Description

La présente invention concerne un agencement d'assise de siège, réglable, notamment pour personnes âgées.The present invention relates to a seating arrangement, adjustable, especially for the elderly.

Les sièges utilisés notamment pour être assis devant une table comprennent des pieds, une assise et un dossier.The seats used in particular for sitting in front of a table include feet, a seat and a backrest.

L'angle entre l'assise et le dossier contribue en grande partie au confort de l'utilisateur, il est étudié et doit donc être conservé.The angle between the seat and the backrest largely contributes to the comfort of the user, it is studied and must be preserved.

On connaît des sièges plus utilisés dans les bureaux d'une grande complexité, avec des dossiers réglables voire mobile mais ces agencements sont éloignés de la présente invention. Les sièges concernés sont des sièges à assise fixe, notamment utilisés pour les personnes âgées en maisons médicalisée ou de retraite mais qui pourraient aussi être utilisés en famille.There are known seats more used in offices of great complexity, with adjustable folders or mobile but these arrangements are far from the present invention. The seats concerned are fixed-seat seats, particularly used for elderly people in nursing homes or retirement homes but which could also be used as a family.

L'assise est généralement rapportée sur un cadre lui-même supporté par les pieds, cette assise étant fixée sur le cadre de façon non mobile.The seat is generally attached to a frame itself supported by the feet, this seat being fixed to the frame in a non-movable manner.

On constate que les utilisateurs de tels sièges ont des tailles différentes et actuellement les sièges, notamment en collectivité sont tous identiques.It is noted that the users of such seats have different sizes and currently the seats, including community are all identical.

En effet, quelle que soit la taille de la personne ou sa morphologie, les sièges sont identiques.Indeed, whatever the size of the person or his morphology, the seats are identical.

Il a donc été étudié des sièges qui ont une hauteur d'assise moyenne, ce qui correspond généralement à une majorité de personnes mais pas à celles qui sont un peu en dessus de la moyenne retenue ou un peu en dessous de cette moyenne.Therefore, seats with an average seat height have been studied, which generally corresponds to a majority of people but not to those that are a little above or below the average.

On constate donc que les personnes qui sont de plus petite taille que la moyenne ont les pieds qui ne reposent pas au sol lorsqu'elles sont assises. La solution bien sûr consiste à s'avancer sur l'assise pour que les pieds reposent au sol.As a result, people who are smaller than average have feet that do not sit on the floor when sitting. The solution of course is to step on the seat so that the feet rest on the ground.

Deux inconvénients à cette solution :

  • Le dossier n'a plus aucun rôle,
  • L'utilisateur n'a qu'une petite longueur de cuisse reposant sur l'assise, ce qui est peu confortable d'une part et peut couper ou du moins limiter la circulation du sang dans lesdites cuisses. Les cuisses ne sont pas horizontales du fait d'une longueur de pied/tibia/genou inférieure à la hauteur d'assise. Les cuisses sont inclinées vers le bas.
Two disadvantages to this solution:
  • The folder no longer has any role,
  • The user has only a small length of thigh resting on the seat, which is uncomfortable on the one hand and can cut or at least limit the flow of blood in said thighs. The thighs are not horizontal due to a length of foot / shin / knee lower than the sitting height. The thighs are tilted down.

Ces phénomènes sont généralement aggravés par un état physique dégradé de la personne donc ces phénomènes sont plus sensibles pour des personnes âgées.These phenomena are generally aggravated by a degraded physical state of the person so these phenomena are more sensitive for elderly people.

Quant aux personnes de grande taille, elles ont beau se caler au fond du siège, elles ont les pieds qui reposent au sol cette fois, mais les cuisses se trouvent soulevées de l'assise, inclinées vers le haut, conduisant à des sensations d'inconfort là aussi. Le poids repose sur le sacrum et crée là aussi des points de compression, sans compter les éventuelles cyphose et lordose déviante à terme du fait de la faiblesse de la colonne liée à l'âge.As for tall people, they can sit at the bottom of the seat, they have their feet resting on the ground this time, but the thighs are raised from the seat, inclined upwards, leading to sensations of discomfort there too. The weight rests on the sacrum and creates there also points of compression, not counting the possible kyphosis and devastating lordosis at term because of the weakness of the column related to the age.

Il y a donc besoin d'un agencement d'assise réglable pour répondre à de telles demandes d'ajustement en hauteur car il n'est pas envisageable de pouvoir disposer d'un parc de chaises en nombre suffisant pour répondre à la demande des utilisateurs, nombre qui, en collectivités, est variable.There is therefore a need for an adjustable seating arrangement to meet such requests for height adjustment because it is not possible to have a sufficient number of chairs to meet the users' demand. , which in communities is variable.

Or, les variations sont limitées entre le minimum et le maximum requis, quelques centimètres seulement mais cette faible variation conditionne le confort ou l'inconfort de la très grande majorité des personnes.However, the variations are limited between the minimum and the maximum required, only a few centimeters, but this small variation conditions the comfort or discomfort of the vast majority of people.

On comprend que, néanmoins, la situation et les applications sont soumises à de nombreuses contraintes.It is understood that, nevertheless, the situation and applications are subject to many constraints.

Ces sièges, utilisés notamment en collectivités, doivent rester de l'ameublement en accord avec le style du lieu et non du mobilier médical, les mécanismes apparents sont donc proscrits.These seats, used especially in communities, must remain furniture in accordance with the style of the place and not the medical furniture, the apparent mechanisms are therefore prohibited.

Le coût de ces mobiliers doit être limité car les chaises s'inscrivent dans un ensemble de meubles et sont vendues avec les autres meubles, les chaises ne peuvent donc pas représenter un coût disproportionné de ces ensembles.The cost of such furniture must be limited because the chairs are part of a set of furniture and are sold with other furniture, chairs can not therefore represent a disproportionate cost of these sets.

De telles chaises ne peuvent comporter des mécanismes nécessitant des outils de réglage, qui pourraient engendrer des manipulations de réglage complexes et encore moins des mouvements qui pourraient occasionner des blessures.Such chairs can not include mechanisms requiring adjustment tools, which could lead to complex adjustment manipulations and even less movements that could cause injury.

Il convient de laisser aussi les moyens de réglage aussi discrets que possible afin de ne pas donner prise à de quelconques remarques sur la position plus ou moins haute de l'assise.It is also advisable to leave the adjustment means as discrete as possible so as not to make any comments on the higher or lower position of the seat.

Le temps de réglage doit aussi être d'une rapidité certaine car le moment venu, lors des repas par exemple, il faut que le personnel éventuellement mis à contribution puisse ajuster la hauteur de façon rapide, les occupations à ce moment-là étant multiples.The adjustment time must also be of a certain speed because when the time comes, during meals for example, it is necessary that the staff possibly involved can adjust the height quickly, the occupations at that time being multiple.

La présente invention propose un agencement simple à réaliser, qui pallie les inconvénients des chaises ci-avant décrites et qui répond aux contraintes imposées par l'application. L'agencement selon la présente invention est maintenant décrit en regard des dessins annexés, dessins comportant des figures qui représentent :

  • Figure 1 : une vue en perspective d'une chaise selon la présente invention dans la première position, basse,
  • Figure 2 : une vue en perspective d'une chaise selon la présente invention dans la seconde position, haute,
  • Figure 3 : une vue du montant latéral du cadre et du support d'assise selon l'agencement de l'invention, montrant les pistes,
  • Figures 4A à 4E : une vue du synoptique de fonctionnement et de réglage de l'assise.
The present invention provides a simple arrangement to achieve, which overcomes the disadvantages of the chairs described above and which meets the constraints imposed by the application. The arrangement according to the present invention is now described with reference to the accompanying drawings, drawings comprising figures which represent:
  • Figure 1 : a perspective view of a chair according to the present invention in the first position, low,
  • Figure 2 : a perspective view of a chair according to the present invention in the second position, high,
  • Figure 3 : a view of the lateral amount of the frame and the seat support according to the arrangement of the invention, showing the tracks,
  • Figures 4A to 4E : a view of the synoptic of operation and adjustment of the seat.

Sur les figures 1 et 2, on a représenté une chaise 10 selon la présente invention qui comprend un cadre 12 destiné à recevoir une assise 14, quatre pieds se prolongeant dudit cadre vers le sol et un dossier 16 se prolongeant dudit cadre dans la direction opposée.On the Figures 1 and 2 , there is shown a chair 10 according to the present invention which comprises a frame 12 for receiving a seat 14, four feet extending from said frame to the ground and a backrest 16 extending from said frame in the opposite direction.

Les deux pieds arrière et le dossier peuvent être monolithiques pour ces chaises, ceci n'étant qu'une option constructive, ces options ne faisant pas partie de la présente invention. L'assise 14 et le dossier 16 présentent un angle d'inclinaison ouvert, par exemple 95° pour donner un ordre de grandeur pour une chaise destinée à être utilisée à table.The two back legs and the backrest can be monolithic for these chairs, this being only a constructive option, these options not being part of the present invention. The seat 14 and the backrest 16 have an open angle of inclination, for example 95 ° to give an order of magnitude for a chair for use at the table.

L'assise 14 est un support 18 d'assise, généralement de forme ergonomique, comportant un léger creux en partie centrale, recouvert d'un revêtement de toute nature, tissu, bois ou matière plastique, avec interposition ou non d'une matière de confort telle qu'une mousse.The seat 14 is a seat support 18, generally ergonomically shaped, having a slight hollow in the central part, covered with a coating of any kind, fabric, wood or plastic, with or without interposition of a material of comfort such as a foam.

Ce support 18 d'assise, selon la présente invention, comprend au moins deux traverses 20-1 et 20-2, orientées transversalement, c'est-à-dire parallèlement au dossier.This seat support 18, according to the present invention, comprises at least two cross members 20-1 and 20-2, oriented transversely, that is to say parallel to the folder.

Ces deux traverses sont munies, à chacune de leurs extrémités, d'un tourillon 22. Le terme "tourillon" est pris dans son acceptation la plus large d'axe, et s'applique à tout type de matériau. Ces tourillons peuvent être venus de fabrication avec lesdites traverses, notamment quand ces traverses sont réalisées en bois.These two crosspieces are provided at each of their ends with a pin 22. The term "pin" is taken in its widest acceptance axis, and applies to any type of material. These pins may have come from manufacture with said sleepers, especially when these sleepers are made of wood.

Le cadre 12 comporte des montants latéraux, droit 24R et gauche 24L, si l'on considère une vue de l'utilisateur assis.The frame 12 has side uprights, right 24R and left 24L, if we consider a view of the seated user.

Ces montants latéraux 24R et 24L comportent chacun deux pistes avant 26F et arrière 26R, soit quatre pistes destinées à recevoir chacune un des tourillons.These lateral uprights 24R and 24L each comprise two tracks 26F front and rear 26R, four tracks for each receive one of the pins.

Les pistes avant ont une forme générale en U renversé pour la piste 26F avant et une forme générale en V très ouvert, dont une des branches est horizontale, comme cela est visible sur la figure 3, pour la piste 26R.The front tracks have a general inverted U shape for the front runway 26F and a very open V shape, one of whose branches is horizontal, as can be seen on the figure 3 , for runway 26R.

Sur cette figure 3, on a représenté le montant 24R. La piste 26F avant comprend une branche 28 horizontale du U renversé, dont l'extrémité avant débouche dans la première branche 30 verticale, courte d'une hauteur h.On this figure 3 the amount 24R is shown. The front track 26F comprises a horizontal branch 28 of the inverted U , the front end of which opens into the first vertical branch 30, short of a height h .

La seconde branche 32 verticale du U renversé est donc verticale, longue, d'une hauteur H, la différence H - h étant égale à D, le différentiel de hauteur entre la position haute et la position basse de l'assise.The second vertical branch 32 of the inverted U is vertical, long, a height H , the difference H - h being equal to D, the height differential between the high position and the low position of the seat.

La piste arrière 26R, proche du dossier, en V ouvert, comprend une première branche 34 horizontale alignée avec le bas de l'extrémité inférieure de la première branche 30 verticale, courte d'une hauteur h. La ligne XX' passant par les centres C1, C2 est horizontale.The rear track 26R, close to the backrest, open V , comprises a first horizontal branch 34 aligned with the bottom of the lower end of the first vertical leg 30, short of a height h . The line XX 'passing through the centers C1, C2 is horizontal.

La seconde branche 36 arrière, du V ouvert, est inclinée et son extrémité est alignée avec l'extrémité de la seconde branche 32 verticale du U renversé, verticale, longue, suivant la ligne YY'.The second rear branch 36, of the open V , is inclined and its end is aligned with the end of the second vertical branch 32 of the u vertical, long U , along the line YY '.

La distance T de translation horizontale minimale est égale à la distance qui sépare les deux branches de la piste 26F avant, en U renversé.The distance T of minimum horizontal translation is equal to the distance between the two branches of the track 26F before, in U reversed.

C'est cette distance T qui correspond au recul simultané au réglage en hauteur de l'assise.It is this distance T which corresponds to the simultaneous recoil at the height adjustment of the seat.

En se reportant au synoptique de la figure 4, on retrouve à l'étape A, la position haute des tourillons 22 suivant l'axe XX'. Les traverses 20-1 et 20-2 donc en position haute, la coque 18 solidaire des traverses est aussi en position haute et l'assise 14 est de fait en position haute. On note aussi que l'assise 14 se trouve en position vers l'avant.Referring to the synoptic of the figure 4 , found in step A, the upper position of the journals 22 along the axis XX '. The sleepers 20-1 and 20-2 therefore in the high position, the shell 18 secured to the sleepers is also in the high position and the seat 14 is actually in the high position. It is also noted that the seat 14 is in the forward position.

A l'étape B, l'opérateur soulève l'avant de l'assise, si bien que le tourillon 22 de la traverse 20-1 est soulevé le long de la première branche 30, courte, tandis que le tourillon 22 de la traverse 20-2 reste en place.In step B, the operator raises the front of the seat, so that the trunnion 22 of the crossbar 20-1 is lifted along the first leg 30, short, while the trunnion 22 of the transom 20-2 stays in place.

A l'étape C, l'opérateur assure une translation vers l'arrière de l'assise et, cette fois, ce sont les deux tourillons qui sont entraînés vers l'arrière dans la partie horizontale de la piste 26F et dans la partie inclinée de la piste 26R.In step C, the operator provides a rearward translation of the seat and, this time, it is the two journals that are driven backwards in the horizontal portion of the track 26F and in the inclined portion from runway 26R.

A l'étape D, les tourillons 22 des traverses 20-1 et 20-2 sont en butée dans la branche 28 horizontale de la piste 26F et au fond de la seconde branche 36 de la piste 26R.In step D, the journals 22 of the cross members 20-1 and 20-2 abut in the horizontal branch 28 of the track 26F and at the bottom of the second branch 36 of the track 26R.

Il suffit ensuite pour l'opérateur d'abaisser l'assise pour conduire le tourillon 22 de la traverse avant 20-1 au fond de la seconde branche 32 longue du U renversé, voir étape E.It is then sufficient for the operator to lower the seat to drive the trunnion 22 of the front cross member 20-1 to the bottom of the second branch 32 long U reversed, see step E.

On est donc passé d'une assise vers l'avant et haute pour le confort de personnes de tailles plus grandes que la moyenne jusqu'aux personnes de tailles moyennes à une position en arrière et basse pour le confort des personnes de tailles inférieures à la moyenne et pour les personnes de tailles moyennes aussi.So we have moved from a forward and a high seat for the comfort of people of sizes larger than average to medium-sized people at a back and low position for the comfort of people of sizes below medium and for medium-sized people too.

Le dispositif répond aux problématiques posées de simplicité de réalisation, de simplicité de mise en oeuvre, de coût de fabrication limité, de suppression de tout risque de blessure, de confort de tous les usagers avec un réglage simultané hauteur et avance de l'assise.The device addresses the issues raised simplicity of implementation, simplicity of implementation, limited manufacturing cost, removal of any risk of injury, comfort of all users with a simultaneous height adjustment and advance of the seat.

Le mode de réalisation qui a été présenté comporte des pistes en creux sur les montants et des tourillons en saillie sur les traverses mais sur d'autres agencements strictement similaires les tourillons peuvent être portés par les montants et les pistes par l'assise.The embodiment that has been presented includes recessed tracks on the uprights and pins projecting from the rails but on other strictly similar arrangements the pins can be carried by the uprights and tracks by the seat.

De même, la présentation vise des applications avec des chaises généralement en bois pour les applications visées mais dans le cas du recours à des matières plastiques ou au métal, il est possible de positionner des pistes en saillie et des tourillons sous forme de galets sans changer aucunement la présente invention.Similarly, the presentation targets applications with chairs usually made of wood for the intended applications but in the case of the use of plastics or metal, it is possible to position projecting tracks and pins in the form of pebbles without changing not the present invention.
