Sur les cadres 4 d'assise et 5 de dossier vent disposes respectivement un matelas 7 d'assise et un matelas 8 de dossier, les cadres 4, 5 comportant respectivement des lattes 14, 15 de support des matelas a cet effet. Les matelas 7, 8 vent disposes de maniere a pouvoir coulisser librement transversalement sur les cadres 4, 5. Le matelas 7 d'assise comporte une extremite avant 9 eloignee du matelas 8 de dossier et de ['articulation 6, le sens allant de ['avant vers l'arriere definissant le sens dans lequel une personne s'appuie contre le matelas 8 de On the frames 4 of the seat and 5 of the wind backrest respectively disposed a mattress 7 of the seat and a mattress 8 of the backrest, the frames 4, 5 respectively comprising slats 14, 15 for supporting the mattresses for this purpose. The mattresses 7, 8 are arranged so that they can slide freely transversely on the frames 4, 5. The seat mattress 7 has a front end 9 away from the mattress 8 of the backrest and the articulation 6, the direction going from [ forward towards the rear defining the direction in which a person leans against the mattress 8 of

Le matelas 7 d'assise comporte une premiere liaison 12 avec le The seat mattress 7 has a first connection 12 with the
matelas 8 de dossier et une deuxieme liaison 13 avec le cadre 5 de dossier. backrest mattress 8 and a second connection 13 with the backrest frame 5.
La premiere liaison 12 est situee sur les parties superieures des matelas The first link 12 is located on the upper parts of the mattresses
7, 8, eloignees des cadres 4, 5.7, 8, away from the frames 4, 5.
Ainsi que represente aux figures, les matelas 7 et 8 vent de section transversale rectangulaire dans le plan transversal XZ et comportent chacun une face superieure 17, 18 eloignee d'une face inferieure 19, 20 tournee respectivement As shown in the figures, the mattresses 7 and 8 wind of rectangular cross section in the transverse plane XZ and each have an upper face 17, 18 away from a lower face 19, 20 respectively rotated
vers le cadre d'assise 4, et vers le cadre de dossier 5. towards the seat frame 4, and towards the back frame 5.
Les matelas 7, 8 et le mouble vent asymetriques, le matelas 7 d'assise ayant une longueur L1, le long de sa face superieure 17, superieure a la longueur L2 du matelas 8 de dossier le long de sa face superieure 18 et etant dit long par rapport au matelas 8. Par exemple, on utilise un matelas 7 d'assise de iongueur L1 egale a 75 centimetres environ ou plus et un matelas 8 de dossier de longueur L2 egale a 55 centimetres environ ou moins, la longueur totale des matelas 7, 8 en position lit etant egale par exemple a L1+L2 = 130 centimetres. Le cadre 4 d'assise presente une longueur de 65 centimetres environ, tandis que le cadre 5 de dossier presente une longueur de 55 centimetres environ. Par consequent, en position siege, le matelas 7 d'assise depasse de 10 centimetres a ['avant environ du cadre 4. Bien entendu, la longueur totale des matelas pourrait egalement etre choisie The asymmetric mattresses 7, 8 and the wind blast, the seat mattress 7 having a length L1, along its upper face 17, greater than the length L2 of the back mattress 8 along its upper face 18 and being said long with respect to mattress 8. For example, a seat mattress 7 of length L1 equal to approximately 75 centimeters or more and a backrest mattress 8 of length L2 equal to approximately 55 centimeters or less is used, the total length of the mattresses 7, 8 in the bed position being equal for example to L1 + L2 = 130 centimeters. The seat frame 4 has a length of approximately 65 centimeters, while the back frame 5 has a length of approximately 55 centimeters. Consequently, in the seat position, the seat mattress 7 exceeds by 10 centimeters at about the front of the frame 4. Of course, the total length of the mattresses could also be chosen.
egale par exemple a L1 +L2 = 140 centimetres ou autres. equal for example to L1 + L2 = 140 centimeters or others.

En position lit, les faces 10 et 21 des matelas 7, 8 vent cote a cote. In the bed position, the faces 10 and 21 of the mattresses 7, 8 wind side by side.
Aux figures, la premiere liaison 12 comporte une attache 22 reliant ltextremite des faces superieures et avant 18, 21 du matelas 8 de dossier a un point 23 de fixation a la face superieure 17 du matelas 7 d'assise, le point 23 etant situe a une distance determinee en avant de la face 20 arriere du matelas 7 d'assise, inferieure a l'bpaisseur du matelas 8 de dossier prise perpendiculairement a ses faces superieure et inferieure 18, 20. La longueur transversale de ['attache 22 est superieure ou egale, par exemple legerement superieure a, la distance sur la face superieure 17 du matelas 7 d'assise entre le point 23 de fixation de ['attache et l'arete 26 la reliant a la face arriere 20 du matelas 7 d'assise. L'attache 22 est par In the figures, the first link 12 comprises a fastener 22 connecting the end of the upper and front faces 18, 21 of the back mattress 8 to a point 23 of attachment to the upper face 17 of the seat mattress 7, point 23 being located at a determined distance in front of the rear face 20 of the seat mattress 7, less than the thickness of the back mattress 8 taken perpendicular to its upper and lower faces 18, 20. The transverse length of the fastener 22 is greater than or Equal, for example slightly greater than, the distance on the upper face 17 of the seat mattress 7 between the point 23 of attachment of the fastener and the edge 26 connecting it to the rear face 20 of the seat mattress 7. Attachment 22 is by

Ainsi, en position siege, le matelas 8 de dossier est-il en appui partiel par sa face avant 21 sur le matelas 7 d'assise, ce qui permet avantageusement de reduire la longueur L3 du matelas 7 d'assise offerte a l'appui d'un etre humain sur sa face superieure 17 en position siege. Les dimensionnements precedents vent determines de telle sorte que cette longueur L3 du matelas 7 d'assise offerte a l'appui, qui est celle prise jusqu'au matelas 8 de dossier, soit inferieure ou egale a Thus, in the seat position, the backrest mattress 8 is partially supported by its front face 21 on the seat mattress 7, which advantageously makes it possible to reduce the length L3 of the seat mattress 7 offered for support of a human being on its upper face 17 in the seat position. The previous dimensions are determined so that this length L3 of the mattress 7 of the seat offered for support, which is that taken up to the mattress 8 of the backrest, is less than or equal to
la longueur L2 du matelas 8 de dossier. the length L2 of the backrest mattress 8.
Dans une variante non representee, la premiere liaison 12 relic directement entre elles l'arete 26 du matelas 7 d'assise a l'arete 24 du matelas 8 de dossier, reliant sa face superieure 18 et sa face avant 21, par exemple par une In a variant not shown, the first link 12 directly connects the edge 26 of the seat mattress 7 to the edge 24 of the back mattress 8, connecting its upper face 18 and its front face 21, for example by a
couture des aretes 23 et 24, ou autres. stitching edges 23 and 24, or others.
La deuxieme liaison 13 est situee sur le cote du matelas 7 d'assise, situe a proximite du cadre 5 de dossier et du cadre 4 d'assise. Par exemple, ainsi que represente, la deuxieme liaison 13 est situee sur la face inferieure 19 du matelas 7 ou sur sa face arriere 10, ou, ainsi que represente, sur le coin inferieur arriere 25 du The second link 13 is located on the side of the seat mattress 7, located near the back frame 5 and the seat frame 4. For example, as shown, the second link 13 is located on the lower face 19 of the mattress 7 or on its rear face 10, or, as shown, on the lower rear corner 25 of the
matelas 7 d'assise joignant les faces 19 et 10. seat mattress 7 joining the faces 19 and 10.
La deuxieme liaison 13 relic le matelas 7 d'assise a une partie 30 du cadre 5 de dossier situee a distance de ['articulation 6 entre le cadre 4 d'assise et le cadre 5 de dossier. La partie 30 est par exemple formee par une barre dirigee suivant la direction laterale Y du cadre 5, par exemple celle sur laquelle vent The second link 13 connects the seat mattress 7 to a part 30 of the back frame 5 located at a distance from the hinge 6 between the seat frame 4 and the back frame 5. The part 30 is for example formed by a bar directed in the lateral direction Y of the frame 5, for example that on which wind

Lorsqutil est passe de la position siege a la position lit, le deplacement du cadre 4 d'assise et du cadre 5 de dossier vers la position plane, ainsi que represente par la fleche a la figure 3, tire transversalement le matelas 7 d'assise vers l'arriere. Ainsi, I'extremite avant 9 du matelas 7 d'assise, qui depassait du cadre 4 d'assise en position siege est-elle ramenee vers l'arriere en position lit, ainsi que represente a la figure 4. Par suite de ce deplacement vers l'arriere, I'extremite avant 9 est par exemple sensiblement alignee avec l'extremite avant 34 du cadre 4 d'assise, de meme que l'extremite arriere 35 du cadre 5 de dossier avec l'extremite arriere 36 du matelas 8. Le basculement du matelas 7 d'assise en position lit a partir de la position intermediaire de la figure 3 fait en meme temps avancer, par l'intermediaire de la premiere liaison 12 le matelas 8 de dossier sur le cadre 5 de dossier. II est ainsi obtenu un bon positionnement des matelas 7 et 8 sur les cadres 4 et 5 en position lit. II est ainsi assure que le matelas d'assise 7 ne depasse pas du cadre 4 en position lit. Bien entendu, il peut etre prevu une ou plusieurs deuxieme liaison 13 entre le matelas 7 et le cadre 5, aligne suivant l'axe Y. comme When it has moved from the seat position to the bed position, the displacement of the seat frame 4 and the back frame 5 towards the flat position, as represented by the arrow in FIG. 3, transversely pulls the seat mattress 7 rearward. Thus, the front end 9 of the seat mattress 7, which protruded from the seat frame 4 in the seat position, is it brought back towards the rear in the bed position, as shown in FIG. 4. As a result of this displacement towards the rear, the front end 9 is for example substantially aligned with the front end 34 of the seat frame 4, as well as the rear end 35 of the back frame 5 with the rear end 36 of the mattress 8 The tilting of the seat mattress 7 in the bed position from the intermediate position in FIG. 3 simultaneously advances, through the first connection 12, the backrest mattress 8 on the backrest frame 5. A good positioning of the mattresses 7 and 8 is thus obtained on the frames 4 and 5 in the bed position. It is thus ensured that the seat mattress 7 does not exceed the frame 4 in the bed position. Of course, one or more second connections 13 can be provided between the mattress 7 and the frame 5, aligned along the axis Y. as
par exemple trots liaisons 13 selon la figure 7, ou deux liaisons 13 selon la figure 6. for example trots connections 13 according to FIG. 7, or two connections 13 according to FIG. 6.
