Description

The present invention relates to a vehicle floor laying structure, and more particularly to a vehicle floor laying structure in which a carpet is laid on the floor surface.

Generally, in a vehicle such as an automobile, a fiber floor carpet such as a tufted carpet or a needle punch carpet is adopted as a floor carpet laid on the floor surface in the vehicle. These are formed three-dimensionally, for example, by heating the carpet raw fabric, which is lined (laminated) with a thermoplastic resin on the back surface, and press-molding it so as to have a shape that conforms to the floor shape. On the other hand, resin floor carpets made only of resin have been adopted for products with a substantially flat shape such as floor carpets and floor mats (accessory mats, piece mats, option mats) formed by vacuum forming. There is no example of adoption of a floor carpet laid on the floor surface in a car and formed by injection molding so as to have a three-dimensional shape along the unevenness of the floor surface. For example, Patent Document 1 discloses a floor carpet made of resin. By laying these floor carpets on the floor surface, it is expected that the floor surface of the vehicle will be protected and the design and treading comfort will be improved.

By the way, the floor surface of the vehicle has irregularities depending on the physical structure of the vehicle. Therefore, when the floor carpet is laid on the floor surface, when the occupant of the vehicle steps on the floor carpet, the floor carpet follows the unevenness of the floor surface and is deformed, so-called bumping occurs. However, as a result, the treading comfort becomes uncomfortable, the safety and comfort are impaired, and the commercial value is significantly deteriorated.

Therefore, between the floor of the vehicle and the floor carpet, urethane foam molded from urethane with different thicknesses may be interposed, felt layers of different thicknesses may be interposed, or flat felt may be placed on the back surface of the floor carpet. It is conceivable to prevent the safety and comfort from being impaired as described above even if the floor surface is uneven by laminating.

By the way, it is preferable to provide the vehicle with functional parts such as a heel pad for preventing the wear of the skin of the floor surface and a hook for fixing the equipment mat. In that case, the manufacturing cost of the entire vehicle and the parts assembly There is a problem that the work man-hours for attachment and the management man-hours increase.

Further, as described above, when a resin molded body such as urethane foam is interposed between the floor surface of the vehicle and the floor carpet, the urethane foam having a thickness corresponding to the unevenness in each region where the unevenness exists. It is necessary to produce a resin molded product such as. Therefore, there is a problem that a dedicated facility for manufacturing a resin molded product such as urethane foam is required, quality control and a process are complicated, and one of the causes is an increase in cost. Further, a felt layer having a partially different thickness and / or a partially different texture may be interposed between the floor surface of the vehicle and the floor carpet, or a flat felt or chip urethane molded product may be provided on the back surface of the floor carpet. When laminating or foamed bead molded products, prepare a felt layer with a thickness corresponding to the unevenness of the floor surface for each area where the unevenness exists, or adjust the number of flat felts to be stacked. Must. Therefore, in this case as well, quality control and processes become complicated, and there is a concern that it will be one of the causes of increased cost.

The present invention has been made in view of the problems of the conventional technique as described above, and it is possible to reduce the manufacturing cost and man-hours, and to make cleaning and sterilization easier and more reliable. It is intended to provide a vehicle floor laying structure that can be carried out in.

In order to achieve the above object, the present invention

In particular, it is suitable for vehicles such as shared cars, taxis, and commercial vehicles in which passengers frequently change, because cleaning and sterilization can be performed more easily and more reliably. Further, as the functional parts of the present invention, since at least a part of the functional parts installed or extended on the floor surface is integrated with the carpet, the number of parts can be reduced, so that the manufacturing cost and the parts assembly can be reduced. The work man-hours and management man-hours for attachment are reduced, and the mold investment cost of the entire vehicle is reduced.

Further, the carpet has a height corresponding to unevenness on the surface facing the floor surface, and has a height adjusting member that expresses a required space at the height, and the height adjusting member is a functional component. Or, if the carpet forms part of a functional component and the height from the floor is achieved by the height adjusting member, the occupants of the vehicle will be able to lay the carpet on the uneven floor. When you step on the carpet with your feet, you will not feel uncomfortable and your safety and comfort will not be impaired. In this way, with a simple configuration in which a height adjusting member having a height corresponding to the unevenness is provided on the surface of the carpet facing the floor surface, safety and comfort are provided according to the unevenness existing on the floor surface. It will be avoided that the sex is impaired. In addition, the required space is created by the height adjusting member, so that the conventional resin molded body such as urethane foam and the felt layer are replaced with a structure containing a large amount of space, which can be expected to reduce the weight. A heavy wall is formed, and the effect of improving sound absorption and sound insulation can be expected. Further, even when the functional component integrated with the carpet has a predetermined height from the floor surface, it is not necessary to use a separate component to realize the height. In addition, the height adjustment member makes it a floor laying structure with a space inside, so it is possible to achieve weight reduction, impart heat insulation and sound absorption, and heat insulation due to the effect of the created space.

Further, if felt or other cushioning material is interposed between the floor surface and the carpet, or at least a part of the space inside the carpet, the sound absorbing property and cushioning property of the felt or other cushioning material may cause the inside of the vehicle. In terms of quietness and the comfort of stepping on the carpet, it is possible to achieve the same or better performance than before.

Further, if the resin material is applied to the upper surface or the lower surface of the felt, it is possible to provide the necessary portion with the necessary sound insulation.

In addition, if the number, plate thickness, or diameter of the height adjusting member is set according to the position of the vehicle, the required treading comfort can be adjusted at any time by adjusting the optimum value according to the vehicle requirement / part. For example, if the number, plate thickness, or diameter of the height adjusting member in the area corresponding to the riding position of the occupant of the vehicle is larger than in other areas, the treading comfort of the carpet is improved.

Further, when an engaging member that engages with a vehicle component installed in the vehicle is provided on the floor surface, the floor laying structure is one of the engaging members in a region facing the engaging member. If the hole for exposing the portion is opened and the opening edge of the hole has an eaves portion that covers a part of the engaging member, the appearance is not deteriorated or the foot is not caught. , A configuration is realized in which the vehicle parts are engaged with the engaging member.

According to the present invention, since the carpet is made of resin, cleaning and sterilization can be performed more easily and more reliably, and cleaning property, antifouling property and cleanliness can be improved. In addition, since at least a part of the functional parts installed or extended on the floor can be integrated into the carpet, the number of parts can be reduced, so that the manufacturing cost and the work for assembling the parts can be reduced. The man-hours and management man-hours can be reduced, and the mold investment cost of the entire vehicle can be reduced.

Further, the surface of the carpet facing the floor surface is provided with a height adjusting member having a height corresponding to the unevenness existing on the floor surface and expressing a required space at the height, and the height adjusting member can be provided. , A functional part, or a part of a functional part, and in the case where the carpet realizes the height from the floor surface by the height adjusting member, when the carpet is laid on the floor surface where unevenness exists. However, it is possible to realize a configuration that does not impair safety and comfort with a simple configuration. In addition, the required space is created by the height adjusting member, so that the conventional resin molded body such as urethane foam and the felt layer are replaced with a structure containing a large amount of space, which can be expected to reduce the weight. A heavy wall is formed, and the effect of improving sound absorption and sound insulation can be expected. Further, even when the functional component integrated with the carpet has a predetermined height from the floor surface, the height of the functional component can be realized without using a separate component. In addition, the height adjustment member makes it a floor laying structure with a space inside, so it is possible to achieve weight reduction, impart heat insulation and sound absorption, and heat insulation due to the effect of the created space. Can also be granted.

Further, in the case where felt or other cushioning material is interposed between the floor surface and the carpet, or at least a part of the space inside the carpet, the sound absorbing property and cushioning property of the felt or other cushioning material may be used. In terms of quietness inside the vehicle and the comfort of stepping on the carpet, it is possible to achieve performance equal to or better than before.

Further, in the case where the resin material is applied to the upper surface or the lower surface of the felt, it is possible to provide the necessary part with the necessary sound insulation.

In addition, if the number, thickness or diameter of the height adjusting member is set according to the position of the vehicle, it can be adjusted to the required treading comfort at any time by adjusting it to the optimum value according to the vehicle requirements and parts. .. For example, if the number, plate thickness, or diameter of the height adjusting member in the region corresponding to the riding position of the occupant of the vehicle is larger than in other regions, the treading comfort of the carpet can be improved.

Further, when an engaging member that engages with a vehicle component installed in the vehicle is provided on the floor surface, the floor laying structure is one of the engaging members in a region facing the engaging member.

In the vehicle shown in FIG. 1, it is a figure which shows the so-called foot pool area where a occupant of a vehicle steps on a carpet with a foot.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an example of a vehicle in which the floor laying structure of the present invention is adopted.

As shown in FIG. 1, in the vehicle 1 in which the floor laying structure of the present invention is adopted, the seat 4 is installed on the floor surface 2 in the vehicle, and the carpet 3 is laid. In the present embodiment, a configuration in which the seat 4 is a three-row seat having three rows and the second seat and the third seat of the three rows of seats 4 slide back and forth will be described as an example.

In the floor laying structure of the vehicle of the present invention, the carpet 3 laid on the floor surface 2 has a shape different from that of the conventional carpet. Hereinafter, the configuration of the carpet 3 at the feet of the driver's seat and the passenger seat among the three rows of seats 4 and the configuration of the carpet 3 at the feet of the second seat among the three rows of seats 4 will be described.

As shown in FIG. 2, a center console is installed between the feet of the driver's seat and the feet of the passenger's seat at the feet of the driver's seat and the passenger's seat among the seats 4 in the three rows of the vehicle 1 shown in FIG. In the case of a rear-wheel drive vehicle, a tunnel-shaped convex portion 11 for arranging the drive shaft protrudes inside the vehicle. In addition, the floor mat fixture 14 for fixing the floor mat placed on the carpet protrudes inside the car and extends from the floor surface 2, and the side sill 12 directly under the door is covered with resin. Side step 13 is installed. In addition, a VIN lid 15 for confirming the VIN (Vehicle Identification Number) engraved on the floor surface 2 or the like is provided at the foot of the driver's seat, and the driver steps on the accelerator pedal (not shown). A heel pad 16 is provided in a region that abuts on the heel. Further, the floor surface 2 has a convex portion 17 (see FIG. 3) in order to avoid interference with a component (not shown) installed under the floor surface 2.

3A and 3B are views showing a cross section of AA'in the floor laying structure shown in FIG. 2, where FIG. 3A is a diagram showing a conventional structure, and FIG. 3B is a diagram showing a structure of the present invention.

When the carpet 3 is placed on the area having the above configuration as shown in FIG. 1, conventionally, as shown in FIG. 3A, the fiber-based carpet 103 is placed on the floor surface 2. It will be placed. Here, since the carpet 103 is formed by cutting a flat material (fiber structure) in which a fiber layer, a lining resin layer, etc. are laminated to a fixed length and press-molding the carpet 103, the shape of the floor surface is formed. It is difficult to form a shape that perfectly matches the shape. For example, since it is a flat surface, if the convex portion 17 is present on the floor surface 2, when the occupant of the vehicle 1 steps on the carpet 103 with his / her foot, the carpet 103 follows the unevenness due to the convex portion 17 on the floor surface. , Deformation or so-called carpeting occurs, which makes the treading uncomfortable. Therefore, urethane foam 106 molded from urethane is interposed between the floor surface 2 and the carpet 103 at different thicknesses, or a floor spacer or a floor silencer made of separately molded felt or foam is raised. Materials (functional parts) are intervened. Further, a shock absorbing material called a tivia pad, which is formed by heat-foaming molded effervescent resin particles, is also interposed. Further, the floor mat fixture 14 and the VIN lid 15 are attached so as to be exposed from the holes provided in the carpet 103. Further, the side step 13 is provided with ribs integrated on the back surface thereof, whereby the height of the surface surface of the side step 13 from the side sill 12 is realized. Further, a harness protector 18 is provided on the side sill 12. The harness protector 18 is configured by forming a space in which the harness is built, for example, between the side sill 12 and the carpet 103 by ribs or the like.

On the other hand, in the floor laying structure of the present embodiment, as shown in FIG. 3B, the resin carpet 203 is placed on the floor surface 2. On the back surface of the carpet 203, a rib 208 serving as a height adjusting member is provided in a region not facing the tunnel-shaped convex portion 11. The height of the rib 208 is different between the area facing the convex portion 17 and the other area at the foot of the driver's seat and the foot of the passenger seat. The height of the rib 208 in the region facing the convex portion 17 is a value obtained by subtracting the protruding height from the floor surface 2 of the convex portion 17 from the height of the ribs in the other regions. Further, the carpet 203 is integrated with a floor mat fixture 214, a VIN lid 215, a side step 213, and a heel pad 16 (FIG. 2). This is realized by manufacturing the carpet 203 by injection molding of a resin. The side step 213 needs to be installed so that its surface has a predetermined height from the side sill 12. The carpet 203 is also provided with ribs 208 on its back surface in a region facing the side sill 12, and the height thereof corresponds to the height of the surface of the side step 213 from the side sill 12. As a result, the height of the side step 213 from the side sill 12 becomes a predetermined height. Further, also in the floor mat fixture 214 and the VIN lid 215, the required height is realized by the height of the rib 208 provided on the back surface of the carpet 203. Further, on the side sill 13, a space is created between the side sill 13 and the area serving as the side step 213 of the carpet 203 by the rib 208, and the harness protector 218 is configured by this space. Further, the felt 207 is interposed between the carpet 203 configured in this way and the floor surface 2.

As described above, in this embodiment, the rib 208 having a height corresponding to the unevenness existing on the floor surface 2 is provided on the surface of the carpet 203 laid on the floor surface 2 of the vehicle 1 facing the floor surface 2. The carpet 203 expresses the required space at the height of the rib 208. As a result, when the carpet 203 is laid on the floor surface 2 having unevenness, when the occupant of the vehicle steps on the carpet 203 with his / her feet, the feeling of stepping on the carpet 203 is not deteriorated and the safety and comfort are not impaired. .. At that time, the urethane foam 106 can be manufactured or the thickness varies from region to region with a simple configuration in which a rib 208 having a height corresponding to the unevenness is provided on the surface of the carpet 203 facing the floor surface. It is possible to avoid impairing safety and comfort depending on the unevenness existing on the floor surface 2 without laminating felt as described above. Further, since the carpet 203 is made of resin, cleaning and sterilization can be performed more easily and more reliably, and the cleanability and cleanliness are improved. Further, by expressing the required space by the rib 208, a double wall is formed, sound absorption and sound insulation are improved, and weight reduction can be achieved. At this time, since the carpet 203 is not provided with a hole for fixing the carpet 203 to the floor surface or ensuring ventilation, sound leakage can be prevented as much as possible and sound insulation is provided. It has become excellent. Further, the floor mat fixture 214 and VIN lid 215, which are functional parts installed on the floor surface 2, or the side steps 213, which are functional parts extending from the floor surface 2, are integrated into the carpet 203. Since the number of parts can be reduced, the manufacturing cost, the work man-hours for assembling the parts, and the management man-hours are reduced, and the mold investment cost of the entire vehicle is reduced.

Further, the height of the rib 208 of the carpet 203 realizes the height of the surface of the side step 213 from the side sill 12 and the height of the floor mat fixture 214 and the VIN lid 215 from the floor surface 2. There is no need to use separate parts to achieve the height of the side step 213, floor mat fixture 214 or VIN lid 215.

Further, since the felt 207 is interposed between the floor surface 2 and the carpet 203, the felt 207 acts as a silencer and a cushion due to the sound absorption and cushioning properties of the felt 207, and the quietness in the vehicle is improved. The treading comfort of the carpet 203 is improved. The felt 207 does not need to be interposed on the entire surface between the floor surface 2 and the carpet 203, and the above effect can be obtained if it is interposed on at least a part thereof, and further, the felt surface 2 and the floor surface 2 and the felt surface 2 and the carpet 203. It may be configured to be inserted in the space inside the carpet 203 instead of between the carpet 203 and the carpet 203. However, unlike the conventional urethane foam 106, the felt 207 can be interposed in a narrow area and can be easily interposed in the entire surface between the carpet 203 and the floor surface 2, so that it has sound absorption and quietness. Effective improvement of sexuality can be expected. In terms of quietness, not only the felt 207 but also the closed space formed between the region between the ribs 208 of the carpet 203 and the felt 207 is expected to have a sound absorbing effect due to Helmholtz resonance. Further, the closed space formed between the region between the ribs 208 of the carpet 203 and the felt 207 can also obtain the effects of weight reduction and heat insulation. Furthermore, unlike the conventional technology, it is not necessary to make different weights and different plate thicknesses in order to adjust the height and treading comfort for each part. be able to. For example, it is possible to use a simple felt with a constant basis weight and a constant flat plate thickness. Further, since the felt 207 is interposed between the floor surface 2 and the carpet 203, not only the abnormal noise due to the interference between the floor surface 2 and the carpet 203 can be prevented, but also the cooling duct and various electrical components can be used. By laying and arranging various parts to be laid on the vehicle such as harnesses that are arranged for this purpose, it is important that the non-woven fabric, protector, and cushioning material that are conventionally attached to these parts for the purpose of preventing abnormal noise can be eliminated. It can also play a role. Further, functional parts having functions such as positioning and holding of these parts may be integrated into the floor carpet. For example, the rib shape and the distance between the ribs can be designed so that the harness can be stored.

Further, the resin material may be applied by providing a resin packing on the entire upper surface or the lower surface of the felt 207, partially attaching a resin sheet, or providing a resin coating portion. In that case, the sound insulation can be improved.

FIG. 4 is a diagram showing the configuration of the foot of the second seat among the seats 4 in the three rows of the vehicle 1 shown in FIG. Since the one shown in FIG. 4 shows the configuration of the vehicle 1 having a general three-row seat, it does not have the configuration corresponding to the tunnel-shaped convex portion 11 shown in FIG.

As shown in FIG. 4, of the three rows of seats 4 of the vehicle 1 shown in FIG. 1, the foot of the second seat engages with the second seat, which is a vehicle component, in addition to the side step 13 shown in FIG. A slide rail 19 that serves as an engaging member for sliding the second seat back and forth of the vehicle 1 is arranged.

5A and 5B are views showing a cross section of AA'in the floor laying structure shown in FIG. 4, where FIG. 5A is a diagram showing a conventional structure, and FIG. 5B is a diagram showing a structure of the present invention.

When the carpet 3 is placed on the area having the above configuration as shown in FIG. 1, conventionally, as shown in FIG. 5A, the fiber-based carpet 103 is placed on the floor surface 2. It will be placed. Here, since the carpet 103 is formed by cutting a flat material (fiber structure) in which a fiber layer, a backing resin layer, etc. are laminated to a fixed length and press-molding the carpet 103, the shape of the floor surface is formed. It is difficult to form a shape that perfectly matches the shape. For example, since it is a flat surface, if the floor surface 2 has irregularities, the carpet 103 will be formed when the occupant of the vehicle 1 steps on the carpet 103, as in the case of FIG. 3A. It follows the unevenness of the floor surface and deforms, so-called bumping occurs, which makes the treading comfort worse. Further, since the slide rail 19 has a certain height, when the surface of the carpet 103 is made flat, the height of the carpet 103 in the area where the slide rail 19 is not arranged from the floor surface 2 is the height of the slide rail 19. It should be according to the rail. Therefore, urethane foam 106 formed by molding urethane is interposed between the floor surface 2 and the carpet 103 with different thicknesses. Further, on the slide rail 19, a resin slide rail cover 118 having a hole 119 for inserting a connecting portion provided at the lower part of the second seat is attached, and caps (caps () are attached to the front and rear ends thereof, respectively. (Not shown) is fitted.

On the other hand, in the floor laying structure of the present embodiment, as shown in FIG. 5B, the resin carpet 203 is placed on the floor surface 2. On the back surface of the carpet 203, a rib 208 serving as a height adjusting member is provided in the same manner as that shown in FIG. 3 (b). The height of the rib 208 corresponds to the height of the slide rail 19. As a result, the surface of the carpet 203 is flattened. Further, the carpet 203 is also extended on the slide rail 19, and has a form in which the slide rail cover 118 shown in FIG. 5A is integrated. In the area of the carpet 203 facing the slide rail 19, a hole 221 provided at the lower part of the second seat for entering the connecting portion is opened, and at the opening edge of the hole 221, one of the slide rails 19 is opened. An eaves portion 222 that covers the portion is provided. A felt 207 is interposed between the carpet 203 and the floor surface 2 thus configured as in the case shown in FIG. 3 (b).

As described above, in the present embodiment, the surface of the carpet 203 laid on the floor surface 2 of the vehicle 1 facing the floor surface 2 is provided with a height corresponding to the unevenness existing on the floor surface 2, and the height corresponds to the unevenness. By providing the rib 208 for expressing the required space, when the carpet 203 is laid on the floor surface 2 having irregularities similar to that shown in FIG. 3 (b), the occupant of the vehicle can use the carpet. When the 203 is stepped on with a foot, the treading comfort is not deteriorated and the safety and comfort are not impaired. At that time, the urethane foam 106 can be manufactured or the thickness varies from region to region with a simple configuration in which a rib 208 having a height corresponding to the unevenness is provided on the surface of the carpet 203 facing the floor surface. It is possible to avoid impairing safety and comfort depending on the unevenness existing on the floor surface 2 without laminating felt as described above. Further, since the height of the rib 208 corresponds to the height of the slide rail 19 arranged on the floor surface 2, the surface of the carpet 203 can be flattened. Further, the carpet 203 has a hole 221 that exposes the slide rail 19 in a region facing the slide rail 19, and an eaves 222 that covers a part of the slide rail 19 at the opening edge of the hole 221. By integrating the conventional slide rail cover 118 that covers the slide rail 19 with the carpet 203, the second sheet can be joined without making the appearance worse or catching the foot. It is possible to realize a configuration in which the portion is engaged with the slide rail 19. Furthermore, the slide rail cover itself can be eliminated. Depending on the vehicle, there are many slide rails with eight or more per vehicle. Therefore, by eliminating the slide rail cover, the number of parts and the assembly process can be reduced.

In this embodiment, the floor mat fixture 214, the VIN lid 215, the side step 213, or the slide rail cover 118 have been described as examples of the functional parts to which the carpet 203 is integrated, but the integrated functions have been described. The parts are not limited to this, and at least a part of the functional parts of the vehicle may be integrated. For example, functional parts such as a tivia pad having a shock absorbing function and a footrest arranged for mounting the feet of an occupant may be integrated into the carpet 203. Further, functional parts such as a storage pocket, a handle that serves as a grip for carrying, and a grip may be integrated into the carpet 203.

Hereinafter, the rib 208 provided on the carpet 203 of the present embodiment will be described in detail.

As described above, the carpet 203 of the present embodiment has a height corresponding to the unevenness existing on the floor surface 2 of the vehicle 1, so that when the occupant of the vehicle steps on the carpet 203 with his / her foot, the carpet 203 has a floor surface. It follows the unevenness of the floor and prevents it from being deformed or causing so-called bumping, which makes it uncomfortable to step on and impairs safety and comfort. Therefore, it is preferable that the rib 208 provided on the back surface of the carpet 203 is not easily deformed when the occupant of the vehicle steps on the carpet 203 with his / her foot.

FIG. 6 is a diagram showing a so-called foot pool area in which the occupant of the vehicle steps on the carpet 203 with his / her foot in the vehicle 1 shown in FIG. In the configuration shown in FIG. 6, the tunnel-shaped convex portion 11 is not for arranging the drive shaft, but for installing the center console, and therefore, between the driver's seat and the passenger's seat. It exists only in the rear wheels (not shown) and does not extend to the area between the rear wheels (not shown).

As shown in FIG. 6, in the vehicle 1 shown in FIG. 1, in the area other than the shielding area 31 where the seat 4 is installed, the luggage compartment area 32, and the tunnel-shaped convex portion 11, the occupant of the vehicle is carpet 203. It is a so-called foot pool area 33 where the foot is stepped on. This foot pool area is the area corresponding to the riding position of the occupant of the vehicle 1 in the present invention. In addition to the tunnel-shaped convex portion 11 shown in FIG. 6, the convex portion is formed on a cross member formed so as to cross in the width direction in the middle of the front-rear direction of the floor surface 2 and on both left and right ends. There are convex portions such as rocker panels, and the carpet is formed with convex portions that cover these convex portions.

Since the foot pool region 33 is a region where the occupant of the vehicle steps on the carpet 203 with his / her foot, it is preferable to increase the number of ribs 208 and the plate thickness as compared with other regions. Thereby, the treading comfort and strength of the carpet 203 can be improved. In this embodiment, the rib 208 has been described as an example of the height adjusting member, but the rib 208 may be formed in a grid pattern or a line shape. Further, the height adjusting member is not limited to the rib 208, and may be a convex or cylindrical boss as long as it functions as a spacer as a functional component. Further, the rib 208 is not limited to the foot pool area 33, and if the number, plate thickness or diameter is set according to the position of the vehicle, it is always necessary by adjusting the rib 208 to the optimum value according to the vehicle requirement / part. You can adjust the treading comfort and reduce the weight.

Further, as described above, the carpet 203 is manufactured by injection molding of a resin. Therefore, in addition to the effect of improving cleanliness and cleanliness, unlike textile carpets, patterns and grooves are formed in a line extending in the front-rear direction of the vehicle, and depending on the color of the seat or door panel, etc. It is also possible to apply metal-like or wood-grain-like printing. As a result, it will be possible to provide various variations of carpets according to the vehicle type, its color, and grade. For example, a black carpet can be standard equipment, and a metal-like or wood-grain carpet can be selected as an option. Further, various known techniques conventionally used for door trims formed by resin molding can be easily diverted to this floor portion. For example, it is conceivable to partially apply a skin at the same time as molding the fabric (HPM) at the same time as molding, or to change the color or material by using a two-color molding technique. In addition, when the skin is partially applied, it is conceivable to use wood grain technique, illumination technique, or plating technique.

Further, the carpet 203 is not limited to the one placed on the floor surface 2 as a single structure. For example, the carpet placed in the driver's seat and passenger's seat areas, the carpet placed in the second seat area, and the carpet placed in the third seat area may be separated. As a result, it becomes easy for the user to replace the carpet, and it is possible to use a carpet having a different design depending on the season or the like. In that case, it is conceivable that each carpet is provided with a boss and a hole through which the boss enters, and these are engaged with each other to prevent the carpets placed on the floor surface 2 from slipping from each other. Since it is manufactured by injection molding, it is possible to easily manufacture an engaging portion such as a boss or a hole.

Further, if a part of the carpet 203 is made into a bellows shape or a part of the carpet 203 is made of an elastic material so that the part of the carpet 203 can be expanded and contracted, the size and shape will vary due to injection molding. Can be absorbed.
