- the seat mattress which protrudes in front of the seat frame in the seat position, so as not to interfere with the legs of the seated person above, is pulled back to the bed position.
- the seat mattress is thus automatically refocused on the seat frame, so as to overlap it less than in the seat position.
- the furniture according to the invention accommodates seat and back frames with traditional articulation and prevents the mattresses from having to be fixed permanently to their associated frame.

- the seat mattress has a rectangular transverse profile and the second connection is located in the area of the rear lower corner of the seat mattress;
- the second link is of the type attaching to hook-and-loop or self-adhesive strips to one another; - the cooperating parts connected to each other of the bands are located, at least in the seat position, behind the back frame;
- the first link is located on the upper faces of the seat and back mattresses, away from the seat and back frames;
- the first link connects between them the rear upper transverse end of the seat mattress and the upper front transverse end of the back mattress, distant from the seat and back frames, and adjacent to each other in bed position;
- the seat mattress has an upper face remote from a lower face facing the seat frame and the frame respectively backrest, the first link comprising a fastener connecting the upper front end of the back mattress to at least one attachment point on the upper face of the seat mattress, located at a determined distance in front of the rear upper end of the mattress of seat, the transverse length of the fastener of the first connection between the seat mattress and the back mattress being greater than or equal to the distance between the point of attachment of the fastener of the first connection to the mattress seat and the upper rear end of the seat mattress;
- the attachment point of the attachment of the first connection to the seat mattress is located at a determined distance in front of the rear upper end of the seat mattress, less than the thickness of the back mattress taken perpendicularly to its upper and lower faces.
- FIG. 1 is a schematic side view of a piece of furniture according to the invention in the seat position
- FIG. 2 is an enlarged schematic view of the cabinet according to Figure 1;
- FIG. 3 is a schematic side view of the furniture according to the invention in an intermediate position taken during the passage between one and the other of the seat and bed positions;
- FIG. 4 is a schematic side view of the furniture according to the invention in bed position;
- FIG. 5 is an enlarged schematic view of the cabinet according to Figure 3;
- FIG. 6 is a schematic perspective view of the furniture according to the invention in the seat position.
- FIG. 7 is a schematic top view of the frames of the furniture according to the invention.
- the furniture according to the invention comprises a base or lower support structure 1 comprising feet 2 for supporting the ground.
- the frame 1 may include, as is known, side armrests, which are however not shown in the figures.
- a bed base 3 comprising a seat frame 4 and a file frame 5 comprising a hinge 6 between them, directed in the lateral direction Y or 16 in FIG. 7.
- the articulation 6 between the frames 4 and 5 is of the type known under the click-clack and comprises a seat position, in which the frame 5 of the backrest is locked in a raised position relative to the frame 4 of the seat, making a obtuse angle determined rearward therewith, as shown in Figures 1, 2 and
- the transition from the seat position to the bed position takes place in the plane XZ transverse to the articulation 6, by first tilting the frames 4 and 5 back while keeping their obtuse angle , so that the back frame 5 is found horizontally on the base 1 and the seat frame 4 is in the raised position forward, as shown in Figure 3, then folding forward and down the seat frame 4 on the base 1 horizontally in the direction of the arrow indicated in Figure 3, to the bed position.
- the transition from the bed position to the seat position is carried out by performing these operations in the opposite direction in the plane XZ transverse to the joint 6.
- the seat and backrest frames 4 are arranged respectively a seat mattress 7 and a backrest mattress 8, 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 remote from the back mattress 8 and from the articulation 6, the direction going from the 'front to back defining the direction in which a person leans against the backrest mattress 8 in the seat position.
- the seat mattress 7 has a first connection 12 with the back mattress 8 and a second connection 13 with the back frame 5.
- the first link 12 is located on the upper parts of the mattresses
- the mattresses 7 and 8 are of rectangular cross section in the transverse plane XZ and each have an upper face 17, 18 remote from a lower face 19, 20 facing respectively the seat frame 4, and towards the back frame 5.
- the mattresses 7, 8 and the piece of furniture are asymmetrical, 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 to be long relative to the mattress 8.
- the seat frame 4 has a length of about 65 centimeters, while the back frame 5 has a length of about 55 centimeters. Consequently, in the seat position, the seat mattress 7 exceeds 10 centimeters at the front approximately of the frame 4.
- the seat and back mattresses can be of equal length.
- the upper and lower faces 17, 19 of the seat mattress 7 are connected transversely to one another by their rear end 10 in the form of a substantially planar face, while the upper and lower faces 18, 20 of the back mattress 8 are connected transversely between they near the mattress 7 by a front face 21.
- the first link 12 includes 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 mattress 7 seated.
- the fastener 22 is for example formed by a band sewn onto the mattresses 7 and 8.
- 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 preceding dimensions are determined so that this length L3 of the seat mattress 7 offered for support, which is that taken up to the back mattress 8, is less than or equal to the length L2 of the back mattress 8.
- 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 sewing edges 23 and 24, or others.
- 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.
- 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 rear lower corner 25 of the seat mattress 7 joining the faces 19 and 10.
- the second link 13 connects the seat mattress 7 to a part 30 of the back frame 5 located at a distance from the articulation 6 between the seat frame 4 and the back frame 5.
