Aug. 20, 1963 H. N. KHANBEGIAN HOOD OVER-ALL Filed July 18, 1961 F" .1. an?
INVENTOR l@ ATTORNEY U/zanbegian States The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.
The invention relates to adjuncts to protective helmets such as are worn by military personnel, reman, industrial workers and others requiring protection of the head. Specically the invention relates to such helmets which include a head band and cradle in radially inwardly spaced relation to the helmet shell.
Such head bands provide a roughly annular space around the wearers head through which drafts enter the shell to the inver-ted bowl-shaped space around the wearers head above the cradle. This feature is highly desirable in hot weather on account of the cooling of the head which results therefrom. However, it is highly undesirable in cold weather for obvious reasons.
With the foregoing in view, it is an object of the invention to provide improved means for preventing cold drafts trom entering the interior of the helmet.
A further object is to provide in such a device improved means for protecting the areas of the face and neck below the helmet from cold.
A further object is to provide such a device which is readily retracted to a semi-inoperative position atop the helmet.
A further object is to provide such a device which is readily applied to and removed from a standard protective helmet without any modification of the same and without the use of special tools or skills.
Other objects and advantages reside in the `speciiic structure of the invention and/ or the combination of the same with a protective helmet, all of which will be readily apparent to those skilled in the art upon reference to the attached drawing illustrating one species of the invention and to the `following specification wherein the invention is described and claimed.
In the drawing:
FIGURE 1 is a front elevational view of the device applied to a helmet;
FGURE 2 is :a side elevational View thereof;
FIGURE 3 is a transverse vertical sectional View taken substantially on the plane of the line 3--3 of FIGURE 2; and
FIGURE 4 is a longitudinal vertical sectional View taken substantially on the plane of the line 4-4 of FIGURE l but showing the invention inthe semi-inoperative position.
Referring specifically to the `drawing wherein like reference characters designate like parts in all views, designates generally a helmet liner or the like such as the military Ihelmet illustrated which is supported upon the head of a wearer by a radially inwardly spaced headband 11 such as that disclosed in the Riddell Patent No. 2,250,275. Such headband 11 supports any suitable cradle 12 which may conform to that disclosed in the Grancsay etal. Patent No. 2,758,306. As is readily app-arent in FIGURE 4, headband 11 and cradle 12 provide an inverted bowl shaped space 13 wherein air normally circulates. To prevent cold outside air from entering such space 13 outside of headband 11, there has been provided the protective hood 14 according to the invention.
The hood 14 comprises a generally tubular body of any suitable iieXible material which is substantially impervious ICC.
to the passage of air or drafts rand which is provided at its upper end with a exible ladjustable means 15 such as a 'drawstring or elastic band for removably securing the same about the outside ofthe helmet liner .16. A second flexible yadjustable means 16 likewise entends entirely around the hood 14 in downward spaced relation to the means 15. This second adjustable means 16 likewise may comprise anelastic band or a drawstring and is located just Ibelow the brim of the helmet liner 1G. -It has a close t with `the head of a wearer whereby to close the annular space outside ofthe headband 11 and prevent the entrance of outside air to the space 13. `Below the second adjusting means 16, the hood comprises a tubular curtain portion 17 having a lower `edge 1S preferably formed with athird iieXible adjustable meansfor providing a close t with a wearers neck.
A face opening 19 is formed in the front of the curtain 17 and Athe upper margin of `such opening is defined by a portion of the second adjustable means 16. The remaining margin of the face opening 19 is deiined by a substantially U-shaped edge 20 of the curtain 17 which edge is formed as a tunnel and contains an elastic or drawstring for tightening the opening about 4a wearers face to prevent entry of drafts therethrough to the interior of the helmet and hood.
To insure that the hood 14 is properly supported, there has been provided a hood cradle which corresponds to the `liner cradle 12 and which comprises three or more crossing straps 21 which have their lower ends 22 in equispatial arrangement around the hood and which ends are sewed or otherwise secured to the hood 14 in the region of the `second adjustable member 16 inwardly thereof. The central portions of the straps 21 are crossed in the region of the top of a wearers head and are slidably connected together by a keeper 23 as in the `cradle of the Grancsay et al. patent aforesaid. The hood cradle straps are located inside the headband 11 and cradle 12. This arrangement insures that the second adjustable member 16 is drawn into close engagement with the periphery of a wearers head in the region of and juist below the headband 11. Thus, there needs to be but a minimum of ladjustment of such means `16 if it is a drawstring or if it is an elastic band, lthe same can be comparatively weak whereby there is no danger of cutting oli or unduly reducing circulation of yblood to the head. Thus, a comfortable iit is assured merely by properly adjusting the length of the cradle straps 21 in the manner of the Grancsay et al. patent aforesaid.
FIGURE 4 illustrates the use of the device when circumstances do not require the use of the curtain portion 17 orf the hood. Here the curtain 17 is rolled or folded upwardly until it is entirely around the liner lil. It is secured in such a position by the third adjustable means 1S in a manner readily understood.
it follows from the foregoing that the hood according to the invention can be applied to and removed from any standard protective helmet without any modiiication of the latter and without the use of any special tools or skills. Moreover, -while there has been shown and described what is now thought to lbe the preferred embodiment of the invention, it should be understood that the same is susceptible of other forms and expressions. Consequently, the invention is not considered to be limited to the precise structure and design shown except as hereinafter claimed.
The combination with a protective helmet including a helmet shell having a headband therein in radially inwardly spaced relation thereto to provide a substantially annular air 4space therebetween; of a protective hood for said helmet, said hood comprising a portion adapted to engage the outer surface of a helmet shell engaging portion, a
to provide a close t with a wearers head whereby to close said annular air space bet-Ween said headband and shell, a face opening in said curtain between said annular adjustable means and said lower edge, said face opening including an upper edge defined by a portion of -said annular adjustable means, said face opening having opposed side edges connected by a lower edge to provide a `substantially U-shapedv edge, fa substantially U-shaped adjustable means included in said U-shaped edge to provide a close t with |the face of a wearer, curtain straps secured to said annular adjustable means inwardly thereof, said curtain straps being adapted to extend upwardlyl -within said helmet land over a wearers head for supporting said hood thereon, said [curtain straps being operative to draw said annular adjustable means into engagement with a `wearer@ head just below said headband.
