In everything that follows, the orientations are the usual orientations of a motor vehicle. Thus, the terms "transverse", "longitudinal", "upper", "lower", "left", "right", "up" and "down" are understood in relation to the normal direction of circulation of a motor vehicle and relative to the position of a driver.

FIG. 1 illustrates a rear assembly 10 of a motor vehicle provided with an interior arrangement device 12 according to the invention.

The vehicle defines an interior passenger compartment 14 intended to receive the driver, the passengers and at least one interior equipment disposed in the passenger compartment, such as at least one vehicle seat 16.

The rear assembly 10 comprises a tailgate 18, a floor 20 and side trim 22.

The rear assembly 10 defines a rear trunk 24 of the motor vehicle.

The trunk 24 is a space delimited forwards by the seats 16 of the vehicle, on the sides by the side linings 22, downwards by the floor 20, upwards by the vehicle ceiling and rearwards by the movable tailgate 18.

The tailgate 18 is articulated on the body of the motor vehicle between a closed position for closing the trunk 24 and an open position for accessing the trunk 24.

The trunk 24 has a lower part 26 and an upper part 28 delimited between them by the device 12.

For example, the volume of the lower part 26 of the trunk 24 is adapted to contain a suitcase or heavy objects.

The device 12, illustrated in FIG. 2, is intended to close the lower part 26 of the trunk 24 upwards.

The device 12 comprises a support 30, at least one flexible layer 32 and at least one spring 34.

Advantageously, the device 12 further comprises at least one rail 35, at least one strap 36, two crosspieces 38, 40 and a handle 42.

The device 12 also comprises a mechanism 44 for locking the flexible layer 32.

In an advantageous embodiment, the device 12 also comprises an additional flexible layer 46.

The support 30 is intended to be fixedly mounted in the passenger compartment 14.

The support 30 advantageously comprises a first crosspiece 48.

The first crosspiece 48 is advantageously a tube made from a metallic material, in particular aluminum.

Alternatively, the tube could be made of plastic such as polypropylene or of composite.

The first crosspiece 48 extends along a transverse axis A-A ’.

The first crosspiece 48 advantageously has a length along the axis A-A ’substantially equal to the width of the trunk 24. By" substantially "means more or less 5%.

The support 30 is intended to be fixed to one of the interior fittings arranged in the passenger compartment 14. Advantageously, the support 30 is fixed by the two ends of the first cross-member 48 to the side fittings 22.

As a variant, said interior equipment is at least one of the seats 16.

The flexible layer 32 is operable between a position deployed in the passenger compartment 14 along an axis of deployment C-C ', shown in Figures 1 and 2 and a position wound around an axis B-B', shown in Figure 3, the coiled position constituting the rest position.

The axis B-B ’of rotation of the flexible layer 32 is advantageously orthogonal to the axis of deployment C-C’.

The axis B-B ’is advantageously a transverse axis, parallel to the axis A-A’. The first crosspiece 48 then extends orthogonally to the axis of deployment C-C ’.

The first crosspiece 38 is arranged at one end of the flexible layer 42 along the axis of deployment C-C ’.

The flexible layer 32 extends in a substantially horizontal plane in the deployed position. In particular, the flexible layer 32 is capable of projecting horizontally from the seat 16 in the deployed position.

The flexible layer 32 is advantageously made from polymer such as PVC (polyvinyl chloride), TPU (thermoplastic polyurethane) or from textiles such as nonwovens based on PET fibers (polyethylene terephthalate), or woven , or knitted.

The flexible layer 32 has a width less than the interior width of the trunk 24.

The flexible layer 32 has a length substantially equal to the length of the trunk 24.

The flexible layer 32 has a thickness advantageously between 0.3 mm and 3 mm.

The flexible layer 32 comprises, for each spring 34, a longitudinal pocket 50 receiving the spring 34.

Each pocket 50 extends along the axis of deployment C-C ’. Advantageously, each pocket 50 extends over the entire length of the flexible layer 32.

Each pocket 50 has a width greater than the width of the associated spring 34.

Each spring 34 is fixed to the flexible layer 32. In particular, each spring 34 is fixed to the flexible layer 32 by being inserted in a pocket 50 respectively of the flexible layer 32.

Alternatively each spring 34 is integral with the flexible layer 32. For example each spring 34 has been molded or welded to the flexible layer 32. In such cases, the pockets 50 are unnecessary.

Each spring 34 thus extends along the deployment axis C-C ’in the deployed position.

Each spring 34 urges the flexible layer 32 towards its wound position.

The unwinding of each spring 34 to pass it from the wound position to the deployed position is able to be ensured by the manual force of a user.

Each spring 34 can be wound together with the flexible layer 32 around the same axis B-B ’. The wound spring 34 is placed in the intermediate space 52 defined by the successive turns of the flexible layer 32 in the wound position.

Each spring 34 is made of metal. Alternatively each spring 34 is made of composite material.

Each spring 34 provides, in the deployed position, a lift along the horizontal plane of the device 12. The lift of a spring 34 results in resistance to bending under the effect of a weight.

In particular, the intrinsic stiffness of the material forming the springs 34 is capable of ensuring sufficient lift, in the deployed position, to support weights greater than 2 kg and advantageously between 0.5 kg and 5 kg.

The device 12 advantageously comprises at least two springs 34 arranged laterally on either side of the flexible layer 32 relative to the axis of deployment C-C ’.

Here, as shown in FIG. 2, the device 12 comprises three springs 34 including a spring 34 disposed in the middle of the flexible layer 32 relative to the axis of deployment C-C ’. This ensures better lift of the flexible layer 32.

Each rail 35 is fixed to a side trim 22 of the trunk 24.

Each rail 35 comprises two sections parallel to each other and separated by a space.

Advantageously, the device 12 comprises two rails 35 each fixed on a respective side trim 22, or formed in a respective side trim 22.

Each rail 35 extends longitudinally along the axis of deployment C-C ’between the seats 16 and the rear of the motor vehicle.

Each strap 36 is, for example, a cord or a band.

Each strap 36 extends along the axis of deployment C-C ’.

Each strap 36 is fixed to the two ends of the flexible layer 32 along the axis of deployment C-C ’.

Each strap 36 is thus in contact with the flexible layer 32.

Each strap 36 is advantageously in contact with the lower surface of the flexible layer 32. The straps 36 are thus not visible, in the deployed position, by a user observing the device from above, as shown in FIG. 4.

Here, as visible in FIG. 2, the device 12 comprises three straps 32.

Each of the straps 32 is arranged in contact with a respective pocket 50.

As can be seen in FIG. 2, the two cross-members 38, 40 extend orthogonally to the axis of deployment C-C ’.

The two sleepers are made up of a second sleeper 38 and a third sleeper 40.

The second crosspiece 38 advantageously has a length along the axis AA ’substantially equal to the width of the trunk 24.

In an advantageous embodiment, as visible in FIG. 4, each end of the second crosspiece 38 is suitable for cooperating with a respective rail 35. The second cross member 38 is thus able to slide longitudinally in translation along the axis of deployment C-C ’, the movement being guided by the two rails 35.

The second crosspiece 38 is able to cooperate with at least one of the strips 36. Here, the second crosspiece 38 cooperates with the three strips 36.

The second crosspiece 38 has at least one reception guide 54.

Each reception guide 54 is suitable for receiving a strap 36, the strap 36 being inserted along the axis of deployment C-C ’. Each reception guide 54 is for example a passer-by fixed on the body of the cross-member 38.

Here, the second crosspiece 38 comprises three reception guides 54, spaced transversely, each reception guide 54 each guiding a respective strap 36.

The third crosspiece 40 is disposed at one end of the flexible layer 42 along the axis of deployment C-C ’, opposite the first crosspiece 48.

The flexible layer 32 thus extends along the axis of deployment C-C ’between the first cross member 48 and the third cross member 40.

The handle 42 is fixed to the second crosspiece 38.

The handle 42 is advantageously fixed in the middle of the second crosspiece 38.

The handle 42 is for example made up of a pass, the two ends of the pass being fixed to the second cross 38.

The handle 42 is advantageously rigid and fixed relative to the second crosspiece 38.

When the device 12 is in the rolled up position, the handle 42 is suitable for being gripped by a user in order to exert a tensile force on the handle 42 making it possible to pass the flexible layer 32 from the rolled up position to the deployed position, as shown in Figure 4.

The blocking mechanism 44 comprises a blocking member linked to the flexible layer 32. In particular, the blocking mechanism 44 comprises a blocking member linked to the second crosspiece 38.

In this example, the blocking member is formed by the end of the second cross member 38

The locking mechanism 44 is able to keep the flexible layer 32 in the deployed position.

As illustrated in FIG. 6, in an advantageous embodiment, the locking mechanism 44 also comprises at least one notch 56 defined on one of the profiles of one of the rails 35.

Advantageously, each notch 56 is defined in the bottom profile, as visible in FIG. 6.

As a variant, each notch 56 is defined in the top profile.

Each notch 56 is able to cooperate with one of the ends of the second crosspiece 38.

Each notch 56 includes a stop 58 and a ramp 60.

The stop 58 is able to block the movement of the second cross member 38 in translation towards the first cross member 48.

The stop 58 therefore opposes the force of the spring 34 urging the flexible layer 32 towards its wound position.

The ramp 60 makes the junction between the stop 58 and the rest of the rail 35. The ramp 60 allows the second cross member 38 to pass a free configuration, illustrated in FIG. 6, in which the second cross member 38 flows freely in the rail 35 in a blocked configuration in which the second cross member 38 cooperates with the stop 58 and in which the movement of the second cross member 38 in translation towards the first cross member 48 is blocked.

The locking mechanism 44 advantageously comprises between 1 and 3 notches 56.

Thus, the locking mechanism 44 is able to maintain the flexible layer 32 in intermediate positions between the rolled-up position and the deployed position, as for example visible in FIG. 4.

As can be seen in FIG. 5, the additional flexible layer 46 is advantageously arranged in contact with the flexible layer 32.

The additional layer 46 has greater sound insulation and / or thermal insulation than the flexible layer 32. The additional flexible layer 46 therefore makes it possible to obtain sound insulation and / or thermal insulation of the device 12 improved.

The additional flexible layer 46 is advantageously made from foam preferably made of PUR (Polyurethane), or else felt based on PET fiber (Polyethylene terephthalate).

The additional flexible layer 46 has longitudinal and transverse dimensions substantially equal to those of the flexible layer 32.

The additional flexible layer 46 has a thickness advantageously between 3 mm and 10 mm.

The operation of the device 12 in a passenger compartment assembly will now be described.

Initially, the device 12 is fixed in the trunk 24, behind the rear seat 16.

In particular, the first crosspiece 48 is fixed to the side linings 22.

Each end of the second cross member 38 cooperates with a respective rail 35 located in the side fittings 22 of the car.

The transition from the rolled up position to the deployed position will now be described.

The flexible layer 32 is in the wound position, as illustrated in FIG. 3.

The lower part 26 of the trunk 24 is then visible and accessible by a user.

The user advantageously places suitcases or heavy objects in the trunk 24.

Then, the user grasps the handle 42 and exerts a pulling force towards the rear.

The second cross member 38 then slides in translation in the rails 35 towards the rear of the vehicle.

By sliding, the second crosspiece 38 drives the strips 36 with which it cooperates. Thus, the strips 36 are unwound, each being guided by a receiving guide 54.

The straps 36 being fixed to the flexible layer 32, the straps 36, in unwinding, drive the flexible layer 32 and simultaneously the springs 34. Thus, the torque layer 32 takes place jointly with the straps 36, against the loading of the springs 34 as visible in FIG. 4.

In particular, the force exerted by the user is greater than the restoring force of the springs 34 urging the flexible layer 32 towards its wound position.

The flexible layer 32 then passes from the wound position to the deployed position, shown in FIGS. 1, 2 and 5.

When the flexible layer 32 is in the position desired by the user, the latter blocks the flexible layer 32 by means of the locking mechanism 44. In particular, the user places each end of the second crosspiece 38 in one of the notches 56 by exerting a downward force on the handle 42 when the second cross member 38 is located at the level of said notches 56.

Each end of the second cross member 38 then cooperates with the stop 58 of the respective notch 56 under the effect of the bias of the springs 34. The movement of the second cross member 38 in translation towards the first cross member 48 is thus blocked.

The flexible layer 32 is then blocked in the deployed position.

The device 12 masks the content of the lower part 26 of the trunk 24. The user releases the handle 42.

Advantageously, the user places objects on the upper surface of the flexible layer 32, the springs 34 deployed ensuring sufficient lift.

The transition from the deployed position to the rolled position will now be described.

The user removes any objects placed on the upper surface of the flexible layer 32.

The user grasps the handle 42 and exerts a pulling force in order to slide each end of the second cross member 38 onto the associated ramp 60 and thus bring the ends of the second cross member 38 out of the notches 56.

The springs 34 then urge the flexible layer 32 towards its wound position.

The user accompanies the translational movement of the second cross member 38 towards the front of the car along the axis of deployment C-C ’.

The springs 34 are wound together with the flexible layer 32 around the same axis B-B ’until the flexible layer 32 is in the wound position.

The user then releases the handle 42.

Advantageously, the user removes the suitcases or heavy objects present in the trunk 24.

The operation of the device 12 is therefore very simple for the user.

The springs 34 allow the flexible layer 32 to easily and effortlessly pass from the deployed position to the wound position.

In the deployed position, the springs 34 ensure good lift of the flexible layer 32, allowing the flexible layer 32 to support objects placed on its upper surface. They are nevertheless effectively masked by layer 32.

The mechanism of the device 12 is thus simplified in order to make the device 12 more compact and less heavy in comparison with the devices known from the prior art.

Manufacturing cost savings are thus obtained.

A second interior arrangement device, not shown, will now be described.

The second device differs from the device 12 in that the first crosspiece 48 is not fixed in the passenger compartment 14.

Each end of the first cross member 48 cooperates with a respective rail 35. The first crosspiece 48 is thus able to slide longitudinally in translation along the axis of deployment C-C ’, the movement being guided by the two rails 35.

The handle 42 is provided on the first crosspiece 48.

The second device differs, moreover, from the device 12 in that the second crosspiece 38 is fixed to the passenger compartment 14.

The second cross-member 38 is intended to be fixed to one of the interior equipment arranged in the passenger compartment 14. Advantageously, said interior equipment is at least one of the seats 16. As a variant, the second cross-member 38 is fixed by the two ends of the second crosspiece 38 to the side linings 22.

The flexible layer 32 extends from the third cross member 40 to the first cross member 48 when moving towards the rear of the vehicle.

The operation of the second device is similar to the operation of the device 12.

A third interior arrangement device, partially shown in Figures 7 and 8, will now be described.

The third arrangement device differs from device 12 in that the locking mechanism 44 does not include notches 56.

As shown in Figures 7 and 8, the second crosspiece 38 has an elliptical section in a plane orthogonal to the transverse axis A-A ’. As a variant, only the ends of the second crosspiece 38 have an elliptical section in a plane orthogonal to the transverse axis A-A ’.

The greatest length of the ellipse is less than the distance separating the two edges of the associated rail 35.

The locking member of the mechanism 44 is capable of changing from a free configuration, visible in FIG. 7, to a blocked configuration, visible in FIG. 8.

In the free configuration, the second cross member 38 is oriented so that the greatest length of the ellipse extends along the axis of unfolding C-C ’.

The second cross member 38 is then free to slide in the rails 35 in translation along the axis of deployment C-C ’.

In the locked configuration, the second cross member 38 is oriented so that each end of the second cross member 38 is in contact with the two profiles of the associated rail 35.

Thus, the movement of the second crosspiece 38 in the rails 35 is blocked by friction.

The operation of the third device differs from the operation of the device 12 in that the blocking of the flexible layer 32 in the deployed position is effected by a rotational movement of the second crosspiece 48 about its axis.

When the user pulls the handle 42 in order to pass the flexible layer 32 from the wound position to the deployed position, the locking mechanism 44 is in the free configuration.

When the second crosspiece 38 is in the position desired by the user, the user exerts a torque on the handle in order to rotate the second crosspiece 38 about its axis.

The locking mechanism 44 then changes from the free configuration to the blocked configuration.

The user then releases the handle 42 and the flexible layer 32 is locked in the deployed position.

Conversely, when the user wishes to pass the flexible layer 32 from the deployed position to the rolled position, the user grasps the handle 42 and exerts a torque in the opposite direction to the previous torque in order to pass the second cross member 38 of the configuration blocked in free configuration.

The flexible layer 32 is then free to pass from the deployed position to the wound position.

A fourth interior arrangement device, not shown, will now be described.

The fourth arrangement device differs from device 12 in that the locking mechanism 44 does not include notches 56.

The second cross member 38 comprises two studs, each stud being located at one end of the second cross member 38.

Each stud is able to pass from an inserted position in which the stud is fully inserted into the second crosspiece 38, to an extended position in which the stud protrudes at least partially relative to the second crosspiece 38 along the axis A- AT'.

The device 12 further comprises a movement mechanism capable of moving each stud from the inserted position to the extended position. The activation mechanism is for example a latch cooperating with the pins.

The side fittings 22 each define at least one hole of complementary shape with the pins.

In the deployed position, each stud is suitable for being inserted into one of the holes in the side linings in order to block the movement of the second cross member 38 in the rails 35.

The operation of the fourth device differs from the operation of the device 12 in that the user blocks the flexible layer 32 in the deployed position by actuating the movement mechanism in order to move the pins from the inserted position to the output position. Each stud protrudes from the second cross member 38 and fits into one of the holes in the side linings 22.

The movement of the second crosspiece 38 in the rails 35 is then blocked and the flexible layer 32 is blocked in the deployed position.

Conversely, when the user wishes to pass the flexible layer 32 from the deployed position to the wound position, the user actuates the movement mechanism in order to move the pins from the extended position to the inserted position.

The flexible layer 32 is then free to pass from the deployed position to the wound position 5.

The invention corresponds to all technically possible combinations of the embodiments previously described.

In particular, it is possible to use the device by deploying it along the transverse axis of the vehicle between the two lateral linings 22. In such a case, the rails 10 are optional. Intermediate positions are no longer necessary.

Similarly, it is possible to use any possible type of blocking of the second cross member 38 in the rails 35.
