Description

車両用クォータウインドウVehicle quota window
　本発明は、車両の分割窓部を構成するクォータウインドウに関する。 The present invention relates to a quarter window that constitutes a split window portion of a vehicle.
　車両の分割窓部を構成するクォータウインドウの一例である、後部ドア窓部を区切って設けられるクォータウインドウでは、意匠性が重視される。例えば、クォータウインドウは、窓部全体とその周辺の車体とが一体的に見えるように、また、窓部全体とその周辺の車体が面一になるように、構成にされる。合わせて、構成の簡素化によるコスト低減および軽量化が求められている。 In a quarter window that is an example of a quarter window that constitutes a split window portion of a vehicle and that is provided by dividing a rear door window portion, designability is emphasized. For example, the quarter window is configured so that the entire window portion and the surrounding vehicle body can be seen integrally, and the entire window portion and the surrounding vehicle body are flush with each other. In addition, there is a demand for cost reduction and weight reduction by simplifying the configuration.
　このような意匠性や構成の簡素化および軽量化を満足する為に、従来技術では、クォータウインドウパネルとクォータウインドウパネル周縁に構成されるフレーム部が、合成樹脂材料により２色成形される。また、特許文献１には、フレーム部が高剛性を有する合成樹脂材料で形成されたクォータウインドウが開示されている。また、合成樹脂製クォータウインドウには、通常傷つき防止の為にその表面に液状のハードコート剤がコーティングされる。 In order to satisfy such designability, simplification of configuration, and weight reduction, in the conventional technique, the quarter window panel and the frame portion formed on the periphery of the quarter window panel are molded in two colors with a synthetic resin material. Patent Document 1 discloses a quarter window in which a frame portion is formed of a synthetic resin material having high rigidity. In addition, a synthetic resin quarter window is usually coated with a liquid hard coat agent on its surface to prevent damage.
特開２００９－２３４９５号公報JP 2009-23495 A
　特許文献１に記載のクォータウインドウを含む従来のクォータウインドウにおいて、ディビジョンバーとして機能するディビジョンバー部と、ドアフレームに嵌着されるシール部が取り付けられたフレーム部とを一体成形するためには、異なる合成樹脂を用いた２色成形が必要である。それ故、コスト高を招くという問題がある。 In the conventional quarter window including the quarter window described in Patent Document 1, in order to integrally form the division bar portion functioning as the division bar and the frame portion to which the seal portion fitted to the door frame is attached, Two-color molding using different synthetic resins is required. Therefore, there is a problem of incurring high costs.
　また、液状のハードコート剤によりクォータウインドウにハードコーティングを施す場合、クォータウインドウの製造過程にハードコート剤塗布工程及び焼付け工程を設ける必要があるので、クォータウインドウの成形サイクルが長くなる。また、ハードコート処理時にほこり等の異物を巻き込み易く、不良率の増加を生じるおそれがある。異物の巻き込みを防止するためにはクリーンルーム内でハードコート剤を塗布すればよいが、この場合は大掛かりな設備が必要で、コスト高を招くという問題がある。 Further, when hard coating is applied to the quarter window with a liquid hard coating agent, it is necessary to provide a hard coating agent coating step and a baking step in the quarter window manufacturing process, and therefore the quarter window molding cycle becomes longer. In addition, foreign matters such as dust are likely to be caught during the hard coating process, which may increase the defective rate. In order to prevent the inclusion of foreign substances, a hard coat agent may be applied in a clean room. However, in this case, a large-scale facility is required, which causes a problem of high costs.
　本発明は上記問題点に鑑みてなされたものであり、意匠性を向上させつつコスト低減を実現できるクォータウインドウを提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a quota window capable of realizing cost reduction while improving design properties.
　本発明のクォータウインドウ（２０）は、合成樹脂製のクォータウインドウパネル（２１）と、前記クォータウインドウパネルの周縁に沿って前記クォータウインドウパネルと一体形成される合成樹脂製のフレーム部（２２）と、未硬化又は半硬化状態にて、前記クォータウインドウパネルおよび前記フレーム部に密着し、前記クォータウインドウパネルと前記フレーム部の一体成形後に紫外線硬化するハードコートフィルム（２３）と、を備える。 The quarter window (20) of the present invention comprises a synthetic resin quarter window panel (21), and a synthetic resin frame portion (22) integrally formed with the quarter window panel along the periphery of the quarter window panel. A hard coat film (23) which is in an uncured or semi-cured state, is in close contact with the quarter window panel and the frame portion, and is ultraviolet-cured after the quarter window panel and the frame portion are integrally formed.
　この場合、前記クォータウインドウパネルを構成する合成樹脂と前記フレーム部を構成する合成樹脂は共に透過性を有し、前記ハードコートフィルムの一部は１色以上の有色部（２３ｂ）を備えるものであるとよい。 In this case, the synthetic resin constituting the quarter window panel and the synthetic resin constituting the frame portion are both permeable, and a part of the hard coat film is provided with one or more colored portions (23b). There should be.
　さらに、前記有色部を備える前記ハードコートフィルムの一部は、フレーム部に対応する部位に設けられ、前記有色部は非透過性の材質で構成されるものであるとよい。
　また、本発明のクォータウインドウは、ドアフレームとの間をシールするシール部（２４）をさらに備えるとよい。そして、前記シール部は、前記フレーム部を構成する合成樹脂より軟らかい軟質樹脂により、前記フレーム部と共に二色成形されるとよい。 Furthermore, it is preferable that a part of the hard coat film including the colored portion is provided in a portion corresponding to the frame portion, and the colored portion is made of an impermeable material.
In addition, the quarter window of the present invention may further include a seal portion (24) that seals between the quarter window and the door frame. And the said seal | sticker part is good to be two-color-molded with the said frame part by the soft resin softer than the synthetic resin which comprises the said frame part.
　また、前記フレーム部は、ガラスラン（２５）を係止する係止部（２２ｇ）がその先端に形成されたディビジョンバー部（２２ａ）を備えるとよい。そして、前記係止部は、前記フレーム部のうち前記係止部以外の部分を構成する合成樹脂より軟らかい軟質樹脂により前記係止部以外の部分と共に二色成形されるものであるとよい。 Further, the frame part may include a division bar part (22a) in which a locking part (22g) for locking the glass run (25) is formed at the tip thereof. And the said latching | locking part is good to be two-color-molded with parts other than the said latching part by soft resin softer than the synthetic resin which comprises parts other than the said latching part among the said frame parts.
　本発明のクォータウインドウによれば、未硬化又は半硬化状態のハードコートフィルムが、合成樹脂製のクォータウインドウパネルと合成樹脂製のフレーム部の表面に転写、インサート等により、密着成形される。そして、一体成形後に紫外線（ＵＶ）照射によりハードコートフィルムが硬化させられる。ハードコートフィルムの硬化によりクォータウインドウ表面の必要硬度が得られる。本発明のクォータウインドウを成形するときに液状のハードコーティング剤を使用していないので、ハードコート剤の塗布工程及び焼付け工程を廃止できる。さらには、ほこり等の異物がクォータウインドウに巻き込まれることが防止され、クリーンルーム等の大型の設備が不要である。よって、成形サイクルの短縮及び設備の小型化が可能であり、コスト低減が図れる。 According to the quarter window of the present invention, an uncured or semi-cured hard coat film is formed on the surface of the synthetic resin quarter window panel and the synthetic resin frame by transfer, insert or the like. And a hard coat film is hardened by ultraviolet-ray (UV) irradiation after integral molding. The required hardness of the quarter window surface is obtained by curing the hard coat film. Since the liquid hard coating agent is not used when the quarter window of the present invention is molded, the hard coating agent application step and the baking step can be eliminated. Furthermore, foreign matter such as dust is prevented from being caught in the quarter window, and a large facility such as a clean room is unnecessary. Therefore, the molding cycle can be shortened and the equipment can be downsized, and the cost can be reduced.
　また、本発明によれば、一部に有色部を備えるハードコートフィルムがクォータウインドウパネルとフレーム部に密着させられる。ハードコートフィルムの有色部を非透過性の材質で構成し、さらに有色部をフレーム部に対応する部位に設けることで、フレーム部の不可視状態が得られる（フレーム部を非透明に構成することができる）。この場合、クォータウインドウパネルとフレーム部とを透過性を有する同一の合成樹脂で一体成形するとともに、一体成形時にハードコートフィルムをクォータウインドウパネルとフレーム部とに密着させ、一体成形後にハードコートフィルムを硬化させることで、クォータウインドウパネルを透明に、フレーム部を非透明に、それぞれ形成することができる。すなわち、クォータウインドウパネルとフレーム部とを合成樹脂により一体成形する際に２色成形を必要としない。また、ハードコートフィルムの一部に設けられた有色部の色を変更することにより、簡単にフレーム部の色を変更することができる。したがって、色及びデザインの自由度が高い。よって、車体の色に合わせたフレーム部を成形することができ、意匠性向上が図れる。 Further, according to the present invention, a hard coat film partially having a colored portion is brought into close contact with the quarter window panel and the frame portion. The invisible state of the frame part can be obtained by configuring the colored part of the hard coat film with a non-permeable material and further providing the colored part in a portion corresponding to the frame part (the frame part can be configured to be non-transparent). it can). In this case, the quarter window panel and the frame portion are integrally formed of the same synthetic resin having transparency, and the hard coat film is brought into close contact with the quarter window panel and the frame portion during the integral molding, and the hard coat film is formed after the integral molding. By curing, the quarter window panel can be formed transparent and the frame portion can be formed non-transparent. That is, the two-color molding is not required when the quarter window panel and the frame portion are integrally molded with the synthetic resin. Moreover, the color of a frame part can be easily changed by changing the color of the colored part provided in a part of hard coat film. Therefore, the degree of freedom in color and design is high. Therefore, the frame part matching the color of the vehicle body can be formed, and the design can be improved.
　また、クォータウインドウとドアフレームとをシールするシール部を、フレーム部を構成する合成樹脂より軟らかい軟質樹脂でフレーム部と共に一体成形（二色成形）することで、車室内への漏水を防ぐためのシール部材をフレーム部と一体で形成することができる。このため、フレーム部と別体のシール部材が不要となり部品点数の低減、形状の簡略化が図れる。 In addition, the seal part that seals the quarter window and the door frame is integrally molded (two-color molding) together with the frame part using a soft resin that is softer than the synthetic resin that constitutes the frame part, thereby preventing leakage into the vehicle interior. The seal member can be formed integrally with the frame portion. For this reason, a separate seal member from the frame portion is not required, and the number of parts can be reduced and the shape can be simplified.
　また、ガラスラン外れ防止のためのガラスラン係止部が、ディビジョンバー部の先端に形成される。この係止部は、フレーム部のうち前記係止部以外の部分を構成する合成樹脂より軟らかい軟質樹脂で、前記係止部以外の部分と共に一体成形（二色成形）される。これにより、工程の簡略化を図ることができる。
　なお、本明細書において、「二色成形」は、異なる複数の樹脂材料を一体的に成形することを意味する。したがって、色の異なる複数の樹脂材料を一体成形することも、「二色成形」であるし、透過性を有する（透明な）樹脂材料と非透過性を有する（有色の）樹脂材料を一体成形することも、「二色成形」である。また、異なる性質を持つ樹脂材料（例えば硬質樹脂材料と軟質樹脂材料）を一体成形することも、「二色成形」である。 Further, a glass run locking portion for preventing the glass run from coming off is formed at the tip of the division bar portion. The locking portion is a soft resin that is softer than the synthetic resin constituting the portion other than the locking portion of the frame portion, and is integrally molded (two-color molding) together with the portion other than the locking portion. Thereby, the process can be simplified.
In the present specification, “two-color molding” means that a plurality of different resin materials are integrally molded. Therefore, integrally molding a plurality of resin materials with different colors is also “two-color molding”, and integrally molding a transparent (transparent) resin material and a non-permeable (colored) resin material. It is also “two-color molding”. In addition, “two-color molding” is to integrally mold resin materials having different properties (for example, a hard resin material and a soft resin material).

A glass run 25 is attached in the guide groove 22e, and the door glass 13 is guided to the guide groove 22e through the glass run 25 so as to be movable up and down.
　図４は、図３の変形例である。図３との構成の違いについて説明する。図４に示されるように、フレーム部２２には、（少なくとも１つ以上の）リブ部２２ｆが形成され、リブ部２２ｆを覆うようにシール部２４が設けられる。シール部２４は、フレーム部２２を構成する合成樹脂より軟らかい軟質樹脂で２色成形によりフレーム部２２と共に一体成形される。シール部２４の側面にスナップ形状部２４ａが形成され、端面に突起形状部２４ｂが形成される。また、ドアフレーム部１２は、その長手方向に沿って延びる係止部１２ａと座面部１２ｂを備える。係止部１２ａと座面部１２ｂは対向するように配置され、係止部１２ａと座面部１２ｂとの間に空間部１２ｃが形成される。 FIG. 4 is a modification of FIG. A difference in configuration from FIG. 3 will be described. As shown in FIG. 4, the frame portion 22 is formed with (at least one or more) rib portions 22f, and a seal portion 24 is provided so as to cover the rib portions 22f. The seal portion 24 is made of a soft resin softer than the synthetic resin constituting the frame portion 22 and is integrally formed with the frame portion 22 by two-color molding. A snap-shaped portion 24a is formed on the side surface of the seal portion 24, and a protrusion-shaped portion 24b is formed on the end surface. Moreover, the door frame part 12 is provided with the latching | locking part 12a and the seat surface part 12b which extend along the longitudinal direction. The locking portion 12a and the seat surface portion 12b are arranged to face each other, and a space portion 12c is formed between the locking portion 12a and the seat surface portion 12b.
　クォータウインドウ２０のシール部２４は、ドアフレーム部１２の空間部１２ｃに圧入される。ドアフレーム部１２の係止部１２ａと座面部１２ｂの間に、クォータウインドウ２０のシール部２４のスナップ形状部２４ａと突起形状部２４ｂが挟まれるように、シール部２４がドアフレーム部１２に密着する。係止部１２ａと座面部１２ｂの間にスナップ形状部２４ａと突起形状部２４ｂが挟まれることによりドアフレーム部１２にクォータウインドウ２０が保持される。また、シール部２４を構成する軟質樹脂の弾性力により車室内空間がシールされ、車室外から車室内への漏水が防止される。 The seal part 24 of the quarter window 20 is press-fitted into the space part 12c of the door frame part 12. The seal portion 24 closely contacts the door frame portion 12 so that the snap-shaped portion 24a and the protrusion-shaped portion 24b of the seal portion 24 of the quarter window 20 are sandwiched between the locking portion 12a and the seat surface portion 12b of the door frame portion 12. To do. The quarter window 20 is held on the door frame portion 12 by sandwiching the snap-shaped portion 24a and the protrusion-shaped portion 24b between the locking portion 12a and the seat surface portion 12b. Further, the vehicle interior space is sealed by the elastic force of the soft resin constituting the seal portion 24, and water leakage from the outside of the vehicle interior to the vehicle interior is prevented.
　図５は、ハードコートフィルム２３に有色部２３ｂを印刷した状態を示す。ハードコートフィルム２３は、透過部２３ａと有色部２３ｂから構成される。有色部２３ｂは非透過性の材質で構成される。有色部２３ｂは、図３及び図４に示されるように、クォータウインドウ２０のフレーム部２２に対応する部位等に設けられる。フレーム部２２が有色部２３ｂで覆われるので、フレーム部２２の内部は視認できない。このためシール部２４及びガラスラン２５を外部から隠すことができる。有色部２３ｂの色、面積等は、自由に設定できる。 FIG. 5 shows a state where the colored portion 23 b is printed on the hard coat film 23. The hard coat film 23 includes a transmission part 23a and a colored part 23b. The colored portion 23b is made of an impermeable material. The colored portion 23b is provided in a portion corresponding to the frame portion 22 of the quarter window 20 as shown in FIGS. Since the frame part 22 is covered with the colored part 23b, the inside of the frame part 22 cannot be visually recognized. For this reason, the seal part 24 and the glass run 25 can be hidden from the outside. The color, area, etc. of the colored portion 23b can be freely set.
　図６は、ディビジョンバー部２２ａの断面拡大図である。ディビジョンバー部２２ａの先端部２２ｇは、フレーム部２２のうち先端部２２ｇ以外の部分を構成する合成樹脂より軟らかい軟質樹脂により、先端部２２ｇ以外の部分とともに２色成形により一体成形される。図６に示されるように、先端部２２ｇを構成する車両前方に開口する断面Ｕ字形状の先端部分が内側に湾曲している。先端部２２ｇは、ガイド溝２２ｅ内にガイドされるガラスラン２５を係止する機能を有する。 FIG. 6 is an enlarged cross-sectional view of the division bar portion 22a. The distal end portion 22g of the division bar portion 22a is integrally formed by two-color molding with a portion other than the distal end portion 22g by a soft resin that is softer than the synthetic resin constituting the portion other than the distal end portion 22g in the frame portion 22. As shown in FIG. 6, the tip portion having a U-shaped cross section that opens to the front of the vehicle and that forms the tip portion 22 g is curved inward. The distal end portion 22g has a function of locking the glass run 25 guided in the guide groove 22e.
　図７は、図２におけるVII－VII断面図である。フレーム部２２の下側枠辺部２２ｃには、ベルトモール２６の断面形状に合わせた断面形状を有するベルトモール部２２ｈが形成される。ベルトモール部２２ｈは、フレーム部２２のその他の部分およびクォータウインドウ２１と共に一体成形される。また、ドア本体部１１を挟みこむように、一対のドアパネル係止部２２ｊが形成される。このドアパネル係止部２２ｊがドア本体部１１を係止することにより、クォータウインドウ２０の車両側方方向の移動が規制される。 FIG. 7 is a sectional view taken along line VII-VII in FIG. A belt molding portion 22 h having a cross-sectional shape that matches the cross-sectional shape of the belt molding 26 is formed on the lower frame side portion 22 c of the frame portion 22. The belt molding portion 22h is integrally formed with the other portions of the frame portion 22 and the quarter window 21. Moreover, a pair of door panel latching | locking part 22j is formed so that the door main-body part 11 may be inserted | pinched. When the door panel locking portion 22j locks the door main body 11, the movement of the quarter window 20 in the vehicle lateral direction is restricted.
　ベルトモール２６は、ドアガラス１３の下部に設けられる部分とクォータウインドウ２０の下部に設けられる部分とに分割された構成とすることもできる。この場合、ドアガラス１３の下部にベルトモール２６が配設され、クォータウインドウ２０の下部にフレーム部２２のベルトモール部２２ｈが配設されるように構成することができる。尚、ベルトモール部２２ｈ及びドアパネル係止部２２ｊは、フレーム部２２のうちベルトモール部２２ｈおよびドアパネル係止部２２ｊ以外の部分を構成する合成樹脂より軟らかい軟質樹脂で、２色成形によりこれら以外の部分と共に一体成形されるように構成されていてもよい。 The belt molding 26 may be divided into a portion provided below the door glass 13 and a portion provided below the quarter window 20. In this case, the belt molding 26 can be disposed below the door glass 13, and the belt molding 22 h of the frame portion 22 can be disposed below the quarter window 20. The belt molding portion 22h and the door panel locking portion 22j are soft resins that are softer than the synthetic resin constituting the frame portion 22 other than the belt molding portion 22h and the door panel locking portion 22j. You may be comprised so that it may be integrally molded with a part.
　図８Ａおよび図８Ｂは、ベルトモールをベルトモール２６とベルトモール部２２ｈとに分割して構成した場合に、クォータウインドウ２０のベルトモール部２２ｈとベルトモール２６とを嵌合させる部位を示す図である。図８Ａに示すように、クォータウインドウ２０の下側枠辺部２２ｃに凸形状のフレーム側嵌合部２２ｋがフレーム部２２のその他の部分と共に一体的に形成される。また、フレーム部２２のベルトモール部２２ｈに凸形状のガイド部２２ｍがフレーム部２２のその他の部分と共に一体的に形成される。また、図８Ｂに示すように、ベルトモール２６には、凹形状のベルトモール側嵌合部２６ａが形成される。フレーム側嵌合部２２ｋとベルトモール側嵌合部２６ａは、嵌め合わすことができるような形状に、それぞれ形成される。また、ガイド部２２ｍは、ベルトモール２６の内側の面２６ｂに沿うことができるような形状に形成された外表面を持つ。フレーム側嵌合部２２ｋとベルトモール側嵌合部２６ａを嵌合させ、且つ、ガイド部２２ｍが、ベルトモール２６の内側の面２６ｂに挿入されることで、２分割されたベルトモール２６に一体感を与えるように、ベルトモール２６とベルトモール部２２ｈが嵌合する。 FIG. 8A and FIG. 8B are diagrams illustrating a portion where the belt molding portion 22h of the quarter window 20 and the belt molding 26 are fitted when the belt molding is divided into the belt molding 26 and the belt molding portion 22h. is there. As shown in FIG. 8A, a convex frame-side fitting portion 22 k is integrally formed with the other portions of the frame portion 22 on the lower frame side portion 22 c of the quarter window 20. In addition, a convex guide portion 22 m is integrally formed with the other portions of the frame portion 22 on the belt molding portion 22 h of the frame portion 22. Further, as shown in FIG. 8B, the belt molding 26 is formed with a concave belt molding side fitting portion 26a. The frame side fitting portion 22k and the belt molding side fitting portion 26a are respectively formed in shapes that can be fitted together. The guide portion 22m has an outer surface formed in a shape that can be along the inner surface 26b of the belt molding 26. The frame side fitting portion 22k and the belt molding side fitting portion 26a are fitted, and the guide portion 22m is inserted into the inner surface 26b of the belt molding 26, so that the belt molding 26 divided into two is aligned. The belt molding 26 and the belt molding portion 22h are fitted so as to provide a bodily sensation.
　尚、フレーム側嵌合部２２ｋとベルトモール側嵌合部２６ａの嵌め合い形状は、図８に示す円形状に限定されない。 In addition, the fitting shape of the frame side fitting part 22k and the belt molding side fitting part 26a is not limited to the circular shape shown in FIG.
　上記のように構成されたクォータウインドウ２０では、以下のような利点が得られる。 The quarter window 20 configured as described above provides the following advantages.
　合成樹脂製のクォータウインドウ２０の傷つき防止のためのハードコート処理がハードコートフィルム２３を用いて行われる。ハードコートフィルム２３は、クォータウインドウパネル２１及びフレーム部２２の表面に未硬化又は半硬化状態にて、クォータウインドウパネル２１とフレーム部２２との一体成形時に密着成形される。密着成形後にＵＶ照射によりハードコートフィルム２３が硬化される。これにより必要な硬度が得られる。したがって、従来技術のように、液状のハードコート剤を使用しないため、成形サイクルの長い塗布工程及び焼付け行程が不要である。さらには、クォータウインドウパネル２１とフレーム部２２との一体成形時に成形型内に未硬化または半硬化状態のハードコート剤をインサートしておくことにより、一体成形時に同時にハードコートフィルムがクォータウインドウパネル２１およびフレーム部２２に密着形成される。型内でハードコートフィルムが密着形成されるので、ほこり等の異物がクォータウインドウ２０に巻き込まれることが防止され、クリーンルーム等の大型の設備が不要となる。よって、成形サイクルの短縮、設備の縮小ができ、コストの低減が図れる。 Hard coating treatment for preventing the quarter window 20 made of synthetic resin from being damaged is performed using the hard coating film 23. The hard coat film 23 is formed on the surfaces of the quarter window panel 21 and the frame part 22 in an uncured or semi-cured state when the quarter window panel 21 and the frame part 22 are integrally formed. The hard coat film 23 is cured by UV irradiation after the adhesion molding. This provides the necessary hardness. Therefore, unlike the prior art, since a liquid hard coat agent is not used, an application process and a baking process with a long molding cycle are unnecessary. Furthermore, an uncured or semi-cured hard coat agent is inserted into the mold during integral molding of the quarter window panel 21 and the frame portion 22, so that the hard coat film is simultaneously formed during the integral molding. And is formed in close contact with the frame portion 22. Since the hard coat film is formed in close contact within the mold, foreign matter such as dust is prevented from being caught in the quarter window 20, and a large facility such as a clean room becomes unnecessary. Therefore, the molding cycle can be shortened, the equipment can be reduced, and the cost can be reduced.
　また、ハードコートフィルム２３は、非透過性の有色部２３ｂを備える。この非透過性の有色部２３ｂでクォータウインドウ２０の一部（フレーム部２２等）を覆うことにより、その内部を外部から視認することができないようにすることができる。このようにハードコートフィルム２３に着色機能を持たせたため、クォータウインドウパネル２１とフレーム部２２を透過性を有する同一の樹脂材料で一体成形し、ハードコートフィルム２３でフレーム部２３等を着色することができる。よって、従来技術（例えば特許文献１）のように、有色の合成樹脂材料で構成されるフレーム部２２と無色（透明）の合成樹脂材料で構成されるクォータウインドウパネル２１を２色成形することが不要となり、工程の削減が図れる。 Further, the hard coat film 23 includes an opaque color portion 23b. By covering a part of the quarter window 20 (such as the frame portion 22) with the non-transparent colored portion 23b, it is possible to prevent the inside from being visually recognized from the outside. Thus, since the hard coat film 23 has a coloring function, the quarter window panel 21 and the frame portion 22 are integrally formed of the same resin material having transparency, and the hard coat film 23 is used to color the frame portion 23 and the like. Can do. Therefore, as in the prior art (for example, Patent Document 1), the frame portion 22 made of a colored synthetic resin material and the quarter window panel 21 made of a colorless (transparent) synthetic resin material can be molded in two colors. It becomes unnecessary and can reduce the number of processes.
　また、有色部２３ｂの色、面積等は自由に設定できる。例えば、ベルトモール２６が金属製もしくは、ベルトモール２６の色が金属調の色等であり、クォータウインドウ２０のフレーム部２２と別系色の場合、フレーム部２２のベルトモール部２２ｈの色をベルトモール２６と同色に設定することが可能である。よって、意匠性を損なうことなく、後部ドア１０のベルトラインを２分割し、ドアガラス１３の下部にはベルトモール２６を配置し、クォータウインドウ２０の下部にはフレーム部２２と一体成形されたベルトモール部２２ｈを配置するように構成することができる。従来技術のように、ベルトモール２６をドアガラス１３の下部からクォータウインドウ２０の下部まで設定する必要がなく、ベルトモール２６の端末キャップ及びクォータウインドウ２０下部に配置される部位のトリム加工が不要となり、部品点数の低減及び工程低減が図れる。また、クォータウインドウ２０とベルトモール部２２ｈが一体成形されることにより、車室内への漏水を防止できる。 Also, the color, area, etc. of the colored portion 23b can be freely set. For example, when the belt molding 26 is made of metal, or the color of the belt molding 26 is a metallic color or the like, and is different from the frame portion 22 of the quarter window 20, the color of the belt molding portion 22h of the frame portion 22 is changed to the belt. It is possible to set the same color as the mall 26. Therefore, the belt line of the rear door 10 is divided into two without impairing the design, the belt molding 26 is arranged at the lower part of the door glass 13, and the belt formed integrally with the frame part 22 at the lower part of the quarter window 20. It can comprise so that the molding part 22h may be arrange | positioned. Unlike the prior art, it is not necessary to set the belt molding 26 from the lower part of the door glass 13 to the lower part of the quarter window 20, and the trim processing of the terminal cap of the belt molding 26 and the part arranged under the quarter window 20 becomes unnecessary. The number of parts and the number of processes can be reduced. In addition, since the quarter window 20 and the belt molding portion 22h are integrally formed, water leakage into the vehicle compartment can be prevented.
　さらに、ハードコート処理に伴う塗布工程を廃止できるため、クォータウインドウ２０のシール部２４を構成する軟質樹脂の弾性を確保するために必要であったマスキング工程、ハードコート処理後にシール部２４を成形する等の工程が不要となる。また、クォータウインドウパネル２１とフレーム部２２を、透過性を有する同一の樹脂材料で一体成形することが可能である。さらに、クォータウインドウ２０のシール部２４を、フレーム部２２を構成する合成樹脂より軟らかい軟質樹脂により、フレーム部２２と共に２色成形で一体成形できる。また、シール部２４が型抜き方向にアンダーカット部が形成される構成であっても、軟質樹脂の弾性力を利用した無理抜きによりシール部２４とフレーム部２２とを一体成形することができる。そのためシール部２４の形状を、ドアフレーム部１２の空間部１２ｃに比較的軽い力で圧入することができ、圧入後は、シール部２４が外れにくくなるようなスナップ形状に形成することができる。よって、シール部２４は、クォータウインドウ２０がドアフレーム部１２から外れることを防止する脱落防止機能と、シール部２４を構成する軟質樹脂の弾性力により車室内への漏水を防止するシール機能とを合わせ持つ。すなわち、本実施形態のクォータウインドウ２０によれば、従来技術（例えば特許文献１）のように、シール部２４を３色成形又は、別部材とすること及び、クォータウインドウ２０をドアフレーム部１２に固定するための固定部材及び固定部の形成が不要となり、部品点数の低減、形状の簡略化が図れる。 Furthermore, since the coating process associated with the hard coat process can be abolished, the seal part 24 is formed after the masking process and the hard coat process which are necessary to ensure the elasticity of the soft resin constituting the seal part 24 of the quarter window 20. Such a process becomes unnecessary. Further, the quarter window panel 21 and the frame portion 22 can be integrally formed of the same resin material having transparency. Further, the seal portion 24 of the quarter window 20 can be integrally formed with the frame portion 22 by two-color molding using a soft resin softer than the synthetic resin constituting the frame portion 22. Moreover, even if the seal part 24 has a configuration in which an undercut part is formed in the die-cutting direction, the seal part 24 and the frame part 22 can be integrally formed by forcibly removing using the elastic force of the soft resin. Therefore, the shape of the seal portion 24 can be press-fitted into the space portion 12c of the door frame portion 12 with a relatively light force, and can be formed into a snap shape that makes it difficult for the seal portion 24 to come off after press-fitting. Therefore, the seal portion 24 has a drop-off preventing function for preventing the quarter window 20 from being detached from the door frame portion 12 and a seal function for preventing water leakage into the vehicle interior by the elastic force of the soft resin constituting the seal portion 24. Have both. That is, according to the quarter window 20 of the present embodiment, as in the prior art (for example, Patent Document 1), the seal portion 24 is molded in three colors or is formed as a separate member, and the quarter window 20 is attached to the door frame portion 12. It is not necessary to form a fixing member and a fixing portion for fixing, and the number of parts can be reduced and the shape can be simplified.
　さらに、クォータウインドウパネル２１とフレーム部２２とが同一の樹脂材料で一体成形される。また、ディビジョンバー部２２ａの先端部２２ｇは、フレーム部２２のうち先端部２２ｇ以外の部分を構成する合成樹脂より軟らかい軟質樹脂で、２色成形により、先端部２２ｇ以外の部分と共に一体成形される。先端部２２ｇは軟質樹脂で構成されるため、先端部２２ｇの形状が内側に湾曲した形状で型抜き方向にアンダーカット部が形成される構成であっても、軟質樹脂の弾性力を利用した無理抜きによる成形が可能である。そのため、ガラスラン２５の外れを防止するための係止部としての先端部２２ｇを成形するための型構造の簡素化が図れる。 Furthermore, the quarter window panel 21 and the frame portion 22 are integrally formed of the same resin material. Further, the distal end portion 22g of the division bar portion 22a is a soft resin softer than the synthetic resin constituting the portion other than the distal end portion 22g in the frame portion 22, and is integrally formed with the portions other than the distal end portion 22g by two-color molding. . Since the tip portion 22g is made of a soft resin, even if the tip portion 22g is curved inward and an undercut portion is formed in the die-cutting direction, it is impossible to use the elastic force of the soft resin. Molding by punching is possible. Therefore, it is possible to simplify the mold structure for forming the tip portion 22g as a locking portion for preventing the glass run 25 from coming off.
　なお、本実施形態では、クォータウインドウ２０は、車両１の後側に位置する後部ドア１０に配置され、ドアガラス１３の後方に位置して、窓部１０ａの後方部分の面積を分割して占めるように取付けられている。しかしながら、例えば、クォータウインドウ２０は、車両１の前側に位置する前側ドア３０に配置され、ドアガラス３３の前方に位置して、窓部３０ａの前方部分の面積を分割して占めるように取付けられるものであってもよい。また、クォータウインドウは、後部ドア１０の後方に位置して、車両１に取り付けられる車両側クォータウインドウ４０に適用してもよい。もちろん、車両側クォータウインドウ４０の位置は、前部ドア３０の前側であってもよい。さらに、上記実施形態では、クォータウインドウパネル２１およびフレーム部２２の両側面（車両側方外側面および車両側方内側面）にハードコートフィルム２３が密着形成されている例について説明したが、ハードコートフィルム２３は、クォータウインドウパネル２１およびフレーム部２２の一方面側（車両側方外側面あるいは車両側方内側面）のみに密着形成されていてもよい。 In addition, in this embodiment, the quarter window 20 is arrange | positioned at the rear door 10 located in the rear side of the vehicle 1, is located behind the door glass 13, and divides and occupies the area of the rear part of the window part 10a. As installed. However, for example, the quarter window 20 is disposed on the front door 30 positioned on the front side of the vehicle 1 and is positioned in front of the door glass 33 so as to divide and occupy the area of the front portion of the window portion 30a. It may be a thing. Further, the quarter window may be applied to the vehicle-side quarter window 40 that is located behind the rear door 10 and attached to the vehicle 1. Of course, the position of the vehicle side quarter window 40 may be the front side of the front door 30. Furthermore, although the said embodiment demonstrated the example in which the hard-coat film 23 was closely_contact | adhered and formed on the both sides | surfaces (vehicle side outer side surface and vehicle side inner side surface) of the quarter window panel 21 and the frame part 22, hard coating was demonstrated. The film 23 may be formed in close contact with only one side of the quarter window panel 21 and the frame portion 22 (the vehicle side outer surface or the vehicle side inner surface).
