Abstract (en)
[origin: WO2020003187A1] The invention is a chair structure comprising a supporting frame (2), a flexible member (5), a movable member (15); the supporting frame (2) comprises at least one rigid member (3); the flexible member (5) can be anchored to said frame (2) in proximity to said at least one rigid member (3) and has at least one first end (7) suited to be anchored to the frame (2) and a second end (8) designed to support the lumbar area of the user's back; the movable member (15) is slidably mounted on the flexible member (5) and/or on said at least one rigid member (3) in order to promote a selective variation of the mechanical stiffness provided by the flexible member (5) for the user's back. The movable member (15) can be directly seized by the user in order to promote its selective sliding movement on the flexible member (5) and/or on said at least one rigid member (3); the movable member (15) has a first outer surface (17) designed to directly contact the outer surface (14) of the flexible member (5) and a second outer surface (18) designed to directly contact the outer surface (19) of the rigid member (3).
