Description

Title of the invention: Device for securing at least one object to a rigid rear shelf of a motor vehicle. Technical field

[0001] The invention relates to a device for securing at least one object to a rigid rear shelf of a motor vehicle. The invention relates in particular to a device for holding and / or immobilizing at least one object in contact with a rigid rear shelf of a motor vehicle, the rigid rear shelf being of the type comprising at least one set of at least two through openings. The invention also relates to a rigid rear shelf of a motor vehicle equipped with such a securing device and to a motor vehicle equipped with such a rigid rear shelf. Previous technique

[0002] FR3049533 is known as a device for securing an object such as a bottle or jerrycan in the trunk of a motor vehicle. The securing device of FR3049533 comprises a vertical wall of the trunk of this motor vehicle, the vertical wall having an inner face facing the interior of the vehicle and an outer face opposite the inner face. The vertical wall has two through-holes, spaced apart in a longitudinal direction parallel to the X-axis of a direct orthonormal coordinate system. Each through-hole extends lengthwise in a vertical direction parallel to the Z-axis of the same direct orthonormal coordinate system. The securing device also includes an elastic strap that, together with the wall, defines a compartment for inserting the bottle or jerrycan and is adapted to be deformable and elastically pulled into a position for securing the bottle or jerrycan against the wall.Each end of the elastic strap of the FR3049533 restraint device is fixed to a self-locking element that irreversibly secures this end of the elastic strap to the wall. Each self-locking element consists of a radially toothed pin forming a rack, passing through the wall and having a retaining collar for the pin on the inner face of the wall, and a washer cooperating with the toothed pin to tighten the self-locking element against the wall without the possibility of the washer moving back or the self-locking element loosening.

[0003] The object retention device of FR3049533 is limited in its use to holding bulky and heavy objects such as a bottle or jerrycan in the trunk of a motor vehicle. It does not allow for holding or immobilizing at least one object in contact with a rigid rear shelf of a motor vehicle. It does not does not allow for holding and immobilizing against a rigid rear shelf of a motor vehicle, at least one thin object, in particular one thinner than the distance between the strap and the wall.

[0004] The invention aims to overcome these drawbacks.

[0005] Furthermore, the self-locking fasteners that irreversibly secure the strap to the inner face of the wall are not removable and do not allow the strap to be detached from the wall or moved on the wall. This is all the more true since the washers cooperating with each toothed pin extend to the outer face of the wall and are not accessible. The self-locking fasteners that irreversibly secure the strap to the inner face of the wall are therefore not removable, and the strap is permanently fixed to the wall and cannot be detached from it.

[0006] The invention aims to overcome these drawbacks and in particular aims to provide a removable object holding device, which is fixed like the object holding device of FR3049533.

[0007] FR3081137 is also known as a device for securing an object in a motor vehicle, comprising a support with two slots and a strap passing through each slot. The support is a side trim piece in the trunk of this motor vehicle, and the fastening device is intended to hold objects against the side trim piece in the trunk's interior space. The central portion of the strap extends along the inner face of the side trim piece. Each longitudinal end portion of the strap of the fastening device of FR3081137 extends along the outer face of the side trim piece and is irreversibly held in place on this face by a butterfly-shaped fold of the strap around a metal loop and a seam of the strap upon itself, preventing the strap from detaching.The FR3081137 object securing strap is permanently mounted to the outer face of the trunk side trim and is not detachable from the trunk side trim. Furthermore, the FR3081137 object securing strap requires access to both the inner and outer faces of the trunk side trim for its final installation. Therefore, the FR3081137 object securing strap can only be installed during vehicle assembly on an assembly line.

[0008] The invention aims to overcome these drawbacks.

[0009] The invention aims in particular to provide a device for fixing an object using means that are simpler than those of FR3081137.

[0010] A device for attaching objects to the upper surface of the rear parcel shelf of a motor vehicle is finally known from FR2421760. The device of FR2421760 comprises an elastic band whose length corresponds substantially to the width of the rear shelf. Each end of the elastic band is mounted securely to a longitudinal edge of the rear shelf by pinching together the elastic band and the longitudinal edge of the rear shelf using a shelf edge clamp and an end section of the elastic band.

[0011] The object-fixing device of FR2421760 is limited in its use to fixing objects to the upper surface of the rear shelf of a motor vehicle. It does not provide for suspending an object in contact with the lower surface of the rear shelf, nor does it provide for such suspension to allow the object to be fixed to the rear shelf in a way that obscures or masks the object from public view.

[0012] The invention aims to overcome these drawbacks.

[0013] In addition, the device for securing objects of FR2421760 requires, for its mounting on the rear shelf of the motor vehicle, access to the longitudinal edges of the rear shelf for the purpose of mounting the strap clamp and the edge of the shelf and therefore to remove the rear shelf from its location in the motor vehicle for this mounting.

[0014] The invention aims in particular to overcome this drawback.

[0015] But the invention also aims to overcome all of these aforementioned disadvantages.

[0016] The invention therefore aims to provide a device for securing at least one object and a rigid rear shelf of a motor vehicle, allowing at least one thin object - and in particular one of low mass - to be secured to said rigid rear shelf.

[0017] The invention also aims to provide such a fastening device which is removable in that it can be easily detached from and / or assembled with the rigid rear shelf without requiring the use of a tool.

[0018] The invention also aims to provide such a fastening device which is removable and movable without requiring extraction of the rigid rear shelf of the motor vehicle.

[0019] The invention also aims to provide such a fastening device which allows at least one object to be fastened to the rigid rear shelf and for such infrequently used objects to be stored.

[0020] The invention also aims to provide such a fastening device which is simple in its use and which allows for the storage of at least one object which is facilitated.

[0021] The invention also aims to provide such a fastening device which has a moderate manufacturing cost and is inexpensive.

[0022] The invention also aims to provide such a fastening device allowing the rigid rear tablet to be fastened to objects of different sizes. Description of the invention

[0023] To this end, the invention relates to a device, called a fastening device, for fastening at least one object and a rigid rear shelf of a motor vehicle, said fastening device comprising: a. a link made of at least one elastic material, b. two hooks, the first hook of which is attached to one of the two ends longitudinal ends of the elastic band and a second hook attached to the other of the two longitudinal ends of the elastic band, each hook being shaped to be able to cooperate with a through opening formed in the rigid rear shelf so that, each hook being engaged in a through opening of the rigid rear shelf, the elastic link in a state of extension - in particular in a state of partial elastic extension - extends into contact with one of the two main faces - in particular into contact with a lower main face - of the rigid rear shelf in the absence of any object interposed between the elastic link and the rigid rear shelf.

[0024] Throughout the text: The terms "rigid rear shelf" and "rigid rear parcel shelf" are equivalent. They refer to a rigid device which, when the rear hatch of a motor vehicle—particularly a sedan—is in the closed position, extends substantially in a horizontal plane above the trunk and allows the contents of the trunk to be concealed or hidden from public view. It should be noted that the two main faces of a rigid rear shelf are accessible by tilting the shelf along a tilting axis parallel to the Y-axis of the motor vehicle. - the terms "front", "rear", "right", "left", "up", "down", "above" and "below" are to be considered in relation to a motor vehicle in a normal driving position, - the XYZ reference frame refers to a direct orthonormal XYZ reference frame classically used in automotive design, in which the X axis designates the front-to-back longitudinal direction of the vehicle, oriented towards the rear, the Y axis designates the transverse direction and is oriented towards the right of the vehicle, the Z axis designates the vertical direction, and is oriented upwards.

[0025] According to certain embodiments, at least one object is a low-mass object. This could be, for example, a sunshade folded like an accordion and used seasonally. It could also be a safety vest or high-visibility vest, possibly folded into a cover. It could also be a safety kit including a warning triangle. Any other low-mass object used occasionally or not can be suspended from the rigid rear shelf by means of the device according to the invention.

[0026] According to the invention, the link in at least one elastic material is an elongated and extensible elastic link at least along the elongation axis of the elastic link.

[0027] The length of the link in at least one elastic material is chosen so that in any state of assembly of the device according to the invention with the rigid rear shelf of the motor vehicle, in which each hook of the device is engaged with a through opening formed in the rigid rear shelf, the elastic link in a state of at least partial extension brings each hook back into the position of the device according to the invention to the rigid rear shelf.

[0028] In particular, the length of the link in at least one elastic material is chosen so that in any state of assembly of the device according to the invention with the rigid rear shelf of the motor vehicle, in which each hook of the device is engaged with a through opening formed in the rigid rear shelf, the elastic link in a state of at least partial extension extends into contact with a main face, in particular the lower main face, of the rigid rear shelf.

[0029] According to certain embodiments, the device according to the invention is a removable device for securing at least one object to a rigid rear shelf of a motor vehicle. A removable device is understood to be a device according to the invention that can be attached to or detached from the rigid rear shelf. In other words, the hooks are reversible fastening means for said securing device and the rigid rear shelf. Furthermore, since each hook of said securing device is removable, each hook can be moved on the rigid rear shelf so as to adapt said securing device to the size of the object to be secured.

[0030] According to the invention, each through opening of the rigid rear shelf opens onto one and the other of the two main faces of the rigid rear shelf.

[0031] In some embodiments, the elastic band is made of at least one elastic textile. In some embodiments, at least one elastic textile is an elastic polyurethane. In these embodiments, the elastic textile is robust and the perceived quality of the motor vehicle is ensured. In some embodiments, the elastic band is formed of a single strand of at least one elastic material. In some embodiments, the elastic band is formed of a plurality of strands, each strand being made of at least one elastic material.

[0032] According to certain embodiments, each hook is a U-shaped hook having: a. a first arm, called the link arm, intended to extend opposite a first main face of the rigid rear shelf, the free end of said link arm being connected to a first longitudinal end of the elastic link, and b. a second branch, called the opposite branch, intended to extend opposite a second main face of the rigid rear tablet, opposite the first main face.

[0033] According to certain embodiments, the first main face of the rear rigid shelf is a lower face of the rear rigid shelf. According to these embodiments, the second main face of the rear rigid shelf is a upper face of the rear rigid shelf. According to these embodiments, said connecting arm extends opposite the lower face of the rear rigid shelf and said opposite connecting arm extends opposite the upper face of the rear rigid shelf.

[0034] The lower principal face of the rear rigid shelf is the principal face of the rear rigid shelf oriented downwards (along the -Z direction of the right-handed orthonormal coordinate system) and extending towards the trunk of the motor vehicle when the rear rigid shelf is folded down to obstruct the trunk. The upper principal face of the rear rigid shelf is the principal face of the rear rigid shelf oriented upwards (along the +Z direction of the right-handed orthonormal coordinate system) and visible to a person outside the motor vehicle when the rear rigid shelf is folded down to close the trunk.

[0035] However, nothing prevents the first main face of the rear rigid shelf from being, according to certain embodiments, an upper face of the rear rigid shelf. According to these embodiments, the second main face of the rear rigid shelf is a lower face of the rear rigid shelf. According to these embodiments, said connecting branch extends opposite the upper face of the rear rigid shelf and said opposite branch extends opposite the lower face of the rear rigid shelf.

[0036] According to certain advantageous embodiments, said connecting branch and said opposite branch of at least one—in particular of each—U-hook are coplanar. According to certain embodiments, said connecting branch and said opposite branch extend along axes that are substantially parallel to each other. According to certain advantageous embodiments, said connecting branch and said opposite branch of at least one—in particular of each—U-hook are parallel. According to these embodiments, the plane comprising said connecting branch and said opposite branch of at least one U-hook—in particular of each U-hook—is orthogonal to the plane of the rear rigid shelf when the U-hook is assembled with the rear rigid shelf.

[0037] According to certain embodiments, at least one—in particular each—U-hook has a connecting section between said connecting arm and said opposite arm, the connecting section being rounded and extending substantially in the same plane as said connecting arm and said opposite arm. This facilitates the tilting engagement of the U-hook in the through opening of the rigid rear shelf.

[0038] In certain embodiments, at least one—in particular each—U-hook is formed of at least one polymer or plastic material, for example, polyoxymethylene (POM). In certain embodiments, at least one—in particular each—U-hook is formed of at least one rigid material, i.e., substantially non-deformable. However, nothing prevents the provision that, in certain embodiments, said connecting arm and said opposite arm of at least one—in particular each—U-hook are shaped so as to be elastically brought towards each other in a transverse clamping position of the rigid rear shelf. In these embodiments, said U-hook is held at least partially by clamping the rigid rear shelf.

[0039] According to certain embodiments, each of said link branch and said opposite branch has a thickness between 1 mm and 2 mm.

[0040] According to certain advantageous embodiments, the elastic link extends in line with said link arm. In these advantageous embodiments, said link arm does not form an additional thickness relative to the elastic link, so that, in the absence of any object interposed between the elastic link and the rear rigid shelf, the elastic link, in a state of at least partial extension, extends into contact with said first main face—in particular, the lower main face—of the rear rigid shelf.

[0041] In some embodiments, the connecting arm of each U-hook has a grasping appendage for the U-hook. In some embodiments, the connecting arm, the opposing arm, and the grasping appendage for the U-hook are substantially coplanar. In some embodiments, the grasping appendage is an elongated grasping appendage extending substantially orthogonally to the connecting arm. Grasping each U-hook and manipulating it to insert the opposing arm into a through opening in the rigid rear shelf is facilitated.

[0042] In some embodiments, the gripping appendage has a curved free end. In some embodiments, the curved free end of the gripping appendage is adapted to allow the suspension of a light object and / or the holding of a container in a vertical position in the trunk of a motor vehicle.

[0043] According to some embodiments, each U-hook is a U-profile and the elastic link is a strap, each U-profile forming: a. a first plate, called the strap plate, intended to extend opposite the first main face of the rigid rear shelf, one free end of said strap plate being connected to one of the two longitudinal ends of the strap, and b. a second plate, called the opposite plate, intended to extend opposite the second main face of the rigid rear shelf, opposite the first main face.

[0044] According to certain embodiments, said strap plate and said opposite plate extend in planes substantially parallel to each other.

[0045] According to some embodiments, each of said strap plate and said opposite plate has a thickness between 1 mm and 2 mm.

[0046] According to certain advantageous embodiments, the strap extends in line with said strap plate. In these advantageous embodiments, said strap plate does not form a raised thickness relative to the strap so that, in the absence of any object interposed between the strap and the rigid rear shelf, the strap in a partially extended state extends in contact with said first main face - in particular a lower main face - of the rigid rear shelf.

[0047] According to certain embodiments, at least one—in particular each—U-profile has a profile base forming a connection between said strap plate and said opposing plate, the profile base having, in any cross-section of the U-profile in a plane orthogonal to the planes of said strap plate and said opposing plate and parallel to the axis of elongation of the strap, a rounded shape. The engagement of the U-profile by tilting into the through opening of the rigid rear shelf is thus facilitated. The installation and removal of each U-profile are also facilitated.

[0048] In certain embodiments, the webbing plate and the opposing plate of the U-profile are of the same width. The terms "width of the webbing plate," "width of the opposing plate," and "width of the U-profile" refer to the dimensions of the webbing plate, the opposing plate, and the U-profile extending along the longitudinal axis of the U-profile (an axis parallel to the Y-axis of the XYZ coordinate system). In certain embodiments, the U-profile has a width between 10 mm and 24 mm, preferably between 20 mm and 24 mm, and in particular approximately 22 mm. In these embodiments, since each through-opening formed in the rigid rear shelf is a slot extending longitudinally along the Y-axis of the coordinate system, each slot formed in the rigid rear shelf has a length of approximately 25 mm. The mechanical strength properties of the rigid rear shelf are maintained.

[0049] According to certain embodiments, each U-shaped profile is formed from a single piece, in one piece.

[0050] In these embodiments, the U-shaped profile forms an overlapping receiving groove with a thickness equal to that of the rigid rear shelf. According to some embodiments, the thickness of the rigid shelf is between approximately 4 mm and of the order of 5 mm, said strap plate and said opposite plate are separated by less than 10 mm, or less than 9 mm, or less than 8 mm, or less than 7 mm.

[0051] In certain embodiments, the opposing plate and the strap plate each have a length along an axis of elongation of the strap, the length of the opposing plate being substantially equal to the length of the strap plate. In these embodiments, the strap plate and the opposing plate are substantially the same size along an axis parallel to the axis of elongation of the strap. The engagement of the opposing plate of the U-profile in the through slot of the rigid rear shelf and the pivoting of the U-profile so as to bring the opposing plate into contact with and substantially parallel to the rigid rear shelf is facilitated. However, nothing prevents the opposing plate from having, in other embodiments, a dimension along the axis of elongation of the strap greater than a dimension of the strap plate along the axis of elongation of the strap.The engagement of said opposite plate of the U-profile in the through slot of the rigid rear shelf and the pivoting of the U-profile so as to bring said opposite plate into contact and substantially parallel to the rigid rear shelf is facilitated.

[0052] According to certain embodiments, said strap plate and said opposite plate are linked together by a rounded profile bottom facilitating the engagement of said opposite plate of the U-profile in the through slot of the rigid rear shelf and the pivoting of the U-profile.

[0053] The engagement of said opposite plate of the U-profile in the through slot of the rigid rear shelf and the pivoting of the U-profile is facilitated at least by the fact of the smaller length of said strap plate and / or the rounded bottom of the profile.

[0054] In certain embodiments, at least one—in particular each—U-profile is formed of at least one rigid material, i.e., substantially non-deformable. In certain embodiments, however, nothing prevents the strap plate and the opposing plate of at least one—in particular each—U-profile from being shaped so as to be elastically brought towards each other in a transverse clamping position of the rear rigid shelf. In these embodiments, the U-profile is held at least partially by clamping the rear rigid shelf.

[0055] According to some embodiments, the strap and said strap plate are substantially of the same width.

[0056] According to some embodiments, said opposite plate has a width less than the length of the through slot of the rigid rear shelf with which it cooperates.

[0057] According to certain embodiments, the free end of said webbing plate of the U-profile has a transverse slot for securing the U-profile and the webbing by stitching the webbing to itself. In this embodiment, the transverse slot of said webbing plate is traversed by a longitudinal end of the webbing, the longitudinal end of the webbing being folded into a loop upon itself and stitched into a loop onto the webbing.

[0058] In certain embodiments, the strap plate is provided with a gripping appendage. This facilitates gripping each U-shaped profile and manipulating it to insert the opposing plate into a through slot in the rigid rear shelf. In certain embodiments, the gripping appendage has a curved free end. In certain embodiments, the curved free end of the gripping appendage is adapted to allow the suspension of a light object and / or the holding of a container in a vertical position in the trunk of the motor vehicle.

[0059] The invention extends to a rigid rear shelf of a motor vehicle, the rigid rear shelf having: - at least one set of at least two through openings, and - at least one mechanism, called a solidarity mechanism, to foster solidarity less one object and the rigid rear shelf of the motor vehicle according to the invention, said at least one securing device comprising: a. a link made of at least one elastic material, b. Two hooks, one hook being attached to one of the two longitudinal ends of the elastic link, and the other hook being attached to the other of the two longitudinal ends of the elastic link, each hook being shaped to cooperate with a through opening formed in the rear rigid shelf such that, with each hook engaged in a through opening of the rear rigid shelf, the elastic link, in a state of at least partial extension, extends into contact with a principal face—in particular, a lower principal face—of the rear rigid shelf in the absence of any object interposed between the elastic link and the rear rigid shelf.

[0060] According to the invention, each through opening of the set of openings opens onto one and the other of the two main faces of the rigid rear shelf.

[0061] According to some embodiments, the material forming the rigid rear shelf has a thickness of between the order of 1 mm and the order of 10 mm, in particular between the order of 4 mm and the order of 5 mm.

[0062] According to certain preferred embodiments, the elastic link of at least one fastening device extends to contact a lower principal face of the rear rigid shelf, the lower principal face of the rear rigid shelf being the main face intended to be able to extend in relation to the trunk of the motor vehicle.

[0063] According to certain embodiments, each through opening is a through slot, each elastic link is a strap made of elastic material, and each hook is a U-profile having: a. a first plate, called the strap plate, intended to extend opposite the underside of the rigid rear shelf, the free end of said strap plate being connected to a first longitudinal end of the strap, and b. a second plate, called the upper plate, extending opposite the upper face of the rigid rear shelf, each U-profile being shaped to cooperate with a through slot formed in the rigid rear shelf so that, each U-profile being engaged in a through slot, the strap in a state of at least partial extension extends into contact with an underside of the rigid rear shelf.

[0064] According to certain embodiments, the rigid rear shelf has three sets of three through slots, the through slots of each set being parallel to each other and substantially aligned along the X-axis of the motor vehicle, the sets of through slots being distributed laterally along the Y-axis of the motor vehicle, the X and Y axes being defined according to a direct orthonormal XYZ coordinate system commonly used in automotive design. The rigidity of the rigid rear shelf is not substantially affected.

[0065] The invention also extends to a motor vehicle equipped with a rigid rear shelf according to the invention. Thus, the invention makes it possible to store lightweight object(s)—particularly object(s) of infrequent use—in the motor vehicle, the object(s) remaining accessible within the vehicle but concealed and hidden from public view. The risk of theft is therefore reduced. Brief description of the drawings

[0073] The rigid rear shelf 3 of a motor vehicle according to the invention, viewed from below and in [Fig. 1], has a flat base 23 with three sets 25, 26, 27 of through slots 7 opening onto the two main faces 8, 9 of the rigid rear shelf 3. The through slots 7 of each set 25, 26, 27 are parallel to each other and parallel to the Y-axis of the direct orthonormal coordinate system XYZ (as shown in [Fig. 6]) and are substantially the same length along this same Y-axis. In the embodiment shown, each through slot 7 has a length between 10 mm and 35 mm, for example, approximately 25 mm. The through slots 7 of each set 25, 26, 27 are aligned with respect to the X-axis of the direct orthonormal coordinate system. Thus the sets 25,26,27 of slots are parallel to each other, each set 25,26,27 of slots including a rear through slot 7 (at the top on the [Fig.l]), a front through slot 7 (at the bottom in [Fig. 1]) and an intermediate through slot 7 along the X-axis of the direct orthonormal coordinate system. In the embodiment shown, a left-hand set 25 of slots is the leftmost set of slots. Two rear and intermediate slots 7 of the left-hand set 25 of slots cooperate with a fastening device 1 according to the invention and each receives a hook 5, 6 of said fastening device 1. Thus, in the absence of an object to be fastened to the rear rigid shelf 3, the elastic material link 4, 24 elastically pulls the hooks 5, 6 towards each other and maintains said fastening device 1 attached to the rear rigid shelf 3. In the embodiment shown in [Fig. 1], a right-hand set 27 of slots is the rightmost set of slots.Two through slots 7, one at the front and one at the rear of the assembly 27, cooperate with a second fastening device 1 according to the invention and each receives a hook 5, 6 of said fastening device 1. Thus, in the absence of an object to be fastened to the rigid rear shelf 3, the elastic material link 4, 24 elastically pulls the hooks back. 5,6” towards each other and maintains said fastening device 1” attached to the rigid rear shelf 3. In the embodiment shown in [Fig. 1], a central set 26 of slots is the set of slots positioned between the right and left sets 25. Two through slots 7, rear and front, of the central set 26 of slots cooperate with a third fastening device 1' according to the invention and each receives a hook 5',6' of said fastening device 1'. Thus, in the absence of an object to be fastened to the rigid rear shelf 3, the elastic material link 4,24 elastically pulls the hooks 5,6 towards each other and maintains said fastening device 1' attached to the rigid rear shelf 3. In the embodiment shown, each elastic link 4 is a strap 24 having an elongation axis 19 substantially parallel to the X-axis of the orthonormal coordinate system. direct.However, nothing prevents us from planning that the slots of the same set 25, 26, 27 of slots are arranged in such a way that the axis 19 of elongation of the strap 24 intersects the X axis of the direct orthonormal frame.

[0074] Figure 2 is a schematic cross-sectional representation in a vertical plane comprising an axis parallel to the X-axis and an axis parallel to the Z-axis of the direct orthonormal coordinate system, and a rigid rear shelf 3 equipped with a device 1 according to the invention adapted to allow an object to be secured to the rigid rear shelf 3. In the embodiment shown in [Fig. 2], no object is secured to the rigid rear shelf 3. In the embodiment shown in [Fig. 2], the bottom 23 of the rigid rear shelf 3 is substantially horizontal, with the rigid rear shelf 3 in the folded position. The rigid rear shelf 3 has three through slots 7 opening onto the two main faces 8, 9 of the rigid rear shelf 3. Two of the through slots 7, the rear and intermediate ones, of the rigid rear shelf 3 cooperate with a securing device 1 according to the invention, while the through slot 7, the front one, is free and does not cooperate with the securing device 1.The fastening device 1 comprises a first hook 5 adapted to engage with a first slot 7 through the rigid rear shelf 3 and to overlap a thickness 23 of the rigid rear shelf 3's base. The first hook 5 is U-shaped. The U-shaped profile 5 is adapted and dimensioned to engage with a slot 7 through the rigid rear shelf 3 and to overlap a thickness 23 of the rigid rear shelf 3's base. The U-shaped profile 5 forms a first plate, referred to as the strap plate 20, intended to extend opposite the first main face 8 of the rigid rear shelf 3, in particular opposite the lower main face 8 of the rigid rear shelf 3. A free end 12 of the strap plate 20 is connected to a longitudinal end 17 of the strap 24.This connection can be made by any suitable means, allowing the strap 24 to remain extended in contact with the rigid rear tablet 3 in the absence of an object. interposed between the rigid rear shelf 3 and the strap 24. As illustrated in [Fig. 3], this bridge connection is made by stitching. The first U-shaped profile 5 also forms a second plate, called the opposite plate 21, substantially parallel to the strap plate 20 and extending at a distance from the strap plate 20.
