Improvements made to the mechanisms for the swing of armchairs, characterized by the arrangement of a leaf springs, in the form of a wide steel plate occupying the width of the box, pass of support and unión of the structure of the seat, whose iron is joined together with a long protruding protruding fin, coming from the head that is coupled to the upper end of the central column or support leg of the chair, with the possibility of turning in it, said crossbows extending to the vicinity of the lower side of said low support base of the seat, on whose side there is mounted a regulator of the tension of the leaf spring, composed of a transversely arranged cylinder, with its ends supported and guided on the longitudinal walls of the box, in order to facilitate its displacements by means of the bar or screw to the that perpendicularly it is united by its center, whose screw when going threaded in the suitable neck of the referred minor side of the box, makes it possible for the user to regulate the tension of the leaf springs by offering the support of the cross cylinder at different points of it, variables at will.
