qui favorise notamment l'esthétique du véhicule et permet un accès facile au coffre du véhicule. En effet, le premier axe géométrique se situant dans ou sur le cylindre géométrique, les moyens de soutien sont regroupés dans un volume relativement réduit. En outre, la cote verticale du deuxième axe géométrique étant supérieure ou égale à la cote verticale du premier axe dans le plan vertical longitudinal, la cote verticale du deuxième axe est relativement proche de celle de l'axe principal de rotation de façon à ne pas exclure le premier axe géométrique du cylindre géométrique. Ainsi, les moyens de soutien sont compacts.The support means as defined above of the opening according to the invention are relatively compact, which particularly promotes the aesthetics of the vehicle and allows easy access to the trunk of the vehicle. Indeed, the first geometric axis being in or on the geometric cylinder, the support means are grouped in a relatively small volume. In addition, since the vertical dimension of the second geometric axis is greater than or equal to the vertical dimension of the first axis in the longitudinal vertical plane, the vertical dimension of the second axis is relatively close to that of the main axis of rotation so as not to exclude the first geometric axis of the geometric cylinder. Thus, the support means are compact.

L'ouvrant est également facile à manipuler. En effet, le couple généré par le poids croit sur une plage de positions successives entre la position "ouvrant fermé" et une position intermédiaire, puis décroît depuis cette position intermédiaire jusque dans la position "ouvrant ouvert". Le couple de sollicitation est fonction de la distance, dite distance à l'axe, entre l'axe de rotation de l'ouvrant et une droite géométrique passant, dans le plan vertical longitudinal, par les premier et deuxième axes géométriques. Le premier axe géométrique se situant dans le cylindre géométrique, la distance à l'axe croit depuis sur une plage de positions successives depuis la position de "ouvrant fermé" de l'ouvrant jusque dans une position intermédiaire de l'ouvrant, puis décroît depuis la position intermédiaire jusque dans la position "ouvrant ouvert" de l'ouvrant. Le couple de sollicitation présente alors une variation sensiblement similaire à celle du couple généré par le poids, ce qui permet à un utilisateur de fermer et ouvrir l'ouvrant en fournissant un couple relativement faible, correspondant à la différence entre le couple généré par le poids et le couple de sollicitation.The opening is also easy to handle. Indeed, the torque generated by the weight increases over a range of successive positions between the "open closed" position and an intermediate position, then decreases from this intermediate position into the "open open" position. The biasing torque is a function of the distance, said distance to the axis, between the axis of rotation of the opening and a geometrical line passing, in the longitudinal vertical plane, the first and second geometric axes. The first geometric axis lying in the geometric cylinder, the distance to the axis is from a range of successive positions from the "opening closed" position of the opening to an intermediate position of the opening, then decreases from the intermediate position to the "open open" position of the opening. The biasing torque then has a variation substantially similar to that of the torque generated by the weight, which allows a user to close and open the opening by providing a relatively low torque, corresponding to the difference between the torque generated by the weight. and the solicitation torque.

De plus, grâce à de tels moyens de soutien, la variation de la distance à l'axe est relativement facile à contrôler. En conséquence, il est facile de contrôler la variation du couple généré par les moyens de soutien. Il est donc aisé de réaliser un ouvrant dont la variation et la valeur du couple de sollicitation sont proches de celles du couple généré par le poids de l'ouvrant. Ainsi, le couple que l'utilisateur doit apporter pour fermer et ouvrir l'ouvrant peut être choisi et réduit autant que faire se peut pour que l'ouvrant soit le plus facile possible à manipuler. Idéalement, le couple généré par les moyens de soutien est constamment sensiblement égal au couple généré par le poids (compte tenu des éventuels frottements mécaniques) de sorte que l'ouvrant est constamment en équilibre entre les positions d'ouverture et de fermeture.In addition, thanks to such support means, the variation of the distance to the axis is relatively easy to control. As a result, it is easy to control the variation of the torque generated by the support means. It is therefore easy to make an opening whose variation and the value of the biasing torque are close to those of the torque generated by the weight of the opening. Thus, the torque that the user must bring to close and open the door can be chosen and reduced as much as possible so that the door is the easiest possible to handle. Ideally, the torque generated by the support means is constantly substantially equal to the torque generated by the weight (taking into account any mechanical friction) so that the opening is constantly in equilibrium between the open and closed positions.

En outre, le couple généré par les moyens de soutien pouvant être relativement petit, les forces exercées sur la caisse et l'ouvrant sont également relativement petites ce qui permet d'éviter de renforcer la caisse et l'ouvrant dans des zones d'effort sur lesquelles les moyens de soutien exercent leurs forces.In addition, the torque generated by the support means can be relatively small, the forces exerted on the body and the opening are also relatively small which avoids strengthening the box and opening in areas of effort on which the means of support exert their forces.

Dans un mode de réalisation non revendiqué, les moyens de soutien comprennent au moins un équilibreur pneumatique ou hydraulique.In an unclaimed embodiment, the support means comprise at least one pneumatic or hydraulic balancer.

L'invention a également pour objet un véhicule automobile caractérisé en ce qu'il comprend un ouvrant tel que défini ci-dessus.The invention also relates to a motor vehicle characterized in that it comprises an opening as defined above.

Sur les figures, on a représenté des axes X, Y, Z orthogonaux entre eux correspondant aux orientations habituelles longitudinale X, transversale Y et verticale Z d'un véhicule automobile, l'axe X étant orienté de l'avant vers l'arrière du véhicule.In the figures, there are shown X, Y, Z orthogonal axes between them corresponding to the usual longitudinal orientations X, transverse Y and vertical Z of a motor vehicle, the X axis being oriented from front to rear of the vehicle.

On a représenté sur les figures 1 à 4 un véhicule 10 selon l'invention comprenant un ouvrant selon un premier mode de réalisation désigné par la référence 12.We have shown on Figures 1 to 4 a vehicle 10 according to the invention comprising an opening according to a first embodiment designated by the reference 12.

Le véhicule 10 comprend une caisse 14 présentant une ouverture de caisse 16 permettant un accès à l'intérieur du véhicule 10 notamment à un coffre de stockage 18.The vehicle 10 comprises a box 14 having a cash register opening 16 allowing access to the interior of the vehicle 10, in particular to a storage box 18.

La caisse 14 comprend deux montants dits verticaux 20, 22 et deux montants dits transversaux supérieur 24 et inférieur 26 reliant les deux montant verticaux 20 et 22 entre eux. Le montant transversal supérieur 24 prolonge le toit 28 du véhicule 10 vers l'arrière de celui-ci. Chaque montant vertical 20, 22 et transversal 24, 26 délimite un partie de l'ouverture 16.The body 14 comprises two so-called vertical uprights 20, 22 and two so-called upper transverse uprights 24 and lower 26 connecting the two vertical uprights 20 and 22 between them. The upper transverse amount 24 extends the roof 28 of the vehicle 10 towards the rear thereof. Each vertical upright 20, 22 and transverse 24, 26 delimits a part of the opening 16.

L'ouvrant 12 est monté mobile en rotation par rapport à la caisse 14 autour d'un axe transversal T du véhicule sensiblement parallèle à la direction Y, dit axe de l'ouvrant, entre :

  • une position "ouvrant fermé", aussi appelée position de fermeture, représentée sur les figures 1 et 2, dans laquelle l'ouvrant 12 obture l'ouverture de caisse 16, et
  • une position "ouvrant ouvert" aussi appelée position d'ouverture, représentée sur les figures 3 et 4, dans laquelle l'ouvrant 12 libère au moins en partie l'ouverture 16.
The opening 12 is rotatably mounted relative to the body 14 about a transverse axis T of the vehicle substantially parallel to the Y direction, said axis of the opening, between:
  • a "closed opening" position, also called a closed position, represented on the Figures 1 and 2 , in which the opening 12 closes the body opening 16, and
  • an "open opening" position also called the open position, represented on the Figures 3 and 4 , in which the opening 12 releases at least part of the opening 16.

L'axe T est matérialisé par des charnières 30 fixées à la caisse 14 et à l'ouvrant 12.The T axis is materialized by hinges 30 fixed to the body 14 and the opening 12.

L'ouvrant 12 comprend également des moyens de soutien 32 de l'ouvrant 12 aptes à générer un couple de sollicitation autour de l'axe T. Les moyens de soutien 32 sont reliés à la caisse 14 par des premiers moyens de liaison 34. Les moyens de soutien 32 sont reliés à l'ouvrant 12 par des deuxièmes moyens de liaison 36.The opening 12 also comprises means 32 for supporting the opening 12 capable of generating a biasing torque around the axis T. The support means 32 are connected to the body 14 by first connecting means 34. support means 32 are connected to the opening 12 by second connecting means 36.

Comme représenté sur les figures 3 et 5 à 7, les moyens de soutien 32 comprennent un axe 40 de déplacement et deux éléments 41, 42 aptes à se déplacer, en l'espèce à coulisser, le long de l'axe 40 de déplacement. Chaque élément 41, 42 est également apte à pivoter autour de l'axe 40.As shown on figures 3 and 5 to 7 , the support means 32 comprise a displacement axis 40 and two elements 41, 42 able to move, in this case to slide, along the axis 40 of displacement. Each element 41, 42 is also pivotable about the axis 40.

Les moyens de soutien 32 comprennent également des moyens de traction 43 des éléments 41, 42. Ces moyens 43 sont aptes à exercer une force de traction sur chaque élément 41, 42 pour le déplacer le long de l'axe de déplacement 40.The support means 32 also comprise traction means 43 of the elements 41, 42. These means 43 are able to exert a traction force on each element 41, 42 to move it along the axis of displacement 40.

En outre, les moyens de soutien 32 comprennent deux organes 48, 50 aptes à exercer une force de poussée sur l'ouvrant 12 sous l'effet de la force de traction. Chaque organe 48, 50 est d'une part fixé à l'ouvrant 12 par les deuxième moyens de liaison 36 et, d'autre part, fixé à l'élément 41, 42 correspondant par une liaison pivot 52, 54. Chaque organe 48, 50 comprend une tige rigide 56, 58.In addition, the support means 32 comprise two members 48, 50 able to exert a thrust force on the opening 12 under the effect of the traction force. Each member 48, 50 is on the one hand fixed to the opening 12 by the second connecting means 36 and, on the other hand, fixed to the element 41, 42 corresponding by a pivot connection 52, 54. Each member 48 , 50 comprises a rigid rod 56, 58.

Les moyens de traction 43 comprennent un élément élastiquement déformable 38. Comme représenté sur les figures 3 et 5 à 7, l'élément 38 comprend un ressort 39 déformable entre :

  • une première position d'allongement, représentée sur la figure 7, dans laquelle le ressort 39 présente une première longueur L1 d'allongement et
  • une deuxième position d'allongement, représentée sur la figure 5, dans laquelle le ressort 39 présente une deuxième longueur L2 d'allongement inférieure à la première.
The traction means 43 comprise an elastically deformable element 38. As shown in FIGS. figures 3 and 5 to 7 the element 38 comprises a deformable spring 39 between:
  • a first position of extension, represented on the figure 7 , in which the spring 39 has a first length L1 of elongation and
  • a second position of extension, represented on the figure 5 in which the spring 39 has a second length L2 of elongation less than the first.

La première position d'allongement correspond à la position de fermeture de l'ouvrant 12 alors que la deuxième position d'allongement correspond à la position d'ouverture de l'ouvrant 12. Entre ces deux positions, le ressort peut prendre plusieurs positions d'allongement intermédiaires dans lesquelles il présente, pour chacune de ces positions, une longueur L3 intermédiaire comprise entre la première longueur L1 et la deuxième longueur L2.The first extension position corresponds to the closing position of the opening 12 while the second extension position corresponds to the open position of the opening 12. Between these two positions, the spring can take several positions of intermediate lengthening in which it presents, for each of these positions, an intermediate length L3 between the first length L1 and the second length L2.

Comme représenté sur ces mêmes figures 3 et 5 à 7, le ressort 39 est comprimé ou étiré sur l'axe 40 respectivement lorsqu'un utilisateur ouvre ou ferme l'ouvrant 12. L'axe 40 est sensiblement parallèle à la direction Y et donc à l'axe d'ouvrant T. L'axe de déplacement 40 comprend deux butées 44, 46 de limitation du déplacement transversal respectivement de chaque élément 41, 42 sur l'axe 40.As represented on these same figures 3 and 5 to 7 the spring 39 is compressed or stretched on the axis 40 respectively when a user opens or closes the opening 12. The axis 40 is substantially parallel to the direction Y and thus to the axis of opening T. L ' displacement axis 40 comprises two stops 44, 46 for limiting the transverse displacement respectively of each element 41, 42 on the axis 40.

L'axe 40 est porté par la caisse 14, en l'espèce, fixé au montant transversal supérieur 24, par les premiers moyens de liaison, par exemple par des vis ou par soudure. L'axe 40 est donc fixe par rapport à la caisse 14.The axis 40 is carried by the body 14, in this case, attached to the upper transverse amount 24, by the first connecting means, for example by screws or welding. The axis 40 is therefore fixed relative to the body 14.

Les deuxièmes moyens de liaison 36 comprennent deux liaisons rotules 60, 62.The second connecting means 36 comprise two ball joints 60, 62.

En référence aux figures 2 et 8, les premiers moyens de liaison 34 présentent un premier axe géométrique A1 de rotation sensiblement parallèle à l'axe de l'ouvrant T autour duquel les moyens de soutien 32 sont aptes à pivoter par rapport à la caisse 14. Ce premier axe A1 est matérialisé par l'axe 40. Les deuxièmes moyens de liaison 36 présentent un deuxième axe géométrique A2 de rotation sensiblement parallèle à l'axe de l'ouvrant T et à l'axe A1 autour duquel les moyens de soutien 32 sont aptes à pivoter par rapport à l'ouvrant 12. Ce deuxième axe A2 est matérialisé par les rotules 60, 62 aptes, par ailleurs, à pivoter autour des axes X et Z. L'axe géométrique A1 est fixe par rapport à la caisse alors que l'axe géométrique A2 est mobile par rapport à la caisse.With reference to figures 2 and 8 , the first connecting means 34 have a first geometric axis A1 of rotation substantially parallel to the axis of the opening T around which the support means 32 are pivotable relative to the body 14. This first axis A1 is materialized by the axis 40. The second connecting means 36 have a second geometric axis A2 of rotation substantially parallel to the axis of the opening T and the axis A1 around which the support means 32 are pivotable relative to to the opening 12. This second axis A2 is embodied by the ball joints 60, 62 able, moreover, to pivot about the axes X and Z. The geometric axis A1 is fixed relative to the body while the geometric axis A2 is mobile with respect to the body.

Comme illustré sur la figure 8, dans la position de fermeture de l'ouvrant 12, l'axe de l'ouvrant T et le deuxième axe géométrique A2 forment deux génératrices diamétralement opposées d'un cylindre géométrique R à l'intérieur duquel ou sur lequel se situe le premier axe géométrique A1. Dans cette même position de fermeture de l'ouvrant 12 et dans un plan vertical longitudinal P du véhicule 10 parallèle au plan XZ illustré à la figure 1, la cote verticale Z2 du deuxième axe géométrique A2 est supérieure ou égale à la cote verticale Z1 du premier axe géométrique A1. Par cote verticale, on entend l'altitude par rapport au sol selon l'axe Z de chaque axe projeté dans le plan P.As illustrated on the figure 8 , in the closed position of the opening 12, the axis of the opening T and the second geometric axis A2 form two diametrically opposite generatrices of a geometric cylinder R inside or on which is located the first axis geometric A1. In this same closing position of the opening 12 and in a longitudinal vertical plane P of the vehicle 10 parallel to the XZ plane illustrated in FIG. figure 1 the vertical dimension Z2 of the second geometric axis A2 is greater than or equal to the vertical dimension Z1 of the first geometric axis A1. By vertical dimension, we mean the altitude relative to the ground along the Z axis of each axis projected in the plane P.

En outre, dans la position de fermeture et dans le plan P, la cote verticale ZT de l'axe T est supérieure à la cote verticale Z2 de l'axe A2. Les axes T, A1 et A2 sont disposés le long de l'axe X dans cet ordre.In addition, in the closed position and in the plane P, the vertical dimension ZT of the axis T is greater than the vertical dimension Z2 of the axis A2. The axes T, A1 and A2 are arranged along the X axis in this order.

On a représenté sur la figure 9 :

  • La variation du couple C1 généré par le poids de l'ouvrant en fonction d'un angle d'ouverture de l'ouvrant. En l'espèce, l'angle valant 0 degrés en position de fermeture et 100 degrés en position d'ouverture.
  • La variation du couple C2 généré par les moyens de soutien de l'ouvrant 12 selon l'invention.
  • La variation du couple C3 généré par les équilibreurs d'un ouvrant conforme à l'état de la technique.
  • La différence du couple C1 et du couple C2 représentant le couple C4 à fournir pour ouvrir et fermer l'ouvrant 12 selon l'invention.
  • La différence du couple C1 et du couple C3 représentant le couple C5 à fournir pour ouvrir et fermer l'ouvrant conforme à l'état de la technique.
We have shown on the figure 9 :
  • The variation of the torque C 1 generated by the weight of the opening according to an opening angle of the opening. In this case, the angle is 0 degrees in the closed position and 100 degrees in the open position.
  • The variation of the torque C 2 generated by the support means of the opening 12 according to the invention.
  • The variation of the torque C 3 generated by the balancers of an opening according to the state of the art.
  • The difference between the torque C 1 and the torque C 2 represents the torque C 4 to be provided to open and close the opening 12 according to the invention.
  • The difference between the torque C 1 and the torque C 3 representing the torque C 5 to be supplied to open and close the sash according to the state of the art.

Chaque couple C1, C2, C3 croit sur une plage de position successives depuis la position de fermeture jusque dans une position intermédiaire, puis décroît depuis cette position intermédiaire jusque dans la position d'ouverture. Chaque position intermédiaire correspondant à chaque couple C1, C2, C3 est respectivement référencée I1, I2 et I3. Les moyens de soutien 32 sont illustrés dans la position intermédiaire I2 de l'ouvrant 12 à la figure 6.Each pair C 1 , C 2 , C 3 increases over a range of successive positions from the closed position to an intermediate position, then decreases from this intermediate position into the open position. Each intermediate position corresponding to each pair C 1 , C 2 , C 3 is respectively referenced I 1 , I 2 and I 3 . The support means 32 are illustrated in the intermediate position I 2 of the opening 12 to the figure 6 .

En outre, le couple C2 est inférieur au couple C1 sur une plage de positions successives depuis la position de fermeture de l'ouvrant 12 jusque dans une position commune E1,2 dans laquelle les couples C1 et C2 sont égaux. Le couple C2 est supérieur au couple 1 depuis la position commune E1,2 jusque dans la position d'ouverture de l'ouvrant 12.In addition, the torque C 2 is less than the torque C 1 over a range of successive positions from the closing position of the opening 12 to a common position E 1,2 in which the pairs C 1 and C 2 are equal. The torque C 2 is greater than the torque 1 from the common position E 1.2 to the open position of the opening 12.

De façon analogue, le couple 3 est inférieur au couple 1 sur une plage de positions successives depuis la position de fermeture jusque dans une position commune E1,3 dans laquelle les couples 1 et 3 sont égaux. Le couple 3 est supérieur au couple 1 depuis la position commune E1,3 jusque dans la position d'ouverture.Similarly, the torque 3 is less than the torque 1 over a range of successive positions from the closed position to a common position E 1.3 in which the pairs 1 and 3 are equal. The torque 3 is greater than the torque 1 from the common position E 1.3 to the open position.

La valeur du couple C4 entre la position de fermeture et la position commune étant négative, la valeur du couple C4 est donc la valeur du couple à fournir par un utilisateur pour ouvrir l'ouvrant. Le couple C4 à fournir par l'utilisateur pour ouvrir l'ouvrant 12 selon l'invention depuis la position de fermeture jusque dans la position commune E1,2 est plus petit que le couple à fournir par cet utilisateur pour ouvrir l'ouvrant de l'état de la technique depuis la position de fermeture jusque dans la position commune E1,3. L'ouvrant selon l'invention est donc relativement facile à ouvrir.The value of the torque C 4 between the closed position and the common position being negative, the value of the torque C 4 is therefore the value of the torque to be supplied by a user to open the opening. The torque C 4 to be supplied by the user to open the opening 12 according to the invention from the closed position to the common position E 1.2 is smaller than the torque to be supplied by this user to open the opening from the state of the art from the closed position to the common position E 1.3 . The opening according to the invention is relatively easy to open.

La valeur du couple C5 entre la position de fermeture et la position commune étant positive, la valeur du couple C5 est donc la valeur du couple à fournir par un utilisateur pour fermer l'ouvrant. Le couple C5 à fournir par l'utilisateur pour fermer l'ouvrant 12 selon l'invention depuis la position d'ouverture jusque dans la position commune E1,2 est plus petit que le couple à fournir par cet utilisateur pour fermer l'ouvrant de l'état de la technique depuis la position d'ouverture jusque dans la position commune E1,3. L'ouvrant selon l'invention est donc relativement facile à fermer.Since the value of the torque C 5 between the closed position and the common position is positive, the value of the torque C 5 is therefore the value of the torque to be supplied by a user to close the door. The torque C 5 to be supplied by the user to close the opening 12 according to the invention from the open position to the common position E 1,2 is smaller than the torque to be supplied by this user to close the door. opening of the state of the technique from the open position to the common position E 1.3 . The opening according to the invention is relatively easy to close.

On a représenté sur la figure 10 un véhicule comprenant un ouvrant selon un deuxième mode de réalisation de l'invention. Les éléments analogues à ceux représentés sur les figures précédentes sont désignés par des références identiques.We have shown on the figure 10 a vehicle comprising an opening according to a second embodiment of the invention. Elements similar to those shown in the preceding figures are designated by identical references.

A la différence de l'ouvrant 12 selon le premier mode de réalisation, les moyens de traction 43 comprennent deux éléments élastiquement déformables 38a, 38b, en l'espèce deux ressorts 39a, 39b. Chaque ressort 39a, 39b est déformable entre :

  • une première position d'allongement dans laquelle chaque ressort 39a, 39b présente une première longueur d'allongement correspondant à la position de fermeture de l'ouvrant 12, et
  • une deuxième position d'allongement dans laquelle chaque ressort 39a, 39b présente une deuxième longueur d'allongement inférieure à la première et correspondant à la position d'ouverture de l'ouvrant 12.
Unlike the opening 12 according to the first embodiment, the traction means 43 comprise two elastically deformable elements 38a, 38b, in this case two springs 39a, 39b. Each spring 39a, 39b is deformable between:
  • a first elongation position in which each spring 39a, 39b has a first elongation length corresponding to the closing position of the opening 12, and
  • a second extension position in which each spring 39a, 39b has a second length of elongation less than the first and corresponding to the open position of the opening 12.

Les premiers moyens de liaison 34 des moyens de soutien 32 à la caisse 14 comprennent deux liaisons rotules 60, 62 matérialisant l'axe géométrique A1.The first connection means 34 of the support means 32 to the body 14 comprise two ball joints 60, 62 embodying the geometric axis A1.

Les moyens de soutien 32 de l'ouvrant 12 comprennent deux axes 40a, 40b portés par l'ouvrant 12, en l'espèce fixés à l'ouvrant 12, par exemple par des vis ou par soudure. Les axes 40a, 40b sont donc fixes par rapport à l'ouvrant 12. Chaque ressort 39a, 39b est comprimé ou étiré respectivement lorsqu'un utilisateur ouvre ou ferme l'ouvrant 12. Les moyens de soutien 32 comprennent également deux éléments 41, 42 aptes à coulisser respectivement le long des axes 40a, 40b autour desquels ils sont chacun aptes à pivoter autour de l'axe géométrique A2. Chaque axe 40a, 40b comprend respectivement une butée 44, 46 de limitation du déplacement axial respectivement de chaque élément 41, 42 sur chaque axe 40a, 40b.The support means 32 of the opening 12 comprise two axes 40a, 40b carried by the opening 12, in this case attached to the opening 12, for example by screws or welding. The axes 40a, 40b are therefore fixed relative to the opening 12. Each spring 39a, 39b is compressed or stretched respectively when a user opens or closes the opening 12. The support means 32 also comprise two elements 41, 42 capable of sliding respectively along the axes 40a, 40b around which they are each able to pivot about the geometric axis A2. Each axis 40a, 40b respectively comprises a stop 44, 46 for limiting the axial displacement respectively of each element 41, 42 on each axis 40a, 40b.

Chaque organe 48, 50 est fixé, d'une part à la caisse par la liaison rotule 60, 62 et, d'autre part, à l'élément 41, 42 par une liaison pivot. Ainsi, chaque organe 48, 50 est apte à exercer une force de poussée sur la caisse à laquelle il est fixé et par réaction, provoquer le soutien de l'ouvrant 12.Each member 48, 50 is fixed on the one hand to the body by the ball joint 60, 62 and, on the other hand, to the element 41, 42 by a pivot connection. Thus, each member 48, 50 is able to exert a thrust force on the body to which it is attached and by reaction, cause the support of the opening 12.

La figure 11 illustre les axes T, A1, A2 dans la position de fermeture de l'ouvrant 12 et dans le plan vertical longitudinal P du véhicule 10.The figure 11 illustrates the axes T, A1, A2 in the closed position of the opening 12 and in the longitudinal vertical plane P of the vehicle 10.
