Description
a=(Vi−Vo)/t ここでaは加速度
Viは初期速度、例えばその衝突が起こる時の速度、
Voは最終速度で、ここではゼロであり、tはViがゼロに減少する時間である。
従って、衝撃時間が短ければ短いほど、頭部が受ける加速度は大きくなり、従って、以下の式によれば、頭部に作用する力は大きくなる。
F=m・a
例えば
F=m・aVi)/t ここでmはユーザの頭部の質量である。
図9−bは、前記シェルの側方に位置し、前記機構の駆動ボタン35の一つを図示する前記CPCの一部外側図であり、シェルの反対側には類似の対称配置されたボタンが設けられている。
−顔面保護構造、これは前方衝撃に対して保護する、
−トルクとびまん性軸索損傷(DAI)のリスクの低減、
−約1kgである低減された重量、さらに、快適性の増大と空気力抵抗の減少、
−バイザ取り付けシステム、光学的効率の増大と取り外し可能なチンガード、
−乳様突起領域の吸収材、
−ユーザ頭部のより良好なCPCの保持、
−突起の無いスムースなシェル、外部障害物に対する頭部ロックを回避、これはトルクの低減又は防止に寄与する。
Claims (13)
