Detailed description

[0021] The direction in which a motor vehicle moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called the transverse direction Y. The third direction, perpendicular to the other two, is called the vertical direction Z. Thus, a direct XYZ reference frame is used in which X is the longitudinal direction in the front-rear direction of the vehicle, therefore directed towards the rear, Y is the transverse direction directed towards the right and Z is the vertical direction directed upwards. The forward direction corresponds to the direction in which the motor vehicle usually moves in the longitudinal direction and is opposite to the rear direction.

[0022] There figure 1schematically illustrates a vehicle, in particular a motor vehicle 1, according to one embodiment. The motor vehicle 1 comprises a body 2. The motor vehicle 1, more precisely the body 2, further comprises a roof or roof 3. The roof 3 comprises an opening 80. Preferably, the roof 3 is fixed to and / or supported by the body 2. The motor vehicle 1 further comprises a sunroof 50. The sunroof 50 is arranged at the roof 3 so as to obstruct, in a closed position PF of the sunroof, the opening 80 formed in the roof 3.

[0023] For example, the opening 80 is arranged rather at the front of the pavilion 3 as illustrated in the figures 1 to 4 Alternatively, the opening 80 can be provided substantially in the middle of the roof 3 in the longitudinal direction, or at the rear of the roof in this same direction.

[0024] Alternatively, a first opening is provided at the front while a second opening is provided further to the rear of the roof 3. In this case, a first sunroof is intended to obstruct or uncover the first opening while a second sunroof is intended to obstruct or uncover the second opening. Alternatively again, a single sunroof may obstruct or uncover the first and second openings simultaneously or substantially simultaneously. Obviously, more than two openings are possible (embodiments not illustrated).

[0025] The motor vehicle 1 further comprises an arrangement 10.

[0026] The arrangement 10 comprises a guide device 20 of the sunroof 50.

[0027] As illustrated in the figure 1, the guide device 20 comprises a first guide means 30 extending longitudinally or substantially longitudinally at or above the pavilion 3 on the right side. The guide device 20 comprises a second guide means 40 extending longitudinally or substantially longitudinally at or above the pavilion 3 on the left side.

[0028] Advantageously, the first guide means 30 is, or comprises, a first roof bar 33 arranged to the right of the roof 3. Advantageously, the second guide means 40 is, or comprises, a second roof bar 45 arranged to the left of the roof 3.

[0029] As will be detailed later, the sunroof 50 is movable relative to the roof 3 between a closed position PF ( figures 1 , 5 , 7 and 8 in particular) in which the opening 80 is obstructed by the sunroof 50 and at least one intermediate opening position POI ( figures 2 And6 in particular) in which the opening 80 is at least partially obstructed by the sunroof 50. Advantageously, this mobility of the sunroof makes it possible to reach a fully open position POT ( Figures 3 and 4 in particular) in which the sunroof 50 is not, or almost not, opposite the opening 80.

[0030] As illustrated on the figures 10 , 12 , 13 , 14 , 15 And 16 in particular, the first guide means 30, on the right side of the vehicle, comprises a first groove 31 and a second groove 32. Preferably, as illustrated in the figures 11 And 13, the first groove 31 extending in a first plane P1 and the second groove 32 extending in a second plane P2. The first and second planes P1, P2 are distinct, parallel and extend vertically and longitudinally. For example, the first groove 31 extends on either side of the first plane P1, for example being centered or substantially centered on either side of the plane P1. For example, the second groove 32 extends on either side of the second plane P2, for example being centered or substantially centered on either side of the plane P2.

[0031] As illustrated on the figures 17 , 18 and 19, the second guide means 40, on the left side of the vehicle, comprises a third groove 43 and a fourth groove 44. Preferably, the third groove 43 extends in a third plane (not shown) and the fourth groove 44 extends in a fourth plane (not shown). The third and fourth planes are distinct, parallel and extend vertically and longitudinally. For example, the third groove 43 extends on either side of the third plane, for example being centered or substantially centered on either side of this plane. For example, the fourth groove 44 extends on either side of the fourth plane, for example being centered or substantially centered on either side of this plane.

[0032] The arrangement 10 comprises the guide device 20, composed in particular of the first and second guide means 30, 40, and the opening roof 50.

[0033] Preferably as shown in the figure 20, the sunroof 50 comprises a frame 51. The frame 51 may be metallic, for example made of steel and / or aluminum alloy. Advantageously, the sunroof 50 comprises a panel 52. The panel 52 may comprise a glazed surface 53, for example translucent or transparent, so as to provide greater clarity within the passenger compartment. In addition, a concealing means, for example a curtain, may be fitted to the sunroof so as to allow the glazed surface to be concealed if necessary, for example in the event of troublesome sunlight. For example, the panel 52 is assembled on the frame 51 by gluing.

[0034] As illustrated in the figure 20, the sunroof 50 comprises first sliding and / or rolling means 60 arranged to the right of the sunroof 50 and intended to cooperate with the first guide means 30. The sunroof 50 comprises second sliding and / or rolling means 70 arranged to the left of the sunroof 50 and intended to cooperate with the second guide means 40. More precisely, the first sliding and / or rolling means 60 comprise a first roller 61 and a second roller 62 intended to cooperate with the first guide means 30. Advantageously, the first roller 61 and the second roller 62 roll and / or slide respectively along and / or on and / or in the first groove 31 and the second groove 32. The second sliding and / or rolling means 70 comprise a third roller 73 and a fourth roller 74 intended to cooperate with the second guide means 40.Advantageously, the third roller 73 and the fourth roller 74 roll and / or slide respectively along and / or on and / or in the third groove 43 and the fourth groove 44. The first sliding and / or rolling means 60 comprise a first axis of rotation 63 of the first roller 61 and a second axis of rotation 64 of the second roller 62. The second sliding and / or rolling means 70 comprise a third axis of rotation 71 of the third roller 73 and a fourth axis of rotation 72 of the fourth roller 74. Preferably, the first and second axes of rotation 63, 64 are fixed on the right side of the frame 51 and the third and fourth axes of rotation 71, 72 are fixed on the left side of the frame 51. Advantageously, the first and third axes of rotation 63, 71 are coaxial or substantially coaxial. Likewise, advantageously, the second and fourth axes of rotation 64, 72 are coaxial or substantially coaxial.Preferably, given the configuration of the grooves of the first and second guide means 30, 40 extending mainly longitudinally, the axes 63, 64, 71, 72 extend transversely or substantially transversely.

[0035] Thus, the first guide means 30 and the second guide means 40 cooperate respectively with the first sliding and / or rolling means 60 and the second sliding and / or rolling means 70. This cooperation makes it possible to make the sunroof 50 movable relative to the roof 3 between the closed position PF in which the opening 80 is obstructed by the sunroof 50 and the at least one intermediate opening position POI in which the opening 80 is at least partially closed by the sunroof 50. Furthermore, this mobility makes it possible to obtain the total opening position POT in which the sunroof 50 completely or substantially completely uncovers the opening 80. Obviously, conversely, the mobility of the sunroof makes it possible to move from the at least one intermediate position POI or from the total opening position POT to the closed position PF.

[0036] Preferably as shown in the figures 21 , 22 ,23 , 24 and 25 , the sunroof 50 comprises a second means 92 for locking and unlocking the sunroof 50 in the at least one intermediate opening position POI or in the total opening position POT. The sunroof 50 further comprises a first means 91 for locking and unlocking the sunroof 50 in the closed position PF, as illustrated in the figures 26 and 27 Advantageously, the sunroof 50 comprises a retractable handle 94 cooperating with the roof 3 to lock or unlock the first locking and unlocking means 91 of the sunroof 50 in the closed position PF. The retractable handle 94 also makes it possible to lock or unlock the second locking and unlocking means 92 of the sunroof 50 in the at least one intermediate opening position POI or in the total opening position POT.

[0037] As illustrated in particular on the figures 21 to 23, the sunroof 50 comprises a fixing lug 54 for the retractable handle 94. For example, the fixing lug 54 of the fixed knuckle or yoke type is arranged on the frame 51 of the sunroof.

[0038] Preferably, the box 2 comprises a seal 83 arranged at a periphery 81 of the opening 80, as illustrated in the figure 3 In the closed position PF of the sunroof, the seal 83 ensures sealing at a periphery 55 of the sunroof which is opposite or substantially opposite the periphery 81 of the opening 80.

[0039] As illustrated in the figure 25 , in the open position of the sunroof and the retractable handle 94 locked, the perimeter 81, or only part of the perimeter 81, of the opening 80 comprises a rebate 82 (see figure 13also). Preferably, the rebate 82 extends vertically or substantially vertically. The rebate 82 ensures the positioning and / or holding in place of the seal 83. Note that the seal 83 may comprise a frame.

[0040] Preferably as shown in the figures 22, 23 , 24 and 25 , the roof 3 comprises a rear tab 5 arranged at the rear of the opening 80. The tab 5 is capable of cooperating with the retractable handle 94. More precisely, preferably the retractable handle 94 comprises a light or an orifice or a locking notch 95. Thus, for example, to move from the unlocked position to the fully open position POT ( figure 24 ) to the locked position in the fully open position POT ( figure 25), the retractable handle 94 is pivoted once the tab 5 is at least partially housed within the orifice 95. Note that in this embodiment, the rear tab 5 is fixed relative to the roof 3. For example, the second locking / unlocking means 92 comprises a connecting rod 96. The connecting rod 96 is articulated on the one hand relative to the sunroof 50 around an axis A1, preferably at the level of the fixed knuckle 54. The connecting rod 96 is articulated on the other hand relative to the retractable handle 94 around an axis A2. By pivoting the retractable handle 94, we mean simultaneous or substantially simultaneous pivoting of the connecting rod 96 around the axes A1 and A2. Indeed, such pivoting causes the handle 94 to pivot. Preferably, the axes A1 and A2 are parallel, distinct and extend transversely or substantially transversely.

[0041] Alternatively, the rear tab may be movable relative to the roof 3 while the handle is fixed relative to the sunroof.

[0042] As illustrated on the figures 26 and 27 , a front tab 4, fixed to the roof 3, at the front, makes it possible to lock the handle in the closed position PF of the sunroof 50. More precisely, the front tab 4 cooperates with a locking point 97 provided at one end of the handle 94. This locking point is for example a cylindrical part, for example an axis of axis parallel to the axes A1, A2 of the connecting rod 96 used for locking in the closed position PF.

[0043] In summary, the sunroof 50 operates manually by being guided by means of the longitudinal bars 33, 45. Preferably, the sunroof has only two positions that can be locked, namely the closed position PF and the fully open position POT. Intermediate opening positions POI are advantageously possible without being able to be locked in position. Indeed, preferably, only the two extreme positions (PF, POT) are held in position thanks to the retractable handle 94 cooperating with the body 2, more precisely the roof 3, via front rear tabs 4, 5. Preferably, the front tab 4 is arranged on or near a front roof crossmember and the rear tab 5 is arranged, preferably, on or near the rear roof crossmember 6.

[0044] Concerning the mobility of the sunroof, as mentioned previously, the grooves or rails or tracks 31, 32, 43, 44 included or arranged in the structures of the roof bars 33, 45 guide the sunroof equipped with rollers or wheels or casters 61, 62, 73, 74. The sunroof 50 preferably comprises a metal frame 51 and glass glued thereon. On each side of the frame, the axles 63, 64, 71, 72 equipped with the rollers are fixed to the frame, for example by welding. As illustrated in the figure 11 , the longitudinal roof bars 33, 45 are for example fixed to the body 2 and / or to the roof 3, by screwed systems and / or screws 7. The roof bars preferably each comprise a rigid support, for example made of plastic, the grooves or rails, an external trim 35 ( figure 9) and a peripheral sealing support. More precisely, the kinematics is obtained by means of the two grooves 43, 44 in or on the left longitudinal bar 45 and the two grooves 31, 32 in or on the right longitudinal bar 33 (symmetrical from the left with respect to a vertical and longitudinal median plane PM illustrated on the figure 2 ). Thus, preferably, the first groove 31 is associated with the first roller 61, the second groove 32 is associated with the second roller 62, the third groove 43 is associated with the third roller 73 and the fourth groove 44 is associated with the fourth roller 74.

[0045] The first and third grooves 31, 43 are inclined forwards relative to the roof 3 of the vehicle. During the closing movement, the front of the sunroof 50 approaches linearly the opening 80 by following the profile of the first and third grooves formed in the roof bars. The front end of the first and third grooves open close to the roof, in particular vertically at the same level as the roof. The second and fourth grooves 32, 44 run along a vertical plane not having the inclination of the first and third grooves. The second and fourth grooves 32, 44 run longitudinally along a substantially rectilinear vertical plane parallel to the roof.Due to the different profiles between the first and second grooves of the first sliding and / or rolling means 60, respectively the third and fourth grooves of the second sliding and / or rolling means 70, the sunroof is able to take an inclined position relative to the roof lining at the end of the movement towards its closed position or at the start of the movement towards an open position.

[0046] Advantageously, as illustrated on the figures 6 , 9 , 10 , 12 , 13 , 15 , 16 , 18, the second groove 32 and the fourth groove 44 respectively comprise a guide or track or groove 36, 46 at the front ends of each of these grooves. Such guides 36, 46 allow non-rectilinear kinematics, which may be modified, during movement. In addition, these two guides 36, 46 ensure the “diving” of the sunroof 50 when moving from an open position (POI or POT) to the closed position PF. Indeed, the sunroof is guided towards its housing, within the opening 80, in the roof 3. Conversely, when moving from the closed position PF to an open position, the guides 36, 46 ensure an offset in the vertical direction or substantially in this direction so as to clear the rear of the sunroof 50 from the opening 80.

[0047] Note that the second groove 32 advantageously comprises a notch 37 at its rear end, as illustrated in the figure 2. The fourth groove 44 advantageously comprises a notch 47 at its rear end, as illustrated in the figure 19 . Each notch 37, 47 extends for example downwards and backwards. The notches 37, 47 facilitate blocking or locking in the fully open position. JAR of the sunroof. Indeed, in this open position of the sunroof, the second and fourth rollers 62, 74 are housed, at least partially, in these notches 37, 47. This has the effect of wedging them and consequently of participating in the immobilization of the sunroof 50 in the fully open position POT.

[0048] As mentioned previously, the frame 51 is preferably equipped with the tab 54 for fixing the handle 94 (latch type) to ensure a connection with the roof 3 and keep the sunroof in the open or closed position. The roof 3, perforated via the opening 80, receives the sunroof whose shape is specific to allow the sunroof to be flush. The seal is ensured by the seal 83 attached to the rebate 82 formed around the opening 80 on the roof 3. The movement of the roof 50 when closing, obtained in part by the second and fourth rollers 62, 74 cooperating with the guides 36, 46, causes the sunroof to plunge along a specific axis which compresses the seal 83.

[0049] Advantageously, the roof 3 comprises at least one support, for example made of plastic, intended to hold the gasket of the seal 83 in place while ensuring compliance with clearances and vision (open and closed sunroof). At the rear of the opening or opening 80, the rear tab or tongue 5 is preferably fixed to the central structure, for example on or at the level of a crosspiece 6 stiffening for example the roof, as illustrated in the figure 22 . As mentioned previously, the rear tab 5 cooperates with the retractable handle 94 to hold the sunroof in the fully open position POT.

[0050] Note that the handle allows the sunroof to be locked, both in the fully open position POT and in the closed position PF (via the front tab 4 cooperating with the axis 97 of the handle 94), and a crushing of the seal 83 when closing.

[0051] Furthermore, the longitudinal roof bars 33, 45 retain their original function and are therefore available to support loads or transverse roof bars, for example prior to the installation of a roof box. Advantageously, the shape of the bars 33, 45 can be stylized without impacting the guiding part of the sunroof provided by the grooves. One or more trims 35 may be provided for aesthetic and / or aerodynamic purposes.

[0052] In summary, the solution offers a technically simple sunroof, in particular by being free of electrical and / or electronic parts and / or motorization and / or cables and / or connectors. In addition, the solution does not require reinforcement of the body and / or the roof. Indeed, it comprises, for example, the frame 51, the panel 52 and / or the glazed surface 53, the four axes equipped with the four rollers and the retractable handle 94. In the case of a glazed surface, this is preferably made of tempered or laminated glass, possibly equipped with a solar film or a self-obscuring film, tinted or transparent. A plate, made of sheet metal for example, may possibly cover the sunroof.

[0053] The solution thus eliminates the need for a specific frame or cassette for the movement of the sunroof, with the operations being carried out manually.

[0054] The weight is reduced. The interior architecture is less impacted and the "headroom", or height under the roof, is increased. Its simple shape and the particularities mentioned above make it particularly economical to install on a vehicle. This results in a small difference in manufacturing costs between a vehicle equipped with a sunroof and a vehicle without one.

[0055] As a note, the solution according to the invention therefore achieves the desired objective of making a motor vehicle sunroof less expensive and less complex and has the following advantages: It can be used on all types of motor vehicles, regardless of the range; it can be applied to public transport vehicles, boats or even construction or agricultural machinery, or even to building openings.
