Abstract

PROBLEM TO BE SOLVED: To provide a bracket mounting method and a vehicular interior material capable of mounting a bracket on a rear surface material which is not adhered to a substrate.SOLUTION: When mounting the bracket 20 on the rear surface material 14 of the vehicular interior material 10 in which the rear surface material 14 is not adhered to a rear surface fiber layer 13, an infrared ray laser LB is applied from an upper surface 22 of the bracket 20 in such a state that the bracket 20 is pushed to the rear surface material 14, and the rear surface material 14 is pushed to the rear surface fiber layer 13. Thus, the bracket 20 and the rear surface material 14 are melted by heat and adhered to the rear surface fiber layer 13. Accordingly, the rear surface material 14 is adhered to the rear surface fiber layer 13 at a bracket mounting position. Therefore, the bracket 20 can be easily mounted to the vehicular interior material 10 in which the rear surface material 14 is not adhered to the rear surface fiber layer 13.

Description

本発明は、車体パネルに取り付けるためのブラケットが取り付けられた車両用内装材に関する。   The present invention relates to a vehicle interior material to which a bracket for attaching to a vehicle body panel is attached.

車両用内装材の車体パネルに対する取付けは、車両用内装材の裏面に取り付けられているブラケットを、車体パネルに設けられているファスナに結合することで行われるのが一般的である。
従来より、接着剤を用いてブラケットを車両用内装材に取り付けるものが知られている（例えば、特許文献１参照）。 The attachment of the vehicle interior material to the vehicle body panel is generally performed by coupling a bracket attached to the back surface of the vehicle interior material to a fastener provided on the vehicle body panel.
Conventionally, what attaches a bracket to an interior material for vehicles using adhesives is known (for example, refer to patent documents 1).

図４に示すように、特許文献１には、天井用の内装材１００に、車体パネルに取り付けるためのブラケット１０１を取り付ける方法が示されている。
すなわち、内装材１００を構成する天井基材１０２の裏面の所定個所に、熱可塑性繊維シート等の裏面材１０３を熱圧着により強く接着して設けておく。そして、この裏面材１０３に、ブラケット１０１をホットメルト接着剤１０４によって取り付ける。 As shown in FIG. 4, Patent Document 1 discloses a method of attaching a bracket 101 for attaching to a vehicle body panel to an interior material 100 for a ceiling.
That is, a back surface material 103 such as a thermoplastic fiber sheet is strongly bonded by thermocompression bonding at a predetermined position on the back surface of the ceiling base material 102 constituting the interior material 100. Then, the bracket 101 is attached to the back material 103 with a hot melt adhesive 104.

これにより、裏面材１０３の熱可塑性成分の溶融物と、ホットメルト接着剤１０４またはブラケット１０１の溶融物とが混合して、強い取付強度が得られる。
なお、天井基材１０２の表側（図４において下側）には、ホットメルトフィルム１０５を介して表皮材１０６が接合されている。 Thereby, the melt of the thermoplastic component of the back material 103 and the melt of the hot melt adhesive 104 or the bracket 101 are mixed to obtain a strong mounting strength.
A skin material 106 is bonded to the front side (the lower side in FIG. 4) of the ceiling base material 102 via a hot melt film 105.

特開平８−２６７６３０号公報（第３図）JP-A-8-267630 (FIG. 3)

前述した特許文献１に記載のブラケット１０１の取付方法のように、接着剤１０４によってブラケット１０１を裏面材１０３取り付ける場合は、裏面材１０３が天井基材１０２に強力に接着している場合には、十分なブラケット接着強度が得られて好適である。
しかしながら、図５（Ａ）に示すように、膜振動による高吸音仕様等の内装材１００の場合には、ブラケット１０１を取り付ける裏面材１０３と天井基材１０２とが接着されておらず、裏面材１０３をあえて撓ませている。 Like the mounting method of the bracket 101 described in Patent Document 1 described above, when the bracket 101 is attached by the adhesive 104, the back material 103 is strongly bonded to the ceiling base material 102. A sufficient bracket adhesive strength is obtained, which is preferable.
However, as shown in FIG. 5A, in the case of the interior material 100 having a high sound absorption specification or the like by membrane vibration, the back surface material 103 to which the bracket 101 is attached and the ceiling base material 102 are not bonded, and the back surface material 103 is intentionally bent.

このような裏面材１０３にブラケット１０１を接着剤１０４によって取り付けると、図５（Ｂ）に示すように、裏面材１０３の撓みにより、ブラケット１０１と天井基材１０２との間の距離Ｄが定まらないため、使用できない。
また、断熱のために裏面材にアルミフィルムを用いる際に、アルミフィルムを防音にも使うために、アルミフィルムの天井基材への貼り付けを部分的にする場合がある。この場合に、緩ませたアルミフィルムにブラケットを取り付ける際にも、前述したように、使用できないという問題がある。 When the bracket 101 is attached to the back surface material 103 with the adhesive 104, the distance D between the bracket 101 and the ceiling base material 102 is not determined by the bending of the back surface material 103, as shown in FIG. Therefore, it cannot be used.
Moreover, when using an aluminum film for a back surface material for heat insulation, in order to use an aluminum film also for soundproofing, affixing to the ceiling base material of an aluminum film may be made partially. In this case, when the bracket is attached to the loosened aluminum film, there is a problem that it cannot be used as described above.

そこで、本発明は、上記問題点を解決するために、基材と裏面材とが接着されていない状態の裏面材にブラケットを取り付けた車両用内装材を提供することにある。   Therefore, in order to solve the above problems, the present invention is to provide a vehicle interior material in which a bracket is attached to a back surface material in a state where the base material and the back surface material are not bonded.

上記課題を解決するために、本発明に係る車両用内装材は、少なくとも表皮材、基材、裏面繊維層および裏面材を積層して有するとともに、前記裏面材が前記裏面繊維層に接着されていない車両用内装材であって、前記車両用内装材を車体パネルに取り付けるためのブラケットを、前記裏面材に押し付けた状態で、赤外線レーザにより前記ブラケットの取付面および前記裏面材を加熱溶融して前記裏面繊維層に溶着したものである。   In order to solve the above problems, an interior material for a vehicle according to the present invention has at least a skin material, a base material, a back fiber layer, and a back material laminated, and the back material is bonded to the back fiber layer. No vehicle interior material, with the bracket for attaching the vehicle interior material to a vehicle body panel being pressed against the back surface material, the mounting surface of the bracket and the back surface material are heated and melted by an infrared laser. It is welded to the back fiber layer.

この構成によれば、裏面材が裏面繊維層に接着されていない車両用内装材の裏面材にブラケットを取り付ける際に、ブラケットを裏面材に押し付けて裏面材を裏面繊維層に押し付けた状態で、ブラケットの上面から赤外線レーザを照射する。
これにより、ブラケットおよび裏面材を加熱溶融して、裏面繊維層に溶着させるので、ブラケット取付位置においては、裏面材は裏面繊維層に接着されることになり、裏面材が裏面繊維層に接着されていない車両用内装材にでも、ブラケットを所定の位置に強固に取り付けることができる。 According to this configuration, when attaching the bracket to the back surface material of the vehicle interior material in which the back surface material is not bonded to the back surface fiber layer, the bracket is pressed against the back surface material and the back material is pressed against the back surface fiber layer. Irradiate an infrared laser from the upper surface of the bracket.
As a result, the bracket and the back material are heated and melted and welded to the back fiber layer. Therefore, at the bracket mounting position, the back material is bonded to the back fiber layer, and the back material is bonded to the back fiber layer. The bracket can be firmly attached to a predetermined position even on a vehicle interior material that is not.

上記構成において、前記裏面材が、アルミを蒸着した通気止めフィルムであるものである。   The said structure WHEREIN: The said back surface material is a ventilation film which vapor-deposited aluminum.

この構成によれば、裏面材がアルミを蒸着した通気止めフィルムであるので、防音とともに断熱を図ることができる。   According to this configuration, since the back material is a ventilation barrier film on which aluminum is vapor-deposited, heat insulation can be achieved together with soundproofing.

本発明によれば、ブラケットおよび裏面材を加熱溶融して裏面繊維層に溶着させるので、ブラケット取付位置においては、裏面材は裏面繊維層に接着されることになり、裏面材が裏面繊維層に接着されていない車両用内装材にでも、容易にブラケットを取り付けることができるという効果がある。   According to the present invention, since the bracket and the back surface material are heated and melted and welded to the back surface fiber layer, the back surface material is bonded to the back surface fiber layer at the bracket mounting position, and the back surface material is bonded to the back surface fiber layer. There is an effect that the bracket can be easily attached even to the vehicle interior material that is not bonded.

以下、添付図面を参照して、本発明を実施するための形態（以下、実施形態）について詳細に説明する。なお、実施形態の説明の全体を通して同じ要素には同じ番号を付している。   DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same number is assigned to the same element throughout the description of the embodiment.

図１に示すように、本発明にかかる車両用内装材１０は、天井材等の車体パネル（図示省略）に取り付けるためのブラケット２０を、裏面に取り付けたものである。   As shown in FIG. 1, a vehicle interior material 10 according to the present invention has a bracket 20 attached to a rear surface of a vehicle body panel (not shown) such as a ceiling material.

車両用内装材１０は、少なくとも表皮材１１、基材１２、裏面繊維層１３、非通気性の裏面材１４、表面繊維層１５及びスパンレース不織布１６を積層して有する。表皮材１１には、不織布、織布、ニット等公知のものを用いることができる。基材１２は例えばウレタンで構成され、裏面繊維層１３はイソシアネートを塗布したガラス繊維で構成することができる。ここでは、表皮材１１と基材１２との間に、裏面繊維層１３と同じ材質の表面繊維層１５を有する。
裏面材１４は、通気止めフィルムの表面にアルミを蒸着させたアルミフィルムである。スパンレース不織布１６は、ガラス繊維からなる裏面繊維層１３とアルミフィルムからなる裏面材１４の間に挟まれるものであって、５０ｇ／ｍ２程度のものを用いることができる。
通常は表皮材１１、表面繊維層１５、基材１２、裏面繊維層１３、裏面材１４を順に積層し型温１４０〜１５０℃のホットプレスで圧着する。この時に裏面繊維層１３に塗布・含浸されたイソシアネートが溶融し裏面繊維層１３に隣接する夫々の層との接着をする。ただし、裏面材１４が膜振動の役目を果たす為には裏面繊維層１３と接着しない部分（例えばトリム外周と開口周縁部以外）を設ける必要があり、この部分に型温では溶融しないスパンレース不織布１６を両者間に挟んで成形することにより、裏面繊維層１３とスパンレース不織布１６は接着されるが、スパンレース不織布１６と裏面材１４は接着しないので、裏面材１４が基材１２に対して弛むことになる。尚、表皮材１１、基材１２、裏面繊維層１３、裏面材１４は略同じ大きさになる。 The vehicle interior material 10 includes at least a skin material 11, a base material 12, a back fiber layer 13, a non-breathable back material 14, a surface fiber layer 15, and a spunlace nonwoven fabric 16. A known material such as a nonwoven fabric, a woven fabric, or a knit can be used for the skin material 11. The base material 12 is made of urethane, for example, and the back fiber layer 13 can be made of glass fiber coated with isocyanate. Here, a surface fiber layer 15 made of the same material as the back fiber layer 13 is provided between the skin material 11 and the base material 12.
The back material 14 is an aluminum film in which aluminum is vapor-deposited on the surface of the air-blocking film. The spunlace nonwoven fabric 16 is sandwiched between the back fiber layer 13 made of glass fiber and the back material 14 made of an aluminum film, and can be about 50 g / m 2 .
Usually, the skin material 11, the surface fiber layer 15, the base material 12, the back surface fiber layer 13, and the back surface material 14 are laminated | stacked in order, and it crimps | bonds by the hot press with the mold temperature of 140-150 degreeC. At this time, the isocyanate coated and impregnated on the back fiber layer 13 melts and adheres to the respective layers adjacent to the back fiber layer 13. However, in order for the back material 14 to play the role of membrane vibration, it is necessary to provide a portion that does not adhere to the back fiber layer 13 (for example, other than the outer periphery of the trim and the peripheral edge of the opening). The back fiber layer 13 and the spunlace nonwoven fabric 16 are bonded to each other by molding the 16 between the two, but the spunlace nonwoven fabric 16 and the back material 14 are not bonded. It will sag. In addition, the skin material 11, the base material 12, the back surface fiber layer 13, and the back surface material 14 become substantially the same size.

車両用内装材１０が、膜振動による高吸音仕様等の場合には、裏面材１４が振動して車内の音を吸音するため、裏面材１４は内側（図１において下側）に隣接する裏面繊維層１３に接着されていない。
少なくとも、ブラケット２０を取り付ける位置において、裏面材１４は裏面繊維層１３に接着されている必要はない。 When the vehicle interior material 10 has a high sound absorption specification or the like due to membrane vibration, the back material 14 vibrates and absorbs the sound in the vehicle, so the back material 14 is adjacent to the inner side (lower side in FIG. 1). It is not bonded to the fiber layer 13.
At least in the position where bracket 20 is attached, back material 14 does not need to be bonded to back fiber layer 13.

次に、本発明にかかる車両用内装材１０にブラケット２０を取り付ける方法について説明する。
図１に示すように、まず、裏面材１４の外表面１４１（図１において上面）にブラケット２０の取付面２１（図１において下面）を押し付ける。このとき、押さえ治具３０を用いてブラケット２０を裏面材１４に押し付ける。
裏面材１４は、その内側（図１において下側）に隣接する裏面繊維層１３に接着されていないが、押さえ治具３０を用いてブラケット２０を裏面材１４に加圧して押し付けるので、このとき裏面材１４は裏面繊維層１３の所定位置に接する。 Next, a method for attaching the bracket 20 to the vehicle interior material 10 according to the present invention will be described.
As shown in FIG. 1, first, the mounting surface 21 (lower surface in FIG. 1) of the bracket 20 is pressed against the outer surface 141 (upper surface in FIG. 1) of the back material 14. At this time, the bracket 20 is pressed against the back surface material 14 using the holding jig 30.
Although the back surface material 14 is not bonded to the back surface fiber layer 13 adjacent to the inner side (lower side in FIG. 1), the bracket 20 is pressed and pressed against the back surface material 14 using the pressing jig 30. The back material 14 is in contact with a predetermined position of the back fiber layer 13.

次に、ブラケット２０を裏面材１４に押し付けた状態で、ブラケット２０の上面２２からブラケット２０を貫通して裏面材１４に、レーザヘッド３１から赤外線レーザＬＢを照射する。   Next, in a state where the bracket 20 is pressed against the back surface material 14, the bracket 20 is penetrated from the upper surface 22 of the bracket 20, and the back surface material 14 is irradiated with the infrared laser LB from the laser head 31.

ブラケット２０の上面２２における赤外線レーザＬＢ（レーザヘッド３１）の走査パターンＰとしては、図２（Ａ）に示すように、ブラケット２０の外周縁に沿って矩形状に走査することができる。
あるいは、図２（Ｂ）に示すように、十字形状に走査したり、図２（Ｃ）に示すように、対角線状に走査することができる。 The scanning pattern P of the infrared laser LB (laser head 31) on the upper surface 22 of the bracket 20 can be scanned in a rectangular shape along the outer periphery of the bracket 20, as shown in FIG.
Alternatively, it can be scanned in a cross shape as shown in FIG. 2B, or can be scanned in a diagonal line as shown in FIG.

赤外線レーザＬＢは、裏面材１４および裏面繊維層１３まで達することができるが、基材１２には達しない強度とする。
赤外線レーザＬＢにより、ブラケット２０の取付面２１と、裏面材１４の外表面１４１との間で発熱させて、ブラケット２０および裏面材１４の融点まで達する。 The infrared laser LB can reach the back material 14 and the back fiber layer 13 but has a strength that does not reach the substrate 12.
The infrared laser LB generates heat between the mounting surface 21 of the bracket 20 and the outer surface 141 of the back material 14 and reaches the melting point of the bracket 20 and the back material 14.

発熱温度は、ブラケット２０、裏面材１４、スパンレース不織布１６、裏面繊維層１３のいずれも溶融する、例えば２５０℃くらいが望ましい。
これにより、ブラケット２０の取付面２１および裏面材１４が溶融するので、ブラケット２０および裏面材１４は、裏面繊維層１３の表面付近に溶着される。このとき、裏面繊維層１３の表面付近をも，溶融させることが望ましい。 The exothermic temperature is desirably about 250 ° C., for example, where all of the bracket 20, the back material 14, the spunlace nonwoven fabric 16, and the back fiber layer 13 are melted.
Thereby, the mounting surface 21 and the back surface material 14 of the bracket 20 are melted, so that the bracket 20 and the back surface material 14 are welded in the vicinity of the surface of the back surface fiber layer 13. At this time, it is desirable to melt the vicinity of the surface of the back fiber layer 13 as well.

図３には、裏面材１４に溶着させたブラケット２０を取り外した状態が示されている。
図３に示すように、ブラケット２０の取付面２１には、赤外線レーザＬＢの走査パターンに沿って溶着部２３が形成されている。一方、裏面材１４の外表面１４１には、ブラケット２０の溶着部２３に対応する溶着部１４２が形成されており、両溶着部２３，１４２が溶着していたことが分かる。
なお、裏面材１４の溶着部１４２は、裏面材１４の内側（図３において紙面直角方向下側）に積層されている裏面繊維層１３における裏面材１４側の少なくとも表面に溶着している。 FIG. 3 shows a state where the bracket 20 welded to the back material 14 is removed.
As shown in FIG. 3, a welding portion 23 is formed on the mounting surface 21 of the bracket 20 along the scanning pattern of the infrared laser LB. On the other hand, a welded portion 142 corresponding to the welded portion 23 of the bracket 20 is formed on the outer surface 141 of the back material 14, and it can be seen that the welded portions 23 and 142 are welded.
The weld 142 of the back material 14 is welded to at least the surface on the back material 14 side of the back fiber layer 13 laminated inside the back material 14 (lower side in the direction perpendicular to the paper surface in FIG. 3).

なお、ブラケット２０の取付面２１における溶着面積（溶着部２３の面積）は、ブラケット２０の取付面２１の全体面積の少なくとも５％以上、すなわち、５％〜１００％となるように、走査パターンＰを設定するのが望ましい。   In addition, the scanning pattern P is set so that the welding area (the area of the welding portion 23) on the mounting surface 21 of the bracket 20 is at least 5% or more of the entire mounting surface 21 of the bracket 20, that is, 5% to 100%. It is desirable to set.

また、ブラケット２０は全体を白色等の薄い色で形成して赤外線レーザＬＢを透過しやすくするとともに、取付面２１を黒色に着色して赤外線レーザＬＢを吸収しやすくするのが望ましい。
これにより、取付面２１では発熱するが、その他の箇所では赤外線レーザＬＢの影響を受けないようにすることができる。
なお、ブラケット２０の取付面２１の着色は、塗装によることができるが、成形時に２層で構成し、取付面２１を黒色の樹脂で成形することもできる。 Further, it is desirable that the bracket 20 is entirely formed of a light color such as white to facilitate the transmission of the infrared laser LB, and the mounting surface 21 is colored black to facilitate the absorption of the infrared laser LB.
Thereby, although heat is generated on the mounting surface 21, it can be prevented from being affected by the infrared laser LB in other places.
The mounting surface 21 of the bracket 20 can be colored by painting, but it may be formed of two layers at the time of molding, and the mounting surface 21 may be molded with a black resin.

以上説明したことから明らかとなるように、本発明にかかる車両用内装材１０によれば、裏面材１４が裏面繊維層１３に接着されていない車両用内装材１０の裏面材１４にブラケット２０を取り付ける際に、ブラケット２０を裏面材１４に押し付けて裏面材１４を裏面繊維層１３に押し付けた状態で、ブラケット２０の上面２２から赤外線レーザＬＢを照射する。
これにより、ブラケット２０、裏面材１４、スパンレース不織布１６を加熱溶融して裏面繊維層１３を溶着するので、ブラケット取付位置においては、裏面材１４は裏面繊維層１３に接着されることになり、裏面材１４が裏面繊維層１３に接着されていない車両用内装材１０にでも、ブラケット２０を所定の位置に強固に取り付けることができる。 As apparent from the above description, according to the vehicle interior material 10 according to the present invention, the bracket 20 is attached to the back surface material 14 of the vehicle interior material 10 in which the back material 14 is not bonded to the back fiber layer 13. When attaching, the infrared laser LB is irradiated from the upper surface 22 of the bracket 20 in a state where the bracket 20 is pressed against the back surface material 14 and the back surface material 14 is pressed against the back surface fiber layer 13.
Thereby, since the back fiber layer 13 is welded by heating and melting the bracket 20, the back material 14, and the spunlace nonwoven fabric 16, the back material 14 is bonded to the back fiber layer 13 at the bracket mounting position. Even in the vehicular interior material 10 in which the back material 14 is not bonded to the back fiber layer 13, the bracket 20 can be firmly attached to a predetermined position.

また、裏面材１４がアルミを蒸着した通気止めフィルムであるので、防音とともに断熱を図ることができる。   Moreover, since the back surface material 14 is a ventilation stopper film vapor-deposited with aluminum, heat insulation can be achieved with soundproofing.

また、赤外線レーザＬＢは、車両用内装材１０の基材１２まで達しないので、例えばウレタン等により基材１２を形成している場合に、基材１２が熱で劣化するのを防止できる。   Moreover, since the infrared laser LB does not reach the base material 12 of the vehicle interior material 10, for example, when the base material 12 is formed of urethane or the like, the base material 12 can be prevented from being deteriorated by heat.

また、ブラケット２０の取付面２１の面積の少なくとも５％を溶融して融着するので、ブラケット２０を確実に裏面材１４に接着することができる。   Further, since at least 5% of the area of the mounting surface 21 of the bracket 20 is melted and fused, the bracket 20 can be securely bonded to the back surface material 14.

以上、実施形態を用いて本発明を説明したが、本発明の技術的範囲は上記実施形態に記載の範囲には限定されないことは言うまでもない。上記実施形態に、多様な変更または改良を加えることが可能であることが当業者に明らかである。またその様な変更または改良を加えた形態も本発明の技術的範囲に含まれ得ることが、特許請求の範囲の記載から明らかである。   As mentioned above, although this invention was demonstrated using embodiment, it cannot be overemphasized that the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiments. Further, it is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
