[0028] The essence of the utility model is explained by drawings.

[0029] Fig. 1 shows a side view of an office chair with a folding canopy.

[0030] Fig. 2 shows the rear view of an office chair with a folding canopy.

[0031] The drawings indicate: 1 - arc, 2 - armrest, 3 - awning, 4 - hinge, 5 - back, 6 - seat, 7 - bolted connection, 8 - shock absorber, 9 - legs, 10 - wheels, 11 - visor. An office chair with a folding canopy 11, containing (Fig. 1) at least two arcs 1, mounted with a base on a hinged joint 4 of the chair, for example, to the back 5 or armrest 2 or seat 6 of the office chair, as well as an awning 3, fixed, for example, with a seam or glue, if materials made of polyethylene, polyester or the like will be used on the arcs 1 and protecting the worker from noise, exposure to the sun, oncoming air flows from the air conditioner and drafts, includes an armrest 2, a seat 6, a back 5, a shock absorber 8 and legs 9 with wheels 10.

[0032] Armrests 2 are rigidly fixed to seat 6 and back 5 of the chair, or only to seat 6, using bolted connection 7. Under seat 6 there is shock absorber 8, fastened with one side to seat 6 of the chair, and with the other side to legs of the chair 9. Wheels 10 are located on legs 9 of the chair. Fastening of legs 9 of the chair to shock absorber 8 and wheels 10 to legs 9 is made with the possibility of rotation around its axis.

[0033] The arcs 1 are made, for example, U-shaped (Fig. 2), their fastening to the chair occurs due to the hinge joint 4, located on the armrest 2, or the back 5, or the seat 6, allowing folding, unfolding, and also adjusting the tilt of the canopy 11, the base of the canopy 11 is the outer arc 1, connected to the frame of the back 5 of the chair. To improve the mobility of the structure, each subsequent arc 1 from the base of the canopy 11 is located higher than the previous one. The minimum distance between the ends of the arc 1 corresponds to the width of the seat 6 of the chair, the distance between the arcs 1 is determined depending on the material of manufacture of the arcs 1 and the thickness of the awning 3, so that the canopy 11 can be folded without hindrance.

[0034] Additional rigidity of the canopy 11 in the unfolded state is provided by the awning 3, which stretches when the canopy 11 is unfolded, fixed at least on two extreme arcs 1, for example, by a seam. The execution of the arcs 1 with an increase in the height of each subsequent one, starting from the base of the canopy 11, allows the hinged joint 4 to fold the canopy 11 into a plane with the backrest 5 of the chair, or a diagonal, when the hinged joint is located on the seat 6, going from the place of attachment on the seat 6 to the top of the backrest 5, without interfering with the use of the armrests 2, and without hindering getting on and off the chair. The hinge joint 4 is made, for example, in the form of a pin located on the armrest 2, or the backrest 5, or the seat 6, on which the hinge mechanism is placed, having an opening for placement on the pin on one side, and an opening for placement of the bases of the arcs 1 on the other. To be able to fix the visor in any intermediate position in the hinge joint, a lock is used.The folding canopy 11 can be attached to an office chair in different ways:.

[0035] - Can be made in a monolithic version, in which case it is a continuation of the armrests 2 or the back 5 of the chair or seat 6.

[0036] - Can be attached from the outside to the armrests 2, backrest 5 or seat 6 of the chair.

[0037] - Can be attached to the back of the 5 chair from the side or to the rear part of the back with screws, glue or other fasteners.

[0038] - Can be made in a removable version, when the hinged joint 4 of the folding visor 11 is inserted into tubes (grooves, holes) or placed on pins (protrusions) fixed to the armrests 2 or to the back 5 or to the seat 6 of the chair.

[0039] It can be made in a quick-release version, when the structure of the folding visor 11 is fastened with the edge of the awning 3 to the backrest 5 with a zipper, rivets, Velcro, buttons, hooks with loops or is fastened with harnesses, ties, clamps, rubber bands or other methods, and the hinged joint 4 is placed on the armrests 2, the backrest 5 or the seat 6 with the help of a quick-release joint, which is a mating part located on the armrest 2, the backrest 5 or the seat 6, and the housing of the hinge mechanism, which has the ability to be fixed in the mating part and removed by pressing a button located on the mating part of the quick-release mechanism.

[0040] Awning 3 can be made from various materials: general-purpose fabrics, technical fabrics, special fabrics (heat-insulating, sound-insulating, sound-absorbing, acoustic, antistatic), polyethylene and other polymer, polyester materials.

[0041] The material of the awning 3 can be either transparent or partially or completely opaque.

[0042] The material of the awning 3 can be of different density and thickness.

[0043] The arcs 1 can be made of various materials - metal, plastic, carbon fiber, polymer, composite, wooden and others, in the form of rods, reinforcement, tubes, plates with different cross-section profile shapes. The awning 3 can be equipped with side inserts located from the edge of the canopy 11 to the armrest 2 or seat 6, and covering the user of the chair from the side from the back 5 to the extreme point of the canopy 11, as well as a front insert located on the extreme arc of the canopy and covering the user of the chair from the front. The technical result declared in the utility model is achieved due to the fact that the office chair contains a folding canopy, providing cover for the user from above and on the sides and an awning, attached to the canopy frame, and protecting the user of the chair from the effects of oncoming air flows from the air conditioner, drafts, noise and the sun.The use of a seat in a chair provides the softest landing of the chair user and provides the most comfortable working conditions for the employee. The use of a backrest in a chair provides the correct position and angle of the back of the chair user and provides the most comfortable working conditions for the employee. The use of a shock absorber in a chair provides shock absorption and vibrations when getting on and off the chair, provides seat height adjustment and provides the most comfortable working conditions for the employee. The use of wheels in a chair allows the chair to be easily moved and provides the most comfortable working conditions for the employee. All of the above reduces the stress level of the chair user when working in the office.

[0044] The arched design of the canopy allows the canopy to be divided into sections and allows the canopy length to be configured based on the needs of the chair user. The canopy can be folded using a hinged joint located on the body of the chair, which allows the chair user to fold, unfold and fix the canopy in an intermediate position based on the employee's current tasks, which reduces the stress level of the chair user.

[0045] The technical result is also affected by the declared range of awning material density of 100-700 g / m 2, this range is explained by the sufficient density of the material to reflect air flows, noise and sun, which reduces the stress level of the chair user. Exceeding this range will lead to the weighting of the structure and a decrease in the convenience of mounting the visor on the chair, folding and unfolding the visor during use, which will negatively affect the user's stress level. The use of a material of lower density will not provide sufficient protection for the user, which will negatively affect the user's stress level.

[0046] The technical result is also affected by the thickness of the awning material in the range of 0.2-10 mm, this range is explained by the sufficient thickness of the material to reflect air flows, noise and sun, which reduces the stress level of the chair user. Exceeding this range will lead to a heavier structure and a decrease in the convenience of mounting the visor on the chair, folding and unfolding the visor during use, which will negatively affect the user's stress level. The use of a material of lesser thickness will not provide sufficient protection for the user, which will negatively affect the user's stress level.

[0047] The technical result is also affected by the execution of the arches of the canopy with a thickness of 1-15 mm, this range of thickness is sufficient to ensure the stability of the structure when using different thicknesses and densities of the canopy awning material, which reduces the stress level of the chair user. Exceeding the specified range will lead to the weighting of the structure and a decrease in the convenience of mounting the canopy on the chair, folding and unfolding the canopy during use, which will negatively affect the user's stress level. The use of a smaller thickness of the arches will not provide sufficient reliability of the canopy frame, which can lead to its fracture during operation and will negatively affect the user's stress level.

[0048] The test of the office chair with a folding canopy was carried out in accordance with the embodiment examples given below and consisted of assessing the stress level of users of the office chair with a folding canopy before using the chair and 20 days after using the office chair with a folding canopy, during which a social survey was conducted, showing that using the chair reduces the stress level indicator by an average of 17%.
