Definitions

• the technical field relates to trim assemblies for passenger compartments of motor vehicles.
• the invention also relates to the kits making it possible to form several assemblies according to the invention, each being adapted to a particular vehicle and finally the invention relates to the vehicles equipped with such assemblies.
• a motor vehicle it is increasingly common for a motor vehicle to be offered to customers in several engine versions such as thermal energy, hybrid energy or even electric energy engines.
• Each version of such a vehicle generally has its own particularities which imply structural differences between each version, in particular under the bonnet and in the passenger compartment.
• the floor of the passenger compartment is very often different from one version to another to accommodate, for example, batteries for an electric or hybrid version or to allow the passage of an exhaust pipe of an engine thermal.
• the passenger compartment of the vehicle has a different volume specific to each version of the vehicle.
• This diversity of interiors means that car manufacturers must design and produce several different versions of most of the trim elements that are installed in the different interiors of the different versions of the vehicle.
• These trim elements which are available in several versions, generally include floor trim mats and side member trim.
• an object of the present invention is to overcome the problems set out above.
• an object of the present invention is to provide a trim assembly for trimming a vehicle passenger compartment which makes it possible to minimize the diversity of the trim elements used and which facilitates its assembly on the vehicle.
• the present invention relates to a trim assembly, for trimming the passenger compartment of a motor vehicle, comprising a passenger compartment carpet extending between a face side and a reverse side, the carpet comprising a lateral contour surface joining said faces, the assembly further comprising a soundproofing element, designed to occupy at least part of the space comprised between a vehicle cabin floor and the back face when the mat is installed in the vehicle, the assembly further comprising at least one trim element designed to at least partially conceal a side member of the vehicle, the assembly being characterized in that the mat is designed to be positioned in the passenger compartment of the vehicle with the contour surface positioned facing at least a part of the spar, the trim element being designed to mask, when it is installed on the spar, a part of the aspect face of the mat.
• the invention also relates to a trim kit for a motor vehicle comprising an assembly according to the invention and further comprising at least one additional soundproofing element, each being designed to be interchangeable with the soundproofing element of the together and to occupy a different volume.
• the invention also relates to a vehicle equipped with a packing assembly according to the invention.
• the invention relates to a method of trimming a motor vehicle according to the invention consisting in having a trim kit according to the invention and in selecting one of the soundproofing elements of the kit to form an assembly according to the invention adapted to the floor of the vehicle.
• the assembly according to the invention adapts to the passenger compartment of the vehicle, in particular to the floor to provide a single cabin carpet for all versions of the vehicle, the adaptation being made possible thanks to the element of soundproofing which can be chosen and adapted to at least partially fill the space between the passenger compartment floor and the back face of the mat.
• a kit according to the invention is thus particularly useful insofar as the soundproofing element or each additional soundproofing element of the kit can be adapted to a version specific to the vehicle. Thanks to the kit according to the invention, the lining of the passenger compartment of a vehicle having several versions is obtained with a single passenger compartment carpet combined with a suitable soundproofing element, chosen from the kit according to the invention, as indicated in the method of the invention.
• the diversity of the elements is further increased thanks to the interface between the trim element and the passenger compartment carpet: in fact, the passenger compartment carpet, when installed, does not go up behind the spar as is usually the case, since the lateral contour surface is positioned facing at least a part of the spar. This makes it possible to offer a single interface for all versions of the vehicle.
• the trim element which conceals part of the aspect face of the passenger compartment carpet, makes it possible to prevent the lateral contour surface from becoming visible to the user of the vehicle when it is in use.
• fixing the cabin carpet is superfluous and the assembly according to the invention is less complex to assemble.
• the trim element has a heel projecting from the trim element and designed to hide and rest on the facing face of the cabin carpet. Such a heel increases the covering of the carpet and thereby avoids the visual quality defects caused when the lateral contour surface of the carpet becomes visible to the user.
• the soundproofing element has at least one cavity accommodating a wedge designed to limit the compressibility of the soundproofing element.
• the soundproofing element according to the invention is made of porous and/or flexible material making it possible to absorb at least part of the sound waves which pass through it. Also, when the thickness of the soundproofing element required is significant, a shim makes it possible to limit the use of such a material, in particular its thickness. Indeed, without such a block, the soundproofing element would risk being too flexible, which could cause the mat to be held in place poorly under the effect of stress from the user.
• each soundproofing element has a different thickness.
• the thickness of each soundproofing element is adapted to a version of the vehicle.
• Figure 1 shows a perspective view of an assembly according to the invention mounted on a chassis of a vehicle according to the invention partially shown;
• Figure 2 shows a cross-sectional view along the axis AA of Figure 1 of a first version of the vehicle of Figure 1, showing the floor of the vehicle and the assembly according to the invention;
• Figure 3 shows a cross-sectional view along the axis AA of Figure 1 of a second version of the vehicle of Figure 1, showing the floor of the vehicle and the assembly according to the invention.
• a trim assembly 1, illustrated in the figures, is used to trim a passenger compartment 2 of a motor vehicle having several versions linked, for example, to various energy sources.
• the assembly 1 comprises a passenger compartment carpet 3 which extends between an appearance face 4 and a back face 5, illustrated in the figures.
• the aspect face 4 and the back face 5 are joined by a contour surface 6.
• the aspect face 4 is for example provided with carpeting and/or any other ornament provided.
• the aspect face 4 constitutes the face of the passenger compartment carpet 3 which is visible at least in part by the user of the vehicle installed in the passenger compartment 2.
• the assembly further comprises a soundproofing element 7 designed to occupy at least part, preferably all, of the space 8 between a floor 9 of the passenger compartment 2 and the reverse face 5 as illustrated in Figures 2 and 3.
• the soundproofing element 7 is made of porous or flexible material, for example a polymer foam, capable of absorbing at least part of a sound wave passing through it.
• the soundproofing element 7 is obviously adapted to the space 8 which is specific to the version of the vehicle. In other words, in each version of the vehicle, the soundproofing element 7 has a shape adapted to the space 8 and has a specific volume.
• Figure 2 illustrates a first version of assembly 1 adapted to a first version of passenger compartment 2
• Figure 3 illustrates a second version of assembly 1 adapted to a second version of the passenger compartment 2.
• the two passenger compartment versions 2 illustrated respectively in FIGS. 2 and 3 differ mainly in the shape of a spar 10a, 10b and in their floor 9a, 9b.
• the floor 9a of the first version, shown in Figure 2 differs from the floor 9b of the second version, shown in Figure 3, by their respective shapes and their positions relative to a reference mark RO of the spar 10a , 10b of the passenger compartment 2 of the vehicle.
• the cabin carpet 3 implemented for the two versions illustrated in FIGS. 2 and 3 is the same.
• the contour surface 6 of the belt 3 is positioned opposite at least a part of the spar 10a, 10b, more precisely opposite the reference mark RO.
• the soundproofing element 7a of the first version has a thickness less than the thickness of the element d soundproofing 7b of the second version, as shown in Figures 2 and 3.
• a cavity 11 is made in the soundproofing element 7b to accommodate a wedge 12, made of rigid material, designed to limit the compression of the soundproofing element 7b when stressed by a user.
• the assembly 1 according to the invention also comprises a packing element 13 of the spar 10 which is designed to mask, at least partially, the spar 10.
• the packing element 13 is designed and dimensioned to mask, when it is installed on the spar 10, a part of the aspect face 4 of the belt 3.
• the packing element 13 has at its end arranged opposite the aspect face 4 a heel 14 making it possible to increase the overlap of the carpet 3.
• the heel 14 makes it possible to increase the covering of the carpet 3 without increasing the thickness of the trim element 13 of the spar 10 in order to preserve the aesthetic appearance of the passenger compartment 2.
• the trim element 13 is held in position on the spar 10 by a lining support 15, illustrated in Figures 2 and 3, fixed in the spar 10.
• the shape of the lining support 14 is adapted to take into account possible variations in the shape of the spar 10, from one cabin version 2 to another version, so that a trim element 13 common to all the versions can be used. This is also made possible by the interface between the mat 3 and the trim element 13. Indeed, the mat 3 has no attachment to the spar 10 or to the trim element 13.
• a kit according to the invention comprises the carpet 13, the trim element 13 as well as, for example, the two soundproofing elements 7a, 7b.
• the method according to the invention consists in selecting from the kit the soundproofing element 7a, 7b adapted to the version of the vehicle.
• the assembly 1 according to the invention makes it possible to limit the diversity of the parts necessary to furnish two versions of a passenger compartment 2 since only the soundproofing element 7a, 7b must be developed and produced in as many versions as it There are versions of the vehicle according to the invention.
• the absence of fixing of the carpet 3 on the trim element 13 also makes it possible to simplify the implementation of the method according to the invention for trimming the vehicle according to the invention.
