Disclosed is seated person can easily stand, to provide an auxiliary function with the seating device that can change the orientation. And a base 20 and a drive mechanism [SOLUTION] standing assistance mechanism, under the 10 seat units standing assist mechanism, is provided on the back side of the upright auxiliary mechanism driving mechanism, the drive mechanism comprises a movable body, standing aid and a number of links present, some of the links are connected to the seat unit 10, other links are connected to the base 20, other links are connected to the moving body, the seat unit 10 of the mobile mechanism was to be raised and lowered to match the lift. Rotating body does not rotate and a base 20 and orientation changing mechanism, the rotating body reorientation mechanism, connected to the seat unit 10 and the rotating body, and is grounded to the installation surface of the base 20, from the installation surface of the base 20 was to rotate the rotating body is grounded to the mounting surface and the float. Seating device may also be equipped with both the direction changing mechanism and standing auxiliary mechanism. [Selection] Figure Figure 1【課題】着座者が容易に起立でき、向きを変えることができる補助機能付き着座具を提供する。【解決手段】起立補助機構と駆動機構とベース20を備え、起立補助機構を座部ユニット10の下に、駆動機構を起立補助機構の背面側に設け、駆動機構は移動体を備え、起立補助機構は数本のリンクを備え、一部のリンクが座部ユニット10に連結され、他のリンクがベース20に連結され、他のリンクが移動体に連結され、座部ユニット10が移動体の昇降に合わせて昇降するようにした。向き変更機構とベース20を備え、向き変更機構を回転体とし、回転体を座部ユニット10に連結し、ベース20を設置面に接地させると回転体が回転せず、ベース20を設置面から浮かすと回転体が設置面に接地して回転するようにした。着座具は起立補助機構と向き変更機構の双方を備えたものでもよい。【選択図】図1
