DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention refers to an armchair, of the type provided with a reclinable backrest and an articulated footrest, for home or office use, or further for use in transportation means, such as buses or airplanes.
BACKGROUND OF THE INVENTION
In similar armchairs of the state of the art, the footrests articulate between an operative or extended position, and a retracted position, where they project downwards, generally ortogonally from the armchair seat.
Such armchairs present several limitations. Firstly, the upright retracted position of their footrests is uncomfortable to the user, since it hinders the free movements of his feet.
A second shortcoming of these armchairs refers to the fact that their footrest retracting mechanism is coupled with the their backrest reclining mechanism, whereby the footrest will only be fully extended at the fully reclined position of the backrest. Consequently, at the intermediate reclining positions of the latter, the footrest is also at an intermediate position, which also makes its use very uncomfortable.
A third drawback of these known armchairs owes to the fact that their downward projecting footrests are considerably detrimental to the aesthetics of the assembly.
In a further aspect, the pendent footrest when use in the known armchairs in transportation means, such as airplanes, closes the space under the seat, usually used by the passengers to store personal luggage. Furthermore, the known armchairs are deficient regarding user's comfort: in their great majority, the adjustment of the backrest is only possible in predetermined positions, obtained through dented wheel mechanisms, where such positions do not usually coincide with the desired most comfortable position. The known millimetrically adjustable backrest armchairs generally use an endless screw mechanism, actuated by the user through rotating an actuator knob. This is a very uncomfortable operation to the user, inasmuch as it requires a large number of turns of said knob in order to displace the backrest along its entire course. Hence, it is a general object of the present invention to provide an armchair, of the type provided with an adjustable backrest and an articulated footrest, wherein said footrest,in a retracted position, does not interfere with the functionality and the aesthetics of the armchair.
It is a particular object of the present invention to provide an armchair, as described above, which permits the user to combine any possible position of the backrest with a comfortable position of the footrest.
It is also an object of the present invention to provide an armchair, as described above, the footrest position of which, in its retracted position, permits free movements of the user's feet, thus providing for a comfortable seat.
It is also a further object of the present invention to provide an armchair, as described above, extremely versatile, due to the layout of its footrest in a retracted position, making it adequate for use in transportation means, such as airplanes, as well as in non-vehicular uses, such as in homes, offices, auditoriums, among others.
It is an additional object of the present invention to provide an armchair, as described above, carrying a backrest millimetrically adjustable through a mechanism extremely simple and comfortable to the user.
SUMMARY OF THE INVENTION
These and other objects and advantages of the present invention are attained through the provision of an armchair, comprising: a base; a support frame, forming a framework to be fixed under the seat of an armchair portion.
According to the invention, the armchair is provided with: a flat frame-shaped footrest, comprising: a first footrest portion, rearly articulated with the forelower region of the support frame, in order to be angularly displaced between a non-operative position, inferiorly adjacent to the support frame, and an operative position projecting forwards from the armchair portion; and a second footrest portion mounted onto the first footrest portion, to be linearly disp
