An impact absorbing device for a vehicle seat includes: a first base member; a second base member; and an impact absorbing member. The first base member rotatably supports the second base member. Theimpact absorbing member includes: a first fixing portion fixed to the first base member; a second fixing portion fixed to the second base member; and a deformable portion. The deformable portion is provided between the first fixing portion and the second fixing portion, and is configured to be bent by the rotation of the second base member. A distance between the first fixing portion and the second fixing portion (51) in an undeformed state of the deformable portion has a value intermediate in a range of variation of the distance that varies depending on the bending of the deformable portion.
交通工具用座椅的冲击吸收装置具有:第1基座部件、第2基座部件和冲击吸收部件。第1基座部件将第2基座部件支承为能够进行旋转。冲击吸收部件具有:被固定在第1基座部件的第1固定部;被固定在第2基座部件的第2固定部;和变形部。变形部被设置在第1固定部与第2固定部之间,会因第2基座部件(51)的旋转而弯曲。变形部弯曲前的第1固定部与第2固定部之间的距离是距离的变化范围的中间值。
