Description
Barzano & Zanardo HELMET
The present invention relates to a helmet, particularly protective helmet for work or sports.
The object of the present invention belongs to the field of helmets, headpieces and/or similar safety protective headgears which can be used during the performing of dangerous and risky activities, such as those carried out in construction sites, mines, oil platforms, by fire-fighters, by first aid providers, by mountain climbers or those carried out in any field where it is necessary to protect the head of the users.
The object of the present invention is also suitable to be applied in the field of sports helmets, such as for example those intended for cycling, horse riding, skiing and for any other sports activity requiring the use of helmets.
As known, protective helmets for work generally comprise a structure having at least one convex outer surface and at least one concave inner surface adapted to receive in engagement the head of a user.
The inner surface of the helmet structure is usually equipped with a protective body made of a material suitable for shock and impacts absorption, such as polystyrene.
Generally, the protective bodies of the aforementioned helmets are made by molding in a single polystyrene monobloc which has a predetermined density on all parts of the protective body.
The protective bodies are usually engaged to the helmet structure by means of special interlocks so as to be removable if necessary.

The helmet according to the present invention solves the problems observed in the known technique and achieves important advantages.
First of all, through the coupling mechanism the engagement between the protective body and the helmet structure has excellent stability.
It should also be noted that the coupling mechanism allows the assembly or disassembly of the protective body on the helmet structure in an easy, simple and rapid way.
Furthermore, the coupling mechanism between the protective body and the helmet structure allows for an easy and effortless adjustment of the height of the protective body, giving the helmet itself greater adaptability to the size of the user's head. Depending on the size of the user's head, the height adjustment of the protective body prevents the structure of the helmet from reducing the visibility of the user wearing the helmet.
