Description

FAUTEUIL ESCAMOTABLE POUR UN AERONEF La présente invention se rapporte à un fauteuil escamotable pour un aéronef. Une cabine d'aéronef peut comprendre pour les membres d'équipage un ou plusieurs fauteuils d'appoint sous forme de strapontin. be manière connue, un fauteuil d'appoint comprend d'une part une partie fixe solidarisée à une paroi verticale de l'aéronef, comprenant un dossier et un appui- tête, et d'autre part, une assise rabattable susceptible d'occuper une première position déployée dans laquelle l'assise est horizontale et permet à une personne de s'assoir et une seconde position rabattue dans laquelle l'assise est verticale et plaquée contre le dossier. The present invention relates to a retractable armchair for an aircraft. An aircraft cabin may include for the crew members one or more booster seats. In known manner, an auxiliary chair comprises firstly a fixed part secured to a vertical wall of the aircraft, comprising a backrest and a headrest, and secondly, a folding seat capable of occupying a first deployed position in which the seat is horizontal and allows a person to sit and a second folded position in which the seat is vertical and pressed against the backrest.

Selon un mode de réalisation, un fauteuil d'appoint comprend une coque avec une plaque verticale et deux montants perpendiculaires à la plaque, un de chaque côté de la plaque. Le dossier est fixé sur la plaque verticale et l'appui-tête est relié à la coque par l'intermédiaire d'une glissière qui autorise un mouvement relatif vertical entre l'appui-tête et la coque. According to one embodiment, an auxiliary chair comprises a shell with a vertical plate and two uprights perpendicular to the plate, one on each side of the plate. The backrest is fixed on the vertical plate and the headrest is connected to the hull by means of a slide which allows a vertical relative movement between the headrest and the hull.

L'assise est reliée aux montants de la coque par l'intermédiaire d'une liaison autorisant un mouvement de pivotement autour d'un axe horizontal, parallèle à la plaque verticale de la coque. Bien que ce type de fauteuil permette de réduire le volume d'encombrement en position rabattue, il subsiste toujours une partie en saillie par rapport à la paroi verticale sur laquelle le fauteuil d'appoint est rapporté. Aussi, ce type de fauteuil d'appoint peut difficilement être implanté dans une soute d'un avion-cargo car il tend à gêner, voire empêcher, le chargement-déchargement des conteneurs. The seat is connected to the uprights of the hull by means of a connection allowing a pivoting movement about a horizontal axis, parallel to the vertical plate of the hull. Although this type of chair reduces the amount of space in the folded position, there always remains a projecting portion relative to the vertical wall on which the booster chair is reported. Also, this type of booster chair can hardly be implanted in a hold of a cargo plane as it tends to hinder or even prevent the loading and unloading of containers.

La présente invention vise à pallier les inconvénients de l'art antérieur en proposant un fauteuil escamotable qui n'encombre pas le volume utile en position escamotée. A cet effet, l'invention a pour objet un fauteuil escamotable pour un aéronef 5 comprenant un plancher avec une structure porteuse comportant des renforts orientées selon deux directions, ledit fauteuil comprenant un châssis et une assise pivotante par rapport au châssis, caractérisé en ce que le châssis comprend au moins un élément télescopique, avec deux parties qui peuvent coulisser l'une par rapport à l'autre entre une position étendue et une position 10 rétractée, une première partie étant pivotante par rapport au plancher de manière à loger le fauteuil dans le plancher en position escamotée entre les renforts, l'assise étant reliée à l'autre partie de manière pivotante. D'autres caractéristiques et avantages ressortiront de la description qui va suivre de l'invention, description donnée à titre d'exemple uniquement, en regard 15 des dessins annexés sur lesquels : - la figure lA est une vue en perspective d'un fauteuil selon l'invention en position rétractée, - la figure 1B est une vue en perspective du fauteuil de la figure lA en position étendue, 20 - la figure 2 est une vue en perspective d'une partie d'un plancher d'un aéronef avec une trappe en position fermée, - la figure 3 est une vue en perspective du plancher de la figure 2 avec la trappe en position ouverte dégageant un logement contenant un fauteuil selon l'invention, 25 - la figure 4 est une vue en perspective d'un fauteuil selon l'invention en position rétractée, sorti de son logement, - la figure 5 est une vue en perspective d'un fauteuil selon l'invention en position étendue, sorti de son logement, et 2 98045 7 3 - la figure 6 est une vue en perspective d'un fauteuil selon l'invention en position déployée. Sur les figures 1A, 1B, 4 à 6, on a représenté en 10 un fauteuil escamotable selon l'invention qui comprend un châssis 12 et au moins une assise 14 susceptible d'occuper une première position déployée ou elle est disposée approximativement à l'horizontale, comme illustré sur la figure 6, ou une deuxième position rabattue, comme illustré sur les figures 1A, 1B, 4 et 5. Le châssis 12 comprend deux montants 16.1 et 16.2 parallèles entre lesquels peut pivoter l'assise 14 autour d'un axe de pivotement 18 horizontal qui s'étend entre les deux montants 16.1 et 16.2. En variante, l'assise 14 peut pivoter grâce à deux axes de pivotement 18 alignés, un pour chaque montant. Selon un mode de réalisation, le châssis 12 se présente sous la forme d'une coque qui comprend une plaque centrale 20 sensiblement rectangulaire et deux montants 16.1 et 16.2, reliés perpendiculairement à la plaque centrale 20 au 15 niveau de deux bords opposés de la plaque centrale 20. La plaque centrale 20 forme le dossier du fauteuil. Avantageusement, un élément rembourré 22 peut être rapporté sur la plaque centrale 20 pour améliorer le confort. be la même manière, l'assise 14 peut être rembourrée. 20 be préférence, le fauteuil comprend un appui-tête 24. Ce dernier peut être réglable en hauteur et rembourré pour améliorer le confort. L'assise, le dossier, l'appui-tête, la liaison entre l'assise et les montants ne sont pas plus décrits car ils sont connus et peuvent être identiques à ceux de l'art antérieur. 25 be manière connue, comme illustré sur la figure 2, un aéronef comprend un plancher 26. Ce dernier comprend une structure porteuse sur laquelle sont rapportées des plaques 28. La structure porteuse comprend des traverses 30 disposées selon une première direction et des rails 32 disposés selon une seconde direction perpendiculaire à la première. Pour donner un ordre de grandeur, l'écart entre les traverses 30 est de l'ordre de 800 mm et celui entre les rails 32 est de l'ordre de 730 mm dans la zone avant du fuselage d'une première famille d'avions. Pour d'autres familles d'avions, l'écartement entre deux traverses peut être de l'ordre de 530 mm ou 650 mm. Les écartements entre les traverses et les rails sont imposés pour répondre aux contraintes mécaniques à savoir pour conférer une résistance mécanique à la structure porteuse lui permettant de supporter des conteneurs. The present invention aims to overcome the disadvantages of the prior art by providing a retractable chair that does not clutter the useful volume in the retracted position. For this purpose, the invention relates to a retractable armchair for an aircraft 5 comprising a floor with a supporting structure comprising reinforcements oriented in two directions, said chair comprising a frame and a seat pivoting relative to the frame, characterized in that the frame comprises at least one telescopic element, with two parts which are slidable relative to each other between an extended position and a retracted position, a first part being pivotable with respect to the floor so as to house the chair in the floor in the retracted position between the reinforcements, the seat being pivotally connected to the other part. Other features and advantages will become apparent from the following description of the invention, a description given by way of example only, with reference to the appended drawings, in which: FIG. 1A is a perspective view of a chair according to In the retracted position, FIG. 1B is a perspective view of the chair of FIG. 1A in extended position, FIG. 2 is a perspective view of a portion of a floor of an aircraft with a hatch in the closed position, - Figure 3 is a perspective view of the floor of Figure 2 with the hatch in the open position releasing a housing containing a chair according to the invention, - Figure 4 is a perspective view of a chair according to the invention in retracted position, taken out of its seat, - Figure 5 is a perspective view of a chair according to the invention in extended position, taken out of its seat, and 2 68045 7 3 - Figure 6 is a perspective view of an armchair invention in the deployed position. In Figures 1A, 1B, 4 to 6, there is shown in 10 a retractable chair according to the invention which comprises a frame 12 and at least one seat 14 may occupy a first deployed position or is disposed approximately at the horizontal, as shown in Figure 6, or a second folded position, as shown in Figures 1A, 1B, 4 and 5. The frame 12 comprises two uprights 16.1 and 16.2 parallel between which can rotate the seat 14 around a horizontal pivot axis 18 which extends between the two uprights 16.1 and 16.2. Alternatively, the seat 14 can rotate through two aligned pivot axes 18, one for each amount. According to one embodiment, the frame 12 is in the form of a shell which comprises a substantially rectangular central plate 20 and two uprights 16.1 and 16.2 connected perpendicularly to the central plate 20 at two opposite edges of the plate Central 20. The central plate 20 forms the back of the chair. Advantageously, a padded element 22 can be attached to the central plate 20 to improve comfort. be the same way, the seat 14 can be padded. Preferably, the chair includes a headrest 24. The chair can be height-adjustable and padded to improve comfort. The seat, the backrest, the headrest, the connection between the seat and the uprights are no longer described because they are known and may be identical to those of the prior art. In known manner, as illustrated in FIG. 2, an aircraft comprises a floor 26. The latter comprises a bearing structure to which plates 28 are attached. The carrying structure comprises sleepers 30 arranged in a first direction and rails 32 arranged in a second direction perpendicular to the first. To give an order of magnitude, the distance between the crosspieces 30 is of the order of 800 mm and that between the rails 32 is of the order of 730 mm in the forward zone of the fuselage of a first family of aircraft . For other families of aircraft, the distance between two sleepers may be of the order of 530 mm or 650 mm. The spacings between the sleepers and the rails are imposed to meet the mechanical constraints, namely to give mechanical strength to the support structure enabling it to support containers.

Selon l'invention, les montants 16.1 et 16.2 peuvent pivoter par rapport à la structure porteuse entre une première position dite escamotée dans laquelle le fauteuil est dissimulé dans la structure porteuse du plancher et une autre position déployée dans laquelle le dossier du fauteuil 10 est sensiblement vertical après pivotement des montants 16.1 et 16.2. According to the invention, the uprights 16.1 and 16.2 can pivot relative to the support structure between a first so-called retracted position in which the chair is concealed in the supporting structure of the floor and another deployed position in which the back of the chair 10 is substantially vertical after pivoting the uprights 16.1 and 16.2.

En position escamotée, le fauteuil 10 est disposé dans l'espace prévu entre deux traverses 30 consécutives et deux rails 32 consécutifs. Ainsi, dans cette position, aucune partie du fauteuil ne vient en saillie dans le volume utile situé au-dessus du plancher. Selon un mode de réalisation, le plancher 26 comprend un caisson 34, solidarisé à la structure porteuse sous les plaques 28, qui assure la fonction de logement pour le fauteuil. Ce caisson 34 a une forme parallélépipédique et comprend un fond et quatre parois latérales, la face supérieure étant dégagée. Ce caisson 34 permet de protéger le fauteuil lorsqu'il est en position escamotée. In the retracted position, the chair 10 is disposed in the space provided between two consecutive crosspieces 30 and two consecutive rails 32. Thus, in this position, no part of the chair comes protruding into the useful volume above the floor. According to one embodiment, the floor 26 comprises a box 34, secured to the supporting structure under the plates 28, which provides the housing function for the chair. This box 34 has a parallelepipedal shape and comprises a bottom and four side walls, the upper face being disengaged. This box 34 protects the chair when in the retracted position.

Les dimensions du caisson 34 sont adaptées pour qu'il puisse se loger entre deux traverses 30 consécutives et deux rails 32 consécutifs tout en offrant un volume maximal. The dimensions of the box 34 are adapted so that it can be housed between two consecutive crosspieces 30 and two rails 32 consecutive while providing maximum volume.

Les montants 16.1 et 16.2 peuvent pivoter autour d'un axe de pivotement 36 qui s'étend entre deux parois latérales du caisson 34 parallèles aux rails 32. En variante, le fauteuil comprend deux axes de pivotement 36 alignés, un pour chaque montant. The uprights 16.1 and 16.2 can pivot about a pivot axis 36 which extends between two side walls of the box 34 parallel to the rails 32. Alternatively, the chair comprises two pivot axes 36 aligned, one for each amount.

Avantageusement, le plancher 26 comprend au moins une plaque mobile 38 apte à recouvrir le caisson 34. bans une première position, la ou les plaques mobiles 38 sont disposées au niveau des autres plaques du plancher 26 et ferment le caisson 34, comme illustré sur la figure 2. bans une autre position, la ou les plaques mobiles dégagent la face supérieure du caisson 34 ce qui permet au fauteuil de pouvoir être déployé. Selon les cas, la plaque mobile 38 peut être amovible ou coulissante. be préférence, lorsque le fauteuil est en position déployée, la ou les plaques mobiles 38 sont remises en place de manière à refermer le caisson 34, comme illustré sur la figure 6. Advantageously, the floor 26 comprises at least one movable plate 38 able to cover the casing 34. In a first position, the movable plate or plates 38 are arranged at the level of the other plates of the floor 26 and close the casing 34, as illustrated in FIG. Figure 2. In another position, the one or more movable plates release the upper face of the box 34 which allows the chair can be deployed. Depending on the case, the movable plate 38 can be removable or sliding. Preferably, when the chair is in the deployed position, the movable plate or plates 38 are put back in place so as to close the box 34, as shown in Figure 6.

Selon une caractéristique importante de l'invention, les montants 16.1 et 16.2 sont télescopiques de manière à pouvoir loger le fauteuil dans l'espace entre deux traverses 30 consécutives et deux rails 32 consécutifs et plus particulièrement dans le caisson 34 lorsque les montants sont en position rétractée comme illustré sur la figure 4 et offrir une assise à la bonne hauteur lorsque les montants sont en position étendue comme illustré sur les figures 5 et 6. A cet effet, chaque montant comprend deux parties, une partie supérieure 40 à laquelle est reliée l'assise 14 et une partie inférieure 42 apte à pivoter par rapport à la structure porteuse du plancher, les deux parties 40 et 42 pouvant coulisser l'une par rapport à l'autre. Selon un mode de réalisation, la partie supérieure 40 peut se présenter sous la forme d'un élément creux avec un logement de section rectangulaire dans lequel peut coulisser la partie inférieure 42 en forme de plaque. L'invention n'est pas limitée à ce mode de réalisation. Ainsi, les parties 40 et 42 pourraient se présenter sous la forme chacune d'une plaque qui coulissent l'une contre l'autre. Selon un mode de réalisation, pour chaque montant, la partie inférieure 42 comprend au niveau d'une première extrémité un axe de pivotement 36 lui permettant de pivoter par rapport à la structure porteuse, l'autre extrémité de la partie inférieure 42 étant montée coulissante dans la partie inférieure 40 qui comprend elle l'axe de pivotement 18 de l'assise. Avantageusement, le fauteuil 10 comprend des moyens 44 de verrouillage/déverrouillage permettant de maintenir les montants en position étendue. A titre d'exemple, ces moyens 44 comprennent une poignée pivotante susceptible de commander deux tiges en translation, une pour chaque montant. En complément, les parties 40 et 42 comprennent des orifices dont les diamètres sont ajustés à celui des tiges, pour chaque montant, les orifices des deux parties 40 et 42 étant alignés lorsque les montants sont en position étendue. A l'état verrouillé, les tiges traversent via les orifices les deux parties 40 et 42 de manière à les maintenir en position étendue. A l'état déverrouillé, pour chaque montant, la tige ne traverse plus l'orifice de la partie inférieure qui peut alors coulisser dans la partie supérieure. According to an important characteristic of the invention, the uprights 16.1 and 16.2 are telescopic so as to accommodate the chair in the space between two consecutive crosspieces 30 and two consecutive rails 32 and more particularly in the box 34 when the uprights are in position retracted as illustrated in Figure 4 and provide a seat at the right height when the uprights are extended position as shown in Figures 5 and 6. For this purpose, each amount comprises two parts, an upper portion 40 which is connected to seat 14 and a lower portion 42 adapted to pivot relative to the supporting structure of the floor, the two parts 40 and 42 being slidable relative to each other. According to one embodiment, the upper part 40 may be in the form of a hollow element with a rectangular section of housing in which can slide the lower portion 42 in the form of plate. The invention is not limited to this embodiment. Thus, the portions 40 and 42 could be in the form of a plate that slide against each other. According to one embodiment, for each upright, the lower portion 42 comprises at a first end a pivot axis 36 allowing it to pivot relative to the supporting structure, the other end of the lower portion 42 being slidably mounted in the lower part 40 which comprises the pivot axis 18 of the seat. Advantageously, the chair 10 comprises means 44 for locking / unlocking to maintain the uprights extended position. For example, these means 44 comprise a pivoting handle capable of controlling two rods in translation, one for each amount. In addition, the portions 40 and 42 comprise orifices whose diameters are adjusted to that of the rods, for each upright, the orifices of the two parts 40 and 42 being aligned when the uprights are in extended position. In the locked state, the rods pass through the orifices the two parts 40 and 42 so as to maintain them in the extended position. In the unlocked state, for each amount, the rod does not cross the hole of the lower part which can then slide in the upper part.

Bien entendu, l'invention n'est pas limitée à ce mode de réalisation des moyens 44 de verrouillage/déverrouillage. Selon une autre variante non représentée, le châssis peut se limiter à une simple plaque qui peut pivoter par rapport à la structure porteuse et qui est télescopique pour permettre au fauteuil de se loger dans un espace restreint délimité par les renforts du plancher, tout en offrant une assise à une hauteur satisfaisante en position déployée. be manière générale, le châssis comprend au moins un élément télescopique, avec deux parties qui peuvent coulisser l'une par rapport à l'autre, une première partie étant pivotante par rapport au plancher, l'assise étant reliée à l'autre partie de manière pivotante. Le fait que l'élément soit télescopique permet au fauteuil de se loger dans l'espace restreint délimité par les renforts du plancher, tout en offrant une assise à une hauteur satisfaisante en position déployée.
