パーティションウインド用の開口1aを形成するととも
に、上縁両端に縁飾り材2,2と接合される連接部1b,1bを
形成したものである。FIG. 4 shows a rear corner 1 which is one of the interior parts and a joint structure thereof. The rear corner 1 forms an opening 1a for a rear partition window, and at the both ends of the upper edge thereof, a trimming material 2,2 is formed. The connecting portions 1b, 1b to be joined are formed.

どこの傾向が強い。The interior parts such as the rear corner 1 and the edging material 2 are usually made of a synthetic resin molded body, and the surface is decorated with a textured pattern or the like to give a soft feeling. In order to put them out, many of these interior parts 1 and 2 have been flocked. In particular, this tendency is stronger for higher-class vehicles.

そして、リアコーナ１は、その連接部1b,1bに縁飾り材
2,2の端部が重ね合わされて、両者が取付けられるのが
一般的である。The rear corner 1 is provided with an edging material at the connecting portions 1b, 1b.
It is general that the two ends are overlapped and attached to each other.

いう不具合があった。However, when the interior parts made of resin moldings with flocked surfaces are superposed and joined as described above, for example, as shown in FIG.
When the surface of the edging material 2 is brought into contact with the lower surfaces of 1b and 1b, the tufted hairs 3 of the edging material 2 in this overlapped portion are pressed, and hair collapse A occurs. Therefore, after these interior parts are attached, the interior parts shrink, and especially in the case of a long material such as the trimming material 2, the degree of shrinkage is large, and the part originally hidden on the lower surface of the rear corner 1 also appears on the surface due to aging. ,as a result,
There was a problem that the hair fall portion A was exposed on the surface and the interior appearance was significantly impaired.

《考案の目的》 この考案は、このような事情に鑑みてなされたもので、

The object of the present invention is to keep the surface texture of the interior parts good even if the interior parts are shrunk in the joint structure of the interior parts that have been flocked on the surfaces, and the interior aesthetics are impaired. An object of the present invention is to provide a joint structure for interior parts that does not cause damage.

《考案の構成と効果》 上記目的を達成するために、本考案は、表面に植毛加工

起を相手部品裏面側に当接させたことを特徴とする。<Constitution and effect of device> In order to achieve the above-mentioned object, the present invention provides an interior part joining structure in which interior parts made of synthetic resin moldings with flocked surfaces are superposed and joined together. ,
At the tip of the interior part located on the lower side, a protrusion having a rounded front side surface and a height dimension capable of preventing hair fall is provided, and when mating with the counterpart part located on the upper side, The tip end portion is guided along the front side surface of the projection, and the projection is brought into contact with the back side of the mating component.

すなわち、前記構成によれば、表面に植毛加工を施した
内装部品同士を重ね合せ接合する際、下側に位置する内
装部品の先端に、相手側部品の裏面に当接する突起を設
けたものであるから、従来の如く下側に位置する内装部
品表面と上側に位置する内装部品下面とは突起を除い
て、直接接触することがなく、したがって重ね合せ部に
おいて下側内装部品の表面の植毛が毛倒れすることがな
い。That is, according to the above configuration, when the interior parts that have been subjected to flocking processing on the surfaces are superposed and joined together, the tip of the interior parts located on the lower side is provided with the protrusion that comes into contact with the back surface of the counterpart part. Therefore, as in the prior art, the surface of the lower interior component is not directly contacted with the surface of the interior component located on the lower side and the lower surface of the interior component located on the upper side, except for the protrusions. There is no hair fall.

したがって、内装部品の熱収縮により、重ね合せ部分が
表面に現れたとしても、植毛はほぼ垂直状態に植設され
た当初の状態を維持しているので、表面風合いが何等異
なることなく、従来の不具合を有効に解決することがで
きる。Therefore, even if the superposed portion appears on the surface due to the heat shrinkage of the interior parts, the flocked hair maintains the initial state of being planted in a substantially vertical state, so that the surface texture does not differ at all, and The problem can be effectively resolved.

更に、突起の前側面に丸みをもたせた形状であるため、
内装部品同士を重ね合せ接合する際、この突起がガイド
として機能し、取付作業性が良好なものとなる。Furthermore, since the front side of the protrusion has a rounded shape,
When the interior parts are superposed and joined to each other, these projections function as guides, and the mounting workability becomes good.

《実施例の説明》 以下、本考案に係る内装部品の接合構造の実施例につい
て添付図面を参照しながら詳細に説明する。<< Description of Embodiments >> Hereinafter, embodiments of a joint structure for interior parts according to the present invention will be described in detail with reference to the accompanying drawings.

に防止することができる（第２図参照）。As shown in FIG. 1, in the overlapping portion of the connecting portion 1b of the rear corner 1 and the edging material 2, the tip 2a of the edging material 2 located on the lower side has a height dimension capable of preventing hair fall of the hair transplant. The protrusion 4 is formed, and the tip of the protrusion 4 is in contact with the lower surface of the connecting portion 1b, and a gap corresponding to the size of the protrusion 4 is formed between the lower surface of the connecting portion 1b of the rear corner 1 and the surface of the trimming material 2. Is formed, the pressing force from the rear corner 1 is not applied to the bristles 3 planted on the surface of the border material 2, so that the bristles of the bristles 3 can be reliably prevented (see FIG. 2).

る。In the present embodiment, the protrusions 4 are set at three locations such as the center and both sides, but the tip edge 2a of the edge decoration material 2 may be bent upward and provided in a flange shape. That is, the border material 2
It suffices that it has a function as a spacer that prevents the contact portion 1b of the rear corner 1 from coming into contact with each other. Furthermore, the protrusion 4
The front side surface of the is rounded, and when the connecting portion 1b of the rear corner 1 is fitted to the edge decoration material 2, the projection 4 serves as a guide function, which facilitates the mounting work.

ことがない。If the rear corner 1 and the edging material 2 are joined to each other in this way, for example, when the rear corner 1 or the edging material 2 contracts after the installation due to a change in environmental temperature, a change over time, etc. The degree of shrinkage is great in the case of a long product.), As shown in FIG. 3, the part that was hidden on the lower surface of the rear corner 1 is exposed to the inside of the room. The bristles 3 planted on the surface of 2 maintain a good condition in which they are planted in a substantially vertical state in all parts, so even if the interior parts contract, the interior aesthetics may be impaired. Absent.
