Abstract
The improvements are applicable to devices that form part of structures in which the chair and backrest are assembled as independent elements. Based on the improvements, it is possible to simultaneously adjust the rake of the backrest and of the actual seat in synchronization, independently of the conventional heightwise adjustment of the latter. To adjust the backrest and the seat in synchronization, the structure is formed of three pieces 1, 2 and 3 linked together to form an articulated triangle, the vertices of which correspond to the articulation shafts themselves 6, 7 and 8, the latter being the articulation shaft between the piece 3 that supports the backrest and the piece 2 fixed to the support column, which shaft 8 moves in horizontal rotation ("colisa") grooves 10 of the piece 3, allowing the latter to tilt, thereby causing the piece 11 to tilt with respect to the fixed piece 2.
