Description

La présente invention concerne un matelas pour couchette pour un compartiment de moyen de transport de passager. L'invention concerne également une couchette ainsi qu'un véhicule automobile comprenant une telle couchette ou un tel matelas.The present invention relates to a berth mattress for a passenger carrying compartment. The invention also relates to a berth and a motor vehicle comprising such a berth or such a mattress.

Dans le domaine de l'aménagement de cabines, notamment dans les camions de transport routier, les trains ou les bateaux, il est connu d'utiliser des couchettes dont la surface de couchage est variable, afin d'adapter la configuration des cabines à différentes utilisations. Dans le cadre d'une cabine de camion, les conducteurs se reposent dans une partie de leur cabine comprenant une couchette à proximité directe des sièges du conducteur et du passager. La position de ces sièges dans l'habitacle étant réglable, la surface de couchage de la couchette peut être augmentée en poussant les sièges, par exemple contre le tableau de bord. Pour ensuite reprendre son poste de conduite, le conducteur réduit la surface de sa couchette pour pouvoir remettre son siège de conducteur à sa position de conduite.In the field of cabin layout, in particular in road transport trucks, trains or boats, it is known to use berths whose sleeping surface is variable, in order to adapt the configuration of the cabins to different uses. As part of a truck cab, drivers rest in a portion of their cabin including a bunk in the immediate vicinity of the driver's and passenger's seats. The position of these seats in the cabin being adjustable, the sleeping surface of the bunk can be increased by pushing the seats, for example against the dashboard. To then resume his driving position, the driver reduces the surface of his berth to be able to return his driver's seat to his driving position.

A cet effet, des solutions telles que connues de EP-B-1 385 405 , utilisent une couchette composée de plusieurs éléments liés les uns aux autres et offrant chacun une surface de couchage. La surface de couchage de ces couchettes est modifiable en ouvrant ou fermant, par rapport à un élément principal, des tiroirs supportant des éléments additionnels de couchette. Dans une position étendue correspondant à la surface de couchage maximale, les tiroirs des éléments additionnels sont sortis de l'élément principal, et offrent une surface de couchage supplémentaire. Lorsque la surface de couchage doit être réduite, les tiroirs des éléments additionnels sont repoussés contre l'élément principal.For this purpose, solutions as known from EP-B-1 385 405 , use a bunk composed of several elements linked to each other and each offering a sleeping surface. The sleeping surface of these berths is modifiable by opening or closing, with respect to a main element, drawers supporting additional elements of berth. In an extended position corresponding to the maximum sleeping area, the drawers of the additional elements are removed from the main element, and provide an additional sleeping surface. When the sleeping surface needs to be reduced, the drawers of the additional elements are pushed back against the main element.

De telles solutions présentent l'inconvénient d'impliquer une compression des matelas des éléments de couchette additionnels lors de leur repliage contre l'élément principal. Ceci implique qu'en position repliée, les matelas additionnels offrent une surface dure et de ce fait, un inconfort potentiel. De plus, cette solution nécessite un effort physique pour comprimer les matelas additionnels dans leur position repliée.Such solutions have the disadvantage of involving a compression of the mattress additional bunk elements when folding against the main element. This implies that in the folded position, the additional mattresses offer a hard surface and therefore a potential discomfort. In addition, this solution requires a physical effort to compress the additional mattresses in their folded position.

C'est à ces inconvénients qu'entend remédier l'invention en proposant un nouveau matelas dont la structure permet de maintenir un niveau de confort optimal quelle que soit la configuration du matelas, notamment en évitant les inégalités sur la surface disponible pour que l'utilisateur s'installe, et de faciliter les changements de configuration du matelas.It is these drawbacks that the invention intends to remedy by proposing a new mattress whose structure makes it possible to maintain an optimal level of comfort whatever the configuration of the mattress, in particular by avoiding inequalities on the available surface so that the user installs, and facilitate the configuration changes of the mattress.

A cet effet, l'invention concerne un matelas pour une couchette pour un compartiment de moyen de transport de passagers. Ce matelas est caractérisé en ce qu'il comporte :

  • un élément inférieur ayant une surface inférieure d'appui et une surface supérieure oblique formant un angle par rapport à la surface inférieure,
  • un élément supérieur ayant une surface supérieure de couchage et une surface inférieure oblique formant un angle par rapport à la surface supérieure,
    en ce que l'élément supérieur repose par sa surface inférieure oblique sur la surface supérieure oblique de l'élément inférieur,
    et en ce que le matelas comporte au moins deux configurations d'utilisation correspondant à deux positions relatives des deux surfaces obliques, maintenues en contact l'une avec l'autre dans lesquelles :
  • dans une première position, les deux éléments sont entièrement ou substantiellement superposés de manière que le matelas présente une dimension transversale réduite, et une surface supérieure sensiblement plane ;
  • dans une seconde position, les deux éléments sont partiellement décalés transversalement de manière que le matelas présente une dimension transversale augmentée, et une surface supérieure sensiblement plane.
To this end, the invention relates to a mattress for a berth for a compartment of passenger transport means. This mattress is characterized in that it comprises:
  • a lower member having a lower bearing surface and an oblique upper surface forming an angle with respect to the lower surface,
  • an upper member having an upper coating surface and an oblique lower surface forming an angle with respect to the upper surface,
    in that the upper element rests by its oblique lower surface on the oblique upper surface of the lower element,
    and in that the mattress comprises at least two configurations of use corresponding to two relative positions of the two oblique surfaces, maintained in contact with each other in which:
  • in a first position, the two elements are entirely or substantially superimposed so that the mattress has a reduced transverse dimension, and a substantially flat top surface;
  • in a second position, the two elements are partially offset transversely so that the mattress has an increased transverse dimension, and a substantially flat upper surface.

Grâce à l'invention, le matelas autorise une adaptation aux besoins d'un utilisateur, lui permettant d'augmenter facilement la surface totale disponible pour s'étendre sur le matelas. Dans une autre configuration, la surface d'encombrement du matelas peut être réduite afin d'organiser l'espace dans lequel le matelas est installé afin de permettre une utilisation différente de l'espace. La structure du matelas selon l'invention, utilisant le déplacement relatif de deux éléments de matelas, permet de conserver les propriétés de densité des éléments de couchette, et de maintenir un niveau de confort égal dans les deux configurations d'utilisation du matelas, en offrant une surface sensiblement plane, notamment dans la configuration d'utilisation dans laquelle le matelas présente une dimension transversale augmentée.Thanks to the invention, the mattress allows adaptation to the needs of a user, allowing him to easily increase the total area available to extend on the mattress. In another configuration, the space area of the mattress can be reduced to organize the space in which the mattress is installed to allow different use of the space. The structure of the mattress according to the invention, using the relative displacement of two mattress elements, makes it possible to maintain the density properties of the bunk elements, and to maintain an equal level of comfort in the two configurations of use of the mattress, providing a substantially flat surface, especially in the use configuration in which the mattress has an increased transverse dimension.

L'invention concerne également un véhicule de type poids lourd, comportant une cabine dans laquelle sont installés un siège conducteur et un siège passager, ainsi qu'un matelas ou une couchette tels que mentionnés ci-dessus.The invention also relates to a truck type vehicle, comprising a cabin in which are installed a driver's seat and a passenger seat, and a mattress or a berth as mentioned above.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un matelas et d'une couchette conformes au principe de l'invention, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective d'une couchette conforme à l'invention, dans une première configuration ;
  • la figure 2 est une coupe selon le plan Il de la couchette de la figure 1 ;
  • la figure 3 est une vue similaire à la figure 1, dans une deuxième configuration de la couchette selon l'invention ;
  • la figure 4 est une coupe selon le plan IV de la couchette de la figure 3.
The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a mattress and a berth according to the principle of the invention, given only by way of example and with reference to the appended drawings in which:
  • the figure 1 is a perspective view of a berth according to the invention, in a first configuration;
  • the figure 2 is a cut according to the plane II of the berth of the figure 1 ;
  • the figure 3 is a view similar to the figure 1 in a second configuration of the berth according to the invention;
  • the figure 4 is a section on plane IV of the bunk of the figure 3 .

La couchette 2 représentée aux figures 1 à 4 est destinée à être installée dans des compartiments de dimensions réduites, notamment des cabines de camions de transport routier, de trains ou de bateaux.The berth 2 shown in Figures 1 to 4 is intended to be installed in compartments of small dimensions, including cabs of road transport trucks, trains or boats.

En référence à un plancher du compartiment dans laquelle la couchette 2 est installée, on note Z-Z' une direction verticale. En référence à une forme classique parallélépipédique de couchette, on note X-X' une direction longitudinale de la couchette 2, et Y-Y' une direction transversale de la couchette. La direction Y-Y' est perpendiculaire aux directions X-X' et Z-Z' et fait référence à la largeur de la couchette, la direction X-X' faisant référence à la longueur de la couchette 2.With reference to a floor of the compartment in which the bunk 2 is installed, Z-Z 'is noted in a vertical direction. With reference to a conventional parallelepiped bunk shape, X-X 'is a longitudinal direction of the berth 2, and Y-Y' is a transverse direction of the berth. The Y-Y 'direction is perpendicular to the X-X' and Z-Z 'directions and refers to the width of the berth, the X-X' direction referring to the length of the berth 2.

La couchette 2 comporte un premier élément de couchette 100. Ce premier élément de couchette 100 est appelé élément inférieur, en référence à la direction verticale Z-Z'. La couchette 2 comporte un deuxième élément de couchette 200, appelé élément supérieur.The berth 2 comprises a first bunk element 100. This first bunk element 100 is called the lower element, with reference to the vertical direction Z-Z '. The berth 2 comprises a second bunk element 200, called the upper element.

L'élément inférieur 100 comporte un élément inférieur de matelas 102, fixé à un châssis 104. On note respectivement X100, Y100 et Z100 les axes longitudinal, transversal et vertical de l'élément inférieur 100. Le châssis 104 comporte une plaque horizontale 106, sur laquelle est fixée une plaque latérale 108, perpendiculaire à l'axe Y100 et parallèle à l'axe X100. L'élément inférieur de matelas 102 est fixé à la plaque latérale 108 par tout moyen approprié, tel que par collage, par des vis, des rivets, des agrafes, des bandes auto-agripantes de type « Velcro® ». La plaque latérale 108 comporte des moyens de fixation sur une structure porteuse telle que, par exemple, un mur ou une paroi d'une cabine, qui comprennent deux équerres 110. Ces équerres 110 sont munies de lumières de fixation et sont montées avec possibilité de pivotement par rapport à la plaque latérale 108, afin de permettre une rotation de la couchette 2 par rapport à la cabine, parallèlement à sa direction longitudinale X-X'. Cette possibilité de pivotement est prévue notamment pour donner accès à un rangement sous la couchette, et/ou pour amener la couchette 2 dans une position escamotée sensiblement verticale, par exemple le long d'une paroi du compartiment. Dans le cadre d'un véhicule automobile de type poids lourd, la couchette 2 est par exemple fixée contre une paroi arrière de la cabine, avec la direction X-X' de la couchette correspondant à une direction transversale de la cabine. On pourra alors dire que la plaque latérale 108 s'étend sur un bord latéral arrière de la couchette 2.The lower element 100 comprises a lower mattress element 102, fixed to a frame 104. The longitudinal, transverse and vertical axes of the lower element 100 are respectively denoted X100, Y100 and Z100. The frame 104 comprises a horizontal plate 106, on which is fixed a side plate 108, perpendicular to the axis Y100 and parallel to the axis X100. The lower mattress element 102 is fixed to the side plate 108 by any appropriate means, such as by gluing, by screws, rivets, staples, Velcro® type self-gripping strips. The side plate 108 comprises fixing means on a supporting structure such as, for example, a wall or a wall of a cabin, which comprise two brackets 110. These brackets 110 are provided with fixing slots and are mounted with the possibility of pivoting relative to the side plate 108, to allow a rotation of the berth 2 relative to the cabin, parallel to its longitudinal direction X-X '. This possibility of pivoting is provided in particular to give access to a storage under the berth, and / or to bring the berth 2 in a retracted substantially vertical position, for example along a wall of the compartment. In the context of a heavy-duty vehicle, the berth 2 is for example fixed against a rear wall of the cabin, with the direction XX 'of the berth corresponding to a transverse direction from the cabin. It can then be said that the side plate 108 extends on a rear lateral edge of the berth 2.

L'élément inférieur de matelas 102 présente une forme parallélépipédique tronquée par un pan coupé 112 définissant une surface oblique inclinée par rapport à une surface de couchage 114 du matelas 102. Le pan coupé 112 s'étend entre la surface de couchage 114 et une surface inférieure d'appui 116 du matelas 102 et est orienté vers une zone supérieure de la couchette 2. Le pan coupé 112 est parallèle à l'axe longitudinal X100. La surface d'appui 116 rejoint le pan coupé 112 au niveau d'un bord longitudinal 118 commun. De préférence, ce bord longitudinal commun 118 présente une épaisseur verticale la plus faible possible, par exemple inférieure à 30 mm, et préférentiellement inférieure à 15 mm.The lower mattress element 102 has a parallelepipedal shape truncated by a cutaway 112 defining an oblique surface inclined with respect to a coating surface 114 of the mattress 102. The cutaway 112 extends between the coating surface 114 and a surface lower support 116 of the mattress 102 and is oriented towards an upper zone of the berth 2. The cutaway 112 is parallel to the longitudinal axis X100. The bearing surface 116 joins the cutaway 112 at a common longitudinal edge 118. Preferably, this common longitudinal edge 118 has a vertical thickness as small as possible, for example less than 30 mm, and preferably less than 15 mm.

Le deuxième élément de couchette 200 comporte, de la même manière que le premier élément 100, un élément supérieur de matelas 202 et un châssis 204 comportant une plaque horizontale 206 parallèle à l'axe 106 de l'élément inférieur 100. L'élément de matelas 202 de l'élément supérieur 200 présente une forme inversée, selon l'axe vertical Z-Z' de la couchette, par rapport à l'élément de matelas 102 de l'élément inférieur de couchette 100. L'élément supérieur de matelas 202 présente une surface de couchage 208 parallèle à la surface de couchage 114 et de dimensions sensiblement égales à celles de la surface inférieure 116 de l'élément inférieur de matelas 102.The second bunk element 200 comprises, in the same way as the first element 100, a mattress upper element 202 and a frame 204 comprising a horizontal plate 206 parallel to the axis 106 of the lower element 100. mattress 202 of the upper element 200 has an inverted shape, along the vertical axis ZZ 'of the berth, with respect to the mattress element 102 of the lower bunk element 100. The upper element of the mattress 202 has a coating surface 208 parallel to the coating surface 114 and of dimensions substantially equal to those of the lower surface 116 of the lower mattress element 102.

On note respectivement X200, Y200 et Z200 des axes longitudinal, transversal et vertical de l'élément supérieur 200.X200, Y200 and Z200 are respectively denoted as longitudinal, transverse and vertical axes of the upper element 200.

La surface de couchage 114 de l'élément inférieur de matelas 102 a une dimension, selon l'axe transversal Y100, comprise entre 10% et 40%, préférentiellement entre 15% et 30%, de la dimension, selon l'axe transversal Y200, de la surface de couchage 208 de l'élément supérieur de matelas 202.The coating surface 114 of the lower mattress element 102 has a dimension, along the transverse axis Y100, of between 10% and 40%, preferably between 15% and 30%, of the dimension along the transverse axis Y200 of the sleeping surface 208 of the upper mattress element 202.

L'élément supérieur de matelas 202 comporte un pan coupé 210 orienté vers une zone inférieure de la couchette 2 et qui s'étend entre la surface de couchage 208 et un méplat 212 horizontal constituant une surface d'appui, qui est par exemple de dimension sensiblement égale à la surface de couchage 114 de l'élément inférieur de matelas 102. Le pan coupé 210 constitue une surface oblique parallèle à l'axe longitudinal X200, d'aire sensiblement équivalente à l'aire du pan coupé 112 et dont l'angle d'inclinaison par rapport à une direction horizontale est sensiblement égal. Le pan coupé 210 et la surface de couchage 208 se rejoignent en un bord longitudinal 226 commun.The upper mattress element 202 comprises a cutaway 210 oriented towards a lower zone of the berth 2 and which extends between the coating surface 208 and a horizontal flat 212 constituting a bearing surface, which is for example dimensioned substantially equal to the sleeping surface 114 of the lower mattress element 102. The cutaway 210 constitutes an oblique surface parallel to the longitudinal axis X200, of area substantially equivalent to the area of the cutaway 112 and of which the angle of inclination with respect to a horizontal direction is substantially equal. The cutaway 210 and the sleeping surface 208 meet in a common longitudinal edge 226.

L'élément inférieur 100 et l'élément supérieur 200 de la couchette 2 sont reliés l'un à l'autre de manière telle que leurs axes longitudinaux X100 et X200, leurs axes transversaux Y100 et Y200, ainsi que leurs axes verticaux Z100 et Z200 soient parallèles entre eux. Pour cela, la couchette 2 comporte des moyens de liaison entre l'élément inférieur 100 et l'élément supérieur 200.The lower element 100 and the upper element 200 of the berth 2 are connected to each other in such a way that their longitudinal axes X100 and X200, their transverse axes Y100 and Y200, as well as their vertical axes Z100 and Z200. are parallel between them. For this, the berth 2 comprises connection means between the lower element 100 and the upper element 200.

Comme représenté aux figures 2 et 4, une partie du châssis 204 de l'élément supérieur 200 est insérée entre le châssis 104 de l'élément inférieur 100 et la surface inférieure 116 de l'élément de matelas 102 de l'élément inférieur. A l'interface entre les plaques horizontales respectives 106 et 206 des châssis 104 et 204, la couchette 2 comporte des glissières 300, adaptées pour permettre une translation relative des châssis 104 et 204, selon une direction transversale, parallèle à la direction transversale Y-Y' de la couchette 2. Avantageusement, cette couchette 2 comporte deux systèmes de glissières 300, montés de part et d'autre d'une région centrale de la couchette 2, selon sa direction longitudinale X-X'.As represented in figures 2 and 4 a portion of the frame 204 of the upper member 200 is inserted between the frame 104 of the lower member 100 and the lower surface 116 of the mat member 102 of the lower member. At the interface between the respective horizontal plates 106 and 206 of the chassis 104 and 204, the berth 2 comprises slides 300, adapted to allow relative translation of the chassis 104 and 204, in a transverse direction, parallel to the transverse direction YY ' 2. Advantageously, this berth 2 comprises two slide systems 300, mounted on either side of a central region of the berth 2, in its longitudinal direction X-X '.

Les éléments de matelas 102 et 202 des éléments inférieur 100 et supérieur 200 sont mis en place l'un par rapport à l'autre de manière que les pans coupés respectifs 112 et 210 des matelas 102 et 202 soient en contact. Ainsi, les éléments de matelas 102 et 202 sont agencés de façon à être sensiblement symétriques par rapport à un point virtuel situé au centre de la ligne d'interface entre les pans coupés 112 et 210, sur la coupe de la figure 2.The mattress elements 102 and 202 of the lower 100 and upper 200 members are positioned relative to one another so that the respective cut-off faces 112 and 210 of the mattresses 102 and 202 are in contact. Thus, the mattress elements 102 and 202 are arranged to be substantially symmetrical with respect to a virtual point located at the center of the interface line between the cut faces 112 and 210, on the section of the figure 2 .

Les surfaces obliques définies par les pans coupés 112 et 210 des éléments inférieurs et supérieurs de matelas 102 et 202 sont sensiblement planes. L'angle d'inclinaison entre le pan coupé 112 et la surface inférieure 116 de l'élément inférieur 100 est de préférence sensiblement égal à l'angle d'inclinaison entre le pan coupé 210 et la surface de couchage 208 de l'élément supérieur 200. Cet angle d'inclinaison est de préférence inférieur à 25 degrés, par exemple de l'ordre de 15 degrés.The oblique surfaces defined by the cut faces 112 and 210 of the lower and upper elements of the mattresses 102 and 202 are substantially planar. The angle of inclination between the cutaway 112 and the lower surface 116 of the lower member 100 is preferably substantially equal to the angle of inclination between the cutaway 210 and the coating surface 208 of the upper member 200. This angle of inclination is preferably less than 25 degrees, for example of the order of 15 degrees.

L'agencement des éléments de matelas 102 et 202 rend possible un glissement relatif des pans coupés 112 et 210 l'un contre l'autre, selon une direction YG perpendiculaire aux axes longitudinaux X100 et X200 des éléments inférieur 100 et supérieur 200 et inclinée par rapport à la direction horizontale Y-Y' de la couchette 2. Ce glissement relatif est avantageusement facilité par des revêtements anti-frottement recouvrant au moins un des pans coupés 112 et 210, afin que le glissement relatif de ces deux surfaces nécessite un effort raisonnable de l'utilisateur et ne provoque pas de bruits de frottement potentiellement désagréables. Ces revêtements anti-frottement peuvent avantageusement être en un matériau tel que le PTFE.The arrangement of the mattress elements 102 and 202 makes possible a relative sliding of the cut faces 112 and 210 against each other, in a direction YG perpendicular to the longitudinal axes X100 and X200 of the lower elements 100 and upper 200 and inclined by relative to the horizontal direction YY 'of the berth 2. This relative sliding is advantageously facilitated by anti-friction coatings covering at least one of the cut faces 112 and 210, so that the relative sliding of these two surfaces requires a reasonable effort of the user and does not cause potentially unpleasant friction noises. These anti-friction coatings may advantageously be made of a material such as PTFE.

Le châssis 204 de l'élément supérieur 200 comporte une poignée 220, située sur le bord du châssis 204 opposé par rapport à la plaque latérale 108 du châssis 104, comme représenté à la figure 2, soit sur le bord avant dans le cas mentionné plus haut d'une couchette agencée transversalement dans un véhicule automobile. Avantageusement, cette poignée est située dans une région centrale de la couchette 2, selon sa direction longitudinale X-X'. Cette poignée 220 permet à l'utilisateur d'exercer le mouvement de translation relative des plaques 106 et 206 parallèlement aux axes transversaux X100 et X200. La poignée 220 comporte des surfaces d'appui 222 sur un bord latéral 214 de l'élément de matelas 202, permettant d'exercer un effet de poussée sur l'élément de matelas 202 et de servir de butée à l'élément de matelas 202 dans le glissement relatif des pans coupés 112 et 210.The frame 204 of the upper member 200 includes a handle 220, located on the edge of the frame 204 opposite to the side plate 108 of the frame 104, as shown in FIG. figure 2 , or on the front edge in the case mentioned above a bunk arranged transversely in a motor vehicle. advantageously, this handle is located in a central region of the berth 2, according to its longitudinal direction X-X '. This handle 220 allows the user to exert the relative translational movement of the plates 106 and 206 parallel to the transverse axes X100 and X200. The handle 220 has bearing surfaces 222 on a side edge 214 of the mattress member 202, for exerting a pushing effect on the mattress member 202 and serving as a stop for the mattress member 202 in the relative sliding of the cut faces 112 and 210.

L'élément supérieur de matelas 202 est de préférence lié à la partie de châssis 204 de manière à pouvoir se déplacer verticalement selon l'axe Z-Z', tout en suivant les mouvements selon l'axe transversal Y-Y' de cette partie de châssis. Dans l'exemple de réalisation illustré, cette liaison est mise en oeuvre par un élément souple, par exemple une bande de matériau souple 230 visible à la figure 2, reliant la surface inférieure 212 de l'élément supérieur de matelas 202 au bord avant de la partie de châssis 204. Dans la configuration des figures 3 et 4, la bande souple 230 est repliée entre la surface inférieure 212 et la plaque 206 et n'est pas représentée pour la clarté du dessin. La liaison entre l'élément supérieur de matelas 202 et la partie de châssis 204 peut être réalisée par tout autre moyen adapté.The upper mattress element 202 is preferably connected to the frame portion 204 so as to be able to move vertically along the axis Z-Z ', while following the movements along the transverse axis YY' of this frame part. . In the exemplary embodiment illustrated, this connection is implemented by a flexible element, for example a strip of flexible material 230 visible to the figure 2 connecting the bottom surface 212 of the mattress upper member 202 to the front edge of the frame portion 204. figures 3 and 4 , the flexible band 230 is folded between the lower surface 212 and the plate 206 and is not shown for the sake of clarity. The connection between the upper mattress element 202 and the frame portion 204 can be achieved by any other suitable means.

Les éléments inférieur 100 et supérieur 200 de la couchette sont également reliés par l'intermédiaire d'une couche de matériau souple 302 solidaire de la plaque latérale 108 et s'étendant sur la surface de couchage 208 de l'élément supérieur 200. Entre la surface de couchage 208 et la plaque latérale 108, cette couche de matériau forme par exemple un soufflet 304, replié dans la configuration des figures 1 et 2. La couche de matériau souple 302 pourrait alternativement être élastique de manière à s'étirer lors du glissement relatif des pans coupés 112 et 210. Dans la configuration des figures 1 et 2, les éléments inférieur 100 et supérieur 200 de la couchette 2 sont dans une position telle que la surface de couchage 208 de l'élément supérieur est superposée à la surface de couchage 114 de l'élément inférieur 100, c'est-à-dire qu'elle est située, le long de l'axe X-X', à un niveau plus élevé par rapport au niveau de la surface de couchage 114. Dans cette configuration, la surface disponible pour un utilisateur pour prendre place sur la couchette 2 c'est-à-dire la surface supérieure de la couchette 2, comprend uniquement la surface de couchage 208 de l'élément supérieur 200. Cette configuration correspond à une première position relative des pans coupés 112 et 210. De même, cette configuration correspond à une position de la plaque 206 du châssis 204 presque entièrement inséré entre la plaque 106 du châssis 104 et la surface inférieure 116 du matelas 102. Cette configuration offre une largeur de couchette réduite, adaptée au besoin d'un encombrement faible dans une cabine de taille réduite, notamment dans le cas où l'agencement de la cabine en question doit être modifié pour une activité nécessitant plus de place. Dans cette position, la largeur de la couchette est adaptée pour servir d'assise de banquette.The lower and upper elements 200 of the berth are also connected via a layer of flexible material 302 integral with the side plate 108 and extending over the coating surface 208 of the upper element 200. coating surface 208 and the side plate 108, this layer of material forms for example a bellows 304, folded in the configuration of the figures 1 and 2 . The layer of flexible material 302 could alternatively be elastic so as to stretch during the relative sliding of the cut faces 112 and 210. In the configuration of the figures 1 and 2 , the lower and upper elements 200 100 of the berth 2 are in a position such that the coating surface 208 of the upper element is superimposed on the coating surface 114 of the lower element 100, that is to say it is located, along the X-X 'axis, at a higher level relative to the level of the sleeping surface 114. In this configuration, the surface available for a user to take place on the berth 2 that is to say the upper surface of the berth 2, comprises only the coating surface 208 of the upper member 200. This configuration corresponds to a first relative position of the cut faces 112 and 210. Similarly, this configuration corresponds at a position of the plate 206 of the frame 204 almost entirely inserted between the plate 106 of the frame 104 and the lower surface 116 of the mattress 102. This configuration offers a reduced berth width, adapted to the need for a space requirement. in a small cabin, especially where the layout of the cabin in question must be modified for an activity requiring more space. In this position, the width of the berth is adapted to serve as a bench seat.

Pour augmenter la largeur de la couchette, un utilisateur peut exercer, à l'aide de la poignée 220, un mouvement de translation selon la flèche F1 à la figure 1, afin d'éloigner la poignée 220 par rapport à la plaque latérale 108. Lors d'un tel mouvement de translation, les châssis 104 et 204 subissent un mouvement de translation relatif permis par les glissières 300 et tendant à faire sortir une partie plus importante de la plaque 206 par rapport au matelas 102 et à la plaque 106.To increase the width of the berth, a user can exert, using the handle 220, a translational movement along the arrow F1 to the figure 1 , in order to move the handle 220 relative to the side plate 108. During such a translational movement, the frames 104 and 204 undergo a relative translational movement allowed by the slides 300 and tending to extract a larger part of the plate 206 relative to the mattress 102 and to the plate 106.

Cette translation relative des châssis 104 et 204 a pour effet d'autoriser le glissement relatif au niveau des pans coupés 112 et 210, l'élément supérieur de matelas 202 subissant donc un glissement selon la flèche F2 à la figure 1. Lors du glissement de l'élément supérieur de matelas 202, la surface de couchage 208 subit un déplacement tendant à la rapprocher, selon une direction verticale, de la surface de couchage 114 de l'élément inférieur 100.This relative translation of the frames 104 and 204 has the effect of allowing relative sliding at the level of the cut faces 112 and 210, the upper element of the mattress 202 thus undergoing a sliding according to the arrow F2 at the figure 1 . During the sliding of the upper mattress element 202, the coating surface 208 undergoes a movement tending to bring it, in a vertical direction, to the coating surface 114 of the lower element 100.

Lorsque la translation relative des châssis 104 et 204 se termine, les surfaces de couchage 208 et 114 sont en affleurement l'une de l'autre comme représenté aux figures 3 et 4. Dans cette configuration, la surface disponible pour un utilisateur pour prendre place sur la couchette 2, c'est-à-dire la surface supérieure de la couchette 2, est une surface dont la partie centrale est sensiblement plane, créée par l'affleurement des surfaces de couchage 208 et 114. Dans cette position, le soufflet 304 est déployé sur la surface du couchage 114 et un utilisateur dispose d'une surface augmentée proportionnellement à la dimension transversale de la surface de couchage 114 pour s'étendre sur la couchette 2. La partie centrale de la surface supérieure de la couchette 2 ne présente aucune dépression ou différence d'inclinaison ou de niveau dans cette configuration. L'épaisseur totale E2 de la couchette 2, mesurée verticalement entre la surface de couchage 208 et la surface inférieure 116, est, dans cette configuration, sensiblement constante sur toute la largeur de la couchette. Ceci permet à l'utilisateur de bénéficier d'un confort optimal lorsqu'il s'étend sur la couchette 2 car la portance du matelas est constante sur toute la largeur. Les revêtements anti-frottement recouvrant les pans coupés 112 et 210 permettent, dans cette configuration, d'éviter des bruits de frottement désagréables qui pourraient être causés par les mouvements de l'utilisateur sur la couchette.When the relative translation of the frames 104 and 204 ends, the coating surfaces 208 and 114 are flush with each other as shown in FIGS. figures 3 and 4 . In this configuration, the surface available for a user to seat on the berth 2, that is to say the upper surface of the berth 2, is a surface whose central portion is substantially flat, created by the outcrop of In this position, the bellows 304 is deployed on the surface of the coating 114 and a user has an increased surface proportionally to the transverse dimension of the sleeping surface 114 to extend on the berth 2 The central portion of the upper surface of the berth 2 has no depression or difference in inclination or level in this configuration. The total thickness E2 of the berth 2, measured vertically between the coating surface 208 and the lower surface 116, is, in this configuration, substantially constant over the entire width of the berth. This allows the user to enjoy optimal comfort when it extends over the berth 2 because the capacity of the mattress is constant over the entire width. The anti-friction coatings covering the cut sides 112 and 210 allow, in this configuration, to avoid unpleasant friction noises that could be caused by the movements of the user on the berth.

Dans le cas où l'utilisateur décide, par exemple, de se remettre à son poste de conduite, il exerce, par l'intermédiaire de la poignée 220, un effort selon la flèche F3, parallèlement à la direction transversale Y-Y' de la couchette 2, tendant à repousser l'élément supérieur 200 en direction de la plaque latérale 108 de l'élément inférieur 100. Un tel mouvement a pour effet d'induire un glissement relatif des pans coupés 112 et 210 et un déplacement de l'élément supérieur 200, par rapport à l'élément inférieur 100, selon la flèche F4 à la figure 3. Ce déplacement tend à ramener la couchette 2 dans la configuration des figures 1 et 2.In the case where the user decides, for example, to return to his driving position, he exerts, through the handle 220, a force along arrow F3, parallel to the transverse direction YY 'of the berth 2, tending to repel the upper member 200 towards the side plate 108 of the lower member 100. Such a movement has the effect of inducing a relative sliding of the cut faces 112 and 210 and a displacement of the upper member 200, compared to the lower element 100, according to the arrow F4 at the figure 3 . This displacement tends to bring the berth 2 back into the configuration of the figures 1 and 2 .

Lorsque le mouvement de translation initié par l'utilisateur selon la flèche F3 se termine, la surface de couchage 208 de l'élément supérieur 200 est de nouveau superposée à la surface du couchage 114 de l'élément inférieur 100. Le soufflet 304 est de nouveau replié, et l'épaisseur totale E1, mesurée de la même façon que l'épaisseur E2, de la couchette 2 est supérieure à l'épaisseur E2 de la couchette dans la configuration étendue.When the translation movement initiated by the user according to the arrow F3 ends, the coating surface 208 of the upper element 200 is again superimposed on the surface of the coating 114 of the lower element 100. The bellows 304 is of again folded, and the total thickness E1, measured in the same way as the thickness E2, of the berth 2 is greater than the thickness E2 of the berth in the extended configuration.

La configuration de la couchette 2 représentée aux figures 1 et 2 est particulièrement adaptée à la position assise d'un utilisateur, dans la mesure où l'épaisseur augmentée de la couchette 2 permet de supporter un poids plus important, correspondant à la concentration de la masse de l'utilisateur sur une surface plus réduite dans la position assise que dans la position couchée. De ce fait, la structure de la couchette 2 offre donc un niveau de confort optimal dans la configuration d'assise et dans la configuration étendue. Afin de garantir ce confort, les matelas 202 et 102 peuvent avantageusement comprendre des parties en mousse polyuréthane. Les dimensions de la poignée 220 sont suffisamment réduites, selon l'axe Y200, pour ne pas gêner l'utilisateur lorsque celui-ci s'assoit sur la couchette 2 en configuration d'assise. Le passage d'une configuration à l'autre se fait uniquement par glissement des éléments l'un contre l'autre et ne fait intervenir aucune modification des dimensions ou des caractéristiques de densité des matelas 102 et 202.The configuration of the berth 2 shown in figures 1 and 2 is particularly adapted to the sitting position of a user, since the increased thickness of the berth 2 makes it possible to support a greater weight, corresponding to the concentration of the mass of the user on a smaller surface in the sitting only in the supine position. As a result, the structure of the berth 2 thus offers an optimal level of comfort in the seat configuration and in the extended configuration. In order to guarantee this comfort, the mattresses 202 and 102 may advantageously comprise polyurethane foam parts. The dimensions of the handle 220 are sufficiently reduced, along the axis Y200, to not interfere with the user when it sits on the berth 2 in seat configuration. The passage from one configuration to another is only by sliding the elements against each other and does not involve any change in the dimensions or density characteristics of the mattresses 102 and 202.

Le méplat 212 de l'élément supérieur 200, symétrique par rapport à la surface de couchage 114 de l'élément inférieur 100, permet de conférer à la couchette 2 une bonne compacité dans sa direction verticale Z-Z'. En effet, lorsque la couchette 2 est en configuration étendue, aucune partie de l'élément supérieur 200 ne s'étend au-delà du châssis 104 de l'élément inférieur 100. Ceci permet d'optimiser l'agencement de la cabine dans laquelle la couchette est installée, notamment en prévoyant un espace de rangement, tel qu'un coffre, sous la couchette 2 et accessible en soulevant la couchette.The flat 212 of the upper element 200, symmetrical with respect to the coating surface 114 of the lower element 100, makes it possible to give the berth 2 good compactness in its vertical direction Z-Z '. Indeed, when the berth 2 is in the extended configuration, no part of the upper element 200 extends beyond the chassis 104 of the lower element 100. This optimizes the arrangement of the cabin in which the bunk is installed, including providing a storage space, such as a trunk, under the bunk 2 and accessible by lifting the berth.

Comme représenté aux figures 1 et 3, l'élément supérieur 200 présente un épaulement intérieur 224 permettant de ménager un espace dans lequel un siège de conducteur d'une cabine de camion peut notamment se positionner. L'utilisateur utilisera de préférence la zone près de laquelle l'épaulement 124 est pratiqué pour placer ses pieds lorsqu'il s'étend sur la couchette 2. Un épaulement similaire peut également être prévu à l'autre extrémité de la couchette 2. L'épaulement 224 ne s'étend pas sur la zone centrale où la poignée 220 est située, ce qui permet à l'utilisateur de disposer d'une surface plus large pour le tronc, notamment des épaules au bassin, lorsqu'il est allongé sur la couchette 2.As represented in figures 1 and 3 , the upper member 200 has an inner shoulder 224 for providing a space in which a driver's seat of a truck cab can in particular be positioned. The user will preferably use the area near which the shoulder 124 is practiced to place his feet when he extends over the berth 2. A similar shoulder may also be provided at the other end of the berth 2. The shoulder 224 does not extend over the central area where the handle 220 is located, which allows the user to have a wider surface for the trunk, including shoulders to the pelvis, when lying on the berth 2.

Selon une variante non représentée, la couchette 2 peut comprendre des moyens de verrouillage d'une ou plusieurs configurations de la couchette. Les moyens peuvent par exemple comporter un loquet mécanique, ou un système d'indexage installé sur les glissières 300.According to a variant not shown, the berth 2 may comprise locking means of one or more configurations of the berth. The means may for example comprise a mechanical latch, or an indexing system installed on the slides 300.

En l'absence de tels moyens, les forces de frottement liées aux glissières 300 et liées au contact des surfaces obliques des éléments de matelas peuvent suffire à maintenir les éléments 100 et 200 dans leurs positions relatives respectives.In the absence of such means, the frictional forces associated with the slides 300 and related to the contact of the oblique surfaces of the mattress elements may be sufficient to maintain the elements 100 and 200 in their respective relative positions.

Selon un mode de réalisation de l'invention qui n'est pas représenté sur les figures, la couchette peut être réduite à un simple matelas séparé en deux parties inférieure et supérieure constituées respectivement par les matelas 102 et 202. Dans un tel cas, les deux parties de matelas peuvent être solidarisées par des moyens tels des bandes auto-agrippantes au niveau des pans coupés 112 et 210. Le passage entre les deux configurations d'utilisation se fait alors par la désolidarisation des parties 102 et 202, puis par la solidarisation des deux parties dans l'autre positionnement relatif des pans coupés 112 et 210.According to one embodiment of the invention which is not shown in the figures, the berth can be reduced to a simple separate mattress into two lower and upper parts constituted respectively by the mattresses 102 and 202. In such a case, the two mattress parts can be secured by means such as self-gripping strips at the cut faces 112 and 210. The passage between the two configurations of use is then by the separation of the parts 102 and 202, then by the joining together of the two parts in the other relative positioning of the cut faces 112 and 210.

Selon un autre mode de réalisation qui n'est pas représenté sur les figures, l'un au moins des matelas 102 et 202 présente, dans un plan perpendiculaire à la direction transversale X-X', une section triangulaire et ne comportent pas les surfaces 114 ou 212. Dans le cas de l'élément inférieur 100 ayant une telle section triangulaire, la partie supérieure de l'élément inférieur 100 joue le rôle de rebord anti-chute en saillie de la surface de couchage 208 en configuration étendue. Les moyens de fixation 110 par rapport à une structure porteuse sont avantageusement placés du côté de l'élément supérieur 200, correspondant à la partie gauche des figures 2 et 4.According to another embodiment which is not shown in the figures, at least one of the mattresses 102 and 202 has, in a plane perpendicular to the transverse direction X-X ', a triangular section and does not have the surfaces 114 or 212. In the case of the lower member 100 having such a triangular section, the upper portion of the lower member 100 acts as a falling edge protruding from the coating surface 208 in extended configuration. The fixing means 110 with respect to a supporting structure are advantageously placed on the side of the upper element 200, corresponding to the left part of the figures 2 and 4 .

Les caractéristiques des différents modes de réalisation décrits peuvent être combinées dans le cadre de la présente invention. Dans le cas ou l'invention consiste en un matelas, la surface supérieure de ce matelas présente une partie centrale sensiblement plane dans la seconde configuration d'utilisation, grâce à l'affleurement des surfaces de couchage 208 et 114.The characteristics of the various embodiments described can be combined in the context of the present invention. In the case where the invention consists of a mattress, the upper surface of this mattress has a substantially flat central portion in the second configuration of use, thanks to the outcropping of the coating surfaces 208 and 114.
