Description

  The present invention relates to an automobile mat having an excellent displacement prevention function. More specifically, the present invention relates to an automobile mat that can be smoothly adjusted when the automobile mat is to be laid at a predetermined position on a first carpet of an automobile floor.

  Conventionally, a carpet made of pile yarn and a first carpet made of felt are pasted on the floor of an automobile. For this reason, when a car mat is laid on the car mat, the frictional force between the car floor and the car mat is small, so a slight shift occurs each time you get on and off or move your foot. As a result, there was a large deviation, and the automobile mat sometimes deviated greatly from the position where the automobile floor should be originally placed.

  For this reason, conventionally, as shown in FIGS. 24 and 25, for example, as shown in FIGS. 24 and 25, an automobile mat laid on an automobile floor surface enters a first carpet attached to the automobile floor surface on the back side of the mat body. Many proposals have been proposed in which a resin backing 2 is formed on which a plurality of locking projections 3 are formed to lock and prevent the mat from shifting (for example, Patent Documents 1 and 2).

  In recent years, the car mat laid on the driver's seat side shifted greatly to the front side and entered under the brake pedal of the driver's seat, making it impossible to operate the brake. As a result, an accident occurred in the United States, It became a big social problem. As a result of this incident, the displacement of the mats for automobiles has been brought up again, and in the automobile industry as well as the related goods industry, there is an increasing demand to reliably prevent the displacement of the mats for automobiles laid on the automobile floor. .

  On the other hand, as shown in FIGS. 24 and 25, for example, in an automobile mat in which a resin backing 2 having a large number of locking projections 3 formed on the back side of the mat body is attached, the locking projections 3 are omnidirectional. Therefore, when the automobile mat is to be laid at a predetermined position on the first carpet of the automobile floor, the automobile mat is prevented from being displaced in all directions. On the other hand, there was a problem that the position could not be adjusted smoothly. In addition, since the work for laying the car mat on the car floor is bent down, the position adjustment is a complicated work.
