Description

  The present invention relates to an interior material for a transport aircraft and a method for installing the interior material.

Conventionally, a raising material and a footrest (tibia pad) arranged on a floor of a seat are known as interior parts of an automobile.
FIG. 14 shows a rear seat portion of a conventional automobile compartment 20. A carpet 22 is laid on the upper surface of the floor 21 on the rear seat side in the compartment 20. Depending on the type of passenger car, the lower part of the door opening is shown. The side sill 24 located on the floor is higher than the floor surface in the room. In such a vehicle, the rear seat occupant must move his / her foot across the side sill 24 when getting on and off. By increasing the height, the seating surface is set high for the purpose of obtaining a forward view with a feeling of opening. In such a case, designing a floor with a different height for each vehicle type requires a very large number of manufacturing steps.

Therefore, the conventional floor 21 is used as it is, and a raising method 25 such as a urethane pad is placed on the upper surface of the floor 21 to obtain a high floor surface without changing the vehicle floor structure. As shown in FIG. 15, a foaming resin raising material 25 is placed on the upper surface of the floor 21 at the feet of the passenger in front of the rear seat, and a carpet 22 is laid on the raising material 25 (see, for example, Patent Document 1). ). As a result, a high floor surface is obtained while using a common floor for each vehicle type.
Further, a tibia pad made of foamed resin may be disposed in the passenger compartment as a footrest for an occupant of the front seat (see, for example, Patent Document 2).

  In the case of Patent Document 1, the member main body of the raising member is mounted in the vehicle interior, but the member main body may be rubbed against the vehicle interior (metal vehicle main body) due to vibration while the automobile is running, and noise may be generated. There is. Therefore, a cloth body such as a felt is attached to the bottom surface of the main body at a contact point with the bottom wall of the passenger compartment, wrapped with a non-woven fabric, fastened with a tape, or simply pasted with a gum tape. In other words, cloths, non-woven fabrics, and gummed tapes were used as cushioning materials to suppress noise caused by friction between the member main body and the bottom wall. In addition, the buffer material was similarly affixed on the bottom face also about the tibia pad currently disclosed by patent document 2. FIG.

JP 2000-280809 A JP 2007-98964 A

  However, in Patent Document 1, when a felt or the like is attached as a cloth body to the member body of the raising member 25 and the felt is dented with the passage of time or the like, the contact portion between the member body and the floor is changed. There has been a problem that abnormal noise occurs when the component main body comes into contact with the vehicle main body at a location that has not been initially set.

  This invention is made | formed in view of the problem mentioned above, and makes it a subject to provide the installation material of the interior material of a transport aircraft and the interior material which can suppress the noise by friction with a transport aircraft.

In order to achieve the above object, an interior material for a transport aircraft according to the present invention is an interior material for a transport device mounted in a cabin of a transport aircraft, the member body made of foamed resin, and the transport aircraft in the member body A cover sheet that covers a contact portion that contacts the cover, and the cover sheet is a plastic film and is formed into a bag shape provided with a heat seal portion, and the bag-shaped film is in close contact with the member body It is characterized by being the shrink package formed in this way.

  In this invention, the member main body of the interior material of a transport aircraft is covered with the coating sheet which has a buffer property at least a contact part with a transport aircraft. Therefore, even when the member main body is loose in the room due to a gap generated between the member main body and the transport aircraft, the covering sheet rubs against the wall of the transport aircraft, and the foam resin resin member main body directly contacts the transport aircraft wall. Thus, the generation of noise during driving of the transporting machine due to the friction between the member main body and the wall of the transporting machine can be suppressed.

In the present invention, for example, a plastic film can be used to easily form a bag-like film by a heat seal manufacturing method, and the member main body is accommodated therein so that the entire member main body is a bag-like film. The interior material covered with the film can be easily manufactured. And there exists an advantage that a member main body can be reliably accommodated in a bag-shaped film irrespective of the shape of a member main body. That is, at the time of assembling to a transport machine such as an automobile, the bag-like film is not stretched by the concavo-convex shape portion or the like of the member main body, and can be assembled in a state familiar to the shape of the member main body.
Moreover, since the bag-like film is fused by the heat seal manufacturing method, the bag-like film is difficult to come off from the member main body to be accommodated, and thus an interior material excellent in transportability and workability is provided. Can do.

Further, in the present invention, the interior material in which the bag-shaped film is in close contact with the member main body is easily manufactured by shrink processing by heat shrinking the interior material in which the member main body is accommodated in the bag-shaped film. Can do. In this case, the bag-like film is further effectively prevented from shifting or separating from the member main body to be accommodated, so that it is possible to provide an interior material that is more excellent in transportability and workability.
