PROBLEM TO BE SOLVED: To provide a seat support mechanism that enables the operation of changing a seat direction to be easily carried out only through a series of operations with a simple structure, overall seat cost to be reduced, and a sufficient space to be secured in the leg base of the seat.SOLUTION: A leg base 11 is fixed beside a side wall A, a movable carriage 21 is provided to the upper surface 12 side of the leg base 11 so as to be movable in a direction orthogonal to the side wall A, and the pedestal 31 of a seat 1 is rotatably supported on the upper surface side of the movable carriage 21. The seat 1 itself and a part of the outer periphery of the pedestal 31 becomes cam part that is displaced in contact with the side wall A. When the seat 1 is rotated, the pedestal 31 is pushed in a direction away from the side wall A by the seat 1 itself or the cam part of the pedestal 31, by the pushing force, the movable carriage 21 is moved in the direction away from the side wall A against an urging force, and the displacement locus of the cam part is secured along the side wall A.SELECTED DRAWING: Figure 1
【課題】座席の向きを変換する動作を、簡易な構成による一連の操作だけで容易に行うことができ、座席全体のコスト低減が可能となり、座席の脚台内には充分なスペースを確保できる座席支持機構を提供する。【解決手段】脚台11が側壁Aの傍らに固設され、脚台11の上面12側に移動台21が側壁Aと直交方向に移動可能に設けられ、該移動台21の上面側に座席1の台座31が回転可能に支持される。座席1自体または台座31の外周の一部が側壁Aに対接しながら変位するカム部となる。座席1を回転させると、座席1自体または台座31のカム部によって台座31は側壁Aから離れる方向に押圧され、該押圧力によって、移動台21が付勢力に抗して側壁Aから離れる方向に移動し、カム部の変位軌跡が側壁Aに沿って確保される。【選択図】図1
