Description

Technology area

The claimed invention is intended to provide a comfortable sitting position for a long time. Refers to the furniture industry, in particular to the production of structural elements for chairs and stools; special devices for chairs, stools, car seats.

As you know, prolonged sitting on an ordinary piece of furniture for sitting or a car seat can lead to excessive pressure on the coccyx, which can lead to the formation of an epithelial coccygeal passage (coccyx cysts), compression of the pelvic organs and organs of the reproductive system, with restriction of their normal blood supply and , as a result, cause disruption of their functioning. In addition, people with injuries to the back, coccyx, and thigh bones experience severe discomfort when using conventional seating furniture.

State of the art

The closest analogue of the claimed invention is the ORTHOPEDIC PILLOW SELIVANOV (PM No. 134767). Orthopedic pillow, containing a cover of upper and lower fabrics and filler, while the upper and lower fabrics of the cover along the working surface are additionally connected with each other by a line with the possibility of forming symmetrically to the vertical axis of symmetry of the central and single side hollow sections with holes for filling with filler, and the thickness of the filled the central section is less than the thickness of the filled side section, characterized in that the central section has a U-shape with the possibility of forming a neck roll from the side section at the bottom and fixing the user's head located in the central section on the sides. This cushion can be used as a seat cushion, but its main disadvantage is the inability to adjust the rigidity and height of use. These disadvantages limit the range of consumers of the above-mentioned device and all consumer properties are aimed at satisfying a narrow circle of people, in contrast to the claimed device. PM No. 134767 (new.fips.ru).

There is a known solution MIKHAILOV'S ORTHOPEDIC SEAT, which is a universal structure that includes a seating element consisting of two halves located at a distance from each other, a support for a seating element, in a particular case, it can have a back and / or armrests, for example, a stool, chair, pouf, car seat. Seat support elements should be understood as any elements, including those mounted on legs that support the seat, for example, drawers, leg mounts, car seat runners, car seat base frame, etc. The seat includes two halves running along the side side bars of the base, located at a distance from each other in the range from 50 mm to 100 mm inclusive. This distance is optimal for a comfortable long sitting, during which there is no squeezing of the legs of the seated person, while there is no danger of falling between the halves of the seat, and the pressure on the tailbone, on the pelvic organs and on the organs of the reproductive system is reduced. The distance between the halves of the seat is selected according to the age and size designation. The disadvantage of this solution is the limited use, due to the rigid attachment of the halves of the seat to the supports. This leads to the impossibility of using the demonstrated system on different elements of the interior, but is tied only to one specific object, for example, a chair. In addition, the device does not have the ability to adjust for the individual physiological characteristics of the user, in particular the rigidity and height of the pad.

Disclosure of invention

The main objective of the claimed invention is the development of a mobile design of an orthopedic pad, with the possibility of using it on various objects for seating with an additional function that allows you to adjust the height and rigidity, adapting it to the physiological needs of any user, which will cover a wider audience of consumers, in contrast to similar products on the market.

The tasks are achieved by manufacturing the structure as a separate additional module in the form of a lining, with the constructive possibility of adjusting the rigidity and height to any element for the seat.

The U or U-shaped orthopedic seating pad is not rigidly fixed FIG. 1-4. Both of these shapes have two ends and a bar.

The U-shape is suitable for chairs in which the front edge of the seat is at right angles to the side edge, and the U-shape is for chairs in which the seat has a more rounded front edge. In this case, the pad, regardless of its shape, can be used on pieces of furniture with any shape of the seat surface. The shape of the overlay has no influence on the final technical result.

The pad is installed on the seat with the ends (2.1) of Fig. 3 towards the rear edge of the seat and the crossbar (2.2) towards the front edge.

The cover in all versions has a cover (2.3), at least one layer of polyurethane foam (2.4) and at least one air chamber (2.5) with a pear-shaped pump (2.5.1) with a button-valve (2.5.2) depressurizing FIG. 12.

In the first embodiment, the claimed patch (2) of FIG. 1 includes a cover (2.3) and a combined U or U-shaped filler, consisting of at least one layer of polyurethane foam (2.4) - the bottom layer and the top layer in the form of a single air chamber (2.5), laid on the bottom.

In the second embodiment, the claimed solution of FIG. 2 includes a cover (2.3) and a combined filler in the form of two rectangular parts, each of which consists of at least one layer of foamed polyurethane (2.4) - a lower layer and an upper layer in the form of an air chamber (2.5).

The parts of the combined filler to form a U or a U-shaped patch are united by a cover (2.3) of FIG. 2, which has two niches for the filler and a crossbar (2.2) in the form of a bridge between them on one edge.

Due to the two parts with the filling, there is no distortion in the case when the user presses on one of the buttocks more strongly. In addition, it is possible to adjust the pressure of the chambers in different ways, which in some cases is necessary, with different development of the gluteal muscles or preventing the skew of the spinal column, etc.

The overlay (2) in all versions, in a particular case of execution, can have several ¹ (1 SEVERAL - more than one; two, three or more; Ideographic Dictionary of the Russian Language. - M .: ETS Publishing House. Baranov OS .. 1995. ) layers of homogeneous polyurethane foam with the same or different degrees of rigidity.

Due to the difference in stiffness and due to the design of the filler from two parts, it is possible to adjust the stiffness and height of the pillow by changing the position of the hard and soft layers or by removing them from the overall structure.

In all versions of the solution, pumping and bleeding of air from the air chambers (2.5) can be carried out by the user both during installation and while sitting on the pad (2). For pumping and bleeding the air are responsible for the output from the air chamber (2.5) of Fig. 1, 2 rubber pear-shaped pump (2.5.1) with a button-valve (2.5.2) of pressure relief.

In all versions of the solution, in a particular case, the cover (2.3) at the location of the pump may have a loop-shaped pocket (2.3.1) of Fig. 1, 2, located at the end of the lining (2). When the pump is not required, it fits into the loop-shaped pocket (2.3.1).

Cover (2.3) of the cover (2) fig. 1, 2 is made of durable wear-resistant elastic material. In special cases, the version is made of ventilated and / or antibacterial and / or abrasion resistant fabric.

The cover (2.3) follows its contours and has a hidden technological opening for access to the inner filling of the lining (2). The hole can be additionally equipped with fasteners. The cover can additionally have anti-slip elements on the underside of the pad (2) in contact with the seat to prevent slipping on the chair, or it can be made of a material with the same property.

Also, the cover (2.3) has holes (e) for the output of the pump (s) (2.5.1) for option 1 - one hole, for option 2 - two holes.

For careful operation and durability of the product, as well as camouflage, the presented solution in a particular case in any of the versions can be equipped with a wear-resistant protective cover (3) FIG. 4.

Protective cover (3) fig. 4 is a cape with adjusting straps (3.1) that allow you to shape the cover (3) by tightening, depending on the piece of furniture on which the cover (2) is installed.

As a result, the claimed solution allows the user not only to avoid health problems associated with prolonged sitting, but also improves the emotional state during operation, due to increased comfort, which consists in the ability to adjust the height and rigidity of the pad during operation, adapting it to physiological needs.

Principle of operation

To implement the claimed solution in all variants, a cover (2.3) of FIG. 1, 2 of ventilated and / or antibacterial and / or abrasion-resistant fabric with a hidden technological opening for access to the niche (s) for storing the filler and an opening for the pump outlet.

For the first embodiment, FIG. 1 prepare a U-shaped or U-shaped cover, polyurethane foam filler (2.4) and an air filling chamber (2.5), repeating the U-shaped or U-shaped cover (2.3). Next, a layer of polyurethane foam (2.4) is placed in the niche of the cover (2.3) through a hidden technological hole and a chamber for filling with air (2.5) is placed on top of it. If a hidden technological hole has a fastener, it is closed.

For the second embodiment, FIG. 2 prepare a U-shaped or U-shaped cover having two niches for laying the filler, and a crossbar (2.2) connecting them to each other. Prepare a polyurethane foam filler (2.4) and air-filling chambers (2.5) each in the form of two rectangular pieces. Next, a layer of foamed polyurethane (2.4) is placed in the cover (2.3) in each of the niches through a hidden technological hole and a chamber for filling with air (2.5) is placed on top of it, and the pump (2.5.1) is brought out through the hole. If the hidden technological holes have a fastener, they close it.

The finished pad (2) according to any of the options is placed on the piece of furniture that will be used for sitting, while the ends of the pad (2.1) in FIG. 4 are positioned to the rear of the seat and the crossbar (2.2) to the front of the seat. Further, the user uses the piece of furniture with the installed pad (2) in the usual way.

If an inconvenience in the height or rigidity of the lining (2) is detected, the user has the opportunity to increase or decrease the pressure of the air chamber (2.5) located inside the cover (2.3). To do this, by means of a pump (2.5.1) and a valve button (2.5.2), it pumps or bleeds air in the chamber (s). In case the cover is used with an additional cover (3) of FIG. 4, then after installing it on a piece of furniture, for example a chair (1), it is covered over with a protective cover (3), which is pulled by straps to maximize the tightness of the seat with an overlay (2).

If the pad according to any of the options is equipped with a large number of polyurethane layers (2.4), then the required number of layers is installed in the cover (2.3), and in case of inconvenience, in terms of height and / or rigidity, the user removes or adds layers of filler through the technological hole , of the same or different degrees of rigidity.

In case the user wishes to change a piece of seating furniture, he transfers the overlay (2) to a new piece. If a protective cover is used, then to transfer it to a new piece of furniture, first remove the protective cover (3) by loosening the slings (3.1), then transfer the cover (2) to the new piece of furniture, and install the protective cover (3) over it.
