Description

2 AT 009 734 U1

The invention relates to a convertible into a bed seating, whose backrest is pivotally supported by means pivotally mounted on her arms in the plane of the seat surface of a seat cushion, wherein an additional cushion is provided which forms a lying surface in connection with the seat cushion and the backrest.

In a known furniture of this type, the seat cushion is supported on its front side via rollers on the ground and the additional cushion is arranged standing upright in the sitting position of the furniture at its rear side.

By the invention, a piece of furniture is to be created in which no rolling on the floor and this possibly damaging rollers are present and in which, moreover, no space at the rear of the furniture for the upright additional cushion is required.

The object underlying the invention is achieved in that the seat cushion is mounted by means of parallelogram in the furniture frame and the additional cushion is movable from the reclining position in a seat cushion located in the sitting position.

Suitably, the arms of the backrest are pivotally mounted on an extension of a parallelogram.

In order to allow the movement of the additional cushion in its raised position, in one embodiment of the invention, the parallelogram are guided in rails in the furniture frame and provided with arms at the ends of the additional cushion is articulated.

In another possible embodiment of the invention, the additional cushion is guided in rails which are pivotally connected via arms with the parallelogram of the seat cushion.

To guide the additional cushion at least one pivot arm is provided in both cases, which is hinged at one end to the additional cushion, the other end on the furniture frame.

In a preferred embodiment of the invention, a self loading scooter receiving a bed cover is arranged at the rear end of the additional cushion.

On convertible seats arranged self-scooter, which receive a duvet cover, are known per se. However, the known self-propelled rollers or the bed covers rolled up thereon can only cover two cushions at a time. If a third pad is provided, it will not be covered by the unrolled bed cover. In an arrangement according to the invention, however, all three cushions, namely the seat cushion, the back cushion and the additional cushion, can be covered by the covering unrolled by the self-propelled roller.

It is particularly useful in the context of the invention, when the self-scooter is mounted easily removable from above. Thus, the rolled up on the self-roll bed cover can be easily replaced. This is particularly advantageous in tourist accommodation and the like.

The invention will be described in more detail below with reference to exemplary embodiments illustrated in the drawings, without being limited to these examples. Showing:

Fig. 1 in side view partially cut a piece of furniture according to the invention in a lying position;

Fig. 2 shows the furniture of Figure 1 in an intermediate position when reconverting in the sitting position.

Fig. 3 shows another position of the furniture in the reversion to the sitting position;

4 shows an intermediate position of the convertible seat;

5 shows the furniture according to the invention in the sitting position. 3 AT 009 734 U1

Fig. 6 shows a modified embodiment of the invention in a reclining position, wherein the bed cover is not covered.

According to the drawings has a furniture according to the invention, a furniture frame 1, a seat cushion 2, a back cushion 3 and an additional cushion. 4

At the seat cushion 2 and its seat cushion frame 5 Parallelogrammlenker 6, 6 'are pivotally mounted on a fastening part, the pivotable bearing opposite ends are hinged in a slide strip 7. The slide bar 7 is longitudinally displaceable in a mounted in the furniture frame 1 rail 8.

At the additional cushion 4, an angle 9 is fixed to the connected to the parallelogram 6 and 6 'connected arms 10 are hinged. At the same angle 9, a pivot arm 11 is also articulated, the other end is pivotally mounted in the furniture frame 1.

In the preceding description, the single number was used for the individual parts. It should be emphasized, however, that these parts are present on both sides, thus in each case twice.

On the back pad 3 arms 12 are articulated on both sides, the other end are pivotally mounted on an extension 13 of the parallelogram 6.

The seat cushion 2 is equipped with an automatically extendable foot 14, the back pad 3 with a manually pivotable foot 15. The embodiment of the automatic transmission of the foot 14 which is not relevant to the present invention is described in AT 009 014 and is therefore not repeated here.

At the rear end of the additional pad 4 a self-propelled roller 16 is arranged, which receives a bed cover 18 whose free end is fixed at 17 on the back pad 3.

In the lying position of the furniture covers the bed skin 18 therefore all three pads 2, 3 and 4, so that the underlying furniture fabric of all three pads is protected.

In order to easily replace or clean the clothing 18, the self-scooter 16 is mounted easily removable from above. This can e.g. in that the two axes of the self-roller are mounted in upwardly open slots, e.g. can be closed by a rotary closure.

In order to bring a furniture according to the invention from the lying position shown in Fig. 1 in the sitting position of FIG. 5, the back cushion 3 is raised for the time being, wherein he performs by means of its arms 12 a kind of rolling motion. He gets into the position of FIG. 2.

After folding the feet 15, the back pad 3 is further rolled until it reaches the position of FIG. According to the articulation of the arms 12 on the extended arm 13 of the back pad 3 is in this position before the end of the seat cushion 2 on this. This is advantageous because it allows the operator to access the back pad 3 from the front.

Now, the seat cushion 2 is raised with the back pad 3 lying thereon, wherein it is pivoted by means of the parallelogram 6 and 6 '. At the same time the additional cushion 4 is moved according to the arms 10 down. The parallelogram link 6 and 6 'slide in the rail 8, wherein the pivot arm 11 performs the additional cushion 4. When the additional cushion 4 moves upwards into the lying position, this guide is important because it creates the smallest possible gap between the additional cushion 4 or the self-propelled roller 16 and the rear furniture wall.

4 AT 009 734 U1 Finally, the sitting position according to FIG. 5 is achieved. During the entire movement, the bed cover 18 is rolled up by the spring force of the self-roller 16. For reasons of clarity, the bed cover 18 is not shown in FIGS. 3, 4 and 5. In the embodiment according to FIG. 6, the parallelogram links 6 and 6 'are mounted directly in the furniture frame 1. The again connected to the parallelogram 6 and 6 'arms 10 are pivotally connected at 19 with a rail 20. The additional cushion 4 is slidably mounted in the rail 20 via an angle 21. Claims: 1.
