Abstract
Description
図1にはインパネリインフォースメントの組付状態の斜視図が示されており、又図2には当該インパネリインフォースメントの縦断面図が示されている。これらの図に示されるように、インパネリインフォースメント10は、対角線にて二分割された四角形断面のプレス構造体12として構成されている。なお、このプレス構造体12が本発明における「インパネリインフォースメント本体」に相当する。具体的には、プレス構造体12は、各々プレス成形によって構成されると共に断面形状がL字状となるように形成された一方の部材としてのアッパ部材14と他方の部材としてのロア部材16の二部品で構成されている。
図1に戻り、上記プレス構造体12の長手方向の両端部には、平面視でL字状に形成された取付ブラケット30がそれぞれ取り付けられている。各取付ブラケット30は、プレス成形によって製作されている。また、取付ブラケット30は、プレス構造体12の長手方向の端部に形成された四角形断面を塞ぐベース部32と、このベース部32の後端部を車両幅方向外側へ折り曲げることにより形成された取付部34と、を備えている。これらの取付部34が左右一対のフロントピラー43の後壁部にそれぞれ締結固定されるようになっている。これにより、インパネリインフォースメント10が左右のフロントピラー43間に架け渡されている。
また、インパネリインフォースメント10の運転席側には、ステアリングサポートブラケット52及びカウルトゥブレース54が取り付けられている。ステアリングサポートブラケット52は、ロア側のみで構成されている。つまり、ステアリングサポートブラケット52のアッパ側は廃止されている。具体的には、ステアリングサポートブラケット52は、プレス構造体12のアッパ部材14側に固定される第1サポート部材56と、プレス構造体12のロア部材16側に固定される第2サポート部材58と、によって構成されている。第1サポート部材56及び第2サポート部材58は、いずれもプレス成形によって製作されている。
また、上述したステアリングサポートブラケット52の第1サポート部材56には、当該第1サポート部材56を車両幅方向に挟むように各々ブレース部材としてのフロアブレース84及びステアリングブレース86が取り付けられている。
図7には、センター断面での収まりが概略的に示されている。この図に示されるように、センター断面では、インパネリインフォースメント10の車両前方側にHVAC(heating and ventilating air conditioning)130が配設されている。HVAC130の上部の中央側にはデフロスタ132の下端部が接続されている。また、デフロスタ132の車両後方側には、センターメータ134が配設されている。さらに、HVAC130の上部の後端側には、センターダクト136の前端部136Aが接続されている。センターダクト136の中間部136Bは、センターメータ134と干渉しないようにインストルメントパネル138の上面部138Aの下側を車両前後方向に沿って延設されている。さらに、センターダクト136の後端部136Cは、インストルメントパネル138に設けられた吹出し口140に接続されている。
また、図9に示されるように、ステアリングコラム78はその軸線Qの傾斜角度θが20°~22°となるように設定されている。本態様では、インパネリインフォースメント10の上面部18がステアリングコラム78の軸線Qに対して略平行になるようにインパネリインフォースメント10の軸線回りの向きが設定されている。なお、図9において、インパネリインフォースメント10を跨ぐように配設されている部材は、概略的に図示したステアリングサポート部材154である。
次に、本態様の作用並びに効果について説明する。
(1)上述した態様では、長手方向に対して直交する方向に切断したときの断面形状がL字状とされたアッパ部材14を四角形断面の上部に配置し、同断面形状が略L字状とされたロア部材16を四角形断面の下部に配置したインパネリインフォースメント10としたが、これに限らず、メリットは減るが、他の断面構造を採用してもよい。例えば、アッパ部材14とロア部材16の前後の配置関係を逆にしてもよい。また、例えば、アッパ部材の断面形状を下方が開放されたU字状に形成し、当該アッパ部材の開放側端部を平板状のロア部材で閉止するような断面形状(対角線で二分割されていない四角形断面形状)にしてもよい。
(2)上述した態様では、多数点同時にプロジェクション溶接したが、必ずしも同時である必要はなく、例えば、運転席側のプロジェクション溶接を先に行ってから助手席側のプロジェクション溶接を行うようにしてもよい。
(3)請求の範囲における「平行」なる記載は、比較する二者が完全に平行になっている場合の他、比較する二者が完全に平行にはなっていないが本発明の効果が実質的に得られる場合も含む。
