  • the passage of the flexible ply is therefore imposed in this zone 9 of predetermined intersection, and this slot 10 is a return of the flexible ply, able to maintain the transition pan 18 in position regardless of the voltage level of the ply flexible between its two anchor points 17, including when a user is sitting in the seat.
  • the transition portion 18 of the flexible ply has a length greater than the minimum distance between the suspension crossbar 7 and the intersection zone 9.
  • the transition pan therefore forms a belly under the effect of its own weight.
  • the flexible web has sufficient width from one side edge 27 to another to support a user stably.
  • suspension crossbar 7 is near the upper end of the backrest frame.
  • the transition panel 18 also makes a transition between the backrest and the rigid seat surface. Indeed, the flexible ply is tangent with the seating surface. Thus a gradual transition is established by the transition between the flexibility of the backrest provided by the flexible sheet and the rigidity of the rigid seat surface.
  • the rigid seat surface has a rear seat portion extending behind the intersection zone 9, between the intersection zone 9 and a rear edge 25 of the rigid seat surface.
  • This rear seat portion provides user support at the pool.
  • the rear portion of the seat is advantageously inclined towards the rear of the chair.
  • the flexible web adjusts under the effect of user weight and morphology and an anterior portion of the transition pan 18 holds the user's pelvis in position.
  • an anterior portion of the transition pan is in contact with a zone, called the superposition portion, anterior of the rear seat portion, so that said superposition portion extends between the intersection zone 9 and a zone, said stall zone 24, to which the transition panel separates from the rigid seat surface.
  • the anterior portion of the transition panel is wedged between the rear seat portion and the user's buttocks, so that the flexible web is stretched and forms a smooth and continuous transition between the rigid surface of the seat. 'sitting and the folder.
  • the basin of a user is therefore perfectly supported in the superposition portion, wherein the transition pan provides a transition between the rigid seat surface and a backrest. This is all the more the case, as the position of the stall zone (and therefore the length of the superposition portion) is variable depending on the size, morphology and weight of the user.
  • the transition panel 18 is in contact with a zone, called the superposition portion, located towards the front of the rear seat portion only when a user is in the process to sit but is not yet leaning against the seat, as shown in figure 2 .
  • the superposition portion located towards the front of the rear seat portion only when a user is in the process to sit but is not yet leaning against the seat, as shown in figure 2 .
  • the anterior portion of the transition section of the flexible ply is wedged between the user whose weight is exerted on the flexible ply and the rear seat portion.
  • the rear portion of the rigid seat surface being inclined rearward, this intermediate step when a user sits in the seat allows the user's pelvis to be maintained so as to preserve the natural lordosis of the lumbar.
  • the stall zone 24 moves forward to-in certain advantageous configurations such as that shown in FIG. figure 3 - to merge with the intersection zone 9, so that the separated portion is merged with the rear seat portion, and that the superposition portion disappears.
  • the user is thus suspended in the transition pan of the flexible web and the only pressure exerted on the transition panel and that of the weight of the user that is compensated by the reaction of the connecting means 10 and the device 7 suspension.
  • the rear seat portion no longer exerts a direct reaction to the weight of the user (especially directly on the buttocks of the user), the user is sitting comfortably.
  • the pelvis was maintained in such a position that the natural lumbar lordosis was respected in a first stage, and this positioning of the pelvis is then maintained and respected in a second stage, thanks to the support provided by the transition section.
  • the flexible ply extends beyond the intersection zone 9, towards the front of the rigid seat surface, passing alternately above and below the slats 21 forming the rigid seating surface. .
  • the flexible ply also extends beyond the suspension strut 7 and has a support section 19 extending from the suspension strut 7 to a return device 5.
  • the deflection device is advantageously a cross member 5 connecting the two spars 14 of the backrest frame. This cross-beam 5 serves to modify the main direction of the flexible sheet, and therefore, when the flexible sheet is stretched, to obtain a support pan 19 stretched between the suspension crossbar 7 and the cross 5 of return.
  • the flexible web can, depending on the configuration of the seat, go through other references. So for example at the figure 4 , the rear edge 25 of the rigid seat surface forms a return of the flexible sheet.
  • the flexible ply is in particular stretched between two anchoring points 17 to the seat and back frame when a user is sitting on the chair.
  • the flexible sheet is stretched by the weight of the user exerted on the transition pan.
  • the flexible sheet is mounted so as to be slippery on the suspension crossbar and on the cross beam.
  • the flexible tablecloth can slide from front to back (and from back to front) on each of the return devices (cross beam, suspension crossbar, rear edge slat 25 of the rigid seat surface, etc.). In this way, the length of each section of the flexible sheet is automatically adapted to the configuration of the chair and the weight and morphology of the user, each use.
  • the flexible sheet is stretched between its two anchoring points 17, the transition pan elongates forming a more pronounced belly downwards, and the support pan 19 is stretched between the suspension crossbar 7 and the crossbar 5 of referral.
  • the transition pan comes into contact with the support pan on at least a portion of the file formed by the transition pan.
  • the support pan 19 being stretched, it creates additional support for the backrest, so the back of the user, which improves the comfort of such a lounge chair.
  • the length of the transition pan is automatically adapted according to the configuration of the chair.
  • the length of the pan, said pan 20 self-regulation, flexible sheet located between the anchor point 17 located near the rear legs 12 and the rear edge 25 of the rigid seat surface is variable depending on the configuration of the chair.
  • the length of the pan 20 self-regulation depends on the configuration of the chaise longue as can be seen by comparing the figures 2 and 3 to the figure 4 : the pan 20 of self-regulation is longer in sitting configuration ( figure 4 ) in a lying position ( figure 2 and 3 ). Or in a sitting position, the suspension device 7 is further in front of the chair, and therefore the distance between the suspension device 7 and the intersection zone 9 is shorter. Without the self-regulation panel 20 there would therefore be an over-length of the transition pan 18 which would be too big a belly and in any case too low when a user would sit in the seat.
  • the pan 20 of self-regulation can also make it possible to vary the tension felt of the transition pan according to the position of the chair: thus, depending on the arrangement of the self-regulating panel, it could be provided to obtain a softer back in the sitting position than lying down, or vice versa.
  • the flexible ply 3 is anchored at both ends by two anchoring points 17.
  • the anchor points 17 can be made in many ways. However, advantageously in the embodiment presented to Figures 1 to 4 both ends of the flexible web are braided and passed through a slit. A through bar 6 inserted into the ferrule end prevents the ferrule end of the flexible ply from going back through the slot as long as the diameter of the through bar 6 is greater than the width of the slit.
