Seating and reclining furniture with an adjustable back element that transforms into a seat, and the back element and the seat are coupled in the movement sequence.

Abstract

A seating and reclining furniture (1) comprises a frame (2) on which at least one seat element (4) and at least one back element (3) are mounted. These elements are connected via pivot points and sliding points by at least one control strut (5). This interdependence allows the furniture to be transformed into a reclining piece, thus creating a greater seat depth. It is advantageous that the seat element (4) and the back element (3) are connected via the control strut (5), meaning that only one element needs to be adjusted during movement, as they are interdependently connected.

Description

[0001] The present invention relates to a piece of seating and reclining furniture in which the seat, to which a backrest is attached, moves forward, creating a greater seat depth that can also serve as a reclining surface. The backrest is connected via a control strut so that when the seat is pulled forward, it is adjusted to a certain angle and can then also be used as a seat in its final position. All elements are positively guided, so the backrest is raised when the seat is pushed back. background

[0002] In practice, we're familiar with seating and reclining furniture where the seat can be pulled out from under the backrest, thus enlarging the seating area. The problem with this type of extension, the previously known extension, is that a strong backrest structure is required to generate sufficient seating forward. Task

[0003] The object of the present invention is therefore to create a piece of seating and reclining furniture that can be flexibly adapted to the user's needs and in which an extra-large seat depth can be generated from a piece of furniture with a standard seat depth. This feature is achieved in claim 1.

[0004] The seating and / or reclining furniture according to the invention comprises at least a base frame, a seat unit, and a backrest. When adjusted, the backrest can also lie flush with the seat surface, thus creating a larger seating area. The seating and / or reclining furniture according to the invention can consist of several seat units, with the width of the seat unit and the width of the backrest being independent of each other.

[0005] All elements can be upholstered.

[0006] The seating and / or reclining furniture according to the invention comprises a base frame (2) to which at least one guide device (8) is installed. This guide device can be linear or contoured.

[0007] Furthermore, the piece of furniture comprises a seat element (4) that is displaceably and / or pivotably mounted by at least one guide element (9), preferably four guide elements, which are mounted in the guide device (8). This can be achieved, for example, via sliding elements or roller guides.

[0008] The seat element (4) can be operated manually, for example, with a drive (linear drive), with a detent stroke actuator, or via a gas spring. These actuation options can also be driven via the back element (3) or the control strut (5), for example, since these components are interconnected. The entire movement sequence can be fixed in any position.

[0009] The back element (3) is connected to the pivot point a (6) so that it follows the movement sequence when the seat frame is operated.

[0010] At least one control strut (5) is located on the back element (3), which is rotatably connected to the back element via a pivot point b (7) and rotatably connected to the base frame via a pivot point c (10). This connection of the base frame (2), seat (4) including guide element (8), back element (3), and control strut (5) creates a dependency in movement.

[0012] In the Fig. 1 and Fig. 2 shows a view where the seat is not extended and the back is in a sitting position.

[0013] In the Fig. 3 and Fig. Figure 4 shows views of the furniture in its extended position. Here, the backrest is parallel to the seat, providing a larger seating area, allowing the furniture to be used as a lounger, for example.

[0014] In the Fig. 5 and Fig. 6 shows views in which the furniture is in an intermediate position and thus the movement sequence of the individual components can be seen.

Claims

[1] Seating and reclining furniture (1), with a frame (2) on which a seat element (4) and on which at least one back element (3) is arranged; wherein the back element (3) is dependent on the seat element (4) and the control strut (5). The seat element (4) can thus be adjusted in a depth-adjustable and / or pivotable manner and the back element (3) changes its inclination. This can be done up to the point of lowering, so that it can be used to extend the seat depth. This back element (3) can be adjusted to any angle. In order to move the back element (3) or the seat element (4) back to its original position, only a single element needs to be operated, since the elements are dependent on one another. [2] Seating and reclining furniture according to claim 1, characterized by, comprising a base frame (2) with at least one guide device (8), at least one seat element (4), at least one guide element (9), at least one back element (3), and at least one control strut (5).
