Abstract

The invention concerns a method for stowing an open top (1, 3, 5, 9) in a vehicle storage space (53). The top being initially closed, it consists in displacing the roof parts up to the inside of the storage space, some at least up to a first substantially vertically stowed position, then in displacing again said roof part(s) towards a substantially horizontal position located either in the upper part or in the lower part of the storage space (53), to clear horizontally an additional storage depth.

Description

Véhicule à toit ouvrant escamotable et procédé de rangement d'un tel toit, avec un système de basculement horizontal . La présente invention concerne un système de toit rétractable pour structure fixe ou mobile notamment pour un véhicule automobile. On connaît d'après FR 2 798 327 un système de toit rétractable pour véhicule constitué d' au moins deux panneaux de toit rigides, respectivement un premier élément de toi avant et un second élément de toit central solidarisés l'un à l'autre par des moyens coulissants agencés de manière telle que le panneau avant est mobile entre une position fermée dans laquelle il recouvre l'habitacle et une position ouverte dans laquelle il est, après coulissement vers l'arrière, superposé au panneau central. Le système de toit précité comporte deux glissières parallèles de formes arquées fixées à la carrosserie du véhicule et s'étendent chacune entre point proche de l'avant du panneau central et un point proche du fond du coffre arrière du véhicule et de la partie arrière du véhicule, le panneau central comportant des organes coopérants avec les glissières pour guider son déplacement le long de celle-ci. Un inconvénient à cette solution, comme à d'autres connues pour ranger des toits ouvrants concerne le volume que prend le toit replié sur l'espace réservé au rangement (bagages...)? à l'arrière de l'habitacle, typiquement dans le coffre arrière (que ce coffre soit saillant ou non) . La présente invention a pour but de remédier aux inconvénients du système précité et de proposer une solution peu encombrante, adaptable à différents types de véhicules et réalisable en grandes séries. La solution proposée vise un véhicule avec un toit ouvrant en au moins deux parties mobiles pouvant être rangées en position finale a priori sensiblement à l'horizontale et une lunette arrière basculante (en particulier oscillo-coulissante) appartenant ou non auxdites parties mobiles de toit précitées, ladite position de rangement laissant un volume de rangement important. Plus précisément, suivant la présente invention, le véhicule concerné présente un avant et un arrière et comprend : un habitacle avec des sièges situés vers l'arrière de l'habitacle, - une structure de véhicule définissant localement un pavillon qui présente une ouverture obturable et un toit rétractable, ce toit comprenant au moins deux parties rigides et mobiles par rapport à ladite structure, respectivement une première partie avant et une seconde partie arrière, - des premiers éléments de déplacement auxquels sont liés lesdites parties de toit pendant une partie au moins de leur mouvement, entre une position déployée, atteinte par déplacement vers l'avant et dans laquelle ces parties recouvrent l'habitacle, sensiblement alignées l'une derrière l'autre, et une position repliée atteinte par déplacement vers l'arrière du véhicule et dans laquelle lesdites parties sont décalées l'une par rapport à l'autre et derrière les sièges, certaines au moins de ces parties de toit étant alors disposées dans une première position de rangement, le véhicule se caractérisant en ce qu'il comprend en outre des seconds éléments de déplacement qu' engagent au moins celles desdites parties de toit alors qu'elles sont disposées dans leur dite première position de rangement , pour déplacer si nécessaire ces parties de toit vers une seconde position de rangement différente de la première (et a priori sensiblement horizontale) . Un tel système de toit améliore l'espace de rangement disponible à l'arrière dans le coffre. Par souci de compacité, efficacité et fiabilité, les seconds moyens de déplacement seront de préférence montés mobiles par rapport à la structure du véhicule et par rapport aux premiers moyens de déplacement, les parties de toit disposées en première position de rangement se dégageant des premiers moyens de déplacement tout en engageant les seconds moyens de déplacement pour être deplaçables de leur première position vers leur seconde position de rangement. Par ailleurs, on conseille que: les premiers et les seconds moyens de déplacement comprennent respectivement des premières et des secondes glissières, - lesdites parties rigides de la première partie de toit comprennent plusieurs panneaux, sensiblement plats, mobiles les uns par rapport aux autres et disposés, en position fermée du toit, au-dessus de l'habitacle, devant un élément arrière de toit comprenant la lunette arrière du véhicule et' appartenant à ladite seconde partie de toit, - et, pour se replier, lesdits panneaux mobiles de toit passent successivement en première puis en seconde position de rangement, en engageant successivement les premières glissières puis les secondes glissières, lesquelles sont montées sur la structure, mobiles par rapport aux premières glissières pour faire ainsi' se déplacer les panneaux de toit entre leurs dites première et seconde positions de rangement. Il s'agit là d'une mécanique fiable et peu encombrante. De préférence, chaque ensemble de glissières et les seconds éléments de déplacement qui lui est lié définissent en outre une première partie avant de glissière s ' étendant entre un point situé à l'avant de ladite partie arrière de toit et un point proche du bord supérieur de l'arrière desdits sièges, et une seconde partie de glissière s 'étendant, en position inclinée, entre sensiblement ledit bord supérieur de l'arrière desdits sièges et un point situé plus bas, chaque deuxième partie de glissière étant montée mobile par rapport à la structure du véhicule et à la première partie de glissière correspondante et étant liée aux dites parties de toit concernées, lorsqu'elles arrivent dans leur première position repliée et que ces parties sont alors engagées avec les deuxième parties de glissières et dégagées des premières parties de glissières, pour amener ces parties de toit dans leur dite seconde position superposée de rangement. Là encore, on doit atteindre dans le véhicule une compacité et une bonne efficacité et fiabilité de fonctionnement . En outre, un tel système rétractable permet un guidage précis des parties de toit entre leur position de fermeture au-dessus de l'habitacle et leur position d'ouverture (rangée à l'arrière). Selon une autre caractéristique, l'invention prévoit que : - lesdites parties de toit comprennent au moins deux dits panneaux rigides, respectivement un premier panneau avant et un second panneau central, les panneaux étant liés ensemble par des moyens de liaison agencés de telle manière que le panneau avant est mobile entre sa position dépliée, atteinte par déplacement vers l'avant et dans laquelle ledit panneau est au-dessus de l'habitacle, devant le panneau central, et une position ouverte atteinte par déplacement vers l'arrière du véhicule et dans laquelle les panneaux avant et central sont superposés sensiblement horizontalement, ce dernier étant déplaçable, par coopération avec les premiers moyens de déplacement et en même temps que le panneau avant qui le jouxte, entre sa position déployée dans laquelle il est au-dessus de l'habitacle et sa première position de rangement (repliée) dans laquelle les panneaux avant et central sont escamotés, côte à côte, dans l'espace de rangement, en position déployée des parties de toit, celles-ci sont interposées, l'une derrière l'autre, entre, à l'avant, le pare-brise qui est fixe sur la structure du véhicule, et un élément arrière (qui peut être escamotable) comprenant la lunette arrière, et, en seconde position rangée (illustrée horizontalement) , les panneaux avant et central sont de préférence soit disposés en partie supérieure de ladite zone de rangement du toit, soit en partie inférieure, dans un dégagement de fond de l'espace de rangement. Dans le cas où on envisage une lunette arrière escamotable, l'invention prévoit avantageusement que l'élément arrière de toit soit déplaçable entre sa position déployée dans laquelle il est au-dessus de l'habitacle et sa position repliée dans laquelle il est basculé vers l'arrière directement sensiblement à l'horizontale, en partie supérieure de l'espace de rangement, derrière les sièges et au-dessus du niveau de rangement des autres panneaux avant. Selon un autre aspect, l'invention prévoit, pour ranger le toit ouvrant dans son espace de rangement derrière les sièges arrière: - a) partant d'un état fermé du toit dans lequel les deux parties de toit recouvrent l'habitacle, en étant sensiblement alignées l'une derrière l'autre, de déplacer ces parties de toit jusqu'à l'intérieur de l'espace de rangement, certaines au moins de ces parties étant amenée jusqu'à une première position de rangement sensiblement verticale, b) puis de déplacer à nouveau la (les) partie (s) ' de toit concernée (s) vers une position sensiblement horizontale, pour dégager horizontalement une profondeur utile. On décrira maintenant, à titre non limitatif, des réalisations particulières de l'invention, en référence aux dessins schématiques annexés dans lesquels: - la figure 1 est une vue schématique d'un véhicule équipé d'un système de toit rétractable utilisable ici, - la figure 2 est une vue de côté d'une partie d'un véhicule muni d'un toit coulissant/basculant, - les figures 3 et 4 montrent deux réalisations possibles de systèmes de toit ouvrant conformes àRetractable sunroof vehicle and method of storing such a roof, with a horizontal tilting system. The present invention relates to a retractable roof system for a fixed or mobile structure, in particular for a motor vehicle. There is known from FR 2 798 327 a retractable roof system for a vehicle consisting of at least two rigid roof panels, respectively a first element of the front and a second central roof element secured to one another by sliding means arranged in such a way that the front panel is movable between a closed position in which it covers the passenger compartment and an open position in which it is, after sliding towards the rear, superimposed on the central panel. The aforementioned roof system comprises two parallel slides of arcuate shapes fixed to the vehicle body and each extend between a point close to the front of the central panel and a point close to the bottom of the rear boot of the vehicle and the rear part of the vehicle, the central panel comprising members cooperating with the slides to guide its movement along the latter. A drawback to this solution, as to others known for storing sunroofs, concerns the volume that the folded roof takes up on the space reserved for storage (luggage ...) ? at the rear of the passenger compartment, typically in the rear trunk (whether this trunk is protruding or not). The present invention aims to remedy the drawbacks of the above system and to provide a space-saving solution, adaptable to different types of vehicles and achievable in large series. The proposed solution is aimed at a vehicle with a sunroof in at least two movable parts which can be stored in the final position a priori substantially horizontally and a tilting rear window (in particular tilt-and-slide) belonging or not to said aforementioned movable parts of roof , said storage position leaving a large storage volume. More specifically, according to the present invention, the vehicle concerned has a front and a rear and comprises: a passenger compartment with seats situated towards the rear of the passenger compartment, - a vehicle structure locally defining a roof which has a closable opening and a retractable roof, this roof comprising at least two rigid and movable parts relative to said structure, respectively a first front part and a second rear part, - first displacement elements to which said roof parts are connected during at least one part their movement, between a deployed position, reached by moving forward and in which these parts cover the passenger compartment, substantially aligned one behind the other, and a folded position reached by moving towards the rear of the vehicle and in which said parts are offset from each other and behind the seats, at least some of these roof parts then being arranged in a first storage position, the vehicle being characterized in that it further comprises second displacement elements which engage at least those of said roof parts while they are arranged in their said first position of storage, to move these roof parts if necessary to a second storage position different from the first (and a priori substantially horizontal). Such a roof system improves the storage space available at the rear in the trunk. For the sake of compactness, efficiency and reliability, the second displacement means will preferably be mounted movable relative to the structure of the vehicle and relative to the first displacement means, the roof parts arranged in the first storage position emerging from the first means movement while engaging the second displacement means to be movable from their first position to their second storage position. Furthermore, it is advised that: the first and second displacement means respectively comprise first and second slides, - said rigid parts of the first roof part comprise several panels, substantially flat, movable with respect to each other and arranged , in the closed position of the roof, above the passenger compartment, in front of a rear roof element comprising the rear window of the vehicle and 'belonging to said second roof part, - and, for folding, said movable roof panels pass successively in first then in second storage position, successively engaging the first slides then the second slides, which are mounted on the structure, movable relative to the first slides to thus make ' move the roof panels between their said first and second storage positions. This is a reliable and space-saving mechanism. Preferably, each set of runners and the second displacement elements which are linked to it further define a first front part of runner extending between a point situated in front of said rear roof part and a point close to the upper edge. from the rear of said seats, and a second part of slide extending, in an inclined position, between substantially said upper edge of the rear of said seats and a point located lower, each second part of slide being mounted movable relative to the structure of the vehicle and to the corresponding first slide part and being linked to the said roof parts concerned, when they arrive in their first folded position and these parts are then engaged with the second slide parts and released from the first parts of slides, to bring these roof parts into their said second superposed storage position. Here again, compactness and good operating efficiency and reliability must be achieved in the vehicle. In addition, such a retractable system allows precise guidance of the roof parts between their closed position above the passenger compartment and their open position (rear row). According to another characteristic, the invention provides that: - said roof parts comprise at least two said rigid panels, respectively a first front panel and a second central panel, the panels being linked together by connecting means arranged in such a way that the front panel is movable between its unfolded position, reached by moving forwards and in which said panel is above the passenger compartment, in front of the central panel, and an open position reached by moving towards the rear of the vehicle and in which the front and central panels are superimposed substantially horizontally, the latter being movable, by cooperation with the first displacement means and at the same time as the front panel which adjoins it, between its deployed position in which it is above the passenger compartment and its first position of storage (folded) in which the front and central panels are retracted, side by side, in the storage space, in the deployed position of the roof parts, these are interposed, one behind the other, between, at the front, the windshield which is fixed to the structure of the vehicle, and a rear element (which can be retractable) comprising the rear window, and, in the second row position (illustrated ho horizontally), the front and central panels are preferably either arranged in the upper part of said roof storage area, or in the lower part, in a bottom clearance of the storage space. In the case where a retractable rear window is envisaged, the invention advantageously provides that the rear roof element is movable between its deployed position in which it is above the passenger compartment and its folded position in which it is tilted towards the rear directly substantially horizontal, in the upper part of the storage space, behind the seats and above the storage level of the other front panels. According to another aspect, the invention provides, for storing the sunroof in its storage space behind the rear seats: - a) starting from a closed state of the roof in which the two roof parts cover the passenger compartment, while being substantially aligned one behind the other, to move these roof parts to the interior of the storage space, at least some of these parts being brought to a first substantially vertical storage position, b) then again moving the part (s) ' of roof concerned (s) to a substantially horizontal position , to release a useful depth horizontally.

Dans la réalisation représentée, l'invention comporte trois éléments (ou parties) de toit centraux 1,3,5 montés coulissants sur deux glissières latérales parallèles 7 s' étendant notamment de chaque côté d'une ouverture 10 ménagée dans le pavillon 14. Sont également prévus un élément (ou partie) de toit arrière (lunette) 9 monté oscillo-coulissant par un bras 11 relié au châssis 13 (appelé également structure du véhicule 15) et une glissière 17 montée pivotante sur ladite structure 13, suivant un axe 17a transversal à la direction longitudinale 19 d'avance du véhicule. La glissière 17 bascule ainsi avec le capot de coffre 59 lorsqu'il s'articule par rapport à la structure du véhicule pour s'ouvrir (uniquement) de l'arrière vers 1' avant . Dans la description, on appellera "éléments de toit centraux", les éléments de toit montés sur la glissière 7 et "élément de toit arrière" la partie arrière basculante 9 qui comprend la lunette arrière 90. Ainsi, les éléments de toit centraux 1,3,5 sont, en position fermée du toit au-dessus de l'habitacle, interposés entre le pare-brise 150 fixé à la structure 13 et l'élément arrière 9 (qui peut être fixe ou mobile) . Les glissières 7 sont de forme arquée et s'étendent entre une zone 7a située (dans l'exemple de la figure 1) à l'avant de l'élément de toit 1 , de part et d'autre de l'ouverture 10, et une zone 7b située dans l' espace 53 de rangement du toit en position repliée, derrière les sièges 55, en partie haute de leurs dossiers, sous le niveau d'articulation en 17a des glissières additionnelles 17. Dans une autre réalisation, les glissières 7 pourraient s'interrompre, à l'avant, en regard de l'élément de toit 5 situé juste devant l'élément le plus arrière 9, en particulier dans l'hypothèse d'un toit ouvrant en deux parties uniquement : 5 et 9. Pour être replié dans l'espace de rangement 53, le panneau central 5 est déplaçable en entraînant les panneaux 1, 3 qui lui sont alors superposés, entre une position fermée, dans laquelle il recouvre l'habitacle, et une position repliée dans laquelle les trois panneaux 1,3,5 sont logés, dans leur position côte à côte, dans une première position de rangement inclinée par rapport à l'horizontale, derrière l'habitacle 57. Le système qui permet de guider le déplacement des panneaux 1,3 vers leur position superposée avec le panneau 5, en haut du toit, ne sera pas décrit en détail ici. En effet, il a été décrit dans le brevet français FR-B-2694245 et dans la demande de brevet français FR-A- 2 797 226. Le panneau central 5 comporte des organes qui seront détaillés plus loin et qui coopèrent avec les deux glissières 7 pour guider son déplacement le long de celles-ci . Comme on le voit notamment sur la figure 2, la forme arquée des glissières 7 présente une concavité dirigée vers l'intérieur de l'habitacle. Cette forme arquée permet de guider le déplacement des panneaux 1,3,5 par un passage compris entre les sièges arrière 55 et la partie arrière 9 du toit. Les organes du panneau 5 coopérant avec les glissières comprennent deux galets 37,39 fixés à des pattes 37a, 39a situées près de chacun des bords latéraux 5a du panneau 5, respectivement près de l'avant et près de l'arrière de ce dernier, comme indiqué sur la figure 2. Le système de toit rétractable selon l'invention, comporte en outre des moyens pour entraîner le déplacement du panneau 5 le long des glissières. Ces moyens peuvent comprendre des câbles entraînés par un moteur ou un vérin. De préférence, les galets 37,39 sont conformés en pignons (voir figures 6,7 et engrenés dans une crémaillère 70 solidaire de chaque glissière 7 (ou 51 comme on le comprendra ci-après) et suivant le profil de celle-ci. Comme on le voit sur les figures 2 et 6, la paire de galets 39, située près de l'arrière du panneau 5, est entraînée en rotation par un moteur électrique 72 relié à chaque galet par un demi-arbre de transmission 74. La figure 5 montre, d'autre part, que chaque glissière 7 est fixée à sa partie supérieure l'une des deux parties latérales 8 du toit fixe, situées de part et d'autre de l'ouverture 10 du toit. Une fois les éléments de toit centraux 1,3,5 superposés sensiblement horizontalement les uns sur les autres (fig 3 et 4) l'élément de toit arrière 9 est entraîné par le bras 11 vers l'arrière permettant ainsi de décaler vers le haut le bord avant 9a de l'élément de toit arrière 9 et permettant ainsi le passage des éléments de toit centraux. La rétractation de ces éléments de toit centraux fonctionne de la façon suivante: Dans une première étape, un mécanisme approprié, commande le coulissement panneau avant 1 vers l'arrière, jusqu'à ce que ce panneau se superpose au panneau 3, puis que ces deux panneaux se superposent ensemble sur le panneau 5, comme montré figures 1 et 2. A partir de cette position où les panneaux 1,3,5 sont verrouillés ensemble, on commande la mise en route du moteur électrique 72. Celui-ci entraîne en rotation les demi-arbres 74 et les galets 39 en forme pignon. La rotation de ces galets 39 avec les crémaillères 40 des glissières 7 déplace les panneaux vers l'espace 53, derrière les sièges 55, jusqu'à ce que les galets arrivent en fin de course. Suivant la courbure des glissières, les deux panneaux 1,3,5 occupent préférentiellement, dans cette première position de rangement, une position presque verticale (figure 3) ou inclinée par rapport à l'horizontale (figure 4). Bien entendu, une commande de rotation du moteur électrique en sens inverse, provoque alors un déplacement des panneaux 1,3,5 depuis le coffre vers la position de fermeture du toit. Dans la continuité de chaque glissière 7 se trouve une glissière mobile 51 que vont engager les panneaux 1,3,5 alors qu'ils se désengagent de la glissière 7, pour accéder à leur seconde position de rangement. Ainsi, on va pouvoir sélectivement escamoter ces panneaux dans une position de rangement a priori la moins gênante possible, soit juste sous l'élément arrière 9, en partie haute de l'espace 53 (figs. 3 et 4), soit en fond de coffre (fig. 3) . C'est orientée sensiblement horizontalement que cette position définitive de rangement est apparue comme la plus appropriée, en ce qu'ainsi, on dégage l'espace 53 à l'avant jusqu'aux sièges 55, voire au-delà si on les rabat vers l'avant. Pour atteindre leur seconde position de rangement, les éléments de toit centraux sont, dans la réalisation de la figure 3, et au delà de la glissière 7, entraînés le long de la glissière pivotante 51 dans une position sensiblement verticale dans le coffre ou espace de rangement 53 situé derrière les sièges 55 du véhicule les plus en arrière de l'habitacle 57. La glissière mobile 51 s'étend le long des dossiers de siège 55, dans cette première position de rangement vertical des éléments de toit 1,3,5. Une fois ces éléments de toit centraux rangés verticalement, l'élément de toit arrière 9 va basculer vers l'arrière depuis sa position haute au-dessus de l'arrière de l'habitacle vers sa position rangée dans l'espace 53, par l'intermédiaire du bras d'entraînement 11, guidé par la glissière 17 pour venir se positionner directement et a priori définitivement en position sensiblement horizontale (repère 9 en pointillés sur la fig 1) . Les éléments de toit centraux 1,3,5 sont alors toujours dans leur position sensiblement verticale sur la deuxième glissière 51 montée pivotante sur la structure 13. Cette deuxième glissière va faire pivoter les éléments de toit centraux de leur première position rangée sensiblement verticalement vers une position de rangement sensiblement horizontale qui peut être située dans un dégagement de fond 61 du plancher 63 du coffre, en regard de l'espace de rangement 53 (position dite sensiblement horizontale basse correspondant au repère A sur la fig 1) . La deuxième glissière 51 est articulée dans ce cas à la structure 13 par un axe de rotation 65 transversal à l'axe 19 longitudinal de véhicule situé sur l'extrémité inférieure 51a de la deuxième glissière pivotante. Dans cette version, il est également possible de faire pivoter les éléments de toit 1,3,5 rangés dans leur position sensiblement verticale, vers une position de rangement sensiblement horizontale sous la lunette arrière 9 en position de rangement sensiblement horizontale (dite alors position sensiblement horizontale haute correspondant au repère B de la fig 1) . La glissière 51 est alors articulée au châssis 13 par un axe de rotation 67 transversal à l'axe longitudinal 19 situé sur l'extrémité supérieure 51b de cette glissière. Par un système de verrous non représentés, il pourrait même être possible de faire pivoter les éléments de toit entre leurs dites positions de rangement sensiblement verticale et horizontale, haute ou basse, en prévoyant sur la glissière 51 les deux axes de pivotement 65,67, et en agissant sélectivement sur l'un ou l'autre des verrous. Des moyens sélectifs, tels qu'un interrupteur 200 lié à un câble 201 et à un moteur 203 lui-même relié à la partie de glissière 51 concernée, permettent de commander à volonté le mouvement des parties concernées de toit entre leurs première et seconde positions de rangement (ici respectivement verticale et horizontale) . Il est possible également de faire basculer le dossier de sièges arrière 55 vers l'avant dans une position sensiblement horizontale (voir repère 55 en pointillés sur la fig 1) permettant ainsi d'augmenter encore le volume de coffre. On pourrait même envisager la solution d'une deuxième glissière telle que 51 solidaire du dossier de siège pivotant vers l'avant et positionnant ainsi les éléments de toit rangés dans une position sensiblement horizontale au-dessus du dossier de siège. Dans la version de la figure 4, le second ensemble de glissière mobile qui permet de faire passer les panneaux de toit 1, 3, 5 de leur première position de rangement à leur seconde position de rangement a été repéré 80. Cette ensemble de glissières 80 (une glissière dans la continuité de chaque première glissière 7) est articulé sensiblement à mi-longueur, autour d'un axe 81, perpendiculaire à l'axe longitudinal 19 du véhicule. Chaque glissière 80 est manœuvrée par un système motorisé comprenant en l'espèce un vérin 83. Sur la figure 4, la courbure de la glissière 7 est moindre et son extrémité arrière s'interrompt en 7b à l'arrière de l'habitacle, mais juste au dessus du dossier arrière des sièges arrières 55. Les glissières 80 s'étendent dans la continuité axiale, au-dessus de l'espace de rangement 53, c'est-à-dire en partie haute du coffre dont on n'a une nouvelle fois repéré en 59 le capot, lequel est articulé uniquement à l'avant en 59a, pour s'ouvrir exclusivement vers l'avant du véhicule, dans le sens de la flèche 85. Chaque glissière 80 est rectiligne et s'étend derrière le dossier des sièges 55, sur une partie substantielle (l'essentiel) de la profondeur P du coffre, lequel se confond donc ici avec l'espace de rangement 53. L'axe de pivotement 81 des secondes glissières 80 est situé sensiblement au niveau du sommet des sièges 55, ou bien légèrement au-dessous. On n'aura noté que, dans la solution de la figure 4, les panneaux de toit 1, 3, 5 ne sont pas strictement verticaux dans leur première position de rangement (trait plein sur la figure) , mais toutefois inclinés par rapport à l'horizontale, en partie basse de l'élément arrière 9, de sorte qu'ils occultent une partie au moins de la rétro vision à travers la lunette arrière 90. C'est pour rétablir une vision favorable vers l'arrière, améliorer l'esthétique, sans toutefois occuper exagérément du volume dans l'espace de rangement 53, que l'on prévoit une possible mobilité (en l'espèce basculement) de ces panneaux 1, 3, 5 de leur première position de rangement superposée vers leur position définitive de rangement ou ils sont donc toujours superposés avec la même superposition, mais en position alors sensiblement horizontale, comme montré en pointillé en regard de la zone C de la figure 4. Une fois parvenue dans cette position, atteinte suite à 1 ' actionnement du vérin 83 et au dégagement des galets 37, 39 vis-à-vis des glissières 7 suivi d'un engagement dans les glissières 80, l'élément arrière de toit 9 finit le basculement arrière qu'il avait commencé pour laisser le passage aux panneaux de toit, l'élément 9, mû toujours par ses bras latéraux 11 et le guidage des glissières 17 se plaçant toujours dans la même position que celle de la figure 3, ici juste au-dessus des panneaux 1, 3, 5, dans un mouvement oscillo- coulissant . La commande motorisé de l'élément arrière 9 pouvant être traditionnelle, elle n'a été ni décrite ni représentée . Dans ce qui précède, on n'aura noté que c'est le panneau arrière 5 des panneaux de toit 1, 3, 5 qui entraîne le mouvement des panneaux entre les positions représentées sur les figures 3 et 4. On peut toutefois prévoir que ce soit le panneau avant 1 qui soit moteur, étant par exemple pour cela relié à un système de motorisation qui, par l'intermédiaire de câbles d'entraînement, provoquerait le déplacement des panneaux entre leurs positions extrêmes fermée et ouverte. In the embodiment shown, the invention comprises three central roof elements (or parts) 1,3,5 slidably mounted on two parallel side rails 7 extending in particular on each side of an opening 10 formed in the pavilion 14. Are also provided a rear roof element (or part) (window) 9 mounted tilt-and-slide by an arm 11 connected to the chassis 13 (also called vehicle structure 15) and a slide 17 pivotally mounted on said structure 13, along an axis 17a transverse to the longitudinal direction 19 of advance of the vehicle. The slide 17 thus switches with the boot lid 59 when it is articulated relative to the structure of the vehicle to open (only) from the rear towards the front. In the description, the term “central roof elements” will mean the roof elements mounted on the slide 7 and “rear roof element” the tilting rear part 9 which includes the rear window 90. Thus, the central roof elements 1, 3.5 are, in the closed position of the roof above the passenger compartment, interposed between the windshield 150 fixed to the structure 13 and the rear element 9 (which can be fixed or mobile). The slides 7 are of arcuate shape and extend between a zone 7a situated (in the example of FIG. 1) at the front of the roof element 1, on either side of the opening 10, and a zone 7b located in the space 53 for storing the roof in the folded position, behind the seats 55, in the upper part of their backrests, under the level of articulation in 17a of the additional slides 17. In another embodiment, the slides 7 could be interrupted, at the front, facing the roof element 5 situated just in front of the rearmost element 9, in particular in the case of a sunroof opening in two parts only: 5 and 9 To be folded into the storage space 53, the central panel 5 can be moved by driving the panels 1, 3 which are then superimposed on it, between a closed position, in which it covers the passenger compartment, and a folded position in which the three panels 1, 3, 5 are housed, in their position side by side, in a first storage position inclined relative to the horizontal, behind the passenger compartment 57. The system which makes it possible to guide the movement of the panels 1,3 towards their superimposed position with the panel 5, at the top of the roof, will not be described in detail here. Indeed, it has been described in French patent FR-B-2694245 and in French patent application FR-A- 2 797 226. The central panel 5 comprises members which will be detailed below and which cooperate with the two slides 7 to guide its movement along them. As seen in particular in Figure 2, the arcuate shape of the slides 7 has a concavity directed towards the interior of the passenger compartment. This arcuate shape makes it possible to guide the movement of the panels 1,3,5 by a passage comprised between the rear seats 55 and the rear part 9 of the roof. The members of the panel 5 cooperating with the slides comprise two rollers 37, 39 fixed to lugs 37a, 39a situated near each of the lateral edges 5a of the panel 5, respectively near the front and near the rear of the latter, as shown in Figure 2. The retractable roof system according to the invention further comprises means for causing the displacement of the panel 5 along the rails. These means may include cables driven by a motor or a jack. Preferably, the rollers 37,39 are shaped into pinions (see Figures 6,7 and meshed in a rack 70 integral with each slide 7 (or 51 as will be understood below) and according to the profile thereof. As seen in Figures 2 and 6, the pair of rollers 39, located near the rear of the panel 5, is rotated by an electric motor 72 connected to each roller by a half-shaft transmission 74. The Figure 5 shows, on the other hand, that each slide 7 is fixed at its upper part one of the two side parts 8 of the fixed roof, located on either side of the opening 10 of the roof. Once the central roof elements 1,3,5 superimposed substantially horizontally on each other (fig 3 and 4) the rear roof element 9 is driven by the arm 11 towards the rear thus making it possible to shift upwards the front edge 9a of the rear roof element 9 and thus allowing the passage of the central roof elements. The retraction of these central roof elements works in the following way: In a first step, an appropriate mechanism controls the sliding of the front panel 1 backwards, until this panel is superimposed on the panel 3, then these two panels are superimposed together on the panel 5, as shown in FIGS. 1 and 2. From this position where the panels 1, 3, 5 are locked together, the electric motor 72 is started up. rotation the half-shafts 74 and the rollers 39 in pinion shape. The rotation of these rollers 39 with the racks 40 of the slides 7 moves the panels towards the space 53, behind the seats 55, until the rollers arrive at the end of the race. According to the curvature of the slides, the two panels 1, 3, 5 preferably occupy, in this first storage position, an almost vertical position (FIG. 3) or inclined relative to the horizontal (FIG. 4). Of course, a rotation control of the electric motor in the opposite direction, then causes displacement of the panels 1, 3, 5 from the boot to the closed position of the roof. In the continuity of each slide 7 is a movable slide 51 that the panels 1, 3, 5 will engage while they disengage from the slide 7, to access their second storage position. Thus, we will be able to selectively retract these panels in a storage position a priori the least troublesome possible, either just under the rear element 9, in the upper part of the space 53 (figs. 3 and 4), or at the bottom of trunk (fig. 3). It is oriented substantially horizontally that this final storage position appeared to be the most suitable, in that way, the space 53 is released at the front to the seats 55, or even beyond if it is folded towards forward. To reach their second storage position, the central roof elements are, in the embodiment of FIG. 3, and beyond the slide 7, driven along the pivoting slide 51 in a substantially vertical position in the trunk or space of storage 53 located behind the seats 55 of the vehicle furthest back from the passenger compartment 57. The movable slide 51 extends along the seat backs 55, in this first position for vertical storage of the roof elements 1,3,5 . Once these central roof elements are stored vertically, the rear roof element 9 will tilt backwards from its high position above the rear of the passenger compartment to its position stored in space 53, by means of the drive arm 11, guided by the slide 17 to come position themselves directly and a priori definitively in a substantially horizontal position (point 9 in dotted lines in FIG 1). The central roof elements 1, 3, 5 are then always in their substantially vertical position on the second slide 51 pivotally mounted on the structure 13. This second slide will rotate the central roof elements from their first position stored substantially vertically towards a substantially horizontal storage position which can be located in a bottom clearance 61 of the floor 63 of the trunk, opposite the storage space 53 (so-called substantially horizontal low position corresponding to the reference A in FIG 1). The second slide 51 is articulated in this case to the structure 13 by an axis of rotation 65 transverse to the longitudinal axis 19 of the vehicle located on the lower end 51a of the second pivoting slide. In this version, it is also possible to rotate the roof elements 1,3,5 stored in their substantially vertical position, towards a substantially horizontal storage position under the rear window 9 in substantially horizontal storage position (then called substantially position horizontal high corresponding to the mark B in fig 1). The slide 51 is then articulated to the chassis 13 by an axis of rotation 67 transverse to the longitudinal axis 19 located on the upper end 51b of this slide. By a system of locks not shown, it might even be possible to pivot the roof elements between their said substantially vertical and horizontal storage positions, high or low, by providing on the slide 51 the two pivot axes 65,67, and by acting selectively on one or the other of the locks. Selective means, such as a switch 200 linked to a cable 201 and to a motor 203 itself connected to the slide part 51 concerned, make it possible to control at will the movement of the concerned parts of the roof between their first and second positions storage (here respectively vertical and horizontal). It is also possible to tilt the rear seat backrest 55 forwards into a substantially horizontal position (see item 55 with dotted lines in FIG. 1), thus making it possible to further increase the volume of the boot. We could even consider the solution of a second slide such as 51 secured to the seat back pivoting forwards and thus positioning the roof elements stored in a substantially horizontal position above the seat back. In the version of FIG. 4, the second movable slide assembly which allows the roof panels 1, 3, 5 to pass from their first storage position to their second storage position has been marked 80. This set of slides 80 (a slide in the continuity of each first slide 7) is articulated substantially at mid-length, around an axis 81, perpendicular to the longitudinal axis 19 of the vehicle. Each slide 80 is operated by a motorized system comprising in this case a jack 83. In FIG. 4, the curvature of the slide 7 is less and its rear end is interrupted at 7 b at the rear of the passenger compartment, but just above the rear backrest of the rear seats 55. The slides 80 extend in the axial continuity, above the storage space 53, that is to say in the upper part of the boot, the cover of which has again been identified at 59, which is articulated only at the front in 59a, to open exclusively towards the front of the vehicle, in the direction of arrow 85. Each slide 80 is rectilinear and extends behind the seat back 55, over a substantial part (essentially) of the depth P of the trunk, which therefore merges here with the storage space 53. The pivot axis 81 of the second runners 80 is located substantially at the top of the seats 55, or slightly below. It will have been noted that, in the solution of FIG. 4, the roof panels 1, 3, 5 are not strictly vertical in their first storage position (solid line in the figure), but nevertheless inclined relative to the 'horizontal, in the lower part of the rear element 9, so that they obscure at least part of the retro vision through the rear window 90. This is to restore favorable vision towards the rear, improve the aesthetic, without however occupying excessively the volume in the storage space 53, that provision is made for possible mobility (in this case tilting) of these panels 1, 3, 5 from their first storage position superimposed towards their final position or they are therefore always superimposed with the same superimposition, but in position then substantially horizontal, as shown in dotted lines opposite zone C of FIG. 4. Once in this position, reached following actuation of the jack 83 and disengagement of the rollers 37, 39 with respect to the slides 7 followed by an engagement in the slides 80, the rear roof element 9 finishes the rear tilting which it had started to allow passage to the roof panels, the element 9, still moved by its lateral arms 11 and the guide of the slides 17 always being placed in the same position as that of FIG. 3, here just above the panels 1, 3, 5, in an oscillating-sliding movement. The motorized control of the rear element 9 can be traditional, it has neither been described nor shown. In the foregoing, it will have been noted that it is the rear panel 5 of the roof panels 1, 3, 5 which causes the movement of the panels between the positions represented in FIGS. 3 and 4. It can however be provided that this or the front panel 1 which is motor, being for example connected to a motorization system which, by means of drive cables, would cause the displacement of the panels between their extreme closed and open positions.
