To provide a seat support device which can make sure that rotation and slide of a seat are linked with simple configuration.SOLUTION: A seat support device comprises: a rotating mechanism 40 which rotates a seat 1 around a rotary shaft 41; a slide mechanism 15 which slides the seat 1 together with the rotating mechanism 40 from a leg base 11; and a link mechanism 50 which links slide operation with rotation operation of the seat 1. The link mechanism 50 comprises plural link members 51, 52 which are connected to each other between the leg base 11 and a movable carriage 20. Any one link member 52 oscillates in association with rotation operation of the seat 1 to bend or extend each line member 51, 52, and links slide operation of the seat 1.SELECTED DRAWING: Figure 1
【課題】簡易な構成により座席の回転とスライドを確実に連動させることができる座席支持装置を提供する。【解決手段】座席1を回転軸41周りに回転させる回転機構40と、座席1を脚台11より回転機構40ごとスライドさせるスライド機構15と、座席1の回転動作にスライド動作を連動させるリンク機構50と、を備える。リンク機構50は、脚台11と移動台20との間で互いに連結された複数のリンク部材51,52を備え、何れか一つのリンク部材52は、座席1の回転動作に伴ない揺動して各リンク部材51,52を屈曲ないし伸展させ、座席1のスライド動作を連動させる。【選択図】図1
