        "excerpt": "Bell Bullitt レトロなオープンフェイスヘルメット。 Bullitt は、Bell により高剛性 ジェットヘルメット 保護システムとして設計され、グラスファイバー複合シェル 製の構造シェルを採用しています。この先進的な積層構造は、衝撃減速時に運動エネルギーを段階的に分散・吸収し、外層ラミネート全体に応力を分散させることで、多密度内部EPSライナーへの局所的な変形伝達を最小限に抑えます。 ECE 22.06 規格に適合し、厳格な線形減速度基準および斜め衝撃試験をクリアすることで、回転加速度による脳損傷リスクを低減する構造となっています。衝撃吸収性能やアンビル試験の詳細については、当社の ECE 22.06 vs DOT vs SNELL ヘルメット安全規格比較ガイド をご覧ください。 内装エルゴノミクスは インターミディエイト・オーバル（中間楕円型） 頭骨プロファイルに沿って成形されており、頭頂部および側頭部への過度な圧迫点を防ぎつつ、頬骨弓に沿った均一なホールド感を提供します。最適な装着安定性と馴染ませ方については、頭部形状プロファイルと頭骨フィッティングガイド および チークパッドの密度と馴染ませプロトコル をご確認ください。 走行時のキャビン静粛性と整流性能は、時速100kmにおいて約 92 dB を記録。内部EPSのベンチレーションダクトと層流エアロダイナミクスにより風切り音を抑制しています。熱疲労や紫外線に対するシェル素材の耐久性については、カーボン vs グラスファイバー vs ポリカーボネート複合シェル比較 で詳しく解説しています。 車両との親和性・推奨ライディングスタイル： 安定したダウンフォースと額部吸気口を備え、ワインディングから高速ツーリングまで幅広いライディングに対応します。総重量 1109 g のバランス設計により重心位置が最適化され、長時間の巡航時でも頸椎への負担を大幅に軽減します。車種ごとのウインドスクリーン適合については、当社の モーターサイクル適合モデル一覧 をご参照ください。",
