Abstract

The subject of the invention is a dynamic seat. The means making it possible to cause the inclination of the backrest 2 and of the headrest 8 to vary are, at least, a vertical upright 3 on which the said backrest 2 is mounted and the lower end 4 of which is articulated to the end 5 of a means acting as a return spring 6 with dual action and the upper end of which is securely fastened to the said headrest 8, the said upright is mounted securely on a horizontal spindle 9 about which it can pivot in a vertical plane. Seat especially for motor vehicles.

Description

L'invention a pour objet un fauteuil dynamique dont l'inclinaison du dossier et de l'appui-tête varie en fonction des accélérations et décélérations du véhicule. The subject of the invention is a dynamic chair whose inclination of the backrest and the headrest varies according to the accelerations and decelerations of the vehicle.

Actuellement, il existe de nombreux sièges dont le dossier ou fauteuil est réglable angulairement par rapport à la base ou au coussin du siège. Ces réglages peuvent se faire manuellement ou à l'aide d'un moteur électrique. Dans tous les cas, une fois que le réglage du siège est choisi il ne peut être modifié que par la volonté de l'utilisateur. Or, bien souvent l'utilisateur choisit un réglage de son siège pour une position donnée, mais, la fatigue se faisant sentir, l'utilisateur change de position sans changer la position angulaire de son siège. De même, la position de l'utilisateur, la place de sa colonne vertébrale contre le dossier, varient en fonction des différentes accélérations et décélérations du véhicule, or, le siège ne change pas et ne réagit pas à tous ces paramètres.L'utilisateur a mal au dos et se fatigue, il n'y a pas un massage dynamique de la colonne vertébrale. Currently, there are many seats whose backrest or chair is angularly adjustable relative to the base or the seat cushion. These adjustments can be made manually or using an electric motor. In any case, once the seat setting is chosen it can only be changed by the will of the user. However, very often the user chooses an adjustment of his seat for a given position, but, fatigue being felt, the user changes position without changing the angular position of his seat. Likewise, the position of the user, the place of his spine against the backrest, vary according to the different accelerations and decelerations of the vehicle, but the seat does not change and does not react to all these parameters. has back pain and gets tired, there is no dynamic massage of the spine.

L'invention tend à éviter tous ces inconvénients. The invention tends to avoid all of these drawbacks.

Le fauteuil selon l'invention est un fauteuil dynamique. Le fauteuil réagit au changement de position de l'utilisateur et aux différentes accélérations et décélérations du véhicule. Cette invention ne change en rien le mécanisme existant sur les fauteuls de conception traditionnelle. The chair according to the invention is a dynamic chair. The wheelchair reacts to the change of position of the user and to the various accelerations and decelerations of the vehicle. This invention does not change the mechanism existing on traditional design chairs.

A cet effet, le fauteuil selon l'invention est composé d'un siège et d'un dossier réglables angulairement par rapport à la base ou au coussin du siège, le dossier est monté sur, au moins, un montant vertical dont l'extrémité inférieure est articulée à l'extrémité d'un vérin à haute pression ou ressort à gaz tel qu'un vérin à azote et dont l'extrémité supérieure est solidaire de l'appui-tête, ledit montant est monté dans le premier tiers de sa partie supérieure, solidaire d'un axe horizontal, autour duquel il pivote dans un plan vertical. For this purpose, the armchair according to the invention is composed of a seat and a backrest angularly adjustable relative to the base or of the seat cushion, the backrest is mounted on, at least, a vertical upright, the end of which lower is articulated at the end of a high pressure cylinder or gas spring such as a nitrogen cylinder and whose upper end is secured to the headrest, said upright is mounted in the first third of its upper part, integral with a horizontal axis, around which it pivots in a vertical plane.

Les dessins ci-joints donnés à titre d'exemple indicatifs et non limitatifs permettront de comprendre aisément l'invention. Ils représentent un mode de réalisation préféré selon l'invention. The attached drawings given by way of non-limiting example will allow the invention to be easily understood. They represent a preferred embodiment according to the invention.

La figure 1 est une vue en perspective du siège selon l'invention. Figure 1 is a perspective view of the seat according to the invention.

La figure 2 est une vue schématique, vue de côté du fauteuil mettant en évidence les mouvements du ou des montants verticaux. Figure 2 is a schematic view, side view of the chair showing the movements of the vertical upright (s).

La figure 3 est une vue schématique représentant des mouvements simultanés de la colonne vertébrale et du montant vertical dudit fauteuil. Figure 3 is a schematic view showing simultaneous movements of the spine and the vertical amount of said chair.

Le fauteuil selon l'invention est composé d'un siège 1 et d'un
dossier 2 réglables angulairement par rapport à la base ou au coussin du siège 1. The armchair according to the invention is composed of a seat 1 and a
backrest 2 adjustable angularly with respect to the base or the seat cushion 1.

Le dossier 2 est monté sur, au moins, un montant vertical 3 dont l'extrémité inférieure 4 est articulée à l'extrémité 5 d'un moyen faisant office de ressort de rappel d'un vérin 6 à haute pression ou un ressort à gaz tel qu'un vérin à azote. Ledit vérin agit en poussant pendant les trois quarts de la sortie de sa tige et en freinant progressivement la sortie de sa tige pendant le dernier quart. The backrest 2 is mounted on, at least, a vertical upright 3, the lower end 4 of which is articulated at the end 5 of a means acting as a return spring for a high-pressure cylinder 6 or a gas spring such as a nitrogen cylinder. Said cylinder acts by pushing during three quarters of the exit of its rod and by progressively braking the exit of its rod during the last quarter.

L'extrémité supérieure 7 est solidaire de l'appui-tête 8. The upper end 7 is integral with the headrest 8.

Ledit montant vertical 3 est monté dans le premier tiers de sa partie supérieure, solidaire d'un axe horizontal 9, autour duquel il peut pivoter dans un plan vertical tandis que son extrémité inférieure 4 est reliée à l'extrémité 5 du vérin 6. Said vertical upright 3 is mounted in the first third of its upper part, secured to a horizontal axis 9, around which it can pivot in a vertical plane while its lower end 4 is connected to the end 5 of the jack 6.

C'est donc le mouvement du dossier 2 sur son ou ses axes ou montants 3 qui empêchent l'engourdissement et le tassement de la colonne vertébrale 10 et permet ainsi un échange permanent entre la tête, le tronc et les jambes évitant la fatigue, les douleurs, le sommeil. It is therefore the movement of the backrest 2 on its axis or axes or uprights 3 which prevent numbness and compaction of the spinal column 10 and thus allows a permanent exchange between the head, the trunk and the legs avoiding fatigue, pain, sleep.

La tête se trouve en contact permanent avec 1 'appui-tête 8 pendant les décélérations (voir la flèche 11) et les accélérations (voir la flèche 12) ceci permet d'éviter le coup dit "coup du lapin". The head is in permanent contact with the headrest 8 during decelerations (see arrow 11) and accelerations (see arrow 12) this makes it possible to avoid the blow known as "whiplash".

Le siège 1 et les joues latérales 13 et 14 du fauteuil sont fixes. Le dossier 2 comporte donc une partie souple 15 entre les parties mobiles 2 et les parties fixes 1, 13, 14. Cette partie souple 15 peut consister en deux bandes latérales, en caoutchouc ou en latex, disposées entre le dossier 2 et les joues latérales 13 et 14. De même, la base du dossier 2 peut comporter une partie ajourée 16 très aérée pour éviter l'échauffement du bas du dos.  The seat 1 and the side cheeks 13 and 14 of the chair are fixed. The backrest 2 therefore comprises a flexible part 15 between the movable parts 2 and the fixed parts 1, 13, 14. This flexible part 15 may consist of two lateral bands, of rubber or latex, disposed between the backrest 2 and the lateral cheeks 13 and 14. Likewise, the base of the backrest 2 may include a perforated part 16 which is very ventilated to prevent the lower back from heating up.
