Description

Technical field

The invention relates to a new construction of an ergonomic seating position for positioning during a seated occupation.

BACKGROUND OF THE INVENTION

For activities where seating is preferable to other positioning methods (schools, offices, offices, etc.), ordinary office chairs and tables are used for seating and work. benches (school pupils). However, sitting on such chairs and behind regular tables causes minor or major health problems to anyone practicing it even a few tens of minutes a day. The problem of the present solution of this type of furniture (even the most flexible and equipped with various technically demanding accessories, such as adjustable height and inclination of the seat, armrests or backrest, or the work surface of the table) is insufficient adaptability to the needs and possibilities of the human body in various activities. The strain on the buttocks, sometimes on the elbows or the whole shoulders, but especially on the full length of the spine, causes temporary but increasingly permanent pain caused by unnatural stress on the spine (Fig. IA, IB - Spine loading and deformation while sitting, Fig. IC) while standing).

Another problem of the tables and chairs used to date is their low flexibility due to the individual peculiarities of the body size of the users. For example, the ergonomic chair known from EP 1 163 865 A2, consisting of a seat, a backrest and a frame with a rear segment, has only a height adjustable seat. The chair according to WO 00/05996 has, like the chair according to WO 01/76418 A1, not only the height of the seat, but also its inclination, as well as the backrest. However, even these elements do not cover sufficiently ergonomic demands due to the physical characteristics of the users.

Flexibility for physically disabled users has not been taken into account almost at all (rather, on the contrary, chairs and tables used to date cause health problems to about two thirds to three quarters of their users).

Attempts to address these problems have led to the creation of a knocker which partially relieves the buttocks and the lower back, but increased the load on the rest of the spine, arms and muscles by removing the backrest (one of the sources)

- 2 incorrect positioning when sitting down). The result is only a partial improvement, but it has worsened other seating parameters.

The optimal position for the human spine is - in addition to lying on an ergonomically correct mat - standing. At that time, the spine as a whole, but also the individual vertebrae and intervertebral discs, are loaded optimally, i. evenly and center of gravity and not uneven and eccentric.

It is an object of the present invention to provide such an ergonomic workplace for use in sedentary work that maximally eliminates the drawbacks of prior chairs and tables and contributes to reducing the health problems arising from the seating furniture used hitherto.

SUMMARY OF THE INVENTION

These deficiencies are eliminated by an ergonomic seating position for sitting position. The essence of the invention is that the ergonomic seating unit comprising a seating part is a structure comprising a seat, a torso rest, a work surface support and a working area part The seat-to-floor distance is 15 to 105 cm and the distance between the seat construction and the rests are 10 to 33 cm. The fuselage restraint is equipped with means for attaching and adjusting the work surface and also has a supporting function. It can carry, for example, lighting.

The seating station further comprises at least one calf support and / or knee support and / or a foot support. The seat and the torso support may be connected to each other, the seat preferably having a calf support and / or a knee support and / or a foot support.

According to a further embodiment, the seat, torso and calf support and / or the knee support and / or the footrest may be separate or optionally equipped with at least one element for attachment to the outer structure. The position of the separate armrests (torso, calves, knees, feet) can be fixed by means of an external supporting structure. Preferably, the torso support, which is preferably width adjustable, is provided with at least one head restraint and at least one fastening element for attachment to the support structure.

- 3 The seat, calf support and / or knee support and / or footrest may be fitted with a common fastening element for attachment to the supporting structure. A supporting structure in this sense means a wall, ceiling or floor.

The ergonomic workstation structure of the present invention may advantageously be made of steel tubes or light alloy tubes of different diameters. The seat can be made of perforated sheet, laminate, plastic, wood or braided. The footrest can be made of solid sheet or perforated sheet, or a wooden grate.

The ergonomic seating unit of the present invention distributes the user's load evenly across multiple parts and areas of the body such that overall stress is not harmful to health, even physically or mentally uncomfortable. Part of the body (ie part of the body's weight) is supported by the calf or (alternatively) knee (similar to the kneeling), part by a recess between the shoulders and the body or head (forehead, chin). This relieves the butt and it is not desirable and possible to rest your elbows on the worktop.

Just the possibility of leaning the fuselage respectively. hull and head is a major advantage of the present invention. All this minimizes the load on all parts of the human body, but especially the spine from neck to coccyx, which allows a completely new quality of positioning, which not only harms, but even remedies the already damaged or tired back.

In addition, the ergonomic seating position allows easy and easy adjustment of the height and tilt of the worktop according to body conditions and type of work from horizontal to almost vertical for people with a height difference of up to about 40 cm at the same ergonomic seating position. This allows the needs of the entire population to be optimally addressed using four to five sizes of the workplace. This is mainly due to the fact that the distance x (see Figures 1 and 2) is one of the most stable and least changing distances of the human body during its growth, but also between different individuals of the same height. Therefore, differences in this dimension between high and low respectively. between adults and children are minimal, although extreme body variations are not excluded. In such a case, the ergonomic seating station offers a correction by adjusting the position of the worktop by fixing the sleeves on a section marked which may optionally be equipped with stops as shown in Figures 5 and 6.

The distance of the seat 1 from the floor was 72-73 cm, the gap between the construction of the seat 1 and the armrest 2 was 24-25 cm.

Example 2

The ergonomic seating station according to FIG. 15 for a height category of 135 to 175 cm was made of metal tubes of two diameters by bending. The lower part of the structure (i.e., the structure carrying the seat 1, the calf support 5 and the knee support 6) is made of steel tubes of larger diameter than the upper part of the structure supporting the fuselage support 2, with means 4a and 4b for fixing and adjusting the work surface 3. Seat i was made of laminate.

The calf support 5 and the knee support 6 were made of plastic strings (flexible plastic hoses with a diameter of 4 to 6 mm, possibly wrapped with fabric) between the tubular construction of the footrest. The means 12 for adjusting the width of the fuselage restraint 2 were formed, as in Example 1, by two pairs of metal strips which were fixedly attached to the workstation structure, approximately in the region of the shank and the shoulders of a sitting person.

The working area 3 of the ergonomic workstation consists of a wooden board with a plexiglass-filled cut-out enabling the monitor of the personal computer to be viewed. The plate was adjustable by means of means 4b as in the previous example, provided with a thin cable passing through the upper part of the fuselage support 2. The ergonomic workstation was further equipped with a monitor of a personal computer made of strip steel.

The distance between the seat and the floor was 61 to 62 cm, the gap between the construction of the seat 1 and the fuselage rest 2 was 15 to 16 cm.

Example 3

The seat of FIG. 14 is similar to FIG. 15 but was made by welding steel tubes. Due to the strength, the welds in the corners where they are most stressed were reinforced. The hull supports 2 are not, in this embodiment, equipped with means for adjusting their width. If the seat is designed for lower figures (up to approx. 170 cm), it is not necessary to adjust the width of the body rest 2

- 6 wooden grates and ergonomic workplace was further equipped with means for storing office supplies.

The distance of the seat I from the floor was 61 to 62 cm, the gap between the construction of the seat 1 and the fuselage support 2 was 15 to 16 cm.
