Abstract:
The invention relates to a mechanism for an office chair or arm-chair, in which control means for the backrest inclination and spring means for biasing the backrest to the position of minimum inclination are provided, in which at least one stepped stop block can be moved in a controlled manner, a step of said block being suitable to interfere with a member connected to the backrest when the same is being inclined, in order to limit the stroke of said member between the position of minimum inclination of the backrest and a position of interference of the member connected to the backrest with a selected one of the block steps. The invention also relates to a method for transforming a locking mechanism to an end-of-stroke mechanism.
