Definitions

  • Prior art armchairs are classified according to the desired posture.
  • armchairs include: conversation armchairs, lounges and bergeres.
  • the back In conversation armchairs, the back is approximately vertical and indicatively reaches a height slightly above the lumbar region of the user.
  • the back is also approximately vertical but indicatively reaches the shoulders; a headrest is also usually provided.
  • the back In lounges, the back is inclined downwards and a headrest is provided.
  • armchair posture changing mechanisms considerably increases armchair manufacturing costs. Furthermore, armchair posture changing mechanisms may be exposed to malfunctioning and failures.
  • the object of the armchair as described blow is to obviate at least some of the prior art drawbacks and particularly those set out hereinbefore.
  • numeral 1 generally designates an upholstered armchair comprising an upholstered seat 2 and an upholstered back 3.
  • a support frame 4 for the seat 2 and a support frame 5 for the back 3 are provided.
  • the support frame 4 for the seat 2 is substantially rigid and may be formed from a wooden framework encircled at its top by elastic bands (not shown).
  • the framework 4 comprises an ellipsoidal ring 41, a bottom panel 42 and uprights 43, 43, ... 43 that connect the ellipsoidal ring 41 to the bottom panel 42.
  • the padding material for upholstering the seat 2 and the back 3 may be polyurethane foam 9.
  • the seat 2 and the back 3 are covered with a covering, such as fabric or leather, which encloses the padding and the support frame.
  • the outer shape of the armchair is given by the covering of the seat 2 and the covering of the back 3, which form a seamless surface, with no slot or aperture.
  • the support frame 5 of the back 3 comprises a plurality of springs 51a, 51b, 52a, 52b... 52n, 53, which have a flexural behavior and are attached to the support frame 4 of the seat 3.
  • the flexural springs 51a, 51b, 52a, 52b, ...52n, 53 are incorporated in the upholstery of the back 3 and extend from bottom to top to about the upper edge of the back 3.
  • the flexural springs 51a, 51b, 52a, 52b, ...52n, 53 impart elasticity to the whole back 3, from the seat level to the upper end.
  • the user may assume the desired posture and the back 3, which is resilient, makes the posture more comfortable.
  • the portions of the flexural springs 51a, 51b, 52a, 52b... 52n, 53, which project out of the framework 4 are free, i.e. have no mutual connection and may bend independently from one another.
  • the back 3 of the armchair naturally fits any position change of the user sitting on the armchair, thereby affording high comfort.
  • the back 3 has a substantially and/or generally arched conformation, relative to an axis X orthogonal to the seat 2.
  • the back 3 has a first portion 31 of substantially and/or generally constant height, which is adapted to also act as an armrest.
  • the first portion 31 of the back 3 has a height from the seat ranging from about 23 to 26 cm.
  • the back also has a second portion 32 having a progressively increasing height, which is adapted to act as a backrest.
  • the back 3 has a third portion 32 of substantially and/or generally constant height, which is adapted to also act as shoulder rest and headrest.
  • the third portion 33 of the back 3 has a height from the seat ranging from about 55 to 58 cm.
  • the support frame 5 of the back 3 comprises a plurality of flat spring steel bars 51a, 51b, 51c, 52, 52,... 52, 53 having one end (the lower end) driven in the support frame 4 of the seat 3.
  • the flat bars are disposed with the larger surface of the bars approximately parallel to the surface of the back.
  • the lower ends of the flat bars are fastened to the bottom panel 42 by fastener means, such as screws 421.
  • the flat spring steel bars may have a thickness ranging from about 1.5 to 3 mm.
  • the flat spring steel bars have different thicknesses, to impart a differential deformability to the back 3.
  • the first flat bar 51a (inserted in the first part 31 of the back 3), and the last flat bar 53 (inserted in the third part of the back 33) have a greater thickness, e.g. about 3 mm, whereas the remaining bars have a smaller thickness (e.g. about 1.5 mm).
  • At least one, preferably two of the springs 51b, 51c inserted in said first portion 31 of the back 3 include two flat spring steel bars (e.g. two flat bars, each 1.5 mm thick) joined together to obtain a total thickness of about 3 mm.
  • the flat bars 51a, 51b, 51c, 52, 52, ...52, 53 are introduced into slot holes formed by milling.
  • shims 422 are added to eliminate any clearance.
  • At least some of the flat bars 51a, 51b, inserted at the first portion 31 of the back 3 have a free end folded (e.g. to form a 90° angle) for improved support of the part of the back that is designed to also act as an armrest.
  • the flat spring steel bars 51a, 51b, 52a, 52b, ... 52n, 53 are driven into seats arranged over a portion having a conical section, e.g. along a portion of an ellipse.
  • the flat spring steel bars 51, 51b, 52a, 52b, ... 52n, 53 are disposed with lower ends that tend to converge and upper ends that tend to diverge.
  • the armchair is constrained to a rotating base 6, such as a metal rotating base having a ball bearing.
  • Rotating bases for armchairs are known in the art and will not be further described.
  • the first portion 31 of the back 3 is the one to the left of the user, whereas the third portion 33 of the back is the one to the right of the user.
  • the armchair may have an inverted profile, so that the portion of the back that can be also used as an armrest is the right portion and not the left one.
