Description

Description: TECHNICAL FIELD The present invention relates to an antistatic structure for an automobile mat, and more specifically, to prevent dust and dirt from adhering to the automobile mat and to electrostatically charge a human body. The present invention relates to an antistatic structure for an automobile mat, which is designed to prevent

(Prior Art) Conventionally, an automobile mat is commercially available in which a pile made of insulating fibers is driven into a predetermined volume on a base fabric using insulating fibers.

However, since this automobile mat is made of an insulating material, static electricity is easily generated due to friction with the hem of shoes or pants when the automobile is getting on or off or while driving. As a result, the automobile mat is charged with electricity, dust and dirt are easily attached to the mat, and the mat is easily soiled and must be cleaned frequently. In addition, the static electricity generated by friction will charge not only the car mat but also the human body, and when you touch the metal part of the car when getting on or off, the static electricity accumulated in the human body will be suddenly transferred to the metal part. It was grounded and gave a large electric shock to the human body.

Therefore, in order to solve such a problem, it has been proposed that a conductive material is used as a material for an automobile mat to prevent generation of static electricity.

An example of such an automobile mat is Japanese Patent Laid-Open No. 61

As shown in FIG. 5, this automobile mat (1) has a base cloth.
A conductive base fabric (2) is formed by using a conductive fiber (3) for a part of the threads constituting (2), and electrically connected to the vehicle body side at one end of the automobile mat (1). It is equipped with a connection cord (4) for connection.

And, in this car mat (1), the other end of the connection cord (4) is attached to the vehicle body side, and it is caused by friction with the hem of shoes or pants when getting on or off the car or while driving. It is designed to ground static electricity on the vehicle body side.

(Problems to be Solved by the Invention) However, in the automobile mat described in Japanese Patent Laid-Open No. 61-110632, the static electricity generated by the connection cord attached to one end of the automobile mat is grounded on the vehicle body side. Therefore, when the vehicle mat gets on and off, the connecting cord may come off from the vehicle body side, and grounding may not be possible. In addition, JP-A-61
In the vehicle mat described in Japanese Patent Laid-Open No. 110632, it is necessary to provide a mounting component dedicated to ground for mounting the connection cord on the vehicle body side.

The ring is hooked on a hook made of a conductive material and fixed to the vehicle floor surface, and the static electricity introduced to the ring is grounded to the vehicle floor surface through the hook. At the same time, since the ring of the automobile mat is hooked on the hook fixed to the floor surface of the automobile, the displacement of the automobile mat is prevented.
