- the suspension device requires the passage of the flexible sheet in this area.
- the suspension device according to the invention is adapted to bear the weight of a user.
- intersection zone is located in front of the suspension device.
- intersection zone is generally linear, and the suspension device too.
- the vertical plane comprising the intersection zone is located in front of the vertical plane comprising the suspension device. So that the transition pan truly forms a smooth transition from back to front, from top to bottom, between the bottom of the backrest and the back of the seat.

- the length of the portion of superposition, in which the flexible sheet is in contact with the rigid seating surface varies in particular according to the configuration of the seat, the morphology and the weight of the user.
- the user By then backing into the seat, the user will deform the transition pan which - being flexible but rigid in traction (inelastic) - adapts to its morphology and its weight. At least a portion of the belly formed downwardly by an anterior portion of the transition pan will then be lifted, so that the user's pelvis is lifted and held in a forward facing position for the sake of lordosis compliance. lumbar. Indeed, the legs of the user are then at least partly in rubbing contact with the front portion (located at the front of the separation zone) of the rigid seat, and prevent the pelvis from being rotated to the 'back.
- a correct position of the lumbar is therefore naturally adopted from the first sitting step in a seat according to the invention and is then maintained whether or not the flexible ply is in contact with said superposition portion.
- the length of the transition pan is adapted so that, when a user sits in the seat, the transition pan comes into contact with said superposition portion.
- the length of the transition panel is chosen long enough to form a belly down - particularly lower than the front seat portion - and coming into contact with the rear seat portion to comfortably seat the buttocks of a user, while being short and tense enough to give him a feeling of support.
- the length of the transition panel is at least 5% greater than the distance between the suspension device and the intersection zone.
- the separation zone and an area in which the transition portion of the flexible ply detaches from contact with the rigid seat surface.
- the separation zone divides the rear seat portion into: a separate portion extending from the rear edge of the seat to the separation zone, in which the transition section is suspended above and without contact with the rigid seating surface, and
- the position of the separation zone (and therefore the extent of the separation and superposition portions) between the rear edge of the seat and the intersection zone is variable depending in particular on the configuration of the seat, the morphology of the seat. user and the weight of the user.
- the position of the separation zone between the rear edge of the seat and the intersection zone is variable during the movement of a user to sit in the seat.

- the length of the transition panel is less than the sum plus 5% of the distance between the suspension device and the rear seating edge and the distance between the rear seating edge and the intersection area, so that the separation zone is distinct from the rear edge of the seat.
- the separation zone therefore extends strictly between the rear edge of the rigid seat surface and said intersection zone.
- the flexible web (and therefore in particular the transition panel) is advantageously tensioned by the weight of the user, so as to support at least part of the user.
- the pan of transition of the flexible tablecloth makes it possible to create a flexible transition between backrest and seat. Indeed the transition pan adapts to the curvature of the lower back.
- the transition zone between backrest and seat is an essential area of comfort of a seat - especially a chair whose backrest and / or seat is rigid. Indeed, this area welcomes the lumbar vertebrae of the user - highly sought after because they support a large part of the weight of a person.
- the lumbar of the user is supported only by a flexible sheet, but the overall rounded shape that the tablecloth takes under the effect of the weight of the user does not respect lumbar lordosis (forced kyphosis of the lumbar).
- the flexible sheet is held by a bar at the front of the seat particularly uncomfortable for the legs.
- the lumbar is not supported because they usually have a spacing between backrest and seat.
- a good support for the legs and buttocks of a user is provided by a rigid seat, and effective and comfortable lumbar support is provided, including support that respects the lordosis of the lumbar.
- the lateral edges of the transition pan are free edges.
- the transition pan thus adopts a shape perfectly adapted to the morphology of a user.
- the length of the transition panel, and the shape of the rear seat portion are further advantageously adapted so that the separation zone is at the front of the suspension device so that the angle formed by the dihedral trunk- the thighs of a user sitting in the seat is greater than or equal to 90 °. Such an angle, ensures a comfortable seat and a good position of the vertebrae.
- the rear seat portion and more particularly the superposition portion has a slope inclined downwards towards the back between 2 ° and 45 ° relative to the horizontal when the chair is placed on a horizontal floor by its legs, in particular about 30 °.
- the rear seat portion has a minimum depth, from the rear edge of the rigid seating surface to the intersection area of approximately 10cm
- the front seat portion has a minimum depth, from the intersection area to the front edge of the surface rigid seat, about 5cm.
- the flexible sheet forms at least a second panel, said support panel, extending at the rear and near the transition panel, between the suspension device and a device forcing the passage of the flexible sheet at this location, so that, the flexible sheet being stretched, the support pan increases the firmness of a portion of the backrest formed by the transition pan.
- the support pan doubles the transition pan, especially on the back part formed by the transition pan.
- the user of a seat according to the invention has a reinforced support in the lower back: the tensions of the transition pan and the support pan accumulate in this area and provide better support of the lumbar vertebrae.
- the support panel allows in particular to respect the natural lordosis of the back lumbar region.
- the support panel is advantageously disposed behind the portion of the backrest formed by the transition panel, a few centimeters from it, so that the transition pan and the support pan are superimposed.
- the transition pan adapts to the shape of the user.
- the transition pan deforms slightly backward, so as to come into contact with the tense support pan, which provides additional support at least on the transition pan's portion of the backrest. .
- the support section is advantageously stretched between the suspension device and a device forcing its passage in the bottom of the seat, for example near the crossing zone.
- a device acts as a return of the flexible sheet, that is to say it allows to change the main direction of the flexible sheet.
- Such a device is for example formed of means for anchoring the flexible web, or a cross-member of the flexible web on which the latter can slide, or other.
- a seat according to the invention advantageously comprises a frame adapted to be placed in at least two different stable configurations, the length of the transition pan being variable depending on the configuration of the seat.
- the inventor has succeeded in producing a seat with a variable configuration whose seat is rigid and at least a portion of which is made with a flexible sheet.
- Self-regulation that is to say, the automatic adjustment according to the configuration of the seat - of the length of the transition panel according to the configuration of the seat is a particularly advantageous and specific effect of the invention, obtained in a simple way.
- Such a seat therefore advantageously has a first position, called sitting position, in which the backrest is higher than in a second position, said extended position, in which the file is more recumbent.
- the flexible sheet can slide back and forth (and from back to front) through or on the suspension device.
- the length of the transition panel and the tension of the transition and support panels adapt spontaneously according to the configuration of the seat, the weight of the user, etc. without the user needing to perform a specific action of adjusting the flexible sheet, in particular without the need to pick up and hang up the flexible sheet.
- the flexible sheet can be properly stretched when a user sits in the seat, advantageously and according to the invention, two separate portions of the flexible sheet are anchored in the seat.
- the flexible sheet is stretched between these two anchoring zones when a user sits in the seat.
- the support and transition sections are between these two anchoring zones.
- the frame of the seat comprises the back frame and the rigid seat surface, but also a support frame of the rigid seat surface, legs, etc.
- the frame of a seat according to the invention may be in one or more parts, and the anchoring of the flexible ply can be carried out at any point of the seat.
- a seat according to the invention is also characterized in that the connecting means of the intersection zone comprise at least one slot passing through the rigid seat surface, the flexible sheet being mounted in passing through this slot.
- the flexible sheet passes into a slot made substantially parallel to the crossing zone between the directions defined by the backrest and the seat cushion.
- a slot is substantially parallel to the suspension device of the flexible sheet.
- the rigid seat surface may have several slots in order to adjust the extension of the transition panel to the front of the seat, choosing the slot in which the flexible web passes.
- the flexible sheet is advantageously anchored to the frame of the seat in a portion beyond its passage through the slot relative to the transition pan.
- This slot serves as a reference to the flexible sheet and requires the passage of the latter in a well-defined intersection area with the rigid seat surface. That is why it is a means of joining the flexible sheet with the rigid seat surface.
- the transition panel has a length between the suspension device and the intersection zone strictly greater than the minimum distance between the suspension device and the intersection area.
- the flexible sheet is elastic in its longitudinal direction.
- it is longer than the minimum length between its two anchoring zones, so that it adapts to the different configurations of the seat, as well as the shape and weight of a user.
- the transition panel has a length greater than or equal to the shortest distance between the suspension device and the connecting means.
- the transition pan thus forms a belly.
- the use of a flexible rigid sheet in traction makes it possible to provide a better comfort for the user.
- a flexible sheet may be a fabric for example.
- the frame of a seat according to the invention advantageously comprises:
- a rigid backrest frame different from the rigid seat frame, and comprising the device for suspending the flexible sheet, said seat and backrest frames being assembled relative to one another so as to able to form at least one stable configuration of the seat in which they intersect in the crossing zone, the backrest frame extending upwards with respect to the crossing zone, and the seat frame having a rigid surface sitting in front of the crossing zone.
- the seat frame has the rigid seat surface in front of the crossing zone.

- the backrest frame may be useful only support the suspension device, the entire backrest being formed by the flexible sheet, via its particular transition panel.
- the seat frame has a generally elongated shape and forms a rear base of the seat
- the backrest frame has a generally elongated shape and forms a base before the seat.
- the seat and backrest frames of a seat according to the invention advantageously have elongated shapes, defining intersecting surfaces in the crossing zone, or in the vicinity of the latter.
- the rear and front legs of the seat form at least three points of non-aligned support to ensure the stability of the seat on the ground.
- a seat may have two points of support for the front legs and two points of support for the rear legs.
- said seat and back frame structures have assembly means allowing them to slide relative to one another to move from a stable configuration of the seat to another configuration stable seat.
- Such assembly means can be of any kind since they allow a sliding of one frame relative to the other to move from one configuration of the seat to another, as well as a blocking of the frames. relative to each other to maintain a stable configuration of the seat.
- the crossing zone is generally mobile depending on the configuration of the seat.
- the backrest frame is adapted to slide along the seat frame to move from a stable configuration of the seat to another stable configuration of the seat.
- the back frame has grooves and the seat frame has tabs, the grooves and tongues being adapted so that:
- the tongues can slide longitudinally in the grooves to move from a stable configuration of the seat to another stable configuration of the seat,
- the tabs can jam by jamming in the grooves for each configuration of the seat between at least a first and a second stable configuration of the seat.
- the grooves are advantageously wider than the tongues with which they cooperate. This facilitates the sliding of the tongues in the grooves but also to allow a locking of the tongues in the grooves by buttressing the tongues in the grooves.
- the bracing occurs when the main direction of a tongue is not collinear but sufficiently secant with the main direction of a groove. When a tongue is braced in a groove it can not slide anymore in the latter and the blocking makes it possible to maintain the seat in a stable configuration. Blocking by arching is advantageously all the stronger when a user is sitting in the seat.
- the seat frame comprises a rigid frame comprising two side rails:
- the backrest frame comprises a rigid frame comprising two side rails:
- the backbone extends from the back where it forms a rear leg, in front where it has the rigid seat surface.
- the backrest frame it extends from the front of the seat where it forms a base before, upwards and substantially towards the rear where it comprises the device for suspending the flexible sheet. Their crossing defines the crossing zone.
- the side rails of the seat frame are preferably sliding in grooves formed on the inner face of the longitudinal members of the back frame.
- the sill members of the seat frame and the grooves of the back frame are adapted to cooperate so that a user can change the seat configuration easily by sliding the seat frame relative to the seat frame. back frame, and so that the side members the seat frame can be jammed in the grooves of the back frame.
- Such an arrangement allows in particular for a seat according to the invention to adopt all possible configurations between a seated extreme position and an elongate extremal position. Indeed, the adjustment of the configuration of the seat is not done through predetermined notches but gradually at any point of the spar of the seat frame between its two extremal positions.
- the flexible ply is anchored to the seat frame, close to the rear base,
- the flexible ply is anchored to the seat frame in the front half of the rigid seat surface.
- the flexible sheet extends from its anchor point near the rear base to the device for returning the flexible sheet located near the crossing zone, forming the beginning of the support section.
- the support section extends in continuity, from the return device to the suspension device.
- the transition panel extends in continuity with the support panel, from the suspension device to the zone of intersection with the rigid seat surface, the intersection zone being advantageously formed of a through slot in the surface. rigid seat, through which passes the flexible web.
- the flexible ply extends after this intersection zone to its anchor point on the seat frame in the front half of the rigid seat surface.
- the flexible web passes through other slots and / or devices referrals.
- the flexible sheet may go through several successive references for technical and / or aesthetic reasons.
- the additional lengths of flexible sheet extending beyond the support and transition panels allow to adjust the length of the latter according to the configuration of the seat.
- the sliding connection between a rear support panel and the transition panel can allow to adjust the length (and therefore the tension) of the transition pan according to the configuration of the seat.
- the flexible sheet can pass several times above and below the rigid seat surface, through the slots separating slats constituting this rigid seat surface, allowing in particular an aesthetic transition between flexible sheet and surface rigid seat.
- the flexible sheet may be anchored to the backrest frame, near the front frame instead of being anchored in the front half of the rigid seat surface.
- Such a configuration with double frame and blocking by bending between at least two different positions is particularly advantageous when the seat according to the invention is a lounge chair.
- the material and the anchoring zones of the flexible ply are chosen so that when a user sits on the seat, in at least one stable configuration of the seat, said flexible ply adopts a shape adapted to ability to support the back of the user and gradually bring the user's buttocks to support on the rigid seat surface, so that the user is in contact with the flexible sheet but sitting on (and therefore supported by) the rigid seat surface.

- - Figure 7 is a schematic view of three-quarter straight profile of the third embodiment of a seat according to the invention and Figure 6, in a transport configuration.
- the seat is a lounge chair.
- the chaise longue has two intersecting frameworks: a backrest frame 1, and a seat frame 2 intersecting in a crossing zone 4.
- the backrest frame 1 comprises two side rails 14 forming a base 13 front by one end, and interconnected by slats 11.
- the slats 11 can strengthen the structure of the backrest frame and can also have an aesthetic role.
- the two rails 14 of the backrest frame 1 are connected, near their upper end, opposite to the base 13 before, by a suspension device in the form of a crossbar 7 suspension.
- the seat frame 2 comprises two side rails 15 forming rear legs 12 at one of their ends, the two side rails 15 being interconnected by slats 21.
- the seat frame has a plurality of slats 21 spaced apart by thin slits, the slats 21 forming a rigid seat surface 8 which extends from a rear edge 25 to a front edge 26.
- the back frame 1 and the seat frame 2 are assembled to one another in a crossing zone 4.
- the longitudinal members 15 of the seat frame are slidably mounted in grooves 16 made substantially transversely in the longitudinal members 14 of the backrest frame.
- the grooves 16 of the back frame have a width greater than the width of the side members 15 of the seat frame.
- the back frame By substantially aligning the longitudinal directions of the grooves 16 and longitudinal members 15 of the seat frame, the back frame can slide back and forth along the base frame. In this way, a user can move the lounge chair from one stable configuration to another, for example from a first elongate configuration shown in FIGS. 2 and 3 to a second raised configuration (more seating) shown in FIG. 4.
- the stable configurations of the chair are obtained by bridging the side rails 15 of the seat frame in the grooves 16 of the back frame.
- the seat and back frame frames are positioned relative to each other in such a way that - as shown in Figures 2 and 3 - each spar 15 of the seat frame is blocked in the grooves 16 of the backrest frame.
- Each spar 15 of the seat frame is in non-sliding contact at two locking points: on the upper rear portion of the groove in which it is mounted and on the lower front of the same groove.
- an interlocking blockage the greater the normal force between a sill of the seat frame and the groove of the back frame (at the two locking points), the greater the blockage according to a Longitudinal direction of sliding is strong. So when a user is sitting in the chair, the jamming is stronger, and the chair is more stable in its configuration.
- the two lower front and upper rear contact points between a spar and the edges of a groove are spaced apart, and therefore when the groove is longer.
- the rails 14 of the back frame are widened at the grooves 16.
- the grooves 16 are longer and the maintenance of one frame with respect to the other by buttressing is better.
- such enlargement of the spars of the back frame in the crossing zone allows for more or less pronounced armrests to help the entry and exit of the seat for a user who can rely on it.
- armrests locally reinforce the rails 14 of the back frame in which it is then advantageous to practice the grooves 16 assembly with the base frame. It is particularly advantageous to have spars 14 of the backrest frame reinforced in the crossing zone, subjected to high stresses when a user is sitting in the chair.
- the rails 14, 15 of the seat and back frames have upper and lower rounded edges to provide better comfort and improved aesthetics.
- the grooves 16 therefore also have a high and low gutter shape to accommodate the longitudinal members of the foundation frame. The bracing is thus reinforced because the contact surface between a spar and the gutters of a cooperating groove is increased.
- the groove shape of the grooves 16 allows lateral guidance of the longitudinal members 15 of the seat frame.
- the width of the side members of the seat frame is smaller than the width of the spars of the back frame (at least at their cross with the back frame and therefore at the grooves , and if necessary, armrests).
- Such a method of assembly of the seat and back frame allows to configure the chaise longue in any position between two extremal configurations corresponding to: the most sitting configuration on the one hand and the most elongated configuration of 'somewhere else.
- the deckchair is equipped with a flexible sheet 3, at least one transition piece 18 of which extends between a zone 9 of intersection with the surface. 8 rigid seat, and a crossbar 7 suspension.
- the lateral edges 27 of the flexible sheet and more particularly of the transition pan are free, that is to say they are neither guided nor elastically recalled.
- the seat has connecting means consisting of a slot 10 formed by the interval between two successive slats 21 in the area 9 of intersection with the rigid surface 8 of the seat.
- the flexible tablecloth 3 passes into this slot 10, so that the flexible sheet always has the same area 9 of intersection with the rigid seat surface.
- 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.
- the suspension crossbar 7 is close to 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 panel is in contact with a zone, called the superposition portion, anterior of the rear seat portion, so that said superposition portion extends between zone 9 intersection and an area, said stall zone 24, which the transition pan 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 backed in 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 backed in the seat, as shown in Figure 2.
- the front portion of the transition portion 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 like the one shown in FIG. 3 - to be confused with the intersection zone 9, so that the separated portion is merged with the rear seat portion, and that the superposition portion disappears.
- User is therefore suspended in the transition pan of the flexible web and the only pressure on the transition pan and that of the weight of the user who is compensated by the reaction of the connecting means 10 and the suspension device 7.
- 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.
- 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. Indeed, the flexible sheet is mounted so as to be slippery on the suspension crossbar and on the cross beam.
- the flexible web can slide back and forth (and from back to front) on each of the deflection 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 tablecloth is automatically adapted to the configuration of the chair and the weight and morphology of the user, with each use.
- transition pan 18 In particular when a user sits on the chair, so on the transition pan 18, as shown in Figure 2.1a flexible sheet is stretched between its two anchor points 17, the transition pan elongates forming a belly more pronounced down, and the support pan 19 is stretched between the suspension crossbar 7 and the cross 5 of return.
- the transition pan comes into contact with the support panel on at least a portion of the file formed by the transition pan.
- the support pan 19 being stretched, it creates additional support of the backrest, so the back of the user, which improves the comfort of such a deck 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 of self-regulation depends on the configuration of the chaise longue as can be seen by comparing FIGS. 2 and 3 in FIG. 4: the pan 20 of self-regulation is longer in sitting configuration (FIG. 4) in an extended 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 there would therefore be an extra length of the transition pan 18 which would be too big a belly and in any case too low when a user sat 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 provision of the self-regulating panel, it could be provided to obtain a file more flexible 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 shown in Figures 1 to 4, the two ends of the flexible ply are brazed and passed through a slot. 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.
- a lounge chair according to the invention shown in FIGS. 1 to 4 comprises:
- a wooden backrest frame 1 having a linear length of approximately 180 cm, a radius curvature of approximately 1.5 meters, and whose spars have on average a section of 5 cm ⁇ 8 cm, widened at the level of grooves 16 to have a section of about 5 cm x 24 cm,
- a wooden seat frame 2 having a linear length of approximately 130 cm, a radius curvature of approximately 1.1 meters, and whose spars have on average a section of 3 cm ⁇ 5.5 cm,
- a flexible sheet consisting of a web of fabric that is substantially inextensible (rigid in tension), of total length from one anchorage point to another of about 3 meters, the transition section of which has a length of suspension at the intersection zone - between 115 cm and 130 cm in the elongated configuration of Figures 2 and 3, and between 95 cm and 110 cm in the seating configuration of Figure 4, the possible variations being relative to the weight of the user of the chaise longue,
- a rigid seat surface 8 approximately 55 cm wide and about 100 cm long including a rear seat portion between the zone
- the grooves have a length of about 23 cm, and a width of about 5.9 cm.
- such a chaise longue can be presented in the form of a kit of elements to assemble.
- the slats 11, 21, the longitudinal members 14, 15 of the seat and back frame, the crosspieces 5, 7 of return and suspension, the flexible ply 3, the anchoring bars 6, can be assembled together. to each other for example by pieces of hardware and / or self-assembly (folding, interlocking, ).
- these elements can be arranged in a transportable volume, in particular of restricted thickness, for example less than or equal to 10 cm.
- the rails 14, 15 of the seat and back frame can each consist of two assemblable elements (folding, interlocking, ...) to reduce their size to the packaging and sales, so that ability to market such a chair in a substantially parallelepiped packaging having dimensions of about 100 cm x 60 cm x 10 cm.

- She comprises means for joining the flexible ply with the rigid seat composed on the one hand of a slot 10 in the rigid seat, the flexible ply is mounted in said slot, and on the other hand anchoring means 17 at one end of the flexible ply beneath the seating surface at said slot 10.
- the rear seat portion is adapted to support the buttocks of a user who sits on the chair. Indeed, under the effect of its own weight and more particularly under the effect of the weight of a user, the flexible ply 3 deforms and comes into contact, in its lower front part, with a zone, said portion of superposition , anterior of the rear seat portion extending from the intersection zone 9 to a stall zone 24 between the flexible ply and the rigid seat surface 8. Indeed, there is in this area a superposition of the flexible ply 3 and the rigid seat surface.
- the rigid seat surface is advantageously inclined downwardly towards the rear, so that the rear seat portion and more particularly the superposition portion are also inclined downwards towards the rear, in particular with an angle of about 5 ° from the horizontal when the chair is placed on a horizontal floor by its four legs 22.
- the length of the flexible ply is further selected so that the lower anterior portion of the flexible ply forms a downwardly extending belly extending horizontally below the front seat portion.
- the length can be chosen so that, when a user sits in the chair, the superposition portion is non-zero, that is to say that the user's buttocks are supported by the rigid seat, that is about 15cm for the chair model shown in Figure 5.
- the length can also be chosen so that when a user sits in the chair, the superposition portion is zero, that is to say that the buttocks of the user is suspended in the flexible sheet, a length of about 15cm for the chair model shown in Figure 5.
- the flexible ply 3 is anchored at both ends of the transition panel 18, by anchoring means 17 at the suspension device 7 and the intersection zone 9.
- the anchoring means are identical to those of the first embodiment: the flexible ply 3 is mounted in a slot of the backrest 1 and the surface 8 of rigid seat and form, after the slot (that is to say respectively at the back of the file and under the seat surface), a loop on a bar 6 through diameter greater than the width of the slots.
- the seat is a folding chair.
