Description

The present invention relates to a support device for a vehicle of a functional element that can be deployed, the device comprising at least two lateral walls that are substantially parallel and that delimit a volume between them. internal, and a support member for carrying the functional element, said support member being movable in translation along the side walls and in rotation about an axis substantially perpendicular to the side walls between a retracted position, in which the functional element is intended to extend into the internal volume, and an extended position, in which the functional element is intended to protrude from the internal volume, the support element being displaced between the retracted position and the position deployed via at least one axis integral with the suppo element rt and movable in at least a first guide track extending on one of the side walls, said axis being integral with an actuating device arranged to move said axis in said guide track. The present invention also relates to a display system comprising such a support device. The invention applies for example to a display system for displaying information for driving assistance in a vehicle or a support device of a portable terminal. It is known to provide a display system in the vicinity of a vehicle driver to provide various information on the state of the vehicle, on an audio system, on the movement of the vehicle or other. Such a system is for example provided on the dashboard of the vehicle and comprises a screen intended to extend projecting from the surface of the dashboard so as to be visible by the driver, without it diverts the eyes of the road. For reasons of safety and aesthetics, the display device is intended to be movable between a retracted position, in which it extends in the dashboard and is invisible from the outside thereof, and a deployed position in which it is visible, as described above. To do this, the display device is secured to a support device integrated in the dashboard and adapted to move the display device between the retracted position and the deployed position in a suitable kinematic. Displacement is generally controlled by a motor arranged to move one or more links integral with the display device in slides or paths adapted to move the display device according to the desired kinematics.

The deployment of the display device is in a direction from upstream to downstream of the support device and the display device is downstream of this device when it is deployed. Thus, a force applied to this device directed from downstream to upstream is likely to cause the retraction of the display device or at least one displacement of this device to its retracted position. Or this force is likely to be applied by the user of the device itself when the device is intended to be controlled by its facade, as is the case for a touch screen for example. In this case, when the user presses on the device, it tends to move towards its retracted position and does not offer an impression of stability and robustness to the user, which reduces the quality perceived by the latter. this. One of the aims of the invention is to overcome this disadvantage by providing a reliable support device ensuring a robust locking of the device in its deployed position so that it is stable in this position.

To this end, the invention relates to a vehicle support device of the aforementioned type, characterized in that the first guide track comprises a first section and a second section, the first section extending substantially in the direction of deployment of the vehicle. support element between an upstream end, in which is the axis in the retracted position, and a transition point, in which is the axis in the vicinity of the deployed position, the second section being inclined relative to the first section and with respect to the deployment direction of the support member and extending between the transition point and a downstream end, in which the axis is in the deployed position. In the deployed position, the axis driving the movement of the support device is in the second section of the guide track which extends across the direction of deployment and retraction of the support device. Thus, if a user exerts a support going in the direction of retraction of the support, the axis is blocked in the second section and opposes a displacement of the support device. The deployed position is therefore stable, which increases the quality perceived by the user when he presses on the device. According to other characteristics of the support device according to the invention: the support element comprises a receiving surface of the functional element, said reception surface extending substantially in the direction of deployment of the element of support in the retracted position and in a plane substantially inclined with respect to this direction and projecting from the internal volume in the deployed position; - The second section of the first guide track extends in a direction substantially parallel to the receiving surface of the support member in the deployed position; the first guide track is formed by a slideway within which the axis is able to move; - The width of the slide decreases in the vicinity of the downstream end of the first guide track and becomes, at the downstream end, substantially equal to the diameter of the axis moving in said first track so as to block said axis in the deployed position, said downstream end forming a housing for stopping said axis; the axis secured to the support element is movable in two first guide tracks, each of said tracks respectively extending on one of the lateral walls, said first guide tracks being parallel to one another and presenting the same form; at least a portion of each of the first guide tracks extends at a first distance from the corresponding portion of the other first guide track, from the upstream end of said tracks to the vicinity of the downstream end of said tracks; said first distance being arranged to allow displacement of the axis in said first guide tracks, and at a second distance from each other at the downstream end, the second distance being smaller than the first distance and being arranged to remove the clearance between the axis and the sidewalls when the support member is in its deployed position; each first guide track comprises a rib projecting from said guide track towards the other guide track, and the axis comprises a roller adjacent to each of its ends and extending facing said rib, said ribs extending at a distance from each other greater than the distance separating the rollers from the axis, from the upstream end of the first guide tracks to the vicinity of the downstream end of said tracks, and extending to a distance from each other substantially equal to the distance separating the rollers from the axis at the downstream end of said first guide tracks; said support device further comprises two second guide tracks respectively extending on one of the lateral walls facing the first guide track, a shaft being integral with the support element, the ends of said shaft being respectively disposed on one of said second guide tracks, the displacement of the support member causing said ends of said shaft to move on said second guide tracks; the distance separating the second guide tracks is greater than the length of the shaft from the upstream end of said tracks to the vicinity of the downstream end of said tracks and is substantially equal to the length of the shaft at the downstream end so as to remove the clearance between the shaft and the side walls when the support member is in its extended position; - The downstream ends of the second guide tracks each comprise a stop housing, said housing having a width substantially equal to the diameter of the ends of the shaft so as to lock said shaft in the deployed position; - The stop housing of the second guide tracks is oriented in a direction substantially opposite to the direction in which is oriented the stop housing of the first guide track; the actuating device comprises a first arm secured at its upstream end to a shaft driven in rotation by a motor and articulated at its downstream end to a second arm, itself articulated at its downstream end to the integral axis of the support element, the downstream end of the second arm being close to the upstream end of the first arm in the retracted position and away from it during the passage to the deployed position due to the rotation of the shaft driven by the motor, so as to push the axis towards the downstream end of the first guide track during this movement; said support device comprises a flap movable between a closed position, in which it covers at least a part of the internal volume when the support element is in the retracted position, and an open position, in which it releases a passage towards the volume internal when the support member is in the deployed position.

Other aspects and advantages of the invention will appear on reading the description which follows, given by way of example and with reference to the appended drawings, in which: FIG. 1 is a diagrammatic perspective view of a display system according to the invention, the display device being in its extended position, FIG. 2 is a schematic perspective view of the display system of FIG. 1 from the rear, - FIG. 3 is a schematic representation of the support device used in the display system of FIGS. 1 and 2, without the support member, the support device being in a retracted position; 4 is a schematic representation of the device of FIG. 3 in an extended position, and - Figs. 5 and 6 are schematic side representations of one of the side walls of the support device when the support member is in the retracted position and in the extended position. With reference to Figs. 1 and 2, there is described a display system 1 comprising a display device 2 and a support device 4. Although the support device 4 is described in relation with the display system 1 according to the invention, it It is understood that this support device 4 could be adapted to support and move another type of functional element, such as a control device of an audio system or the like. The display device 2 may be of any suitable type, such as a navigation device or vehicle management screen or a portable terminal, such as a touchscreen telephone or tablet. The display device 2 can be fixedly attached to the support device 4 or removably attached thereto. The display device 2 comprises a display panel 6 suitable for generating and displaying images, coupled to a control electronics capable of generating control signals of the display panel 6 for displaying images on the display panel. this. The display panel 6 may be of the tactile type, making it possible to control the functions of the display device 2 or of the vehicle by touching the display panel 6. The support device 4 is adapted to support and move the device. display 2 or at least the display panel 6 thereof. The support device 4 is for example intended to be arranged in a vehicle dashboard or in another type of lining element. It may form an integral part of this packing element or be attached thereto. Alternatively, the support device 4 can form an independent housing. The support device 4 comprises two side walls 10 substantially parallel to one another and spaced from each other, for example according to the width of the display panel 6. The side walls 10 extend for example substantially in the front-rear direction of the vehicle in which the support device 4 is installed. In the rest of the description, the direction in which the side walls 10 extend from upstream to downstream will be called the deployment direction. The direction opposite to the direction of deployment is called the direction of retraction and the direction perpendicular to the directions of deployment and retraction and extending according to the height of the side walls 10 is called elevation direction. The terms "upper" and "lower" are defined with respect to this elevation direction. The space extending between the two side walls 10 forms an internal volume 12 of the support device 4 inside which the display device 2 is intended to extend in the retracted position, as will be described later. The side walls 10 extend mainly perpendicularly to the display panel 6. According to the embodiment shown in the figures, they are connected to one another by a bottom wall 14 closing at least a portion of the internal volume. 12 and extending under and between the side walls 10. At least one of the side walls 10 comprises, on its side extending on the side of the internal volume 12, a first guide track 16 extending along the side wall 10 in the vicinity of an upper edge of this side wall 10, that is to say on the side of the side wall 10 opposite the bottom wall 14. The first guide track 16 extends substantially in the direction of deployment between an upstream end 18 and a downstream end 20. The first guide track 16 is for example formed by a slide projecting from the side wall 10 to the other side wall 10. Such a slide comprises two walls 2 2 parallel to each other, offset in height on the side wall 10 and extending substantially perpendicular to the side wall so as to define between them the path of the first guide track 16. The walls 22 of the slideway meet at the downstream end 20 so as to form a stop housing 24, whose concavity is turned upwardly and upstream, as more particularly visible in FIGS. 4 and 5. According to the embodiment shown in the figures, the upper wall 22 of the slideway further comprises a rib 26 projecting from the upper wall 22 in the extension thereof. The first guide track 16 comprises a first section 28 extending from the upstream end 18 to a transition point 30 disposed near the downstream end 20 and a second section 32 extending from the transition point 30 downstream end 20.

The first section 28 extends substantially in the direction of deployment. The first section 28 has for example a substantially arcuate shape, for example of substantially constant radius of curvature. The arcuate shape of the first section 28 forms a concavity facing upwards. The second section 32 is inclined relative to the first section 28 and the deployment direction. By inclined, it is meant that the second section 32 extends in a direction different from the direction of the first section so that a bend is formed at the right of the transition point 30 between the first section 28 and the second section 32. In particular, the term inclined means that the second section 32 forms an angle greater than or equal to 45 ° with the first section 28. As shown in FIGS. 2 to 6, the second section 32 is oriented towards the bottom wall 14, that is to say that the second section 32 extends from the transition point 30 to the bottom wall 14. According to the method of embodiment shown in the figures, the support device 4 comprises two first guide tracks 16 respectively provided on each of the side walls 10. The first guide tracks 16 are substantially symmetrical to one another relative to the plane parallel to the walls Lateral projections 10 extend in the center of the internal volume 12. Therefore, the first guide tracks 16 have the same shape and extend substantially parallel to each other facing each other. The distance separating the two first guide tracks 16 is substantially constant from the upstream end 18 to the vicinity of the downstream end 20 and is reduced to the right of the downstream end 20 in the stop housing 24. According to a embodiment, the reduction of the distance separating the two first guide tracks 16 is performed in line with the ribs 26, that is to say that the thickness of the ribs 26 increases at the downstream end 20 of the first tracks of 16. Thus, the ribs 26 extend at a first distance from each other from the upstream end 18 of the first guide tracks 16 to the vicinity of the downstream end 20 and at a second distance. one of the other at the downstream end 20, the second distance being less than the first distance. Alternatively, this reduction of the distance can be done by bringing the bottom of the slides forming the first guide tracks 16 closer to their downstream end 20, for example by bringing the side walls 10 closer to each other in the right direction. downstream ends 20 of the first guide tracks 16. Each side wall 10 further comprises, on its side extending on the side of the internal volume 12, a second guide track 34 extending along the side wall 10 in the vicinity a lower edge thereof, that is to say near the bottom wall 14 of the support device 4, facing the first guide track 16. The second guide track 34 extends substantially from one end of the longitudinal wall 10 to the other in the direction of deployment, between an upstream end 36 and a downstream end 38. According to the embodiment shown in the figures, the upstream end 36 of the second udder The guide 34 is disposed substantially in line with the upstream end 18 of the first guide track 16, while the downstream end 38 of the second guide track 34 extends downstream of the downstream end 20 of the guide track. first guide track 16, that is to say that these downstream end 20 and 38 are offset relative to each other in the direction of deployment. According to the embodiment shown in the figures, the downstream ends 20 and 38 are further aligned in the direction of deployment. That is, they are arranged substantially on the same straight line extending in the direction of deployment. Each second guide track 34 comprises a toothed track 40, for example of the rack type, as shown in FIGS. 3 to 6. By notched track 40, is meant a track comprising a plurality of teeth 41 adjacent to each other, distributed over the entire length of the track and extending substantially perpendicular to the direction of the length of the track, as shown more particularly in FIGS. 5 and 6. According to the embodiment shown in these figures, the teeth extend upwardly from the side walls 10, that is to say away from the bottom wall 14. The toothed track 40 presents an arcuate shape, having for example a substantially constant radius of curvature and the concavity is turned upwards, that is to say in the direction in which the teeth extend 41. The arcuate shape of the toothed track 40 is substantially parallel to the shape of the first section 28 of the first guide track 16. According to one embodiment, the second guide track 34 has a radius of curvature substantially equal to that of the first section 28 of the first guide track 16 At its downstream end 38, each second guide track 34 comprises a recess comprising a portion extending facing the toothed portion of the downstream end 38 and forming therewith a stop housing 42, as will be describes u Ater. The concavity of the housing 42 is turned towards the upstream end 28 of the second guide track and towards the bottom wall 14, as shown in FIGS. Set 6. Thus, the concavity of the stop housing 42 is rotated in a direction opposite to that towards which is turned the stop housing 24 of the first guide track 16. Each second guide track 34 further comprises a groove 43 adjacent to the toothed track 40 and forming a recess in the side wall 10 so as to extend the toothed track 40 in the direction perpendicular to the side wall 10. The groove 43 is toothless and has substantially the same shape as the track notched, as shown in Figs. 5 to 6. The second guide tracks 34 are substantially symmetrical to one another with respect to a plane parallel to the side walls 10 extending at the center of the internal volume 12. Consequently, the second guide tracks 34 have the same shape and extend substantially parallel to each other facing each other. The distance separating the two second guide tracks 34 is substantially constant from the upstream end 36 to the vicinity of the downstream end 38 and is reduced to the right of the downstream end 38 in the stop housing 42. embodiment, the reduction of the distance separating the two first guide tracks is performed at the right of the groove 43, that is to say that the bottoms of said grooves 43 are brought closer to each other at the downstream end 38 of the second guide tracks 34. According to a particular embodiment, this reduction in the distance separating the bottoms of the grooves 43 to the downstream end 38 of the second guide tracks 34 is achieved by a protruding rib from each bottom of the throat to the other gorge. The support device 4 further comprises a support member 44 movable between the side walls 10 by means of the first and second guide tracks 16 and 34. The support member 44, shown only in FIGS. 1 and 2, comprises a receiving surface 46, intended to receive a functional element, that is to say at least the display panel 6 of the display device 2 in the context of the display system described above, and a shoulder 48 projecting from the receiving surface 46, for example substantially perpendicular to it. The shoulder 48 extends at a lower end of the receiving surface and the side of the receiving surface 46 opposite the side which is intended to receive the functional element. The shoulder 48 comprises a bonded end 50 on the side of the receiving surface 46 connected to this surface 46 and a free end 52 on the opposite side of the bonded end 50. The receiving surface 46 and the shoulder 48 extend in width substantially from one side wall 10 to the other and are arranged between these side walls.

In the vicinity of the free end 52 of the shoulder 48, the support member 44 comprises an axis 54 secured to the support member 44 and at least one of the ends 56 is disposed in the first guide track 16. The axis 54 extends substantially perpendicular to the side walls 10, that is to say along an axis A substantially perpendicular to the direction of deployment. According to the embodiment shown in the figures, the two ends 56 of the axis 54 are each disposed in one of the first guide tracks 16 respectively. The ends 56 of the axis 54 are for example formed by pins introduced into the slides forming the first guide tracks 16, that is to say between the walls 22 of these slides, as more particularly shown in FIGS. 5 and 6. The axis 54 further carries two rollers 58 adjacent respectively to each end 56 of the axis 54 and whose diameter is greater than the distance between the walls 22 of the slideways so that each roller 58 extends facing the rib 26 provided on the upper wall 22 of each slide. From the upstream end 18 in the vicinity of the downstream end 20 of the first guide tracks 16, the first distance separating the ribs 26 from the first guide tracks 16 is slightly greater than the distance separating the faces of the rollers 58 extending in view of these ribs 26, so that the axis 54 can move in the first guide tracks, for example by sliding between the walls 22 of the slides. In the vicinity of the downstream ends 20 of the first guide tracks 16, the second distance separating the ribs 26 is reduced to become substantially equal to the distance separating the faces of the rollers 58 extending opposite these ribs 26 at the ends. downstream 20. Thus, when the ends 56 of the axis 54 are in the stop housing 24 of the first guide tracks 16, the rollers 58 bear against the ribs 26 and there is no play according to the direction perpendicular to the side walls 10 between the rollers 58 and the first guide tracks 16.

The diameter of the ends 56 of the axis 54 is slightly smaller than the width of the slideway of the upstream end 18 of the latter in the vicinity of the downstream end 20. At the downstream end 20, the width of the slides decreases to become substantially equal to the diameter of the ends 56 of the axis 54. Thus, when the ends 56 of the axis 54 are in the stop housing 24 of the first guide tracks 16, the ends 56 of the axis 54 are locked in the direction of elevation by the walls 22 of the slide. There is therefore no clearance in the direction of elevation of the side walls 10 between the ends 56 of the axis 54 and the slides of the first guide tracks 16 when the ends 56 of the axis 54 are in the lock housing 24.

In the vicinity of the bonded end 50 of the shoulder 48, two gear elements 60 are rotatably mounted on the support member 44 and are each respectively disposed on one of the second guide tracks 34. The guide elements 60 are movable in rotation about the same axis B substantially perpendicular to the side walls 10, that is to say substantially parallel to the axis A which extends the axis 54. According to the embodiment shown on Figs. 3 and 4, the gear elements 60 are mounted on the end portions of a shaft 62 extending from one side wall 10 to the other and rotatably mounted about the axis B with respect to the Support element 44. The shaft 62 thus passes through the support element 44 in the vicinity of its bonded end and is rotationally integral with the two gear elements 60, that is to say that the rotation of the shaft 62 causes the synchronized rotation about the same axis B of the two gear elements 60. Alternatively, each gear element is mounted directly in rotation on the support member 44 independently of the other gear element. In this case, the axis of rotation of each gear element 60 coincides with the axis of rotation of the other gear element 60. Each gear element 60 is formed by a toothed wheel, or pinion, whose teeth 64 extend radially about the axis of rotation B and are adapted to mesh with the teeth 41 of the toothed track 40. Thus, the pitch of the successive teeth 64 of each gear element 60 is equal to the pitch successive teeth 41 of each toothed track 40. Each gear member 60 is extended by a substantially cylindrical pin 65 (Fig 5), free of teeth, and extending about the axis B. When the gear is disposed on the toothed track 40, the pin 65 extends into the groove 43, as more particularly visible in FIGS. 5 and 6. The diameter of the pin 65 is slightly less than the width of the groove 43 of the upstream end thereof in the vicinity of the downstream end 38. At the downstream end 38, the width of the groove 43 decreases to become substantially equal to the diameter of the pin 65. Similarly, at the downstream end 38 of the second guide tracks 34, the distance separating the bottom of the grooves 43 is substantially equal to the length of the shaft 62 along the axis B of the free end of a pin 65 at the free end of the other pin 65. Thus, when the gear elements 60 are in the stop housing 42 of the second track of 34, they are locked in this housing in the direction perpendicular to the side walls 10 and in the direction of elevation of the side walls 10 due to the adjustment of the dimensions of the grooves 43 and the distance between the grooves 43 to the dimensions of the pawns 65 and at the distance between pawns 65. There therefore has no clearance between the pins 65 and the grooves 43 in the direction of elevation and in the direction perpendicular to the side walls 10 at the downstream ends 38 of the second guide tracks 34. The axis 54 is able to move in the first guide tracks 16 under the action of a motorized actuating device. The actuating device comprises a motor 66 arranged to drive in rotation, about an axis C perpendicular to the side walls 10, a shaft 68 rotatably mounted on the side walls 10 and extending between these side walls 10. first arm 70 is connected to the shaft 68 by its upstream end 72 and is integral in rotation with this shaft 70. The first arm 70 is articulated, at its downstream end 74, to the upstream end 76 of a second arm 78 around an axis perpendicular to the side walls 10. The upstream end 80 of the second arm 78 is itself articulated to the axis 54 about the axis A perpendicular to the side walls 10 (Figure 3).

The support device 4 further comprises a flap 81 arranged to cover a portion of the internal volume 12 so as to hide the support device 4 in the retracted position. The portion of the internal volume 12 covered by the flap 81 extends for example opposite the downstream part of the side walls 10 and is delimited by an opening formed in a part intended to be visible from outside the packing element. in which the support device 4 is integrated and covering the internal volume 12. Thus, the opening may for example be formed in the coating of the packing element at the area in which the support surface 46 is intended to extend in the deployed position. The opening may be made directly in the lining of the lining element or may be formed in a cover intended to be integrated with the lining element. The flap 81 extends from one side wall 10 to the other and is mounted movable in translation relative to the side walls 10. To this end, the flap 81 comprises at its downstream end at least one pin 84 extending in protruding from the downstream end of the shutter 81 in a direction perpendicular to the side walls and arranged in a slideway 86 formed in one of the side walls 10. The shape of the slideway 86 defines the path of movement of the shutter 81. embodiment shown in Figures 1 to 4, the flap 81 comprises two pins 84 projecting from the flap on either side thereof and each disposed respectively in a slide 86 provided on each of the side walls.

The upstream end of the shutter 81 is articulated to a first connecting rod 88 rotatably mounted on one of the side walls 10 about an axis perpendicular to the side walls 10. The connecting rod 88 is further connected to a downstream end 89 of a control rod 90 extending in the direction of deployment. The upstream end 92 of the control rod 90 is articulated to a second connecting rod 94 rotatably mounted on the same side wall 10 as the first connecting rod 88 about an axis perpendicular to the side walls 10. A constraint element 96 is arranged around the axis of rotation of the second connecting rod 94 to constrain the second connecting rod 94 so that it exerts traction on the control rod 90 in a direction opposite to the direction of deployment. The second connecting rod 94 further comprises an actuating surface 98 adapted to be pushed by the first arm 70 against the force of stress exerted by the constraining element 96 on the second connecting rod 94.

The operation of the support device 4 described above will now be described in connection with FIGS. 3 to 6, in which part of the support device 4 has been removed for better understanding. In FIG. 3, the support device 4 has been shown in a retracted position of the support member 44. In this position, the support member 44 extends completely into the internal volume 12. The receiving surface 46 extends in particular opposite the bottom wall 14 and in the direction of deployment. The shoulder 48 extends substantially in the direction of elevation of the side walls 10 so that the ends 56 of the axis 54 are in the upstream ends 18 of the first guide tracks 16 and that the elements 60 are in the upstream ends 36 of the second guide tracks 34, as shown in FIG. 5. In this position, the downstream end 80 of the second arm 78 of the actuating device is brought closer to the upstream end 72 of the first arm 70 and the first arm 70 extends in a direction opposite to the direction of deployment of the downstream upstream. The first arm 70 also exerts pressure on the second link 94 by pressing on its actuating surface 98 so that the control rod 90 is pushed in the actuating direction and the pins 84 projecting from the downstream end of the shutter 81 are arranged in the downstream end of the slideways 86, as shown in FIG. 3. In this position, the flap 81 thus extends into the opening and masks the internal volume 12 of the support device 4. To move the support member 44 into its deployed position, the motor 66 is actuated so to cause a rotation of the shaft 68 in a first direction arranged to move the first arm 70 towards the direction of deployment by causing it to rotate about the axis C perpendicular to the side walls 10. During this movement, the first arm 70 exerts a thrust on the second arm 78 whose downstream end 80 deviates from the upstream end 72 of the first arm 70 and moves downstream in the direction of deployment, as shown in FIG. Fig. 4. The second arm 78 and pushes in the direction of deployment axis 54, whose ends 56 move in the first section 28 of the first guide tracks 16. The axis 54 secured to the support member 44 therefore causes a displacement thereof in the direction of deployment, which causes a translation and rotation displacement of the gear elements 60 on the second guide tracks 34 by the cooperation of the teeth 64 of the gear elements 60 with the teeth 41 of the toothed tracks 40, as shown in FIGS. 5 and 6.

Due to the arcuate shape of the first sections 28 of the first guide tracks 16 and the arcuate shape of the second guide tracks 34, the displacement of the support element 44 is in translation in the direction of deployment downstream. and in rotation about an axis substantially perpendicular to the side walls 10 arranged to raise the receiving surface 46 upwardly of the internal volume 12, which causes a corresponding tilting of the shoulder 48.

At the same time, immediately after the beginning of the movement of the first arm 70 in rotation, the latter disengages from the actuating surface 98 of the second connecting rod 94 and stops exerting a bearing on it. The constraint element 96 then causes the rotation of the second connecting rod 94 which pulls the control rod 90 in a direction opposite to the direction of deployment. The control rod 90 causes rotation of the first rod 88 which pulls on the upstream end of the flap 81, which causes the upstream displacement of the pins 84 in the slideways 86, as shown in FIGS. 1, 2 and 4. The flap 81 is then in the open position and releases the opening. The movement of the support member 44 continues and the receiving surface 46 engages the opening to exit the internal volume.

At the end of the stroke of the actuating device, as shown in FIGS. 1 and 2, the support member 44 is in an extended position, in which the receiving surface 46 projects from the internal volume 12 through the opening and extends in a plane inclined with respect to the deployment direction. This inclined plane is for example substantially vertical or slightly inclined upstream relative to the vertical so that the receiving surface 46 extends in the field of view of a conductor when the support device 4 is installed in a dashboard. In this deployed position, as shown in Figs. 4 and 6, the ends 56 of the axis 54 are in the stop housing 24 of the first guide tracks 16 after engaging in the second sections 32 of these tracks 16 and the gear elements 60 are located in the stop slots 42 of the second guide tracks 34. Because of the respective position of these stop slots 24 and 42 at the downstream ends 20 and 38 of the first and second guide tracks 16 and 34, the shoulder 48 of the support member 44 then extends substantially in the direction of deployment, as shown in Figs. 1 and 2.

The displacement of the support member 44 between its retracted position and its deployed position is constantly accompanied by a cooperation between the two gear elements 54 and the toothed tracks 17. This cooperation makes it possible to avoid any risk of jamming. of the support device 4 and locking of the support member 44 in an intermediate position between the retracted position and the deployed position, ensuring that the support member 44 is maintained in a good position throughout and at all times its displacement between the retracted position and the deployed position. The displacement of the support member 44 from the extended position to the retracted position is in inverse kinematics to that described above, by actuating the motor 66 so as to drive the shaft 68 in a second direction opposite to the first sense. This movement has the effect of bringing back the ends 56 of the shaft 54 and the gear elements 60 towards the upstream ends 18 and 36 of the first and second guide tracks and thus to move the support element 44 into its position. retracted. At the end of the stroke of the first arm 70, it exerts a pressure on the actuating surface 98 of the second connecting rod 94, which has the effect of returning the flap 81 to its closed position, in which it closes the opening and masks the internal volume 12 and the mechanism of the support device 4. As indicated previously, in the deployed position, there is no play in the direction of elevation and in the direction perpendicular to the side walls 10 between the axis 54 and the side walls 10, because of the rollers 58 pressed against the ribs 26 and because of the narrowing of the width of the rails forming the first guide tracks 26, and between the gear elements 60 and the side walls 10, due to the reduction of the distance between the grooves 43 and the narrowing of the width of the groove 43. Thus, in the deployed position, the support member 44 is firmly held relative to the side walls according to the di The deployed position is therefore particularly stable and the receiving surface 46 and, where appropriate, the display panel 6 are immobile, even when a user manipulates those positions. this. In particular, the receiving surface 46 is not likely to move if a twist is exerted on it and particularly resistant to vibrations due to the operation of the motor vehicle. In addition, in the deployed position, the ends 56 of the axis 54 are arranged in the second sections 32 of the first guide tracks 16, which are inclined downward with respect to the deployment direction. This configuration provides stability to the deployed position in the direction of retraction, opposite the direction of deployment. Indeed, if a user exerts a force in the direction of retraction on the receiving surface 46, for example when the display device 1 is touch control, the ends 56 are then in abutment against the lower walls 22 of the slides forming the first guide tracks 26 and prevents any displacement of the support member 44 to the retracted position. Thus, the user has an impression of robustness when he presses the receiving surface 46, which remains stationary. Note in this regard that the second section 32 extends in a direction substantially parallel to the inclined plane in which the receiving surface 46 extends in the deployed position. This configuration further improves the stability of the support member 44 in the deployed position. Finally, this stability is further improved by the fact that the downstream ends 20 and 38 of the first and second guide tracks 16 and 34 do not extend in the same vertical plane, but are offset with respect to each other, which provides better resistance to an external force applied to the receiving surface 46 in the direction of retraction. The support device 4 described above is therefore particularly robust and reliable and offers great stability of the display device in the deployed position.
