Seating furniture that can be folded into a bed

The present innovation relates to a piece of furniture that can be folded up to form a bed, preferably an armchair or a sofa, with a back part pivotably connected to a backrest part, a seat part and a horizontally movable bed box arranged under the seat part, the seat part and the The backrest part are laterally connected to each other in a foldable manner by an adjustment fitting.

The innovation provides that each adjustment fitting is articulated with a limited pivoting on the bed box connected strap is connected, which in the sitting position of the chair in the direction of the backrest part and in the unfolded position of the chair in the direction of the seat part.

This ensures that when you open the chair, the distance between the backrest part and the seat part remains unchanged, so that

can constantly touch the two parts without forming a gap.

This is particularly advantageous insofar as the individual upholstery parts now come together with a piece of polystyrene can be related, which is absolutely desirable, as this does not allow dirt to permeate Areas yield more.

A particularly simple and effective limitation of the pivoting movement of the bracket is through another Given an advantageous embodiment in which the tab on its end associated with the bed box has ring segment-shaped elongated hole in which a stop bolt connected to the bed box is guided, so that the pivoting movement of the tab is only possible within the limits given by the elongated hole.

If now in combination with this embodiment of the innovation of the adjustment fitting, as after another Innovation according to the design of the chair provided, designed as a known scissor fitting is, the flap with its end facing away from the bed box with a pivot lever of the scissor fitting is connected, can easily speak of an optimal adjustment and pivoting option become, especially if, as a further idea of the innovation provides, a tension spring on the one hand is fixed on the tab and on the other hand to the stop bolt, so that due to the tension spring force Pivoting movement of the tab inevitably takes place.

and 5 an adjustment fitting with a tab designed according to the invention in different positions of the seating furniture.

In Figs. 1 to 3, a piece of furniture is shown, which in its basic structure consists of a bed frame 11, a Seat part 1, a backrest part 2, a back part 3 and one arranged below the seat part 1 and horizontally movable bed box 4 located in the area of the bed frame 11 in the seated position of the chair.

The backrest part 2 and the seat part 1 are provided with an adjustment fitting 5 designed as a scissor fitting hingedly connected to one another, while a tab 6 is fixed on the one hand to the bed box 4 so as to be pivotable to a limited extent and on the other hand with a pivot lever 9 of the adjustment fitting 5, which is very clearly shown in FIGS can be seen is articulated.

In Fig. 1, the seating furniture is shown in a sitting position in which the back part 3 remains unused and behind the backrest part 2, the rear side of which is folded back to cover it.

The bed box 4 is located in the area formed by the bed frame 11. The tab 6 has in this position of the chair in the direction of the backrest part 2, while in the FIG The position of the situs in the direction of the Seat part 1 has.

From Fig. 2, the various pivot positions of the seat part 1 can be seen with which the seating furniture is folded into a horizontal lying position.

On the basis of these illustrated different pivot positions of the seat part 1 can be seen very clearly, that during the entire pivoting process, the distance between the seat part 1 and the backrest part 2 not changed.

Another possible position of the chair is shown in Fig. 3, in which the bed box 4 only is partially pulled out of the bed frame 11 and the backrest part 2 is opposite to that in FIG. 1 seat position shown is at an incline.

The seating furniture is also shown in a sitting position in FIG. 4, the direction of the backrest part 2 facing tab 6 is rotatably fixed at one end to the bed box 4, while on the the other end of a pivot lever 9 of the adjustment fitting 5 is connected.

At the end of the tab 6 assigned to the bed box 4, a ring segment-shaped elongated hole 7 is provided, in which a stop pin 8 fixed to the bed box 4 is guided and through their interaction the pivoting movement of the tab 6 is limited.

In order to stabilize the movement of the tab 6, a tension spring 10 is provided which, on the one hand, is attached to the Tab 6 and on the other hand to the stop bolt 8 is attached.

5 shows the seat part 1 and the backrest part 2 in a horizontal position, the tab 6 pointing in the direction of the seat part 1. Here, too, you can see how the pivoting range of the bracket 6 is limited by the elongated hole 7 in the form of a segment of a ring and the stop bolt 8 is.
