To provide a low-cost retractable audience seating in a simple structure.SOLUTION: A retractable audience seating 1 is provided with a plurality of seats 10, a floor base 20 with a plurality of steps on which the seats 10 are secured, and a back actuating mechanism 30. The seat 10 comprises a back 11 and a base 12. The back actuating mechanism 30 is provided with: a pair of back actuating parts 31 secured on an inner surface of the back 11; a main axis 32 supporting rotation of the back actuating parts 31 and functioning as a rotational supporting point; a pair of back rotating members 33 rotating the back actuating parts 31; a main rotating member 34 rotating the back rotating members 33; a shaft 35 rotating the main rotating member 34; an actuator 40 actuating the shaft 35; and a supporting member 50 supporting the back rotating members 33 from a lower side. The back actuating mechanism 30 allows the back 11 to move between a use position and a retractable position and the floor base 20 is secured by support of a second end part 33b of the back rotating member 33 of the back actuating mechanism 30 and the supporting member 50.SELECTED DRAWING: Figure 4
【課題】構成が簡単で低コストな収納観覧席を提供する。【解決手段】収納式観覧席１は、複数の椅子１０と、椅子１０を固定する複数段の床台２０と、背駆動機構３０とを備える。椅子１０は、背１１と座１２とを有している。背駆動機構３０は、背１１の内面に固定される一対の背駆動部３１と、背駆動部３１の回動を支え回動支点となる主軸３２と、背駆動部３１を回動させる一対の背回動部材３３と、背回動部材３３を回動させる主回転部材３４と、主回転部材３４を回動させるシャフト３５と、シャフト３５を駆動させるアクチュエータ４０と、背回動部材３３を下方から支持する支持部材５０とを備える。背駆動機構３０による背１１の使用位置と収納位置との移動を可能とし、背駆動機構３０の背回動部材３３の第２端部３３ｂと支持部材５０との支持により床台２０が安定する。【選択図】図４
