Definitions

  • Certain systems of chair allows a variable slope but authorize only one physical relieving partial of the body, not supporting it in its entirety of the head to the feet or presenting a non ergonomic rigid seat.
  • the system according to the present invention indeed allows an ergonomic support of the whole of the body of the user, involving a relaxation and a muscular and circulatory relieving real whatever the adopted slope:
  • This suspended flexible seat distributes and supports completely the weight of the body and allows a muscular relaxation whatever the selected slope.
  • the system according to the present invention allows an adjustment of the conformation of seat to adjust it with the morphology of its user.
  • the system according to the present invention allows a variable slope, complete and protected of seat, allowing the user to modify the slope of the seat of the sitting position with the reclining position, with all the possible intermediate positions, without risk of inversion in maximum back position.
  • This deformable semi-parallelepiped is defined by the meeting of the 3 rigid parts composing the carriage of seat, fixed and swivelling between them and on the base, this meeting forming 2 symmetrical equilateral semi-quadrilaterals in the 2 parallel plans, their equilateral shape being defined by the equal distance enters the 4 points tops of the 2 quadrilaterals one by one.
  • the parallelepiped thus made up is deformable longitudinally and symmetrically by pivot on the stable base around its 2 fixed higher axes and its 2 lower axes, these 4 axes being parallel and perpendicular to the 2 parallel plans centring the structure.
  • the carriage of seat fixed and swivelling freely on the stable and non deformable base, supports and carries the seat, itself supporting the user. Any deformation and lengthening of the carriage of seat involve the deformation and the lengthening of seat and thus the variation of slope of the position of the user.
  • the 3rd process allows the control of the maximum back variation of the lengthening and the rocker of the whole of the structure carriage of seat: this control is ensured by the existence in butted of 2 stops of safety fixed on the stable and non deformable base against which comes “to butt” the carriage of seat in its high part.
  • the system according to the present invention allows a control and a balance of the slope of the structure seat/carriage of seat by the only weight of the body of the user, without extra mechanism or device.
  • This system is allowed by a process of alignment and interaction on the same axis of the weight of the body of the user in the centre of the seat of the chair and the centre of balance of the carriage of seat.
  • the two points superimposed above define an axis connecting the point of balance of the weight of the body of the user to that of the carriage of seat.
  • FIG. 1 presents the system of this invention in its sitting starting configuration
  • FIG. 2 presents the system of this invention in its variation of maximum slope
  • this system comprises 3 large components:
  • a flexible seat (A), equipped with a head-rest (E) removable and fixed by adjustable side fasteners (L 1 , L 2 ) (laces, pressures or another mode of fastener). This base is fixed and/or suspended on the carriage of seat:
  • T 5 in its 2 ends out of 2 bars (T 2 , T 5 ), so as to slide freely in rotation (brackets or another mode of fixing), T 5 being fixed and removable T 2 to allow the fixing and the adjustment length of seat
  • B 1 a semi rigid parallelogram at 3 sides out of U, supporting seat on its higher side (T 5 ), fixed and swivelling at its 2 lower ends by 2 symmetrical points of rotation ( 4 ), equipped with joints antifriction metal, along an axis (X 4 ), on 2 parallel levels between them perpendicular to this axis, on:
  • B 2 a rigid parallelogram at 4 sides, building the integrated footrest (R) on its front side, equipped with the 2 transverse bars allowing sliding motion (T 3 ) and fixing and the adjustment in length (T 2 ) of seat, B 2 being fixed and swivelling in 2 symmetrical points of rotation ( 3 ), equipped with joints antifriction metal, along an axis (X 3 ) parallel in X 4 , on same the 2 preceding parallel levels on:
  • B 3 a semi rigid parallelogram at 3 sides, its side higher being shifted at its 2 ends towards the interior of the parallelogram to constitute a bar fixes transverse (T 1 ) supporting seat at the level of the knees of the sat user and allowing the free sliding motion of this one in the rocker.
  • B 1 , B 2 and B 3 being assembled and between them such as above, the structure of the carriage of seat thus made up is suspended and fixed on a stable base in the last 4 symmetrical points of rotation 2 by 2 (1 and 2), equipped with joints antifriction metal, along the 2 parallel axes between them (X 1 and X 2 ), themselves parallel in X 3 and X 4 .
  • a stable and rigid base resting on the ground, composed of non deformable symmetrical elements forming mounting and balustrades (F), integrating stops of safety (S) controlling into obstinate the rocker of sat in back position.
  • a symmetrical longitudinal deflection of the parallelepiped made possible specifically by its constitution in 2 symmetrical equilateral quadrilaterals in 2 parallel plans (P 1 , P 2 ) them-even deformable in flattened rhombuses, defined each side by joining their points of rotation 1 - 2 - 3 and 4 , who swivel by rotation on the stable base around the 2 axes (X 1 , X 2 ), like around 2 other parallel axes of rotation (X 3 , X 4 ). These 4 axes correspond to the swing angles of the quadrilaterals ( 1 , 2 , 3 , 4 ).
  • the balance transfer on seat involves the balance transfer of the carriage in the new position of balance.
  • the carriage of seat thus undergoes by rotation around its centre and on its axes a double movement controlled by the weight of the body of longitudinal rocker and lengthening (or rectification) in the direction of the displacement of weight printed by the user.
  • the footrest (R) integrated in the carriage of seat naturally follows the lengthening or the rectification of the carriage, supporting the legs in all the positions.
  • the simple transfer of his body weight by the user thus involves the controlled dynamic tilting of the whole system of seating of the chair, lengthening or rectifying, partially or completely, the chair according to the desired position. All the positions obtained are stable and do not require any effort to be maintained.
