The implementation of the invention

In Fig.1 shows the structure of a seat according to the invention. As shown in the drawing, two is Denia installed next to each other, forming a double sofa. The invention relates to the seat structure, which can be used as a main component in any furniture designed for sitting. The drawing shows only the body, seat and backrest. When used in chair or sofa are provided and sides, cushions, pillows, etc.

Design 1 seat includes a base frame 2, a back 3 and seat 4. Support frame 2 consists of four vertical plates forming a rectangular box with an open top and bottom. This base frame is designed for mounting components that make up the furniture, in particular the seat 4, the backrest 3, the legs 5 and so on, With each support frame includes first and second side elements 2A, b, and front and rear elements 2C, d frame.

Seat 4 includes a frame 6 of the seat, the spring 7 of the seat and at least one hinge mechanism mounting. In this embodiment, the frame 6 of the seat has a square shape with four sides formed by two essentially straight mutually parallel front and rear cross-beams 9a, b, one of which runs next to the backrest 3, and the other parallel to it, along the front side of the frame, and two angular or curvilinear mutually parallel side walls 10A, b. Springs 7 seat tightening frame 6 of the seat between the front and rear priest who uchinami 9a, b, forming a springy surface for pillows or so on the retention Mechanism is made of two hinged devices 8A, b mount installed on the lateral elements 2a, b for attaching the seat 4 to the base frame 2. In the embodiment shown in the drawing, the frame of the seat includes a third cross member 10C that extends beyond the perimeter of the seat frame at the ends of the specified cross suspended in the devices 8A, b mounting on a support frame. The fastening device made in the form of thrust blocks, made of a suitable material, in particular made of wood or metal, but preferably of plastic material. The cross member increases the rigidity of the seat frame. In an alternative embodiment to the frame of the seat can be attached to short lengths of pipe on which set of fastening device.

In the embodiment shown in the drawing, the device 8A, b devices are applied asymmetrically to the seat 4 relative to the Central axis passing through the seat, so the axis of the hinge will be held between the knees and thighs of the user sitting on the seat in a normal position, with your feet parallel and leaning back on the backrest. The fastening device can be installed, for example, at one-third the distance from the front of the seat. The objective of the invention is the location of the device is ist mounting thus, to ensure amoureusement fold back. The fastening device preferably does not contain stoppers or brakes, so the slope is limited to fastening devices and their location in combination with springs.

The clamping mechanism also ensures obtaining essentially horizontal position of the seat when the user is on it, and tilt the seat down in the back, when the user sits down. The seat tilts backwards, i.e. to the back, at an angle greater than 0 degrees, preferably from 0 to 10 degrees, more preferably from 3 to 7 degrees, from 2 to 6 degrees, from 4 to 8 degrees, or from 4 to 6 degrees and most preferably about 5 degrees relative to a horizontal surface.

Samorganizovatsya installation angle of inclination of the seat increases the feeling of comfort for the user in sitting and in supine position.

In Fig.2 shows a side view of the seat structure according to the invention, the side wall of the supporting frame removed. Curvilinear sidewall 10A, b include end part 11a, b, bent back outside the seat frame. End part 11a, b are located between the two end supports or surfaces 12, 13, which are below the backrest. End stops 12, 13 limits the angle of inclination of the seat 4, as the sidewalls are based on in which of rhny end stop 12 in the horizontal position and the bottom end stop 13, when the seat is tilted down toward the rear. However, the seat 4 can also stop in the intermediate positions between the end stops, if it provides balance to the user.

In Fig.4 shows a front view of the folding seat 4. In the seat structure shown on the left seat 4 has a slope down while the seat is in the design shown at right, is horizontal. One or more counterbalancing springs 14 mounted between the support frame and each of the sidewalls 10A, b or rear cross member 9b. If the seat is not loaded or not loaded to change the balance, balancing springs 14 are pressed seat 4, while holding it in a horizontal position. Thus the horizontal position means the unloaded or passive position in which the seat, if it is not busy. It should be noted that in the passive position of the seat may also have a pre-determined angle relative to horizontal.

In the embodiment shown in Fig.4, each end part of the side walls 10A, b are provided balancing spring 14. Spring is installed under the lower limit stop 13 and the terminal part of the sidewall, respectively. When the seat 4 is loaded, the part located at the rear, pressed and compresses the spring. Thus, the seat with some of the resistance which the group will be tilted down to the backrest 3. The user will have the impression of "immersion" in the seat, which will increase the feeling of relaxation and comfort. If the user wants to go (here we assume that the design of the seat is used in sofa, consisting of several seats, connected in series with each other), the weight distribution of the user on the seat 4 will change, i.e. the centre of mass of the user will be shifted such that the resistance of the balancing springs 14 will be pressed against the seat 4 up and restore the essentially horizontal surface of several of the seats, which will provide a convenient location, for example, for an afternoon NAP.

Instead of corner balancing springs, as shown on the drawings, you can use spiral springs, leaf springs or elastic elements. You can also use one spring disposed either in the middle of the rear cross member, or with a relative shift to the middle. Counterbalancing springs can also be placed in the mounting device and/or in combination with, for example, in the form of a torsion spring.

In another embodiment (not shown), the retention mechanism includes one or more hinges mounted on the seat (with its lower side, the said hinges are attached to the rod passing between the side elements of the support frame.

As is shown above, the design of the seat according to the invention can be used in several types of furniture. In Fig.6 shows the sofa, using the specified design of the seat. To the front of the seat to pivot points 17A, b attached to the hinged portion 16. The opposite end of the hinged portion attached to the base frame 2 at pivot points 18a, b of the fastening. When the seat 4 is tilted in one direction, the hinged portion 16 is tilted in the opposite direction, forming a fold in the surface of the seat and the bulge near the knees of the user occupying the sofa. If the user lies down on the sofa, the seat returns to a passive position, forming a straight continuous surface suitable for sleeping one person to seat multiple users or for partial support users on the sofa.

In Fig.7 shows the sofa with a seat 4 in the second position, where the seat is tilted down in the direction of the backrest 3. When the inclination of the seat back cross member 9b, the closest to the backrest 3, leans down, while the front cross member 9a nearest the hinged portion 16, leans up. Thus, the hinged portion 16 leans up near the seat 4 and is rotated around the hinge devices 18a, b of the mounting, with the hinged portion 16 and the seat 4 form an angle greater than 0 degrees. This situation is the meet place for example, when the user sits, leaning back 3.

Compared with the known solutions chaise longue or sofa according to the present invention differs in that the seat and the folding portion are connected at pivot points 17A, b and, in addition, have independent articulated suspension on opposite ends. Therefore, if the seat and the folding part of the bend, the entire Assembly must be extensible, to allow such a tilt. This opening is preferably provided in the hinge points 17A, b between the seat and the folding part. In the first embodiment, the hinges can be a conventional two-element joints with tubular ends for installation in the seat frame and the corresponding frame in the folding part. Each hinge can be attached to the first end to the frame and the other end is free to slide inside the tubular frame. Both ends can slide freely. Therefore, when the tilt of the seat frame up in the hinge points slightly move to the side.

However, it is preferable to implement each hinge point 17A, b in the form of an elastic hinge, shown in Fig.8A and 8b. He is a tubular body 19 of elastic material. The hinge has a biconical or tapered toward both ends and contains an annular ledge 20 in the middle. The hinge suppose the equipment fully or partially closed by a wall 21, located in the middle of the inner part of the tube. Such a hinge can just install as it is inserted into the tubular ends of the frames. The hinge consists of only one element and has good durability. In addition, it does not generate noise during operation.
