To provide a vibration suppression mechanism of an automobile seat which can reduce vibration applied on the automobile seat from a floor by a simple structure, and can suppress the movement of the automobile seat when a large load is applied thereto.SOLUTION: A vibration suppression mechanism 50 is arranged between a cushion frame and an automobile floor. The vibration suppression mechanism 50 is formed while being arranged via a rubber member 53 between a large-diameter substantially-cylindrical outer pipe material 51 and a small-diameter substantially-cylindrical inner pipe material 52 coaxially therewith. In the inner pipe material 52, large-diameter parts 52a are formed at both ends, and a small-diameter part 52b is formed at a center part. The outer pipe material 51 is connected to a side frame 11, and the inner pipe material 52 is connected to the floor. When a large load in a radial direction is applied to the vibration suppression mechanism 50, the large-diameter parts 52a abut on the outer pipe material 51, and an approach of the outer pipe material 51 and the inner pipe material 52 exceeding a prescribed value is suppressed.SELECTED DRAWING: Figure 4
【課題】簡潔な構造でフロアから乗物用シートに印加される振動を低減するとともに大荷重が印加されたときの乗物用シートの移動を抑制可能な乗物用シートの振動抑制機構を提供する。【解決手段】クッションフレームと乗物フロアとの間に配置された振動抑制機構50である。振動抑制機構50は、大径の略円筒状の外パイプ材51と小径の略円筒状の内パイプ材52とが間にゴム部材53を介して同軸状に配置されて形成されている。内パイプ材52は、両端部に大径部52aが中央部に小径部52bが形成されている。外パイプ材51はサイドフレーム11に連結され、内パイプ材52は、フロアに連結されている。振動抑制機構50に径方向の大荷重が印加されたとき大径部52aが外パイプ材51に当接して外パイプ材51と内パイプ材52との所定値以上の接近を抑制する。【選択図】図4
