Description

  The present invention relates to an automobile interior part in which a raising member, a footrest tibia pad, and the like that are set high in accordance with a side sill are packed in a bag having cushioning properties.

Car interior parts include raised materials and tibia pads. These uses are described below.
FIG. 4 is a perspective view showing a passenger compartment (3) of a conventional automobile, and FIG. 5 is an enlarged perspective view of a portion surrounded by a circle B in FIG. In the passenger compartment (3), a pair of left and right front seats (30) are provided on the floor (4), a rear seat (31) is provided at the rear thereof, and a carpet (5) is provided on the upper surface of the floor (4). ) Is laid.
As shown in FIG. 5, depending on the type of passenger car, the side sill (32) located at the lower part of the door (not shown) opening is higher than the floor (4) of the room (vehicle compartment (3) The right side sill (32) has an arrow H on the right side sill (32). In such a vehicle type, the passenger in the rear seat (31) must move his / her foot so as to straddle the side sill (32) when getting on and off. Further, there is a case where the seating surface is set high for the purpose of obtaining a forward view with a feeling of opening by increasing the line of sight of the occupant of the rear seat (31). In such a case, designing a floor (4) that is dedicated for each vehicle type and has a different height would require a very large number of manufacturing steps.

For this reason, the conventional floor (4) is used as it is, and a high floor surface is obtained without changing the vehicle floor structure by placing a raising material such as a urethane pad on the upper surface of the floor (4). ing.
6 is a cross-sectional view of FIG. 5 taken along the plane including the line XX and viewed from the direction of the arrow. As shown in FIG. 5, a foaming resin raising material (1) is placed on the upper surface of the floor (4) at the foot of the occupant between the front seat (30) and the rear seat (31). A carpet (5) is laid on the top (see, for example, Patent Document 1). As a result, the floor (4) is shared by each vehicle type, and a high floor surface is obtained.
Further, as a footrest for an occupant of the front seat (30), a tibia pad (6) made of foamed resin as shown in FIG. 7 is provided in the passenger compartment (3) (see, for example, Patent Document 2).

FIG. 8 is a plan view of a conventional raising material (1). The main body (10) of the raising material (1) is mounted in the passenger compartment (3), but the main body (10) is rubbed against the passenger compartment (3) due to vibration while the automobile is running, and noise is generated. There is a fear.
Therefore, a cloth body (2) such as felt is attached to the bottom surface of the main body (10) at the contact point with the bottom wall (34) of the passenger compartment (3). That is, the cloth body (2) was used as a cushioning material, and abnormal noise due to friction between the main body (10) and the bottom wall (33) was suppressed. For the tibia pad (6), the cloth body (2) was similarly attached to the bottom surface.

JP 2000-280809 A JP 2007-98964 A

When the felt is attached to the main body (10) as the cloth body (2) and the felt is attached in the passenger compartment (3), the felt will be recessed with time, and the main body (10) will be in relation to the passenger compartment (3). A state of sinking occurred.
That is, with the passage of time, the felt was recessed, so that the contact location between the main body (10) and the floor (4) changed, and abnormal noise was generated from a location that was not initially set. Since the felt is thicker than the non-woven fabric, the amount of settlement tends to vary, and it is difficult to completely prevent the generation of abnormal noise while the vehicle is running.
Even when a non-woven fabric that is thinner than a felt and has a small amount of dents is attached to the bottom surface of the main body (10) as a cloth body (2), for example, the side surface of the main body (10) and the side surface of the passenger compartment (3) As a result of rubbing, there is a risk that an abnormal noise may be generated while the vehicle is running.
An object of the present invention is to alleviate abnormal noise during traveling of a vehicle due to friction between a vehicle interior part and a wall of a passenger compartment. In addition, as described later, it is also aimed at countermeasures against volatile odor and VOC of automobile interior parts.

  The automobile interior part (7) to be mounted in the passenger compartment is composed of a main body (10) and a bag body (8) having cushioning properties and covering the entire main body (10). The bag (8) has a gas barrier property that blocks ventilation.

The body (10) of the automobile interior part is entirely covered with a bag body (8) having a buffering property. Therefore, even if the main body (10) is loose in the passenger compartment (3) due to the gap generated between the main body (10) and the passenger compartment (3), the bag (8) is not in the passenger compartment (3). Because the main body (10) does not directly rub against the wall of the passenger compartment (3), the noise from the vehicle running due to the friction between the main body (10) and the inner wall of the passenger compartment (3) is mitigated. can do.
The main body (10) is often molded from a synthetic resin that emits a volatile odor. However, since the bag (8) has a high gas barrier property, the volatile odor of the main body (10) is outside the bag (8). Leakage can be prevented. In recent years, it has been required to regulate the emission of volatile organic compounds (VOC) from the viewpoint of environmental measures, but by covering the entire body (10) with a bag (8), regulation of the emission of VOCs. Is also effective.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view of an automobile interior part, specifically, a raising material (1) in this example. In the following, for the convenience of explanation, the raising material (1) is illustrated as an automobile interior part, but a tibia pad (6) may be used.
The raising material (1) can be used for foaming synthetic resins such as foamable polystyrene resins, styrene modified polyethylene resins (specifically, trade name: PIOCERAN (registered trademark) manufactured by Sekisui Plastics Co., Ltd.), etc. To be molded. The thickness of the raising material (1) is 1-20 cm, and the thickness is determined by the vehicle type to be raised. Moreover, although the applicant assumes using the foamed resin bead obtained by pre-foaming raw material particles 50 times as a foamed resin, it is not limited to this magnification.
As the resin constituting the foamed resin beads, styrene-modified polyethylene resin (specifically, Sekisui Plastics Co., Ltd. product name: PIOCELAN (registered trademark)), polystyrene, high impact polystyrene, styrene-ethylene. Examples thereof include polystyrene resins such as copolymers, and polyolefin resins such as polyethylene and polypropylene. Mixtures of these synthetic resins and copolymers of monomers can also be used.

FIG. 2 is a perspective view of the automobile interior part (7) in which the raising material (1) is packed in the bag body (8), and FIG. 3 is a view including the AA line of the automobile interior part (7) of FIG. FIG. The main body (10) of the raising material (1) is entirely packed in a bag body (8) having a cushioning property and a high gas barrier property such as a polyethylene bag and a plastic bag, and the bag body (8) is made of craft tape. It is attached to the raising material (1) by adhesion by (80) or bundling by a rubber band (not shown). The raising material (1) is mounted in the passenger compartment (3) in the state of an automobile interior part (7) packed in a bag (8). Note that the adhesive of the bag (8) is not limited to craft tape, and the binding tool is not limited to a rubber band. For example, the bag (8) may be fastened with a clip or the like.
The main body (10) of the raising material (1) is entirely covered with a bag body (8) having cushioning properties. Therefore, even if the main body (10) is loose in the passenger compartment (3) due to the gap generated between the main body (10) and the passenger compartment (3), the bag (8) is not in the passenger compartment (3). Because the main body (10) does not rub against the wall of the passenger compartment (3) directly, the noise between the main body (10) and the passenger compartment (3) can be generated. Can be relaxed.

Further, since the raising material (1) is molded from an expandable polystyrene resin or the like, it tends to generate a volatile odor. When the raising material (1) is attached to the passenger compartment (3), this volatile odor may remain. In this example, the entire body (10) of the raising material (1) is covered with a bag (8) having a high gas barrier property, and is closed with an adhesive or a binding tool. It is possible to prevent leakage from the bag body (8). Therefore, in the automobile manufacturing process, workability when the raising material (1) is attached to the passenger compartment (3) can also be improved.
Furthermore, in recent years, it has been required to regulate the emission of volatile organic compounds (VOC) from the viewpoint of environmental measures, but by covering the entire body (10) with a bag (8), the emission regulation of VOC is restricted. Is also effective.
Therefore, for the purpose of alleviating the generation of abnormal noise while the vehicle is running due to the friction between the main body (10) and the compartment (3), the bag body (8) made of non-woven fabric, for example, is permeable. Although it can be used, it is less effective to use the air-permeable bag body (8) as long as it is a measure to regulate the emission of volatile odor and VOC.

  The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. In addition, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.
