Description

Title of the invention: Trunk floor arrangement for motor vehicle

[0001] The technical context of the present invention is that of motor vehicles, and more particularly of motor vehicle trunk arrangements. More specifically, the invention relates to a trunk floor arrangement for a motor vehicle.

[0002] In the prior art, document DE19739092 discloses vehicle trunk fittings comprising a mounting rail fixed to the vehicle floor and serving as a fastening element for a trunk mat. The mounting rail is first fixed to the vehicle floor with screws, and then the trunk mat is inserted into a groove formed on the mounting rail and is removably secured in the rail by pinching. The trunk mat thus covers the trunk floor while being correctly positioned relative to the surrounding walls. The trunk mat can be removed by the user by pulling it in the opposite direction to that in which it was inserted into the mounting rail.

[0003] The drawback of this vehicle trunk arrangement is that the mounting rail is always visible and cannot be removed by the user to increase the trunk volume. Even if the user were to unscrew the mounting rail, the trunk mat would no longer be secured. If the user wishes to remove the trunk mat to increase the trunk volume, they would not be able to bypass this mounting rail, which protrudes from the vehicle floor. Another drawback of this vehicle trunk arrangement is that the trunk mat is insufficiently secured against stress applied in the opposite direction to that of insertion into the mounting rail. Furthermore, this trunk arrangement does not offer a solution for securing the mat under the seat.

[0004] The under-seat mat and the trunk mat are directly used by the user; therefore, they must be securely attached to the vehicle floor. Furthermore, it is important to provide a solution that allows the user to increase the trunk volume without any protruding objects and without compromising the attachment of the trunk mat and, if present, the under-seat mat.

[0005] The present invention aims to propose a new trunk arrangement in order to address at least largely the previous problems and to lead to other advantages.

[0006] Another object of the invention is to propose a vehicle trunk layout that is configured to limit the number of operations required for its assembly, so as to optimize the production time of said automotive vehicle trunk arrangement.

[0007] Another object of the invention is to propose a vehicle trunk arrangement that is universal and configured to adapt to different motor vehicles.

[0008] Another object of the invention is to propose a simple motor vehicle trunk arrangement, both from the point of view of its implementation, and from the point of view of its manufacture.

[0009] Another object of the invention is to propose a motor vehicle boot arrangement that is inexpensive, so as to limit the cost of such a motor vehicle boot arrangement compared to existing motor vehicle boot arrangements.

[0010] Another object of the invention is to propose a space-saving motor vehicle trunk arrangement, guaranteeing the compactness and lightness of the motor vehicle.

[0011] According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with a boot floor arrangement for a motor vehicle, the boot floor arrangement comprising a carpet support in the form of a prismatic span extending longitudinally and comprising at least one fixing housing; a boot soundproofing element intended to form a floor of a boot of the motor vehicle, the boot soundproofing element comprising an end flap comprising at least one light located opposite at least one fixing housing; at least one fixing member engaged through at least one light of the boot soundproofing element and collaborating by engagement of complementary shapes with at least one fixing housing.

[0012] Such a trunk base arrangement therefore allows correct indexing of the trunk soundproofing element, adequate fixing resistant to any stress, and prevents any acoustic leakage.

[0013] Such a trunk floor arrangement allows the trunk soundproofing element to be secured robustly, enabling it to withstand any stress exerted in any direction, while ensuring correct positioning, i.e., indexing, of the soundproofing element relative to the walls defining the trunk of the motor vehicle. Correct positioning means that the trunk soundproofing element covers the floor of the motor vehicle without forming creases and, if necessary, without leaving any part of the trunk floor visible.

[0014] In the chest bottom arrangement according to the first aspect of the invention, the prismatic span is of elongated parallelepiped shape.

[0015] The safe arrangement according to the first aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:

[0016] - at least one fixing housing is a blind cavity formed in the support of carpet ;

[0017] - the trunk soundproofing element comprises a soundproofing material, such as for example felt or foam;

[0018] - the trunk soundproofing element includes a shaped arrangement for accommodate a spare wheel;

[0019] - When the carpet support has a single fixing housing, then The trunk soundproofing element has a single light located opposite the fixing housing, the trunk floor arrangement having a single fixing element engaged through the light and in the fixing housing.

[0020] - When the carpet support has a plurality of fixing slots, then the trunk soundproofing element has a plurality of lights, each light being located opposite one of the fixing slots, the trunk floor arrangement having a plurality of fixing devices, each fixing device being engaged through one of the lights and in one of the indexing slots.

[0021] - When the carpet support has a plurality of indexing slots, The indexing slots are then distributed longitudinally along the prismatic span, preferably regularly spaced, with a constant distance between two indexing slots. If the carpet support has a plurality of indexing slots, the indexing slots are preferably aligned.

[0022] - When the carpet support has a plurality of indexing slots, then The lights of the soundproofing element in the trunk are distributed longitudinally along the prismatic span, preferably evenly spaced, with a constant distance between any two lights. Preferably, this constant is equal to the constant distance between any two mounting holes. When the carpet support has a plurality of indexing holes, the lights are preferably aligned.

[0023] - The trunk floor arrangement includes an under-seat mat intended to be placed under seats of the motor vehicle, the under-seat mat having a section overlapping or being covered by the terminal flap of the trunk soundproofing element, the section of the under-seat mat having at least one opening located opposite at least one light of the trunk soundproofing element.

[0024] - The under-seat mat is intended to be placed under rear seats.

[0025] - When the carpet support has a single fixing housing, then the carpet The sub-seat has a single opening located opposite the light of the trunk soundproofing element, so that the single fixing device is simultaneously engaged in the fixing housing, through the light and the opening.

[0026] - When the carpet support has a plurality of fixing slots, then The under-seat mat has a plurality of openings, each opening being located opposite one of the lights of the trunk soundproofing element, so that each fixing device is simultaneously engaged in one of the indexing housings and through one of the lights and one of the openings.

[0027] - When the carpet support has a plurality of indexing slots, The openings are then distributed longitudinally along the edge of the carpet under the seat, preferably regularly spaced, with a constant distance between any two openings. Preferably, this constant distance is equal to the constant distance between any two fixing points. When the carpet support has multiple fixing points, the openings are preferably aligned.

[0028] - Each at least one fastening element is formed by a pin. Such a pin is mounted in a removable manner in its dedicated mounting housing.

[0029] - The pawn is of the type of a Christmas tree clip. Such a pawn makes it possible to maintain a surface substantially flat on its surface, allowing objects to slide over it.

[0030] - Preferably, the safe-bottom arrangement comprises three compartments of three fixing points in the carpet support, three lights in the trunk soundproofing element, three openings in the under-seat carpet, and three fixing devices. When the three fixing points, the three lights, and the three openings are vertically aligned, they define three spaces into which the three fixing devices are inserted.

[0031] - The trunk floor arrangement includes a trunk floor trim comprising at least one retaining finger configured to work with at least one mounting slot of the carpet support, each at least one retaining finger of the trunk floor trim forming at least one retaining element. Such a retaining finger is removable and mounted in its dedicated mounting slot. This trunk floor arrangement provides a means of retaining the trunk soundproofing element and the under-seat carpet when the user temporarily removes the trunk floor trim from their vehicle to obtain a larger cargo volume. Furthermore, the removable trunk floor trim ensures the user has no protruding elements in the trunk, facilitating the loading and loading of items to be transported.Replacing the boot floor trim, i.e. the fixing fingers, with a removable fixing element also prevents leaving . A visible edge of material is used to ensure a satisfactory aesthetic result, while also providing resistance to any stress exerted on the trunk soundproofing element and the under-seat carpet. In other words, the presence of one or more fasteners prevents the trunk soundproofing element and the under-seat carpet from coming loose from the stack on the carpet support, thus preventing any risk of a visible edge of material (usually white) that would detract from the aesthetic quality if it were visible in this generally dark area of ​​the trunk. When reinstalling the trunk floor trim, the user will remove the fasteners from their mounting points and then reinstall the trunk floor trim, aligning the fastener clips with the mounting points.

[0032] - The end flap of the trunk soundproofing element is located in a position intermediate between the carpet support and the boot floor trim, each at least one boot floor trim fixing finger passing through one of at least one light of the boot soundproofing element and collaborating with one of at least one fixing housing of the carpet support.

[0033] - The section of the under-seat carpet is located in an intermediate position between the carpet support and trunk floor trim, each with at least one trunk floor trim fixing finger passing through at least one opening in the under-seat carpet and collaborating with at least one fixing housing of the carpet support.

[0034] According to a second aspect of the invention, a motor vehicle is proposed comprising a trunk located behind the seats of the motor vehicle, the motor vehicle comprising a trunk floor arrangement according to the first aspect of the invention or according to any of its improvements, the trunk floor arrangement delimiting a front edge of the trunk.

[0035] In the motor vehicle according to the second aspect of the invention, the trunk is located behind the rear seats of the motor vehicle.

[0036] In the motor vehicle according to the second aspect of the invention, the trunk floor arrangement according to the first aspect of the invention or according to any of its improvements comprises a carpet support attached to the motor vehicle. The carpet support is attached to the body structure of the motor vehicle by two fasteners. These fasteners may be screws, nuts, clips, or any other fastening means allowing the carpet support to be retained to the body structure. The fasteners are arranged on a lower flap of the carpet support. The lower flap is not located in the same vertical plane as the upper face. Viewed from above, the fasteners are regularly offset, or staggered, with respect to the mounting slots.

[0037] In the motor vehicle according to the second aspect of the invention, the trunk floor arrangement according to the first aspect of the invention or according to any of its improvements includes a carpet support fixed to the motor vehicle such that the main axis of extension of the carpet support is perpendicular to the axis of advancement of the motor vehicle.

[0038] Various embodiments of the invention are provided, incorporating, according to all their possible combinations, the different optional features set out here.

[0039] Other features and advantages of the invention will become apparent from the following description on the one hand, and from several illustrative and non-limiting examples of embodiments given with reference to the accompanying schematic drawings on the other hand, in which:

[0047] [Fig.8] illustrates a cross-sectional view of the boot floor arrangement of a motor vehicle illustrated in [Fig.7], the section being made at the right of a fastening element.

[0048] Of course, the features, variants and different embodiments of the invention can be combined with each other in various ways, provided they are not incompatible or mutually exclusive. of others. In particular, one can imagine variants of the invention comprising only a selection of features described subsequently in isolation from the other features described, if this selection of features is sufficient to confer a technical advantage or to differentiate the invention from the prior art.

[0049] In particular, all the variants and embodiments described are combinable with each other if there is no technical obstacle to this combination.

[0050] In the figures, the elements common to several figures retain the same reference.

[0051] Figure 1 shows a motor vehicle 1 conforming to the second aspect of the invention, seen from the side. Figure 1 shows a motor vehicle 1 comprising a trunk 2 in which is arranged the trunk floor arrangement 3 according to the invention, indicated by transparency with dotted lines.

[0052] For this [Fig. 1] only, illustrating the arrangement of the trunk floor 3 mounted in the trunk 2 of the motor vehicle 1, a frame of reference comprising an axis xl, an axis yl, and a vertical axis z is defined. The axis xl corresponds to the trajectory of the motor vehicle 1 when it is moving forward, in a straight line, and on a flat road. The axis xl corresponds to a direction from the rear to the front of the motor vehicle 1, and it is oriented from the rear to the front of the motor vehicle 1. The axis yl corresponds to the axis around which the wheels of the motor vehicle 1 rotate, and the direction of the axis yl is oriented from the driver's side to the passenger's side, in the non-Anglo-Saxon standard. The vertical axis z is an axis perpendicular simultaneously to the axes xl and yl and is oriented from the floor of the motor vehicle 1 to its roof or parallel to gravity and oriented in the opposite direction to it.

[0053] Thus, the trunk 2 is located behind the rear seats 4 of the motor vehicle 1, along axis xl. Of course, the invention can also be fitted to motor vehicles 1 comprising only front seats 5; in this case, the trunk 2 is located behind the front seats 5, along axis xl. The trunk 2 is accessible via a tailgate 2a, with the user positioning themselves at the rear of the motor vehicle 1 to access the trunk 2. In this configuration, a front edge of the trunk 2 is defined as being closest to the tailgate 2a, and a trunk floor 2 is defined as being closest to the seats 4, 5. The trunk floor arrangement 3 is therefore delimited by the front edge and the floor of the trunk 2. The trunk 2 of the motor vehicle 1 conforming to the second aspect of the invention is also delimited laterally by side walls 6 of the trunk 2. The side walls 6, the front edge, and the trunk floor then define the volume of the trunk 2.

[0054] Note: The trunk soundproofing, trunk mat support, and under-seat mat are fitted in all types in the vehicle when present. Only the trunk floor trim is removable. However, when the floor arrangement of Trunk 3 is not mounted in the trunk 2 of motor vehicle 1; the latter has its own frame of reference, corresponding to a 90° rotation in the xlyl plane relative to its mounting position in trunk 2. Therefore, for the remainder of this description, we define a frame of reference in which the previously defined axes xl and yl are reversed to define a longitudinal axis x corresponding to the principal elongation axis of the carpet support and a transverse axis y corresponding to the principal elongation axis of the soundproofing element from the carpet support. The vertical axis z always corresponds to an axis parallel to gravity and oriented in the opposite direction. We also define a longitudinal direction parallel to the longitudinal axis x, and the adjectives "along" or "length" refer to this reference direction.We also define a transverse direction parallel to the transverse y-axis, and the adjectives "lateral" or "transverse" refer to this reference direction. We also define a vertical direction parallel to the vertical z-axis, and the adjectives "superior", "inferior", "above", "below" refer to this reference direction.

[0055] Figure 2 shows a trunk floor arrangement 3 for a motor vehicle 1 according to the first aspect of the invention. The trunk floor arrangement 3 comprises a carpet support 7 in the form of a prismatic span, extending longitudinally along the longitudinal axis x. In other words, the carpet support 7 has a direction of extension parallel to the longitudinal axis x. By prismatic span, we mean an elongated parallelepiped shape, for example, in the form of a beam. Generally, the carpet support 7 is an injection-molded plastic part, or the carpet support 7 may be made of expanded polypropylene.

[0056] The carpet support 7 is delimited by at least six faces, four lateral faces and two end faces 72. Among the lateral faces 71, a flat upper face 73 is distinguished in which one or more fixing housings 70 are provided. More precisely, the carpet support 7 illustrated comprises three fixing housings 70 distributed uniformly along the upper face 73, i.e. along the longitudinal axis x, being aligned with each other.

[0057] The mounting housing 70 is in the form of a cavity formed inside the carpet support 7, from the upper face 73. Preferably, the cavity forming the mounting housing 70 is blind, i.e., it does not open onto another face 71, 72 of the carpet support 7. The mounting housing 70 provides a mounting location for the other elements constituting the trunk floor arrangement 3 and also allows indexing of all these elements to ensure their correct positioning in the motor vehicle 1.

[0058] The boot floor arrangement 3 for a motor vehicle 1 includes a boot soundproofing element 8 intended to cover the boot floor 2 of the vehicle automobile 1, thus forming a kind of boot mat. The boot soundproofing element 8 extends longitudinally from the mat support 7 and is intended to extend transversely to the front edge of the boot 2 as well as laterally to the side walls 6 of the boot 2.

[0059] The trunk soundproofing element 8 comprises an end flap 83 for covering the carpet support 7 and a portion 81 providing soundproofing to reduce noise from underbody components, i.e., those located beneath the trunk floor 2. To perform its function, the trunk soundproofing element 8 is made, for example, of felt or foam or any other noise-reducing material. The soundproofing element has a thickness of approximately 5 centimeters in its portion 81 providing soundproofing.

[0060] It should be noted that the terminal flap 83 has a reduced thickness compared to the part 81 providing soundproofing, in order to facilitate its deformation to best fit the shape of the carpet support 7, to facilitate its attachment to the carpet support 7 and to limit the bulk in this attachment area.

[0061] Depending on the model of motor vehicle 1, depending on the presence or absence of a spare wheel, the trunk soundproofing element 8 can be equipped with a fitting 82 allowing access to this spare wheel placed on the trunk floor soundproofing element 8. Of course, it is possible to provide a trunk soundproofing element 8 that is completely solid in its part 81 ensuring soundproofing and therefore not including the fitting 82.

[0062] The end flap 83 is intended to cover the upper face 73 of the carpet support 7. The end flap 83 includes at least one light 80 located opposite at least one of the fixing slots 70. More precisely, the end flap 83 includes as many lights 80 as there are fixing slots 70 and the lights are distributed in the same way in order to cooperate with the fixing slots 70 of the carpet support 2. In other words, each light 80 of the end flap 83 is intended to be opposite the fixing slot 70, which is dedicated to it.

[0063] The boot floor arrangement 3 for motor vehicle 1 includes one or more fastening members 9, each engaged through one of the lights 80 of the boot soundproofing element 8 and collaborating by engaging complementary shapes with the fastening housing 70, which is associated with it.

[0064] Fig. 3 shows a cross-section of the boot floor arrangement 3 for a motor vehicle 1 conforming to the first aspect of the invention, the straight section passes through the centre of one of the fixing members 9 passing through the terminal flap 83 of the boot soundproofing element 8 and the fixing housing 70 of the carpet support 7.

[0065] The fastening member 9 passes through the entire thickness of the terminal flap 83, through the opening 80, and is fixed in the fastening housing 70, so as to maintain The soundproofing element 8 and the carpet support 7 are assembled together. The fastener 9 is attached to the mounting housing 70 either by formwork or by screwing. In the case of screwing, the mounting housing 70 is provided with a thread that complements the fastener 9.

[0066] The fastener 9 is a pin, a screw, or a protruding element formed from another part of the trunk floor assembly 3, as will be described later. In the illustrated example, the fastener 9 is formed by a pin of the type of a fir tree clip. Of course, the fastener 9 can take various forms as long as its fastening function is ensured.

[0067] The fastening member 9 is removable, in the sense that a user can unscrew it or remove it from the fastening housing 70 to detach the trunk soundproofing element 8 from the carpet support 7. The fastening provided by the fastening member 9 allows the trunk soundproofing element 8 to be fixed in a robust manner, enabling it to withstand any stress exerted in any direction, while ensuring correct positioning, i.e. indexing, of the soundproofing element 8 with respect to the walls defining the trunk 2 of the motor vehicle 1.

[0068] It is understood that, when the carpet support 7 has a single fixing housing 70, then the trunk soundproofing element 8 has a single light 80 located opposite the fixing housing 70, and that the trunk floor arrangement 3 then has a single fixing member 9 engaged through the light 80 and the fixing housing 70. In the case where the carpet support 7 has a plurality of fixing housings 70, then the trunk soundproofing element 8 has a plurality of lights 80, each light 80 being located opposite one of the fixing housings 7, the trunk floor arrangement 3 having a plurality of fixing members 9, each fixing member 9 being engaged through one of the lights 80 and in one of the fixing housings.

[0069] In the case where the carpet support 7 has a plurality of mounting holes 70, then the mounting holes 70 are distributed longitudinally along the carpet support 7, that is, along the prismatic span, along the longitudinal axis x. The mounting holes 70 are preferably regularly distributed, that is, a distance D between any two mounting holes 70 is constant. In the case where the carpet support 7 has a plurality of mounting holes 70, it is also preferable that the mounting holes 70 be aligned with each other along the longitudinal axis x.

[0070] Similarly, in the case where the end flap 83 has a plurality of lights 80, then the lights 80 are distributed longitudinally along the end flap 83, that is, along the longitudinal axis x. The lights 80 are preferentially regularly distributed, that is to say, a distance D between two lights 80 is constant, this constant being equal to the constant D separating two adjacent fixing housings 70. In the case where the end flap 83 has a plurality of lights 80, it is also preferable that the lights 80 be aligned with each other along the longitudinal axis x.

[0071] The carpet support 7, visible in [Fig. 4], is attached to the body structure 100 of the motor vehicle 1 by two fasteners 74. These fasteners 74 may be screws, nuts, clips, or any other fastening means allowing the carpet support 7 to be retained on the body structure 100. The fasteners 74 are arranged on a lower flap 75 of the carpet support 7. The lower flap 75 is not located in the same vertical plane as the upper face 73.

[0072] It should be noted that, viewed from above, the fastening elements 74 are regularly offset, or staggered, with respect to the fastening slots 70. In the illustrated example, the carpet support 7 comprises three fastening slots 70 regularly distributed and aligned along the upper face 73. More precisely, two adjacent fastening slots 70 are separated by a distance D. The carpet support 7 comprises two fastening elements 74 aligned along the lower flap 75 and separated by a distance D. In projection, the fastening elements 74 are located at a distance D / 2 from the fastening slots 70. This arrangement ensures a balanced distribution of forces, particularly when the elements attached to the carpet support 7 are under load.Of course, there are other possibilities for best distributing the forces applied to the carpet support 7, and this particular example is not intended to be a limiting example of the invention.

[0073] In the illustrated example, the positioning of the carpet support 7 relative to the motor vehicle 1 is such that the principal axis of extension x of the carpet support is perpendicular to the axis of advancement xl of the motor vehicle 1.

[0074] Figure 5 shows an example of an alternative embodiment, in which the trunk floor arrangement 3 includes an under-seat mat 10 intended to be placed under the seats 4, 5 of the motor vehicle 1. Preferably, the under-seat mat 10 is intended to be placed under the rear seats 4 of the motor vehicle 1.

[0075] The under-seat mat 10 has a sound-absorbing material on its underside, i.e., on the part that comes into contact with the floor of the motor vehicle 1, and provides an acoustic function. On its front side, the under-seat mat 10 has carpet, i.e., on its surface directly visible to the user.

[0076] The under-seat mat 10 includes a section 11 that overlaps the end flap 83 of the trunk soundproofing element 8 or is covered by the end flap 83. In the example illustrated in [Fig. 5], the section 11 covers the end flap 83. In all cases, the section 11 of the under-seat mat 10 covers the mat support 7 and in particular The upper face 73 of the carpet support 7. Overlapping the trunk soundproofing element 8 and the under-seat carpet 10 on the carpet support 7 prevents any sound leakage. Sound leakage could be detrimental to user comfort.

[0077] The panel 11 of the under-seat carpet 10 includes one or more screws 12, each located opposite one of the lights 80 of the trunk soundproofing element 8 and therefore of the fixing housing 70. In other words, the openings 12 of the under-seat carpet 10, the lights 80 of the trunk soundproofing element 8 and the fixing housings 70 of the carpet support 7 are aligned vertically with respect to each other, so that for an opening 12, a light 80 and a fixing housing 70 given in vertical alignment, a fixing member 9 can pass through them simultaneously in order to secure them to the carpet support 7.

[0078] Thus, when the carpet support 7 has a single fixing housing 70, then the under-seat carpet 10 has a single opening 12 located opposite the single light 80 of the trunk soundproofing element 8, so that the single fixing member 9 is simultaneously engaged in the fixing housing 70, through the light 80 and the opening 12.

[0079] In the case where the carpet support 7 has a plurality of fixing housings 70, then the under-seat carpet 10 has a plurality of openings 12, each opening 12 being located opposite one of the lights 80 of the trunk soundproofing element 8 and one of the fixing housings 70, so that each fixing member 9 is simultaneously engaged in one of the fixing housings 70 and through one of the lights 80 and one of the openings 12. It should be noted that, in the case where the carpet support 7 has a plurality of fixing housings 70, then the openings 12 are distributed longitudinally along the edge 11 of the under-seat carpet 10, preferably regularly distributed, a distance between two openings 12 being constant and equal to the constant D defined previously.In the case where the carpet support 7 has a plurality of fixing housings 70, it is also preferred that the openings 12 be aligned with each other, along the longitudinal axis x.

[0080] Figure 6 shows a cross-section of the trunk floor arrangement 3 of Figure 5. The straight section passes through the center of one of the fasteners 9, which passes through the panel 11 of the under-seat carpet 10, the end flap 83 of the trunk soundproofing element 8, and the mounting housing 70 of the carpet support 7. In this illustrated example, panel 11 overlaps the end flap 83. In other words, panel 11 covers the end flap 83, which itself covers the upper face 73 of the carpet support 7. Thus, the end flap 83 of the trunk soundproofing element 8 is in an intermediate position, or sandwiched, between the under-seat carpet 10 and the carpet support. 7. Of course, it can be provided that the terminal flap 83 covers the panel 11, which itself covers the upper face 73 of the carpet support 7. Thus, the panel 11 of the under-seat carpet 10 would be in an intermediate position, or sandwiched, between the terminal flap 83 and the carpet support 7.

[0081] This solution ensures a robust fixing of the under-seat mat 10 and the trunk soundproofing element 8, enabling it to withstand any stress exerted in any direction, while ensuring their correct position in the motor vehicle 1.

[0082] Fig. 7 shows an example of an alternative embodiment, in which the boot floor arrangement 3 includes a boot floor trim 15, intended to extend outward from the boot 2, into the passenger compartment of the motor vehicle 1. In the illustrated example, the boot floor arrangement 3 includes the carpet support 7 (not visible), the boot soundproofing element 8, the under-seat carpet 10 and the boot floor trim 15.

[0083] The trunk floor trim 15 separates the trunk 2 from the seating area of ​​the motor vehicle 1. The trunk floor trim 15 also ensures that items located in the trunk 2 are securely held, particularly in the event of sudden braking or a collision. When an object has become lodged between the seats and the trunk floor trim 15, the latter must be sufficiently robust to prevent movement of the seat behind which it is positioned and behind which the object has become lodged.

[0084] Fig. 8 shows a cross-section of the trunk floor arrangement 3 illustrated in Fig. 7, the straight section passing through the fixing member 9 being in the form of a fixing finger 150.

[0085] The trunk floor trim 15 has one or more fixing fingers 150, each configured to collaborate with the fixing slot(s) 70 of the carpet support 7. Each fixing finger 150 of the trunk floor trim 15 thus forms the fixing member 9. Indeed, in the presence of the trunk floor trim 15, the fixing member(s) 9 in the form of an added part, i.e. in the form of a pin or screw, possibly present, are removed to make room for the fixing finger 150 in the fixing slot 70.

[0086] The collaboration between the fixing member 9 in the form of a fixing finger 150 and the fixing housing 70 allows the various elements to be fixed to the carpet support 7. The fixing fingers 150 are manufactured by injection on the underside of the trunk floor trim 15, during its manufacture.

[0087] In all cases, the fastening between the fastening member 9 and the fastening housing 70 is temporary, detachable, and repositionable. When the trunk floor trim 15 acts as a fastening member 9, using the finger of As fixed at 150, the various elements are secured to the carpet support 7, and their correct positioning relative to the vehicle 1 is also ensured. Correct positioning means that the trunk soundproofing element 8, and, where present, the under-seat mat 10, cover the floor of the vehicle 1 without forming creases or leaving any part of the floor visible.

[0088] In the example illustrated in [Fig. 8], the panel 11 of the under-seat mat 10 covers the end flap 83, which itself covers the upper face 73 of the mat support 7, and the fastening finger 150 simultaneously passes through one of the slots 80 in the under-seat mat 10 and one of the openings 12 in the trunk soundproofing element 8, as well as one of the fastening slots 70. The panel 11 of the under-seat mat 10 is therefore located in an intermediate position between the mat support 7 and the trunk floor trim 15. More precisely, the panel 11 of the under-seat mat 10 is located in an intermediate position between the end flap 83 of the trunk soundproofing element 8 and the trunk floor trim 15. The panel 11 of the under-seat mat 10 and the end flap 83 of the element trunk soundproofing elements 8 are therefore located in an intermediate position between the carpet support 7 and the trunk floor trim 15.

[0089] Each fixing finger 150 of the trunk floor trim 15 passes through each opening 12 of the under-seat carpet 10 and the lights 80 of the soundproofing element 8 and collaborates with each fixing housing 70 of the carpet support 7.

[0090] Of course, it is possible to provide that the boot floor arrangement 3 is not equipped with the under-seat mat 10. Thus, the terminal flap 83 of the boot soundproofing element 8 is located in an intermediate position between the carpet support 7 and the boot floor trim 15, each fixing finger 150 of the boot floor trim 15 passing through one of the slots 80 of the boot soundproofing element 8 and collaborating with the dedicated fixing housing 70 of the carpet support 7.

[0091] Preferably, the trunk floor arrangement 3 includes three fixing slots 70 provided in the carpet support 7, three lights 80 provided in the trunk soundproofing element 8, three openings provided in the under-seat carpet 10, when present, and three fixing devices 9.

[0092] This invention provides a means of retaining the trunk soundproofing element 8 and the under-seat mat 10 when the user temporarily removes the trunk floor lining 15 from their motor vehicle 1 in order to obtain a larger cargo volume. Furthermore, the possibility of removing the trunk floor lining 15 ensures that the user does not have any protruding elements in the trunk 2, thus facilitating the placement and sliding of items to be transported into the trunk 2.

[0093] Replacing the boot floor trim 15, i.e. the fixing fingers 150, with a removable fixing element also makes it possible to avoid leaving any edge of material visible in order to ensure a satisfactory aesthetic result, while ensuring resistance to any stress exerted on the boot soundproofing element 8 and on the under-seat carpet 10. In other words, the presence of one or more fixing elements 9 therefore prevents the boot soundproofing element 8 and the under-seat carpet 10 from coming out of the stack made on the carpet support 7 and thus prevents any risk of visibility of an edge of material (most often white) which would degrade the aesthetic quality if it is visible in this area of ​​the boot 2 which is generally dark.

[0094] When replacing the trunk floor trim 15, he will remove the fasteners 9 from the fastener housings 70 and then replace the trunk floor trim 15, making the fastener fingers 150 work with the fastener housings 70.

[0095] This invention also allows the attachment of an additional element provided that openings made in this additional element correspond with the attachment housings 70 of the carpet support and collaborate with the attachment member 9.

[0096] The present invention therefore ensures correct indexing of the trunk soundproofing element 8 and the under-seat mat 10, adequate fixing resistant to any stress, and prevents any acoustic leakage.

[0097] In summary, the invention relates to a trunk floor arrangement 3 for a motor vehicle 1. The trunk floor arrangement 3 comprises a carpet support 7, a trunk soundproofing element 8 and at least one fastening member 9. The carpet support 7 includes at least one fastening housing 70. The trunk soundproofing element 8 includes an end flap 83 in which at least one light 80 is located opposite the fastening housing(s) 70 and the fastening member 9 is engaged through one of the lights 80 of the trunk soundproofing element 8 and one of the fastening housings 70.

[0098] Of course, the invention is not limited to the examples just described, and many modifications can be made to these examples without departing from the scope of the invention. In particular, the various features, forms, variants, and embodiments of the invention can be combined with one another in various ways, provided they are not incompatible or mutually exclusive. In particular, all the variants and embodiments described above are combinable.
