Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a main body, a base plate of an adjustment fitting attached to a side wall of the main body, and a seat portion. Is held or articulated to the base plate via a metal part of the vehicle, and a foot support is provided. The foot support is connected to the base plate and the seat part via a second metal part. Therefore, when moving the seat portion from the base position of the seat furniture to the rear side, the foot support is swung, and a backrest capable of adjusting the inclination is provided.
An operating drive is provided, which is connected or articulated to the base plate and the seat part via the metal fitting part and is operated linearly by a motor for moving the seat part and for adjusting the tilt of the backrest. In this case, the actuating drive is supported and held by one end region on a cross bar connecting the base plates, and by means of the other end region, preferably by a push rod which can be carried out. The present invention relates to seat furniture articulated to a fitting part of an adjustment fitting.

[0002]

BACKGROUND OF THE INVENTION Seat furniture is well known in the prior art. In this case, the operating drive by means of a linearly acting motor is arranged centrally below the seat part. It is supported, on the one hand, by a bar connecting the base plate, preferably by its housing. The operating drive is articulated to the adjustment lever by the push rod,
This adjustment lever causes the adjustment of the seat part and thus the lifting movement of the foot support and the tilt adjustment of the backrest. The actuating drive acts in the center of the lever mechanism, but since the seat part is articulated on both sides by corresponding transmission members to the base plate, the adjustment of the seat furniture or its seat part is achieved. Occasionally, tilting can occur, which leads to impairment.

[0003]

Starting from this prior art, the object of the invention is to operate to a considerable extent without tilt by means of a centrally located operating drive under the seat part. The object is to provide seat furniture as described at the beginning.

[0004]

In order to solve this problem, the present invention proposes the following. That is, on the base plate,
One end of the first operating lever is articulated,
The other end of these operating levers is articulated directly via a second operating lever to a piece located below the rear end of the seat portion, and the first operating lever But,
Between the end articulated positions, they are connected to one another by a bar, from which a third rigid operating lever projects, which is located in the end region of the operating drive, in particular in this region. It is articulated to the push rod of the operating drive.

An operating drive, in particular its push rod, acts on a crossbar via a third operating lever, which is rigidly connected by its end to the first operating lever. Thereby, a synchronized movement of the transmission members is achieved, these transmission members being located below on both side edges of the seat part and having both base plates mounted on the side walls of the body. Work together. Therefore, during operation of the operating drive, no inclination of the transmission member occurs. In addition, a precisely synchronized drive for the transmission members arranged on both sides is guaranteed. Due to the design according to the invention of a rotating crossbar with a corresponding connecting element, a precise movement of the seat part firstly in the form of a translation and then for opening the backrest part is possible.

[0006] When the operation of the operation drive device is similarly reversed,
Thereafter, before the seat portion is moved forward and thereby the foot support swings, the backrest is first again tilted into the upright position.

BRIEF DESCRIPTION OF THE DRAWINGS An embodiment of the invention is shown in the drawings and will be described in more detail below.

In the drawings, only the main metal parts and functional parts of the seat part are shown. The seat furniture basically consists of a main body (not shown in the drawing), and a base plate 1 is attached to a side wall of the main body. The seat furniture has a seat part 2 which is supported or articulated on a base plate 1 via a first metal part 3. Furthermore, a foot support 4 is provided, which is connected to the base plate 1 and the seat part 2 via a second metal part 5,
Or they are articulated to them. In moving the seat part 2 from the base position according to FIG. 1 to the rear (to the right in the drawing) of the seat furniture, the foot support is swung from the base position according to FIG. 1 to the foot support position according to FIG. Is guaranteed. Furthermore, the seat furniture has a tiltable backrest 6, which is connected to the base plate 1 and the seat part 2 via a third metal part 7, or is articulated thereto, so that When the seat part 2 is moved further beyond the position according to FIG. 3 to the position according to FIG. 3, a tilt adjustment of the backrest 3 is performed. Finally, in the center below the seat part 2 there is arranged a linearly actuated operating drive 8 by means of a motor, by means of which the movement of the seat part 2 and thus the unloading movement of the leg support 4 and the backrest. 6 is performed. The operating drive 8 is supported and held by one end region 9 on a rigid cross bar 11 which connects the base plate 1 via an angle lever 10. The other end area formed by the removable push rod 12 is articulated to the fitting part of the adjustment fitting. At this time, the first operation lever 1
3 is articulated at 14 and the other end of these operating levers is directly connected at 15 to the rear of the seat part 2 via a second operating lever 16. It is articulated to a piece 17 located below the end. The first operating lever 13 is rigidly connected to each other by a horizontal bar 18 between the end-side articulated positions 14 and 15, from which a rigid third operating lever 19 projects downward. This operating lever is articulated in the end region of the operating drive 8, in particular on the push rod 12 of the operating drive.

With this configuration, a precise synchronous movement of the transmission elements on both base plates 1 mounted on the side wall of the body is achieved during operation of the operating drive 8 by the electric motor. When used as prescribed, no tilting occurs.

As is clear from the drawing, when operating the operating drive 8 from the basic position according to FIG. 1, first the third operating lever 19 is swung counterclockwise, whereby the first operating lever 19 is swung. The operating lever 13 is likewise rotated counterclockwise, and the second operating lever 16 causes the movement of the seat part 2 towards the backrest 6. The swinging of the leg support 4 is thereby achieved by means of a shear hinge 5 which is articulated to the seat part 2 or to the base plate 1. The rocking movement ends in the position according to FIG. When operating the operating drive further in the same direction, the tilt adjustment of the backrest 6 is then performed, with the rear end of the seat part being
Through the formation of the bracket at 20 only slightly, a forced tilt adjustment of the backrest 6 takes place against the spring force of the return spring 21.

The course of movement can be realized in the reverse operation of the operating drive 8 in the order of FIGS.

The present invention is not limited to the embodiments but can be variously modified within the scope of the disclosure.

All new individual and combined features disclosed in the specification and / or drawings are considered important to the present invention.
