Description

Set formed by a helmet (1) and an air filtration system with integrated protective mask (2), especially for bicycles, skiing, motorcycles.

The present invention relates to a safety helmet (1) with a specified air filtration system with an integrated protective mask (2), more precisely with regard to the bicycle, ski, motorcycle helmet.

The assembly according to the invention is formed by a helmet (1) and a mask (2), it comprises a helmet (1) having an internal cap (3), an external cap (4), a mask (2) with two lateral edges (5), and an elastic retaining link (7) fixed on the helmet cap (3) and attached to the mask (2), this same mask (2) having a low position applied to the face of a user who wears the set and a high position or the mask (2) is applied against the cap of the helmet (3) using a suitable attachment system (Velcro® or other) (15).

It is characterized in that the cap (3) has at two spaced points a retaining clip (13) provided and adapted to retain the elastic link (7) and the mask (2) in the high position of the helmet and in the low position of the mask (2) applied against the face. By operating in this way the mask (2) is attracted against the face from attachment points (13) which are located on the internal cap (3) of the helmet according to the illustrated embodiment. This is not limiting and other attachment points can be created on the entire internal (3) or external (4) surface of the helmet.

The invention will be better understood by referring to the description below and to the attached drawings which are attached to it.

FIG. 4 illustrates the clipping of the retaining points (13) and the arrangement of the adapted hooking bands of the hook / loop type (15) known under the name of Velcro®, according to the construction method presented.

FIG. 5 illustrates the different characteristics and specificities of the mask (2) according to the manufacturing method presented.

-2 Referring to Figure 1, the assembly according to the invention comprises a helmet (1) and a filtration mask (2).

The helmet (1) is of any suitable type, and of any suitable shape. In the illustrated embodiment, it has two portions downward which cover the cheeks of its user. This is not limiting, and any other shape could be suitable, in particular these portions could be joined by a chin protection hoop, or the helmet (1) could have a bowl shape.

Conventionally, the mask (2) is intended to be used in two main positions, a low position where the mask (2) is applied against the face of the biker and a high position where it is applied against the cap (3).

The mask (2) is of any type, of any material, of any suitable form. According to the illustrated embodiment, the mask (2) conventionally has a generally rectangular frame, with folds (14) on the model presented in order to unfold it on the face, with two lengths (6), that upper with a flat nose bar (8) integrated in aluminum or any other material suitable for this purpose, in order to properly hold and press the mask (2) against the nasal wall of the user, and two widths (5) or edges side. Only the edge (5) is visible in the figure.

The mask (2) can have an opening (9) into which an anti-pollution filter (10) of PM 2.5, PM 10 or any other suitable type or filter category can be inserted in a suitable lining. On the illustrated model, this opening (9) remains closed using a Velcro® type attachment system. Any other type of closure adapted and corresponding to the required safety standards may be suitable.

The mask (2) comprises a link (7) retaining against the cap of the helmet (3).

The link (7) is connected to each of the lateral edges over the width of the mask (5). It is elastically stretchy. According to the illustrated embodiment, the link (7) is in two portions each connected to the mask (2). Only a portion (7) is visible in Figure 1 and will now be described. The other portion of the link (7) is identical.

The part of the link (7) is formed by an extensible elastic cord which describes a half-loop according to a high strand and a low strand. Each end of the cord (7) is attached to the mask (2) at insertion points (11) and (12) which are openings spaced across the widths of the mask (5) for a sheath (16) according to the mode illustrated. This is not limiting, and any other form of attachment could be suitable.

-3The cord (7) describes a half-loop, and it hooks towards the middle of its length on a point of return (13) which is fixed in the internal cap of the helmet (3). The reference points (13) form mask retaining clips (2) on the helmet (1). Under these conditions, the cords (7) exert traction on the mask (2) from the rear of the helmet (1) on the proposed model illustrated.

Referring to FIG. 3, the model of the point of reference (13) presented is in the form of a “spring clasp button”, commonly called a press button, the upper part of the male button (13), that in contact with the The user's skull, clipped into the female part (13), is padded, so that the synergy transmitted to the head is not strongly concentrated on this surface in the event of an accident. When the invention is not in use, a simple male button (13) without elastic and padded fastening is clipped so that no protruding metal part has contact with the skull of the user and conforms to homologation standards from the helmet manufacturer (1).

Also optionally the position of the reference points (13) can be modified, that is to say that they can be arranged in different places of the internal cap (3) or of the external cap (4) of the helmet (1). Of course, this construction method is not limiting and other construction methods could be adopted. In particular one could have reference points (13) whose end of the elastic link (7) would form a loop and would be wrapped around a padded button, or use a system of fasteners for staples, hooks and eyelets, or the elastic link sewn or inserted directly into the internal cap (3). In this case, the reference points (13) could be mounted directly on the internal (3) or external (4) cap of the helmet (1) or even be integrated in the internal (3) or external (4) cap at the time. of its manufacture (hooks, adjustable studs, etc.).

To adjust the tension of the cord (7) one could in this case equip one of its strands with a length adjustment system.

Consideration should also be given to a system for attaching the cord (7) to the mask (2), in order to be able to remove the mask (2) from the elastic retaining links (7) and be able to wash only the mask (2) or replace it by another by hooking it to the two elastic retaining links (7).

The present invention relates to a new design combination of safety helmet (1) for bicycle, ski, motorcycle and air filtration system with protective mask (2) integrated specifically to supply filtered air to the user. .

Various pollutions:

Studies show that air pollution is a major environmental and public health problem in industrialized and developing countries and is also considered to be

-4a contributing factor to stroke, lung cancer, and acute respiratory illnesses, including asthma. There has been a dramatic increase in the number of motor vehicles and other automobiles, thus becoming the main source of air pollution on the roads, which makes air breathable for road users.

The primary source of air pollution in large cities, the automobile accentuates and even develops diseases such as asthma and chronic bronchitis, particularly in the most fragile. It is also in our soot-spotted handkerchiefs that we become aware of the vulnerability of our respiratory system directly exposed to the finest particles that enter the lungs. For example, in Ile-de-France, road transport is the predominant sector in emissions of carbon monoxide (CO), nitrogen oxides (NOx) and fine particles (PM10) (Airparif, 09/2007 ).

According to the notre-planète.info site on November 24, 2016, air pollution causes the average premature death of 7 million people each year worldwide, including 600,000 in Europe and 45,000 in France, according to the World Health Organization and the Ministry of Sustainable Development. In France, the AFSSET (French Agency for Health and Safety for the Environment and Work) estimates that between 6,450 and 9,500 people died prematurely due to particulate pollution (PM2, 5) in 2002, more deaths than road accident victims (AFSSET, 05/2004).

According to the Parisian website of April 28, 2015, with 35% of global emissions, the transport sector is the leading emitter of carbon dioxide (CO2) in France with emissions which have gone from 110.7 to 120.4 billion tonnes between 1990 and 2011. In addition to CO2, the automobile releases other substances inhaled by bikers, some of which are more particularly dangerous for human health. Fine particles are among the pollutants in the air.

On French soil, the ADEME (('Environment and Energy Management Agency) reports that exposure to fine PM 2.5 particles (diameter less than 2.5 micrometers) reduces the expectation life expectancy of 8.2 months. As for PM 10 particles (diameter less than 10 micrometers), they cause 6% of premature death in France, according to the WHO (the World Health Organization). is attributed to road transport In addition to respiratory and cardiovascular diseases, studies have shown their harmful effect on reproduction and fetal and neurological development.

Another pollutant emitted at the exhaust, nitrogen oxides (NOx) grouping together nitrogen monoxide (NO) and nitrogen dioxide (NO2). Not only do they have an impact on global warming but the

Nitrogen dioxide (NO2) is in the form of an irritant gas capable of penetrating deep into the lungs. In France, road transport is responsible for 56% of NOx emissions.

Ozone (03) is also an aggressive gas that causes severe eye and respiratory tract irritation. Carbon monoxide (CO) is a cardio-respiratory toxicant. At low doses, it decreases the oxygenation capacity of the brain, heart and muscles. If volatile organic compounds (VOCs) have little direct effect, sulphates (SO2) cause respiratory discomfort, attacks of cough and asthma attacks.

According to the WHO, air pollutants cause 3 million deaths in France each year.

Cold :

Human beings have several mechanisms for regulating heat exchange in cold environments:

- Active protection against the cold: increasing the thickness of clothing, increasing the area covered by clothing ...

- The endogenous thermoregulatory physiological mechanisms, which involve the nervous, endocrine, cardiac and respiratory systems. The respiratory effects, in particular due to the cold air inhaled without protection of the respiratory tract during a journey on two wheels, are not negligible.

If it has long been recognized that respiratory illnesses increase in winter, the inhalation of cold air causes the lining of the upper respiratory tract to cool, which tends to inhibit infection-fighting mechanisms.

Several mechanisms have been invoked to explain the increase in respiratory pathology of infectious origin during the winter.

- The cold could reduce the immune resistance to infectious respiratory diseases. In addition, the inhalation of cold air triggers broncho-constriction, especially in cases of chronic obstructive pulmonary disease.

- In cold and dry weather, low humidity could dry out the mucous membranes and therefore reduce their resistance to infection.

- Cold, humid air is also a risk factor for asthma. Inhaling ice cold air is a trigger for asthma.

-6Dust:

The dust is bothersome and even dangerous for health. They can cause respiratory discomfort, allergies, lesions in the nose, lung problems.

Existing motorcycle helmets are mainly designed for safety against head injuries in road accidents and do not protect against inhalation of cold air, dust particles, air pollutants ... bikes, motorcycles use non-integrated respirators such as scarves, handkerchiefs etc ... which are not comfortable to carry and transport. There is a need for a safety helmet for two wheels not only safe from head injuries, but also against air pollutants on the roads, which will protect the user of two wheels against inhalation of dangerous pollutants .

Assembly formed by a helmet (1) and an air filtration system with flexible mask (2) of integrated protection, making it possible to protect the respiratory tracts of cyclists, skiers, riders of two wheels.

Indeed, in case of cold, dust, pollution, the pilots of two wheels place a scarf or bandana on the lower face during the journeys. This is not practical because you have to tie it and then secure the helmet (1) on your head. Often when it is necessary, the scarf or bandana is not available. The project consists of a flexible “mask” (2), for example made of fabric, with the option of integrating a particle filter (10) inside a fitted resealable lining (9), or else 20 two-layer microfiber or any other suitable filter material, retained by two elastic links (7), detachably connected to the helmet (13).

This "mask" (2) can take two positions: one in front, on the bottom of the face, the other, hidden in the bottom of the helmet, therefore on the top of the head, when the said "mask" (2 ) is not used. The links (7) in no way disturb this maneuver which is almost instantaneous.

The extra thickness is negligible at the bottom of the helmet (1).

In order to properly hold the "mask" (2) at the bottom of the helmet (1), there is provided a hook / loop type means (15) known by the name of Velcro®.

With the aid of the description which has just been given, the person skilled in the art will be able to realize other implications bringing about the effect which has just been described, without however departing from the scope of the invention which is determined. by the scope of the appended claims.
