To provide a seating structure capable of raising a seating support part on which a user sits to a standing position that makes it easier for the user to stand up, and suppressing the user's feeling of fear from being evoked when raising.SOLUTION: A pair of right/left seat frame rods 12 across which a seating seat part 31 spans are divided into a front rod part 41 fixed to a base frame 11, and a rear rod part 42 to be converted into a seating position and a standing position. A position conversion mechanism 51 is configured to hold the rear rod part 42 into a backward tilting attitude or a horizontal attitude in the seating position and the standing position, and to raise and lower it in the seating position and the standing position via an intermediate attitude that is not tilted forward from the horizontal attitude and tilted backward from a seating-position attitude. This configuration allows the user to stably sit on a seat main part 34 that spans across the right/left rear rod parts 42, and can suppress the user's feeling of fear from being evoked when raising and lowering.SELECTED DRAWING: Figure 2
【課題】使用者が着座する着座支持部を、使用者が立上り易くする立上り位置へ昇動させると共に、該昇動させる際に使用者に恐怖感が想起されてしまうことを抑制し得る着座構造物を提案する。【解決手段】着座シート部31が差し渡された左右一対の座フレーム杆部12が、ベースフレーム部11に固結された前側杆部41と、着座位置と立上り位置とに変換される後側杆部42とに分離されてなり、後側杆部42を、位置変換機構51によって、着座位置と立上り位置とで後傾姿勢または水平姿勢に保持すると共に、水平姿勢よりも前傾させず且つ着座位置の姿勢よりも後傾させた中間姿勢を介して、着座位置と立上り位置とに昇降させる構成である。本構成によれば、左右の後側杆部42に差し渡されたシート主部34で、使用者が安定して着座でき、昇降時に恐怖感が想起されることを抑制できる。【選択図】図2
