Claims

[Claims for Utility Model Registration] A base member provided on the floor side, one end of which is rotatably supported by the base member around a horizontal axis, and the other end of which is movable in the vertical direction via a tail support member. a supported lower link; a first diagonal link and a second diagonal link pivotally attached to one end and the other end of the lower link, respectively, so as to be rotatable about a horizontal axis; an upper link that connects the second diagonal link to form a lifter parallel link mechanism; a lifter driven gear provided on a concentric circle centered on a pivot point between the upper link and the diagonal link; a lifter drive gear that is provided on the upper link and meshes with the lifter driven gear; a tail output side gear that is rotatably provided on the lower link; and a tail output side gear that is rotatably provided on the upper link and meshes with the lifter driven gear; Rotational force can be transmitted to the output gear, and the distance between the shafts from the tail output gear is equal to the effective length of the diagonal link, and the gear revolves around the tail output gear in conjunction with the movement of the diagonal link. and a tail driven gear that tilts the lower link by transmitting rotational force input from the tail input gear to the tail output gear to the tail support member. A seat support device featuring:
