【発明の属する技術分野】
本発明は、車室の上部を開閉自在に覆う幌と、車室の後部に固定されたロールバーとを備えたカブリオレ車に関し、特にその車体補強構造に関する。
【０００２】
【従来の技術】
従来のカブリオレ車は、車室の上部を開閉自在に覆う幌のリンクフレームを支持する幌支持用ブラケットが車体内側のパネルに固定されていた。また特開平７−２７７１１８号公報には、ロールバーを備えたカブリオレ車において、幌のリンクフレームを支持する幌支持用ブラケットを前記ロールバーに固定したものが開示されている。
【０００３】
【発明が解決しようとする課題】
固定ルーフを備えていないカブリオレ車は固定ルーフを備えた通常のセダン等に比べて車体剛性が低下しがちであり、充分な車体剛性を確保すべく補強を施すと車体重量が増加してしまう問題がある。また上述したように、幌支持用ブラケットを車体のパネルやロールバーに単純に固定しても、その幌支持用ブラケットを車体剛性の増加に寄与させることができないという問題がある。
【０００４】
本発明は前述の事情に鑑みてなされたもので、カブリオレ車の幌支持用ブラケットを利用して車体重量を増加させることなく車体剛性を増加させることを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明は、車室の上部を開閉自在に覆う幌と、車室の後部に固定された不動のロールバーとを備えたカブリオレ車において、前記幌のリンクフレームを折り畳み可能に支持する左右一対の幌支持用ブラケットを、前記ロールバーとは別個にボディに固定し、その左右一対の前記幌支持用ブラケットに、車体左右方向に延びる連結補強部材の左右両端をそれぞれ固定すると共にその連結補強部材の左右中間部に前記ロールバーを固定して、該連結補強部材及び左右一対の幌支持用ブラケットを介して前記ロールバーとボディとが相互に接続されるようにしたことを特徴とする。
【０００６】
上記特徴によれば、高剛性の部材であって車室の後部に固定された不動のロールバーと、ボディとが、ロールバーとは別個にボディに固定した左右一対の幌支持用ブラケット、並びにその両ブラケットに左右両端を固定し且つロールバーに左右中間を固定した連結補強部材を介して相互に接続されるので、既存の幌支持用ブラケットを利用して車体剛性を効果的に増加させることができる。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態を、添付図面に示した本発明の実施例に基づいて説明する。 図１〜図６は本発明の一実施例を示すもので、図１はカブリオレ車の車室を右斜め前方から見た斜視図、図２は図１の要部拡大図、図３はカブリオレ車の幌を左斜め後方から見た斜視図、図４は図３の４方向拡大矢視図、図５は図４の５方向矢視図、図６は幌の折り畳み過程を示す作用説明図である。
【０００８】
図１および図２に示すように、二人乗りのカブリオレ車Ｖの車室１は、その左右両側面がドア２L ，２R で開閉され、その上面が折り畳み自在な幌３で開閉される。車室１の底壁を構成するフロアパネル４の後端から、図示せぬシートのシートバックに沿うように上下壁５が立ち上がり、この上下壁５の上端から水平壁６が車体後部に向けて延びている。金属パイプを逆Ｕ字状に湾曲させた左右一対のロールバー７L ，７R は下端にそれぞれ一対の取付フランジ８，８；９，９を備えており、車体外側の取付フランジ８，８は前記水平壁６の上面に固定されるとともに、車体内側の取付フランジ９，９は車室１の中央部を前後方向に延びるセンタートンネル１０の後部上面に固定される。
【０００９】
ドア２L ，２R の後方に連なる車体のインナーパネル１１，１１に、左右一対の幌支持用ブラケット１２L ，１２R の前部が各々３本のボルト１３…で固定され、更に前記幌支持用ブラケット１２L ，１２R の後部が車体左右方向に延びる連結補強部材１４の左右両端に各々２本のボルト１５，１５で固定される。左右のロールバー７L ，７R の車体内側の取付フランジ９，９の近傍が、前記連結補強部材１４の前面に固定部材１６，１６を介して固定される。つまり、左右の幌支持用ブラケット１２L ，１２R の前部は本発明のボディを構成するインナーパネル１１，１１に接続され、また後部は連結補強部材１４を介してロールバー７L ，７R に接続される。その結果、インナーパネル１１，１１とロールバー７L ，７R とが幌支持用ブラケット１２L ，１２R を介して一体化され、固定ルーフを持たないために低下したカブリオレ車Ｖの車体剛性を、特別の補強部材を設けることなく、幌支持用ブラケット１２L ，１２R を利用して効果的に高めることができる。
【００１０】
次に、図３〜図６を併せて参照しながら幌３の構造を説明する。
【００１１】
カブリオレ車Ｖの車室１の上部を開閉自在に覆う幌３は、その骨格を構成するリンクフレーム２１と、リンクフレーム２１に張設されたシート２２とから構成される。幌３のリンクフレーム２１は左右対称の構造を備えているため、図面に示された左半部の構造を代表として説明する。

【００１３】
第１リンク２３にはドアガラスの後部上縁が当接する第１サイドメンバ２０が固定されるとともに、第３リンク２８にはドアガラスの中央部上縁が当接する第２サイドメンバ２９が固定される。また左右の第１リンク２３，２３に中間部に車体左右方向に延びてシート２２の後部下面を支持する第１クロスメンバ３０の両端がピン３１，３１で枢支されるとともに、左右の第１リンク２３，２３の他端に車体左右方向に延びてシート２２の中央部下面を支持する第２クロスメンバ３２の両端が固定される。
【００１４】
ドアガラスの前部上縁が当接する第３サイドメンバ３３の一端が前記第２サイドメンバ２９の一端にピン３４を介して枢支され、左右の第３サイドメンバ３３，３３の他端間がフロントガラスの上縁に当接可能なフロントクロスメンバ３５により接続される。
【００１５】
第３リンク２８の他端近傍にピン３６を介して一端を枢支された第４リンク３７と、第３サイドメンバ３３の中間部にピン３８を介して一端を枢支された第５リンク３９とが、それらの他端においてピン４０で枢支される。前記ピン４０には第６リンク４１の一端が枢支されており、この第６リンク４１の他端はピン４２を介して第１リンク２３の他端に枢支される。第６リンク４１の一端近傍にピン４３を介して第７リンク４４の一端が枢支されており、左右の第７リンク４４，４４の他端に車体左右方向に延びてシート２２の前部下面を支持する第３クロスメンバ４５の両端が固定される。
【００１６】
幌支持用ブラケット１２L の車体内側面に設けられる駆動ユニット５０はモータ５１および減速機５２を一体に備えており、減速機５２の出力軸に設けたピニオン５３が幌支持用ブラケット１２L の開口１２1 を貫通して車体外側面に突出する。第１リンク２３の一端には中心が支軸１９に一致するようにセクタギア５４が固定されており、このセクタギア５４に駆動ユニット５０のピニオン５３が噛合する。
【００１７】
而して、幌３を閉じて車室１の上部を覆った図４の状態から、駆動ユニット５０のモータ５１を駆動してピニオン５３を回転させると、ピニオン５３に噛合するセクタギヤ５４が駆動されてリンクフレーム２１の第１リンク２３が図４の矢印Ａ方向に回動する。その結果、四節リンク機構の３本のリンクを構成する第１リンク２３、第２リンク２５および第３リンク２８が図６に示すように変形し、第３リンク２８は第１、第２リンク２３，２５に対して相対的に矢印Ｂ方向に回動する。
【００１８】
第３リンク２８の矢印Ｂ方向の回動に伴って、第１リンク２３にピン４２を介して枢支された第６リンク４１が第３リンク２８に対して相対的に矢印Ｃ方向に移動するため、第６リンク４１にピン４０を介して枢支された第４リンク３７および第５リンク３９が矢印Ｃ方向に引かれ、その結果、第３サイドメンバ３３は第２サイドメンバ２９に対して相対的に矢印Ｄ方向に回動する。駆動ユニット５０によって第１リンク２３を更に回動させると、最終的に第１サイドメンバ２０、第２サイドメンバ２９および第３サイドメンバ３３は側面視で概略Ｚ字状に折り畳まれ、幌３は車室１の後部に収納される。
【００１９】
以上、本発明の実施例を詳述したが、本発明はその要旨を逸脱しない範囲で種々の設計変更を行うことが可能である。
【００２０】
例えば、実施例では、幌支持用ブラケット１２L ，１２R をボディ（インナーパネル１１，１１）に直接接続しているが、その代わりに、両者間に他の強度部材を介在させても良い。
【００２１】
【発明の効果】
以上のように本発明によれば、高剛性の部材であって車室の後部に固定された不動のロールバーと、ボディとが、ロールバーとは別個にボディに固定した左右一対の幌支持用ブラケット、並びにその両ブラケットに左右両端を固定し且つロールバーに左右中間を固定した連結補強部材を介して相互に接続されるので、既存の幌支持用ブラケットを利用して車体剛性を効果的に増加させることができる。
