Abstract

A device (101) for mutually locking/releasing either the back or the seat or both, particularly for chairs, comprising a box-like structure (102), which can be associated with a seat and with a stem of a gas-assisted spring, to which a supporting element (103) for a back is articulated in contrast with an elastic element, and comprising a pivot (114), which can move axially in contrast with a first elastically deformable element (113) or a second elastically deformable element (117). A lever (104) is provided, which can be gripped by the user, and which can be associated rotatably with, and which protrudes laterally from, the box-like structure (102). Means adapted to actuate the axial movement of the pivot (114) upon a clockwise or counterclockwise rotation imparted to the lever (104) are associated axially with the lever (104).
