Description

Dispositif d'occultation d'une baie vitrée actionné par un élément gonflable  Device for concealing a bay window operated by an inflatable element
[01] La présente invention concerne le domaine technique des dispositifs d'occultation d'une baie vitrée de véhicule utilisés notamment afin d'arrêter une partie au moins du rayonnement solaire traversant la vitre de la baie. [01] The present invention relates to the technical field of occultation devices of a vehicle bay window used in particular to stop at least a portion of solar radiation passing through the window of the bay.
[02] Dans le domaine ci-dessus, il est connu de mettre en uvre, dans le cadre des véhicules automobiles notamment, des stores d'occultation qui sont stockées sur un enrouleur à ressorts et qui sont déroulées manuellement afin d'occulter en partie les baies vitrées qu'ils équipent. De tels systèmes présentent l'inconvénient de ne pas pouvoir être motorisés facilement. [02] In the above field, it is known to implement, in the context of motor vehicles in particular, shading blinds which are stored on a spring winder and which are unwound manually to obscure part of the windows they equip. Such systems have the disadvantage of not being able to be motorized easily.
[03] Il est également connu, pour l'occultation de toits vitrés de véhicule, des rideaux motorisés qui se déplacent le long de rails intégrés dans le plafond du véhicule. De tels rideaux motorisés permettent effectivement une commande à distance sans manœuvre manuelle mais présentent l'inconvénient de nécessiter des systèmes de guidage et de manœuvre par câbles, complexes et onéreux ainsi que relativement lourds. [03] It is also known, for the concealment of glazed vehicle roofs, motorized curtains that move along integrated rails in the ceiling of the vehicle. Such motorized curtains effectively allow remote control without manual maneuver but have the disadvantage of requiring guide systems and maneuvering cables, complex and expensive and relatively heavy.
[04] Il est donc apparu le besoin d'un nouveau type de dispositif d'occultation dont la manœuvre puisse être effectuée à distance de manière simple et légère sans nécessiter d'un complexe système de manœuvre par câble. [04] It has therefore emerged the need for a new type of concealment device which can be maneuvered remotely in a simple and light manner without the need for a complex cable maneuvering system.
[05] Afin d'atteindre cet objectif l'invention concerne un dispositif d'occultation d'une baie vitrée comprenant un châssis supportant un rideau qui mobile entre une position de rétraction et une position d'occultation et qui comprend au moins un élément gonflable intégré au rideau et adapté pour, lors de son gonflage, déplacer le rideau mobile en position d'occultation et, lors de son dégonflage, déplacer le rideau mobile en position de rétraction.  [05] In order to achieve this object, the invention relates to an obscuration device of a bay window comprising a frame supporting a curtain which is movable between a retracted position and an occultation position and which comprises at least one inflatable element. integrated in the curtain and adapted to, when inflated, move the movable curtain in the occultation position and, when deflating, move the movable curtain retracted position.
[06] Selon l'invention, l'élément gonflable comprend une enveloppe creuse souple comportant :  [06] According to the invention, the inflatable element comprises a flexible hollow envelope comprising:
- un panneau arrière destiné à être placé vers la baie vitrée,  - a rear panel intended to be placed towards the bay window,
- un panneau avant situé à l'opposé du panneau arrière et destiné à être placé à l'opposé de la baie vitrée,  - a front panel located opposite the rear panel and intended to be placed opposite the bay window,
et le dispositif d'occultation comprend en outre : and the concealment device further comprises:
- une barre de charge liée aux panneaux avant et arrière de l'élément gonflable, a load bar connected to the front and rear panels of the inflatable element,
- des moyens de guidage en translation de la barre de charge, au moins, qui est déplacée en translation par l'élément gonflable entre : - une position repliée dans laquelle le rideau est replié en position de rétraction, la barre de charge étant à proximité du châssis, means for guiding in translation of the load bar, at least, which is displaced in translation by the inflatable element between: a folded position in which the curtain is folded into the retracted position, the load bar being close to the chassis,
- une position dépliée dans laquelle rideau est déplié en position d'occultation, la barre de charge étant éloignée du châssis.  - An unfolded position in which the curtain is unfolded in the occultation position, the load bar being away from the frame.
[07] La mis en œuvre d'un élément gonflable associé à la barre de charge permet d'assurer le déploiement et la rétraction du rideau par un mouvement de translation de manière simple sans câble de commande. [07] The implementation of an inflatable element associated with the load bar ensures the deployment and retraction of the curtain by a translation movement in a simple manner without control cable.
[08] Selon une caractéristique de l'invention, le dispositif d'occultation comprend au moins une nervure rigide qui est liée aux panneaux avant et/ou arrière de l'élément gonflable. La mise en ouvre d'une telle nervure rigide permet notamment de conformer l'élément gonflable de manière que son panneau arrière possède une forme complémentaire de celle de la vitre de la baie. De plus, la nervure rigide évite que les panneaux avant et arrière ne viennent en contact l'un avec l'autre lors du dégonflage par aspiration de l'air contenu dans l'élément gonflable. Chaque nervure rigide peut de plus comprendre des extensions assurant le maintient des parties du rideau qui ne sont pas formées par le ou les éléments gonflables.  According to one characteristic of the invention, the concealment device comprises at least one rigid rib which is connected to the front and / or rear panels of the inflatable element. The implementation of such a rigid rib allows in particular to conform the inflatable element so that its rear panel has a shape complementary to that of the window of the bay. In addition, the rigid rib prevents the front and rear panels from coming into contact with each other during vacuum deflation of the air contained in the inflatable element. Each rigid rib may further comprise extensions ensuring the maintenance of the parts of the curtain that are not formed by the or inflatable elements.
[09] Selon une variante de cette caractéristique, le dispositif d'occultation comprend plusieurs nervures rigides qui sont chacune liées aux panneaux avant et/ou arrière de l'élément gonflable et qui sont distantes les unes des autres lorsque le rideau est en position d'occultation. La répartition des nervures rigides permet de bien maîtriser la forme du rideau en position d'occultation ainsi que le dégonflage de chaque élément gonflable. Les nervures rigides sont, de manière préférée, sensiblement parallèles entre elles lorsque le mouvement du rideau se fait en translation. Toutefois une autre disposition des nervures rigides est envisageable. Ainsi, lorsque le rideau se déploie à la manière d'un éventail, les nervures rigides sont disposées de manière à converger dans une même direction.  [09] According to a variant of this feature, the concealment device comprises a plurality of rigid ribs which are each connected to the front and / or rear panels of the inflatable element and which are distant from each other when the curtain is in position d occultation. The distribution of rigid ribs makes it possible to control the shape of the curtain in the occultation position as well as the deflation of each inflatable element. The rigid ribs are, preferably, substantially parallel to each other when the movement of the curtain is in translation. However another arrangement of rigid ribs is possible. Thus, when the curtain unfolds in the manner of a fan, the rigid ribs are arranged so as to converge in the same direction.
[10] Selon une autre variante de cette caractéristique, chaque nervure rigide est située à l'intérieur de l'enveloppe de l'élément gonflable.  [10] According to another variant of this characteristic, each rigid rib is located inside the envelope of the inflatable element.
[11] Dans le cadre de cette variante, certaines nervures rigides au moins peuvent alors comprendre des ouvertures de passage de l'air de gonflage.  [11] In the context of this variant, at least some rigid ribs may then include openings for the passage of inflation air.
[12] Selon une autre caractéristique de l'invention, certaines nervures rigides présentent, en section droite transversale, une forme en partie au moins convexe et/ou concave. Une telle forme des nervures permet de définir un espace de guidage pour les plis des panneaux de l'élément gonflable en position de rétraction sans augmenter la distance entre les panneaux avant et arrière en position d'extension du rideau lorsque l'élément gonflable est gonflé. According to another characteristic of the invention, certain rigid ribs have, in transverse cross-section, a shape that is at least partly convex and / or concave. Such a shape of the ribs makes it possible to define a guiding space for the folds of the panels of the inflatable element in the retracted position without increasing the distance between the front and rear panels in the extension position of the curtain when the inflatable element is inflated. .
[13] Selon encore une autre caractéristique de l'invention, l'élément gonflable s'étend sur toute la surface du rideau. La mise en œuvre d'un tel élément gonflable qui s'étant sur toute la surface du rideau permet d'assurer une meilleure isolation thermique au niveau de la baie vitrée. [13] According to yet another feature of the invention, the inflatable member extends over the entire surface of the curtain. The implementation of such an inflatable element which is over the entire surface of the curtain ensures better thermal insulation at the bay window.
[14] Selon l'invention, les moyens de guidage peuvent être réalisés de toute manière appropriée. Ainsi, selon une première forme de réalisation de l'invention, les moyens de guidage comprennent au moins une barre fixe de guidage de la barre de charge. Une telle barre fixe de guidage peut alors être située à l'extérieur de l'élément gonflable. Selon une variante de cette forme de réalisation la barre fixe de guidage s'étend en partie au moins à l'intérieur de l'élément gonflable. La barre de guidage peut alors traverser la barre de charge ainsi que l'enveloppe constitutive de l'élément sans qu'il soit nécessaire d'assurer l'étanchéité à ce niveau. Dans ce cas, le système de gonflage possède un débit de gonflage supérieur au débit de fuite au niveau de la ou des traversée de l'élément gonflable par les moyens de guidage.  [14] According to the invention, the guide means can be made in any suitable manner. Thus, according to a first embodiment of the invention, the guide means comprise at least one fixed bar for guiding the load bar. Such a fixed guide bar may then be located outside the inflatable element. According to a variant of this embodiment, the fixed guide bar extends in part at least inside the inflatable element. The guide bar can then cross the load bar and the constituent envelope of the element without the need to ensure sealing at this level. In this case, the inflation system has an inflation rate greater than the leakage rate at the passage (s) of the inflatable element by the guide means.
[15] Selon une deuxième forme de réalisation de l'invention, les moyens de guidage comprennent une armature articulée :  [15] According to a second embodiment of the invention, the guide means comprise an articulated armature:
- qui est liée au châssis,  - which is linked to the chassis,
- qui porte à l'opposé du châssis une barre de charge liée au rideau,  - which, opposite the chassis, has a load bar connected to the curtain,
- et qui mobile entre :  - and who moves between:
- une position repliée dans laquelle le rideau est en position de rétraction, la barre de charge étant à proximité du châssis,  a folded position in which the curtain is in the retracted position, the load bar being close to the chassis,
- une position dépliée dans laquelle rideau est en position d'occultation, la barre de charge étant éloignée du châssis.  - An unfolded position in which the curtain is in the occultation position, the load bar being away from the frame.
[16] La mise en œuvre d'une telle armature articulée permet de faciliter les mouvements du rideau entre ses positions d'occultation et de rétraction. Ainsi, il n'est pas nécessaire de mettre en œuvre une structure externe pour assurer le guidage du rideau ce qui en facilite l'installation et en diminue donc le coût.  [16] The implementation of such an articulated frame facilitates the movement of the curtain between its positions of concealment and retraction. Thus, it is not necessary to implement an external structure for guiding the curtain which facilitates installation and therefore reduces the cost.
[17] [18] Selon une autre caractéristique de l'invention, l'armature articulée est située à l'intérieur de l'enveloppe de l'élément gonflable. Un tel positionnement de l'armature rigide permet de la protéger et de la dissimuler au regard afin d'offrir une esthétique satisfaisante au dispositif d'occultation selon l'invention. [17] [18] According to another characteristic of the invention, the hinged armature is located inside the envelope of the inflatable element. Such a positioning of the rigid frame makes it possible to protect it and conceal it from view in order to offer a satisfactory aesthetic to the concealment device according to the invention.
[19] Selon encore une autre caractéristique de l'invention, chaque nervure rigide comprend une fenêtre de passage de l'armature articulée. [19] According to yet another feature of the invention, each rigid rib comprises a passage window of the hinged armature.
[20] Selon une caractéristique de l'invention, l'armature articulée est articulée sur certaines au moins des nervures rigides.  [20] According to a feature of the invention, the articulated armature is articulated on at least some rigid ribs.
[21] Selon une autre caractéristique de l'invention, certaines au moins des nervures rigides font partie intégrante de la structure articulée de sorte que l'armature articulée est en partie au moins formée par des nervures rigides.  According to another characteristic of the invention, at least some rigid ribs are an integral part of the articulated structure so that the articulated armature is partly formed by at least rigid ribs.
[22] Selon une caractéristique de l'invention, le dispositif d'occultation comprend des moyens de gonflage motorisés adaptés pour gonfler et dégonfler l'élément gonflable.  According to one characteristic of the invention, the concealment device comprises motorized inflation means adapted to inflate and deflate the inflatable element.
[23] Bien entendu, les différentes caractéristiques, variantes et formes de réalisation de l'invention peuvent être associées les unes avec les autres selon diverses combinaisons dans la mesure où elles ne sont pas incompatibles ou exclusives les unes des autres. [23] Of course, the various features, variations and embodiments of the invention may be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other.
[24] Par ailleurs, diverses autres caractéristiques de l'invention ressortent de la description annexée effectuée en référence aux dessins qui illustrent des forment non limitatives de réalisation d'un dispositif, conforme à l'invention, d'occultation d'une baie vitrée. [24] Furthermore, various other features of the invention appear from the attached description with reference to the drawings which illustrate non-limiting embodiments of a device according to the invention for concealment of a bay window .

[25] Il est à noter que sur ces figures les éléments structurels et/ou fonctionnels communs aux différentes variantes peuvent présenter les mêmes références.  [25] It should be noted that in these figures the structural and / or functional elements common to the different variants may have the same references.
[26] Un dispositif d'occultation selon l'invention, tel qu'illustré aux figures 1 à 3, est destiné à assurer une occultation temporaire et au moins partielle d'une baie vitrée B telle que par exemple une fenêtre latérale de véhicule, un pare-brise ou encore une lunette arrière. Il est à noter que si le dispositif d'occultation selon l'invention trouve une application préférée dans l'occultation des baies de véhicules, il peut également être utilisé pour occultation de baies vitrées de bâtiments.  [26] A concealment device according to the invention, as illustrated in FIGS. 1 to 3, is intended to ensure a temporary and at least partial occultation of a bay window B such as for example a vehicle side window, a windshield or a rear window. It should be noted that if the concealment device according to the invention finds a preferred application in the concealment of vehicle bays, it can also be used for concealment of windows of buildings.
[27] Le dispositif d'occultation comprend un châssis 1 qui supporte un rideau 2 mobile entre une position de rétraction R, illustrée à la figure 1, et une position d'occultation 0 qui est montrée aux figures 2 et 3 et dans laquelle le rideau 2 occulte en partie au moins la baie B. Le châssis 1 est destiné à être intégré à la structure porteuse de la baie ou à être rapporté sur cette structure porteuse. Le rideau 2 comprend au moins un élément gonflable 3 qui est raccordé à des moyens de gonflage 4 adaptés pour insuffler ou aspirer de l'air dans l'élément gonflable 3. Ce dernier est alors adapté pour, lors de son gonflage, déplacer le rideau mobile 2 en position d'occultation et, lors de son dégonflage, déplacer le rideau mobile en position de rétraction R. Les moyens de gonflage 4 comprennent, par exemple, une pompe électrique réversible 5 qui est raccordée par une canalisation 6 à l'élément gonflable 3. La canalisation 6 est alors commandée par une vanne 7 qui est ouverte, lorsque la pompe 5 fonctionne, et fermée lorsque cette dernière est arrêtée. Ainsi, selon le sens de fonctionnement de la pompe 5, les moyens de gonflage 4 assurent le remplissage ou la vidange en air de l'élément gonflable 3. La pompe 5 peut être située à proximité immédiate du châssis 1 voire être intégrée au châssis 1 ou au contraire être situé à distance du châssis 1 en étant raccordé à l'élément gonflable 3 par la canalisation 6. [27] The concealment device comprises a frame 1 which supports a curtain 2 movable between a retraction position R, illustrated in FIG. 1, and a concealment position 0 which is shown in FIGS. 2 and 3 and in which the curtain 2 at least partially obscures the bay B. The frame 1 is intended to be integrated into the carrier structure of the bay or to be attached to this supporting structure. The curtain 2 comprises at least one inflatable element 3 which is connected to inflating means 4 adapted to insufflate or suck air into the inflatable element 3. The latter is then adapted to, during its inflation, move the curtain 2 in the occultation position and, when deflating, move the movable curtain retracted position R. The inflation means 4 comprise, for example, a reversible electric pump 5 which is connected by a pipe 6 to the element Inflatable 3. The pipe 6 is then controlled by a valve 7 which is open when the pump 5 is operating, and closed when the latter is stopped. Thus, depending on the direction of operation of the pump 5, the inflation means 4 ensure the filling or the air discharge of the inflatable element 3. The pump 5 can be located in the immediate vicinity of the chassis 1 or be integrated into the chassis 1 or on the contrary be located away from the frame 1 by being connected to the inflatable element 3 by the pipe 6.
[28] Selon l'invention, le rideau 2 peut comprendre un ou plusieurs éléments gonflables occupant une partie seulement de sa surface. Selon l'exemple illustré, l'élément gonflable 3 s'étend sur toute surface du rideau 2 de sorte que ce dernier peut être qualifié dans son ensemble de rideau gonflable.  [28] According to the invention, the curtain 2 may comprise one or more inflatable elements occupying only part of its surface. According to the illustrated example, the inflatable element 3 extends over any surface of the curtain 2 so that the latter can be qualified in its overall curtain airbag.
[29] L'élément gonflable 3, constitutifs du rideau 2 dans le cas présent, est formé par une enveloppe qui comprend un panneau arrière 10 destiné à être placé vers la baie vitrée B et un panneau avant le 11 situés à l'opposé du panneau arrière 10 et destiné à être placé à l'opposé de la baie vitrée B. L'élément gonflable 3 comprend également deux panneaux latéraux 12 et un panneau inférieur 13 qui relient les panneaux avant 11 et arrière 10. L'élément gonflable est en outre raccordé, à l'opposé du panneau inférieur 13, de manière étanche au châssis 1 qui assure une fonction de boîte de distribution assurant une répartition de l'air sur toute la longueur du châssis 1. L'enveloppe constitutive de l'élément gonflable 3 peut être réalisée en tout matériau étanche à l'air approprié. Ainsi, l'enveloppe peut être réalisée en un film de matière plastique multicouche comprenant une feuille d'un matériau réfléchissant tel que l'aluminium de manière à réfléchir une partie du rayonnement solaire pour réduire l'effet de serre à l'intérieur du véhicule lorsque le rideau 2 est en position d'occultation O. Par ailleurs, il doit être remarqué que caractère gonflable du rideau 2 lui permet de constituer un élément d'isolation de la baie vitrée B lorsqu'il est en position d'occultation. Il doit être noté que l'étanchéité à l'air de l'enveloppe n'est pas nécessairement totale et que cette dernière peut présenter un ou plusieurs points de fuite.  [29] The inflatable element 3, constituent of the curtain 2 in this case, is formed by an envelope which comprises a rear panel 10 intended to be placed towards the bay window B and a front panel 11 located opposite the rear panel 10 and intended to be placed opposite the bay window B. The inflatable element 3 also comprises two side panels 12 and a lower panel 13 which connect the front panels 11 and rear 10. The inflatable element is in position. further connected, opposite the lower panel 13, sealingly to the frame 1 which provides a distribution box function ensuring a distribution of air over the entire length of the frame 1. The envelope constituting the inflatable element 3 can be made of any suitable airtight material. Thus, the envelope may be made of a multilayer plastic film comprising a sheet of a reflective material such as aluminum so as to reflect a portion of the solar radiation to reduce the greenhouse effect inside the vehicle when the curtain 2 is in occultation position O. Furthermore, it should be noted that inflatable character of the curtain 2 allows it to constitute an insulation element of the bay window B when it is in the occultation position. It should be noted that the airtightness of the envelope is not necessarily total and that the latter may have one or more vanishing points.
[30] Selon l'exemple illustré, afin de faciliter le dégonflage et d'éviter que l'élément gonflable ne forme une fois gonflée des ventres trop importants, le dispositif d'occultation comprend au moins une et, selon l'exemple illustré, huit nervures rigides 15 qui sont chacune liées aux panneaux avant 11 et arrière 10 de l'élément gonflable 3. Chaque nervure rigide 15 présente une forme sensiblement rectangulaire, comme cela ressort de la figure 4. Chaque nervure 15 est constituée par un flanc de matière plastique de faible épaisseur. Les nervures rigides 15 sont disposées à l'intérieur de l'enveloppe 3 avec leurs bords longitudinaux 16 soudés ou collés aux panneaux avant 11 et arrière 10 de sorte que les nervures 15 définissent des caissons à l'intérieur de l'enveloppe 3. Afin de permettre une bonne circulation de l'air à l'intérieur de l'élément gonflable 3 et d'un caisson à l'autre, chaque nervure 15 comprend des ouvertures 17 de passage de l'air de gonflage. Les nervures rigides 15 sont disposées de manière sensiblement parallèle les unes aux autres tout en étant réparties à l'intérieur de l'enveloppe 3 lorsque le rideau 2 est en position d'occultation 0. [30] According to the illustrated example, in order to facilitate deflation and prevent the inflatable element once inflated too large bellies, the concealment device comprises at least one and, according to the illustrated example, eight rigid ribs 15 which are each connected to the front panels 11 and rear 10 of the inflatable element 3. Each rigid rib 15 has a substantially rectangular shape, as is apparent from Figure 4. Each rib 15 is constituted by a flank of material thin plastic. The rigid ribs 15 are disposed inside the casing 3 with their longitudinal edges 16 welded or glued to the front panels 11 and rear 10 so that the ribs 15 define casings inside the casing 3. to allow a good flow of air inside the inflatable element 3 and a box to another, each rib 15 comprises openings 17 for the passage of inflation air. The rigid ribs 15 are arranged substantially parallel to each other while being distributed inside the casing 3 when the curtain 2 is in the occulting position 0.
[31] Les nervures rigides 15 évitent donc que les panneaux avant 11 et arrière 10 ne soient trop éloignés et ne forment des ventres lorsque que l'élément gonflable 3 est gonflé. De plus, les nervures rigides 15 évitent que les panneaux avant 11 et arrière 10 ne se collent l'un contre l'autre sous l'effet de la pression atmosphérique lorsque l'air est aspiré hors de l'élément gonflable3 afin de ramener le rideau 2 en position de rétraction R. En effet un tel contact entre les panneaux avant 11 et arrière 10 de l'élément gonflable 3 serait susceptible de faire obstacle à un dégonflage complet de ce dernier.  [31] The rigid ribs 15 therefore prevent the front panels 11 and rear 10 are too far apart and form bellies when the inflatable element 3 is inflated. In addition, the rigid ribs 15 prevent the front panels 11 and rear 10 from sticking against each other under the effect of atmospheric pressure when the air is sucked out of the inflatable element3 in order to reduce the pressure. curtain 2 retracted position R. Indeed, such contact between the front panels 11 and rear 10 of the inflatable element 3 would be likely to prevent complete deflation of the latter.
[32] Selon l'exemple illustré le dispositif d'occultation comprend également, en tant que moyens de guidage, une armature articulée 20 qui est liée au châssis 1. L'armature articulée 20 porte, à l'opposé du châssis 1, une barre de charge 21 qui est liée au rideau 2 et plus particulièrement aux panneaux avant 11 et arrière 10 en partie basse de ces derniers. Dans le cas présent, l'armature articulée 20 est disposée à l'intérieur de l'élément gonflable 3 en passant dans des fenêtres 22 aménagées à cet effet dans chacune des nervures rigides 15. L'armature articulée 20 comprend deux bras 23 formés de deux segments 24, 25 articulés ensemble. Un premier segment 24 est en outre articulé sur le châssis 1 tandis que le deuxième segment 25 est articulé sur la barre de charge 21.  [32] According to the illustrated example the concealment device also comprises, as guide means, an articulated frame 20 which is connected to the frame 1. The articulated frame 20 carries, opposite the frame 1, a load bar 21 which is linked to the curtain 2 and more particularly to the front panels 11 and rear 10 at the bottom of the latter. In the present case, the hinged armature 20 is disposed inside the inflatable element 3 by passing through windows 22 provided for this purpose in each of the rigid ribs 15. The hinged armature 20 comprises two arms 23 formed of two segments 24, 25 articulated together. A first segment 24 is further articulated on the frame 1 while the second segment 25 is articulated on the load bar 21.
[33] Le dispositif d'occultation tel qu'ainsi constitué fonctionne de la manière suivante. [33] The concealment device as thus constituted operates in the following manner.
[34] À partir de la position de rétraction R telle qu'illustrée à la figure 1, lorsque le déploiement du rideau 2 est souhaité, le fonctionnement de la pompe 5 et l'ouverture la vanne 7 sont commandés de manière à souffler de l'air à l'intérieur de l'élément gonflable 3. Ce gonflage contribue à une mise en volume de l'élément gonflable 3 de manière à amener le rideau 2 dans sa position d'occultation O telle qu'illustrée à la figure 2. [34] From the retraction position R as illustrated in FIG. 1, when the deployment of the curtain 2 is desired, the operation of the pump 5 and the opening of the valve 7 are controlled so as to blow the air. air inside the inflatable element 3. This inflation contributes to a volume of the inflatable element 3 so as to bring the curtain 2 in its occultation position O as illustrated in Figure 2.
[35] Une fois le gonflage terminé, la pompe 5 est arrêtée et la fermeture de la vanne 7 est commandée. Ainsi, l'élément gonflable 3 reste en position gonflée et maintient le rideau 2 dans son état d'occultation. La fermeture de la vanne 7 permet d'éviter un dégonflage spontané de l'élément gonflable 3 et cela notamment lorsque que l'armature articulée comprend des moyens de rappel en position repliée. [35] Once the inflation is completed, the pump 5 is stopped and the closing of the valve 7 is controlled. Thus, the inflatable element 3 remains in the inflated position and keeps the curtain 2 in its state of occultation. Closing the valve 7 makes it possible to avoid a spontaneous deflation of the inflatable element 3 and this especially when the articulated armature comprises return means in the folded position.
[36] Lorsqu'une rétraction du rideau 2 est souhaitée afin de dégager la vue au travers de la baie vitrée B, il est commandé une ouverture de la vanne 7 ainsi qu'un fonctionnement de la pompe 5 en aspiration afin d'évacuer l'air contenu dans l'élément gonflable 3. La dépression ainsi créée dans l'élément gonflable 3 tend à replier vers l'intérieur les panneaux de ce dernier comme le montre la figure 5, les nervures rigides 15 permettent alors de maîtriser ce repliement en empêchant les panneaux de venir en contact les uns avec les autres de sorte que l'air peut être complètement évacué de l'intérieur de l'enveloppe en passant par les ouvertures 15 et les fenêtres 22. De plus, l'armature articulée qui passe à l'intérieur des fenêtres 22 empêche que les nervures rigides 15 se placent en travers de sorte que le rideau 2 peut se replier progressivement jusqu'à sa position de rétraction. En position de rétraction l'élément gonflable et le rideau donc, sont repliés sur eux-mêmes en accordéon à la manière du soufflet d'un tel accordéon.  [36] When a retraction of the curtain 2 is desired to clear the view through the bay window B, it is controlled an opening of the valve 7 and a functioning of the pump 5 in suction to evacuate the air in the inflatable element 3. The depression thus created in the inflatable element 3 tends to fold inward the panels of the latter as shown in Figure 5, the rigid ribs 15 can then control this folding in preventing the panels from coming into contact with each other so that air can be completely removed from the interior of the envelope through openings 15 and windows 22. In addition, the hinged armature that passes inside the windows 22 prevents the rigid ribs 15 from moving across so that the curtain 2 can gradually fold back to its retracted position. In the retracted position the inflatable element and the curtain therefore, are folded on themselves in accordion in the manner of the bellows of such an accordion.
[37] Selon l'exemple illustré et décrit précédemment, l'armature articulée 20 passe à l'intérieur des nervures rigides 15 sans d'être directement articulée sur ces dernières. Toutefois, comme le montre la figure 6, l'armature articulée peut comprendre des segments 30 articulés directement sur les nervures rigides 15 qui font alors partie intégrante de l'armature articulée 20. [37] According to the example illustrated and described above, the articulated armature 20 passes inside the rigid ribs 15 without being directly articulated on the latter. However, as shown in FIG. 6, the articulated armature may comprise segments articulated directly on the rigid ribs 15 which then form an integral part of the articulated armature 20.
[38] Par ailleurs, selon l'invention la structure de l'armature articulée peut être réalisée de différentes manières et ne comprend pas nécessairement des bras articulés à deux segments comme décrit précédemment. Ainsi, l'armature articulée peut comprendre un système de pantographe comme cela est illustré à la figure 7. Il doit être noté que selon cet exemple le rideau 2 est adapté pour se déployer selon une trajectoire sensiblement horizontale alors que selon l'exemple décrit en relation avec les figures 1 à 5 le mouvement du rideau se fait selon une direction sensiblement verticale. De plus, selon l'exemple de la figure 7 le rideau possède une forme générale trapézoïdale particulièrement adaptée à une fenêtre latérale de véhicule. [38] Furthermore, according to the invention the structure of the articulated armature can be made in different ways and does not necessarily include articulated arms with two segments as described above. Thus, the articulated armature may comprise a pantograph system as illustrated in FIG. 7. It should be noted that according to this example the curtain 2 is adapted to deploy in a substantially horizontal trajectory whereas according to the example described in FIG. relationship with Figures 1 to 5 the movement of the curtain is in a substantially vertical direction. In addition, according to the example of Figure 7 the curtain has a generally trapezoidal shape particularly suitable for a vehicle side window.
[39] La figure 8 illustre une autre variante de réalisation selon laquelle les segments articulés 24 et 25 de l'armature articulée 20 comprennent des articulations 35 coniques permettant au rideau 2 du dispositif d'occultation selon l'invention de former un angle lorsqu'il est en position d'occultation comme cela est montré. [40] Selon l'exemple de réalisation de l'illustré aux figures 1 à 5 et décrit précédemment, chaque nervure rigide présente, en vue de dessus, une forme sensiblement rectangulaire. Toutefois, une telle forme n'est pas strictement nécessaire. En effet, chaque nervure rigide 15 peut présenter une forme différente de manière à suivre la forme de la baie vitrée que le rideau 2 doit occulter. Ainsi, la figure 9 montre un exemple de nervure rigide dont la forme est adaptée à l'occultation d'une baie vitrée concave comme par exemple un pare-brise de véhicule. [39] FIG. 8 illustrates another variant embodiment in which the articulated segments 24 and 25 of the hinged armature 20 comprise conical joints allowing the curtain 2 of the concealment device according to the invention to form an angle when it is in the occultation position as shown. [40] According to the embodiment of the illustrated in Figures 1 to 5 and described above, each rigid rib has, in top view, a substantially rectangular shape. However, such a form is not strictly necessary. Indeed, each rigid rib 15 may have a different shape to follow the shape of the window that the curtain 2 must hide. Thus, Figure 9 shows an example of a rigid rib whose shape is adapted to the concealment of a concave window such as a vehicle windshield.
[41] La figure 10 illustre une autre variante de réalisation d'une nervure rigide d'un dispositif d'occultation selon l'invention. Selon cette variante la nervure rigide présente, en section de droite transversale, des parties latérales 36concaves et convexes. Ces parties latérales 36 permet de guider les plis des panneaux arrière 10 et avant 11 lors du dégonflage de l'élément gonflable 3. Ainsi, il est possible de replier une plus grande longueur de panneaux que celle qui serait possible de replier si la nervure était plate.  [41] Figure 10 illustrates another alternative embodiment of a rigid rib of a concealment device according to the invention. According to this variant the rigid rib has, in transverse cross section, concave and convex side portions 36. These lateral portions 36 guide the folds of the rear panels 10 and 11 before deflation of the inflatable element 3. Thus, it is possible to fold a longer panel length than that which would be possible to fold if the rib was flat.
[42] Selon l'exemple de réalisation illustré aux figures 1, 2 et 5, les panneau latéraux 12 et inférieur 13 de l'enveloppe constitutive de l'élément gonflable 3, sont liées aux nervures 15 ainsi qu'à la barre de charge 21. Toutefois, les panneaux latéraux et inférieur pourraient ne pas être liés aux nervures ni à la barre de charge de manière à gonfler librement pour par exemple venir en appui contre un autre rideau adjacent ou contre la structure porteuse de la baie afin en assurer une meilleure occultation. According to the exemplary embodiment illustrated in FIGS. 1, 2 and 5, the lateral panels 12 and lower 13 of the envelope constituting the inflatable element 3 are connected to the ribs 15 and to the load bar. 21. However, the side and bottom panels may not be connected to the ribs or the load bar so as to inflate freely for example abut against another adjacent curtain or against the carrier structure of the bay to ensure a better occultation.
[43] Selon les exemples décrits en relation avec les figures 1 à 7, les moyens de guidage de la barre de charge comprennent l'armature articulée 20. Toutefois un tel mode de réalisation des moyens de guidage n'est pas strictement nécessaire. Ainsi, les figures 11 et 12 illustrent un autre forme de réalisation de l'invention selon laquelle les moyens de guidage comprennent deux barres de guidage fixes 30 qui sont parallèles entre elles et à la direction de translation de la barre de charge 21. Les barres de guidage fixes 30 sont en partie au moins disposées à l'intérieur de l'élément gonflable 3 constitutif du rideau 2 et elles traversent la barre de charge 21 ainsi que les nervures 15. Il existe alors de fuites au niveau de chaque passage d'un barre de guidage 30 dans la barre de charge 21. Le débit des moyens de gonflage 4 est alors adapté pour compenser ces fuites et permettre le gonflage du rideau 2. [44] La figure 13 illustre encore une autre forme de réalisation d'un rideau conforme à l'invention, selon laquelle les nervures 15 sont articulées les unes à la suite des autres en accordéon. [43] According to the examples described with reference to FIGS. 1 to 7, the guide means of the load bar comprise the hinged armature 20. However, such an embodiment of the guide means is not strictly necessary. Thus, FIGS. 11 and 12 illustrate another embodiment of the invention according to which the guiding means comprise two fixed guide bars 30 which are parallel to each other and to the direction of translation of the load bar 21. fixed guiding guides 30 are partly at least disposed inside the inflatable element 3 constituting the curtain 2 and they pass through the load bar 21 and the ribs 15. There are then leaks at each passage of a guide bar 30 in the load bar 21. The flow of the inflation means 4 is then adapted to compensate for these leaks and allow the curtain 2 to be inflated. [44] Figure 13 illustrates yet another embodiment of a curtain according to the invention, wherein the ribs 15 are hinged one after the other accordion.
[45] Bien entendu, diverses autres modifications de l'invention peuvent être envisagées dans le cadre des revendications annexées  [45] Of course, various other modifications of the invention may be contemplated within the scope of the appended claims
