Description

【０００１】
【発明の属する技術分野】
本発明は、センターピラーを持たず、フロントドアがその前端部でボディにヒンジ結合され、リヤドアがその後端部でボディにヒンジ結合された又はリヤドアがスライドドアのいわゆる自動車のピラーレス車両において、前記リヤドアの前端部に取付けられるドアウエザーストリップに関するものである。
【０００２】
【従来の技術】
図１乃至図４を参照して説明する。従来、センターピラーを持たず、フロントドア１がその前端部でボディにヒンジ３で結合され、リヤドア２がその後端部でボディにヒンジ３で結合された又はリヤドアがスライドドアのいわゆる自動車のピラーレス車両において、リヤドア２前端部にはリヤドアウエザーストリップ２０が取付けられている。
【０００３】
このリヤドアウエザーストリップ２０は、フロントドアウェザーストリップ９の後端部とボディのルーフ側に取付けたオープニングシール６に弾接して当該部分におけるシール性を確保する。
【０００４】
【発明が解決しようとする課題】
しかし、この従来のリヤドアウエザーストリップ２０は、その上端型成形部１１から侵入した水Ｗが車内４０へ滴下し易いといった問題がある。すなわち、このリヤドアウエザーストリップ２０は、その断面略Ｕ字状の嵌込取付基部１６をドアパネルのフランジ部４に嵌合して取付けるが、上端型成形部１１に頂壁１２および前壁１３ｙを突設しているため、その突出した頂壁１２および前壁１３ｙから嵌込取付部１６とフランジ部４との間に水Ｗが侵入し易く、侵入した水Ｗはそのまま室内４０に滴下してしまう。
【０００５】
本発明はこうした問題に鑑み創案されたもので、ピラーレス車両のリヤドア先端部に取付けたリヤドアウエザーストリップを、その上端型成形部１１の頂壁１２および前壁１３ｙからの水Ｗの侵入を未然に防止できる構造とすることを課題とする。
【０００６】
【課題を解決するための手段】
図１および図５乃至図９を参照して説明する。第一の発明に係るピラーレス車両用ドアウエザーストリップ１０は、ピラーレス車両におけるリヤドア２の前端部に取付けられ、頂壁１２と前壁１３ｙと側壁１３ｚを備えた上端型成形部１１を有し、断面略Ｕ字状の嵌込取付部１６をリヤドアのフランジ部４に嵌合するドアウエザーストリップであり、前記上端型成形部１１の嵌込取付部１６の車内側４０に当たる側壁１３ｚの嵌込面１３ｆの頂壁１２よりやや下位部分に、フランジ部４の車内側４０に接し、後方へ下降傾斜させた堰片１７を前後方向に横設し、側壁１３ｚの後面１３ｇから車内側の表面１３ｈに亘って堰片１７に連続する水受け１８を設け，側壁１３ｚの車内側の表面１３ｈに，水受けと中空シール部の空間部１５とを連通する水抜き孔１９を設けてなるものである。
【０００７】
第二の発明に係るピラーレス車両用ドアウエザーストリップ１０は、ピラーレス車両におけるリヤドア２の前端部に取付けられ、頂壁１２と前壁１３ｙと側壁１３ｚを備えた上端型成形部１１を有し、中空シール部１４と一体成形された断面略Ｕ字状の嵌込取付部１６をリヤドアのフランジ部４に嵌合するドアウエザーストリップであり、前記上端型成形部１１の嵌込取付部１６の車内側４０に当たる側壁１３ｚの嵌込面１３ｆの頂壁１２よりやや下位部分に、フランジ部４の車内４０側に接する堰片１７を前後方向に横設し、側壁１３ｚの後面１３ｇから車内側４０の表面１３ｈに亘って堰片１７に連続する水受け１８を設け，側壁１３ｚの車内側の表面１３ｈに，水受けと中空シール部の空間部１５とを連通する水抜き孔１９を設けてなるものである。さらに、前記堰片１７を、水受け１８に向けて後方へ下降傾斜させてなるものである。
【０００８】
【発明の実施の形態】
本発明に係るピラーレス車両用ドアウエザーストリップ１０の実施形態を、図１および図５乃至図９に示す。７はボディ、８はボディ側面のドア取付用開口部である。リヤドアウエザーストリップ１０は、センターピラーを持たず、フロントドア１がその前端部でボディにヒンジ３で結合されると共に、リヤドア２がその後端部でボディにヒンジ３で結合された又はリヤドアがスライドドアの自動車のいわゆるピラーレス車両における前記リヤドア２の前端部に取付けられる。
【０００９】
また、このドアウエザーストリップ１０は、頂壁１２と前壁１３ｙと側壁１３ｚを備えた上端型成形部１１を有し、中空シール部１４と一体成形された断面略Ｕ字状の嵌込取付部１６をリヤドアのフランジ部４に嵌合して、当該リヤドアに組付けるものである。リヤドアウェザーストリップ１０の上下両端を除く部位の中空シール部１４は、嵌込取付部１６の車外側の部位に車外に向かって突出して設けられ、閉じたフロントドア１の内面が接触するようになっているが、リヤドアウェザーストリップの上部では、嵌込取付部１６に対して中空シール部１４が螺旋状に前方に上昇すると共に前向きに尖った状態に形状を変えて嵌込取付部１６の前側に位置している（図６参照）。Ｊはフロントドアの後端面に対向する面、Ｋはフロントドアウェザーストリップの車内側の面に接離する面、Ｌはボディのルーフサイドに取付けたオープニングシールに接離する面、Ｍはリヤドアの前端面に接触する面、Ｎはリヤドアフランジの車内側の面に接触する面である。そして、上端型成形部１１の嵌込取付部１６の車内側に当たる側壁１３ｚの嵌込側壁１３ｚの後面１３ｇから車内側の表面１３ｈに亘って嵌込面１３ｆの頂壁１２よりやや下位部分に、後が低い堰片１７を前後方向に突設している。また、堰片１７に連続する水受け１８を設け、側壁１３ｚの車内側の表面１３ｚに，水受け１８と中空シール部１４の空間部１５とを連通する水抜き孔１９を設けている。またさらに、堰片１７を水受け１８に向けて下降傾斜させている。
【００１０】
このピラーレス車両用ドアウエザーストリップ１０の作用について説明する。洗車水や雨水等の水Ｗが頂壁１２の下側や前壁１３ｙの後側嵌込取付部１６とフランジ部４との間に侵入した場合、その水Ｗは、堰片１７によって堰き止められる。堰き止められた水Ｗは、側壁１３ｚに添って移動し水受け１８に流され、その水受け１８に設けた水抜き孔１９を通って中空シール部１４の空間部１５に導かれる。この空間部１５はその上端から下端まで連続し、かつ下端は車外に通しているので、当該空間部１５に導かれた水Ｗはそのまま落下し、車外へ排出される。従って、車内へ滴下することがない。
【００１１】
なお、本実施形態においては、堰片１７を、水受け１８に向けて下降傾斜させているので、堰片１７で堰き止められた水Ｗは円滑に水受け１８に案内される。従って、頂壁１２等から嵌込部１６とフランジ部４との間に侵入した水を、さらに円滑に車外３０へ排出することができる。
【００１２】
【発明の効果】
第一の発明（請求項１に記載の発明）は、上端型成形部１１の嵌込取付部１６内面の頂壁１２よりやや下位部分に、フランジ部４の車外側に接する堰片１７を横設し、その嵌込取付部１６外面の車内側４０に、堰片１７に連続する水受け１８を設け、さらに、その水受け１８と中空シール部１４の空間部１５とを連通する水抜き孔１９を設けたので、頂壁１２や前壁１３ｙから嵌込取付部１６とフランジ部４との間に侵入した水Ｗを円滑に車外に排出することができる。これにより、当該水Ｗが車内へ滴下するのを未然に防止することができる。
【００１３】
また、第二の発明（請求項２に記載の発明）は、堰片１７を、水受け１８に向けて下降傾斜させているので、頂壁１２や前壁１３ｙから嵌込取付部１６とフランジ部４との間に侵入した水Ｗを、さらに円滑に車外へ排出することができる。従って、車内への滴下を、より効果的に防止することができる。
