The curtain is wound on a drum (21) fixed relative to the roof and has an edge traction bar (22). The panel opens whilst the panel remains closed and the panel opens whilst the curtain is open. The curtain is held closed by two driving points against a spring which winds it on the drum so that the panel can be maneuvered by two other driving points which are displaced in the same way as the first.

Description

VEHICLE PAVILION CONFIGURATION DEVICE

  AUTOMOTIVE, COMPRISING A CURTAIN AND A SLIDING PANEL

MOVED BY THE SAME MOTOR.

  The invention relates, in general,

  fitting out motor vehicle pavilions.

  More specifically, the invention relates to a motor vehicle roof configuration device, comprising an opening cut out in the roof, a movable curtain, a sliding panel, and means for actuating the curtain and the panel, the curtain being rolled up. selectively on a drum fixed relative to the roof, being bordered by a draw bar parallel to the drum, and selectively adopting, by displacement of the draw bar in a direction of movement and in an opening or closing direction, a configuration blackout in which this curtain is unwound from the drum and covers the opening, a release configuration in which it is wrapped around the drum and releases the opening, or any intermediate configuration, and the sliding panel selectively adopting, by sliding in the direction of movement and in the opening or closing direction, a closed position in which it closes the opening, an open position in which it releases the opening, or a

any intermediate position.

  Given the needs expressed by customers in the automotive sector, and production rates, all innovations in this area must overcome the many constraints they encounter, particularly in terms of simplicity, reliability, as well as weight reduction and congestion. Thus, in the case where the roof of a motor vehicle is equipped with both a curtain and a sliding panel, the actuation of these mobile elements by means of separate motor members becomes

  problematic on all of these aspects.

  In this context, the invention aims precisely to propose a device capable of overcoming these difficulties, and of meeting all of the existing needs. To this end, the device of the invention, moreover conforms to the generic definition given by the preamble above, is essentially characterized in that the curtain passes from its concealment configuration to its disengagement configuration during a first opening phase in which the panel remains in the closed position, in that the panel passes from its closed position to its open position during a second opening phase in which the curtain remains in its release configuration, in that the actuation means comprise a single motor and two pairs of drive points selectively moved simultaneously by the motor in the same direction in the direction of movement, in that the curtain is biased at the winding on the drum by an elastic return force, and in that two drive points, assigned to the actuation of the curtain, maintain the drawbar at the e against the elastic restoring force during the first opening phase, and emerge from the drawbar at the start of the second opening phase, during which two other points

  drive the panel.

  In its preferred embodiment, the device of the invention is designed so that the drum is arranged on a transverse edge of the opening which is perpendicular to the direction of movement and which constitutes for the opening a trailing edge in the direction of opening, that the points of the two pairs of drive points are carried by cables driven by the motor, that each pair of drive points comprises a first drive point assigned to the actuation of the curtain and a second drive point assigned to actuating the panel, and that the points of the first and second pairs of drive points are selectively moved simultaneously, in the same direction and in the same direction, along the first and corresponding second longitudinal edges corresponding to the opening, opposite one to

  each other and parallel to the direction of travel.

  It is also advantageous to provide that the second drive point of each pair of drive points is secured to a carriage, movable along the corresponding longitudinal edge of the opening, and supporting a link rocking about an axis of rotation, that the link has, at a distance from its articulation axis, an attachment relief and a control stud guided in sliding in a groove forming a ramp of a guide rail disposed on the corresponding longitudinal edge, that the groove forming a ramp prints on the nipple which slides therein in the opening direction, and for a transition position adopted by each second drive point between the first and second phases, a movement transverse to the direction of movement causing a tilting of the link in a first direction of rotation, and that the link, by its tilting, releases a lock selectively holding the panel in the closed position and engages its rel attachment ief in a complementary attachment relief secured to the panel, this panel then being secured to this second drive point in translation along the direction of

displacement.

  The complementary attachment relief may for example belong to a connecting arm secured to the

panel in translation.

  In a first possible variant of implementation, the device of the invention comprises a pair of cables driven by the same motor pinion, each cable

  carrying one of the pairs of training points.

  However, this device can also comprise two pairs of cables respectively disposed on the first and second longitudinal edges of the opening, in which case each cable carries one of the drive points, two cables of two different pairs of cables being moved by the same motor pinion, and the other two cables being

  moved by at least one other follower gear.

  Whatever the variant considered, at least one of the training points can be constituted by

one end of a cable.

  The device of the invention may also usefully comprise, for each cable, a guide slide in which this cable is slidably engaged and which radially surrounds the cable at an angle greater than 180 degrees, each cable itself comprising a helical winding with contiguous turns and having a selective rigidity which allows it to both bend and

transmit a thrust.

  The device of the invention is particularly advantageous in the case where the panel is

transparent or translucent.

  As previously announced, the invention relates generally (Figures 1a to 1c) a device for configuring the roof 1 of a motor vehicle, this device comprising an opening 100 cut out in the roof 1, a movable curtain 2, a panel sliding 3, and means 4 (Figures 2a to 2c) for actuating the

curtain and panel.

  The curtain 2 is designed to wind at will on a drum 21, which is fixed relative to the pavilion 1, this curtain being bordered by a parallel draw bar 22

drum 21.

  The curtain 1 can thus adopt, by displacement of the drawbar 22 in a direction of displacement D, a concealment configuration in which it is unwound from the drum 21 and covers the opening 100 (FIG. 1a), a release configuration in which it is wound around the drum 21 and releases the opening 100 (Figures 1b and 1c), or any

intermediate configuration.

  The passage from the concealment configuration to the release configuration is obtained by displacement of the drawbar 22 in the direction of displacement D and in the direction of opening SO, the passage in the opposite direction being obtained by displacement of the bar

  tension 22 in the closing direction Sl.

  As for the panel 3, it is slidably mounted relative to the roof 1 so as to be able to adopt at will, by sliding in the direction of movement D in the opening direction SQ or in the closing direction Si, a closed position in which it closes the opening 100 (Figures la and lb), an open position in which it releases the opening 100

  (figure lc), or any intermediate position.

  According to a first aspect of the invention, the opening of the curtain and that of the panel are offset with respect to each other, the invention preferably applying to the case where the panel 3 is transparent

or translucent.

  More specifically, the curtain 2 passes (Figures 2a to 2c) from its concealment configuration to its release configuration during a first opening phase (Dl in which the panel 3 remains in the closed position, while the panel 3 passes from its closed position to its open position during a second opening phase <F2 in which the curtain 2

  stays in its release configuration.

  To do this, the actuation means 4 comprise a single motor 40 and four drive points, denoted El1, E12, E21, and E22 which, on command, are simultaneously moved by the motor 40 in the same direction in the direction displacement D, these drive points being arranged in two pairs

noted El and E2.

  On the other hand, the drum 21 of the curtain 2 is connected to the roof 1 by a spring (not shown), so that the curtain 2 is urged to wind on the drum

  21 by an elastic restoring force.

  The two drive points Ell and E21, which are assigned to the actuation of the curtain 2, and which have the function of keeping the drawbar 22 against the elastic restoring force during the first opening phase (Dl, can thus free themselves from this drawbar 22 at the start of the second opening phase <F2 and continue their course for

all this second phase <F2.

  The two other drive points E12 and E22, which are assigned to the actuation of the panel 3, operate an unlocking of this panel at the start of the second opening phase cD2 and drive it in the direction

  SQ opening throughout this second phase.

  As shown in Figure lc, the drum 21 is disposed on the transverse edge 10 of the opening 100 which is perpendicular to the direction of movement D and which constitutes for this opening 100 a trailing edge

in the direction of opening SQ.

  Furthermore, as shown in Figures 2a to 2c, the drive points Ell, E12, E21, and E22 are carried by cables, such as Cll, C12, C21, and C22, driven by the motor 40, each point drive being for example formed by the end of a cable, or arranged

  in the immediate vicinity of such an end.

  Considering that the training points are arranged in pairs E1 and E2 in such a way that each pair comprises a first training point, such as Ell or E21, which is assigned to the actuation of the curtain 2, and a second point drive, such as E12 or E22, which is assigned to actuating the panel 3, FIGS. 2a to 2c show that the pairs El and E2 are arranged along corresponding longitudinal edges 11 and 12 of the opening 100, that is to say along the first and second respective longitudinal edges of the opening which are opposite to each other and parallel to the direction of movement D. Under these conditions, not only the drive points Ell and E12 of the first pair El are always moved together, on command, along the first longitudinal edge 11 of the opening, but when such a displacement is carried out, the drive points E21 and E22 of the second pair E2 themselves are always displaced in fa simultaneous lesson, in the same direction and in the same direction, along the second

  longitudinal edge 12 of opening 100.

  FIG. 2a illustrates a first alternative embodiment, in which the device comprises only a single pair of cables, denoted Cl. In this case, the cables C11 and C12 of this unique pair Cl can be driven by the same motor pinion 43 , and each of these cables Cîl and C12 carries one of the pairs

El or E2 of training points.

  FIGS. 2b and 2c illustrate two other alternative embodiments, in which the device comprises two pairs of cables, denoted Cl and C2 and respectively arranged on the longitudinal edges 11

and 12 of the opening 100.

  In this case, each of the cables, namely C11, C12, C21, and C22 carries one of the drive points Ell, E12, E21, and E22, and two cables belonging to two different pairs of cables are driven by a same motor pinion 43, while the other two cables are driven by one or more other pinions, which fill the

follower gear function 44.

  In the case of the second variant illustrated in FIG. 2b, the cables C12 and C21 belonging respectively to the pairs Cl and C2 are driven by the driving pinion 43, while the cable C11 is m by a follower pinion 44 which copies it into the reversing the movement of the cable C21, and that the cable C22 is m by another follower pinion 44 which copies by reversing the movement of the

cable C12.

  In the case of the third variant illustrated in FIG. 2c, the cables C12 and C22 belonging respectively to the pairs Cl and C2 are driven by the motor pinion 43 directly linked to the motor 40, while the cables Cil and C21 are moved by a pinion follower 44 who

  is connected to the axis of the motor pinion 43.

  The various bodies involved in the actuation of the curtain 2 and of the panel 3 are detailed in FIGS. 3 to 10C, which illustrate the device

  with the cable arrangement of Figure 2a.

  FIG. 3 represents only a subset of the device of the invention, observed from the side of the longitudinal edge 11 of the opening 100, and in the same state

than in Figures la and 2a.

  This figure makes it possible in particular to recognize the second drive point E12 of the cable C12, the first drive point Ell of the cable Cil, and the bar of

curtain 22 pull.

  Figure 3 also shows a link arm 6

  which is integral with the panel 3 in translation.

  In other words, the link arm 6 is fixed relative to the opening 100 in the first phase (Dl of opening and moves in the direction SO during the second phase t'2 of opening, in being guided by a

guide carriage 60.

  As shown in Figure 3, the link arm 6 practically materializes the edge 11 of the opening 100, the corresponding longitudinal edge of the curtain 2, and the corresponding longitudinal edge of the

panel 3.

  Throughout the first opening phase (D (Figure 5), the training points Ell and E12 are

  move together in the SW direction.

  During this entire phase, the drawbar 22, pulled by the curtain 2 (not shown in FIG. 5), itself elastically stressed when wound on the drum 21, is applied by its guide carriage 220 on the point Ell as formed by the inner end of the cable Cll, the drive point E12 moving simultaneously along the link arm 6. As shown in Figure 3 and Figures 5 to 7 with this drive point E12 , each drive point assigned to the actuation of the panel 3, that is to say each of the drive points E12 and E22, is integral with a carriage 41 mounted to slide along the corresponding longitudinal edge of the opening 100, i.e. from edge 11 for point E12, and from edge 12

for point E22.

  The carriage 41 supports a link 42 which is pivotally mounted about an axis of rotation Y and which has, at a distance from its axis of articulation Y, a lateral cutout 420 forming a hooking relief, and

a control pin 421.

  The control pin 421 points towards the outside of the opening 100 and is slidably engaged in a groove 50 of a guide rail 5 (FIGS. 9a and 9b) disposed on the corresponding longitudinal edge, 11 or 12,

of the opening 100.

  As best shown in Figure 4, which shows the rail 5 both on an enlarged scale and only partially for the sake of clarity, the groove 50 in fact comprises an upper track 50a and a track

  lower 50b between which it forms a ramp 501.

  As FIG. 4 also suggests, the ramp 501 is arranged in a transition zone between the

opening phases (Dl and D2.

  When the stud 421, by sliding in the upper track 50a of the groove 50 in the direction of opening SO, reaches the ramp 501, it undergoes a downward movement, that is to say a movement transverse to the direction of displacement D. The pin 421 then causes the tilting of the rod 42 around its axis Y in a direction of rotation

Ri (Figure 8).

  As shown in particular in Figure 6, the rod 42 has, in addition to its stud 421 and its cut

  lateral 420, an unlocking nose 422.

  Furthermore, the connecting arm 6, which is integral with the panel 3 in translation, has a latch 61 and a lug 62 forming a hooking relief

  complementary to the lateral cutout 420.

  The lock 61, which is pivotally mounted on the arm 6 around an axis Y ', is provided with a bolt 610 and a fork 611, this fork being turned towards the nose 422

of the link 42.

  The latch 61 is elastically biased in rotation about its axis Y 'in a direction for which the bolt 611 engages in a keeper 101 of the roof 1 (FIG. 10a) and thus keeps both the arm 6 and the panel 3 fixed compared to opening 100 during the entire first

phase (D1 opening.

  The ramp 501 is arranged so that, when the stud 421 switches the link 42 in the direction of rotation R1, the nose 422 of this link engages in the fork 611 of the lock 61, and its lateral cut 420

engages on lug 62.

  The nose 422 of the connecting rod thus switches the latch 61, the bolt 610 of which emerges from the keeper 101, allowing the sliding of the link arm 6 and the

panel 3.

  Simultaneously, the engagement of the lateral cutout 420 on the lug 62 makes the link arm 6 and the panel 3 integral in translation with the drive point E12 along the direction D, the opening phase () 2 continuing with the movement of all the drive points in the direction

opening hours SO.

  However, as the curtain 2 is then wound on the drum 21, the drive points E11 (FIG. 7) and

  E21 are released from the drawbar 22.

  The panel returns to the closed position symmetrically by translating the drive points in the direction S 1, the arm 6 being driven by the drive point E12 and its counterpart E22 due to the engagement of the lateral cutout 420

  of each link on the corresponding pin 62.

  As soon as the nose 422 of each link releases the corresponding lock 61, the bolt 610 of the latter comes

  fit into the corresponding keeper 101.

  If the actuation continues in the closing direction S1, the drive points E11 and E21 push back the draw bar 22 and close the curtain 2

by unwinding from the drum 21.

  Insofar as the cables must have a selective rigidity allowing them both to bend and to transmit a thrust, they preferably include a helical winding with contiguous turns

  surrounding a metallic central core.

  In addition, as shown in Figures 9a to 9c, the rail 5 disposed on each of the edges 11 and 12 of the opening is preferably provided with guide rails such as 511 and 512, in each of which

  one of the cables is slidably engaged.

  Finally, each slide such as 511 and 512 radially surrounds the cable which slides therein at an angle greater than 180 degrees but less than 360 degrees, so that this cable can entrain a part which extends at least partially out of this slide, as is the case for the carriage 41 which encloses the end E12 of the cable C12 and which is partially inserted in the slide 512, and as is also the case for the guide carriage 220 of the drawbar 22, which is engaged in the slide 511 to be retained in translation by the end Ell of the cable Cil.
