To provide a seat pad of which a resonant frequency can be changed without changing a foam itself which constitutes a seat pad, a vehicle seat, and a vehicle seat controlling method.SOLUTION: The seat pad has a foam, and a bag body having air permeability which covers the foam. The seat pad comprises a packaging pad part. A time T1, which is required from a time point when compression of the packaging pad part in a prescribed compression state is released to a time point when the packaging pad part is restored to a state before compression, is longer than a time T0 which is required from a time point when compression of the foam in a prescribed compression state is released in the case that the foam is not covered at all to a time point when the foam is restored to a state before compression.SELECTED DRAWING: Figure 2
【課題】シートパッドを構成する発泡体自体を変えることなく、シートパッドの共振周波数を変化させることが可能な、シートパッド、車両用シート、及び、車両用シートの制御方法を、提供する。【解決手段】本発明に係るシートパッドは、発泡体と発泡体を覆った通気性のある袋体とを有する、包装パッド部を備え、発泡体が何も覆われていない場合に発泡体が所定の圧縮状態で圧縮が解除されてから圧縮前の状態へ復元するまでにかかる時間T0よりも、包装パッド部が所定の圧縮状態で圧縮が解除されてから圧縮前の状態へ復元するまでにかかる時間T1のほうが、長い。【選択図】図2
