충격 하중이 부하되는 방향이 충격 흡수 방향과 교차하는 방향이어도, 보다 안정적으로 벨로즈 형상의 압궤 변형이 발생하고, 또한 경량의 충격 흡수 부품을 제공한다. 본 발명에 따른 충격 흡수 부품은, 코어층(5)의 양측면에, 금속판으로 이루어지는 표층(3A, 3B)을 접합 적층하여 이루어지는 적층 금속판(1)을 성형한 부재로 구성되어 있다. 충격 흡수 부품을 구성하는 적층 금속판(1)의 중심층의 변형률을 제어함으로써, 충격 하중의 부하 방향에 상관없이, 작은 파장으로 변형되기 때문에, 본 발명의 충격 흡수 부품은, 보다 안정적으로 벨로즈 형상의 압궤 변형이 가능해진다.

    To provide a crash energy absorbing part which is light in weight, and in which collapsing deformation into a bellows shape occurs more stably even when a crash load is applied in a direction crossing the shock-absorbing direction of the crash energy absorbing part. The crash energy absorbing part of the present invention is constructed of a member that is obtained by forming a sandwich metal sheet (1), which is formed by laminating a surface layer (3A, 3B) formed of a metal sheet on each side surface of a core layer (5) and bonding them. By controlling a deformation rate of a center layer of the sandwich metal sheet (1) for constructing the crash energy absorbing part, the crash energy absorbing part of the present invention is deformed at a short wavelength regardless of a direction of a crash load that is applied, whereby collapsing deformation into a bellows shape more stably occurs.
