Abstract

Device for an ergonomical postural balancing and dynamic supporting of elements or segments of the human body with mechanically synchronized movable supports, particularly a variable ischio-lumbar adjustment seat. The weight of a corporal element or segment controls the displacement of the support (1) (seating) pivoting about a fixed axis (2) or sliding on rails which drives mechanically, through a flexible transmission (5) sliding on a roller (6), the rocking of the lever support (3) (backrest) about the fixed axis (4), sustaining in a corrected posture the corporal segment bearing against the latter support. It performs a balanced and harmonious supporting of one or a plurality of corporal segments independently of the position which may be modified as desired and at any time.

Description

DISPOSITIF D'EQUILIBRAGE POSTURAL ERGONOMIQUE ET DE SOUTIEN POUR LE CORPS HUMAIN, NOTAMMENT UN SIEGE A CALAGE VARIABLE ISCHIO-LOMBAIRE ERGONOMIC POSTURAL BALANCING AND SUPPORT DEVICE FOR THE HUMAN BODY, IN PARTICULAR AN ISCHIO-LUMBAR VARIABLE SETTING SEAT

Dispositif d'équilibrage postural utilisant des supports dynamiques du corps humain récupérant le poids d'éléments ou de segments corporels pour en soutenir d'autres par l'intermédiaire de surfaces mobiles synchronisés mécaniquement ou par tout autre système approprié, et agissant par effet de levier, notamment un siège basé sur ce principe.Postural balancing device using dynamic supports of the human body recovering the weight of elements or body segments to support others by means of mobile surfaces synchronized mechanically or by any other suitable system, and acting by leverage , in particular a seat based on this principle.

La présente invention concernant un dispositif de soutien actif du corps humain a pour principe la mobilisation d'un premier support, actionné par le poids d'un segment corporel entraînant dans son mouvement, par une liaison notamment mécanique, un second support, soutenant, par effet de levier, un autre segment corporel. Le présent dispositif voit sa réalisation principale dans un siège à géométrie variable et tous types de sièges (sièges d ' ameublement courant , sièges pliants , sièges de camping ou de plage, sièges automobiles, sièges de transports en commun et de tous autres véhicules, sièges de coiffeur, sièges de salles de spectacle, sièges à utilisation médicale, à titre d'exemples non limitatifs).The present invention relating to an active support device for the human body has as a principle the mobilization of a first support, actuated by the weight of a body segment causing in its movement, by a linkage in particular mechanical, a second support, supporting, by leverage, another body segment. The present device sees its main embodiment in a seat with variable geometry and all types of seats (standard furniture seats, folding seats, camping or beach seats, car seats, seats for public transport and all other vehicles, seats hairdresser, performance hall seats, seats for medical use, by way of non-limiting examples).

Les sièges existants présentant un système articulé, à assise et dossier solidaires ou non et à appui lombaire passif, n'offrent pas de contrepoussée correctrice active soutenant les lombes lors du "glissement" inévitable des ischions sur l'assise. Le présent dispositif remédie aux inconvénients précités en respectant les diverses modifications posturales et en maintenant dans toutes les positions une posture corrigée, par un calage dynamique harmonieux et équilibré des divers segments corporels. D'autre part, peu de sièges offrent une assise inclinable vers l'arrière comme vers l'avant, favorisant les positions de repos et de travail. II faut une charge importante (de l'ordre de 10 à 15 kg chez un adulte moyen) pour redresser, sans le moindre effort musculaire, le socle pelvien affaissé sur un siège courant. L'innovation du présent siège comporte un système de compensation récupérant le poids du tronc qui agit comme force déformante lombaire pour en faire l'agent de la correction posturale. II offre les avantages suivants :Existing seats with an articulated system, with or without integral seat and backrest and with passive lumbar support, do not offer active corrective counterpush supporting the lower back during the inevitable "sliding" of the ischia on the seat. The present device overcomes the aforementioned drawbacks by respecting the various postural modifications and by maintaining in all positions a corrected posture, by a harmonious and balanced dynamic setting of the various body segments. On the other hand, few seats offer a reclining seat backwards as well as forward, favoring the rest and working positions. It takes a significant load (of the order of 10 to 15 kg in an average adult) to straighten, without the slightest muscular effort, the pelvic pedestal collapsed on a current seat. The innovation of this seat includes a compensation system recovering the weight of the trunk which acts as a lumbar deforming force to make it the agent of postural correction. It offers the following advantages:

1) Soutien lombaire permanent (en position de repos et vigilant) par la poussée du dossier, proportionnelle au glissement des ischions sur l'assise;1) Permanent lumbar support (in the resting and vigilant position) by pushing the backrest, proportional to the sliding of the ischia on the seat;

2) Positions de repos, assis vigilant et de travail, cette dernière répondant aussi à certains types de handicaps physiques (arthrodèse du genou ou de la hanche, membre inférieur plâtré en rectitude, etc.) et favorisant progressivement la réhabilitation fonctionnelle vers un assis plus horizontalisé;2) Resting positions, vigilant sitting and working, the latter also responding to certain types of physical disabilities (knee or hip arthrodesis, lower limb plastered straight, etc.) and gradually promoting functional rehabilitation towards a more seated horizontalized;

3) La correction active de la région lombaire obtenue par ce siège présente l'énorme avantage d'améliorer la totalité de la statique rachidienne et d'éviter les aggravations des attitudes vicieuses du rachis .3) The active correction of the lumbar region obtained by this seat has the enormous advantage of improving the totality of the spinal statics and to avoid aggravation of the vicious attitudes of the spine.

Un système de blocage existant peut être adapté sur ce type de siège, soit en bloquant l'assise ou le dossier, soit en bloquant le système de transmission entre le dossier et l'assise, séparément ou conjointement. Un système de freinage (à galets, à disque, par inertie à l'aide de ressorts ou de masselottes, à titre d'exemples non limitatifs, notamment dans le cas du siège de véhicule) peut être intégré au siège.An existing blocking system can be adapted on this type of seat, either by blocking the seat or the backrest, or by blocking the transmission system between the backrest and the seat, separately or jointly. A braking system (roller, disc, inertia using springs or weights, as non-limiting examples, especially in the case of the vehicle seat) can be integrated into the seat.

Le siège à calage variable ischio-lombaire a pour principe de récupérer la force de glissement des ischions sur l'assise mobile et de la communiquer au dossier, lui-même pivotant auquel elle est solidarisée par l'intermédiaire d'une sangle passant sur un rouleau, ou par tout autre moyen de solidarisation, mécanique ou non» Le dossier agit alors comme un levier, mû indirectement par le déplacement de l'assise. Ce siège respecte ainsi les principes ergonomiques de base et réalise un rattrapage permanent du soutien lombaire, toutes les fois que le tronc repose en appui sur le dossier.The principle of the variable ischio-lumbar seat is to recover the sliding force of the ischia on the mobile seat and to communicate it to the backrest, itself pivoting to which it is secured by means of a strap passing over a roller, or by any other means of joining, mechanical or not ”The backrest then acts as a lever, moved indirectly by the movement of the seat. This seat thus respects the basic ergonomic principles and realizes a permanent take-up of the lumbar support, whenever the trunk rests on the backrest.

D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante : selon une forme de réalisation préférentielle, le système de liaison solidarisant l'assise et le dossier peut être constitué par de la sangle (de type ceinture de sécurité) ayant un coefficient de deformation et d'élasticité le plus faible possible, passant sur un rouleau ou tout autre système de transmission. Selon diverses variantes, on peut envisager l'utilisation de câble, de courroie ou de tout autre système de liaison, souple ou rigide, à titre d'exemples non limitatifs en référence aux dessins annexés. L'assise peut également coulisser sur un ou plusieurs rails fixes, courbes ou non, ou être mue par pression ou par pesée ou tout autre système.Other characteristics and advantages of the invention will emerge from the following description: according to a preferred embodiment, the connection system securing the seat and the backrest may be constituted by a strap (of the seat belt type) having a coefficient of deformation and elasticity as low as possible, passing on a roller or any other transmission system. According to various variants, it is possible to envisage the use of cable, belt or any other connecting system, flexible or rigid, by way of nonlimiting examples with reference to the appended drawings. The seat can also slide on one or more fixed rails, curved or not, or be moved by pressure or by weighing or any other system.

Les matériaux convenants sont ceux de type courant pour la fabrication de tous sièges, mais il est préférable que l'assise soit recouverte de tissu d'ameublement non glissant, assurant une bonne adhérence.Suitable materials are those of common type for the manufacture of all seats, but it is preferable that the seat is covered with non-slip upholstery fabric, ensuring good grip.

Le piètement peut être métallique, en bois, en plastique ou autre matériau, de formes diverses, à pied unique ou multiple. L'ensemble du siège peut être pliant ou non.The base can be metallic, wooden, plastic or other material, of various shapes, with single or multiple legs. The whole seat can be foldable or not.

La figure 1 représente un schéma de profil du siège à calage variable ischio-lombaire. L'assise mobile (1) pivote autour d'un axe, de préférence fixe (2), glisse sur des rails (10) (fig. 2) ou est mue sur des galets ou des roulettes (17) (fig. 3) et communique la force de glissement au dossier (3), lui-même pivotant autour d'un axe, de préférence fixe (4). Dans ce déplacement, dossier et assise mobiles sont solidarisés par l'intermédiaire d'un système de transmission souple mais non élongeable (5) passant sur un rouleau ou une poulie, de préférence fixe (6). La figure 2 représente une variante pour siège de véhicule. Dans cette variante, l'assise (1) coulisse sur un ou plusieurs rails (10). La partie supérieure du dossier (7) étant fixe, la partie mobile du dossier (3) répondant au présent dispositif présente, de part et d'autre de son axe (4) de pivotement, une partie inférieure (8) jouant le rôle de soutien lombaire dynamique et une partie supérieure (9), intérieure à l'armature du dossier (7) et ne joue qu'un rôle de bras de levier purement mécanique.Figure 1 shows a profile diagram of the seat with variable ischio-lumbar support. The mobile seat (1) pivots about an axis, preferably fixed (2), slides on rails (10) (fig. 2) or is moved on rollers or rollers (17) (fig. 3) and communicates the sliding force to the backrest (3), itself pivoting about an axis, preferably fixed (4). In this movement, the movable backrest and seat are joined together by means of a flexible but non-elongable transmission system (5) passing over a roller or a pulley, preferably fixed (6). FIG. 2 represents a variant for a vehicle seat. In this variant, the seat (1) slides on one or more rails (10). The upper part of the backrest (7) being fixed, the mobile part of the backrest (3) responding to this device has, on either side of its pivot axis (4), a lower part (8) playing the role of dynamic lumbar support and an upper part (9), internal to the frame of the backrest (7) and only acts as a purely mechanical lever arm.

La figure 3 représente, selon le même principe, un dispositif de coussins articulés à placer sur une chaise courante pour en améliorer le confort. L'assise mobile (1) mue sur des roulettes (17) communique la force de glissement au dossier (3), fixé sur une entretoise (18) pivotant autour d'un axe fixe (4). Dans ce déplacement, dossier et assise sont solidarisés par l'intermédiaire d'un système de transmission souple (5) passant sur un rouleau ou une poulie fixe (6). La figure 4 représente le dispositif général, pouvant être utilisé selon diverses dimensions comme cale-dos, appuie-tête, repose-bras (par exemple). Le support (1) actionné par un élément ou segment corporel (tels que ischions, dos, coude, par exemple) entraîne, par le mécanisme de transmission (5, 6) le support (3) qui soutient dynamiquement un autre élément ou segment corporel tels que dos, tête, avant-bras, par exemple), en pivotant sur un axe (4).Figure 3 shows, according to the same principle, a device of articulated cushions to be placed on a common chair to improve comfort. The mobile seat (1) moved on casters (17) communicates the sliding force to the backrest (3), fixed on a spacer (18) pivoting around a fixed axis (4). In this movement, the backrest and seat are joined together by means of a flexible transmission system (5) passing over a roller or a fixed pulley (6). Figure 4 shows the general device, which can be used in various dimensions as back rest, headrest, armrest (for example). The support (1) actuated by an element or body segment (such as ischia, back, elbow, for example) drives, by the transmission mechanism (5, 6) the support (3) which dynamically supports another element or body segment such as back, head, forearm, for example), by pivoting on an axis (4).

La figure 5 représente une autre variante qui utilise un socle à bascule hémicylindrique (11) à l'une des extrémités duquel est fixé le support (dossier) (3) et à l'autre extrémité la transmission mécanique (sangle) (5) qui passe dans une ouverture (12) pratiquée dans le support (dossier) (3) et se prolonge jusqu'au support (assise) (1) auquel elle est solidarisée.FIG. 5 represents another variant which uses a semi-cylindrical rocker base (11) at one end of which the support (backrest) (3) is fixed and at the other end the mechanical transmission (strap) (5) which passes through an opening (12) made in the support (backrest) (3) and extends to the support (seat) (1) to which it is secured.

La figure 6 (variante de la figure 5) représente une gourde de camping ou une malette ou tout autre objet utilitaire (notamment de plage ou de camping), notamment en matière plastique, servant d'appuie-tête ou de cale-dos (3) (pour la plage, le camping ou tout autre usage). Elle présente une base hémicylindrique (11), une ouverture (12) qui permet le passage notamment d'une serviette de plage qui sert de support (assise ou appuie-dos) (1) et qui est bloquée par un système de fixation instantanné quel qu'il soit (13), situé à l'arrière de la gourde et passant ou non dans l'ouverture (12). La gourde présente un goulot à pas de vis (14), muni d'un bouchon (15) et éventuellement une poignée (16) .FIG. 6 (variant of FIG. 5) represents a camping flask or a briefcase or any other utility object (in particular beach or camping), in particular made of plastic, serving as a headrest or back rest (3 ) (for the beach, camping or any other use). It has a semi-cylindrical base (11), an opening (12) which allows the passage in particular of a beach towel which serves as support (seat or backrest) (1) and which is blocked by an instant fixing system which whether it is (13), located at the rear of the gourd and whether or not passing through the opening (12). The flask has a screw thread neck (14), provided with a stopper (15) and possibly a handle (16).

Ce dispositif de support corporel ainsi décrit, tel que siège à calage variable ischio-lombaire, peut être appliqué aux usages suivants, à titre d'exemples non limitatifs : siège d'ameublement courant, chaise de malade (malades souffrant d'une immobilisation en rectitude complète d'un membre infé rieur, par exemple), pouvant être aménagée en chaise percée par une modification appropriée de l'assise; adaptation à la tête articulée d'un lit (de malade, par exemple); cale-dos (permettant d'asseoir un malade au bord de son lit, par exemple); matériel de camping et de plage (cale-dos, repose-tête), basé sur le même principe ou sur la variante présentée sur la figure 5; repose-bras mobile à positions variables (permettant de faciliter le travail manuel précis de diverses professions). This body support device thus described, such as a seat with variable ischio-lumbar support, can be applied to the following uses, by way of nonlimiting examples: common furniture seat, patient's chair (patients suffering from immobilization in complete straightness of an inferior member laughing, for example), which can be converted into a chair with an appropriate modification of the seat adaptation to the articulated head of a bed (for the sick, for example); back rest (allowing a patient to sit on the edge of his bed, for example); camping and beach equipment (back rest, headrest), based on the same principle or on the variant shown in Figure 5; mobile armrest with variable positions (to facilitate precise manual work of various professions).
