The two phases are carried out by a single motor with two pairs of drive points and cables, with the panel being tilted as it interacts with guide rails along the sides of the roof opening.

Description

VEHICLE PAVILION CONFIGURATION DEVICE

  AUTOMOTIVE, COMPRISING A CURTAIN AND A TILTING 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 tilting 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 adopting selectively, by displacement of the draw bar in a direction of movement and in a first direction or in a second direction corresponding to the winding of the curtain, a blackout configuration 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 panel tilting selectively adopting a closed position in which it is applied to the opening and closing, and a pos half-open ition in which it is

away from the opening.

  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 tilting 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 half-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, the drive points of each pair being selectively moved simultaneously by the motor in opposite directions along the direction displacement, in that the curtain is urged on the drum on the drum by an elastic return force, and in that two drive points, assigned to the action curtain, hold the drawbar against the elastic restoring force during the first opening phase, and disengage from the drawbar at the start of the second opening phase, during which two other training points move the

  panel from its closed position.

  In its preferred embodiment, the device of the invention is designed so that the drum is disposed on a first transverse edge of the opening which is perpendicular to the direction of movement and which constitutes for the opening a trailing edge in the second direction, that an active transverse edge of the panel, distant from the first transverse edge of the opening, is, in the partially open position of the panel, separated from a second transverse edge of the opening opposite to the first transverse edge , that the points of the two pairs of drive points are carried by two 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 point of drive assigned to the actuation of the panel, and that the points of the first and second pairs of drive points are selectively displaced symmetrically along the first and second bo corresponding respective longitudinal rds of the opening, opposite one another and parallel to the direction of

displacement.

  It is also advantageous to provide that this device comprises, on each of the longitudinal edges of the opening, a parting mechanism selectively moving the active transverse edge of the panel, as the second drive point of each pair of drive points either secured to a driving carriage, movable along the corresponding longitudinal edge of the opening, and the half-opening mechanism operates a locking of the panel relative to the roof outside the second opening phase, and a conversion of a translational movement of the driving carriage along the direction of movement in a tilting movement of the panel at

  during the second opening phase.

  To do this, it is possible to provide that the drive carriage carries a drive finger, that the panel opening mechanism includes a driven carriage, a tilting lever, and a linkage, that the linkage has a first end articulated around an axis fixed relative to the roof, a second end linked to the panel on the side of its active transverse edge, and a ramp, that the rocking lever has a first end articulated around an axis fixed relative to the carriage driven, a second end facing the drive carriage, a lug disposed between its first and second ends and cooperating with the ramp of the crankshaft, a bolt formed on its second end and cooperating selectively with a keeper fixed relative to the bell , and a front light forming a cam and cooperating selectively with the finger, that the movement of the drive carriage in the first direction beyond the first phase of opening causes engagement of the finger in the light and a tilting of the rocking lever releasing the bolt from the strike and trapping the finger in the light, and that the displacement of the drive carriage in the first direction during the second opening phase causes a displacement in the same direction of the driven carriage and a displacement of the lug on the ramp, which results in a rotation of the crankshaft around the fixed axis and

  the correlated opening of the panel.

  In an advantageous embodiment of the invention, at least one of the drive points can be formed by one end of one of the cables. Furthermore, the device of the invention may, on each of the longitudinal edges of the opening, comprise a guide rail supporting the ajar mechanism and in which the carriage

  is mounted sliding.

  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 tilting 3, and means 4 (Figures 2a to 2c) for actuating the curtain and the 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 therefore obtained by displacement of the drawbar 22 in the direction of displacement D in the winding direction S2, the passage in the opposite direction being obtained by displacement of the bar tension 22 in the direction of unwinding S1. The panel 3 is in turn mounted tilting relative to the roof 1 to be able to adopt at will a closed position in which it is applied to the opening 100 and the shutter (Figures la and lb), and a partially open position maximum in which its transverse edge 302, for example its rear edge for the forward direction S2 of the vehicle, deviates from the corresponding transverse edge 13 of the opening 100 (FIG. 1c). Between its maximum closed and half-open positions, the panel adopts a continuum of intermediate half-open positions that can

  be stable or simply transient.

  According to a first aspect of the invention, the opening of the curtain and the half-opening 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 precisely, the curtain 2 changes from its concealment configuration to its release configuration during a first opening phase (D1 (FIGS. 2a to 2b) in which the panel 3 remains in the closed position, this first phase corresponding to the movement represented by the transition from the configuration of FIG. 2a to the configuration of the

Figure 2b.

  Then, the panel 3 passes from its closed position to its stable half-open position, single or maximum, during a second opening phase (D2 in which the curtain 2 remains in its release configuration, this second phase corresponding to the movement represented by the passage of the configuration

  from Figure 2b to the configuration of Figure 2c.

  To do this, the actuation means 4 comprise a single motor 40 and four drive points, denoted Ell, E12, E21, and E22, and arranged

in two pairs denoted El and E2.

  The drive points of each pair are, on command, moved by the motor 40 in the opposite direction, along the direction of movement D. 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, have the sole function, before the first opening phase (Dl and during this, of maintaining the drawbar 22 against the elastic restoring force which brings it back

towards the drum 21.

  These training points Ell and E21 can therefore freely disengage from the drawbar 22 from the start of the second opening phase D2, and continue

  their course throughout this second phase @ 2.

  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 'D2 and drive it towards its maximum half-open position. throughout this second phase. As shown in Figures la to lc, the drum 21 is disposed on the first 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 winding S2 of the curtain 2. The active transverse edge 302 of the panel, that is to say the edge by which the panel 3 deviates from the opening in its half-open position, is distant from this first transverse edge 10, therefore distant

drum 21.

  Furthermore, as shown in Figures 2a to 2c, the drive points Ell, E12, E21, and E22 are carried by two cables C1 and C2 driven by the motor 40 through a motor pinion 400, each drive point being for example formed by the end of a cable, or

  disposed in the immediate vicinity of such an end.

  Considering that the pairs E1 and E2 of training points are formed so that each includes a first training point, such as Ell or E21, which is assigned to the actuation of the curtain 2, and a second point of drive, such as E12 or E22, which is assigned to the actuation of the panel 3, FIGS. 2a to 2c show that the pairs E1 and E2 are arranged along corresponding longitudinal edges 11 and 12 of the opening 100, c ' 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, the drive points of the two pairs El and E2 are moved, on command, symmetrically along the longitudinal edges

  respective correspondents 11 and 12 of the opening 100.

  Furthermore, the device comprises, on each of the longitudinal edges 11 and 12 of the opening 100, a half-opening mechanism 30 intended to exploit the movement of the drive points E12 and E22 for

  move the active transverse edge 302 of the panel 3.

  More specifically, this ajar mechanism 30 has the function of locking the panel 3 relative to the roof 1 outside the second opening phase (D2, and of converting, during the second opening phase, the movement of translation effected by the corresponding drive point E12 or E22, along the direction of movement D, in a tilting movement of the panel 3. To do this, each of the second drive points E12 and E22 is integral with '' a driving carriage 41, which is slidably mounted in a guide rail 5, along the corresponding longitudinal edge 11 or 12 of the opening, and which carries a finger

training 42.

  The half-opening mechanism 30 of the panel 3 is itself supported by the guide rail 5 and essentially comprises a driven carriage 31, a lever

tilting 32, and a linkage 33.

  As best shown in Figures 4a and 4b, the linkage 33 has a ramp 333 disposed between two ends 331 and 332 of this linkage, the end 331 distant from the opening 100 being articulated about an axis Y0 supported by the rail 5 and fixed relative to the pavilion 1, and the end 332 adjacent to the opening being linked to the panel 3 on the side of its edge

transverse active 302.

  The tilting lever 32 has a lug 323 disposed between the ends 321 and 322 of this lever,

  and cooperating with the ramp 333 of the connecting rod assembly 33.

  The end 321 of the lever which is distant from the opening 100 is articulated around an axis Y1 carried

  by the driven carriage 31 and fixed relative to it.

  The end 322 of the lever which is adjacent to the opening 100 faces the drive carriage 41 and has a bolt 324 and a light

frontal 325.

  The bolt 324 is intended to cooperate with a keeper 51 formed in the rail 5 and therefore fixed relative to the roof 1. The front light 325 fulfills the role of a cam cooperating with the finger 42 of the drive carriage 41 during the second opening phase, as in figures 4

and 5 allow us to understand it.

  In fact, when the drive carriage 41 is moved in the direction Sl beyond the position it occupies at the end of the first opening phase '1, and which is illustrated in FIG. 4, the finger 42 engages in the light 325 and slides on a rounded edge of

it.

  The translation of the drive carriage 41 in the slot 325 thus causes the lever 32, the end 322 of which departs from the

rail 5.

  The bolt 324, which is carried by this end 322, emerges from the keeper 51 and comes to bear against a web 52 of the rail 5, parallel to the direction of movement D. Simultaneously, the bottom of the light 325, which is shaped as buttonhole open, comes in contact with

finger 42 (Figure 4b).

  Insofar as the finger 42 is guided in translation, and the web 52 of the rail 5 blocks the rotation of the lever 32 in the opposite direction to the tilting which it has just undergone, the finger 42 is then

trapped in light 325.

  Any subsequent movement of the drive carriage 41 in the direction S 1 causes an equivalent movement, and in the same direction Si, of the driven carriage 31 and the axis

Yl of the tilting lever 32.

  The lug 323 carried by this rocking lever therefore moves on the ramp 333, imparting to the crankshaft 33 a rotation about the fixed axis YO and spreading the edge 302

  of the panel 3 of the corresponding edge 13 of the opening 100.

  The return of the panel to the closed position and of the curtain in its blackout configuration is carried out by the sequence of operations exactly opposite to that which

has just been described.

  As shown in Figure 3, the rail 5 disposed on each of the edges 11 and 12 of the opening is preferably provided with guide rails, such as 511, in each of which one of the cables, such as

Cl, is engaged in sliding.

  Finally, each slide such as 511 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 c is the case for the carriage 41 which the

cable Cl.
