Description

【０００１】
【発明の属する技術分野】
本発明は、自動車等のドアトリム、リヤサイドトリム、トランクルームトリム、天井材等の車両用内装材に関する。
【０００２】
この種の内装材例えば天井材は、その裏面に車室内に配設するルームランプやマップランプ或いは温度センサ等に連絡するハーネス、ワイヤー或いはパイプからなる補強材等の取付け部品を装着している。
【０００３】
【従来の技術】
従来のこの種の天井材としては、天井材本体の裏面側に配線配管用ガイド溝を一体的に形成して、この配線配管用ガイド溝内にハーネスや補強材等の取付け部品を配設しているもの、或いは、図３に示すように、天井材本体ａの裏面にハーネスｂを這設した後、ハーネスｂの適宜箇所を接着テープｃにより止着して装着するものが知られていた（特許文献１を参照）。
【０００４】
【特許文献１】
実願平1-31718号（実開平2-121453号）のマイクロフィルム(明細書１頁第12行〜5頁１行、第１図)
【０００５】
【発明が解決しようとする課題】
しかしながら、天井材本体の裏面に配線配管用ガイド溝を一体的に形成した場合、成形天井を成形するための成形型に配線配管用ガイド溝を形成するための凸部等を形成する必要があり、この分型代が嵩むことになる。
【０００６】
この点からすると、図２に示すような成形天井材にあっては、天井材本体ａにガイド溝等を形成することなく、平面状のままに成形しておき、ルームランプｅ或いはマップランプｆに接続されるハーネスｂ等の取付け部品を接着テープｃを使用して止着するものである点、成形型の型費を節約することができる。
【０００７】
反面、天井材本体ａの裏面に接着テープｃのみで止着した場合、特に、ハーネスｂを多数束ねた集結部位ｄのような部位では、接着テープｃが、ハーネスの重さに耐えられず天井材本体ａの運搬中等車体取付け前に剥れてしまうおそれがある。
【０００８】
接着テープｃが一旦剥れてしまうと、ハーネスｂ等の取付け部品は、天井材本体ａから離れてしまう。
【０００９】
この状態のまま、天井材本体ａを車体に装着しようとすると、ハーネスｃ等の取付け部品が安定せず、取付け作業を妨げることになる。
【００１０】
これを防止するためには、再び天井材本体ａの車体への取付け前に、例えば車体組立てライン上において、再び接着テープｃを用いてハーネスｂ等の取付け部品を再び止着することになって、非常に面倒な作業を強いることになる。
【００１１】
本発明は、かかる点に鑑み、接着テープを用いてハーネス等の取り付け部品を天井材本体に止着したとしても、接着テープが容易に天井材本体から剥れ難くした車両用成形天井材を提供することを目的としている。
【００１２】
【課題を解決するための手段】
上記目的を達成するために、本発明に係る車両用内装材は、内装材本体の裏面側に、ハーネス等の取付け部品を這設すると共に、取付け部品の適宜箇所を接着テープにより止着して、取付け部品を内装材本体の裏面に装着して構成する場合、接着テープが、フィルム状の樹脂テープの一面側に感圧型接着剤層及び粘着材層を貼合して構成されており、且つ、取付け部品が這設された内装材本体の裏面側に接着テープの感圧型接着層を貼り付けることによって取付け部品を内装材本体の裏面側に仮止着すると共に、接着テープにおける取付け部品を挟んだ両側を超音波溶着等の溶着手段を用いて接着テープの粘着材層を溶融させた後固化させることによって溶着して、取付け部品を内装材本体の裏面に本止めしたことを特徴とする。
【００１３】
本発明によれば、内装材本体の裏面にハーネス等の取付け部品を止着した接着テープを更に超音波溶着等の溶着手段を用いて内装材本体に溶着したことから、接着テープは、内装材本体の運搬中等において、容易に剥れ難く、内装材本体の車体取付け時にハーネス等の取付け部品が離れてしまって、内装材本体の車体への取付け作業の妨げとなるようなことを防止できる。
【００１４】
【発明の実施の形態】
以下、図１を用いて、本発明における実施の形態について説明する。
【００１５】
図１は、本発明に係る実施の形態による車両用内装材である天井材を裏面側から描画した斜視図である。
【００１６】
図１によれば、天井材本体１は、樹脂芯材等からなる剛性のある基材の表面に柔軟な表皮を表装し、車両の天井形状に適合するようにプレス成形等により所定の形状に成形されて構成している。
【００１７】
天井材本体１の裏面には、取付け部品例えばマップランプ或いはルームランプ（いずれも図示せず）に接続するハーネス２或いは３が這設されている。
【００１８】
そして、ハーネス２，３の所定の部位は、天井材本体１を車両に装着する前に予め接着テープ４を用いて、天井材本体１の裏面に止着されている。
【００１９】
また、ハーネス２，３を束ねた集結部位５は、他より長い寸法の接着テープ４ａによって、天井材本体１の裏面一隅に止着されている。
【００２０】
接着テープ４および４ａは、図２に示すように、フィルム状の樹脂テープの一面に例えばアクリル系の感圧型接着材層４1と淡黄色剥離紙等の粘着材層４2とを貼合して構成するものである。
【００２１】
上記のように構成する接着テープ４および４ａを用いて天井材本体１の裏面にハーネス２或いは３を装着するには、天井材本体１の裏面にハーネス２或いは３を這設し或いはハーネス２および３の集結部位５を作成した状態で、接着テープ４および４ａの感圧型接着材層４1を天井材１側となるように貼り付け、ハーネス２或いは３および集結部位５を仮止着しておく。
【００２２】

BACKGROUND OF THE INVENTION
The present invention relates to vehicle interior materials such as door trims, rear side trims, trunk room trims, ceiling materials and the like of automobiles.
[0002]
This type of interior material, for example, a ceiling material, is mounted on the back surface thereof with attachment parts such as a room lamp, a map lamp, a harness that communicates with a temperature sensor or the like, a reinforcing member made of a wire or a pipe.
[0003]
[Prior art]
As a conventional ceiling material of this type, a guide groove for wiring piping is integrally formed on the back side of the ceiling material main body, and mounting parts such as a harness and a reinforcing material are arranged in the guide groove for wiring piping. As shown in FIG. 3, it is known that a harness b is installed on the back surface of the ceiling material main body a, and then an appropriate portion of the harness b is fixed and attached with an adhesive tape c. (See Patent Document 1).
[0004]
[Patent Document 1]
The microfilm of Japanese Utility Model Application No. 1-31718 (Japanese Utility Model Application Publication No.2-121453)
[0005]
[Problems to be solved by the invention]
However, when the wiring pipe guide groove is integrally formed on the back surface of the ceiling material main body, it is necessary to form a convex part or the like for forming the wiring pipe guide groove on the molding die for molding the molding ceiling. This separation cost will increase.
[0006]
From this point, in the molded ceiling material as shown in FIG. 2, the ceiling material body a is formed in a flat shape without forming a guide groove or the like, and the room lamp e or the map lamp f is formed. It is possible to save the mold cost of the mold by fixing the attachment parts such as the harness b connected to the base plate using the adhesive tape c.
[0007]
On the other hand, when only the adhesive tape c is secured to the back surface of the ceiling material body a, the adhesive tape c cannot withstand the weight of the harness, particularly in a part such as a gathering part d where many harnesses b are bundled. There is a risk that the material body a may be peeled off before the vehicle body is mounted, such as during transportation.
[0008]
Once the adhesive tape c is peeled off, the attachment parts such as the harness b are separated from the ceiling material body a.
[0009]
If the ceiling material body “a” is to be mounted on the vehicle body in this state, the mounting parts such as the harness “c” are not stabilized, and the mounting work is hindered.
[0010]
In order to prevent this, before attaching the ceiling material body a to the vehicle body again, the attachment parts such as the harness b are again fastened using the adhesive tape c again on the vehicle body assembly line, for example. , It will be very troublesome work.
[0011]
In view of the above, the present invention provides a molded ceiling material for a vehicle in which the adhesive tape is not easily peeled off from the ceiling material body even if an attachment component such as a harness is fixed to the ceiling material body using the adhesive tape. The purpose is to do.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, an interior material for a vehicle according to the present invention has an attachment part such as a harness provided on the back side of the interior material body, and an appropriate part of the attachment part is secured with an adhesive tape. In the case where the mounting part is mounted on the back surface of the interior material body, the adhesive tape is configured by bonding a pressure-sensitive adhesive layer and an adhesive material layer to one side of the film-like resin tape, and By attaching a pressure-sensitive adhesive layer of adhesive tape to the back side of the interior material body where the mounting parts are installed, the mounting part is temporarily fixed to the back side of the interior material body, and the mounting parts on the adhesive tape are sandwiched. The adhesive parts of the adhesive tape are melted and then solidified by using a welding means such as ultrasonic welding, and both mounting parts are fixed to the back surface of the interior material main body .
[0013]
According to the present invention, the adhesive tape having the attachment material such as the harness attached to the back surface of the interior material main body is further welded to the interior material main body using welding means such as ultrasonic welding. During transportation of the main body and the like, it is difficult to peel off easily, and it is possible to prevent the attachment parts such as the harness from being separated when the interior material body is mounted on the vehicle body and hindering the work of mounting the interior material body to the vehicle body.
[0014]
