Description
例えば、特許文献1にはバンパビームとバンパ間に合成樹脂発泡体を介在させることにより、歩行者と搭乗者の安全を両立させる技術が開示されている。
そして、リブは、センタビームの垂直面を覆う表面と水平面を覆う表面を2つの辺とした3角形状に形成され、3角形状の斜辺が、隣り合うアウタビームの3角形状の斜辺と、互いに前記アウタビームの長手方向に沿って交差する形態で設けられるのが好ましい。
図1に示すように、バンパビーム11は複数の垂直面1を一体に連結した断面形状を備えた金属材質のセンタビーム3と、センタビーム3の外側を覆う断面形状を備えたプラスチック材質のアウタビーム5と、アウタビーム5の外側に備えられた複数のリブ7とを含んで構成される。
リブ7は、隣接した2つの辺がアウタビーム5の隣接した2つの表面に連結された3角形状、すなわち、センタビームの垂直面を覆う表面と水平面を覆う表面を2つの辺とした3角形状に形成され、3角形状の斜辺が、隣り合うアウタビームの3角形状の斜辺と、互いにアウタビームの長手方向に沿って交差する形態で設けられている。
バンパビーム11は、センタビーム3とアウタビーム5とで担う全体的な強度が、従来の単純な平板を折り曲げた断面形状を有するバンパビームと概ね同じになるように形成される。
即ち、センタビーム3自体の強度は、従来のバンパビームに比べて多少弱く形成され、弱くなった強度はアウタビーム5が補うようになっている。
勿論、バンパビーム11の強度は、バンパビーム11が装着される車体19の前方部分よりは弱い強度から形成される。
特に、バンパビーム11の変形は、衝撃が加えられた変形初期にはプラスチック材質のアウタビーム5が破損されながら衝撃エネルギーを急速に吸収する作用をし、以後にはセンタビーム3がバンパビーム11の変形時間をできるだけ長く形成するようにする。
この時、アウタビーム5に形成されたリブ7は、センタビーム3を助けてバンパビーム11の変形時間を長くするのに寄与する。
