SUMMARY OF THE INVENTION The present invention has been provided to solve the above-mentioned problems.
According to the first aspect of the present invention, the stationary slide rail of the seat is fixed on the floor panel, and the floor mat is formed of a raising material and a carpet, and the surface of the carpet is substantially the same height as the upper surface of the slide rail. Attach the fastener to the rear part of the carpet protruding from the raising material, fix the locking clip to the slide rail, and fit the locking tool into the locking clip with the carpet bent. It is characterized by being combined.
Therefore, there is no gap between the bent portion and the upper surface of the guide rail, and it is not necessary to employ a special molding or cover member. Since the bent portion formed in the carpet is sharply and linearly formed by the corners of the locking device, the carpet spreads to a point just before the slide rail, and a flat finish is obtained. Further, since the assembling is completed only by bending the carpet and fitting the locking tool to the locking clip, the assembling work is greatly simplified. Furthermore, since the locking member is a member having a simple cross-sectional shape, it can be manufactured at low cost by simple extrusion molding.

According to a second aspect of the present invention, in the first aspect, the locking member is formed as a long member having substantially the same length as the slide rail, and a corner portion of the locking member is a bent portion of the carpet. This feature is characterized in that the corners of the locking tool serve to form a linear bent portion. According to a third aspect of the present invention, in the second aspect, a concave groove for moderating the bending of the carpet is formed on the back surface of the carpet in the vicinity of the corner of the locking device over substantially the entire length of the locking device. The bent portion of the carpet can be reliably formed by the concave groove with a light bending force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 6 is a simplified plan view of a portion where the seat 12 is installed, and shows a state where floor mats are not spread. 13 is a seat, 14 is a seat back, 15 is a floor panel, 16
Is the center line of the car. A slide mechanism is provided to adjust the front-back position of the seat 12, and stationary slide rails 17, 17 which are part of the slide mechanism, are installed in parallel in the front-rear direction. This slide rail 17,
17 is fixed to the floor panel 15 via brackets, although not shown.

FIG. 1 is a sectional view taken along the line (1)-(1) in FIG. 6. Referring to other drawings, the stationary slide rail 17 made of a steel plate has a rectangular shape with a horizontally long cross section. An open groove 19 having inward flanges 18 and 18 is formed in the upper central portion thereof. The forward / backward rail 20 fixed to the seat 13 is formed by welding two steel plates together, and the lower portion thereof is bent left and right in the slide rail 17 to form a flat portion. A support piece 22 having a U-shaped cross section which is opened downward is welded to the flat portion, and a rolling roller 23 is supported by a shaft 24 therein.

The floor mat 25 is composed of a raising material 26 and a carpet 27 adhered thereto. The thickness and the vertical height of the slide rail 17 are selected. As shown in FIG. 6, three locking clips 30 are provided on each slide rail 17, and a steel plate or a spring steel plate is formed into a hat shape and welded to the lower side of the slide rail 17 as indicated by reference numeral 31. I have. Instead of this welding, other fixing means, for example, bonding or riveting may be adopted. Side plates 32, 32 having a vertical orientation are formed on the left and right of the locking clip 30, and the slide rails 17, 1
The insertion gaps 33, 33 are provided between the side surfaces 7 and 7. Flanges 34, 34 bent left and right are formed at the upper ends of the side plates 32, 32. The height of the flanges 34, 34 is substantially the same as that of the surface 28 and the upper surface 29 in consideration of the relationship with the thickness of the locking device described later. It is set to be height. The number of the locking clips 30 can be selected from a number other than three depending on the length of the slide rail 17 and the strength of fitting described later.

The locking members 35 are straight members having a long cross section similar to the numeral "7", and are formed by extrusion molding with a synthetic resin such as polypropylene. The end of the floor mat 25 is connected to the carpet 2 as shown in FIG.
7 is protruded from the raising material 26, and locking members 35, 35 are attached to the rear surface of the carpet 27. The cross section of the locking members 35, 35 is composed of long pieces 36, 36, short pieces 37, 37 bent at a right angle therefrom, and bent pieces 38, 38 bent at a substantially right angle from the short pieces. Is fixed to the back surface of the protruding portion of the carpet 27. In this fixing method, the staples 39 and 39 are employed, but an adhesive may be used instead.

The detailed shape of the bent pieces 38, 38 will be described with reference to FIG. 3. The bent pieces 38, 38 have a "-" cross section having a guide slope 40 and a clamp slope 41. The outer portion where the long piece 36 is bent from the long piece 36 to the short piece 37 is a corner 42, and a groove is provided near the corner 42, that is, as shown in FIG. 4
3 are formed. The concave groove 43 is provided over the entire length of the locking tool 35. The surface of the short piece 37 functions as a flat “receiving surface” in the assembled state of FIG. 1 as described later.

To explain the constituent materials of the floor mat 25, the raising material 26 is a sheet material made of urethane and having a thickness of about 20 mm. Here, a recycled product in which urethane chips are integrated with a binder is used. The carpet 27 is made of a nonwoven fabric, and a backing layer 44 is formed by impregnating one side of the carpet 27 with a polyurethane resin, and the groove 43 is also molded at the time of molding. The thickness of the carpet 27 is about 5 mm. The carpet 27 is integrated with the raising material 26 with an adhesive.

Next, a procedure for connecting the carpet 27 to the slide rail 17 after the floor mats 25 are laid down will be described. When the tip of the carpet 27 in the state as shown in FIGS. 2 and 3 is bent downward, the corner 4
The carpet 27 is bent along 2 to form a linear bent portion 45. Then, when the overlapping portion of the end of the long piece 36 and the end of the carpet 27 is inserted into the insertion gap 33, the guide slope 40 is elastically pushed and spread out while bending the guide slope 40 against the end of the flange 34 from the middle thereof. By pushing further into the insertion gap 33,
This time, the end of the flange 34 reaches the clamp slope 41, and the flange 34 is fitted into the clamp slope 41 as shown in FIG. Complete.

In FIGS. 2 and 3, the gap between the short piece 37 and the end face of the raising material 26 is set such that there is almost no gap between the short piece 37 and the raising material 26 when bent as shown in FIG. Have been.

In the above embodiment, the locking tool 35 is a so-called female type in which the locking tool 35 has a "7" shape and the locking clip 30 is inserted therein. In the embodiment of FIG. 5, the male and female are reversed. This is the case. That is, the locking member 35 having an L-shaped cross section is bonded to the back surface of the carpet 27 with the adhesive 46, and the insertion gap 33
It is pushed in as shown in the figure. Here, the corners of the locking device 35 and the bent portions 45 formed on the carpet by the same are the same as in the previous embodiment. In this case, the side plate 3 of the locking clip is used to prevent it from coming off.
2 and the locking member 35 are provided with an uneven portion 47 as shown. In order to prevent dust and the like from entering the slide rail 17 from the open groove 19, a dustproof rubber 48 shown by a two-dot chain line in FIG. 1 is employed. This dustproof rubber 4
8 is formed elongated along the slide rail,
It is attached by a method such as bonding to the upper surface 29 of the slide rail.

In order to specify the present invention, the expression "fitting" is used in the claims, which is different from the case where the locking device 35 is of a female type as shown in FIG.
As shown in FIG. 5, when the locking tool 35 is of a male type,
It is used in a generic sense.

Although not described in the claims, the following structure which can be specified from the embodiment has a function and effect unique to itself. That is, the cross-sectional shape of the locking member 35 is a so-called “7” shape, and the bent piece 38 is provided with the guide inclined surface 40 and the clamp inclined surface 41. The tool 35 is firmly connected. And since it is a "7" -shaped cross section, the bending rigidity of the locking tool 35 is high, and therefore, it is advantageous to form the linear bent portion 45. Further, the groove 43 can be easily formed by forming the groove 43 in the backing layer 44 impregnated with the synthetic resin at the time of molding.

[0017]

Since the present invention has the above-described configuration and operation, it has the following effects. That is, a modest bent portion can be formed by the locking tool, and no gap is formed between the bent portion and the upper surface of the guide rail, so that a special molding or cover member is not required. Since the bent portion formed in the carpet is formed sharply and linearly as described above, the carpet spreads to a point near the slide rail, and a flat finish is obtained. In addition, since a part of the locking device functions as a so-called “receiving surface”, the carpet is made of “raising surface”
Thus, it is supported from below without interruption, and the above-described flatness can be realized more reliably. Further, since the assembling is completed only by bending the carpet and fitting the locking tool to the locking clip, the assembling work is greatly simplified. Since the latch is a member with a simple cross-sectional shape, it can be manufactured at low cost by simple extrusion molding. By appropriately selecting the cross-sectional shape, the bending rigidity is increased and the carpet bent portion is formed linearly. can do.
By making the locking member approximately the same length as the slide rail, the above-described flatness can be secured over the entire length of the slide rail. By providing the concave groove, the carpet can be easily bent.
