It should be noted that the others form the seat of the armchair Frame likewise with vertical guides or other alternating connecting means for connecting several adjacent ones Armchairs can be provided.

The cross member 7 connecting the two supports 5 and the lower frame 2 in the rear region 17 of the seat and which connects the backrest 18 carries, for example, is straight. At the junction this -raverse 7 with the beams 5 and 6 oind two essentially vertical feet 20 and 21 attached to the frame, be of the same length and form projections under the frame, to the rear part of the frame at a distance from the To hold ground.

In the example shown, each foot 20 and 21 has the shape a hollow tube such that a substantially vertical guide is formed inside which is suitable from top to bottom at the bottom an adapted pin, for example 22 and 23, which protrudes from the underside of the backrest 18. The backrest can thus be easily removed, for example to make it easier to transport the armchair or to give it a more impression of a real bed when the armchair is unfolded. The two carriers in the front area 19 of the seat and 6 of the lower frame 2 connecting traverse.8 has a strong bulge downward on, ^ as the convenience of the through the seat of the chair according to the invention in the unfolded Condition of educated Betts benefits. In the example shown, the bulge advantageously forms the foot, which the

located in front of the lower frame 2 at a distance from the part The floor which is substantially equal to the height of the rear area. For this purpose, the traverse 8 has three zones 24 to 26, which are straight or substantially straight, with the zones 24 and 26 terminating with the supports 5 and 6 and are firmly attached to them, near theirs front end, and which also assume an inclined position towards the underside of the armchair, where they enter the intermediate zone 25 pass over, which normally rests at least partially on the floor.

In the illustrated preferred embodiment, the Intermediate frame 3, which lies directly above the lower frame 2 in the "armchair position", is designed and made without cross members simply from two girders 2 7 and 28 of equal length, one end of which ends at the corresponding girders 5 and 6 of the lower one Frame 2 at the level of the end of these supports lying in the front region 19 of the seat, in order to switch between one position to be pivotable, in which they over these carriers 5 and 6 (Fig. 1 and 2) and a position in which they are in the extension of one or the other of these carriers (Fig. 4 and 5). An intermediate phase of this bt-turn is shown in Fig. 3, which shows the folding of the armchair to a bed.

Preferably, the hinges 29 and 30, the sichersteilen.derart the connection between the supports 27 and 25 and dU connection between the supports 28 and 6 are formed such that a pivoting of the carrier Ver-27 and 28 over substantially dit

horizontal position in which they are in the extension of the support door 5 and 6, not during the opening movement is possible, which is indicated by the arrow 31 in FIG.

The intermediate frame 3 has no cross members, its rigidity is on the one hand by the lower frame 2 and in particular by its traverse 8 and, on the other hand, through the upper frame 4, which is one of the construction of the lower frame 2 has a similar construction.

Like the lower frame 2, the upper frame 4 is practically formed by two brackets 32 and 33 which are attached to the sides of the seat match and those at both ends through Traverses 34 and 35 are connected analogously to the traverses 8 and 7, respectively.

When viewing the seat in the collapsed position as shown in FIGS. 1 and 2, each bracket 32,33 is of the upper frame 4 at its end corresponding to the rear region 17 of the seat with the end of one of the supports 27 or 28 of the middle frame 3 connected, which also collapsed during this Point the seat position to the rear 17 of the seat.

The articulated connection, which is made for example by hinges 36 and 37 at the level of the supports 32 and 33, respectively, is such provide that the upper frame 4 is pivotable between a position in which its supports 32 and 33 approximately horizontally across the carriers 27 and 28 of the intermediate frame 3 and one

7801920 05/03/78

Position in which they lie in the extension of one or the other of these supports (Fig. 5) · The movement of the frame 4 opposite the frame 3 during the transition from the collapsed Position in this latter position is shown schematically in FIG. 3 by an arrow 38. Preferably the hinges 36 and 37 are designed so that they an opening movement of the upper frame 4 relative to the middle Prevent frame 3 beyond the position in which one frame is an extension of the other.

Likewise, the hinges 36 and 37, as well as the hinges 29 and 30, are preferably designed so that they one Have section that is in the folded position of the chair according to the invention between the superimposed Frame pushes in so that the loads resulting from the weight of the person who may be sitting on the armchair, then not transferred via the hinge axes, but via the sections inserted between the frames.

The traverse 34 of the upper frame 4, which is near the connection this upper frame is arranged with the middle frame 3, agrees with the cross member 8 of the lower frame 2 agree in such a way that on the one hand it forms a foot for the bed formed by the unfolded armchair (FIG. 5), and on the other hand, is firmly connected to the supports 32 and 33, without incurring the rest of the comfort of the armchair in its collapsed or to impair in its unfolded position.

The front cross member 35 can have a structure analogous to that of the cross member 7 and the feet 20 and 21 of the lower frame 2 but it is hidden by a covering of fabric or other material used to draw the armchair is because this traverse 35 closes the seat at its front 19 in the collapsed state.

In Fig. 1 on the one hand and in Figs. 2 and 4 on the other hand bind two ways of forming the padding of the invention Armchairs shown, which can also be used as a mattress after opening the armchair.

In a first embodiment, which is shown in Fig. 1, Verden the upholstery of the backrest and the chair seat through a single cushion element 52 is formed, which is folded into three approximately equal sections 39 to 41, around the backrest cushion and in two superimposed layers' +0 and 41 to form the seat cushion. The section corresponding to the back pad 39 is connected via a fold 42 to the section 40 which, for example, forms the upper layer of the seat cushion, wherein this fold is located in the transition area between the backrest and the seat, on the back of the seat where the Section & 0 connected to section 41 by a fold 43 is formed on the front 19 of the seat.

To make the mattress of the bed, the only padding element is used 52 unfolded, which after its unfolding forms the shape of a rectangle, the length of which is essentially equal to the total

-11-

7801920 05/03/78

length of the three arranged side by side in an extension Frame 2 to 4 is, while the width of this upholstery element 52 corresponds to the seat width of the armchair, such that the side rests of the armchair prevent the mattress from shifting sideways in the unfolded position.

When in Figs. 2 and 4 in folded or unfolded State shown embodiment of the armchair the mattress is formed by two rectangular sections 44 and 45.

The section 44 can be compared to the two sections 40 and 41 of the element 52 of Fig. 1, this section is folded into two substantially equal, superposed sections 46 and 47 to form the seat cushion of the chair, the fold 48 is preferably located on the front 19 of the seat.

While the part 44 has a uniform thickness, like the element 52 shown in Fig. 1, the element 45 shows a first Section 49 of identical thickness in the vicinity of its one edge and a section 50 of greater thickness in the vicinity its other edge parallel to the first edge. In the unfolded position to form a bed, the section 49 becomes more direct Extension of the element 44 arranged and the portion 50 arranged to the rear to form a head cushion. In the folded position into an armchair becomes the section 49 at the top of the backrest and section 50 at the

Connecting pieces arranged between the backrest and the seat, to form a back piece at this height.

Of course, other possible embodiments of the upholstery and mattress design of the armchair according to the invention are possible without to deviate from the spirit of the invention. In particular, one could design the mattress in three separate parts provide. Likewise, the suspension of the armchair and bed upholstery could be done by different means generally extend between the side members of the various frames and sometimes between the end cross members 7 and 35 as well. In the example shown, this suspension is formed by flattened spiral springs 51 known per se, each of which is arranged parallel to the general direction of the crossbars and at one and the other end of two beams of the frame is connected in which it is arranged. One could equally use semi-rigid transverse blades instead of the coil springs connected to the beams or any known device.

Because this suspension or support of the upholstery is exclusively is formed by elements extending in the transverse direction, as shown in the exemplary embodiment, can when folded of the bed in the form of an armchair, the cross member 34 of the upper frame between the support or suspension elements of the middle frame 3 and the lower frame 2 engage.

In certain cases, especially for the purpose of reinforcing them

-13-

7801920 05/03/78

The elements running in the transverse direction can be reinforced by the elements running in the longitudinal direction, these elements being connected to one another. One could also connect the traverse 34 not firmly to the upper frame 4 but to the hinges 36 and 37, which connect the frame 4 to the middle frame 3, wherein in the "bed position" the traverse 34 formed in this way vertically below the hinges 36 and 37 and would stand vertically on the floor below the hinges, thereby preventing the bed from being folded up in an untimely manner, in a case where, for example, its user would sit on one of the stubs 3 or 4 near their joint; In the "armchair position ¹ ", the cross member 34 would insert itself approximately horizontally between the frames 3 and 4, which are then arranged one above the other.

In the exemplary embodiment shown, in which the cross members 8 and 34 are firmly connected to the frames 2 and 4, respectively, these are Traverses inclined to the vertical direction to sit vertically under the joints on the floor, in their Near them are arranged for the same safety reason as mentioned above. This arrangement becomes natural retained for the traverse 8 if the variant explained above is selected for the traverse 34.

The various rigid elements, such as the beams and trusses, the feet and the frames of the elements, such as e.g. B. the backrest, can advantageously be made of round or round cross-section rectangular tubes. When the frame of the
