"Adjustable armchair"

The invention relates to a changeable in three mutually different positions Yerstellsessel with adjustable seat inclination and adjustable seat angle as well as with a via a known linkage when adjusting the seat from the first position in Aie second position or reversed from the seat adjustable footrest, with the crouch being hinged to the seat on one side and on both sides the back is each provided with a swing, with which the back on the other hand the frame is articulated and supported, furthermore on both sides of the Seat each awei spaced one behind the other, limited pivotable swing are provided, the upper end parts are hinged to the seat and the lower end parts with are articulated to a seat frame held on the chair frame, and the seat rocker arms in the sitting position of the armchair from their lower articulation parts at an angle in front in the other two armchair positions, however, about upright respectively. obliquely backwards

i with a hook arranged on each of the rear fawn wings 1st, which is supported in the seated position of the chair fen a frame-fixed stop, While he releases the stop in the other two armchair positions and with All joint axes are arranged at right angles to the seat depth.

In an adjustable chair of this type known from DE-OS 28 11 360, its improvement Is sought with the invention, the seat linkage consists of two together scissor-like, articulated joint rods, of which the first rod is hinged to the frame with its rearwardly directed end part is, while the second rod with its forward-facing end part on the frame both longitudinally adjustable as well as pivotable about an articulation axis. Furthermore, one of the rocker arms carrying the seat is on the free end parts of both rods hinged.

The object of the invention is now with prevention the cost of materials for the seated bar and ease of assembly options for even easier adjustment of the armchair in its adjustable positions as to create so far.

The solution to this task is characterized by the following features:

a.) the seat rockers are each by means of two, extending between the latter and approximately toggle-like through articulated lever connected to each other ^

b.) the levers are approximately in the middle of their longitudinal extension on articulated bolts that are fixed to the frame mounted so as to be pivotable about this j

c.) the seat rockers are each on the approximately opposite lever arms the lever hinged}

d.) in one of the mutually directed lever arms the lever is a lengthways thereof arranged extending elongated hole, in which one on the adjacent lever arm of the other Lever arranged hinge pin engages limited adjustable along the elongated hole and

e.) both mutually facing lever arms of the levers are supported in the seated position of the Armchair on stops that are fixed to the frame.

This eliminates the need for materials compared to the subject of DE-OS 28 11 360 for in each case one of the articulated rods connected to one another in a scissor-like manner, from which a not inconsiderable one This results in a reduction in dead weight and material costs.

In addition, the armchair can now also be moved smoothly from the 3rd to the 2nd position lead back.

It is advantageous if the engaging into the long hole hinge pin carries rotatably mounted and this abwäizbare to the elongated hole edges role in wines. In addition, it has been found to be advantageous if the lever arms of the levers, which are roughly opposite one another, are longer than their lever arms, which are roughly directed towards one another.

In addition, an advantageous design of the above-described object is characterized by releasably arranged hinge pins.

In this way, in the event of any wear and tear on the hinge pins, the hinge pins can be replaced in order to restore the original, easy-to-use adjustment option, in contrast to the prior art, the hinge pins being designed as bids.
In addition, the assembly of the ßessel is also made much easier.

An embodiment of the invention is shown in the drawings, and is described in more detail below. Show it

1 shows an adjustable armchair in longitudinal section, in the sitting position,

FIG. 2 likewise in the second position, FIG. 3 likewise in the third position.

Here are on both sides of a chair seat 1 and the back of the chair 2 to the A frame plate 4 each attached to the inside of frame cheeks 3, which by means of a Traverse 5 are connected to each other.

The seat 1 and the kicker 2 are connected pivotably about the axis 6. Zxidem is provided on both sides of the back jje a rocker 7, whose one end part on kicking 2 and the other ! End part hinged to a frame plate 4- 1st.

On each frame plate 4, two hinge pins 8 and 9 that are fixed to the frame are arranged. On each bolt 8,9 is a two-armed Lever 10 respectively. 11 pivotably mounted, the short lever arms 12 respectively. are hinged together. For this purpose, an elongated hole 14 running in its longitudinal extension is provided in the lever arm 12, in which a hinge pin 15 striving transversely from the lever arm longitudinally of the elongated hole 14 engages adjustable. On the hinge pin 15 is one to the Flanks of the elongated hole rollable roller 16 rotatably mounted.

At the each other about Gegenge th, long lever arms 17 respectively. 18 is one each the seat 1 supporting rocker 19 respectively. 20 hinged, the upper end parts of which on the seat are hinged.

3) The rocker 19 is on its lower pivot axis 21 extended and with a J-footrest rod 22 known per se connected, which carries a footrest 23.

On the rocker arm 20 is then on the hinge pin 24 ·, the latter with the Lever 11 articulated, a hook 25 directed approximately towards the back 2 is formed, the bolt-shaped one that struts from the mounting plate 4 and is fixed to the frame Stop 26 corresponds.

In the sitting position of the armchair (JFig 1) are the levers 11, 12 pushed up and their long lever arms 17> 1ß supporter: yourself on the traverse 5 and on the stop

away. In addition, the stop 26 engages in one this adapted hook recess 27 a · If the seat 1 is now relative to the frame 3 by the person sitting in the armchair Adjusted at the rear, the seat rocker arms 19120 swivel upwards at an angle from their previous position and front-facing position backwards (according to Pig. 2).

The footrest 23 is influenced by the rocker 19 forward into the Pivoted position of use. At the same time, the hooks swivel forward, influenced by the seat rocker 20, that only the long lever arms 18 of the lever 11 are on the stops 26 support.

The seat 1 and the Stoop 2 has been inclined slightly backwards.

If the seat 1 is further adjusted backwards by the person sitting in the armchair, and that relative to the frame 3 », the seat rockers 19, 20 pivot into those in Pig. 3 position shown.

This inevitably has the effect that, on the one hand, the footrest 23 is even wider than before (Fig. 2) exposed to the front and at the same time raised even further.

On the other hand, the levers 10, 11 buckle down and limit the pivoting movement the seat swing 19.20 »But the hooks 25 are also at the front where pivoted woerden, the latter, however, the stops 26 constantly reach under and rest on the latter to determine the preselected chair position and the intended reclining position in the second respectively. to ensure the first chair position. The third chair position is the same as with known object according to DE-OS 28 11 of the seat 1 and the backs 2 further after has been tilted back. ·

To convert the armchair into the second or first ßselposition takes place in reverse Series.

At one end, four hinge pins are used to fix the hinged hinge parts in the axial direction of Seeger-einge or similar. Organs to detach the hinged parts, especially to facilitate assembly .

This measure also enables the entire transmission, in particular for transport to be able to decompose what the transport space requirement and the need for Packaging material can be reduced.

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