A shock absorption unit (10, 20, 100, 200) for absorbing shock has a compressible spring (12, 22, 120, 220) and a securing member (14, 24, 152, 230) for securing the spring. When the magnitude of the shock applied to the shock absorption unit (10, 20, 100, 200) is greater than a prescribed threshold value, the securing member (14, 24, 152, 230) fractures, whereby the shock applied to the shock absorption unit (10, 20, 100, 200) is absorbed. L'invention concerne une unité d'absorption de chocs (10, 20, 100, 200) permettant d'absorber des chocs comprenant un ressort compressible (12, 22, 120, 220) et un élément de fixation (14, 24, 152, 230) pour fixer le ressort. Lorsque l'amplitude du choc appliqué à l'unité d'absorption de chocs (10, 20, 100, 200) est supérieure à une valeur seuil prescrite, l'élément de fixation (14, 24, 152, 230) se rompt, de sorte que le choc appliqué à l'unité d'absorption de chocs (10, 20, 100, 200) est absorbé. 衝撃を吸収するための衝撃吸収ユニット（１０、２０、１００、２００）は、伸縮可能なバネ（１２、２２、１２０、２２０）と、バネを固定するための固定部材（１４、２４、１５２、２３０）とを有している。そして、衝撃吸収ユニット（１０、２０、１００、２００）に加えられた衝撃の大きさが所定の閾値よりも大きいときに固定部材（１４、２４、１５２、２３０）が破断することにより、衝撃吸収ユニット（１０、２０、１００、２００）に加えられた衝撃を吸収する。
