Description

L'invention a pour objet un dispositif d'amortissement pour dossier de siège inclinable et un dispositif de réglage d'inclinaison de l'assise, applicable dans le secteur du mobilier et plus spécifiquement le secteur du mobilier d'assise pour le secteur médical, ou paramédical.The invention relates to a damping device for reclining seat back and a tilt adjustment device of the seat, applicable in the furniture sector and more specifically the seating furniture sector for the medical sector, or paramedical.

En effet, dans un siège, en plus des efforts d'amortissement verticaux généralement repris par un amortissement placé dans le pied du siège, comme dans les mobiliers de bureau, il est souhaitable que le dossier soit également amorti et ainsi fournir un appui permanent souple sur le dos de la personne lorsqu'elle s'assoit sur le siège ou qu'elle s'en retire ou tout simplement lors des réglages.Indeed, in a seat, in addition to the vertical damping efforts generally taken up by a damping placed in the foot of the seat, as in the office furniture, it is desirable that the file is also amortized and thus provide a flexible permanent support on the person's back when sitting on or off the seat, or simply when making adjustments.

En effet, une fois la majorité du poids de l'utilisateur exercée sur l'assise, il est primordial d'amortir le mouvement arrière du dos lorsque la personne se penche en arrière et vient prendre appui sur le dossier pour l'incliner, tant en inclinaison qu'en retour d'inclinaison.Indeed, once the majority of the weight of the user exerted on the seat, it is essential to dampen the back movement of the back when the person leans back and comes to bear on the backrest to tilt, both in inclination in return of inclination.

De plus, il est également important de pouvoir disposer d'un réglage de l'inclinaison de l'assise, associé à l'inclinaison du dossier mais aussi un réglage indépendant de l'inclinaison de l'assise du siège et ce, de manière indépendante du réglage de la position et de l'amortissement du dossier.In addition, it is also important to have an adjustment of the inclination of the seat, associated with the inclination of the backrest but also an independent adjustment of the inclination of the seat cushion and this, so independent of the adjustment of the position and the damping of the backrest.

Dans le milieu médical, la qualité d'amortissement est très importante et doit permettre un amortissement souple et progressif du dos lorsque la personne s'installe et ce, quelle que soit la corpulence de la personne.In the medical community, the quality of depreciation is very important and must allow a gradual and flexible depreciation of the back when the person installs, regardless of the body size of the person.

L'amortissement des dossiers est bien connu et se trouve très souvent proposé sur les chaises et autres fauteuils mais celui-ci n'est pas réglable et ne présente pas les qualités d'amortissement, modulables et souhaitables en milieu médical et paramédical.The depreciation of the files is well known and is very often offered on chairs and other armchairs but it is not adjustable and does not have the damping qualities, flexible and desirable in medical and paramedical.

De plus, le siège est souvent uniquement lié au dossier et induit donc un réglage non dissociable de l'assise et du dossier. Il conviendrait de disposer d'un réglage aisé de l'inclinaison et de l'amortissement du dossier permettant l'adaptation de l'amortissement en fonction du souhait de chaque utilisateur. La présente invention propose un dispositif d'amortissement réglable de l'inclinaison du dossier d'un siège et d'un dispositif de positionnement de l'assise du siège.In addition, the seat is often only linked to the backrest and thus induces a non-dissociable adjustment of the seat and backrest. An easy adjustment of the inclination and damping of the backrest should be available to allow the adaptation of the damping according to the wishes of each user. The present invention provides a device adjustable damping of the inclination of the back of a seat and a device for positioning the seat cushion.

La présente invention est décrite suivant un mode de réalisation principal et de ses variantes, ceci en regard des dessins associés sur lesquels les différentes figures représentent :

  • Figure 1 : une vue en perspective de dessus de la structure de siège selon l'invention,
  • Figure 2 : une vue en perspective de dessous de la structure de siège de la figure 1,

  • Figure 4 : a right side elevation of the seat structure of the figure 1 ,
  • Figures 5A to 5F : a synopsis of the operation of the seat and its possibilities.

Sur l'ensemble des figures, seule la structure du siège est représentée. Les autres éléments formant le siège comme les pieds, le garnissage avec les mousses et les textiles et autres accessoires sont considérés comme connus et surtout sont généralement adaptés aux besoins.In all the figures, only the seat structure is shown. Other elements forming the seat such as feet, lining with foams and textiles and other accessories are considered well known and are mostly adapted to the needs.

La structure de siège est visible sur l'ensemble des figures 1 à 5 sous différents angles, figures sur lesquelles on considère pour la suite de la description un repère orthonormé X,Y,Z.The seat structure is visible on all Figures 1 to 5 from different angles, figures on which we consider for the rest of the description an orthonormal reference X, Y, Z.

X correspond à l'axe avant / arrière de l'assise, sensiblement horizontal aux inclinaisons près. Y correspond à l'axe sensiblement horizontal, perpendiculaire à X.X corresponds to the front / rear axis of the seat, substantially horizontal with inclinations close. Y corresponds to the substantially horizontal axis, perpendicular to X.

Z correspond à l'axe longitudinal du dossier, perpendiculaire au plan XY, sensiblement vertical aux inclinaisons près.Z corresponds to the longitudinal axis of the backrest, perpendicular to the XY plane, substantially vertical at near inclinations.

La structure de siège comporte des moyens d'assise 10 et un dossier 12. Les moyens d'assise 10 comportent un bâti d'assise fixe 14 et une structure d'assise réglable 16 comportant deux pattes de pivotement 16-1 et 16-2, munies de deux axes d'articulation 18. Il est considéré que l'arrière de la structure de siège est la partie comportant le dossier 12, l'avant de la structure de siège étant la face par laquelle l'utilisateur prend place.The seat structure comprises seat means 10 and a backrest 12. The seating means 10 comprise a fixed seat frame 14 and an adjustable seat structure 16 having two pivoting lugs 16-1 and 16-2. , provided with two hinge pins 18. It is considered that the rear of the seat structure is the portion with the backrest 12, the front of the seat structure being the face by which the user takes place.

Le bâti d'assise fixe 14 porte sur sa partie avant, une chape 14C.The fixed seat frame 14 carries on its front part, a yoke 14C.

Le bâti d'assise fixe 14 comprend aussi des moyens de réglage, propres, de l'inclinaison de l'assise 20, comprenant une crémaillère 22 avec des encoches, en l'occurrence une succession d'encoches hémicirculaires et une barre 24 au profil des encoches, en l'occurrence de section hémisphérique, coopérant avec les encoches de ladite crémaillère 22.The fixed seat frame 14 also comprises adjustment means, clean, the inclination of the seat 20, comprising a rack 22 with notches, in this case a succession of hemicircular notches and a bar 24 profile notches, in this case of hemispherical section cooperating with the notches of said rack 22.

La structure d'assise réglable 16 comprend un cadre, dans le cas retenu de forme sensiblement carrée, développé dans le plan X,Y et apte à recevoir les garnissages de confort tels que des coussins et autre éléments textiles, non représentés. Ce cadre est solidaire des pattes de pivotement 16-1 et 16-2.The adjustable seat structure 16 comprises a frame, in the retained case of substantially square shape, developed in the plane X, Y and adapted to receive the comfort packings such as cushions and other textile elements, not shown. This frame is integral with the pivot lugs 16-1 and 16-2.

Le bâti d'assise fixe 14 est relié à un élément articulé 26, lui-même comprenant deux éléments longitudinaux 26-1 et 26-2 articulés, entre deux de leurs extrémités, par un pivot 27 à trou oblong de façon à autoriser les variations angulaires entre lesdits deux éléments longitudinaux 26-1 et 26-2. Le trou oblong compense les variations de longueur. Cet agencement faisant partie du dispositif d'amortissement.The fixed seat frame 14 is connected to an articulated element 26, itself comprising two longitudinal members 26-1 and 26-2 articulated, between two of their ends, by a pivot 27 with an oblong hole so as to allow the variations angularly between said two longitudinal members 26-1 and 26-2. The oblong hole compensates for variations in length. This arrangement forming part of the damping device.

La liaison entre le bâti d'assise fixe 14 et l'élément articulé 26 est complété par deux axes d'articulation 28-1 et 28-2 verticaux, fixes par rapport au bâti d'assise, disposés aux deux autres extrémités des éléments longitudinaux 26-1 et 26-2, autorisant un mouvement de pivotement horizontal des deux éléments longitudinaux 26-1 et 26-2 dans un même plan.The connection between the fixed seat frame 14 and the articulated element 26 is completed by two hinge pins 28-1 and 28-2 vertical, fixed relative to the seat frame, arranged at the other two ends of the longitudinal members 26-1 and 26-2, allowing a horizontal pivoting movement of the two longitudinal members 26-1 and 26-2 in the same plane.

L'extrémité distale d'un des éléments longitudinaux, en l'occurrence l'élément longitudinal droit 26-1 est de forme triangulaire, sensiblement rectangle, de façon à générer un sommet S distant du point de pivotement vertical 28-1.The distal end of one of the longitudinal elements, in this case the right longitudinal element 26-1 is of triangular shape, substantially rectangle, so as to generate a vertex S remote from the vertical pivot point 28-1.

Le dossier 12 de la structure de siège est formé d'une surface d'appui dorsal 30 et d'un élément de liaison 32 reliant ladite surface d'appui dorsal 30 au bâti d'assise 14 par l'intermédiaire de deux axes de pivotement 33, positionnés suivant l'axe Y, parallèlement aux axes d'articulation 18.The backrest 12 of the seat structure is formed of a backrest surface 30 and a connecting element 32 connecting said backrest surface 30 to the seat frame 14 via two pivot axes. 33, positioned along the Y axis, parallel to the hinge pins 18.

L'élément de liaison 32 comporte un élément rigide 34, reprenant la forme de la partie basse de la surface d'appui dorsal 30, solidaire de deux pattes de liaison 36-1 et 36-2 pivotantes par les axes de pivotement 33 par rapport au bâti d'assise fixe 14 d'une part et recevant les axes 18 des pattes de pivotement 16-1 et 16-2 d'autre part.The connecting element 32 comprises a rigid element 34, taking the shape of the lower part of the dorsal bearing surface 30, integral with two connecting lugs 36-1 and 36-2 pivoting by the pivot axes 33 relative to each other. to the fixed base frame 14 on the one hand and receiving the axes 18 of the pivot lugs 16-1 and 16-2 on the other hand.

Les pattes de liaison 36-1 et 36-2 sont solidaires, à leurs deux autres extrémités d'une barre de contrôle 38 qui les relie. Cette barre de contrôle 38 porte trois chapes 40-1, 40-2 et 40-3.The connecting lugs 36-1 and 36-2 are secured at their other two ends to a control bar 38 which connects them. This control bar 38 carries three clevises 40-1, 40-2 and 40-3.

L'élément articulé 26 est relié à la barre de contrôle 38 par l'intermédiaire de moyens de rappel élastique R en l'occurrence des ressorts. Ces ressorts sont de plus disposés dans la partie centrale de l'élément articulé, de part et d'autre de l'axe de pivotement 27 pour générer une symétrie.The articulated element 26 is connected to the control bar 38 by means of elastic return means R in this case springs. These springs are further disposed in the central part of the articulated element, on either side of the pivot axis 27 to generate symmetry.

Une barre de réglage 42 porte, de façon fixe, deux poignées 44 placées à chaque extrémité de ladite barre de réglage 42 et trois chapes 46-1, 46-2 et 46-3 régulièrement réparties. Les chapes 46-1, 46-2, 46-3 de la barre de réglage 42 sont imbriquées par couple et sont reliées de manière pivotante aux chapes 40-1, 40-2 et 40-3 de l'élément de liaison 32 par des axes horizontaux.An adjusting bar 42 carries, fixedly, two handles 44 placed at each end of said adjusting bar 42 and three clevises 46-1, 46-2 and 46-3 regularly distributed. The clevises 46-1, 46-2, 46-3 of the adjusting bar 42 are nested by torque and are pivotally connected to the clevises 40-1, 40-2 and 40-3 of the connecting element 32 by means of horizontal axes.

De plus, un vérin 50 est interposé entre le bâti d'assise 14 et la barre de contrôle 38.In addition, a jack 50 is interposed between the seat frame 14 and the control bar 38.

Plus particulièrement le vérin 50 est interposé entre la chape centrale 40-2 de la barre de contrôle 38 et la chape 14C solidaire de l'avant du bâti d'assise fixe 14. Le corps 52 du vérin 50 est relié par l'intermédiaire d'un axe de rotation 54 s'étendant suivant l'axe Y à la chape 14C. La tige 56 du vérin 50 est, quant à elle, reliée à la chape centrale 46-2 et comporte une languette, non représentée, qui appuie sur la tige du vérin 56 muni d'une commande pour autoriser un contrôle de positionnement de la tige du vérin par rapport au corps. Ainsi on obtient une position dans laquelle la rentrée ou la sortie de la tige est libérée lorsque la languette est pressée et une position de blocage des mouvements de la tige par rapport au corps lorsque la languette est relâchée.More particularly, the jack 50 is interposed between the central yoke 40-2 of the control bar 38 and the yoke 14C integral with the front of the fixed seat frame 14. The body 52 of the jack 50 is connected via an axis of rotation 54 extending along the Y axis to the yoke 14C. The rod 56 of the jack 50 is, in turn, connected to the central yoke 46-2 and comprises a tongue, not shown, which presses on the rod of the jack 56 provided with a control to allow a positioning control of the rod cylinder relative to the body. Thus one obtains a position in which the retraction or the exit of the rod is released when the tongue is pressed and a position of blocking movements of the rod relative to the body when the tongue is released.

Ce mécanisme de contrôle de position de tige de vérin n'est pas décrit plus en détail car ce mécanisme est connu dans le domaine des vérins amortisseurs.This cylinder rod position control mechanism is not described in more detail because this mechanism is known in the field of damping cylinders.

La figure 5 décrit un synoptique à travers les figures 5A, 5C et 5E, les figures 5B, 5D et 5F décrivant le même synoptique mais avec une variation de l'inclinaison du siège.The figure 5 describes a synoptic through the FIGS. 5A, 5C and 5E , the Figures 5B, 5D and 5F describing the same synoptic but with a variation of the inclination of the seat.

Les figures 5A et 5B représentent le dossier 12 dans une même position du dossier, sensiblement verticale.The Figures 5A and 5B represent the folder 12 in the same position of the folder, substantially vertical.

Entre les deux positions, seule l'inclinaison de l'assise est modifiée, donc indépendamment de l'inclinaison du dossier. En effet, sur la figure 5A la barre 24 est placée dans l'encoche située à l'avant de la crémaillère 22 et la structure d'assise réglable 16 se trouve en position proche de l'horizontale.Between the two positions, only the inclination of the seat is changed, so regardless of the inclination of the backrest. Indeed, on the Figure 5A the bar 24 is placed in the notch located at the front of the rack 22 and the adjustable seat structure 16 is in a position close to the horizontal.

Sur la figure 5B, pour une même position du dossier, la barre 24 est placée dans l'encoche la plus à l'arrière de la crémaillère 22 et la structure d'assise réglable 16 est davantage inclinée vers l'arrière. Le cadre a pivoté par ses pattes de pivotement 16-1 et 16-2 par au bâti d'assise 14, autour des axes 18 portés par les pattes de liaison.On the Figure 5B , for the same position of the backrest, the bar 24 is placed in the notch at the rear of the rack 22 and the adjustable seat structure 16 is further inclined rearwardly. The frame has pivoted by its pivoting lugs 16-1 and 16-2 by the seat frame 14, about the axes 18 carried by the connecting lugs.

Le réglage est très simple, manuel et ultra rapide, sans aucun instrument nécessaire.The setting is very simple, manual and ultra fast, without any instrument needed.

Sur la figure 5C, le dossier 12 est incliné vers l'arrière. A cet effet, l'utilisateur a manoeuvré la poignée 44. Ce mouvement a libéré les mouvements de la tige 56 du vérin 50 par rapport au corps 52 dudit vérin 50. La liberté de manoeuvre est acquise tant que l'utilisateur maintient la poignée 44 inclinée.On the Figure 5C the backrest 12 is tilted backwards. For this purpose, the user has maneuvered the handle 44. This movement has released the movements of the rod 56 of the cylinder 50 relative to the body 52 of the cylinder 50. The freedom of maneuver is acquired as long as the user holds the handle 44 inclined.

Les incidences de cette libération sont nombreuses :

  • Le dossier 12 peut pivoter en inclinaison vers l'arrière lorsque l'utilisateur exerce un effort vers l'arrière sur ledit dossier,
  • Le mouvement vers l'arrière d'inclinaison du dossier 12 fait pivoter les pattes de liaison 36-1 et 36-2 dont il est solidaire par l'élément rigide 34 autour des axes 33 par rapport au bâti d'assise.
  • Les pattes de liaison 36-1 et 36-2 pivotent et donc les axes 18 qu'elles portent se trouvent déplacés vers le bas ce qui provoque une inclinaison de la structure d'assise, proportionnellement à l'inclinaison du dossier 12, indépendamment du réglage lié à la crémaillère.
The consequences of this release are numerous:
  • The backrest 12 can pivot backwardly when the user exerts a backwards force on said backrest,
  • The rearward tilting movement of the backrest 12 rotates the connecting lugs 36-1 and 36-2 which it is secured by the rigid element 34 about the axes 33 relative to the seat frame.
  • The connecting lugs 36-1 and 36-2 pivot and thus the axes 18 that they carry are moved downwards which causes an inclination of the seat structure, proportionally to the inclination of the backrest 12, independently of the adjustment linked to the rack.

On note que le vérin assure un amortissement des mouvements et un blocage en position dès que les poignées 44 sont relâchées.Note that the cylinder ensures damping movements and a locking position as soon as the handles 44 are released.

L'inclinaison du dossier nécessite un effort de la part de l'utilisateur pour aller à l'encontre des moyens de rappel élastiques R qui ont tendance à ramener le dossier vers l'avant, en inclinaison minimale. Ces moyens de rappel élastique R ont pour vocation de ramener le dossier en position sensiblement verticale, le vérin 50 assurant alors un amortissement du retour dudit dossier 12 mais cet amortissement reste limité. Ceci évite que l'utilisateur dont le dos serait éloigné du dossier incliné, reçoive un choc de la part du dossier rappelé de façon rapide par les moyens élastiques de rappel, lors de la manoeuvre de la poignée 44.The inclination of the backrest requires an effort on the part of the user to go against the elastic return means R which tend to bring the backrest forward, at minimum inclination. These elastic return means R are intended to bring the backrest in a substantially vertical position, the cylinder 50 thus ensuring a damping of the return of said file 12 but this depreciation is limited. This prevents the user whose back is away from the inclined backrest, receives a shock from the backrest quickly recalled by the elastic return means, during the operation of the handle 44.

Afin de régler la puissance des moyens de rappel élastique, il est possible de modifier le nombre des ressorts lorsque ce sont des ressorts qui sont utilisés ou la puissance des ressorts eux-mêmes.In order to adjust the power of the elastic return means, it is possible to change the number of springs when they are springs that are used or the power of the springs themselves.

Enfin, pour un même agencement, la présente invention a prévu un réglage par une butée mobile 58, en l'occurrence une vis 62 munie d'une tête 60 de manoeuvre en rotation. Cette butée mobile 58 est montée traversante sur un montant latéral du bâti d'assise 14.Finally, for the same arrangement, the present invention has provided an adjustment by a movable stop 58, in this case a screw 62 provided with a head 60 for rotating operation. This movable stop 58 is mounted through a lateral upright of the seat frame 14.

La partie intérieure de la vis est ajustée pour venir prendre appui sensiblement au droit du sommet S de l'élément longitudinal 26-1. Ainsi lorsque l'utilisateur ou un opérateur visse à l'aide de la tête 60, la vis 62 fait de plus en plus saillie à l'intérieur du bâti d'assise 14 et déplace angulairement le sommet S par rapport à l'axe vertical 28-1. De fait l'élément longitudinal 26-1 pivote et entraîne en pivotement l'autre élément longitudinal 26-2.The inner portion of the screw is adjusted to bear substantially on the right of the top S of the longitudinal member 26-1. Thus, when the user or an operator screws with the aid of the head 60, the screw 62 projects more and more inside the seat frame 14 and angularly moves the vertex S with respect to the vertical axis. 28-1. In fact, the longitudinal element 26-1 pivots and rotates the other longitudinal element 26-2.

Les deux éléments longitudinaux font un angle de moins en moins important. Les moyens élastiques de rappel R, en l'occurrence les ressorts, sont de plus en plus tendus. Le dossier est donc de plus en plus en plus difficile à manoeuvrer en inclinaison sur l'arrière.The two longitudinal elements make an angle less and less important. The elastic return means R , in this case the springs, are more and more tight. The record is therefore increasingly difficult to maneuver tilt on the back.

Un utilisateur dynamique et/ou de forte corpulence aura tendance à visser la tête 60 pour avoir un dossier ferme à manoeuvrer tandis qu'une personne fluette et/ou âgée aura tendance à dévisser ladite tête pour limiter la puissance de rappel élastique.A dynamic user and / or strong body will tend to screw the head 60 to have a firm back to maneuver while a thin and / or elderly person will tend to unscrew the head to limit the elastic return power.

Sur la figure 5D, le positionnement du dossier est identique mais on constate que la structure d'assise, qui était déjà inclinée initialement par l'ensemble barre/crémaillère, se trouve à inclinaison prononcée du fait de la manoeuvre du dossier 12 qui induit une inclinaison supplémentaire de ladite assise, cette fois proportionnelle à l'inclinaison du dossier 12.On the figure 5D , the positioning of the backrest is identical but it is found that the seat structure, which was already inclined initially by the bar / rack assembly, is pronounced inclination due to the operation of the backrest 12 which induces an additional inclination of said sitting, this time proportional to the inclination of the backrest 12.

Les figures 5E et 5F montrent une inclinaison maximale du dossier avec en 5F l'inclinaison propre maximale de la structure d'assise réglable 16 et maximale proportionnellement à l'inclinaison du dossier.The Figures 5E and 5F show a maximum inclination of the backrest with 5F the maximum proper inclination of the adjustable seat structure 16 and maximum proportionally to the inclination of the backrest.

La présente invention permet de régler aisément la puissance de rappel élastique du dossier en fonction des besoins de l'utilisateur.The present invention makes it possible to easily adjust the elastic return power of the backrest according to the needs of the user.

L'assise est inclinable proportionnellement à l'inclinaison du dossier et comprend son propre réglage d'inclinaison de façon à pouvoir, pour une même inclinaison du dossier, disposer d'un réglage de l'assise plus prononcé.The seat is tilted proportionally to the inclination of the backrest and includes its own tilt adjustment so that, for the same inclination of the backrest, have a more pronounced seat adjustment.
