Abstract

Actuation device for the articulation of footrest of relax armchair, which is applicable in that type of armchairs that have a structure in functions of general framework for the assembly of the seat, the footrest and the own backrest, counting on a deformable quadrilateral and later for the assembly of the own backrest, as well as with articulated mechanisms based on pairs of connecting rods for mounting the footrest, being mounted on the free end of those pairs of connecting rods respective profiles where the assembly of the constituent part is made of the footrest, and wherein said articulated mechanisms can be folded and deployed, being retained in the first case by means of ratchets driven through an axis, producing in that actuation the release of the articulated mechanisms themselves to achieve the overall extensibility of the footrest, it is characterized because the axle on which the loaders are mounted the locking elements of the articulated mechanisms of the footrest assembly are linked to a manually operated lever which is located in correspondence with the internal part of one of the armrests, a lever of which a vertical arm forms part of the inside of the armrest. The armrest itself is linked to the axis of the pawls in correspondence with a cassette provided inside said armrest. 2.action device for the articulation of footrest of relax chair, according to claim 1, characterized in that between the profiles arranged on the free ends of the pairs of articulated rods that form the articulated mechanisms of the footrest, and on whose profiles remains the own footrest, there is provided a crosspiece between these profiles, which assists in the assembly of such footrest and in the stabilization and centering thereof. 3. Actuating device for the articulation of footrest of relax chair, according to previous claims, characterized in that it has a lower support frame with means for mounting the respective armrests of the chair. 4. Actuating device for the articulation of footrest of relax chair, according to previous claims, characterized in that the classic springs that are related to the deformable quadrilaterals of the support and mounting of the backrest, are fixed by their opposite end to the one of fixation to the static structure. General, to paths and elongated lateral plates linked articulately with the deformable quadrilaterals, determining a means of transmission of movement to these deformable quadrilaterals for the inclination of the backrest when the carrier shaft of the locking pawls and release of the articulated mechanisms of the footrest is actuated .
