Upholstered furniture

The innovation concerns an upholstered furniture with a backrest frame and a seat section frame.

Upholstered furniture, particularly sofas, generally have a fixed seat section frame on which one or more seat cushions are arranged, and a fixed backrest frame against which one or more back cushions are supported, which are arranged at a certain angle to the vertical. However, a given angle of the back cushion is not perceived as comfortable by every sofa user. Also, depending on the activity or resting position, one and the same user may need to sit more upright at one time and more reclined at another. For this purpose, free cushions can be arranged between the user's back and the back cushion, but at best these only partially form a satisfactory support for the sofa user's back and are also an unstable support. Also, only a different angle of the support for the user's back can be achieved with a single cushion.

One aim of the innovation is therefore to present an upholstered piece of furniture with a backrest frame and at least one back cushion, which can be guided and locked into different inclined positions.

The upholstered furniture according to the invention is characterized in that the backrest frame has at least one upright, stationary column part and at least one pivoting frame which is connected to the stationary column part in an articulated manner and can pivot about a horizontal axis and be locked in different positions.

which is connected to a back cushion.

Advantageous embodiments of the innovation emerge from the dependent claims.

The subject of the innovation is explained in more detail below using the drawings. It shows

Figure 1 shows a partial section through a sofa in which the swivel frame and the back cushion supported by it are in a first position,

Figure 2 is a section similar to that of Figure 1 through a fully drawn sofa in which the pivoting frame and the back cushion supported by it are in a second position, and Figure 3 is a diagrammatic view of a sofa with two seats, the two back cushions being in different positions.

The sofa shown in the figures has a backrest frame 1, which is made of e.g. metal or wood. This backrest frame 1 is connected to a seat section frame 2, which is also made of e.g. metal or wood. The backrest frame 1 and the seat section frame 2 have footrests, of which the footrests 20, 21, 22 are shown in the figures.

Seat cushions 17, 17A, 17B are located on the seat section frame 2. The embodiment shown contains only two seats, i.e. two seat cushions 17A, 17B, but the number of seats and thus the number of seat cushions can also be higher.

Furthermore, the sofa of the shown version has an armrest 23, 24 on both sides.

In the backrest frame 1, pivot frames 4 are hinged to their associated column parts 3, which basically form part of the backrest frame 1. Each pivot frame 4 has a

Guide rail 14. Guide members 15, 16 are guided longitudinally in the guide rails 14, which guide members 15, 16 are firmly connected to a respective back cushion 5 (Fig. 1, 2) or 5A; 5B (Fig. 3). This means that the back cushions 5, 5A, 5B can be moved along the respective guide rails 14 assigned to them in a direction towards the respective seat cushion 17 and away from it.

At its upper end region, the pivot frame 4 is hinged to a respective column part 3 by means of a hinge 6, wherein the pivot axis 7 of the hinge 6, called the first pivot axis, runs between the respective back cushion 17 and the stationary column part 3.

As a rule, there are two column parts 3 arranged next to each other per seat, which are connected to a back cushion 5, 5A, 5B via pivoting frames and corresponding guide members 15, 16.

Below the hinge 6 and at a certain distance from it there is a pivoting device 8 which forms a further connection between the column part 3, i.e. the fixed backrest frame 1, and the pivoting frame 4.

This pivoting device 8 has a triangular plate 25 in the embodiment shown. An arm 11 is hinged to this plate 25, i.e. there is a first pivot joint 10 which determines a second pivot axis 9 in relation to the suspension of the pivot frame 4 on the column part 3.

It should be noted that the first

Pivoting axis 7 runs between the respective back cushions 5, 5A, 5B and the respective column conductor 3, but the said second pivoting axis 9 runs on a side of the respective column parts 3 facing away from the back cushions 5, 5A, 5B.

The length of the arm 11 is variable, i.e. it has two parts that can be moved longitudinally relative to each other.

At the opposite end, the arm 11 is hinged to the pivot frame 4 via a second pivot joint 12, which determines a lower pivot axis 13.

Furthermore, the two-part arm 11 has a locking fitting 18 of known design, so that the arm 11 can be locked in a respective longitudinal position.

Figure 1 now shows the back cushion with its pivoting frame 4 in its basic position and runs in the known manner slightly inclined to the vertical.

In order to achieve a slightly flatter position, e.g.

of Figure 2, the user pivots the back cushion 5 about the first pivot axis 7 of the hinge 6 by pulling the lower area of the back cushion 5 forwards. This pivoting movement can be carried out step by step in that a predetermined number of different inclinations are determined by the respective locking fitting 18, i.e. the back cushion 5 can be locked in a predetermined inclination due to the locking fitting 18 of the arms 11. Consequently, the back cushion 5 forms a stable support or rest for the back of a user of the sofa in every inclination.

Since the lower, wider edge of the back cushion 5 (the bottom left edge in Figures 1 and 2) would move away from the top of a respective seat cushion 17, 17A, 17B in a pure pivoting movement, the back cushion 5 can slide downwards along the guide rail(s) 14 due to the guide members 15, 16 so that it rests securely on the top of the seat cushion 17, 17A, 17B again, as shown in Figure 2.

Figure 3 shows the two possible positions of the back cushion, with position 5A corresponding to that of Figure 1 and position 5B corresponding to that of Figure 2. It should be noted that, as in the above description of the two-part arm 11 with the locking fitting 18, intermediate positions are also possible.

In each backrest frame 1 there is also an extendable or retractable headrest bracket 19. This headrest bracket 19 is guided in the respective column part 3 and held in a respective position, e.g. by frictional engagement in the column part 3.

This headrest bracket 19 is shown in the extended state in Figures 1 and 2. In this extended state, a cushion 26 slit in the middle can be put over the bracket 19 so that a padded headrest is provided for the user.

When not in use, the cushions 26 can be arranged next to the armrests 23, 24 and leaned against them.

Figure 3 shows the headboard bracket 19 associated with the back cushion 5B, drawn with solid lines in the extended state. The recessed state of the respective headboard bracket is shown with dashed lines for both back cushions.
