Abstract
Description
本発明は、自動車の車室の床をサイドシルに合わせて高く設定する嵩上げ材、フットレスト用ティビアパッド等を緩衝性を有する袋体で梱包した自動車内装部品に関する。 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.
自動車内装部品として、嵩上げ材、ティビアパッドがある。これらの用途を以下に記載する。
図4は、従来の自動車の車室(3)を示す斜視図であり、図5は、図4の丸印Bで囲んだ部分の拡大斜視図である。車室(3)には、フロア(4)上に左右一対のフロントシート(30)が配設され、その後部にはリアシート(31)が設けられ、フロア(4)上面には、カーペット(5)が敷設されている。
図5に示すように、乗用車の車種によっては、ドア(図示せず)開口部の下部に位置するサイドシル(32)が、室内のフロア(4)面より高いものがあり(車室(3)の右側サイドシル(32)の矢印H参照)、このような車種ではリアシート(31)の乗員は乗降時にサイドシル(32)を跨ぐようにして、足を移動させねばならないという不具合がある。また、リアシート(31)の乗員の視線を高めることにより、開放感のある前方視界を得ることを目的として、座面を高く設定する場合がある。このような場合に、車種毎に専用で高さを違えたフロア(4)を設計すると、非常に多くの製造工数がかかってしまう。
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.
そのため、従来のフロア(4)をそのまま利用し、フロア(4)の上面にウレタンパッド等の嵩上げ材を置くことにより、車両のフロア構造を変更しないで、高いフロア面を得るという方法がとられている。
図6は、図5をX−X線を含む面にて破断し矢視した断面図である。フロントシート(30)とリアシート(31)との間の乗員の足元に、図5に示すようにフロア(4)の上面に発泡樹脂製の嵩上げ材(1)が置かれ、嵩上げ材(1)の上にカーペット(5)が敷設される(例えば、特許文献1参照)。これにより、フロア(4)を各車種で共通化しつつ、高いフロア面を得ている。
また、フロントシート(30)の乗員用のフットレストとして、図7に示すような発泡樹脂製のティビアパッド(6)が車室(3)内に配備される(例えば、特許文献2参照)。
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).
図8は、従来の嵩上げ材(1)の平面図である。嵩上げ材(1)の本体(10)は車室(3)内に装着されるが、自動車走行中の振動により、本体(10)が車室(3)に対して擦れ、異音が発生する虞れがある。
そこで、本体(10)の底面にて、車室(3)の底壁(34)との接触箇所に、フェルト等の布体(2)を取り付けていた。即ち、布体(2)を緩衝材として用い、本体(10)と底壁(33)との摩擦による異音を抑えていた。ティビアパッド(6)についても同様に底面に布体(2)を貼り付けていた。
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.
本体(10)に布体(2)としてフェルトを取り付けて、車室(3)内に装着した状態では、時間の経過と共に、フェルトが凹み、本体(10)が車室(3)に対して沈下する状態が生じた。
即ち、時間の経過と共に、フェルトが凹むことにより、本体(10)とフロア(4)の接触箇所が変化し、当初設定していなかった箇所からの異音が生じた。フェルトは不織布に比して厚いから、沈下量にバラ付きが生じやすく、自動車走行中の異音発生を完全に防止することは難しい。
フェルトに比して薄く、凹み量が少ない不織布を布体(2)として本体(10)の底面に貼り付けた場合であっても、例えば本体(10)の側面と車室(3)の側面が擦れることにより、自動車走行中に異音を生じる虞れがある。
本発明は、自動車内装部品と車室の壁との摩擦による自動車走行中の異音を緩和することにある。また、後記の如く、自動車内装部品の揮発臭、VOC対策も併せて目的とする。
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.
車室内に装着される自動車内装部品(7)は、本体(10)と、緩衝性を有して本体(10)全体を覆う袋体(8)にて構成される。また、袋体(8)は、通気を遮断するガスバリア性を有する。 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.
自動車内装部品の本体(10)は、全体が緩衝性を有する袋体(8)にて覆われる。従って、本体(10)と車室(3)との間に生じた隙間によって、本体(10)が車室(3)内でガタ付いた場合でも、袋体(8)が車室(3)の壁と擦れ、本体(10)が直接に車室(3)の壁と擦れることはないから、本体(10)と車室(3)の壁との摩擦による自動車走行中の異音を緩和することができる。
また、本体(10)は揮発臭を発する合成樹脂から成形されることが多いが、袋体(8)はガスバリア性が高いから、本体(10)の揮発臭が袋体(8)の外に漏れることを防止することができる。また、近年、環境対策の観点から揮発性有機化合物(VOC)の発散を規制することが求められているが、本体(10)全体を袋体(8)にて覆うことにより、VOCの発散規制にも効果がある。
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.
以下、本発明の一実施例を図を用いて詳述する。
図1は、本例に於ける自動車内装部品、具体的には嵩上げ材(1)の平面図である。尚、以下では説明の便宜上、自動車内装部品として、嵩上げ材(1)を例示するが、ティビアパッド(6)でもよい。
嵩上げ材(1)は発泡性の合成樹脂、例えば発泡性ポリスチレン系樹脂、スチレン改質ポリエチレン系樹脂(具体的には、積水化成品工業株式会社製の商品名:ピオセラン(登録商標))等にて成形される。嵩上げ材(1)の厚みは、1−20cmであり、嵩上げすべき車種によって厚さが決定される。また、出願人は、発泡樹脂として原料粒子を50倍に予備発泡して得られた発泡樹脂ビーズを用いることを想定しているが、この倍率に限定されない。
また、発泡樹脂ビーズを構成する樹脂としては、スチレン改質ポリエチレン系樹脂(具体的には積水化成品工業株式会社製:商品名:ピオセラン(登録商標))、ポリスチレン、ハイインパクトポリスチレン、スチレン−エチレン共重合体等のポリスチレン系樹脂、ポリエチレン、ポリプロピレン等のポリオレフィン系樹脂が挙げられ、これら合成樹脂の混合物やモノマーの共重合体も使用することができる。
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.
図2は、嵩上げ材(1)を袋体(8)にて梱包した自動車内装部品(7)の斜視図、図3は、図2の自動車内装部品(7)をA−A線を含む面にて破断し矢視した断面図である。嵩上げ材(1)の本体(10)は、全体がポリエチレン袋、ビニール袋等の緩衝性があり且つガスバリア性の高い袋体(8)にて梱包され、該袋体(8)は、クラフトテープ(80)による接着、又は輪ゴム(図示せず)による結束にて嵩上げ材(1)に取り付けられる。嵩上げ材(1)は、袋体(8)に梱包された自動車内装部品(7)の状態で車室(3)内に取り付けられる。尚、袋体(8)の接着具はクラフトテープに、結束具は輪ゴムに夫々限定されず、例えば袋体(8)はクリップ等で留められてもよい。
嵩上げ材(1)の本体(10)は、全体が緩衝性を有する袋体(8)にて覆われる。従って、本体(10)と車室(3)との間に生じた隙間によって、本体(10)が車室(3)内でガタ付いた場合でも、袋体(8)が車室(3)の壁と擦れ、本体(10)が直接車室(3)の壁と擦れることはないから、本体(10)と車室(3)の壁との摩擦による自動車走行中の異音の発生を緩和することができる。
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.
また、嵩上げ材(1)は発泡性ポリスチレン系樹脂等にて成形されるから、揮発臭を発生し易い。嵩上げ材(1)の車室(3)への取付け時には、この揮発臭が残存していることがある。本例にあっては、嵩上げ材(1)の本体(10)全体がガスバリア性の高い袋体(8)にて覆われて、接着具又は結束具により塞がれているから、揮発臭が袋体(8)の外に漏れることを防止することができる。従って、自動車の製造工程に於いて、嵩上げ材(1)を車室(3)に取り付ける際の作業性も改善することができる。
更に、近年、環境対策の観点から揮発性有機化合物(VOC)の発散を規制することが求められているが、本体(10)全体を袋体(8)にて覆うことにより、VOCの発散規制にも効果がある。
従って、本体(10)と車室(3)の壁との摩擦による自動車走行中の異音の発生を緩和する目的だけであれば、通気性のある、例えば不織布製の袋体(8)を用いることができるが、揮発臭及びVOCの発散規制対策であれば、通気性のある袋体(8)を用いるのは効果は薄い。
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.
上記実施例の説明は、本発明を説明するためのものであって、特許請求の範囲に記載の発明を限定し、或は範囲を減縮する様に解すべきではない。又、本発明の各部構成は上記実施例に限らず、特許請求の範囲に記載の技術的範囲内で種々の変形が可能であることは勿論である。 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.
