Definitions

  • the present invention relates to a furniture device for body support, in particular seat or chair furniture trigger, including body support plates which are each consisting of mutually elongated support elements coupled and arranged in parallel and oriented transversely relative to a longitudinal axis of the device, a chassis, and coupling means for coupling the dishes of aforementioned support to the aforementioned chassis.
  • the cushion certainly takes the form of the back.
  • the deepest parts of the cushion exert pressure higher on the back than the less sunken parts, especially at the level of the lumbar region. Again arises the same problem that the back muscles are found under tension and the user starts to fidget, and tries to move the seat plane even further forward while sinking further and further until the lower back is completely without support.
  • Sitting for a long time just like standing for a long time represents a heavy body burden.
  • the body needs movement to remain flexible.
  • a good backrest and a good seat should therefore adopt the shape of back and side, and thus provide support uniform on all exposed parts of the body. This characteristic should be maintained when the user move and adopt different attitudes.
  • Comfort devices of the aforementioned type are already known.
  • the existing beds however relate to systems with slats which must support a mattress or which more general require a soft mid layer.
  • the most existing systems except that of Milton Luchenski (United States of America) and J.M. Reau (France) has slats which rest on supports, which move back and forth in an element of guide. The slats all pivot on the supports. The movement of the supports is only one-dimensional.
  • the slats are in mutually independent movement.
  • the slats pivot in a certain direction, either under the pressure of the mattress, or by an elastic material with which they are connected. It results in a lack of flexibility for existing furniture.
  • each set of aforementioned elongate support members is suspended by means of an action suspension system multiple.
  • This consists of a suspension of first level with external coupling by pair of support elements mutually adjacent by means of pieces of primary intermediate suspension on the one hand, and at least an additional second level suspension with coupling exterior by pair of aforementioned intermediate parts which are mutually adjacent, by means of suspension parts additional secondary.
  • the successive elongated support elements are each linked directly to each other along their longitudinal sides by suitable connecting means.
  • the comfort device according to the invention, it achieves a fully continuous support plate surface thus promoting user comfort.
  • the support plate of the device to take the shape of the body when it comes into contact with it, and more precisely when the user takes a position on or against the aforementioned support dish.
  • the support plate follows in continuous body movement and an excellent distribution of pressure on the body is obtained.
  • the movement intermediate suspension parts should be considered in two modes in the sense that a superposition of movements waveforms on different levels is carried out, so that the support elements perform a wave movement of overlay which adapts precisely to that of the body.
  • the means of direct connection mentioned above are formed by articulation links of the hinge type. These means are particularly suitable well to the suspension systems implemented in the device according to the invention thus further increasing more user comfort. According to a mode of equally advantageous embodiment of the invention, so does the same for the intermediate suspension parts constituting the suspension system.
  • the overlapping arrangement which is preferred for intermediate suspension parts by compared to the corresponding pairs of elongated elements of support, is produced in a plane substantially common to elongated elements mentioned above on the one hand and piece corresponding primary intermediate on the other hand.
  • each support plate consists of elongated elements, which are mutually prioritized by set functional in elements from level 1 to N in which the first level elongated elements have the function unique body support, the elements of others levels essentially having a function of connection, in particular by articulation, and suspension.
  • the connection arrangement between elongated elements belonging to different but successive levels is respectively achieved by an overlapping bond of two elongated elements mutually adjacent by means of a link element belonging to a level immediately superior. Two elements lying down from the next higher level are at their tower connected to overlap by another elongated element belonging to a hierarchical level yet higher than the latter.
  • the connecting elements are elongated and arranged transversely to the elongated support elements and in substantially the same plane as these, and laterally with respect to these, so that they too can serve as elements support, but lateral.
  • This peculiarity could be particularly useful in the case of a seat.
  • the slat gauge narrows from end to end the other. This variation of template all slats can be very advantageously used to take into account the structure of the body, the parts narrowed ends of each support plate being arranged to match the ends respective of the body.
  • both the supporting elements and the connecting elements or intermediate pieces of each above mentioned hierarchical level homogeneous. This allows optimization of useful surface of comfort for the user while ensuring minimal bulk thanks to the absence elements in additional layout plans.
  • all the aforementioned articulation means both those who articulate the intermediate parts aforementioned among themselves as those which connect these to the aforementioned elongated support elements, are formed by axes all oriented along the direction of the longitudinal axis of the elongated element of support. This allows orientation by pivoting on their longitudinal axis of the elongated support elements in cases of solicitation of these by the body burden of a user.
  • the aforementioned direct connection means are formed by a flexible element.
  • Other features and advantages of this alternative mode are defined in the subclaims corresponding.
  • the present invention relates to comfort devices of all types such as armchairs, beds, and other applications, in which a comfort interface acting as a buffer between part of the human body and an external element can itself constitute the charge or on the contrary in which it is the body which constitutes the charge.
  • a comfort interface acting as a buffer between part of the human body and an external element can itself constitute the charge or on the contrary in which it is the body which constitutes the charge.
  • the description will be more oriented on the armchairs, for the sake of convenience and clarity.
  • the seat illustrated in FIG. 1 has a backrest 11 and a seat not shown.
  • Each of these elements constitute a support plate 11, 12 as illustrated in Figure 9.
  • Each support plate 11, 12 has a series of mutually parallel and arranged slats 3 horizontally, which are preferably linked together by a hinge link 20. All slats are connected to a central articulation point 24 by a lever system 31, 32, 33.
  • the slats 3 are directly connected to each other by hinges 20.
  • the slats should not all have the same shape. They can be flexible and can be made in wood or even another material, if necessary in being covered with a soft or decorative material. These 3 can however be used perfectly of direct support elements for the body.
  • the backrest consists entirely of slats as visible in Figure 1.
  • the slats support 3 mutually parallel and horizontal.
  • the aforementioned connecting elements 31, 32, 33 also consist of slats but arranged as for them transversely with respect to the slats of support 3 as shown in Figure 1.
  • the support slats 3 are mutually connected from direct way by direct connection means 120 and indirectly by the suspension slats, 31, 32, 33.
  • the direct connection means 120 are advantageously constituted by flexible elements of the cord type which cross right through each of the slats of support 3 over the entire height of the backrest 11 and substantially parallel to the longitudinal axis thereof.
  • the indirect connection means consist of an articulation link 21, 22, 23, 24. They can advantageously be constituted by small axes when they serve as means of articulation between a pair of slats 3 and a link / suspension element 31. These 21, ...
  • support slats 3 itself narrowing from one end of file 11 to the other, which corresponds perfectly to the morphology of the human body, which also has two ends, the head and the feet, which are going to shrink from the central area of this one, arms included.
  • Armchairs are generally designed to present on the one hand a dossier 11 substantially corresponding to the upper half of the body and on the other hand a corresponding seat 12 substantially at the bottom half.
  • Suspension slats 31, 32, 33 are indeed perfectly suited to the elongated morphology of the arms. So we get a seat template which is both perfectly suited to body morphology while providing that same body a multiple suspension effect thanks to the hierarchy of suspension slats 31, 32, 33.
  • FIG. 3 a variant according to the invention is also illustrated in FIG. 3 and in section in FIG. 4,
  • the support elements 3 are constituted by flexible straps 53, produced by example in a fabric such as ultra-light canvas. An ultra-light embodiment is thus obtained.
  • the section of each support strap 53 is shown on the sectional view of Figure 4 in which we see also clearly that this is also in this variant of a template suspension structure completely flat, as in the variant described above.
  • FIG. 5 and 6 Yet another variant of execution is illustrated on Figures 5 and 6. This is of great interest particular since it shows the monobloc realization of all.
  • the hinge pins are replaced here by narrowed connecting zones 221 between the slats support 203 on the one hand and the elements of suspension 231, 232, 233 on the other hand. These latter 231, 232, 233 meanwhile have a reinforcement zone 230 in the form of a protruding bead. These provide sufficient rigidity to each element of which are heavily used during use of the wheelchair.
  • the entire support plate 211 can be made of a piece, for example of synthetic material, in particular by injection molding.
  • the elements of suspension 331, 332, 333 have a structure which is likely to allow them to fit together as well that it emerges from FIG. 11 and 12 respectively for the backrest 311 and for the seat 312 of an armchair.
  • support elements in form of slats 303 shown in dotted lines for the convenience of representation which are each fixed by a double articulation link 320, 320 and in pairs to a primary link 331 having for example a T shape and bringing together each time a pair of mutually adjacent slats, 303, 303.
  • the connecting elements 331 T-shaped primaries are joined in pairs to a secondary link and suspension element 332 advantageously having an H shape in which come to fit the two primary elements in shape of T 331 at respectively opposite sides of the element corresponding secondary 332.
  • the elements H-shaped secondaries are connected to an element tertiary 333 in the form of a box joining the two sub-assemblies with the above structure H-shaped elements 332 surrounded on either side 331 T-shaped elements.
  • this variant again the link structure two by two at hierarchical levels.
  • each connections between elements of successive levels 331-332, 332-333, is achieved by links hinge 321, 322, and 323 respectively.
  • Figure 12 shows the layout simpler seat 312 for this variant.
  • FIG. 10 A more detailed representation of this variant of execution in arched position of the file is represented in figure 10.
  • This figure represents a side view with partial cutaway of file 311 in arched position in which we can clearly see the interlocking cooperation between intermediate parts primary linkage and suspension 331 on the one hand and the corresponding secondary parts 332. It appears moreover clearly that the tertiary element 333 forming a box constitutes a protection of the suspension of the device according to the invention.
  • Figure 28 shows the arrangement of three dishes of support 411, 412, 413 together forming a relax 400 with multi-level suspension similar in shape to that described for the other alternative embodiments above. Performing a relax in a single support dish is illustrated in figure 27.
  • the chassis can also be made adjustable, especially in the case of relax 400.
  • the support dish as described above is also adaptable to pre-existing furniture such as a car or truck seat and like.
  • the articulation points form a connection between two elements or parts, allowing these elements to move relative to each other about an axis, which is fixed with respect to said elements or when it is necessary, which is movable.
  • An articulation point can also consist of several joints which are mounted one next to the other. They can be made from metal, hardened plastics or even a material flexible (see Figures 10, 22-23).
  • the pressure in this case starts from of a single point of articulation, and it is distributed evenly along the entire length of the wiping strip by articulated levers, which shows the analogy with a vehicle wiper, as shown in the Figures 20 and 21.
  • the user can therefore change continuously attitude while seated while back and face remain supported uniformly throughout. Any attitude or movement is therefore not a burden for the back muscles.
  • the shape of the backrest adapts continuously to that of the back.
  • the body sways on only two points of joints 323 ', 324. Even when we find our practically immobile, we must consider that we are despite everything in motion, even a tiny one little.
  • the backrest and seat can tilt together.
  • you find yourself in a tilted back position we find the attitude as in a lounge chair or relax, and in the upright position as in a seat office.
  • many activities must be provided for the seated user because the office activities are multiple, including a writing position, computer activity, telephone, each impose on the user attitudes respectively different for the back.
  • the backrest takes perfectly the corresponding shape of the back according to the needs of the moment and gives it full support. We can thus find in upright position while having a back relaxed and supple even after a seated posture extended.
  • the suspension is carried out by means of the points which are connected to the chassis.
  • means of recall suitable are advantageously provided according to the invention allowing support plates and / or parts suspension intermediaries to end up in the desired pull or push position, such as represented in figures 35 to 38 by the arrows of different amplitudes for the last two showing a suspension system in the box S, S ', these not being provided in the seats according to fig. 35-36 (uniform amplitude).
  • the number of joints and intermediate parts of suspension depends directly on the number of slats whose support plate is formed, and the desired mobility. Combinations can be made more complex and / or simpler than those illustrated in the figures depending on the desired mobility parameters support slats.
  • each support plate 511, 512 is made mobile by another type of suspension means.
  • each support plate is still made up a series of slats 503 which are interconnected by hinged links 520.
  • Each slat 503 is fixed to one, two or more double casters 581 (two double in the illustrated example), on which suspension cables 584, 585 without deflecting.
  • the casters double 581 can rotate independently one of the other. If applicable, the left and right casters can rotate integrally on an axis of rotation common 599.
  • the support plate 511 is stretched between two cables 584, 585, which are attached to the end of the chassis and make a zigzag course on the casters 581 corresponding to the slats and fixed by element 587 to these 503 and by the casters 582 which are fixed to the chassis 590.
  • One of the cables 584 receives the force which is exerted on the support plate while the other 585 cable pulls on the support plate against the chassis.
  • Each cable can be stretched by a reminder such as spring 586, which moderates the variation of length.
  • this can be attached at the top to a movable hinge. Stops can be arranged on the chassis which prevent a slat to move in an unwanted direction.
  • the dish of support can be forced to a straight state by means of a stretched cable or batten or frame that is pushed in underneath against the support plate.
  • a frame can be hinged to the underbody.
  • the slat system having substantially the same width works flawlessly for support of body parts individually such as the back, the seat, the legs, which exercise on substantially their entire length practically the same pressure on the support plate.
  • the articulation points which support the slats and the intermediate pieces are moved towards the location where the highest pressure. So we shorten the arm from the moment where the pressure increases.
  • the device according to the invention can support directly to the body or require only a very thin coating layer.
  • a spring or a counterweight so to prevent the file from collapsing. It is however also possible to hang on each side of the mechanism a series of slats in order to get this same effect.
  • Each slat serves as a counterweight for the slat which is mounted on the other side.
  • support elements 603 can be provided such that the slats in direct connection with each other by hinges as described above or else can also be arranged with free rotation around of a longitudinal axis of rotation by providing in this case a small gap 640 between support elements mutually adjacent.
  • elements of support in the form of slats these must then be pulled in the right direction by means of a bond flexible 600.
  • small rollers 703 which are preferably made of a material compressible, these can then rotate completely around their axis 713.
  • the rounded shape of the support elements 703 can exert an action stimulating on the parts of the body in contact with them providing a pleasant effect.
  • pleasant ventilation is also induced on the body part in support.
  • suspension system or mechanism implemented can be arranged as well in underside of the hanging support plate with in this case a labile balance, see in particular Figures 9 to 16, that laterally, i.e. on the side of the slats of support proper with in this case a balance neutral as described above (see figures 1 to 8), thus that an arrangement above the support plate generating in this case a stable equilibrium situation, (see figure 32) and each time of course in one or more assembly plans.

  • Means of support are also made mutually interdependent as in the variants described above with the connections of hierarchical articulations illustrated in the figures 30 and 31 which are arranged analogously to execution variants described above.
  • An 811 support dish of this type is especially suitable in the case of a bed allowing relaxation in all directions.
  • FIG. 34 Another variant not forming part of the invention is illustrated in FIG. 34. It represents a 911 support dish arranged as buffer interface between the back 901 of a schoolboy 1 and a satchel or any baggage 950, in particular in hardened synthetic.
  • a means of interface with the back which must carry it becomes practically essential if we want to avoid the evils of back, especially for children still in full growth.
  • a good distribution of the pressure of the satchel which can be loaded inside in a strong way uneven is very useful and helps effectively to avoid the appearance in particular of scoliosis.
