As the carpet-like surface layer material, it is possible to use felt or a felt-like material made by accumulating fibers and adding needle punching, or carpet material made by flocking a cloth-like material made of woven or knitted fibers. . The carpet-like surface member may be one in which the back surface of the carpet is lined with a thermoplastic resin as a backing material. As the backing material, synthetic thermoplastic resins such as polyethylene, ethylene-vinyl acetate copolymer, polypropylene, and polymethyl methacrylate resin can be used. Such backing materials provide shape retention to the carpet fabric. It is preferable that the surface layer member is previously formed into a predetermined shape using a carpet material and a backing material.

The back layer member is integrally molded with foamed polyurethane on the back side of the surface layer member. The back layer member is usually thicker than the surface layer member. The back side of the back layer member is suitable for use on the floor of the car and the side walls of the car.
The backing member has a ventilation passage communicating between each side air outlet and an air duct of the vehicle. The ventilation path can be formed by a groove formed on the back surface of the backing member. Alternatively, a ventilation path may be formed by adhering a lid member such as an adhesive tape to the peripheral edge of the opening so as to cover the opening of the groove. Further, the ventilation path can be formed by a pipe embedded in the backing member. In this case, the pipe can be insert-molded when the back layer member made of foamed polyurethane is foamed and solidified and molded.

Next, a typical manufacturing method of the automobile floor carpet according to the present invention will be explained. In other words, one split mold with a cavity surface corresponding to the floor surface of an automobile and the other split mold with a cavity surface corresponding to the front shape of the surface layer member are used, and the surface layer member is placed on the side of the other split mold. Then, the urethane stock solution is injected into the cavity through the injection port of the mold, and the urethane stock solution is foamed and hardened, thereby integrating the surface layer member and the back layer member. In addition, when the ventilation passage is formed by a groove as described above, if a protrusion is formed on the cavity surface of one of the split molds, the groove can be formed by the protrusion.

[Action and Effect of the Invention] The automotive floor carpet according to the present invention has the following effects:
It is used by laying it on the floor of a car. When installed, the air ducts and air passages of the vehicle are communicated with each other. Then, when the car's heater or car cooler is activated, hot air or cold air is supplied from the car's air duct into the air passage. This hot air or cold air circulates within the air passage and is blown out from each side air outlet, that is, from the sides, front, and rear of the feet of a passenger sitting in the rear seat. Therefore, the occupant's feet can be heated and cooled effectively.

Furthermore, when the pipe forming the ventilation passage is insert-molded and buried in the backing member, the pipe forming the ventilation passage is not exposed from the backing member, so that the appearance is not impaired.
