Abstract

In a fitting for pivoting the upper part (4) of a split backrest of seats, which are preferably convertible into reclining furniture, two downwardly projecting arms (5, 6) are pivotally mounted at the upper part (4), at the lower ends depending one Handlebar (7, 8) is articulated. Each of these links (7, 8) is pivotally mounted in the furniture frame (1) above the plane (10) of the seat cushion (2). As a result, a space-saving pivoting of the upper part (4) is achieved.

The invention relates to a fitting for pivoting the upper part of a split backrest of seating, which are preferably convertible into reclining furniture.

Lately, seating with a low height of the backrest has become fashionable. However, in order to not have to do without the comfort of a high backrest, namely support of the shoulder area and also of the head area, one can divide the backrest and swivel the upper part by means of a fitting and swivel it up again if necessary, but the use of hinges is not possible; when placed on the front, so the padded side, a hinge would interfere and when placed on the back of a large gap would arise when folding the upper part, so yes both parts of the backrest should be covered by a single piece of upholstery fabric. The invention has set itself the goal of creating a fitting of the type mentioned, which allows the pivoting of the upper part of the split backrest in a nearly perfect manner.

This is achieved by the fact that two downwardly projecting arms 20 are pivotally mounted at the upper part, at the lower ends depending a handlebar is hinged, each of these arms is pivotally mounted in the furniture frame above the plane of the seat cushion.

In experimental models, it has been found that the gap between this part and the lower part, which arises when the upper part of the backrest is pivoted, is very small, so that the furniture fabric spanning the two parts is only slightly stretched. Moreover, the seat cushion can be moved in the sitting position of the furniture to the rear, because the fitting according to the invention does not cover the area above the plane of the seat cushion.

In a preferred embodiment of the invention, the arm closer to the lower part of the backrest is pivotally connected to the arm of the other arm, and furthermore this arm is connected to a projecting lug on which a gas spring acts.

Further, a stop is arranged, which cooperates with one of the links. Advantageously, the arms and handlebars are arranged on each side of the furniture and the two links of the other two arms connected by means of a cross member, is arranged at the approximately center of the approach. It is therefore only a gas spring for the operation of the fitting required. The invention will now be described in more detail with reference to an embodiment shown in the drawings, without being limited to this example.

1 shows a furniture equipped with a fitting according to the invention in a diagrammatic view obliquely from above, wherein the side facing the viewer is broken off in the region of the fitting;

Fig. 2 shows the fitting from the side in view at a position in which the upper part of the backrest is folded down; Fig. 3 shows an intermediate position and

Fig. 4, the folded-up position of the upper part of the backrest.

According to the drawings, a seat cushion 2 and a backrest is mounted in a furniture frame 1, which consists of two parts 3 and 4. At the upper part 4 of the backrest two 55 arms 5 and 6 are pivotally mounted, which protrude from the upper part 4 down. On the arm 5 attacks

Claims (4)

3 AT 008 579 U1 a handlebar 7 and the arm 6, a handlebar 8 at. The two links 7 and 8 are pivotally mounted in the furniture frame 1 via a mounting plate 9. The bearing of the two links 7 and 8 takes place above the plane of the seat cushion 2. The handlebar 7 is connected to a projecting lug 11 on which a gas spring 12 engages. 5 The arms 5, 6 and handlebars 7, 8 are arranged in the embodiment on each side of the furniture and the two links 7 are connected by means of a crossbar 11 ', at the approximately center of the projection 11 is arranged. The connection of the neck 11 with the arms 7 is therefore via the traverse 11 'and it is only a gas spring 12 is required. In the folded-down position of FIG. 2, the force line 13 of the gas spring 12 extends below the pivot point 14 of the arm 7. As a result, the upper part 4 of the backrest is pressed down. If this upper part 4 is raised, it is rotated about a theoretical pivot point 15 until the rotational movement is stopped by a stop 16 interacting with the link 7. In this position, the gas spring 12 is still under tension, so that the upper part 4 of the backrest is securely held in the raised position. In order to pivot the upper part 4 of the backrest down, it only needs to be pressed on it until the position of FIG. 2 is reached again. As can be seen from FIG. 3, the gap S produced during the conversion of the furniture between the two parts 3 and 4 is relatively small. The over the two parts 3 and 4 extending upholstery fabric (not shown) is therefore only very slightly stretched, so that no fold is formed. Also, the dimension A (Figure 2) and the dimension B (Figure 4) are approximately equal. 25 In both positions of the upper part 4 of the backrest, therefore, the total length of the upper part 4 and lower part 3 on the padded side is approximately equal. A wrinkling of the furniture fabric is also avoided. Because the fitting is arranged above the plane of the seat cushion 2, the seat cushion 2 can be moved backwards. In other words, this means that the seat cushion 2 can be pulled out of the sitting position out, so that a possible lying surface is increased. A further enlargement of the lying surface can of course be achieved in a known manner by additional pads. 35 Claims: 1. fitting for pivoting the upper part (4) of a split backrest of seating furniture, which are preferably convertible into reclining furniture, characterized in that 40 at the upper part (4) has two downwardly projecting arms (5, 6) pivotally mounted are, at the lower ends of each a link (7, 8) is articulated, wherein each of these links (7, 8) in the furniture frame (1) above the plane (10) of the seat cushion (2) is pivotally mounted. 2.
