Abstract

A convertible into a bed seating furniture has a seat cushion (2) and at least one additional cushion (3), wherein the additional cushion (3) in the sitting position of the furniture under the seat cushion (2) and in a raised position subsequent to the pivoted seat cushion (2 ) lies. Further, for pivoting the seat cushion (2) and for lifting the additional cushion (3) Parallelogrammlenker (4, 5) and springs (12, 13) are arranged. The Parallelogrammlenker (4, 5) are hinged at one end to the seat cushion (2), at the other end on the furniture frame (1) and at the furniture frame (1) hinged end, they are extended at an angle. The angle (7, 8) via tabs (9, 10) on the additional cushion (3), and at least between an angle (7, 8) and the additional cushion (3), a spring (12, 13) is arranged. As a result, possible damage to the pad by the spring (s) is reliably avoided.

Description

• * > ········································································································································································································

The invention relates to a convertible into a bed chair with a seat cushion and at least one additional cushion, wherein the additional cushion in the sitting position of the furniture under the seat cushion and in a raised position then to the pivoted seat cushion, and further for pivoting the seat cushion and the Lifting the additional pad parallelogram link and springs are arranged.

In known furniture of this type, the springs are arranged laterally, which has the disadvantage that during lifting the springs are moved past the upholstery and can damage them.

The invention has set itself the goal of creating a piece of furniture of the type mentioned, in which the springs are arranged entirely below the cushion.

It should be noted in this context that the term "pad" in the present description, both the actual upholstery and the frame or the frame on which the actual upholstery is understood.

The object underlying the invention is achieved in that the parallelogram are hinged at one end to the seat cushion, at the other end to the furniture frame and are extended at the hinged end at the furniture frame angular, which angle attack on tabs on the additional cushion, and at least between an angle and the additional cushion a spring is arranged.

To guide the additional cushion when lifting it attacks according to a further feature of the invention on the additional cushion mounted on the furniture frame pivot arm.

The invention will be described in more detail below with reference to an embodiment shown in the drawings, without being limited to this example. Showing:

Figure 1 shows an inventive furniture partially in section in the sitting position.

Figure 2 shows an intermediate position in the conversion of the furniture in the lying position.

Fig. 3 is a bottom view in the intermediate position of Figure 2, wherein only one half of the furniture is shown. Fig. 4, the furniture according to the invention in a lying position.

According to the drawings, a seat cushion 2 and an additional cushion 3 is pivotally mounted in a furniture frame 1.

At the seat cushion 2 and its frame engage two parallelogram 4 and 5, the lower ends are mounted on a rail 6 on the furniture frame 1. The lower ends of the parallelogram 4 and 5 are extended by elbows 7 and 8.

At the elbows 7 and 8 tabs 9 and 10 are articulated, which engage the additional cushion 3.

On furniture frame 1, a pivot arm 11 is mounted, which also acts on the additional cushion 3.

Between the seat cushion 2 and the elbows 7 and 8, springs 12 and 13 engage.

The seat cushion 2 is equipped with an automatically extendable foot 14. The embodiment of the automatic transmission of the foot 14, which is unimportant for the present invention, is described in AT 009014 U1 and is therefore not repeated.

In the conversion of the furniture from the sitting position shown in Fig. 1 in the lying position of FIG. 4, the

Seat cushion 2 is raised and thereby enters the intermediate position according to FIGS. 2 and 3.

In this movement of the seat cushion 2, the additional cushion 3 on the Parallelogrammlenker 4, 5, the elbows 7,8 and the tabs 9, 10 are also raised. The additional cushion 3 is guided by the Schwenkarni 11 and the lifting is supported by the springs 12, 13.

When lowering the seat cushion 2, the additional cushion 3 is further raised until the two pads 2 and 3 lie in a plane and the reclining position is reached in FIG. 4.

The reconversion of the furniture is done in the opposite way.

Numerous modifications are possible within the scope of the invention. So could be used with lighter pads and only a spring 12 or 13. The furniture can also be supplemented by a foot pad, which can be e.g. in the sitting position of the furniture serves as a backrest.
