Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an automobile mat disposed in the passenger compartment of an automobile, and particularly to an automobile mat formed by planting a large number of threads on a base fabric. It is something.

(Prior art) Automotive mats made by implanting threads into this type of base fabric can create a luxurious atmosphere in the interior of the vehicle, and can also provide a good feeling when you put your feet on it. On the other hand, it has the disadvantage that it gets dirty easily. This contamination is caused by the accumulation of dirt and dust, which is exacerbated by the buildup of static electricity on the car mats. In particular, if the base fabric of the automobile mat is lined with a synthetic resin material or the like, static electricity is likely to accumulate in this type of automobile mat. Static electricity on automobile mats is thought to be mainly generated by friction of the upper surface of the automobile mat with shoes or the like. Since this friction occurs frequently while driving a car, the generation of static electricity is an unavoidable phenomenon.

As a conventional technology to solve this problem, for example, Japanese Utility Model Application Publication No. 60-3700 describes a ``static elimination mat for automobiles''.
is proposed. This car's static eliminator is
According to the description of the claims for the utility model registration in the above publication, it is stated that ``a static electricity eliminator whose back is reinforced and includes or does not include a conductive member in which a group of fibers containing conductive fibers are woven into a base fabric and one end is grounded. In the mat, the fiber group includes a small number of conductive fibers and has a U-shape, and the upper two ends of the U-shape penetrate the base fabric and protrude like needles to the upper surface of the base fabric. The bottom part of the shape is configured to be on the lower surface side of the base fabric, and a conductive wire material is sandwiched in contact with the lower surface of the base fabric, and a back reinforcing material is attached, and one end of the conductive wire material is connected to the automobile body with a conductive wire. Although this "static elimination mat" may be sufficient in terms of removing static electricity, it is not possible to position and fix the "static elimination mat" itself to the automobile body. .

In other words, with this type of automotive mat, if it is not firmly fixed to the car body before "static charge removal" is performed, not only will the "conductor wire" be broken, but also ,
This means that the automobile mat must be constantly repositioned to its proper position.

(Problem that the invention aims to solve) This invention was made in view of the above-mentioned circumstances.
The problem to be solved is the imperfection in removing static electricity and preventing misalignment in conventional mats for automobiles.

An object of the present invention is to provide a mat for an automobile that prevents the accumulation of static electricity, prevents dust from adhering to the mat, and can completely prevent misalignment.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by the present invention are as follows. In this automobile mat, a part of the backing material is extended toward the vehicle body side of the automobile, and a conductor having electrical conductivity is integrally formed on the extended portion of the backing material, By connecting one end of the conductor to a part of the base fabric and connecting the other end of the conductor to the vehicle body side, the vehicle mat and the vehicle body can be electrically connected. An automobile mat characterized by the following features:

(Operation of the invention) By doing as described above, the base fabric 11 (or thread 12) of the mat 10 and the automobile body are electrically connected through the conductor 20. As a result, even if static electricity is generated on the mat 10, the static electricity is immediately grounded to the vehicle body through the conductor 20. Therefore, even if static electricity is generated, it is not accumulated on the mat 10, and the mat 10 completely eliminates the attraction of dust due to static electricity.

Further, in this mat 10, a part of the backing material 13 constituting the mat 10 is extended to form an extension part 13a, and the mat 10 is fixed on the body step 30 of an automobile by this extension part 13a. Because I did it,
Not only can the position of the mat 10 be prevented from shifting, but also because the conductor 20 is arranged on the extension 13a, the conductor 20 can be reliably protected by the extension 13a. It is something that

(Embodiment) Below, an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 shows a state in which an automobile mat 10 (hereinafter simply referred to as mat) is spread on the floor on the driver's seat side of an automobile. . As shown in FIG. 2, this mat 10 is formed by planting a large number of threads 12 on a base fabric 11 and lining the back side with a backing material 13 such as a vinyl chloride sheet. This mat 10 has a part of the backing material 13 extending from one side end of the base fabric 11, and is fixed on the car body step 30 of the automobile at the extending part 13a. A conductor 20, which will be described later, is integrated into the conductor 20.

As shown in FIG. 3, one end of a conductor 20 is connected to a part of the base cloth 11 of the mat 10. As shown in FIG. The conductor 20 is made by embedding or weaving a conductor into a flexible base material, and is used to electrically connect anything that comes into contact with the surface of the conductor. This conductor 20 is connected to the base cloth 11 as shown in FIG.
(Thread 12) Can be connected by sewing directly onto the thread 12, or can be interposed between the base fabric 11 and the lining material 13 as shown in FIGS. When lining the material 13, it is connected at the same time.

On the other hand, the other end of the conductor 20 is connected to the vehicle body (vehicle body step 3) as shown in FIGS.
0) side. That is, in the mat 10, the extending portion 13a of the mat 10 is attached to the vehicle body step 30 to prevent the mat 10 itself from shifting. This is done by covering the other end with a step plate 31 and fixing it with screws 32. As a result, the conductor 2
0 is electrically connected to the automobile body side via a screw 32.

Note that, as shown in FIG. 5, one end of the conductor 20 may be placed on the back side of the base fabric 11 and sewn to the back side. Alternatively, as shown in FIG. 6, when lining the base cloth 11 with the backing material 13, one end of the conductor 20 is connected between the base cloth 11 and the backing material 13.
The base fabric 11 and the conductor 20 may be connected by disposing them between them and integrally molding the three. In this case, the conductor 20 can also be fixed to the extension part 13a of the backing material 13 at the same time, and the conductor 20 can be firmly fixed to the extension part 13a. Note that if one end of the conductor 20 is attached to the upper surface of the mat 10, this conductor 20 will be attached to the thread 1.
2 does not come into direct contact with the base fabric 11, but since the base fabric 11 and the thread 12 are statically integrated, it is the same as being attached to the base fabric 11.

(Effect of the invention) In summary, in the present invention, as illustrated in each of the above embodiments, a part of the backing material 13 is extended toward the vehicle body side of the automobile, and this backing material 1
A conductor 20 having electrical conductivity is placed on the extension portion 13a of No. 3.
The mat 10
The feature lies in the fact that the mat can be electrically connected to the car body, thereby making it possible to provide an automobile mat that prevents accumulation of static electricity and prevents dust from adhering to it.

Furthermore, according to the automobile mat according to the present invention,
The extending portion 13a of the backing material 13 allows the conductor 20 to be reliably positioned and fixed on the vehicle body side, and the conductor 20 is protected by the extending portion 13a of the backing material 13.
