Ledit siègeThe present application relates to a seat capable of being mass-produced and which, for most of the conformations of the seated position, has correct adaptation conditions from the orthopedic point of view. Said seat

prévient également les escarres.also prevents bedsores.

On a déjà essayé de conformer les sièges à la constitution anatomique de l'utilisateur, la forme du siège obtenu ne peut pas s'adapter simplement aux exigences de confort recherchées au cours de la position assise de l'utilisateur.Attempts have already been made to conform the seats to the anatomical constitution of the user, the shape of the seat obtained cannot simply adapt to the comfort requirements sought during the seated position of the user.

On connaît déjà des procédés de fabrication de siège par moulage. Le brevet FR 2 737 433 propose un procédé de fabrication par moulage d'un siège, notamment d'un siège orthopédique pour handicapés. Ce procédé permet d'épouser la morphologie de l'utilisateur.Seat manufacturing processes by molding are already known. The patent FR 2 737 433 proposes a process for the manufacture by molding of a seat, in particular of an orthopedic seat for the handicapped. This process makes it possible to match the morphology of the user.

Le brevet EP 2053943 (et son équivalent US 2008/0185899 A1 ) décrit également un siège fabriqué par moulage qui épouse l'anatomie du séant de l'utilisateur.The patent EP 2053943 (and its equivalent US 2008/0185899 A1 ) also describes a seat made by molding which matches the anatomy of the user's bottom.

On connaît des procédés de fabrication en ajoutant des inserts. Le brevet EP 1131030 propose un procédé de fabrication en ajoutant plusieurs inserts les uns sur les autres, de telle sorte que cela corresponde à la morphologie de l'utilisateur.Manufacturing methods by adding inserts are known. The patent EP 1131030 proposes a manufacturing process by adding several inserts on top of each other, so that it corresponds to the morphology of the user.

On connaît des procédés de fabrication comportant des zones d'appuis recouvertes de rembourrage et d'un système de réglage de pression. Le brevet FR 2 536 975 décrit des sièges notamment pour véhicules automobiles avec des systèmes de réglage de pression sur les appuis latéraux et dorsaux du tronc humain.Manufacturing methods are known comprising support zones covered with padding and with a pressure adjustment system. The patent FR 2 536 975 describes seats in particular for motor vehicles with pressure adjustment systems on the lateral and dorsal supports of the human trunk.

On connaît des procédés de fabrication en ajoutant des cales de telle sorte que celle-ci épousent la morphologie du séant de l'utilisateur. Le kit Handipose de la société Carpenter propose différentes cales pour positionner l'utilisateur.There are known manufacturing processes by adding wedges so that they conform to the morphology of the user's buttocks. The Carpenter Handipose kit offers different wedges to position the user.

L'ensemble de ces procédés permet de fabriquer des sièges adaptés, soit en prenant des mesures directement sur l'utilisateur par le professionnel de santé qui transmettra ces informations au fabricant qui fabriquera le siège, avec l'inconvénient de mesures imparfaitement adaptées à chaque utilisateur, soit en utilisant un système de cales accrochés par des velcros, recouvertes d'une housse, avec le risque de décrocher ces cales lors par exemple d'un lavage et d'utiliser de nouvelles cales pour chaque utilisateur.All of these processes make it possible to manufacture suitable seats, either by taking measurements directly on the user by the healthcare professional who will transmit this information to the manufacturer who will manufacture the seat, with the inconvenience of measurements imperfectly adapted to each user. , or by using a system of wedges attached by Velcro, covered with a cover, with the risk of unhooking these wedges during washing, for example, and using new wedges for each user.

La présente invention, telle que définie dans la revendication 1, a donc pour objet un procédé de réalisation d'une assise sur mesure grâce à un dispositif de positionnement orthopédique qui puisse être positionné facilement et qui propose un siège unique pour chaque utilisateur.The present invention, as defined in claim 1, therefore relates to a method for producing a made-to-measure seat using an orthopedic positioning device which can be positioned easily and which offers a single seat for each user.

A cet effet, l'invention prévoit différentes cales, notamment cales pelviennes, cales d'abduction et cales d'adduction, empilables, positionnées sur des emplacements prédéfinis sur une assise ou embase, l'ensemble étant positionné sur un plateau de fixation réglable d'avant en arrière, caractérisé par le fait que ces éléments empilables favorisent une bonne stabilité et permettent une meilleure distribution des pressions à l'interface séant-siège. Ces éléments sont utilisés par le professionnel de la santé, notamment un ergothérapeute et un kinésithérapeute, pour prendre des mesures qui sont transmises au fabricant qui fraisera l'assise finale dans un bloc de mousse réticulée à cellules fermées faite de polyéthylène ou toutes autres sortes de mousses. Ce bloc sera ensuite recouvert d'une housse favorisant une meilleure hygiène à l'utilisateur. L'utilisateur obtiendra donc son assise unique. Les cales pourront être utilisées pour d'autres utilisateurs par le professionnel de santé.To this end, the invention provides various wedges, in particular pelvic wedges, abduction wedges and adduction wedges, stackable, positioned on predefined locations on a seat or base, the assembly being positioned on an adjustable fixing plate of front to back, characterized by the fact that these stackable elements promote good stability and allow better distribution of pressures at the seat-back interface. These elements are used by the health professional, in particular an occupational therapist and a physiotherapist, to take measurements which are transmitted to the manufacturer who will mill the final seat in a block of reticulated foam with closed cells made of polyethylene or any other kind of foams. This block will then be covered with a cover promoting better hygiene for the user. The user will therefore obtain his unique seat. The wedges may be used for other users by the healthcare professional.

Dans ce qui suit, l'invention est expliquée plus en détail à l'aide d'un exemple d'exécution du siège illustré par le dessin dans lequel :

  • La figure 1 est une vue en perspective du siège avec l'ensemble des cales à positionner sur l'assise.
  • La figure 2 est une vue en perspective de l'assise fraisée.
In the following, the invention is explained in more detail with the aid of an example of execution of the seat illustrated by the drawing in which:
  • The figure 1 is a perspective view of the seat with all the wedges to be positioned on the seat.
  • The figure 2 is a perspective view of the milled seat.

La figure 1 représente un siège composé d'une mousse réticulée à cellules fermées faite de polyéthylène carrée de dimension 400 mm de long par 400 mm de large et 50 mm d'épaisseur, avec emplacement prévu pour des inserts au niveau des ischions (6 sur la figure 1).The figure 1 represents a seat made of reticulated closed-cell foam made of square polyethylene measuring 400 mm long by 400 mm wide and 50 mm thick, with space provided for inserts at seat bone level (6 on the figure 1 ).

Différents rajouts en forme de rectangle sont ajoutés à la mousse réticulée, permettant d'obtenir une dimension de 500 mm de long par 500 mm de large et 50 mm d'épaisseur.Various additions in the shape of a rectangle are added to the reticulated foam, making it possible to obtain a dimension of 500 mm long by 500 mm wide and 50 mm thick.

Trois cales d'adduction ergonomiques de 2 cm de hauteur chacune, empilables, solidarisées par velcro, venant caler au niveau des cuisses (3,4 sur la figure 1) sont placées sur la mousse carrée. Les dimensions de ces cales ergonomiques seront, par exemple, de longueur 160 mm pour chacune, évasées d'environ 30° du côté cuisses, de largeur variant linéairement de 50 mm à la base de la cale la plus basse à 15 mm au sommet de la cale la plus haute, et un retour arrière rayonné pour épouser la forme des fesses, pour avoir une largeur maximale de 80 mm à la base de la cale la plus basse, 45 mm au sommet de la cale la plus haute.Three ergonomic adduction wedges, 2 cm high each, stackable, secured by velcro, wedged at thigh level (3.4 on the figure 1 ) are placed on the square foam. The dimensions of these ergonomic wedges will, for example, be 160 mm long each, flared by approximately 30° on the thigh side, with a width varying linearly from 50 mm at the base of the lowest wedge to 15 mm at the top of the highest wedge, and a radiated rear return to match the shape of the buttocks, to have a maximum width of 80 mm at the base of the lowest wedge, 45 mm at the top of the highest wedge.

Trois cales ergonomiques de 2 cm de hauteur chacune à gauche, trois cales ergonomiques de 2 cm de hauteur chacune à droite, empilables, solidarisées par velcro, venant caler au niveau pelvien, empêchant le glissement latéral ainsi que la rotation du bassin (1,2 sur la figure 1) sont ensuite placées sur la mousse carrée.Three ergonomic wedges each 2 cm high on the left, three ergonomic wedges each 2 cm high on the right, stackable, secured by Velcro, wedged at pelvic level, preventing lateral slippage and rotation of the pelvis (1,2 on the figure 1 ) are then placed on the square foam.

Trois cales d'abduction ergonomique de 2 cm de hauteur venant se placer entre les cuisses, permettant d'épouser les formes inférieures et intérieures de la cuisse (5 sur la figure 1) sont enfin placées sur la mousse carrée.Three ergonomic abduction wedges, 2 cm high, placed between the thighs, allowing the lower and inner forms of the thigh to be matched (5 on the figure 1 ) are finally placed on the square foam.

A cela se rajoutent des cales d'inclinaison, venant se mettre sous l'assise, sous un des quatre côtés du carré. Ces cales ont différentes épaisseurs. Elles permettent l'inclinaison, soit vers la gauche, vers la droite, en avant ou en arrière de l'ensemble de l'assise. Ces cales sont positionnés de telle sorte qu'elles occupent la moitié du carré de base 400 mm par 400 mm ou 500 mm par 500 mm, soit 200 mm ou 250 mm.To this are added tilt wedges, which are placed under the seat, under one of the four sides of the saloon. These wedges have different thicknesses. They allow tilting, either to the left, to the right, forwards or backwards of the entire seat. These wedges are positioned so that they occupy half of the base square 400 mm by 400 mm or 500 mm by 500 mm, i.e. 200 mm or 250 mm.

A cela se rajoutent des cales d'obliquité, venant se mettre sous l'assise, sous un angle du carré. Ces cales ont différentes épaisseurs, par exemple 20 mm, 40 mm ou 60 mm. Elles permettent l'inclinaison oblique de l'ensemble de l'assise.To this are added wedges of obliqueness, coming to be put under the seat, under an angle of the square. These wedges have different thicknesses, for example 20 mm, 40 mm or 60 mm. They allow the oblique inclination of the entire seat.

A cela se rajoutent différents inserts pour ischions positionnés entre les cales pelviennes, d'adduction et d'abduction. Ces inserts pourront être en mousse, en gel viscoélastique de polyuréthane, à cellules pneumatiques avec au moins une zone de gonflage, ou plusieurs zones de gonflage ou avec tous types de matières ou avec tous types d'inserts permettant de soutenir les ischions.Added to this are various seat bone inserts positioned between the pelvic, adduction and abduction wedges. These inserts may be made of foam, of viscoelastic polyurethane gel, of pneumatic cells with at least one inflation zone, or several inflation zones or with all types of materials or with all types of inserts making it possible to support the seat bones.

Ces inserts couvrent la surface du séant, et reviennent légèrement sous les cuisses de 33 % de la distance restante entre les ischions et le bord du coussin.These inserts cover the surface of the buttocks, and return slightly under the thighs by 33% of the remaining distance between the seat bones and the edge of the cushion.

Tous les éléments décrits s'imbriquent et sont recouverts d'un tissu agrippant, permettant la solidarisation par velcro. Des repères sont visibles sur l'assise carrée, et seront reportés dans la fiche de mesure ainsi que les cales choisies, pour connaître l'emplacement souhaité.All the elements described fit together and are covered with a gripping fabric, allowing velcro fastening. Marks are visible on the square seat, and will be reported in the measurement sheet as well as the chosen wedges, to know the desired location.

Une fois les éléments imbriqués en fonction de la morphologie de l'utilisateur avec le concours de l'ergothérapeute et du kinésithérapeute, les mesures correspondant à l'emplacement de chacun des éléments seront envoyées au fabricant pour fraiser un bloc de mousse réticulée à cellules fermées faite de polyéthylène correspondant à l'utilisateur. Ce bloc de mousse sera ensuite recouvert par une housse dont la partie en contact avec l'utilisateur sera en fibre d'élasthanne imperméabilisée extensible en longueur et en largeur pour assurer une meilleure hygiène et la partie en contact avec le dispositif sera en mousse souple type polyether, mousse polyuréthanne haute résilience ou mousse viscoélastique de 5 mm d'épaisseur.Once the elements are nested according to the morphology of the user with the assistance of the occupational therapist and the physiotherapist, the measurements corresponding to the location of each of the elements will be sent to the manufacturer to mill a block of reticulated foam with closed cells made of polyethylene corresponding to the user. This block of foam will then be covered by a cover whose part in contact with the user will be made of waterproof elastane fiber stretchable in length and width to ensure better hygiene and the part in contact with the device will be made of soft foam type polyether, high resilience polyurethane foam or 5 mm thick viscoelastic foam.

L'invention sera ensuite avantageusement complétée par un dossier galbant, creusé au niveau de la colonne vertébrale pour éviter les points d'appuis et équipé de cales tronc réglables en largeur.The invention will then be advantageously supplemented by a contouring backrest, hollowed out at the level of the spine to avoid the points of support and equipped with width-adjustable trunk wedges.

On pourra également installer des capteurs de pression sur l'assise, ou sur chacune des cales de l'assise, ou sur le dossier lors de la prise de mesures afin d'affiner le réglage des éléments.It is also possible to install pressure sensors on the seat, or on each of the wedges of the seat, or on the backrest when taking measurements in order to refine the adjustment of the elements.

L'invention sera installée sur un plateau de fixation qui est réglable d'avant en arrière (7 sur la figure 1).The invention will be installed on a fixing plate which is adjustable from front to back (7 on the figure 1 ).
