The assembly 1 shown in FIGS. 1 to 3 is intended to be installed inside a vehicle, typically a motor vehicle such as a car or a truck.

This assembly is more specifically intended to be installed in the passenger compartment of the vehicle.

The assembly is for example intended to be integrated in the dashboard of the vehicle, in a door panel, in the central console, in the back of a seat, or in any other suitable structure of the vehicle.

The assembly 1 comprises a fixed structure 3 and a plurality of movable elements 5, arranged side by side in a direction of juxtaposition (FIG. 2).

The interior assembly 1 also comprises an actuator device 7, illustrated in FIGS. 4 to 12, arranged to move the movable elements 5 between at least a first configuration and a second configuration.

4 The interior assembly 1 preferably comprises a flexible skin 9, itself comprising a plurality of sections 11 each rigidly fixed to one of the movable elements 5, and a plurality of free sections 13 connecting the sections 9 fixed to each other.

The supple skin is shown only in Figures 1 and 3.

In FIG. 5 1, the mobile elements 5 are masked by the flexible skin 9.

The free sections 13 are arranged between the fixed sections 11, and therefore allow the movable elements 5 to move relative to each other.

The flexible skin is made of an elastomer type stretchable material which may be a TPU (thermoplastic polyurethane).

Alternatively, the soft skin is elastomeric silicone, is a three-dimensional knitted fabric, or is synthetic rubber.

The movable elements 5 are movable relative to the fixed structure 3 in respective movement planes, parallel to each other.

Typically, the displacement planes are perpendicular to the juxtaposition direction in J, materialized by a phantom line in Figures 1 and 2.

The fixed structure 3 is for example a lining, intended to be mounted in the passenger compartment.

It typically comprises a panel 14, having a surface 15 visible to the passengers of the vehicle.

The fixed structure 3 also comprises an internal housing 16, opening into the passenger compartment of the vehicle through an opening 17 cut in the panel 14.

The peripheral edge of the flexible skin can be fixed on the internal surface of the panel 14, around the opening 17.

In an alternative embodiment, in the case of an attached part (see FIG. 3), the skin of the fan-type part 9 is independent of the skin of the peripheral panel.

The actuator device 7 is housed in the internal housing 16, and is therefore not visible to the passengers.

Typically, the mobile elements 5 are linked to the fixed structure 3 by respective pivot links 18.

The pivot links 18 typically have the same pivot axis.

This pivot axis typically corresponds to the direction of juxtaposition.

The number of movable elements 5 and the size of each movable element 5 depends on the envisaged application.

The movable elements 5 are preferably all identical.

Each movable element 5 has, for example, the general shape of a quarter-circle (FIG. 2) or a quarter-disc (FIGS. 4 to 9).

In the example of FIG. 2, each movable element 5 comprises a rectilinear branch 35 extended by an arcuate branch. The pivot link 18 is placed at one end of the rectilinear branch.

The arcuate branch extends from the end of the straight branch opposite the pivot link 18.

As a variant, the mobile elements 5 are triangular.

According to another variant shown in FIG. 3, the movable elements are fingers.

Thus, each mobile element 5 has a flat surface 19.

The fixed sections 11 of the flexible skin are fixed to the flat surfaces 19.

They are fixed by any suitable means, for example glued locally.

The actuator device 7 is arranged to move the movable elements 5 between two configurations.

As a variant, it is arranged to move the movable elements 5 so as to form three configurations or more than three configurations.

By configuration is meant here a set of determined positions of the movable elements 5, so that these movable elements 5 and the flexible skin 9 together adopt a determined shape.

The movable elements 5 in the second configuration, illustrated in particular in Figures 1, 2 and 9, form a bearing surface 20.

The bearing surface 20 is covered by the flexible skin 9.

The bearing surface 20 is strongly protruding from the visible surface 15.

It is for example substantially horizontal.

The support surface 20 is advantageously a support surface for a passenger of the vehicle.

The movable elements 5 in the second configuration advantageously form an armrest or a tablet.

For example, the mobile elements 5 in the first configuration are retracted inside the fixed structure 3.

25 They are housed in internal housing 16.

Advantageously, the flat surfaces 19 fit into the opening 17.

The fixed sections 9 of the skin form a quasi-continuous surface, closing the opening 17.

The bearing surface 20 is formed by the flat surfaces 19 of at least part of the movable elements 5, which are part of the same plane.

More precisely, the mobile elements 5 are arranged along a line.

In the first configuration, a group of movable elements 5, here called main group 21, are in the same angular position around the axis of rotation.

A small group of elements 5, here called transition group 22, located at a first end of the line, is deployed as a fan.

6 The flat surfaces 19 of the movable elements 5 of the main group 21 are part of the same plane.

This plane corresponds to the bearing surface.

The movable elements 5 of the transition group 22 occupy angular positions which gradually approach the angular position of the movable elements 5 of the main group 21.

Thus, the movable element 5 located at the first end of the line is relatively more angularly offset with respect to the movable elements 5 of the main group.

The neighboring mobile element 5 is a little less offset from the main group, etc.

Such a fan-shaped arrangement is made possible by the existence of free sections 13 of the flexible skin.

The free sections 13 located between the movable elements 5 of the main group 21 are folded between said movable elements.

On the contrary, the sections 13 located between the movable elements 5 deployed in a fan are stretched (Figure 3).

According to a first embodiment illustrated in FIGS. 4 to 9, the actuator device 7 comprises a plurality of intermediate links 23 capable of selectively joining or separating the mobile elements 5 from each other, at least for the movement between the first and second configurations.

In Figures 4 to 9, only five movable elements 5 are shown for clarity, but the interior assembly may include any number of movable elements 5.

The actuator device 7 then also comprises an actuator 25, arranged to move a movable element called leader 26 among the movable elements 5 between a first and a second position.

In the exemplary embodiment illustrated, the movable leading element 26 is located at a second end of the line of movable element 5.

The second end is opposite the first in the direction of juxtaposition.

Each mobile element 5 is associated with one of the intermediate links 23, with the exception of the mobile element 5 located at the first end or at the second end of the line.

More precisely, the intermediate link 23 has unlocked 30 and locked positions, illustrated respectively in FIGS. 5 and 6.

In the locked position, the associated mobile element 5 is integral with the neighboring mobile element 5 in the line towards the second end.

In the unlocked position the movable element 5 is free vis-à-vis said neighboring movable element 5.

As a variant, in the locked position of the intermediate link 23, the associated movable element 5 is secured to the neighboring movable element 5 towards the first end.

7 Each intermediate link 23 comprises a finger 27 and a lever 28 for controlling the finger 27.

The finger 27 is elongated parallel to the direction of juxtaposition.

It is guided in translation in the direction of juxtaposition in a tubular guide duct 29 formed on the corresponding mobile element 5.

The neighboring movable element 5 for its part comprises an orifice 31 in which a free end 33 of the finger 27 is received in the locked position.

The lever 28 comprises two legs 35 substantially parallel to one another, connected to one another by a head 37.

The legs 35 are pivotally mounted on the movable element 5, around respective axes 39 aligned with one another.

The pivot axes 39 are perpendicular to the direction of juxtaposition.

As can be seen in FIGS. 5 and 6, the legs 35 are arranged on either side of a block 41 of the corresponding mobile element 5.

The guide duct 29 is formed in the block 41.

An oblong hole 43 is made at the free end of each leg 35, that is to say opposite the head 37.

The finger 27 has two diametrically opposed lugs 45, each lug 45 being engaged to slide freely in the oblong hole 43 of one of the two legs 35.

The lugs 45 slide along two slots 47, oriented parallel to the direction of juxtaposition, opening into the guide duct 29.

When the head 37 of the lever is angularly offset on one side around the pivot axes 39, to the left in the representation of Figures 5 and 6, the lugs 45 are moved by the legs 35 at one end of the slots 47.

In the example shown, this corresponds to the unlocked position of the intermediate link 23 When the head 37 is angularly offset on the opposite side around the pivot axes 39, on the right side in the representation of Figures 5 and 6, the pins 45 are moved by the legs 35 to the opposite end of the slots 47.

This corresponds to the locked position of the intermediate link 23 in the example shown.

The movable elements 5 are mounted to pivot around a rod 48 (FIG. 4).

The rod 48 is fixed to an internal surface of the panel 14, which is intended to be invisible to the passengers.

Likewise, the actuator 25 is located in the internal housing 16, not visible, of the fixed structure 3.

The actuator device 7 furthermore comprises an elastic member 49, returning all the movable elements 5 to the rest positions.

The rest positions are shown in Figure 4.

Typically, the first configuration corresponds to the configuration where all the mobile elements 5 are in their rest position.

In this position, the orifices 31 are aligned with the corresponding fingers 27, so that each intermediate link 23 can be selectively placed in the locked position or in the unlocked position.

So as to allow an adjustment of the number of movable elements 5 belonging to the main group 21 in the first configuration, the actuator device 7 comprises an adjustment 51, visible in particular in FIGS. 4 and 7.

This makes it possible, for example, to adjust the length of the armrest or the length of the tablet.

As can be seen in Figures 4 and 7, in the rest position of each movable element 5, the heads 37 of the different levers 28 are substantially aligned, in a direction parallel to the direction of juxtaposition.

The heads 37 are turned towards the panel 14 of the fixed structure 3.

Each head 37 has, perpendicular to the pivot axis 39, a V-shape.

It therefore comprises two wings 53, 55 pointing towards the arms 35.

As can be seen in FIG. 7, when the movable elements 5 are in the rest position and the intermediate links 23 in the unlocked position, the wings 55 are located in the same plane P1.

This plane is parallel to the direction of juxtaposition.

The wings 53 protrude from the plane P1 towards the panel 14.

Conversely, when the movable elements 5 are in the rest position and the intermediate links 23 in the locked position, the wings 53 are located in the same plane parallel to the direction of juxtaposition, typically in the plane P1.

The wings 55 protrude from the plane towards the internal surface of the fixed structure 3.

The adjustment 51 is arranged to place in the unlocked position the intermediate links 23 associated with one or more successive movable elements 5, from the first end of the line, 25 The movable elements 5 whose links 23 are in the locked position constitute the group. main 21.

They move in conjunction with the lead element 26.

The movable elements 5 whose intermediate links 23 are in the unlocked position are not blocked in the same angular position as the movable leading element 26.

When the actuator 25 moves the movable lead member 26 to its second position, said movable members 5 fan out, as illustrated in Figures 1 and 2.

They constitute the transition group 22.

Adjustment 51 typically includes a slider 61, slidably mounted on the inner surface of panels 14, in a direction parallel to the direction of juxtaposition.

The cursor 61 has an actuating edge 63 situated flush with the plane H.

9 Furthermore, the panel 14 has a slot 65 (FIG. 4), the cursor 61 having an actuator 67 engaged in the slot 65 and protruding with respect to the visible surface 15 of the panel 14.

When the slider 61 is located at one end of the slot 65, the right end in the illustration of FIG. 7, it is placed substantially at the level of the first end of the row of movable elements 5.

When the movable elements 5 are in the rest position and the intermediate links 23 are all in the locked position, a movement of the cursor 61 towards the second end of the line will cause the intermediate links 23 to pass into the unlocked position.

The number of intermediate links 23 passing in the unlocked position 10 depends on the amplitude of the movement of the cursor 61.

The actuator 25 also comprises a cable 69, one end 70 of which is rigidly fixed at a point of the movable driving element 26.

The cable 69 is returned by one or more pulleys 71 to a drum 73, capable of being driven in rotation by a motor 75.

The other end of the cable 69 is rigidly fixed to the drum 73.

The end 70 of the cable is fixed at a point of the movable lead element 26 chosen so that, when the motor 75 drives the drum 73 in the direction of winding of the cable 69 around the drum 73, the movable element 5 is displaced in rotation from its rest position, against the elastic return force of the elastic member 49.

The operation of the interior assembly 1 provided with the actuator device 7 according to the first embodiment will now be detailed.

It is considered that in the initial situation, all the mobile elements 5 are in their rest position.

The intermediate links 23 are all in the locked position.

The cursor 61 is located at the end of the slot 65 furthest from the movable leader element 26.

The user first sets the length of the bearing surface 20 using the setting 51.

To do this, he moves the cursor 61, using the actuator 67.

The cursor 61 first passes in front of the lever 28 mounted on the movable element 5 furthest from the leading element 26.

By the way, it pushes on the wing 55 which causes the rotational displacement of the lever 28 with respect to the movable member 5.

This rotation causes the corresponding intermediate link 23 to move from the locked position to the unlocked position.

The cursor 61 then places at the level of the movable element 5 immediately adjacent in the line towards the second end.

The user can thus unlock the intermediate links 23 of one or more mobile elements, from the end of the line opposite to the mobile lead element 26, as illustrated in FIG. 7.

Then, the user triggers the actuator device 7, so as to change the mobile elements 5 from the second configuration to the first configuration.

To do so, the user actuates a control member, not shown.

This has the effect of activating the motor 75, which rotates the drum 73 in the direction of winding the cable 69 around the drum 73.

Under the effect of the winding of the cable 69, the movable driving element 26 is displaced in rotation about the axis of rotation.

It moves to a second position, 10 corresponding to the second configuration.

In the example shown, in the first configuration, the flat surface 19 of the movable driver element 26 is substantially horizontal and projects from an outer side of the fixed structure 3, towards the passenger compartment of the vehicle when the surface of support is an armrest.

The movable elements 5, the intermediate links 23 of which are in the locked position, together with the movable leading element 26 constitute the main group 21.

These movable elements 5 move in rotation together.

They are locked in an angular position relative to each other.

The flat surfaces 19 of the movable elements 5 of the main group remain in the same plane, and define the bearing surface 20.

The mobile elements 5, the intermediate links 23 of which are in the unlocked position, constitute the transition group 22.

They are not angularly locked in rotation with respect to the movable elements 5 of the main group 21.

Under the effect of the rotation of the movable elements 5 of the main group 21, these movable elements 5 are deployed in a fan pattern as illustrated in FIG. 2.

The movable element 5 which adjoins the movable elements 5 of the main group 21 in the line is driven by the free section 13 of the flexible skin 9 which connects it to the neighboring movable element 5.

Its angular offset with respect to the main group 21 is adjusted by the size of the free section 13 of the flexible skin 9.

Likewise, the mobile element 5 of the transition group 22 located immediately next to the preceding one is driven by said preceding mobile element 5, via the free section 13 which connects them.

Thus, the mobile elements 5 of the second group 22 are driven by each other via the free sections 13.

If the user wants to return the movable elements 5 to the first configuration, he commands the motor 75 to drive the drum 73 in the direction of unwinding of the cable 69.

The elastic element 49 then returns the movable elements 5 all to their rest positions.

The user, if he wishes to modify the length of the bearing surface for later use can then move the cursor 61 either towards the first end of the line of movable elements or towards the second end of the line. line.

If it moves the cursor 61 towards the first end of the line, the actuating end 63 will successively tilt the levers 28 of one or more of the intermediate links 23 into the locked position.

A second embodiment of the vehicle interior assembly will now be detailed, with reference to Figures 10 to 13.

Only the points by which this interior assembly differs from that of the first embodiment will be detailed below.

The elements which are identical or which perform the same functions will be designated by the same references in the two embodiments.

The second embodiment of the invention differs from the first only by its actuator device 7.

In the second embodiment, the actuator device 7 does not have any intermediate links between the mobile elements 5.

The mobile elements 5 are independent of each other.

The actuator device 7 on the other hand comprises a cam 77 and an actuator 79 arranged to move the cam 77 between first and second positions.

Each movable element 5 comprises a cam follower 80 cooperating with the cam 77, so that the movable elements 5 adopt the first configuration when the cam 77 occupies the first position, and adopts the second configuration when the cam 77 occupies the second position. .

In the example shown in Figures 10 to 12, the cam follower 80 is a link.

The cam follower 80 thus has a first end 81 pivotally mounted on the corresponding movable element 5, and a second end 83 pivotally mounted on a slide 85.

The axes of rotation of the ends 81 and 83 are substantially parallel to the direction of juxtaposition.

The slider 85 is slidably mounted along a guide rod 87.

The guide rods 87 are all parallel to each other, and are typically arranged in the same plane.

The guide rod 87 associated with a determined mobile element 5 is perpendicular to the direction of juxtaposition, and extends in the displacement plane of the corresponding mobile element 5.

The first end 81 of the cam follower is linked to a point of the movable member 5 chosen so that, when the slider 85 moves towards one end of the guide rod 87, the movable member 5 is moved towards its second. position, and when the slider 85 moves towards the opposite end of the guide rod 87, the movable element 5 is driven towards its rest position.

In the representation of Figures 10 to 12, the downward movement of the slide drives the movable element 5 to its second position, and the upward movement to its rest position.

The cam 77 cooperates with the slides 85.

To do this, the cam 77 comprises, for example, a plurality of actuating rods 89.

These actuator rods 89 have different heights.

The cam 77 is attached to a belt 91, arranged in a loop around two opposite wheels 93, 95.

The actuator 79 is configured to circulate the belt 91 around the wheels 93 15 95.

Typically, the actuator 79 drives one of the two wheels in rotation.

The actuator rods 89 are juxtaposed along the belt, as shown in Figure 12.

Each rod 89 has an end 96 fixed to the belt 91, and a free end 97 opposite the belt 91.

The respective heights of the actuating rods 89 are chosen such that the free ends 97 of the rods 89 form a cam surface of predetermined shape.

In the example shown, this cam surface comprises a first section 99 forming a rising edge in S, then a plate 101, then a second section 103 forming a falling edge in S.

The actuating rods 89 circulate around the wheels 93, 95 with the belt 91.

The first position of cam 77 is shown in solid lines in Figure 12.

The actuating rods 89 are then placed above the belt 91.

The second position of the cam 77 is shown in Figure 12 in broken lines.

The actuating rods 89 are then placed under the belt 91.

The cam 77 is placed at the level of the guide rods 87.

As illustrated in FIG. 13, the rods 89 have openings 105 which allow the slides to be progressively guided.

Cam 77 could be of a different type from that shown in Figure 12.

The cam 77 could for example be a plate movable in the direction of juxtaposition, this plate comprising a cam track in which are engaged lugs integral with the slides 85.

Under the effect of the movement of the cam 77 13 in the direction of juxtaposition, the slides 85 are driven along the guide rods 87, thus causing the movement of the movable elements 5.

Such an arrangement, with a cam moved by an actuator, has the advantage of creating a wave movement of the mobile elements 5.

The movable elements 5 are moved successively, starting from one end of the line towards the other end of the line.

Such a movement is pleasant for the passengers of the vehicle.

Advantageously, the assembly 1 comprises locks 111 reversibly locking the movable elements 5 in the second configuration.

These 10 interlocks are shown schematically in Figure 4.

They are designed to stabilize the movable elements 5 in the second configuration, in particular when the movable elements 5 in this second configuration form a bearing surface 20.

The user can thus place his arm or place heavy elements on the bearing surface 20, without causing the movable elements 15 to return to their rest positions.

The locks 111 are however sized so as not to prevent the return of the movable elements 5 to their rest position under the effect of the force applied by the actuator device 7.

The locks 111 are of any suitable type.

For example, these are clips.

In this case, the locking 111 comprises for each mobile element a head 113 rigidly fixed to the corresponding mobile element 5, which is clipped into a clamp 115 mounted on the fixed structure 3 when the mobile element 5 arrives in its second position. .

As a variant, the locking is magnetic or of any other suitable type.

The interior assembly of the invention can have multiple variations.

The mobile elements may not be connected to each other by a flexible skin but by other suitable means (straps, etc.).

In a non-preferred embodiment, they are not connected to each other but are guided only by the actuator device.

In the first configuration, the movable elements may not be retracted inside the fixed structure, and remain prominent.

It is possible to provide several configurations capable of being adopted successively by the mobile elements moved by the actuator device.

The intermediate bonds are not necessarily of the type described above.

14 These connections can be magnetic, or be mechanical, but be made by any other suitable mechanical device.

The vehicle interior assembly has multiple advantages.

It allows multiple shapes to be created on the fixed structure, which shapes can be highly prominent.

This result is obtained with a mechanically simple device that takes up little space.

This mechanism is compact enough to be housed, for example, in a door panel.

The invention makes it possible to temporarily create a support surface such as an armrest or a tablet.

This surface can then be retracted very easily.

The space requirement is minimum once the bearing surface has been retracted.

The supple skin works like a fan.

The relative movements of the various movable elements with respect to one another can be of great amplitude, owing to the fact that a plurality of free sections is provided in the flexible skin, between the sections rigidly fixed to the mobile elements.

This makes it possible in particular to create reliefs that are highly prominent with respect to the surface of the fixed structure, and to retract them.

Providing that the movable elements move in planes perpendicular to the direction of juxtaposition makes it possible to move the movable elements very easily, without risk of interference between them.

The pivot connections of the various mobile elements make it possible to move these mobile elements between the various configurations in a simple and convenient manner.

The volume swept by moving parts inside the vehicle as they move is minimal.

The fact that each mobile element has a flat surface and that the flat surfaces of at least some mobile elements are part of the same plane in the second configuration, makes it easy to create a support surface such as an armrest or a tablet.

The shape of the movable elements in a quarter-circle makes it possible to have a flat bearing surface and facilitates the passage from one configuration to another with respect to the fixed structure, in particular when the movable elements move in rotation around it. an axe.

Due to the fact that the fixed sections of the flexible skin are rigidly fixed to the flat surfaces, a fan structure is easily created, making it possible to obtain structures that are highly prominent with respect to the fixed structure.

The use of an actuator device with intermediate links capable of selectively joining or separating the movable elements from one another and of an actuator arranged to move a movable leading element, makes it possible to conveniently move the movable elements between the first ones. and second configurations.

Some of the movable elements are moved together, the other movable elements being driven by the flexible skin.

The adjustment advantageously makes it possible to vary the number of movable elements driven together with the movable leading element.

This is particularly advantageous for an armrest or a tablet, since the length of the support surface 10 is thus adjusted.

When the actuator device comprises a cam and an actuator arranged to move the cam, it is possible to create an attractive, wave-like movement.
