Description

Seat Lieαemöbel

The invention relates to a seat reclining furniture.

Seat reclining furniture are known from the prior art and are sometimes referred to as cross sleepers. Consisting of a mounted on a foot construction two- or three-part seat-lying surface of joints with interconnected parts as a basis and an overlying, partly also continuous upholstery, this furniture allow by preferring the seat and / or flaps of the backrest forming a lying surface. In such a seat reclining furniture armrests is omitted in most cases, or they are fixed to the foot construction, so do not form part of the bed in the lying position and lose their function there. A known alternative is the unfolding of the armrests in the sitting position, wherein the armrests are designed as part of the seat-lying surface. In order to achieve a sufficiently large lying surface for two people, such reclining seat furniture with a seat-lying surface, consisting of seat and backrest, but compared to a sofa on an unusually high backrest and a large seat depth, which has an unsatisfactory ergonomics result , In a three-part seat-lying surface, however, by design results in the sitting position a double and thus large-volume seat or backrest, which is not desirable from an optical point of view.

The object of the invention is to provide a seat reclining furniture with a seat-lying surface, wherein the seat-lying surface in a sitting position an ergonomically optimized sofa with armrests and in the lying position forms a continuous, comfortable for two people lying surface without protruding elements, and wherein the seat reclining furniture is designed so that it can be easily moved from the sitting position to the reclining position, and vice versa.

The object is achieved by a seat reclining furniture having a flat surface, a backrest, a backrest part and a front four flat, planar furniture elements, each furniture element is pivotally mounted on two other furniture elements, so that total at least four pivot axes are present, and wherein the flat, planar furniture elements can be pivoted to each other so that the furniture elements and the pivot axes extend in a lying position of the seat reclining furniture in a plane. As a backrest part is in contrast to the backrest that furniture element referred to, which serves as an armrest and / or storage. Since the four essential furniture elements seat part, backrest, backrest and front part are flat and flat and extend in the reclining position of the seat reclining furniture in a plane, the reclining furniture offers in its lying position with the maximum of four furniture elements lying surface. In this context, the feature that the flat, planar furniture elements extend in a plane, that there are no furniture element sections or other components of the seat reclining, which protrude toward this later support surface for a user of the seat reclining furniture out of this level , Due to the furniture structure with at least four mutually pivotable and cleverly coupled furniture elements, the large bed can be transformed with simple means so that an ergonomically optimized sofa with "normal" seat depth and backrest is created.

Particularly preferably, the at least four pivot axes are parallel to each other and spaced from each other. This results in the advantage that in the sitting position in the region of the seat a trifold folded form and in the region of the side armrests of the backrest part a simply folded shape is formed. About the distance of the pivot axes, the seat reclining furniture can be ergonomically optimized.

In detail, for example, the front part and the seat part are pivotally connected to each other and define a first pivot axis.

The front part and the backrest part may also be pivotally connected to each other and define a second pivot axis.

Preferably, the seat part and the backrest are pivotally connected to each other and define a third pivot axis.

Finally, the backrest and the backrest part can be pivotally connected to each other and define a fourth pivot axis. In one embodiment, the front part and the backrest part are each U-shaped, wherein the front part and the backrest part in the lying position of the reclining seat surround the backrest and the seat part.

With this construction, the reclining seat furniture is particularly stable and resilient in its reclining position.

In particular, the two free leg ends of the U-shaped front part are connected to the two free leg ends of the U-shaped backrest part, wherein the enclosed area is filled in the lying position of the seat reclining furniture by the rectangular shaped seat part and the rectangular formed backrest. As a result of this shaping of the planar furniture elements, the seat / reclining furniture has an ergonomically advantageous contour in the sitting position as well as a stable, continuous and flat lying surface in the lying position.

Preferably, a foot construction is provided, wherein the four furniture elements are pivotally attached to the foot construction and define a fifth pivot axis. Although the furniture elements are merely pivoted relative to the foot construction, the foot construction ensures both in the sitting position and in the lying position a safe and reliable state of the seat reclining furniture.

The previously defined third and fifth pivot axis are in one

Embodiment of the seat reclining furniture substantially identical. The "folding" or "unfolding" of the seat reclining furniture, i. the pivoting of the furniture elements and the foot construction relative to each other in the sitting or lying position is greatly facilitated as a result of this merger of the pivot axes for the furniture user.

In one embodiment, a support member is fixed to the front part and the backrest part in each case so that the reclining seat furniture is supported in its lying position on the support elements on a footprint of the seat reclining furniture. In particular, in the lying position in which the furniture elements span a large flat surface, a risk of tipping the seat reclining furniture is significantly reduced by the support elements. In the lying position, they ensure, together with the foot construction, a secure position of the seat reclining furniture. In this embodiment, a locking means for releasably locking the foot construction may be provided with the support member attached to the front part in order to lock the seat reclining furniture in a sitting position. With this locking an unintentional pivoting of the seat reclining furniture from the sitting position in the reclining position or in an intermediate position is reliably prevented.

The seat part and the backrest part define a seat surface and a seat part, respectively

Backrest surface, wherein the seat surface and the backrest surface in a sitting position of the

Seat recliners are preferably not parallel. This arrangement of the furniture elements contributes in the sitting position to an ergonomically advantageous shape of the

Seat reclining furniture at.

Further, a spring may be provided which connects two furniture elements, wherein the spring supports a pivoting of the furniture elements from the lying position in a sitting position. In particular, when pivoting the furniture elements from the lying position to the sitting position, the user of the seat reclining furniture must apply a certain amount of force, whereas pivoting from the sitting position to the reclining position after releasing a possibly existing lock substantially abruptly and without effort of the user expires , The spring now provides a compensation that both aforementioned pivoting movements with little and about the same effort are feasible. Preferably, the spring is a tension spring which connects the front part with the seat part.

In order to dampen the effect of the spring, an attenuator may be provided, which particularly preferably connects the seat part with a foot construction of the seat reclining furniture and increases the ease of use of the seat reclining furniture.

In a further embodiment, the seat reclining furniture is associated with a one-piece padding with slots. With the one-piece padding the ease of use is further increased, since a positioning of individual upholstery elements after pivoting the seat reclining furniture is eliminated. The slots allow the pivoting of the seat reclining furniture adaptation of the pad to the changed positions of the individual furniture elements. The padding is preferably on the flat furniture elements and is releasably fixed. If all fixing points of the upholstery lie on a straight line which is parallel to one of the swivel axes, the furniture elements can be pivoted particularly well, since a displacement of the upholstery relative to the furniture elements is easily possible.

In the area along the pivot axes, the padding grooves or incisions may have to adapt well to the shape of the seat-recliner and not to hinder pivoting of the furniture elements.

The four flat, planar furniture elements are each designed as a frame with applied grid in a preferred embodiment. They are therefore simple and inexpensive to produce, but at the same time have the necessary stability and resilience to the stresses occurring.

In the seat reclining furniture according to the invention, in contrast to the prior art, the lying surface is formed of four hingedly interconnected furniture elements, so that there is a trifold folded form in the seating position in the region of the seat and a simply folded shape in the armrest , This creates, in addition to the seat and backrest, a U-shaped element that forms the armrests and a shelf, as well as another U-shaped element, which forms the front part. This structure allows in the sitting position a compact, ergonomically advantageous shape, the armrests are not parallel to the seat. In the lying position, a continuous, uniform lying surface without protruding parts is created from the four furniture elements mentioned above. When using a one-piece upholstery, make sure that corresponding grooves along the kinks make it possible to fold into the sitting position. Likewise, the difference in length of the padding resulting from differential expansion in the trifold folded region of the seat and in the simply folded region of the armrests must be compensated by grooves in the padding.

A one-piece upholstery should be stored floating on the four-part base construction of the seat-lying surface and be fixed only in the area of the connection of the seat and backrest. Thus, as Padding a continuous, provided with two slots element, such as a mattress, or even a multi-part element are used.

For the seat-lying surface comes as a base, which carries the padding, a multi-part construction used. This is provided as hinged frame members in conjunction with a type of slatted frame or the like (e.g., wire mesh), but may be constructed of sheet material.

In order to enable a simplified storage and locking of the seat-lying surface, this is to be connected articulated in the area between the seat and the backrest to a foot construction. The U-shaped parts of the seat-lying surface can be provided with obliquely mounted support brackets that support the sitting-lying surface in the lying position and at the same time function as a lock in the sitting position by a support bracket is hung in the foot construction. The oblique arrangement of the support bracket entails that the folding is facilitated in the sitting position by the force required for this is reduced. In addition to the folding in the sitting position with spring elements or the like, between two furniture elements, e.g. the seat part and the front part are tense, be relieved.

Further features and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings. In these show:

1 shows a seat reclining furniture 20 having a seat surface part 4, a backrest 5, a front part 6 and a backrest part 7 four flat, planar furniture elements, each furniture element 4, 5, 6, 7 pivotally attached to two other furniture elements is, resulting in four pivot axes A, B, C, D. In contrast to the backrest 5, the furniture element referred to as a backrest part 7 is a combination of side armrests 22 and a shelf 24 of the seat reclining furniture 20. Furthermore, the seat reclining furniture 20 comprises a foot construction 1, which ensures a secure state of the seat reclining furniture 20 , The four furniture elements 4, 5, 6, 7 are pivotally attached to the foot structure 1 and define a fifth pivot axis E, which is substantially identical to the third pivot axis C.

In addition, two support elements 2, 3 can be seen in FIG. 1, over which the seat reclining furniture 20 is supported in its reclining position (cf., FIGS. 2 and 3) on a footprint. The one support element 2 is fastened to the front part 6 and the other support element 3 on the backrest part 7.

The four pivot axes A, B, C, D are parallel to each other and each spaced from each other. The front part 6 and the seat part 4 are pivotally connected to each other and define a first pivot axis A. A second pivot axis B is through the front part 6 and the

Backrest part 7 defined, which are also pivotally connected to each other. The

Seating part 4 and the backrest 5 are pivotally connected to each other and define a third pivot axis C and finally the backrest

5 and the backrest part 7 also pivotally connected to each other and define a fourth pivot axis D.

In FIG. 1, the seat reclining furniture 20 is in a first end position, the so-called sitting position. In contrast, Figure 2 shows the seat-reclining furniture 20 after the pivoting of the furniture elements 4, 5, 6, 7 in a second end position, the so-called reclining position. From Figures 1 and 2 it is clear that the flat, planar furniture elements 4, 5, 6 7 can be pivoted to each other so that they are in the lying position of the seat Liebenöbel 20 together with the pivot axes A, B, C, D extend in a plane. The front part 6 and the backrest part 7 are each U-shaped, wherein the front part 6 and the backrest part 7 in the reclining position of the seat reclining furniture 20, the backrest 5 and the seat part 4 enclose. In detail, the two free leg ends of the U-shaped front part 6 are connected to the two free leg ends of the U-shaped backrest part 7, which correspond to the side armrests 22, wherein the enclosed area in the lying position of the seat reclining furniture 20 by the rectangular shaped seat part 4 and the rectangular trained backrest 5 is filled. In an alternative embodiment, it is also conceivable that the seat part 4 and the backrest 5 are not rectangular and the free leg ends of the U-shaped front part 6 and the U-shaped backrest part 7 do not extend parallel to each other. However, it is crucial that the flat furniture elements 4, 5, 6, 7 form a substantially continuous, flat surface in the lying position.

The seat reclining furniture 20 includes a seat-lying surface, which is formed by the pivotally connected furniture elements 4, 5, 6, 7. In the illustrated embodiment, the seat-lying surface is associated with a one-piece padding 10, which has at the intended kinks grooves 11 and a recess 12 (Figure 3). The grooves 11 can be replaced by a plurality of smaller grooves with a total of the same cross-section, whereby the padding 10 in the lying position of Figure 3, the body weight of a user of the seat reclining furniture 20 can support more evenly.

In order to allow the folding in the sitting position, the one-piece padding 10 must have two slots 13, as shown in Figure 2. Instead of the one-piece padding 10 and a multi-part padding corresponding to the furniture elements 4, 5, 6, 7 are used. The furniture elements 4, 5, 6, 7 are executed in the illustrated, exemplary construction of Figure 1 and 2 as a tubular frame with wire mesh applied thereto. The furniture elements 4, 5, 6, 7, in conjunction with the padding 10 shown only schematically, the seat-lying element. This is pivotally connected to the connection between the seat part 4 and the backrest 5 with the foot construction 1. Thus, in the reclining position (Figures 2 and 3) creates a stable bed surface, the front part 6 and the backrest part 7 are arranged obliquely Support elements 2, 3 supported down against a footprint for the seat reclining furniture 20. In the example shown, these supports are designed as a bracket, but other shapes are possible.

To bring the illustrated reclining furniture 20 from the lying to the sitting position, the front part 6 and the backrest part 7 is raised in the region of the connection of the two furniture elements, so that the seat reclining furniture 20 moves to a first intermediate position according to FIG , This results in the area of the armrests 22 a simple kinked shape and in the area of the seat surface part 4 a triple kinked shape. With further lifting, as shown in Figure 5, the front part 6 and thus the support member 2 works inwardly towards the foot construction 1, so that the seat reclining furniture 20 occupies a second intermediate position. This movement is facilitated by a spring 9, which is provided between the seat surface part 4 and the front part 6 and formed as a tension spring. The support element 2 is lifted over a rod part 14 of the foot construction 1. Upon subsequent lowering, the support element 2 slides guided by the rod portion 14 of the foot structure 1 in its end position and locks the seat reclining furniture 20 in its sitting position shown in Figure 6. In the example shown, the front part 6 and the backrest part 7 form an angle of 90 °, but also variants with another angle are conceivable. As shown in Figure 6, in the sitting position, the seat surface of the seat surface part 4 need not be arranged parallel to the backrest surface of the backrest part 7, but can be designed ergonomically advantageous by appropriate design of the dimensions. The support element 2 of the front part 6 has a locking means 8, which secures the seat reclining furniture 20 against unintentional pivoting from the sitting position to an intermediate position or the lying position.

FIG. 4 diagrammatically shows an optional attenuator 26 with dashed lines, which dampens the action of the spring 9 and connects the seat surface part 4 to the foot construction 1. By combining the spring 9 with the attenuator 26 of the force required to pivot the furniture elements 4, 5, 6, 7 is reduced from the lying in the sitting position and increases the ease of use. The pivotal connection between the individual furniture elements 4, 5,

6, 7 is made in the embodiment according to Figures 1 to 6 by hinges 28 (see Figure 1). The hinges 28 are made, for example, in the manner of simple furniture hinges, wherein the industries of the hinge have an internal thread and attached directly to the furniture elements 4, 5, 6, 7, preferably welded. A hinge pin accordingly has an external thread and can be screwed into the trade. Particularly preferably, the pin is designed as Allen screw, so that the pivotal connections are solvable and the seat reclining furniture 20 can be disassembled for transport into individual parts.
