Description

Glazed pavilion sliding sliding panel and entrebâillant. FIELD OF THE DISCLOSURE The field of the invention is that of motor vehicles, and in particular vehicles having a large glazed surface, for example at the roof level. More specifically, the invention relates to such closure devices comprising at least one opening cooperating with a movable sliding glass panel and entrebâillant, and in particular devices known under the name "bay flush", designed to be mounted flush with the bodywork.

In the context of the present patent application, the term "glazed panel" means any panel, fixed or mobile relative to the body, substantially transparent or translucent, participating bay clear. Such a panel may be made of glass or any suitable material, such as polycarbonate.

In certain embodiments, the panel may consist of several flush elements, seen from the outside. Where appropriate at least one of these elements may be opaque and for example metal or plastic. Moreover, the edges of a glazed panel can be opacified, for example by screen printing.

A device according to the invention may further equip a bay formed in a substantially horizontal portion other than the flag of the vehicle. 2. Techniques of the Prior Art It is currently desired, in the field of motor vehicles, to offer more and more glazed surfaces. In particular, vehicles with a roof equipped with one or more glazed elements have been proposed. In some cases, the entire roof is made of glass, or a similar material allowing light to pass, including the sun's rays. These glazed surfaces give an impression of volume and comfort to the occupants of the vehicle and allow the interior of the cabin to be brighter.

Solutions have also been proposed to clear openings in such a pavilion, in particular to be able to form a sunroof. Thus, a common technique to release an opening in the flag is to tilt a movable window, mounted on a frame, to the outside of the vehicle around an axis integral with the flag to release a passage between the window and the frame. Control of the tilting of the mobile panel is conventionally implemented using rods. Another sunroof technique also used is to make the sliding pane sliding above the flag, in a plane substantially parallel to the plane of the flag.

It has also been proposed to combine these two approaches, to alternately allow the movable panel to be ajar, or to completely release the opening in the roof by retraction of the movable panel. A disadvantage of these known techniques is that they harm the aerodynamics of the motor vehicle.

Another disadvantage of these known techniques is that they require complex means to control the different movements to be applied to the movable panel as appropriate: - release or sway, to move from the closed position in which the movable panel is in the plan of the fixed panel of the pavilion, to a parallel plane allowing the sliding; - Sliding to move the movable panel away from the opening, and bring it back above it; - tilting to ensure cracking. These distinct movements assume a high number of moving parts, and therefore a relatively large size and weight, as well as a relatively complex assembly, adjustment and maintenance (being reminded that, in particular, the sealing in the closed position must in all the cases to be effectively insured). The motorization of these different movements is also complex.

The size and complexity of these means is a disadvantage all the more important that the flag is glazed, since it is then necessary to hide, using screen printing, the various mechanical parts, which goes against the goal of maximizing the glazed area, or clear bay. 3. OBJECTIVES OF THE INVENTION The object of the invention is notably to overcome these disadvantages of the prior art. More specifically, the object of the invention is to provide a glazed shutter device for a bay formed in a motor vehicle, and in particular a glazed roof, in which the movable panel can be ajar or slidably moved in a simple and effective manner. and reliable, while optimizing the aerodynamics of the motor vehicle. Thus, an object of the invention is to provide a technique to ensure the cracking and sliding using means having a footprint and reduced weight, and a small number of parts.

Another object of the invention is to provide such a technique, allowing actuation and motorization, at least in a certain embodiment, which is particularly simple. Yet another object of the invention is to maximize the glass surface, or bay clear. 4. Objective of the invention These objectives, as well as others which will appear later are achieved with the aid of a motor vehicle glazed roof, comprising a fixed part and a movable panel with respect to the fixed part, between a closed position, in which it closes an opening formed in or next to said fixed part, and at least one ventilation position, in which said opening is at least partially released, the movable panel being guided by two rails in the vicinity of each side edge of said movable panel, respectively. According to the invention, the flag comprises means for tilting said movable panel, imparting a tilting movement, towards the interior of the passenger compartment of the motor vehicle, of the part of the movable panel closest to the front of the vehicle, said distal end, the other end of said movable panel, said proximal end, remaining substantially immobile. Thus, the invention proposes to interlock the movable panel of a sunroof towards the interior of the vehicle to release an opening in the roof.

This cracking is to tilt the portion of the moving window located towards the front of the vehicle, the other end of the movable panel remaining substantially immobile. This approach allows to ventilate or ventilate the cabin of the vehicle causing little aerodynamic disturbances.

Advantageously, each of said rails carries at least one shuttle guided in translation in said rail, said shuttle having two guide tracks (namely a first guide track and a second guide track) cooperating respectively with a front pin and a rear pin. integral with said movable panel, said guide tracks being configured to ensure, when the shuttles are moved in said rails in a first displacement zone, said tilting movement. The control of the tilting of the movable panel being implemented by means of pins secured to the movable panel and sliding shuttles in guide rails, the solution of the invention requires a reduced number of moving parts, and therefore a space requirement and a weight less important than the solutions of the prior art. With a movement in one direction of the shuttles, it is possible not only to ensure the opening and closing of the movable panel, sliding parallel to and below the fixed panel and movement to come in the plane of the panel fixed, in the closed position, but also a crank function of the movable panel, from this closed position. This mechanism allows complex kinematics, for the mobile panel, from a simple movement, and therefore easily controllable and motorized, shuttles, with a small number of simple and inexpensive elements. According to a particular embodiment, the displacement of said shuttles ensures: in a second zone of displacement, a tilting movement, with respect to the fixed part, of the other part of the movable panel, said proximal end, towards the inside of the passenger compartment of the motor vehicle; - In a third movement zone, a sliding movement of said movable panel relative to said fixed portion parallel to the rails and the fixed portion side facing the interior of the passenger compartment of the vehicle. In a particular embodiment, the first track of the shuttle has: a first portion extending parallel to the axis of movement of the shuttle in which the front pin is in said closed position; a second portion inclined with respect to the axis of displacement of said shuttle, from the first portion, in which the front pin moves during the beginning of said tilting of the distal end of said movable panel; a third portion extending parallel to the axis of movement of the shuttle, from the second portion, in which the front pin is at the end of said tilting of the distal end of said movable panel.

Advantageously, the front pin moves in said third portion during the tilting of the proximal end of said movable panel and is in said third portion during the sliding movement of said movable panel. In a particular embodiment, the second track of the shuttle has: a first portion extending parallel to the axis of movement of the shuttle in which the rear pin is in said closed position; a second portion inclined with respect to the axis of displacement of said shuttle, from the first portion in which the rear pin moves at the beginning of said tilting of the distal end of said movable panel; a third portion extending parallel to the axis of movement of the shuttle, from the second portion in which the rear pin is at the end of said tilting of the distal end of said movable panel. Preferably, the second track of said shuttle has a fourth portion, in the extension of said third portion, in which said rear pin moves, during the tilting of the proximal end of said movable panel and remains placed during the sliding movement of said panel mobile. In a particular embodiment, each of said rails carries a front shuttle and a rear shuttle respectively guided in translation in said rail, each of said front and rear shuttles respectively having a guide track cooperating respectively with a front pin and a rear pin. integral with said movable panel. The invention also relates to motor vehicles equipped with a roof as described above. 5.

DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION The invention thus relates to a device for closing off a bay of a motor vehicle, formed in or forming a glazed roof. The embodiment described below therefore relates to a glazed roof.

As illustrated in FIGS. 1A to 1C, the glazed roof is a pre-assembled assembly 11 comprising: a fixed panel 111, whose edges are dimensioned to be secured to the corresponding edges of the bodywork 12 of the vehicle, or of its chassis , of which only the upper part is illustrated, for example by gluing; a movable panel 112, movable relative to the fixed panel 111, for closing or releasing an opening 13 defined adjacent to the fixed panel 111; means described in more detail below (rails, pins, tracks, motorization ...) for controlling the movement of the movable panel 112. In known manner, in order to release the opening 13, the movable panel 112 is suitable to be moved towards the rear of the vehicle by sliding in rails (not shown) integral with the fixed part 111 and located on either side of the movable panel 112. In the closed position of the sunroof illustrated in FIG. 1A, the movable panel 112 is in the plane or continuity of the fixed panel 111. It seals tightly, seals (not shown) being provided for this purpose, the opening 13 formed in the roof 11, and is flush with the fixed panel 111. It can also be flush or substantially flush with the windshield of the vehicle and with a part or cross member, for example a cross. In the position illustrated in Figure 1B, the opening 13 is partially disengaged, the movable panel 112 having been moved relative to the fixed panel 111, and placed substantially parallel thereto within the vehicle. The opening of the sunroof illustrated in FIG. 1B, starting from the position illustrated in FIG. 1A, is effected by a clearance of the movable panel 112 below the opening 13 in two stages, then by a displacement in translation. , or sliding, of the movable panel 112 towards the rear of the vehicle.

In addition to this opening movement, it is expected that the sunroof can be ajar towards the interior of the vehicle to provide an opening ventilation or ventilation of the passenger compartment of the vehicle (Figure 6 illustrates with arrows the circuit of ventilation of the passenger compartment in the half-open position of the movable panel 112). This approach makes it possible to optimize the aerodynamics of the motor vehicle. To do this, and as will be described in detail later, operates a mechanism that causes the vehicle to tilt the portion of the movable panel 112 closest to the front of the vehicle about an axis placed substantially in the plane of the fixed panel 111, to take a half-open position (illustrated in Figure 1C). FIGS. 2A to 2D show the movement kinematics of the mobile panel 112. Unlike the opening solutions of the mobile panel of the prior art which implement a movement along an axis perpendicular to the plane defined by the fixed panel, or although a swaying movement, the clearance of the movable panel 112 below the opening 13 is implemented in two stages, namely: - a descent of the portion of the movable panel 112 closest to the front of the vehicle , called the distal end, which pivots about a fictitious axis located at the rear end of the movable panel 112 (FIGS. 2A to B), then - a descent on the other side of the movable panel, called the proximal end, which pivots around a real axis located at the front pin of the movable panel 112 (Figures 2B to 2C).

In other words, the movable panel 112 is pivotally mounted along a first transverse axis located near its rear edge and along a second transverse axis located near its front edge. The movable panel 112 is then in intermediate disengagement position and extends inside the passenger compartment (FIG. 2C), that is to say below the fixed panel 111, facing the opening 13 .

From the intermediate position of clearance (Figure 2C), the movable panel 112 can be moved in translation towards the rear of the vehicle to the open position (Figure 2D) in which the movable panel 112 extends away from the opening 13 and is stored below the fixed panel 111, in particular to optimize the isodynamics of the motor vehicle. The movable panel 112 can slide while being guided in the rails located on either side of the movable panel 112 in a substantially horizontal direction, in a sliding plane, substantially parallel to the plane of the roof 11, between the intermediate position of release (Figure 2C) in which it is facing the opening 13 and cleared thereof and one or more position (s) opening. The closure of the movable panel 112 firstly comprises a sliding from right to left, to bring the movable panel 112 to the vicinity of the opening 13 (the movable panel 112 moves towards the distal end of the vehicle), in the intermediate position of clearance (Figure 2C).

It is easily understood that from this intermediate position of release, the movable panel 112 can be moved to the closed position of the sunroof (FIG. 2A) by raising the proximal end of the movable panel 112 (FIG. 2B) and then the distal end of the movable panel 112 (Figure 2A) which causes a compression of the sealing gasket sealing the opening 13. In this closed position, and locked (Figure 2A), the movable panel 112 is in the same plan that the fixed panel 111, and closes the opening 13. To obtain the cracking of the movable panel 112 relative to the fixed panel frame 111 from this closed position of Figure 2A, a tilting is applied to the movable panel 112 causing the lowering relative to the fixed portion of the distal end of the movable panel 112. This is illustrated in Figure 2B. It should be noted that the terms "plane", "parallel" and "perpendicular" should be interpreted broadly. Indeed, as it appears in the figures, the flag 11 may be substantially curved in one or more directions.

In this case, the "plane" must be interpreted as being the (curved) reference surface defined by the horn 11. As mentioned above, the movable panel 112 is guided relative to the fixed panel 111 by two guide rails placed on one side. and other of the opening and reported on the face of the fixed glazing panel 111 facing the interior of the vehicle. More specifically, the different movements of the movable panel 112 are controlled from pins (or sliding elements) integral with the movable panel 112. Two front pins 21 and rear 22, disposed on each side of the movable panel 112, cooperate with guide tracks 31, 32 which are carried in this example by a single shuttle N, as shown in Figures 7A and 7B. These N shuttles, whose movement can be easily motorized, for example using a "push / pull" cable, are movable in a single direction, along and inside the guide rails (not shown). which are secured to the fixed part 111. The training N shuttle is preferably linked. In other words, for each guide rail, the shuttle N carries two guide tracks, namely a first guide track 31 and a second guide track 32, cooperating respectively with a pin 21, 22 integral with an edge. Lateral of the movable panel 112. In a variant (not shown), the guide tracks 31, 32 are carried by front and rear shuttles respectively. In this case, for each guide rail, each of the two front and rear shuttles carries a guide track 31, 32 cooperating with a pin 21, 22 integral with a lateral edge of the movable panel 112, driving the shuttles forward and rear being linked (the front and rear shuttles are for example connected by connecting means). FIGS. 5A to 5C schematically illustrate the position of the front and rear pins 21, 22 of a lateral edge of the movable panel in the corresponding guide tracks 31, 32 of the shuttle N (the position of the placed pins of the the other side of the moving panel is identical), each pin being guided in the corresponding track of the shuttle N as the latter moves in the associated guide rail. The guide tracks 31, 32 of the N shuttles thus make it possible to control the passage of the movable panel 112 of the plane of the fixed panel 111, in the closed position (FIG. 2A), to a neighboring lower plane (FIG. 2C) when the N shuttles are moved. from the front of the vehicle to the rear of the vehicle in the corresponding rails. FIG. 5A shows, on the left, the position of the front pin 21 of the mobile panel 112 in the track 31 of the shuttle N, and on the right, the position of the rear pin 22 of the mobile panel 112 in the track 32 of the shuttle N , in the closed position of the sunroof (Figure 2A). The front pin 21 is located in a first portion 311, parallel to the axis of the rail, of the track 31 of the shuttle N and the rear pin 22 is located in a first portion 321, parallel to the rail axis, of the track 32 of the shuttle N. Figures 7A and 7B are respectively a partial view showing the position of the front and rear pins 21, 22 of a lateral edge of the movable panel 112 in the guide tracks 31, 32 of the shuttle N , the movable panel being in the closed position. FIG. 5B shows the position of the front pin 21 of the movable panel 112 in the track 31 of the shuttle N (left) and the position of the rear pin 22 of the movable panel 112 in the track 32 of the shuttle N (right), in the half-open position of the sunroof (Figure 2B). It will be understood that the shuttle N, and therefore the corresponding tracks 31 and 32, have moved from the front of the vehicle towards the rear of the vehicle in the rails, and that the front pin 21 has been guided downwards in a second inclined portion 312 of the track 31 of the shuttle N and is located in a third portion 313, parallel to the axis of the rail. The rear pin 22 has been guided slightly downwards in a second portion 322 slightly inclined and is located in a third portion 323, parallel to the axis of the rail, of the track 32 of the shuttle N. Thus, the proximal end of the movable panel 112 remained in the plane of the fixed panel 111, while the distal end of the movable panel 112 has tilted inwardly of the passenger to take the interlocked position (Figure 2B). FIG. 5C shows the position of the front pin 21 of the mobile panel 112 in the track 31 of the shuttle N (left) and the position of the rear pin 22 of the mobile panel 112 in the track 32 of the shuttle N (right), in the intermediate position of release of the sunroof (Figure 2C). The front pin 21 has been guided in the third portion 313, parallel to the axis of the rail, of the track 31 and is at the closed left end of this third portion 313. The rear pin 22 has been guided downwards. in a fourth portion 324 inclined and is in abutment with the closed lower end of this fourth portion 324. Thus, the distal end of the movable panel 112 remained in the same plane, while the proximal end of the movable panel 112 has tilted inwardly of the passenger compartment and has substantially aligned with the distal end to take the intermediate position of clearance (Figure 2C). Therefore, if the shuttles N continue to move in the associated guide rail, the pin 22, which is in abutment with the lower end of the fourth portion 324 of the rear track 32, and therefore the movable panel 112, are slidably driven to the open flag position (Figure 2D). Each shuttle N thus drives the pins 21, 22 corresponding, the latter allowing sliding movement of the movable panel.

It can thus be seen that, with a movement of the N-shuttles in one direction (parallel to the rails), the different movements of the movable panel 112 can be controlled. In a first zone, this movement of the shuttles N controls the cracking and the movement towards the intermediate position of clearance of the movable panel 112. In a second zone, it controls the sliding of the movable panel 112. Of course, the movement of the shuttles N in the other direction (that is to say from the rear to the front of the vehicle), causes the closing of the movable panel 112. Advantageously, such a flag comprises locking means of the movable panel 112 in at least a predetermined position. Thus, the opening of the pavilion can be kept closed simply and efficiently.

It can further be provided that the movable panel 112 can be locked in several positions of partial opening and / or complete flag, using the same means. As illustrated in FIGS. 3 and 4, the frame of the movable panel 112 carries a gutter 41 on its edges, to receive the rain or condensation water deposited on the surface of the movable panel 112 when the opening of the roof 10 is closed by the movable panel 112. The detail of a section of the gutters 41, front and rear of the movable panel, is shown in section in Figures 3 and 4 respectively, the movable panel being partly clear of the opening of the pavilion (that is to say in the half-open position). Each gutter 41 carries a seal 48 whose lip is intended to come into contact with the lower surface (that is to say the surface facing the interior of the passenger compartment of the vehicle) of the fixed panel 111 when the movable panel 112 closes the opening 13. In the interlocked position of the movable panel 112, only the lip of the seal 48 of the rear groove 41 is in contact with the lower surface of the fixed panel 111 (Figure 4). Conventionally, the rain or condensation water settling on the surface of the movable panel 112 is guided and discharged through the guide rails. In the illustrated embodiment, the movable panel takes position next to the fixed part, to form the glazed roof (in the closed position).

In other embodiments, the fixed part may have a contour corresponding to the outline of the roof, the opening being then defined in this fixed part.
