Claims

[Scope of utility model registration request]

a base member, a lower link whose one end is rotatably supported by the base member around a horizontal axis and whose other end is supported via a tail link so as to be vertically displaceable; and one end of the lower link. a first slanted link that is rotatably mounted around a horizontal axis and projects diagonally upward; and the first slanted link that is rotatably mounted around a horizontal axis at the other end of the lower link. a second inclined link that similarly projects diagonally upward; an upper link pivotally attached to the upper ends of the first and second inclined links, respectively, so as to be rotatable about a horizontal axis; A lifter driven gear provided on a concentric circle centered on the pivot point between one of the inclined links and the upper link, and a lifter driven gear provided on the upper link and engaged with the lifter driven gear. A matching drive gear for the lifter, a driven sprocket for the tail that rotates around a horizontal axis together with the above-mentioned tail link, a drive sprocket for the tail provided on the above-mentioned upper link, and a gear that is wound around these driven sprockets and the drive sprocket. A seat support device comprising: a wrapped transmission body;
