Description

The present invention relates to a sitting / lying furniture, in particular sofa bed, with a sitting / lying surface and at least one adjustable backrest element. Furthermore, the invention relates to a fitting arrangement for adjusting a arranged on a sitting / lying furniture backrest element.

Seating / reclining furniture with adjustable backrest elements are basically known, for example. The DE 20 2005 015186 . DE 20 2005 014017 . US Pat. No. 3,069,699 and the DE 20 2005 018701 ,

It is the object of the invention to provide a sitting / reclining furniture of the type mentioned, which is adjustable in the simplest possible way and at the same time versatile, and to provide a fitting arrangement for adjusting a backrest element of a sitting / lying furniture.

The object is achieved by a sitting / lying furniture with the features of claim 1 and in particular by a sitting / lying furniture, in particular sofa bed, with a sitting / lying surface and at least one backrest element, which is adjustable between a sitting position and a reclining position, wherein the backrest element covers a partial section of the sitting / lying surface in the sitting position and releases the partial section in the lying position, and wherein the backrest element is mounted on a base frame both in the sitting position and in the lying position. The one or more backrest elements may be designed in particular as an armrest and / or as a backrest.

The seat / reclining furniture according to the invention is characterized in that the one or more backrest elements are mounted in both adjustment positions on the base frame and thus claim no separate storage space when adjusting in the reclining position. In addition, the sitting / lying furniture has a high level of user comfort, as by the storage of the backrest elements on the base frame unintentional shifting or falling of the backrest elements is largely excluded.

According to a preferred embodiment of the invention, a plurality of, in particular adjustable in different ways, backrest elements are provided which define a rectangular seat surface in the sitting position and in the lying position a rectangular lying surface, wherein the lying surface both a greater width and a greater length than the Seat has. As a result, the seat surface and the lying surface can be optimally adapted to the respective type of use. Thus, it is possible, for example, to take advantage of the maximum width of the sitting / lying area in the lying position and to reduce this in the sitting position to a perceived as comfortable seat depth measure.

Preferably, the backrest element is along a non-linear, preferably circular path parallel to the sitting / lying surface and while maintaining its orientation relative to the sitting / lying surface at least in the sitting position and in the lying position, preferably also during the adjustment, movable. The backrest element is thus effectively offset or displaced between the sitting position and the lying position, but the path described during the adjustment process is not linear, but rather describes a circular arc, for example. An inadvertent adjustment of the backrest element is thereby avoided. Such an adjustment can be provided in particular for an armrest.

According to a further advantageous embodiment, the backrest element is pivotable about a horizontal pivot axis, wherein preferably the pivot angle is 90 ° or 180 °. Here, the backrest element is released by simply folding the previously covered part of the sitting / lying area.

It is preferred if the lying surface is formed by the upper side of a support part, wherein the pivot axis coincides at least approximately with an edge of the support part delimiting the upper side of the support part. In particular, the pivot axis also coincides with an edge of the backrest part.

Preferably, the support member is mounted on a support surface of a base frame, wherein the support surface protrudes at least on one side under the support member and the backrest element is supported in the lying position on the projecting part of the support surface. This makes it possible to transfer a resting in the sitting position on the support member backrest element by pivoting or folding at an angle of 180 ° in the lying position, in which it then preferably flush-connected to the lying surface and is an additional part of the bed.

According to a further preferred embodiment of the invention, the backrest element, which is preferably designed as an armrest, is mounted on a base frame by means of a fitting arrangement according to the invention described below, in particular with a vertical distance from the sitting / lying surface.

The object of the invention is further achieved by a fitting arrangement with the features of claim 9 and in particular by a

Fitting arrangement for adjusting a arranged on a sitting / lying furniture backrest element, with a parallel link arrangement comprising a pair of lying in a common adjustment plane, preferably identically designed arms, the handlebar each with its one end a first pivot point for articulation of a base frame of the seat / Liegemöbels and define with its other end a second pivot point for articulation of the backrest element, extending through the pivot points parallel to each other and perpendicular to the Verstellbene, and wherein articulated in the hinged to the base frame and the backrest element, the articulation points form the corners of a parallelogram ,

The fitting arrangement according to the invention makes it possible to displace or displace a backrest element arranged on a sitting / lying furniture without the orientation of the backrest element changing with respect to the sitting / lying furniture.

Preferably, the links are coupled together by a preferably single or multiple angled and / or cranked synchronization rod. The synchronization rod ensures in particular that a play-related tilting or jamming of the handlebars is prevented.

According to an advantageous embodiment, the synchronization rod is shaped and hinged to the handlebars, that a pivoting of the arm around the first pivot points is blocked upon reaching at least one adjustment position by the synchronization rod. The synchronization rod thus not only serves to synchronize the handlebar movement, but also serves as a stop for the handlebar movement in order to define the end positions of the adjustment range.

Further advantageous embodiments of the invention are specified in the subclaims, the description and in the drawings.

Detailed views of a sitting / lying furniture according to the invention in different adjustment positions.

According to Fig. 1 to 4 a seat / reclining furniture according to the invention 10 comprises a rectangular base frame 12 with a base member 14 which is supported on support legs 16 on the bottom side. On the base member 14 designed as a pad member support member 20 is arranged, the top of which forms a sitting / lying surface 22.

On one longitudinal side of the base frame 12 there is provided a backrest 28 which is pivotable about a horizontal axis and which is fastened to the base frame 12 in a manner which will be explained in more detail below. Armrests 24, 26 are provided on each of the two transverse sides of the sitting / lying furniture 10, wherein the one armrest 24 likewise extends around a horizontal axis is pivotally mounted. The other armrest 26 is displaceable or displaceable on the base frame 12 in a horizontal plane.

The armrests 24, 26 and the backrest 28 have a flat-square shape, wherein the flat sides in the in Fig. 1 and 2 shown sitting position parallel to the sitting / lying surface 22 are arranged. While the armrest 26 and the backrest 28 are spaced by approximately 0.5 to 1.5 times their height from the sitting / lying surface 22, the armrest 24 rests directly on the sitting / lying surface 22.

In the following, the adjustment of the armrest 24 between the sitting position and the lying position will be explained first.

The relevant horizontal pivot axis coincides with a transverse side, the seat / lying surface 22 bounding edge 30 together. To adjust the in Fig. 1 and 2 shown sitting position in the in Fig. 3 shown lying position, the armrest is pivoted about the edge 30 by 180 °. In the lying position, the armrest 24 is supported on a support surface 18 provided on the upper side of the base element. Preferably, the height of the armrest 24 corresponds to the height of the support part 20, so that the armrest 24 in the lying position is flush with the sitting / lying surface 22 and additionally expands it. The armrest 24 may, for example, be connected to the support part 20 by means of a seam connection formed between a cover of the support part 20 and a cover of the armrest 24, or by a portion of the cover.

Regarding Fig. 1 to 5 Now, the arrangement and operation of the backrest 28 will be explained in more detail.

As it especially looks like Fig. 5 As can be seen, the backrest 28 is articulated to vertical supports 32, whose respective lower ends are secured by means of cantilevers 44 to the base member 14. Upper end portions of the supports 32 are angled backwards and received in two adjustment positions in a formed in the interior of the backrest 28 cavity 34. At the upper end of a respective support 32, a preferably self-locking joint 36 is provided, via which the backrest 28 is articulated to the support 32. On the backrest 28 stops 38 are arranged, of which one cooperates in an end position of the backrest 28 with the support 32 and the limit the pivoting range of the backrest 28 to about 90 °.

In the sitting position ( Fig. 2 ) is the backrest 28 in a horizontal position and a portion of the backrest 28 covers a corresponding portion of the sitting / lying surface 22. In the lying position ( Fig. 3 ), the backrest 28 is folded upwards in a vertical position and thus releases the previously covered portion of the sitting / lying surface 22 free. This position can also be used as an alternative seating position with increased backrest height and seat depth.

The backrest 28 may be integrally formed or, as indicated by a dashed line, divided into two or more sections, in which case each section is pivotable for itself.

Including the 6 and 7 now the adjustment of the armrest 26 is explained in detail.

Two vertical, bar-shaped supports 42a, 42b are fastened via support arms 44 to a transverse side of the base element 14. At the upper end of each support 42a, 42b is a link 48 about the longitudinal axis of the respective Carrier 42a, 42b pivotally hinged. The other end of each link 48 is pivoted about a respective bolt 46 fixed to the underside of the armrest 26 about the longitudinal axis of the pin 46, the longitudinal axes of the pins 46 being spaced parallel to the longitudinal axis of the beams 42a, 42b. The ends of the links 48 articulated to the beams 42a, 42b define first pivot points, while the ends of the links 48 hinged to the bolts 46 define second pivot points. These articulation points form the corners of a parallelogram, so that the movable in a horizontal plane armrest 26 always maintains its parallel orientation to the transverse side of the base frame 12 when moving between different adjustment positions.

The links 48 are angled approximately at an angle of 90 ° and connected to each other via a synchronization rod 50. The synchronization rod 50 is articulated via two joints 52 provided at its ends in the region of the angling of the links 48 in third articulation points on the links 48, the plane of movement of the synchronization rod 50 lying in a horizontal plane which is below the horizontal plane of movement of the links 48. The synchronization rod 50 ensures reliable and trouble-free operation when adjusting the armrest 26th

The synchronization rod 50 is angled or cranked in each case in the region of its ends connected to the links 48, the regions of the angling or of the offset respectively being effective as blocking regions 54 and 56, respectively, in order to limit the adjustment range of the armrest 26. In the present embodiment, the synchronization rod 50 is formed such that the blocking portion 54 cooperates with the front bracket 42a and defines the seating position while the other locking portion 56 cooperates with the rear bracket 42b and the lying position defined. By appropriate design of the angled portions of the synchronization rod 50, the angular range can thus be defined by which the links 48 can be pivoted about the carriers 42a, 42b.

As in Fig. 6 it can be seen, in the sitting position, the second articulation points defined by the bolts 46 are offset slightly towards the rear relative to the corresponding first articulation points defined by the carriers 42a, 42b. This causes a locking of the armrest 26 in the sitting position, as acting only in the longitudinal direction of the sitting / lying surface 22 on the armrest 26, outwardly directed force alone can not cause adjustment of the armrest 26 in the lying position. Rather, an additional, forward, so parallel to the transverse side of the sitting / lying furniture 10 directed force component is initially required to adjust the armrest 26.

In the course of the adjusting movement, the bolts 46 move on a circular arc extending around the supports 42a, 42b from the sitting position to the lying position, wherein the swept-over adjustment range is slightly more than 180 °. The design of the armrest 26 and the distances of the articulation points are chosen so that it is also ensured for the armrest 26 that this covers a portion of the sitting / lying surface 22 in the sitting position and completely releases it in the reclining position.

As in Fig. 7 can be seen, are the handlebars 48 and the synchronization rod 50 below the armrest 26. Alternatively, it is also possible to integrate these in a formed on the underside of the armrest 26 cavity, so that they are no longer visible at least in the side view.

The fitting arrangement described with respect to the horizontal adjustment of the armrest 26 can also be used in a 90 ° rotated orientation, so that the movement levels of the arm or armrest are vertical and the armrest can be adjusted between a lowered and a raised position. The adjustable backrest element can also be used as a backrest.
