END; directed towards another additional part, as well as drive means connected to the free ends of the flaps to increase the total concavity of the support

The disadvantages of this support are:

- the complexity of the design, requiring manufacture in the factory;

-placing the support inside the back of the chair, which makes it an integral part and leads to more expensive seats;

- the ability to adjust the lumbar leaf lumbar

It is also known the seat of the vehicle {a „With No. 1757142 from 1990L2o18 B 60 N 2/00, publ. 2000 „04.10 o) r containing a pillow back and support elements installed with the possibility of movement on the pillow and back, characterized in that, in order to increase efficiency, the pillow and back are provided with transverse guides, and the support elements are installed in the said guides with the possibility of simultaneous asymmetric movement, which is selected as a prototype, the disadvantages of this seat include the fact that

supporting elements are an integral part of the back and seat cushion impossible "fitting the seat to a specific person (creating comfort) o

When developing this utility model, the task was to create a support providing a feeling of comfort in the entire back

The problem is solved by the fact that the following design is proposed: “The support for the back of the user containing the supporting elements differs in those; that the support contains a base and the rows of fastenings attached to it which must be at least one made of at least one tape of elastic material, while tapes are interconnected to form cells supporting elements are installed in the cells with the possibility of changing their number and location so that their surface, when viewed from the side, copied the contour of us a man sitting in a chair

It is preferable that the support for the back of the user is removable with the possibility of mounting its upper and lower parts to the chair in various ways

It is preferable to make the support and support elements of plasticized material

The utility model is illustrated by diagrams; where FIG. 1 shows a general view of a support; FIG. 2 shows a sectional side view along the attachment line “

The support for the back of the user contains a base to which two rows of fasteners 2 are attached, made of elastic bands 3 of which there must be at least one. The elastic bands are interconnected and attached to the base so that as a result we get cells into which the supporting elements 4 are made, made as and a base of plasticized material. The number and location of the support elements depends on the individual needs of the user.

The support for the back of the user is designed to be installed on the front of the back of the chair to which it is attached with its upper and lower parts in various ways o The support can be of different lengths: the entire length of the back of the chair or shortened, designed for the lumbar region

Interior design “In the proposed version (FIG. I), it is wider in the upper part (the support gradually tapers down and in the lumbar region it is essentially a support for the spine (without putting pressure on the unprotected lumbar organs

To create a beautiful appearance, this design is sheathed with any of the sewing materials used for furniture upholstery. On the back of the upholstery there is a hole providing access to the support elements to change their number and location; which, during operation of the back support, is closed in various ways, for example (, using lacing or zippers about

The support for the back is easy to use. The necessary relief is created experimentally. The support is fixed in the lower part of the seat and approximately filled with support elements. Then the support is fixed in the upper part of the back and “fitting” is carried out.

In accordance with his feelings, the user adds or removes support elements until he reaches the desired result

The proposed back support has the following advantages:

- since the support is removable, it can be easily removed without violating both the design of the chair and the overall interior design, and is easy to attach again;

- the support does not contain complex mechanisms, easy to manufacture and to use;

- It is possible to individually adjust the terrain of the support to create maximum comfort for the back of a person sitting o

The technical result achieved by using this utility model is the ability to be in a chair in a sitting position for a long time by adjusting the support for the back, which can take the form of a bend in the spine, which makes it more convenient to sit in the chair and partially relieve the spine, while maintaining posture
