DESC:Brief Description About The Invention Present invention relates to a secured ballistic helmet with provisions for better fitment and adjustment of helmet on head of user. More particularly present invention relates to a ballistic helmet with harness and dial type adjusting mechanism without in any way compromising with structure and ballistic integrity of helmet shell.
Background of Invention: A combat helmet or ballistic helmet is a type of head gear, a part of personal armour which is designed to protect the head of user during military/or similar combat operations.
Today's armed forces often use high quality helmets made of ballistic materials such as Kevlar or Aramid /High molecular weight polyethylene and hybrids, for enhanced personal protection from projectiles fired by hand held weapons, splinters and fragments. Some helmets also have good non-ballistic protective qualities, against injuries caused by concussive shock waves caused by explosions in operation zone. Ballistic helmets need idiosyncratic fastening and retention systems to allow the soldier (user) to comfortably wear a helmet and at the same time hold the position of helmet on head during movement of user, during fall, impact of bullet/projectile or during para-jumping. Most of the combat helmets have been designed for modern warfare requirements and also act as a platform for mounting cameras, video cameras and VAS Shrouds for the mounting of Night Vision Goggles (NVG) and monocular Night Vision Devices (NVD) / Visor .
However, when we mount such modern operational gadgets over the helmets, this makes the helmet unstable and creates hindrance to the user during operations. In view of this it is important to keep the helmet firmly anchored to the head in place with added accessories and for this purpose fastening and retention system with dial ratchet play a vital role. Helmets used in World War-1(WW-1) model M1917 helmet were made of steel and consisted of a very basic and simple leather strap that fits under the chin with adjustments for
tightening/loosening. These helmets did have a leather liner, for comfort and sweat absorption. However, these helmets were not snug fit and had the tendency of toppling during the operations. Subsequently, after WW-1 lot of work was carried out for further improvement and advanced combat helmets and modular integrated communication helmets were introduced with H-Harness. This chinstrap system had 4 points attachment, with a chin cup, and H shape - nape around of the neck with many adjustment points. In modern war zone its required to attach multiple accessories to the helmets but the extra weight of these devices brings in uneven weight on the outer surface of helmet and a resultant tendency to make the helmet unstable and may even cause the helmet to slide over the forehead of user blocking eye vision of user. This type of hindrance is not at all acceptable. Besides, it also required the user to keep readjusting the Helmet frequently because the harness (fastening system) did not have adequate adjustment/fastening. For giving more stability to a ballistic helmet, dial type adjusting/fastening mechanism (Ratchet) has been introduced which helps in tightening//loosening the helmet around the circumference of the head for better comfortable and secure fit of helmet in place. These dial type adjusting mechanism (Ratchet)keeps a helmet stable and in place. Besides, it has the most convenient feature and that is, single point adjustment system. In all the conventional ballistic helmets, harness and dial type adjusting mechanism (Ratchet) is attached to the inner side of helmet after making hole(s) in helmet shell. Patent document number US9743701B2 tells that, in certain embodiments, a fastener is received through a hole in one or more of the straps to attach the strap directly to the helmet shell.
However, point which is to be noted is that hole made in ballistic helmet shell to attach harness and dial type adjusting mechanism (Ratchet) which makes the ballistic helmet vulnerable against the possible ballistic threats in the warzone.
Object of invention:
To develop :-
A. A ballistic helmet which is more secure for users in war zone. B. A ballistic helmet with harness and dial type adjusting mechanism (Ratchet) without compromising the structure of shell by making drilling hole in the helmet shell. C. A ballistic helmet without hole(s) in the shell with provision for fitment and adjustment of ballistic helmet. D. A ballistic helmet without hole(s) in the shell with provision for secure deployment of Modern warfare devices like cameras, video cameras and VAS Shrouds for the mounting of Night Vision Goggles (NVG) and monocular Night Vision Devices
(NVD) / Visor.

The main embodiment of the present invention is to provide a ballistic helmet with provisions for NVG shroud, or any other Similar Provision without making hole/ holes for mounting shroud for night vision devices, goggles binoculars, monocular, video camera, still camera, recorders, visors, face shields and all types of helmet mounting devices. Present invention relates to ballistic helmet with harness and dial type adjusting mechanism without any hole in helmet shell. In prior art (fig No. 1) clearly shows that to fix the harness with the ballistic helmet hole and screw assembly (6), however this arrangement makes ballistic helmet unsecure for users in war zone from the point at which hole is made in helmet shell. Figure 2 shows ballistic helmet with harness and dial & ratchet type adjusting mechanism without any hole in helmet shell. The solution is based on fixing /adhering the harness and dial & ratchet type adjusting mechanism with the inner side of helmet shell without making any hole in shell. It Shows that ballistic helmet has got shell (1), hole-free area of shell (2) where harness (5) is having dial & ratchet type adjusting mechanism (3) that adjusts around the circumference of the head to help keep a helmet in place, along with chin strap (4) is suitably attached with the inner side of shell; and for attachment, holes and screws are not used which provides uncompromised safety of user in battle field. Figure 3 shows that inner view of ballistic helmet with harness and dial & ratchet type adjusting mechanism without any hole in helmet shell. In one of the embodiments adhesive has been used to attach the harness (5) and dial & ratchet type adjusting mechanism (3) along with chin strap (4), with the inner side of shell (1).
In another embodiment epoxy based adhesive has been used to attach the harness (5) and dial & ratchet type adjusting mechanism (3) along with chin strap (4), with the inner side of shell (1). This is to be noted that degree of threat will less to user of present invention as there are no holes in shell; as the holes made in shell to attach harness and other attachments create weak-pockets in the ballistic helmet so ultimately the safety of user is compromised.
