<p>A swing stowed-type chair includes: a base portion 1 to be fixed to a floor or a desk; a sitting portion 2 with a back 2a and a scat 2b, which are united to each other; a front-side leg portion 4, whose lower end portion and upper end portion are connected to the base portion and the sitting portion, respectively, swingably in a forward/rearward direction; a rear-side leg portion 7, whose lower end portion and upper end portion are connected to the base portion and the sitting portion, respectively, swingably in the forward/rearward direction, where swing axes of the upper and lower end portions are located more rearward than swing axes of the upper and lower end portions of the front-side leg portion; and a stopper assembly 11 for limiting, in a predetermined range, the swing of the front-side and rear-side leg portions relative to the base portion and the sitting portion. The front-side and rear-side leg portions form a non-parallel four-joint link, in order that, in a rearward-swing limit position, the sitting portion is placed so that the seat and the back are in a use position, while, in a forward-swing limit position, the sitting portion is placed so that the seat and the back are in a forward slanted position. By coming into contact with a shaft 10, the stopper assembly 11 provides the limit of the rearward-swing limit position of the front-side and rear-side leg portions according to the state where the base portion is slanted downward toward the front. Thus, even when the chair is installed in a place slanted downward toward the front, the sitting portion can be set to the use position in the rearward-swing limit position.</p> |
