Description

VEHICULE AUTOMOBILE COMPORTANT UN TOIT ESCAMOTABLE EN MATIERE SOUPLE EQUIPE D'UNE LUNETTE ARRIERE  MOTOR VEHICLE HAVING A FLEXIBLE ROOF IN SOFT MATERIAL EQUIPPED WITH A REAR WINDOW
La présente invention concerne un véhicule automobile comportant un toit en matière souple équipé d'une lunette arrière. The present invention relates to a motor vehicle having a roof made of flexible material equipped with a rear window.
On connaît par exemple selon le document US 6 199 936 un véhicule automobile comportant un toit escamotable en matière souple équipé d'une lunette arrière, ce toit escamotable étant déplaçable grâce à un mécanisme d'entraînement du toit, entre une position fermée dans laquelle le toit recouvre l'habitacle du véhicule et une position ouverte dans laquelle le toit est replié dans un logement situé derrière l'habitacle.  For example, according to document US Pat. No. 6,199,936, a motor vehicle is known comprising a retractable roof made of flexible material equipped with a rear window, this retractable roof being movable thanks to a mechanism for driving the roof, between a closed position in which the roof covers the passenger compartment of the vehicle and an open position in which the roof is folded into a housing located behind the cockpit.
Le mécanisme d'entraînement du toit souple comprend des bras pivotants articulés au toit souple et à la caisse du véhicule.  The flexible roof drive mechanism includes articulated pivot arms with a flexible roof and vehicle body.
Le pivotement des bras vers l'arrière permet de replier la matière souple du toit et la lunette arrière dans un logement situé à l'arrière du véhicule.  Pivoting the arms to the rear folds the soft roof material and the rear window into a seat at the rear of the vehicle.
Selon ce document, la lunette arrière est entièrement libre par rapport au mécanisme d'entraînement du toit et ce document ne divulgue pas de moyens permettant de stabiliser la position de la lunette arrière lorsque le toit est fermé et lorsque le toit est ouvert.  According to this document, the rear window is completely free from the roof drive mechanism and this document does not disclose means for stabilizing the position of the rear window when the roof is closed and when the roof is open.
Le but de la présente invention est précisément de créer de tels moyens. The object of the present invention is precisely to create such means.
Ce but est atteint, selon l'invention, grâce à un véhicule automobile comportant un toit escamotable en matière souple équipé d'une lunette arrière, ce toit escamotable étant déplaçable grâce à un mécanisme d'entraînement du toit, entre une position fermée dans laquelle le toit recouvre l'habitacle du véhicule et une position ouverte dans laquelle le toit est replié dans un logement situé derrière l'habitacle, caractérisé en ce que ledit mécanisme est directement relié à la lunette arrière par une liaison mécanique rigide permettant de faire pivoter la lunette arrière de l'arrière vers l'avant lors du déplacement du toit entre la position fermée et la position ouverte. This object is achieved, according to the invention, thanks to a motor vehicle having a retractable roof made of flexible material equipped with a rear window, this retractable roof being movable thanks to a roof drive mechanism, between a closed position in which the roof covers the passenger compartment of the vehicle and an open position in which the roof is folded into a housing located behind the passenger compartment, characterized in that said mechanism is directly connected to the rear window by a rigid mechanical connection to rotate the rear window from the rear to the front when moving the roof between the closed position and the open position.
Ainsi, lorsque le mécanisme d'entraînement du toit déplace ce toit vers le logement arrière du véhicule, ce mécanisme commande simultanément grâce à la liaison mécanique rigide le pivotement de la lunette arrière de l'arrière vers l'avant, de façon que la matière souple du toit puisse se replier sur cette lunette arrière. Par ailleurs, cette liaison rigide entre le mécanisme d'entraînement du toit et la lunette arrière stabilise la lunette arrière dans les deux positions et ce, sans qu'il soit nécessaire de prévoir d'autres organes mécaniques complexes et coûteux. Thus, when the roof drive mechanism moves this roof toward the rear housing of the vehicle, this mechanism controls simultaneously through the rigid mechanical connection the pivoting of the rear window from rear to front, so that the material flexible roof can be folded on this rear window. Furthermore, this rigid connection between the roof drive mechanism and the rear window stabilizes the rear window in both positions and without the need to provide other complex and expensive mechanical organs.
Dans une version préférée de l'invention, la lunette arrière est montée pivotante autour d'un axe fixe et transversal par rapport à l'axe longitudinal du véhicule et situé près du bord inférieur de la lunette arrière, ladite liaison mécanique étant constituée par une bielle articulée à une manivelle reliée à la lunette arrière, l'articulation de la bielle à la manivelle étant guidée par une lumière en forme d'arc de cercle centré sur l'axe de pivotement de la lunette arrière, réalisée dans une plaque fixe par rapport à la caisse du véhicule.  In a preferred version of the invention, the rear window is pivotally mounted about a fixed axis and transverse to the longitudinal axis of the vehicle and located near the lower edge of the rear window, said mechanical link being constituted by a connecting rod with a crank connected to the rear window, the linkage of the connecting rod to the crank being guided by a circular arc-shaped light centered on the pivoting axis of the rear window, made in a fixed plate by relative to the vehicle's box.
Ce système bielle, lumière en arc de cercle et manivelle est particulièrement simple et permet de guider le pivotement de la lunette arrière tout en permettant de stabiliser celle-ci dans les deux positions.  This connecting rod system, arcuate light and crank is particularly simple and guides the pivoting of the rear window while stabilizing it in both positions.
De préférence, ladite plaque est sensiblement verticale et ladite articulation de la bielle à la manivelle est mobile dans la lumière en forme d'arc de cercle entre une position dans laquelle la lunette arrière est dressée vers le haut et une position dans laquelle la lunette arrière est située sensiblement horizontalement dans ledit logement.  Preferably, said plate is substantially vertical and said articulation of the crank rod is movable in the arc-shaped light between a position in which the rear window is raised upwards and a position in which the rear window is located substantially horizontally in said housing.
Dans un mode de réalisation particulièrement avantageux de l'invention, ledit mécanisme d'entraînement du toit comprend au moins un bras dont l'extrémité supérieure est reliée de façon articulée à une partie supportant la matière souple du toit et dont l'extrémité inférieure est reliée de façon articulée à une partie fixe de la caisse du véhicule, ce bras pouvant pivoter de l'avant vers l'arrière vers une position escamotée située dans ledit logement.  In a particularly advantageous embodiment of the invention, said roof drive mechanism comprises at least one arm whose upper end is hingedly connected to a portion supporting the flexible material of the roof and whose lower end is hingedly connected to a fixed part of the vehicle body, this arm being pivotable from front to rear to a retracted position in said housing.
Le pivotement du bras entraîne ainsi le déplacement du toit souple vers le logement arrière du véhicule et vice-versa.  Pivoting the arm thus moves the flexible roof to the rear housing of the vehicle and vice versa.
Dans un mode de réalisation particulièrement avantageux, ledit bras est relié à ladite bielle par une articulation espacée de l'articulation dudit bras à ladite partie fixe de la caisse du véhicule, de telle sorte que le pivotement du bras vers ladite position escamotée provoque le déplacement de la bielle et le déplacement de son articulation à ladite manivelle dans ladite lumière en arc de cercle.  In a particularly advantageous embodiment, said arm is connected to said connecting rod by a hinge spaced from the articulation of said arm to said fixed part of the vehicle body, so that the pivoting of the arm towards said retracted position causes the displacement of the connecting rod and the displacement of its articulation to said crank in said arcuate light.
De préférence, ledit mécanisme d'entraînement du toit comprend un second bras situé devant ledit bras relié de façon articulée à ladite partie supportant la matière souple du toit et à ladite partie fixe de la caisse, ces deux bras formant avec leurs articulations un parallélogramme déformable. Preferably, said roof drive mechanism comprises a second arm located in front of said arm articulately connected to said portion supporting the flexible material of the roof and said fixed part of the body, these two arms forming with their joints a deformable parallelogram.
Lorsque le toit est en position fermée, la matière souple est tendue entre la lunette arrière et ladite partie supportant la matière souple du toit et lorsque le toit est en position ouverte, la lunette arrière est située sous ladite partie supportant la matière souple et cette dernière est repliée entre cette partie et la lunette arrière.  When the roof is in the closed position, the flexible material is stretched between the rear window and said portion supporting the flexible material of the roof and when the roof is in the open position, the rear window is located under said portion supporting the flexible material and the latter is folded between this part and the rear window.
Dans un mode de réalisation également préféré de l'invention, ledit bras est relié à un organe de commande du pivotement de ce bras, le point de liaison entre cet organe et le bras étant situé dans la zone où sont situées l'articulation dudit bras à ladite partie fixe de la caisse et l'articulation de ladite bielle.  In a also preferred embodiment of the invention, said arm is connected to a control member of the pivoting of this arm, the point of connection between this member and the arm being located in the area where the articulation of said arm is located. to said fixed part of the body and the articulation of said connecting rod.
Cet organe de commande exerce une traction sur le bras qui fait pivoter celui-ci et en même temps commande le pivotement de la lunette arrière par le biais de la bielle reliée audit bras.  This control member exerts traction on the arm which pivots it and at the same time controls the pivoting of the rear window through the connecting rod connected to said arm.
D'autres particularités et avantages de l'invention apparaîtront encore tout au long de la description ci-après.  Other features and advantages of the invention will become apparent throughout the description below.
Aux dessins annexés, donnés à titre d'exemples, non limitatifs :  In the accompanying drawings, given by way of nonlimiting examples:
- la figure 1 est une vue latérale partielle, schématique montrant un véhicule selon l'invention équipé d'un toit souple escamotable, en position fermée, FIG. 1 is a partial schematic side view showing a vehicle according to the invention equipped with a retractable flexible roof, in the closed position,
- la figure 2 est une vue analogue à la figure 1 , le toit souple étant partiellement ouvert, FIG. 2 is a view similar to FIG. 1, the flexible roof being partially open,
- la figure 3 est une vue analogue aux figures 1 et 2, le toit souple étant complètement ouvert et rangé dans son logement.  - Figure 3 is a view similar to Figures 1 and 2, the flexible roof being completely open and stored in its housing.
Les figures 1 à 3 représentent schématiquement un véhicule automobile comportant un toit escamotable 1 en matière souple, telle que de la toile, équipé d'une lunette arrière 2.  Figures 1 to 3 show schematically a motor vehicle having a retractable roof 1 of flexible material, such as canvas, equipped with a rear window 2.
Ce toit escamotable 1 est déplaçable grâce à un mécanisme 3 d'entraînement du toit, entre une position fermée (voir figure 1 ) dans laquelle le toit 1 recouvre l'habitacle 4 du véhicule et une position ouverte (voir figure 3) dans laquelle le toit 1 est replié dans un logement 5 situé derrière l'habitacle 4.  This retractable roof 1 is movable by means of a mechanism 3 for driving the roof, between a closed position (see FIG. 1) in which the roof 1 covers the passenger compartment 4 of the vehicle and an open position (see FIG. 3) in which the roof 1 is folded into a housing 5 located behind the passenger compartment 4.
Comme montré par la figure 1 , lorsque le toit 1 est fermé, la lunette arrière 2 présente un bord inférieur 2a qui s'appuie sur une partie 6 de la caisse qui est adjacente au volet arrière 7. La lunette arrière 2 est entourée par un cadre rigide 8 qui est relié au toit souple 1 à sa partie supérieure et sur les côtés latéraux. As shown in Figure 1, when the roof 1 is closed, the rear window 2 has a lower edge 2a which rests on a portion 6 of the body which is adjacent to the rear door 7. The rear window 2 is surrounded by a rigid frame 8 which is connected to the flexible roof 1 at its upper part and on the lateral sides.
A l'avant le toit souple 1 est fixé à une traverse rigide 9.  At the front, the flexible roof 1 is fixed to a rigid cross member 9.
A chaque extrémité de cette traverse 9 est fixé un élément rigide 10 auquel est relié le mécanisme 3.  At each end of this crosspiece 9 is fixed a rigid element 10 to which the mechanism 3 is connected.
En position fermée chacun des éléments rigides 10 s'appuie contre une partie rigide 1 1 située au-dessus d'une porte latérale.  In the closed position each of the rigid elements 10 bears against a rigid portion 1 1 located above a side door.
Entre la traverse 9 et la traverse avant (non représentée) du véhicule située au-dessus du pare-brise s'étend une ouverture 12 qui peut être fermée par une toile 13 qui est représentée sur les figures 1 à 3 en position ouverte repliée vers la traverse 9.  Between the cross member 9 and the front cross member (not shown) of the vehicle located above the windshield extends an opening 12 which can be closed by a fabric 13 which is shown in Figures 1 to 3 in the open position folded towards the crossing 9.
Conformément à l'invention, le mécanisme 3 est directement relié à la lunette arrière 2 par une liaison mécanique rigide 14 permettant de faire pivoter la lunette arrière 2 de l'arrière vers l'avant (voir flèche F de la figure 2) lors du déplacement du toit 1 entre la position fermée et la position ouverte, comme montré par la flèche F1 de la figure 2.  According to the invention, the mechanism 3 is directly connected to the rear window 2 by a rigid mechanical connection 14 for pivoting the rear window 2 from the rear to the front (see arrow F in FIG. moving the roof 1 between the closed position and the open position, as shown by the arrow F1 in FIG.
La lunette arrière 2 est montée pivotante autour d'un axe 15 fixe transversal par rapport à l'axe longitudinal X du véhicule et situé près du bord inférieur 2a de la lunette arrière 2.  The rear window 2 is pivotally mounted about a transverse fixed axis 15 relative to the longitudinal axis X of the vehicle and located near the lower edge 2a of the rear window 2.
La liaison mécanique mentionnée plus haut est constituée par une bielle 14 articulée à une manivelle 16 reliée à la lunette arrière 2.  The mechanical connection mentioned above is constituted by a rod 14 articulated to a crank 16 connected to the rear window 2.
L'articulation 17 de la bielle 14 à la manivelle 16 est guidée par une lumière 18 en forme d'arc de cercle centré sur l'axe 15 de pivotement de la lunette arrière 2, réalisée dans une plaque 19 fixe par rapport à la caisse du véhicule.  The hinge 17 of the connecting rod 14 to the crank 16 is guided by a slot 18 in the form of a circular arc centered on the axis 15 of pivoting of the rear window 2, made in a plate 19 fixed relative to the box of the vehicle.
La plaque 19 est sensiblement verticale et l'articulation 18 de la bielle 14 à la manivelle 16 est mobile dans la lumière 18 en forme d'arc de cercle entre une position (voir figure 1 ) dans laquelle la lunette arrière 2 est dressée vers le haut et une position (voir figure 3) dans laquelle la lunette arrière 2 est située sensiblement horizontalement dans le logement 5.  The plate 19 is substantially vertical and the hinge 18 of the connecting rod 14 to the crank 16 is movable in the light 18 in the form of an arc of a circle between a position (see FIG. 1) in which the rear window 2 is raised towards the high and a position (see Figure 3) in which the rear window 2 is located substantially horizontally in the housing 5.
Dans l'exemple représenté, le mécanisme d'entraînement 3 du toit comprend un bras 20 dont l'extrémité supérieure est reliée de façon articulée en 21 à l'élément rigide 10 supportant la matière souple du toit 1 et dont l'extrémité inférieure est reliée de façon articulée en 22 à une partie fixe 23 de la caisse du véhicule. In the example shown, the driving mechanism 3 of the roof comprises an arm 20 whose upper end is hingedly connected at 21 to the rigid element 10 supporting the flexible material of the roof 1 and whose end lower is hingedly connected at 22 to a fixed portion 23 of the vehicle body.
Le bras 20 peut pivoter de l'avant vers l'arrière (voir figure 2) vers une position escamotée située dans le logement 5, comme montré sur la figure 3.  The arm 20 can pivot from front to rear (see Figure 2) to a retracted position in the housing 5, as shown in Figure 3.
Le bras 20 est relié à la bielle 14 par une articulation 24 espacée de l'articulation 22 du bras 20 à la partie fixe 23 de la caisse du véhicule, de telle sorte que le pivotement du bras 20 vers la position escamotée provoque le déplacement de la bielle 14 et de son articulation 17 à la manivelle 16 dans la lumière 18 en arc de cercle, comme montré par la flèche F3 de la figure 2.  The arm 20 is connected to the connecting rod 14 by a hinge 24 spaced from the hinge 22 of the arm 20 to the fixed part 23 of the vehicle body, so that the pivoting of the arm 20 towards the retracted position causes the displacement of the rod 14 and its articulation 17 to the crank 16 in the light 18 in an arc, as shown by the arrow F3 of FIG.
Dans l'exemple représenté, le mécanisme d'entraînement 3 du toit 1 comprend un second bras 25 situé devant le bras 20, relié de façon articulée en 26 à l'élément 10 supportant la matière souple du toit 1 et par une articulation 27 à la partie fixe 23 de la caisse.  In the example shown, the driving mechanism 3 of the roof 1 comprises a second arm 25 located in front of the arm 20, hingedly connected at 26 to the element 10 supporting the flexible material of the roof 1 and by a hinge 27 to the fixed part 23 of the box.
Les deux bras 20, 25 forment avec leurs articulations 21 , 22, 26, 27 un parallélogramme déformable dont la fonction est de maintenir l'élément rigide 10 sensiblement horizontal lors du déplacement du toit 1 vers son logement 5.  The two arms 20, 25 form with their hinges 21, 22, 26, 27 a deformable parallelogram whose function is to maintain the rigid element 10 substantially horizontal during the displacement of the roof 1 towards its housing 5.
Lorsque le toit 1 est en position fermée, comme indiqué sur la figure 1 , la matière souple du toit 1 est tendue entre le cadre 8 de la lunette arrière 2 et l'élément rigide 10 supportant le toit 1 .  When the roof 1 is in the closed position, as shown in Figure 1, the flexible material of the roof 1 is stretched between the frame 8 of the rear window 2 and the rigid element 10 supporting the roof 1.
Lorsque le toit 1 est en position ouverte, c'est-à-dire rangé dans son logement 5, la lunette arrière 2 est située (voir figure 3) sous l'élément rigide 10 supportant la matière souple et cette dernière est repliée entre l'élément 10 et la lunette arrière 2.  When the roof 1 is in the open position, that is to say stored in its housing 5, the rear window 2 is located (see Figure 3) under the rigid element 10 supporting the flexible material and the latter is folded between the element 10 and the rear window 2.
Les figures 1 à 3 montrent également que l'extrémité inférieure du bras 20 est reliée à un câble 28 de commande du pivotement de ce bras 20.  FIGS. 1 to 3 also show that the lower end of the arm 20 is connected to a cable 28 for controlling the pivoting of this arm 20.
Le point de liaison 29 entre ce câble 28 et le bras 20 est situé dans la zone où sont situés l'articulation 22 du bras 20 à la partie 23 fixe de la caisse et l'articulation 24 de la bielle 14.  The connection point 29 between this cable 28 and the arm 20 is located in the area where the hinge 22 of the arm 20 is located at the fixed part 23 of the body and the hinge 24 of the connecting rod 14.
Ce câble 28 peut être sollicité par un moteur électrique ou par un ressort pour assister l'ouverture du toit.  This cable 28 may be biased by an electric motor or by a spring to assist opening the roof.
Lorsque le toit 1 est en position fermée, comme montré par la figure 1 , l'ensemble, constitué par les bras 20, 25, les deux éléments 10 et la traverse 9, exerce du fait de sa masse sur la bielle 14 une force qui tend à stabiliser la position dressée de la lunette arrière 2 et à tendre la matière souple du toit 1 . When the roof 1 is in the closed position, as shown in FIG. 1, the assembly consisting of the arms 20, 25, the two elements 10 and the cross member 9, exerts, because of its mass on the connecting rod 14, a force which tends to stabilize the upright position of the rear window 2 and to tension the flexible material of the roof 1.
