Definitions
- the present invention relates to a mechanism for an item of furniture, such as a seat, armchair with variable positions.
- the invention applies to seats whose relative inclination between the seat, the backrest and the various associated elements, can be modified. These modifications allow the user to obtain a multiplicity of intermediate positions between two extreme positions intended to improve comfort. These different positions are obtained by simple movement of the body of the user independently of any lever actuation or other operating handle.
- Such devices exist in the form of a fixed frame with a movable seat connected to a also movable backrest having a complement in the form of a headrest. It turns out that in the first position where the seat is completely back, the user is in the normal sitting position and the angle between the backrest and the seat is close to 90 °. The headrest is then generally retracted since the user is in the active position. In cases where the user wishes to adopt a more relaxing position, he moves by the effect of a movement of his body, the seat forward which inclines the backrest so that the angle between the same backrest and the seat is greater than 90 °, while simultaneously the headrest follows on from this backrest. There remains an ergonomic problem since the user is in a semi-recumbent position and is held only by the upper back and in the lower part by pressing on the seat, but that he has no support in the kidneys.
- the object of the present invention is therefore to overcome this drawback and to propose an operating device for a seat, armchair or sofa comprising a movable seat as well as a reclining backrest connected to this movable seat supplemented by a retractable headrest, characterized in that that it includes a retractable "lumbar support".
- the invention is more particularly characterized in that this "lumbar support" is in the retracted position when the device is used in the seated position the angle between the backrest and the seat being close to 90 ° and that it becomes place gradually when the user takes a position close to the extreme advanced position, that is to say relaxing.
- the backrest is tilted and the headrest raised.
- This device is further characterized in that this retractable "lumbar support” is a flap pivoting about a horizontal axis situated in the plane of the backrest and that the means of positioning consists of a fixed support linked to the movable seat and provided at its end with a rotating roller type support.
- the seat 1 has a structure 2 fixed and rigid made from generally metallic tubes and of adequate round or square section.
- This structure comprises a substantially vertical upright 20, a horizontal upright 21 intended to serve as a support for the entire structure on the ground and another substantially vertical upright 22 located at the other end of the upright 21 so that these three uprights form a U.
- the spacer 23 parallel to the horizontal upright 21 aims to partially stiffen the structure by connecting the vertical uprights 20 and 22.
- the spacers 24 and 25 are intended to stiffen the structure by connecting together the rear vertical uprights and the front vertical uprights respectively in order to constitute a rigid frame on which all the mobile articulation will adapt.
- the movable articulation essentially comprises a movable seat 3 as well as a movable back 4 connected to this same seat by an axis 30 making it possible to vary the angle between the seat and the back.
- This seat and backrest assembly is mounted in pivoting support on the structure 2 by means of an extension 40 pivoting on the horizontal upright 21 at 41.
- the front part of the seat 3, opposite the axis 30, can be move in support on at least one roller 31 secured to the vertical upright before 22.
- connection plate 5 The upper end of the backrest 4 opposite the axis 30 is linked to a connection plate 5 via the axis 42.
- This connection plate 5 is also mounted articulated at 50 on the vertical upright 20, this plate being mounted parallel to the plane defined by the three uprights 20, 21 and 22.
- the headrest 6 is also pivotally mounted on an axis 60 supported by this same plate 5.
- This headrest 6 has at its rear part a lever 61 fixed substantially perpendicular to the plane of the headrest and in an off-center location relative to the axis 60.
- the end of this lever 61 is also provided with a pivot axis 62 on which is mounted a connecting rod 7 of which l 'other end is connected via the axis 70 to a second lever 8 mounted perpendicular and integral with the extension 40.
- the extension 40, the lever 8, the connecting rod 7, the lever 61, the headrest 6, the connecting plate 5 and the backrest 4 thus form a deformable polygon.
- a return spring 9 fixed by one of its ends to the vertical upright 20 of the fixed structure 2 is fixed at its other end to the axis 62.
- the "kidney block” proper consists of a flap 10, of curved shape intended to adapt to the morphology of the individuals and to provide satisfactory ergonomics, pivotally mounted on a horizontal axis 11 contained in the plane of the backrest 4
- the seat 3 has at its rear end at least one fixed support 32 at the end of which is placed at least one roller 33 so that the flap 10 of the "kidney block” is supported on this roller and that it can roll on its underside.
- the extension 40 pulled forward therefore completely changes the orientation of the lever 8 which performs a movement along an ellipsoidal curve indicated by the arrow 80 and simultaneously moves up the rod 7 which in turn changes the orientation of the lever 61 according to arrow 63 to bring it into a quasi-horizontal position which then places the headrest 6 in a slightly inclined rearward position since the lever 61 and the headrest 6 are perpendicular.
- the spring 9 is then in a tensioned return position.
- the roller 33 has therefore made a displacement identical to that of the seat 3 while the axis 11 has slightly descended having not carried out a displacement as large as that of the seat since this axis (11) is located near the pivot axis of the backrest 4. It will then be understood that the flap 10 is in a position further away from the backrest 4 according to arrow 12 and by the same is then able to fill the space left free by the user in a relaxed position thus playing a supporting role, a function necessary for the comfort of the user in this position.
- the seat can be supplemented by armrests which are integral with it and that the headrest can be actuated in a different way without thereby departing from the scope of the invention.
- the return spring brings it back to the seated position via the return spring, but it is understood that the reverse could be achieved by connecting the rear end of the seat 3 directly to the vertical upright 20 by means of a spring.

Description
La présente invention a pour objet un mécanisme pour un article de mobilier, tel qu'un siège, fauteuil à positions variables.The present invention relates to a mechanism for an item of furniture, such as a seat, armchair with variable positions.
Plus particulièrement, l'invention s'applique aux sièges dont l'inclinaison relative entre l'assise, le dossier et les différents éléments associés, est modifiable. Ces modifications permettent à l'utilisateur d'obtenir une multiplicité de positions intermédiaires entre deux positions extrêmes destinées à améliorer le confort. Ces différentes positions sont obtenues par simple mouvement du corps de l'utilisateur indépendamment de tout actionnement de levier ou autre poignée de manoeuvre.More particularly, the invention applies to seats whose relative inclination between the seat, the backrest and the various associated elements, can be modified. These modifications allow the user to obtain a multiplicity of intermediate positions between two extreme positions intended to improve comfort. These different positions are obtained by simple movement of the body of the user independently of any lever actuation or other operating handle.
De tels dispositifs existent sous la forme d'un bâti fixe avec une assise mobile reliée à un dossier également mobile disposant d'un complément sous la forme d'un appuitête. Il se trouve que dans la position première où l'assise est totalement reculée , l'utilisateur se trouve en position assise normale et l'angle entre le dossier et l'assise est voisin de 90°. L'appui-tête est alors généralement escamoté puisque l'utilisateur est en position active. Dans les cas où l'utilisateur souhaite adopter une position plus relaxante, il déplace par l'effet d'un mouvement de son corps, l'assise vers l'avant ce qui incline le dossier de façon que l'angle entre ce même dossier et l'assise soit supérieur à 90°, tandis que simultanément l'appui-tête vient dans le prolongement de ce dossier. Il subsiste alors un problème ergonomique puisque l'utilisateur est en position semi-allongée et qu'il n'est tenu que par le haut du dos et en partie inférieure par appui sur l'assise, mais qu'il n'a aucun maintien au niveau des reins.Such devices exist in the form of a fixed frame with a movable seat connected to a also movable backrest having a complement in the form of a headrest. It turns out that in the first position where the seat is completely back, the user is in the normal sitting position and the angle between the backrest and the seat is close to 90 °. The headrest is then generally retracted since the user is in the active position. In cases where the user wishes to adopt a more relaxing position, he moves by the effect of a movement of his body, the seat forward which inclines the backrest so that the angle between the same backrest and the seat is greater than 90 °, while simultaneously the headrest follows on from this backrest. There remains an ergonomic problem since the user is in a semi-recumbent position and is held only by the upper back and in the lower part by pressing on the seat, but that he has no support in the kidneys.
La présente invention a donc pour objet de pallier cet inconvénient et de proposer un dispositif de manoeuvre pour siège, fauteuil ou canapé comportant une assise mobile ainsi qu'un dossier inclinable relié à cette assise mobile complété par un appui-tête escamotable, caractérisé en ce qu'il comporte un "cale-reins" escamotable. L'invention est plus particulièrement caractérisée en ce que ce "cale-reins" est en position escamotée lorsque le dispositif est utilisé en position assise l'angle entre le dossier et l'assise étant voisin de 90° et qu'il se met en place progressivement lorsque l'utilisateur prend une position proche de la position extrême avancée, c'est-à-dire relaxante. Le dossier est incliné et l'appui-tête relevé. Ce dispositif est encore caractérisé en ce que ce "cale-reins" escamotable est un volet pivotant autour d'un axe horizontal situé dans le plan du dossier et que le moyen de mise en place est constitué d'un support fixe lié à l'assise mobile et muni à son extrémité d'un appui tournant du type galet.The object of the present invention is therefore to overcome this drawback and to propose an operating device for a seat, armchair or sofa comprising a movable seat as well as a reclining backrest connected to this movable seat supplemented by a retractable headrest, characterized in that that it includes a retractable "lumbar support". The invention is more particularly characterized in that this "lumbar support" is in the retracted position when the device is used in the seated position the angle between the backrest and the seat being close to 90 ° and that it becomes place gradually when the user takes a position close to the extreme advanced position, that is to say relaxing. The backrest is tilted and the headrest raised. This device is further characterized in that this retractable "lumbar support" is a flap pivoting about a horizontal axis situated in the plane of the backrest and that the means of positioning consists of a fixed support linked to the movable seat and provided at its end with a rotating roller type support.
D'autres avantages et détails apparaîtront à la lecture de la description d'un mode de réalisation particulier non limitatif en relation avec les figures annexées qui représentent :
- Figure 1 : dispositif selon l'invention vue en coupe dans ses deux positions extrêmes.
- Figure 2 : vue en perspective de la cale de reins selon l'invention.
- Figure 1: device according to the invention seen in section in its two extreme positions.
- Figure 2: perspective view of the kidney block according to the invention.
Le siège 1 selon l'invention comporte une structure 2 fixe et rigide réalisée à partir de tubes généralement métalliques et de section adéquate ronde ou carrée.Cette structure comporte un montant sensiblement vertical 20, un montant horizontal 21 destiné à servir d'appui à l'ensemble de la structure sur le sol et une autre montant sensiblement vertical 22 situé à l'autre extrémité du montant 21 de façon à ce que ces trois montants forment un U. L'entretoise 23 parallèle au montant horizontal 21 a pour but de rigidifier en partie la structure en reliant les montants verticaux 20 et 22. De même, les entretoises 24 et 25 ont pour but de rigidifier la structure en reliant entre eux respectivement les montants verticaux arrière et les montants verticaux avant afin de constituer un cadre rigide sur lequel viendra s'adapter toute l'articulation mobile.The
L'articulation mobile comporte essentiellement une assise mobile 3 ainsi que d'un dossier mobile 4 relié à cette même assise par un axe 30 permettant de faire varier l'angle entre l'assise et le dossier. Cet ensemble assise et dossier est monté en appui pivotant sur la structure 2 par l'intermédiaire d'une prolongation 40 pivotant sur le montant horizontal 21 en 41. La partie avant de l'assise 3, opposée à l'axe 30, peut se déplacer en appui sur au moins un galet 31 solidaire du montant vertical avant 22.The movable articulation essentially comprises a
L'extrémité supérieure du dossier 4 opposée à l'axe 30 est liée à une plaque de liaison 5 par l'intermédiaire de l'axe 42. Cette plaque de liaison 5 est également montée articulée en 50 sur le montant vertical 20, cette plaque étant montée parallèle au plan défini par les trois montants 20, 21 et 22. L'appui-tête 6 est également monté pivotant sur un axe 60 supporté par cette même plaque 5. Cet appui-tête 6 comporte à sa partie arrière un levier 61 fixe sensiblement perpendiculaire au plan de l'appui-tête et en un endroit décentré par rapport à l'axe 60. L'extrémité de ce levier 61 est munie également d'un axe de pivotement 62 sur lequel est montée une bielle 7 dont l'autre extrémité est reliée par l'intermédiaire de l'axe 70 à un deuxième levier 8 monté perpendiculaire et solidaire de la prolongation 40. La prolongation 40, le levier 8, la bielle 7, le levier 61, l'appui-tête 6, la plaque de liaison 5 et le dossier 4 forment ainsi un polygone déformable. Un ressort de rappel 9 fixé par une de ses extrémités au montant vertical 20 de la structure fixe 2 est fixé à son autre extrémité à l'axe 62.The upper end of the
Le "cale-reins" proprement dit est constitué d'un volet 10, de forme courbe destinée à s'adapter à la morphologie des individus et à procurer une ergonomie satisfaisante, monté pivotant sur un axe 11 horizontal contenu dans le plan du dossier 4. D'autre part, l'assise 3 comporte à son extrémité arrière au moins un support fixe 32 à l'extrémité duquel est placé au moins un galet 33 de façon que le volet 10 du "cale-reins" prenne appui sur ce galet et que celui-ci puisse rouler sur sa face inférieure.The "kidney block" proper consists of a
On a représenté en traits pointillés la position que prend le dispositif lors du déplacement vers l'avant de l'assise 3, sous l'effet de la variation de position du corps de l'utilisateur. Simultanément, l'axe 30, entraîne vers l'avant l'extrémité inférieure du dossier 4 ainsi que l'extrémité supérieure de la prolongation 40. Ce même dossier 4 étant monté pivotant par l'axe 42 sur la plaque 5, prend donc une position inclinée vers l'arrière, l'angle entre le dossier et l'assise devenant supérieure à 90°. La prolongation 40 tirée vers l'avant change donc totalement l'orientation du levier 8 qui effectue un mouvement suivant une courbe ellipsoïdale indiquée par la flèche 80 et simultanément déplace vers le haut la bielle 7 qui à son tour change l'orientation du levier 61 selon la flèche 63 pour l'amener dans une position quasi-horizontale ce qui place alors l'appui-tête 6 dans une position légèrement inclinée vers l'arrière puisque le levier 61 et l'appui-tête 6 sont perpendiculaires. Le ressort 9 se trouve alors dans une position de rappel tendu.The position taken by the device during the forward movement of the
Simultanément, le galet 33 a donc effectué un déplacement identique à celui de l'assise 3 tandis que l'axe 11 est légèrement descendu n'ayant pas effectué un déplacement aussi important que celui de l'assise puisque cet axe (11) est situé à proximité de l'axe de pivotement du dossier 4. On comprend alors que le volet 10 se trouve dans une position plus écartée du dossier 4 suivant la flèche 12 et par la même est alors apte à combler l'espace laissé libre par l'utilisateur dans une position relaxée jouant ainsi un rôle de supportage, fonction nécessaire au confort de l'utilisateur dans cette position.Simultaneously, the
Sur la figure 2, on distingue encore plus nettement les montants latéraux 43 et 44 du dossier 4 ainsi que l'alésage permettant le passage de l'axe 42 reliant ces mêmes montants à la plaque 5 non figurée. De même, cette figure met en évidence la prolongation 40 et le levier 8 qui lui est perpendiculaire et par l'intermédiare duquel l'appui-tête peut être relevé grâce à la bielle 7 et au levier supplémentaire 61. Le volet 10 est donc monté sur un axe 11 situé dans le plan du dossier 4 et perpendiculaire aux montants 43 et 44. La forme de ce volet n'est bien évidemment donnée qu'à titre indicatif et pourra prendre toute forme adaptée que voudra bien lui donner l'homme de l'art afin de suivre au mieux le profil lombaire de l'utilisateur.In Figure 2, there are even more clearly the
On comprend aussi que l'assise peut être complétée par des accoudoirs qui en seraient solidaires et que l'appui-tête peut être actionné d'une façon différente sans pour cela sortir du cadre de l'invention.It is also understood that the seat can be supplemented by armrests which are integral with it and that the headrest can be actuated in a different way without thereby departing from the scope of the invention.
De même il est possible de prévoir des réglages sur les différents montants afin de modifier les déplacements du polygone déformable et d'adapter l'amplitude des mouvements.Similarly, it is possible to provide adjustments on the different uprights in order to modify the displacements of the deformable polygon and to adapt the amplitude of the movements.
Lorsque le fauteuil n'est pas utilisé le ressort de rappel ramène celui-ci en position assise par l'intermédiaire du ressort de rappel mais il est entendu que l'inverse pourrait être réalisé en reliant l'extrémité arrière de l'assise 3 directement au montant vertical 20 par l'intermédiaire d'un ressort.When the chair is not used, the return spring brings it back to the seated position via the return spring, but it is understood that the reverse could be achieved by connecting the rear end of the
La présent invention n'est pas limitée aux exemples de réalisation qui viennent d'étre décrits, elle est au contraire susceptible de modifications et de variantes qui apparaîtront à l'homme de l'art.The present invention is not limited to the exemplary embodiments which have just been described, it is on the contrary liable to modifications and variants which will appear to those skilled in the art.
