Description

The present invention relates to an improved device for supporting a trunk panel of a motor vehicle. Such a trunk board is also called a trunk floor. In the state of the art, there is already known a first type of support device for a trunk panel, capable of carrying this trunk panel in different possible positions, each position being defined at a different height in a vertical direction. . For this purpose, this support device comprises a plurality of support portions, each disposed at a respective level in the vertical direction, and each being adapted to support the trunk panel. Thus, each support portion defines a possible position for the trunk board. Such a support device allows the extraction of the trunk panel and / or its repositioning to a different level. It is thus possible in particular to compartmentalize the trunk space, for example to optimize the provision of luggage in this trunk. Furthermore, since the trunk panel is likely to be extracted entirely from the trunk, such a device also has the advantage of allowing a complete release of the trunk space, to facilitate the cleaning of the trunk panel, and allow the use of a reversible boot panel.

Such a reversible boot panel comprises, for example, a first face covered with a carpet in the same manner as the rest of the trunk dressing, and another face covered with a coating less subject to abrasion or the dirt. Also known in the state of the art, a second type of support device of a trunk panel for sliding of the trunk panel to the outside of the trunk in a longitudinal direction for the purpose of help with loading. Such a support device makes it possible to put a load on the trunk board when it is slid out of the trunk, the board then being slid towards the inside of the trunk with the load.

For security reasons, such a support device comprises means forming a stop, limiting the sliding of the panel towards the outside of the box, in order to prevent its complete extraction. Indeed, in the absence of such a stop, it would be dangerous to manipulate the panel when carrying a heavy load. Thus, these two types of support devices are incompatible, insofar as a device of the second type prohibits the extraction of the trunk panel, and therefore does not allow to have the advantages of a device of the first type, in particular to allow arrange the panel at various heights or use a reversible panel. The present invention is intended to overcome this disadvantage, providing a support device of a trunk panel having both the advantages of the support devices of the two types described above, while remaining effective, secure and economical. For this purpose, the subject of the invention is in particular a device for supporting a trunk panel of a motor vehicle, characterized in that: the support device comprises at least one front pillar, extending at least in a first direction, said vertical, and having at least two front support portions, each disposed at a respective level in the vertical direction, each of the front support portions being adapted to support a front portion of the trunk board, - the support device comprises at least one rear upright, extending at least in the vertical direction, and carrying at least two rear support parts, each arranged facing a respective front support part in a second, so-called longitudinal direction perpendicular to the direction vertical, each of the rear support portions being adapted to support a rear portion of the trunk panel, the rear post comprises guiding means translating the trunk panel in the longitudinal direction, carrying at least one of the rear support portions, for translational guidance of the panel between a forward position, wherein the trunk panel is at least partly supported by the front support which is arranged facing this rear support portion, and a rear position, said guide means comprising a rear stop intended to be in contact with a first complementary stop formed on the trunk board, when the trunk board is in its rear position, the front and rear uprights are arranged at a distance from each other in the longitudinal direction, so as to delimit between them an access passage allowing the access of the boot panel to each of the parts front and rear support.

The support device being formed by two uprights arranged at a distance from each other in the longitudinal direction, it is possible to manipulate the panel through the access passage delimited between these two uprights, in particular to position this panel on different heights, each corresponding to respective front and rear support portions.

Said access passage being formed between the front and rear uprights, it is necessary to overcome the rear pillar to manipulate the trunk panel to change its height or to extract it from the device. Thus, the device according to the invention does not allow accidental extraction of the panel, especially when it carries a load. Moreover, at least one of the rear support portions being equipped with translation guiding means, the device according to the invention allows the sliding of the panel towards the outside of the trunk, in the same way as a device of the second type as described above. These guide means being provided with a limit stop, limiting the movement of the panel towards the outside of the box, they do not allow the extraction of the panel through these guide means. The device according to the invention therefore remains just as secure as a device of the second type described above.

The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures in which: FIG. 1 is a perspective view of a set of a trunk panel of a motor vehicle and a support device for this panel, according to an exemplary embodiment of the invention; - Figure 2 is a top view of the trunk panel of the assembly of Figure 1; FIG. 3 is a perspective view of the support device of the assembly of FIG. 1; - Figure 4 is a longitudinal sectional view of the device of Figure 3; - Figure 5 is a partial perspective view of the assembly of Figure 1, wherein the panel is disposed at a first height; - Figures 6 and 7 are similar to Figure 5, showing the assembly of Figure 1 wherein the panel is disposed at a second height, the panel being respectively shown in a forward and reverse sliding position; FIG. 8 is a view similar to FIG. 5 of the assembly of FIG. 1, in which the panel is represented at a third height; - Figure 9 is a partial perspective view of the assembly of Figure 1, wherein the panel is in an intermediate position of arrangement at the first height, or withdrawal from this first height. FIG. 1 shows an assembly 10 formed of a trunk panel 12 of a motor vehicle (also called a "false floor"), and a device 14 for supporting this panel 12.

In the following description, a first direction Z is defined corresponding to a vertical direction when the assembly 10 equips a motor vehicle resting on a horizontal surface. This first direction Z is therefore also called "vertical direction". A second direction X, perpendicular to the vertical direction Z, coinciding with a longitudinal direction of the motor vehicle is also defined when the assembly 10 equips this motor vehicle. This second direction X is therefore also called "longitudinal direction". Finally, a third direction Y is defined, perpendicular to the vertical direction Z and to the longitudinal direction X, coinciding with a transverse direction of the motor vehicle when the assembly equips the motor vehicle. This third direction X is therefore also called "transverse direction".

Furthermore, in the present description, the terms "before" and "back" correspond to the usual definitions in a motor vehicle. In particular, the trunk of the motor vehicle is arranged at the rear of this motor vehicle. As shown in particular in Figure 1, the support device 14 comprises two lateral members 16, each being intended to be secured to a trunk side trim of the motor vehicle. More particularly, each lateral member 16 is advantageously formed by a trunk side trim. Thus, in the description which follows, each lateral member 16 will be called "side trim 16". The two side seals 16 are substantially similar, and symmetrically disposed relative to each other, so that only one of them will be described in detail. In particular, unless otherwise specified, each feature of one of these side trims 16 is found on the other of these side trims 16. The trunk panel 12 is intended to extend into the transverse direction Y between the lateral linings 16. The boot panel 12 is shown in more detail in FIG. 2. This boot panel 12 has, in the longitudinal direction X, a front part 18 and a rear part 20, such that the front portion 18 has a dimension, in the transverse direction Y, greater than the dimension of the rear portion 20 in the same transverse direction Y. The panel 12 therefore comprises at least one lateral shoulder 22 between the front portions 18 and rear 20. More particularly, the panel 12 has two lateral shoulders 22, arranged on either side of this panel 12 in the transverse direction Y, between the front parts 18 and rear 20 in the said X. Each shoulder 22 forms a first longitudinal stop of the panel 12, whose function will be described in more detail later. The front portion 18 has a generally rectangular shape delimited by side edges 18A and a front edge 18B. The rear portion also has a generally rectangular shape delimited by side edges 20A and a rear edge 20B.

Optionally, each lateral edge 18A, 20A is provided with a ruler 24 with a U-shaped section whose branches rest on either side of the panel 12 in the vertical direction Z. It will be noted that the panel 12 is for example made of composite material, sandwich type with cardboard spacer. Such a panel is relatively light, which facilitates handling and handling, and robust, so that it can withstand heavy loads, for example of the order of 100 kg.

The support device 14, which is formed by all of the two trunk side trims 16, will now be described with reference to FIGS. 3 and 4. In particular, as mentioned above, only one of the side trims 16 will be described below. the other is similar.

As shown in particular in Figure 3, the support device 14 extends in the longitudinal direction X between a rear end 14A and a front end 14B, and extends in the vertical direction Z between a lower end 17A and a upper end 17B. Each side trim 16 has a front upright 26 extending in particular in the vertical direction Z, delimited by the lower ends 17A and upper 17B. This front post 26 comprises at least two, for example three front support parts 28, each arranged at a respective level in the vertical direction Z. In other words, the front support parts 28 are aligned in the vertical direction Z, at different heights.

More particularly, in the example described, it defines an upper front support portion 28A, a lower front support portion 28C, and an intermediate front support portion 28B disposed between the lower front support portions 28C and greater 28A in the vertical direction Z. Each of the front support portions 28 is adapted to support the front portion 18 of the trunk panel 12. For example, each front support portion 28 is formed by a flat surface defined in a plane parallel to the directions longitudinal X and transverse Y, and extending mainly in the longitudinal direction X. The front upright 26 further comprises, for each front support portion 28, a stop before 30 intended to come into contact with a second longitudinal stop 31 complementary arranged on the trunk panel 12, to prevent movement of this trunk panel 12, in the longitudinal direction X, past this front stop 30, when this panel 12 rests on said corresponding front support portion 28. The second stop 31 is for example carried by a shoulder formed by a lateral notch formed at the junction of the front edge 18B and the side edge 18A of the panel 12. Alternatively, the second stop 31 is carried by the front edge 18B of the panel 12 According to another variant, the second stop 31 is carried by a plastic part, having damping and catch-up functions. In the following, the front stop associated with the upper front support portion 28A will be called the upper front stop 30A, the front stop associated with the intermediate front support portion 28B will be called the intermediate front stop 30B, and the front stop associated with the Lower front support portion 28C will be referred to as lower front stop 30C. Advantageously, each front support portion 28 is formed by a notch formed in the front post 26, so that the front post 26 provided with these notches form a rack. Each notch is delimited in the vertical direction by a horizontal flat wall forming the front support portion 28, and another wall facing. More particularly, the other wall of the notch forming the upper front support portion 28A forms an upper rim substantially parallel to this upper front support wall 28A. Furthermore, the other wall of the notch forming the intermediate support portion 28B or lower 28C forms a wall inclined facing this intermediate front support wall 28B or lower 28C. Each front stop 30 is formed in the bottom of the corresponding notch, in a junction zone between the horizontal wall 28 and the other corresponding facing wall. Thus, each inclined wall guides the panel 12 to the corresponding front stop 30 when it is inserted into the slot. Advantageously, this junction zone comprises a rounded hollow, facilitating the insertion of the panel 12. Each side lining 16 also comprises a rear upright 34, extending in particular in the vertical direction Z, and carrying at least two support parts. rear 36, for example three, each arranged facing a respective front support portion 28 in the longitudinal direction. More particularly, the rear post 34 has an upper rear support portion 36A, a lower rear support portion 36C, and an intermediate rear support portion 36B disposed between the lower rear support portions 36C and upper 36A in the vertical direction Z. In the longitudinal direction X, the lower rear support portion 36C is disposed substantially opposite the lower front support portion 28C, the intermediate rear support portion 36B is disposed substantially opposite the intermediate front support portion 28B, and the upper rear support portion 36A is disposed substantially facing the upper front support portion 28A. Each assembly formed by a rear support portion 36 and a corresponding front support portion 28 is referred to as a receiving stage of the panel 12. Thus, the support device 14 has an upper stage, formed by the upper front support portions 28A. and rear 36A, an intermediate stage, formed by the intermediate front support portions 28B and rear 36B, and a lower stage, formed by the lower front support portions 28C and rear 36C. Thus, when the front portion 18 of the panel 12 rests on one of the front support portions 28, the rear portion 20 of the panel 12 then rests on the rear support portion 36 of the same floor. According to the embodiment described, the rear upright 34 has a first lateral portion 38, extending in particular in the longitudinal direction X between a rear edge 38A and a front edge 38B, the front edge 38B being arranged opposite the upright 26 This first lateral portion 38 has, in the transverse direction Y, a dimension substantially equal to, or slightly smaller than, the dimension of the shoulder 22 of the panel 12 in the same direction. The rear upright 36 also comprises a second lateral part 40, integral with the first lateral part 38, projecting in the transverse direction Y from this first lateral part 38, in the direction of the other lateral gasket 16.

The upper rear support portion 36A is carried by this second lateral portion 40. Furthermore, the rear upright 36 has an upper rear stop 42A, carried by this second lateral portion 40. This upper rear stop 42A is intended to be in contact with a third abutment 43 of the trunk panel 12, when this panel 12 rests on the upper front support portions 28A and rear 36A. The third stop 43 is for example carried by the rear edge 20B of the boot panel 12. The upper rear stop 42A is advantageously arranged, in the longitudinal direction X, at a distance from the corresponding upper front stop 30A, which is substantially equal, or slightly greater, at the distance between the second 31 and third 43 stops of the boot panel 12. For example, the upper rear stop 42A is carried by a shoulder delimiting rearwardly the rear support portion 36A. Thus, when the trunk panel 12 rests on the upper front support portions 28A and rear 36A, it is immobilized in translation in the longitudinal direction X by the upper front stops 30A and rear 42A. The boot panel 12 is shown supported on this upper stage in FIG. 8. In accordance with the embodiment described, the rear upright 34 also comprises means 44 for guiding the trunk panel 12 in the longitudinal direction X in translation. guide means 44 carrying the intermediate rear support portion 36B.

These guide means 44 are intended to guide the panel 12 in translation between a forward position (shown in FIG. 6), in which this panel 12 is at least partly supported by the intermediate front support portion 28B, and a rear position (shown in Figure 7), wherein the panel 12 extends partly beyond the rear end 14A of the device 14, rearwardly in the longitudinal direction X. The guide means 44 comprise a rear stopper intermediate 42B intended to be in contact with the first stop 22 of the trunk panel 12 when the panel 12 is in its rear position. More particularly, the intermediate backstop 42B defines the rear position.

Thus, the trunk panel 12 can not be extracted from the support device 14 when it is slid in the longitudinal direction X. For example, the translational guiding means 44 comprise a first slideway 46 intended to cooperate with the edge 18A of the front portion 18 of the panel 12, this first slide 46 extending in the longitudinal direction X between the rear stop 42B and a leading end 46A arranged opposite the intermediate front support portion 28B. The translation guiding means 44 also comprise a second slide 48, offset in the transverse direction Y with respect to the first slideway 46, parallel to this first slide 46, and intended to cooperate with the lateral edge 20A of the rear portion 20. Advantageously, the first slideway 46 is carried by the first lateral portion 38 of the rear upright 34, and the second slideway 48 is carried by the second lateral portion 40 of the rear upright 34. The emergent end 46A of the first slideway 46 is then flush with the front edge 38B of the first lateral portion 38 of the rear upright 34. Each slideway 46, 48 advantageously comprises rolling elements 50, for example rollers, intended to roll on the panel 12 near the lateral edge 18A, 20A. corresponding. More particularly, these rollers 50 are intended to roll on the strips 24 fitted to the side edges 18A, 20A of the panel 12. Thus, the strips 24, for example metallic, take up the contact forces of the rollers 50, so that the panel 12 is not damaged by these rollers 50. It will be noted that the intermediate rear support portion 36B is carried by one of the rollers 50 of the second slide 48. In other words, the rear portion 20 of the panel 12 rests on this roller 50 when its front portion 18 rests on the intermediate front support portion 28B.

Preferably, at least one of the slides 46, 48 comprises resilient means 51 intended to urge the trunk panel 12 in the transverse direction Y towards the other lateral lining 16. These elastic means 51 comprise, for example, a lateral rolling element. mounted on an elastic member.

In the embodiment described, the elastic means 51 equip only one of the lateral linings 16. The other lateral lining 16 however comprises a lateral rolling element, so that the panel 12 is clamped laterally by the lateral rolling elements. of each side seal 16. It is clear that the guide means 44 allow the partial extraction of the trunk panel 12, in a secure manner since the translational movement of the panel 12 is limited by the rear stop 42B. According to the embodiment described, the support device 14 comprises a support member 52, generally formed by a bottom of the trunk of the motor vehicle. This support member 52 is integral with the rear pillar 38, and generally also integral with the front pillar 26. Advantageously, the boot bottom 52 has a flange 53, forming a loading threshold. This rim 53 is adapted to support the panel 12 when it is arranged at the intermediate stage. This rim 53 is optionally provided with rolling elements facilitating the translational movement of the panel 12 between its front and rear positions.

The support member 52 further has a flat surface 54, extending between the two side seals 16 in the transverse direction Y, for supporting the trunk board 12 when it rests on the lower front support portion 28C. In other words, this surface 54 carries the lower rear support portion 36C. The panel 12 disposed at this lower stage is shown in FIG.

It should be noted that the support device 14 comprises a lower rear stop 42C intended to be in contact with the third stop 43 of the trunk panel 12, when this panel 12 rests on said lower rear support portion 36C. Advantageously, the lower rear stop 42C is arranged, in the longitudinal direction X, at a distance from the lower front stop 30C, which is substantially equal to, or slightly less than, the distance between the second 31 and third 43 stops of the trunk panel. 12. Thus, the lower stops before 30C and 42C rear prohibit the translation of the panel 12 in the longitudinal direction X when the panel 12 is arranged in the lower floor. For example, the lower back stop 42C is carried by the rim 53 of the trunk floor 52.

The uprights 26 and rear 34 are arranged at a distance from each other in the longitudinal direction X, so as to delimit between them an access passage 56, allowing access to the trunk panel 12 to each of the parts front support 28 and rear 36.

In particular, the access passage 56 allows the insertion of the front portion 18 of the panel 12 to each of the front support portions 28. The arrangement of the trunk panel 12 on the different stages of the support device 14 is 5, the trunk panel 12 is arranged on the lower floor: the front lateral edge 18A rests on the lower front support portion 28C, and the rear portion 20 rests on the lower rear support 36C. To access this position, the front portion 18 of the panel 12 is inserted through the access passage 56, bypassing the rear pillar 34 from above in the vertical direction Z, until the second stop 31 comes. in contact with the lower front stop 30C. The panel 12 is then folded down, pivoting while maintaining the contact of the second stop 31 against the front stop 30C, until the rear portion 20 of the panel 12 comes to rest on the lower rear support portion 36C. In the same way, as shown in particular in FIG. 9, as shown in FIG. 6, the panel 12 is arranged at the intermediate stage by bringing the second stop 31 of this panel 12 into contact with the front stop. intermediate 30B, then folding the panel 12 until the rear portion 20 of the panel comes rest on a roller 50 of the second slide 48, forming the rear intermediate support portion 36B. The panel 12 is then in its forward position. Advantageously, a roller 50 of the first slide 46 supports one end of the front portion 18 of the panel 12 in this position. The panel 12 can then slide in the longitudinal direction, to its rear position shown in Figure 7, wherein the first stop 22 comes into contact with the rear stop 42B. Since the panel 12 is immobilized in the slides in the vertical direction Z, and in the longitudinal direction X by the rear stop 42B, the panel 12 can not be extracted from the support device 14 by sliding through the guide means 44. Support device 14 thus fulfills the usual safety criteria for a support device of the second type as defined above.

Finally, as shown in FIG. 8, the panel 12 is arranged on the upper stage by arranging the second stop 31 against the upper front stop 30A of the upper stage, and then folding the panel 12 until its rear portion 20 comes to rest on the upper rear support portion 36A.

Advantageously, the panel 12 is provided with a handle on its rear portion 20, allowing it to pivot upwards to move this panel 12 from one floor to another, each time by passing this panel 12 above It will be noted that the invention is not limited to the embodiment described, but could have various variants without departing from the scope of the claims.

In particular, several stages of the support device could be equipped with means for guiding the panel in translation. According to another variant, the panel could carry rolling elements intended to cooperate with the slideways of the translational guiding means, these slides then forming guide rails.

According to another variant, each lateral member 16 could be attached and fixed on a respective trunk side trim. As a variant, the intermediate front support portion 28B is at least partially slightly inclined downward in the vertical direction Z when considering a displacement in the longitudinal direction X from the front to the rear. Thus, when the panel 12 carries a heavy load, and that it flexes under the effect of this load, this inclined portion accommodates the panel 12 when moving from its rear position to its front position. This prevents the panel 12 is no longer facing the intermediate front support portion 28B due to its bending and abut against the amount before 26 below this intermediate front support portion 28B.

According to another variant, the panel 12 can be equipped, on its lower face, with rollers near the second stop 31, in order to facilitate the engagement on the front support portions 28. As a variant, the support device comprises locking means, for example integrated in at least one of the side seals 16 or in the panel 12, for blocking the panel 12 during its translation when it is arranged at the second floor. Such locking means comprise for example a retractable finger integrated in the side seal 16, intended to fit into complementary notches integrated with the strips 24 of the panel 12. According to another variant, the rear upright 34 could comprise stops , borne by its front edge 38B, intended to cooperate with the first stop 22 of the panel 12 when the panel 12 is arranged on the upper floor or the lower floor.
