Reclining furniture with swiveling backrest

The invention relates to a reclining furniture item with a pivotable backrest, comprising a frame fixed to the frame, a support part arranged on the frame and longitudinally displaceable relative to the frame, for example a slatted frame, wherein the backrest part is pivotably held on the support part so that it can be adjusted from a flat or slightly inclined position to a steep support position.

Such a piece of furniture is, for example, a bed frame with a frame that is fixed to the frame and a support part that is arranged in the frame and can be moved longitudinally relative to the frame, which has a slatted frame, preferably with not only an adjustable backrest, but also with

adjustable thigh and lower leg support section.

Such reclining furniture is known in the prior art. One problem is that normally when the backrest is raised, the lateral reference plane of the reclining furniture changes, so that when the backrest is arranged flat, the person using the reclining furniture finds themselves with their head in the area adjacent to a bedside table, a wall-mounted light or the like. If the backrest is swiveled up, the user's upper body is displaced towards the foot end, so that, for example, the light arranged on the wall behind the bed is no longer ergonomically arranged and a bedside table or the like arranged next to the bed, in particular next to the headboard, is no longer within the user's reach.

Based on this state of the art, the invention is based on the task of creating a structurally simple type of adjustment option, through which it is achieved that the lateral reference plane is also adjustable for the user when the backrest is in the upright position.

does not change or changes only slightly compared to the flat orientation of the backrest.

To solve this problem, it is proposed that a first lever is articulated on the frame, preferably on its head-side end area below the support part, the free end of which is directed towards the foot part being articulated on the backrest part at a distance from the head-side end thereof, preferably approximately in the middle of its longitudinal extension, that a second lever is attached to the backrest part at a distance from the head-side end thereof, preferably approximately in the middle of its longitudinal extension, the free end of which is directed towards the foot part being articulated on the support part, preferably near the end of the backrest part directed towards the foot part, below the backrest part, and that a linear actuator is attached to the frame, preferably near the head-side end, the plunger of which is adjustable in the longitudinal direction of the frame being articulated on the support part, if necessary via a tab, the tab preferably being articulated on the articulation area of the second lever on the support part, so that when the plunger moves from the basic position, in particular from a position extended towards the foot part, into a working position, especially towards the head end, an upright

Pivoting movement of the backrest and a superimposed displacement of the support part towards the head end.

This design ensures that when the backrest is in a flat position, the backrest is approximately flush within the frame. As the backrest is increasingly swiveled up, a displacement movement of the support part on which the backrest is held is forced, so that the support part moves towards the head end of the recliner at the same time as the backrest is swiveled up. The result of this is that, for example, when the recliner is arranged with its head part against a wall, the light or similar equipment attached to the wall remains within the user's reach and in the user's field of vision even when the backrest is swiveled up into the high position, since the entire support part is simultaneously moved towards the head end of the frame, so that the reference plane to the side of the recliner and behind the recliner remains practically unchanged for the user. A bedside table or similar located next to the head end of the recliner is therefore also

••-•&dgr; -

The backrest is in an upright position and is easily accessible to the user.

The realization of these superimposed
The swivel/sliding movement is achieved by the simplest means, namely just two levers and the corresponding actuator, whereby, depending on the load and arrangement, the arrangement of the levers and the actuator can be arranged in the middle of the transverse extension of the recliner or also off-center, in pairs on both

Side areas of the lounge furniture. *"·*·.

To ensure a constraint-free swivel/sliding movement."·»»

It is also planned that the

.... • ■ the end of the first lever hinged to the backrest and the end of the second lever attached to it are arranged so as to be movable along the backrest.

For this purpose, it is provided in particular that the end of the second lever attached to the backrest part is held displaceably in a longitudinal guide rail of the backrest part and that the end of the first lever hinged to the backrest part is attached to the end or near the end of the second lever on this

hinged and thus indirectly connected to the backrest.

In order to achieve smooth operation by means of the actuator and to ensure a functionally reliable design, it is also intended that the free end of the first lever is angled towards the backrest part.

It is preferably provided that the lever is angled at an obtuse angle.

For the same reason, it is intended that the ends

of the second lever angled towards the backrest ·

get lost. *····

It is preferably provided that both bends are obtuse-angled.

The corresponding lever design provides a kind of knee lever construction that ensures smooth operation, since the angle of the levers means that it is not possible to move the levers beyond the dead center, so that in every operating position a safe function for raising the backrest and simultaneously moving the

support part or to lower the backrest part and to simultaneously move the support part.

An embodiment of the invention is shown in the drawing and described in more detail below.

It shows:

Figure 2 also in an intermediate position; .· ·

Figure 3 also in an extreme position.

The drawing shows the main components of the · reclining furniture. Behind the ··'

In each of the loungers shown, a wall is indicated at 1, to which the headboard of the lounger is approximated.

The reclining furniture consists of a frame 2 fixed to the frame and a support part 3 arranged on the frame and longitudinally displaceable relative to it, whereby the support part 3 comprises, among other things, a pivotable upper support part 4, an adjustable lower leg part 5, an associated actuator 6, a non-pivotable middle part 7 and a

pivotable backrest part 8 with an additional adjustable headrest part 9. In the exemplary embodiment, the support part is essentially formed by a type of slatted frame.

The backrest part 8 is pivotally connected to the support part at 10 so that it can be adjusted from a flat position according to Figure 1 into an intermediate position and into a strongly upright inclined support position according to Figure 3. The support part 3, together with the elements attached to it, can be moved along the frame part 2 in the direction of the head end or in the direction of the foot end.

For this purpose, the frame 2, in the embodiment , *", has a head-side end area below the ·

Support part 3 at 11 a first lever 12 is hinged, ····

• · * whose free end, directed towards the foot part, is hinged at 13 on the backrest part 8 at a distance from its head-side end. Preferably, the hinge point 13 is approximately in the middle of the longitudinal extension of the backrest part 8. Furthermore, a second lever 14 is attached to the backrest part 8 at a distance from its head-side end, preferably also in the middle of its longitudinal extension, the free end of which, directed towards the foot part, is hinged to the support part at 15 near the end of the backrest part 8 directed towards the foot part, below the backrest part 8. On the frame 2

A linear actuator 16 is attached near the head end, the plunger 17 of which is adjustable in the longitudinal direction of the frame 2 and is articulated on the support part 3 via a bracket 18. The bracket 18 is also articulated on the articulation area 15 of the second lever 14. This ensures that when the plunger 17 moves from the basic position according to Figure 1, in which the plunger 17 is extended in the embodiment towards the foot part, in a working position according to Figure 2 and finally according to Figure 3 towards the head end, an upright swivel movement of the backrest part 8 and a superimposed displacement of the

support part 3 towards the head end. ·"*···

The end of the first lever 12 which is articulated on the backrest part 8 and the end of the second lever 14 which is attached to the backrest part 8 are arranged so that they can move along the backrest part 8. For this purpose, the end of the second lever 14 which is attached to the backrest part 8 is held so that it can move in a longitudinal guide rail 19 of the backrest part 8 and the end of the first lever 12 which is articulated on the backrest part 8 is articulated on the end of the second lever 14 or near the end of this lever and is thus indirectly connected to the backrest part 8. Both parts can thus be moved in the

Guide rail 19 can be moved without constraint when raising and lowering the backrest section 8.

To ensure the function, the free end of the first lever 12 is angled towards the backrest part, whereby the angle is formed at an obtuse angle. The ends of the second lever 14 are also angled towards the backrest part 8, whereby these angles also run at an obtuse angle. This achieves a type of toggle lever function that cannot be moved beyond the dead center in any position, so that the function is guaranteed in every case.

To stabilize the construction, an additional

Support lever 2 0 is provided, which is attached on the one hand to the ··"

·· ·* is hinged to the head end of the support part 3 and on the other hand to the backrest part 8, the hinge point being arranged between the rail 19 and the hinge point 10 of the backrest part 8. This stabilizes the entire construction.

The levers and the like shown in the embodiment are provided in pairs on both sides of the backrest part or the support part 3, with the actuator 16 being arranged centrally and connected to the levers via corresponding functional parts.

For this purpose, a cross member can be provided in the area of the articulation point 15, by means of which the movement of the actuator 16 is transmitted to the levers.

The invention is not limited to the embodiment, but is variable in many ways within the scope of the disclosure.

All new individual and combination features disclosed in the description and/or drawing are considered essential to the invention.
