PROBLEM TO BE SOLVED: To provide a seat support mechanism in which an operation for converting the orientation of a seat can be performed easily only by a series of operations with a simple structure, and which achieves a design for restraining the rotation and advancing/retreating of the seat simultaneously.SOLUTION: A seat support mechanism includes: a leg base 11 firmly provided on a floor surface by a side wall A; a movable table 20 arranged on the lower side of an upper surface part 12 of the leg base 11, and capable of advancing/retreating in the direction orthogonal to the side wall A; an underframe 30 of the seat arranged on the upper side of the upper surface part 12 of the leg base 11, and supported by the movable table 20 rotatably by a rotary shaft 41 for avoiding interference with the upper surface part 12; and an interlock mechanism 50 for interlocking the rotation of the underframe 30 and the advancing/retreating. The interlock mechanism 50 converts the rotation of the underframe 30 into a linear motion and transmits it to the movable table 20 via the rotary shaft 41 when the seat is rotated together with the underframe 30, and advances/retreats the movable table 20 in the direction orthogonal to the side wall A with the underframe 30.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、しかも、座席の回転と進退を同時に拘束することができる設計を可能とする座席支持機構を提供する。【解決手段】側壁Aの傍らで床面上に固設された脚台11と、脚台11の上面部12の下側に配置され、側壁Aと直交する方向へ進退可能な移動台20と、脚台11の上面部12の上側に配置され、該上面部12との干渉を回避する回転軸41により移動台20に回転可能に支持された座席の台枠30と、台枠30の回転と進退を連動させる連動機構50を備える。連動機構50は、座席を台枠30と共に回転させた時、該台枠30の回転を直線運動に変換し回転軸41を介して移動台20に伝達し、移動台20を台枠30と共に側壁Aと直交する方向へ進退させる。【選択図】図1
