• This mask can be used not only for skiing but also for motorcycles, or for any type of protection in general, especially during DIY work or for any industrial activity that requires eye protection.
• a skier's mask must be able to easily interchange a dark screen, protection against the reverberation of the sun on the snow, and a yellow screen improving the vision in case of fog. On existing masks, this interchange is not always very easy or very fast to achieve.
• the publication of patent application No. US 2013/091623 A1 describes a mask that can be used for skiing, comprising a base structure and a screen that can be mounted on this basic structure.
• the basic structure has a bearing face against the face of a user and, on the opposite side, a receiving face of the screen, and comprises an upper portion, intended to extend against the front of a user. user when the mask is worn, and a lower portion, intended to extend on the cheekbones and around the nose of the user when the mask is worn.
• the basic structure is made of an elastically deformable material; it has holes opening into said receiving face, at least two of which are arranged in said upper portion, and at least two others are arranged in said portion lower.
• Each hole has an internal enlargement, shaped to allow snapping, and the screen comprises at least four detent teeth, of reduced length, projecting from its inner face, that is to say from its side facing the face of the user when the mask is worn; these teeth are arranged in correspondence of the holes that comprises the base structure and are adapted to be inserted and retained in the corresponding holes to perform the mounting of the screen on the base structure.
• the present invention aims to overcome the aforementioned drawbacks.
• Its main purpose is therefore to provide a mask whose internal space can be easily ventilated when the mask is worn.
• Another object of the invention is to provide a mask whose handling is easy and fast, even with gloves.
• Yet another object of the invention is to achieve at least one of the aforementioned objectives with a mask whose structure remains relatively simple and easy to achieve.
• a further object of the invention is to provide a mask for achieving at least one of the aforementioned objectives and further allowing an easy and quick interchange of a screen by another screen.
• the mask concerned comprises, in a manner known per se, a basic structure and at least one screen that can be mounted on this basic structure;
• the basic structure has a bearing face against the face of a user and, on the opposite side, a receiving face of the screen, and comprises an upper portion, intended to extend against the front of a user when the mask is worn, and a lower portion, intended to extend on the cheekbones and around the user's nose when the mask is worn;
• the basic structure is made of an elastically deformable material;
• the base structure has at least four holes opening into said receiving face, at least two of which are arranged in said upper portion and at least two others are arranged in said lower portion; each hole has an enlargement set back from its opening;

• said hole comprises a second enlargement separated from said first enlargement
• said projection comprises at least a second enlarged portion separated from said first enlarged portion, said second enlargement and / or said enlarged second portion allowing said second engagement position to be a stable position of commitment.
• the invention thus allows the existence of at least two stable positions of engagement of the projections in the corresponding holes of the basic structure; in one of these positions, the screen is pressed against said receiving face; in another of these positions, the screen is positioned stably away from said receiving face, so as to form a ventilation gap between the inner face of the screen and the receiving face.
• a traction operated on the edge of the screen in the direction of the spacing of the screen relative to this receiving face allows to move the enlarged portions of the projections in the holes to the stable position in which the screen is kept at a distance from said receiving face;
• the ventilation gap thus arranged between the inner face of the screen and this receiving face allows efficient ventilation of the volume defined by the basic structure and the screen, account- given the large length that this gap presents and its presence on the whole, or a large portion, of the perimeter of the screen.
• the flexibility of the base structure and / or said projections allows that the upper part of the screen can be placed at a distance from the upper part of the basic structure while the lower part of the screen remains pressed against the lower part of the base structure, or vice versa, which allows two additional ventilation positions, in which the screen is inclined relative to the basic structure.
• said projections are all able to be extracted from said corresponding holes, so that traction exerted on the screen makes it possible to extract all said enlarged portions of the projections out of all the corresponding holes, which allows separation of the screen and basic structure, for easy and quick interchange of the screen. The installation of a replacement screen is thus performed just as quickly and easily.
