Description

The utility model relates to the clothing industry of light industry and can be used to protect the head and face, namely, to protect the respiratory organs and protect the head from fire, cold, and aggressive polluted air.

A respirator head mount is known that includes a headset and a mask base. The latch of the head mount allows you to remove the belts from engagement with each other and translates the head mount into a folded position, in which the mask can be kept in a state that is removed from the face, it is convenient to place the headset of the respirator on the user's neck when the base of the mask is removed from the face / Pat. 2523998 Russian Federation, IPC А62В 18/02.

The disadvantage of the invention is the discreteness of adjustment, which reduces the possibility of an exact fit, since the design of the headset lacks an elastic element to ensure maximum fit. The placement on the face, the tightness and accuracy of the fit provided by the front straps can cause the user to grip the hair, in case of non-grip hair - unfastening the head mount. Adjustment of the straps does not imply the presence of a helmet, and will be complicated and practically impossible inside the helmet.

However, the possibility of using a protective helmet by users with various anthropometric data of the head and individual features of the appearance can be ensured only if it is carried out with dimensions that obviously exceed the head sizes of the intended user. With such dimensions, a protective helmet, originally worn on the head with the eyeglass assembly opposite the eyes, moving away as a result of the user's movements, will inevitably occupy a position on the head in which the slit for the eyes will be shifted relative to the user's eyes. This leads to a narrowing of the already limited field of view, which in conditions of poor visibility when the user is in a fire zone, accident or disaster, the air of which contains smoke, dust and fog, significantly complicates the operation of the protective hood. Another disadvantage of the described device is the difficulty of adjusting the tightness of the mask, carried out inside the head helmet, and the inability to ensure a tight fit on the head and face in the presence of glasses and a voluminous complex hairstyle.

The technical result of the utility model is to increase the reliability and effectiveness of protecting the head and respiratory organs of a person by ensuring the stability of the helmet in the respiratory organs of the face, neck and head, taking into account the individual configuration of the head.

The specified technical result is achieved by the fact that in a protective helmet against aggressive media, made of two types of fire-resistant material, the upper part is made of a transparent polyimide film, and the lower part is made of a fire-resistant woven material containing a mask, pelerine and means for securing the mask, according to the utility model, part of the helmet in the region of the nasolabial-chin part is made congruent to the spatial shape of the scoop, the fastening means of the hood is made either in the form of a curtain with an elastic element covering the goal ovu in the lower occipital part with the possibility of regulation, a brace in the neck area with a fastener on the Velcro tape in front and an elastic spacer plate between the wings and the brace, or a double curtain that covers and additionally fixes the nose and chin parts of the suction pad, passing at the level of the side surface of the head and having a common adjustment point on the outside of the back of the helmet; in the upper part of the helmet, between the side seams, there is an elastic link.

In the forehead region of the protective helmet between the side seams are two horizontal reflective strips, and in the center of the front, excluding the field of view, is a vertical stripe.

For example, rigilin is used as a spacer elastic plate located at the back between the wings and the strap.

The means of attachment in the form of an elastic curtain on the outer surface of the helmet with the possibility of unobstructed outside adjustment of the fit of the mask and the helmet as a whole, prevents the penetration of air between the half mask and the face of the user, which helps to increase the protective properties of the hood and the effectiveness of protection. The construction of the helmet in the region of the respiratory organs of the face in a congruent spatial shape of the suction pad eliminates the helmet shifts in the process of orientation on the head when donning, the presence of an elastic link in the form of a loop, effortlessly put on the back of the head, prevents the helmet from slipping as a result of the user's movements when turning the head. The use of an elastic spacer plate located between the horizontal link and the strap in the back of the neck supports the frame structure of the respiratory device, fixes the attachment of the suction pad in a predetermined position, eliminates the shift of the hood during operation. This provides additional fixation of a given helmet landing on the user's head, reliable fixation with respect to protruding parts (voluminous hairstyles in the form of a tail or a bundle, arches of glasses, etc.) for ease of use, which means that the helmet is clearly oriented in the lower part of the face, neck and head and ease of use. In addition, the use of two horizontal retroreflective strips in the forehead between the side seams and one vertical in the center of the front (excluding the field of view) allows the user to be more noticeable in conditions of increased smoke in front and side.

Thus, the proposed design of the helmet contributes to the overall stability of its landing on the face and head of the user and, therefore, increases the reliability and effectiveness of the protection of the head and respiratory organs. Therefore, it ensures the achievement of a positive effect and the implementation of the task.

FIG. 1 - helmet protective from aggressive environments, located on the person’s head and in the use position, front view;

FIG. 2 - the same side view;

FIG. 3 - a helmet protective from aggressive environments with a double wings, including elastic elements, front view

FIG. 4 is the same side view.

Protective helmet 1 from aggressive media (Fig. 1, Fig. 3), made of two types of fire-resistant material: the upper part of the helmet is made of transparent polyimide film 2, and the lower part 3 is made of woven material in the nasolabial-chin part 4 is congruent spatial in the form of a suction cup 5 with a non-return valve 6 (Fig. 2, Fig. 4) with a front seam 7 that passes to the drape 8. At the back and sides of the lower part 3 at the level of the suction cup 5 there is a helmet fastener in the form of a wings 9 with an elastic element inside (not shown) covering the head at the bottom th occipital part, and a latch 10 to adjust the tightening density. In the neck area, a strap 11 is made to fix the helmet 1, in front its ends are fastened on a Velcro tape. An elastic spacer plate 12, for example rigilin, is vertically placed between the backstage 9 and the strap 11.

For ease of attachment and increase the tightness of fit in the claimed tool provides another option for fixing the helmet 1 in the neck, namely the implementation of the double wings (Fig. 3, Fig. 4), which consists of: the wings 9, fixing the nose part of the suction pad, passing on the level of the side surface of the head and the additional curtain 13, fixing the chin part of the suction cup, located from the chin to the back of the head and having a common control point 10 on the outside of the back of the helmet.

In the upper part 2 of the helmet, between the side seams, there is an elastic link 14 in the form of a half-belt.

In the forehead area of the helmet 1 between the side seams are two horizontal reflective strips 15, and in the center of the front, excluding the field of view, is a vertical strip 16, in the region of the suction cup - over the seam 7.

Structurally, the rocker 9 is located as close as possible (butt, lap) to the suction pad. An elastic element (in the form of an elastic braid or strip of thin rubber) inside the wings 9 and 13 has a width of the order of 3 ... 5 cm, which increases its reliability and durability and eliminates pressure on the head when wearing a helmet, minimizes discomfort and twisting during dressing, increases convenience , provides a fairly snug fit of the suction pad in the nose-chin area of the user. The elastic element on the outside has a width sufficient for threading into the latch 10. This can be an elastic or inelastic cord. Between themselves, two different in width elastic elements of the wings 9 and 13 and the latch 10 are connected by an integral seam. The design of the wings 9 and 13 and the presence of the latch 10 located at the rear on the outer surface of the lower part of the helmet enable simple adjustment and quick individual adjustment of the product for different sizes of the head and face contours, quick putting on / removing the helmet in an emergency in the proposed device.

The length of the elastic wings 14 in the form of a half-belt is equal to the semi-girth of the head of the smallest adult size. Dressing is carried out by throwing a loop on the back of the head. The user without increased tension can move the elastic half-belt 14 to a comfortable position even on the run, without grabbing hair, scalp, as the half-belt glides over the surface of the film 2. The excess volume of the helmet 1 is redistributed. This ensures additional fixation of the given helmet fit on the user's head (fit), which means reliability and ease of use.

A sufficient amount of space in the scalp and eyes contributes to the convenience of using the headgear by people with glasses, hairstyles (braids, bows, etc.).

The device operates as follows. The user puts the helmet 1 on his head through the hole in the lower part 3. Holding with one hand the part of the helmet 4 congruent to the scrubber 5 and fixing it in the area of the nasolabial-chin part, with the second hand he adjusts, if necessary, the protruding parts of the hairstyle, and then holding the regulator with one hand 10, pulls with his other hand his elastic braid (cord) from the outside of the rear surface of the helmet 1 to the state of maximum fit contours of the suction mask 5 to the surface of the face. The degree of tension of the elastic braid inside the wings 9 and 13 should ensure the tightness and tightness of the fit of the suction pad, without forming naminas on the surface of the user's skin. Then the user with both hands grabs the two halves of the elastic strap 11 from the back, circles them around the neck in front and fastens the front with an overlap on the Velcro tape, until the drape fits snugly around the neck. Having adjusted the protruding elements of the hairstyle (such as a tail, a bun, etc.), he throws an elastic half-belt 14 on the back of his head, fixing it in a position convenient for himself.

Thus, the configuration and device of the helmet: the presence of its outer side in a special way arranged and creating the possibility of matching the product to the individual sizes of the user's head, elastic wings and a strap, specially designed design of the nasolabial-chin section, made congruent to the spatial shape of the mask and the surface of the lower part of the face, and the location of the reflective strips, - all elements of the claimed configuration provide the necessary tightness of the fit submass chnika, fixing stability of the helmet on the head, a light detection in human conditions of reduced visibility, and thus contribute to improving the reliability of its protective properties.
