FIELD OF THE DISCLOSURE

[0001] The present invention generally relates to helmets. Particularly, the present invention relates to trauma resistant anti ballistic helmets.

BACKGROUND

[0002] Helmet is a protective gear worn on a head portion of a user to protect it from injuries. Helmet may be used for various purposes such as recreational activities, sports, two-wheelers occupant, construction, mining, police and military applications. The Police, military and other law enforcement agencies personnel wear the helmet to protect their head from hand held firearms/Hand-guns, high velocity fragments, projectiles and the like. It is important that the helmet should cater to the needs for which it is used.

[0003] Helmets used for Police, military and other law enforcement agencies should protect their head from trauma (Back face deformation (BFD)) that can be caused by various elements such as hand held firearms Hand Guns, high velocity fragments, projectiles, stones, blow and the likes. Trauma (BFD) is an important consideration while designing ballistic protection articles. More the amount of trauma (BFD) more is the chances of users getting injured. Generally, a trauma (BFD) head injury is more fatal than trauma to other parts of the body.

[0004] Presently, helmets that are used for head protection (particularly, for

Police, military and other law enforcement agencies) are made of different types of ballistic fabrics such as Kevlar fibers or from Ultra high molecular weight polyethylene Polyolefene fibers. Further, shells of helmets are molded under pressure and temperature till it cures and adopts the shape of mold. Thereafter further operations such as cutting to required shape, fitment of harness assembly and applying protective paint in the required shade is carried out,

[0005] -Although, the currently existing helmets are useful for security forces, paramilitary forces and other law enforcement agencies, the currently existing helmets have various limitations. For example, the currently existing helmets are eom. ar lively less effective in providin trauma resistance to the operative front portion, the operative rear portion and the periphery of the helmet. Further, the currently existing helmets are comparatively less effective in providing trauma resistance to head portion, of a user from snipers, enemy fire and other harmful projectile.

[0006] Accordingly, based on the foregoing, there exists a need for a helmet that provides comparatively more protection to an operative front portion, an operative rear portion and/ a. periphery of the helmet, Further, there is need of a helmet tha is comparativel more effective in providing trauma resistance to a head portion of a user from snipers, enemy fire, projectiles, stones and the like..
