Definitions

  • the invention relates to an armchair intended for rest, office work or rehabilitation.
  • the Polish patent specification PAT. 227553 reveals an item of seating furniture comprising a basis, seat and backrest, whose seat is mounted to the base with the use of a ball joint and whose backrest frame is adjustable and equipped with at least one backrest.
  • the backrest frame is preferably equipped with three independent backrests, and the middle backrest is settled on the backrest frame with the use of the ball joint.
  • the purpose of the invention is to create conditions for correction of the posture in the seating position by correcting the forward leaning position to the straight position and ensuring spine movement.
  • the armchair structure according to the invention allows achieving both those targets, i.e. to keep the back straight in the seating position and keep the spine moving.
  • the armchair according to the invention comprises a stable main frame, moveable seat and at least three moveable and adjustable supports: upper, middle and bottom.
  • the armchair is characterised by upper and bottom support mounted on a flexible bar which is mounted to the height adjustment system of the middle backrest (the chest section support) or to the main frame in the area of the middle support.
  • the flexible bar may consist of two parts: an upper part and a bottom part.
  • the upper support (the head support) is a movable cylinder which rotates around its horizontal axis placed in a plane perpendicular to the flexible bar.
  • the upper support may be in a shape of a flat support capable of moving up and down in relation to the flexible bar and rotating up to 30 degrees in relation to the bar.
  • the shape of a cylinder is taken also by the bottom support (the lumbar support) and this cylinder can rotate around its axis.
  • the lumbar support can, just as the head support, take the shape of a flat moveable support.
  • the width of the flexible bar shall not be greater than 15 cm.
  • the armchair can be equipped with a footrest consisting of a flexible bar placed in relation to the base at an angle of at least 15 degrees, optimally 45°-75°, or two matching flexible bars.
  • the footrest can also consist of four flexible bars placed in pairs, with inner bars placed opposite to the outer bars.
  • the footrest may be mounted to the basis with the use of a telescopic or rail system and may be equipped with a movable cylinder or wheels for free movement under the armchair when not in use.
  • fig. 1 presents a schematic drawing of an item of seating furniture as a perspective view with a footrest which consists of two parallel flexible bars
  • fig. 2 shows a footrest which consists of four flexible bars placed in pairs opposite to each other.
  • the piece of seating furniture has a stable main frame 1 , the bottom part of which is the armchair support and the upper part is the place for mounting the flexible bar 6 of the backrest.
  • the seat 2 On the upper edge of the bottom part of frame 1 the seat 2 is mounted.
  • the seat 2 is connected to the basis with the use of a ball joint; therefore, the seat 2 can move in all directions, which ensures the movement of the pelvis of the armchair user.
  • the vertical flexible bar 6 is attached to the upper part of the frame 1 to the upper part of the frame 1 .
  • the bar 6 is attached to the upper part of the frame at the height or in the area where the middle support 4 is attached to the bar. Whereas both the upper and bottom part of the bar 6 are not connected to the frame.
  • Both the upper support 3 and the bottom support 5 have the shape of the cylinder which rotates around its own longitudinal axis.
  • the upper 3 and bottom 5 supports can also take a shape of a flat support capable of moving up and down in relation to the flexible bar 6 and rotating up to 30 degrees in relation to the bar 6 .
  • the range of movement of the upper support 3 in the up and down direction should be not greater than 5 cm. In this case it is about the head movement in relation to the spine, the so called count curtsey - bowing the head and at the same time moving it back. This movement causes a significant reduction in the cervical spine bending forward.
  • the moveable bottom support 5 (lumbar support) stimulates the perception accompanying changes in pelvis position and ensures movement of the lumbar spine.
  • the middle support 4 (support for the chest section) is capable of multidimensional movement which may be ensured for example by attachment of the support 4 to the frame with the use of the ball joint.
  • the bar 6 on which the supports 3 , 5 are mounted, is made of flexible material and therefore the backrest is not stiff and is characterised by flexibility.
  • the width of the flexible bar 6 is up to 15 cm which enables rotation of the spine around the long axis of the bar 6 .
  • the flexible bar 6 may consist of two parts: upper and bottom, with different flexible characteristics and attached in the chest section by applying pressure (small operating forces); therefore, it is possible to adjust the height of the headrest 3 and lumbar rest 5 .
  • the armchair is equipped with the footrest 7 which consists of two flexible bars placed in relation to the basis at an angle of at least 15 degrees, optimally 45°-75°.
  • the footrest can consist of one common flexible bar or of four flexible bars placed in pairs, with inner bars placed opposite to the outer bars.
  • the footrest 7 is mounted in such a manner as to make it possible to pull it out freely to the use position or to place it under the frame when not in use
  • the footrest 7 can be placed, for example, on the rail or have a telescopic connection and can be equipped with wheels, alternatively a travel roller for free movement of the footrest 7 under the armchair when not in use.
