本発明は、自動車のベルトラインより上方において、車外側に装飾部材が設けられたリヤドアに取付けられ、フロントドアとの間をシールするウェザーストリップの取付構造に関するものである。   The present invention relates to a weather strip mounting structure that is mounted on a rear door provided with a decorative member on the outside of a vehicle and that seals the front door above the belt line of the vehicle.

自動車のベルトラインより上方におけるフロントドアとリヤドアとの間には、両ドア間のシール性を確保するためにウェザーストリップが取付けられ、また、両ドアの車外側に、高級感を現出するためにガーニッシュ,モール,カバーといった装飾部材が取付けられたものが開示されている(例えば、特許文献1および2参照)。
特開2003−291653号公報 特開2005−47447号公報
A weather strip is installed between the front door and the rear door above the belt line of the car to ensure the seal between the two doors, and a high-grade appearance is exhibited on the outside of the car on both doors. Are provided with decorative members such as garnishes, moldings, and covers (see, for example, Patent Documents 1 and 2).
JP 2003-291653 A JP 2005-47447 A

しかし、特許文献1に記載のウェザーストリップ(シール材)は、当該ウェザーストリップに取付孔を設け、その取付孔にウインドウガラスに嵌着したモールから立設した突起を挿入し、当該突起を加熱・加圧変形する、いわゆる熱カシメによって取付けるので、取付作業が面倒であるといった問題がある。   However, in the weather strip (sealing material) described in Patent Document 1, a mounting hole is provided in the weather strip, and a protrusion erected from a molding fitted to the window glass is inserted into the mounting hole. Since mounting is performed by so-called thermal caulking that is deformed under pressure, there is a problem that the mounting operation is troublesome.

また、特許文献2に記載のウェザーストリップ(パーティングシール)は、その取付基部をサッシュカバーのフランジに係合して取付けるものであり、当該サッシュカバーは樹脂製であり剛性が必ずしも充分ではないので、組付き力が不十分であるといった問題がある。   In addition, the weather strip (parting seal) described in Patent Document 2 is attached by engaging its mounting base with the flange of the sash cover, and the sash cover is made of resin and does not necessarily have sufficient rigidity. There is a problem that the assembling force is insufficient.

これらの点に鑑み、図5および図6に示すように、リヤドア2の前端部に形成したフランジ3に、断面略U字状の取付基部31とシール部32を一体成形したウェザーストリップ30を取付け、シール部32をフロントドア5の後端部に弾接させて両ドア2,5間をシールするものが創案されている。
また、この取付基部31の内面には、フランジ3に弾接してフランジ3に保持される複数の係止リップ33と小突起34が設けられている。また、フランジ3に対する組付き力を強固なものとするために取付基部31には芯金35を埋設している。
In view of these points, as shown in FIGS. 5 and 6, a weather strip 30 in which a mounting base portion 31 having a substantially U-shaped cross section and a seal portion 32 are integrally formed is attached to the flange 3 formed at the front end portion of the rear door 2. The seal portion 32 is elastically brought into contact with the rear end portion of the front door 5 to seal between the doors 2 and 5.
A plurality of locking lips 33 and small protrusions 34 are provided on the inner surface of the mounting base 31 so as to be elastically contacted with the flange 3 and held by the flange 3. Further, a core bar 35 is embedded in the mounting base 31 in order to strengthen the assembling force with respect to the flange 3.

しかしながら、上記のウェザーストリップ30は、その取付基部31をフランジ3に強固に取付けるために芯金35を埋設する必要があるので、重量が嵩み、近年推進されている自動車の軽量化傾向にそぐわないといった問題がある。   However, since the weather strip 30 needs to embed the cored bar 35 in order to firmly attach the attachment base 31 to the flange 3, the weight strip 30 is heavy and does not match the trend of weight reduction of automobiles promoted in recent years. There is a problem.

こうした点を踏まえ、取付基部31に芯金35を埋設しないことも考えられるが、そうするとフランジ3に対する組付き力が低下してしまうので好ましくない。   In consideration of these points, it is conceivable not to embed the cored bar 35 in the mounting base 31, but this is not preferable because the assembly force to the flange 3 is reduced.

そこで、本発明の目的とするところは、自動車のベルトラインより上方において、車外側に装飾部材が設けられたリヤドアに取付けられ、フロントドアとの間をシールするウェザーストリップの取付構造において、取付けが容易で、強固に取付けることができ、かつ芯金の埋設を不要として軽量化を図ることのできる製品を提供することにある。   Accordingly, an object of the present invention is to provide a weather strip mounting structure that is attached to a rear door provided with a decorative member on the outside of the vehicle above the belt line of the automobile and seals between the front door.
