BACKGROUND OF THE INVENTION This invention relates to an impact absorbing pad for use in conjunction with the neckband of a helmet shell to prevent or minimize injury to the base of the skull of the wearer of a helmet when the helmet is subjected to impact from the rear.

The Armed Forces have for many years used helmets to protect the heads of soldiers against missiles, shrapnel, and the like. A helmet is usually made of a metal having high impact and ballistic resistance within which a helmet shell is worn, the helmet shell usually being made of relatively hard plastic, often reinforced with fiberglass. Inside of the helmet shell a helmet shell suspension is mounted. The helmet shell suspension is made of flexible webbing materials arranged to fit the crown of the head of the wearer of the helmet and thus keep the helmet shell spaced somewhat away from the head of the wearer. Usually thereis .a chin strap to be passed under the chin and fastened to the helmet shell suspension on both sides of the head to prevent the helmet shell from tilting backwards on the head. Also,

- there is a neckband which is fastened to the helmet shell suspension on both sides of the head and passes around the base of the skull in the rear, usually contacting the nape of the neck, and serving to prevent forward tilting of the helmet on the head. Such an arrangement is disclosed in US. Pat. No. 2,814,043 and will under most circumstances provide adequate protection for the head of the wearer. However, it has been found that in the case of parachute jumps occasionally a soldier lands off balance or may be dragged by a parachute and thrown to .the ground with great force. If this occurs and the rear edges of the helmet shell or helmet are jammed against the neck and base of the skull, there is grave danger of severe or even fatal injury-to the parachutist.

It is, therefore, an object of the invention to provide an impact absorbent pad for use with a helmet shell to provide protection to the nape area of the neck and the base of the skull against the effects of severe impacts on the rear portions and especially the rear rim of a helmet shell or helmet. Other objects and advantages will be apparent from the following description of one embodiment of the invention, and the novel features will be particularly pointed out hereinafter in connection with the appended claims.

SUMMARY The invention comprises an impact absorbing pad to be mounted on the neckband of a helmet shell suspension system so as to be held between the neckband and the area at the base of the skull of the wearer to prevent the back rim of the helmet shell or the back rim of the helmet from strikingagainst the neck or base of the skull of the wearer with damaging force when the helmet and helmet shell are subjected to impact from the rear.

skull of the wearer 21 of the helmet DESCRIPTION OF THE PREFERRED EMBODIMENT The drawing shows the preferred embodiment of the invention.

In the drawing:

FIG. 1 is a perspective view of an impact absorbing pad embodying the invention, the pad being viewed from a position to the rear and somewhat to the right side of the wearer if the pad were being worn in conjunction with a helmet shell.

FIG. 2 is aside elevational view of a helmet shell on the head of a wearer thereof, including an impact absorbing pad embodying the invention, the impact absorbing pad being viewed in perspective and from the left side of the wearer. The helmet shell suspension has been cut away except for the lower portion of the headband to which the neckband is attached, the neckband and a suspension strap supporting the impact absorbing pad against the base of the skull of the wearer.

FIG. 3 is a rear elevational view of a helmet shell as in FIG. 2 on the head of a wearer thereof, including the impact absorbing pad embodying the invention, the impact absorbing pad being viewed from the rear thereof. As inFIG. 2, the helmet shell suspension has been cut away except for the lower portion of the headband to which the neckband is attached on both sides of the helmet shell, the neckband and a suspension strap supporting'the impact absorbing pad as in FIG. 2. Lower portions of the chin strap are also cut away for convenience.

Referring to the drawing, wherein like characters designate like parts in all views, 10 designates generally the body of an impact absorbing pad embodying the invention. The impact absorbing pad, when in use, is generally in the shape of an inverted T. It comprises a fabric envelope 11 within which a T-shaped sheet of expanded closed cell cellular elastomeric material, such as material known as Ensolite" and manufactured by Uniroyal, Inc., is inserted; and the fabric envelope is closed by a seam 12. The sheet of expanded closed cell cellular elastomeric material provides resiliency and impact absorption characteristics to the impact absorbing pad. Its thickness is such as to provide adequate cushioning for the nape of the neck and base of the skull of the wearer against impact by the lower rear rim 13 of the helmet shell 14 in the event of an incorrect parachute landing fall in which'the back of the helmet would strike the ground jamming the rear rim of the helmet shell against the nape of the neck and base of the skull of the wearer. The impact absorbing pad is provided with two straps l5, usually made of webbing, sewnor otherwise attached to the envelope on the rear surface thereof and along the two side edges of the rear surface so as to form two substantially parallel spaced apart loops 16. Neckband 17 is flexible and usually made of webbing, is adjustable in length, is fastened to headband 18 by a rivet19 on eachside of the helmet shell, and is threaded through loops 16, providing support for the crossing portion 20 of the inverted T- shaped impact absorbing pad against the base of the shell. A flexible suspension strap 22, preferably made of webbing, is attached at one end thereof to the neckband l7 approximately midway between the points of attachment of the neckband to the headband on the two sides of the helmet shell, passes upwardly across the base portion 23 loops 16 may be made wide enough or the suspension strap 22 may be made wide enough to prevent any possibility of the shifting of the impact absorbing pad along the neckband l7 and toward one side or the other of the head of the wearer. In any case, the loops 16 and the suspension strap 22 should be made wide enough to insure that the pad remains in close contact with the nape area, thus insuring that if the lower rear rim 13 of the 'helmet shell is forced in the direction of the skull and nape of the neck of the wearer, it will strike only the impact absorbing pad. Thus serious injury due to' concussion at the base of the skull will be prevented when the impact absorbent pad is provided with a sufficiently thick sheet of expanded closed cell cellular elastomeric material within fabric envelope lland the pad is properly installed in cooperation with the neckband and the helmet shell, as illustrated in FIGS. 2 and 3. Chin strap 25 under normal conditions under which a helmet shell is worn prevents backward tilting of the helmet shell. However, it is unable to prevent the rear rim of the helmet shell from striking the nape area or base of the skull if the helmet and helmet shell are impacted with great force from the rear. The impact absorbent pad prevents severe damage under such circumstances.

The expanded closed cell cellular elastomeric material employed in the sheet inclosed within fabric envelope 11 may be produced in accordance with US. Pat. No. 2,570,182 or US. Pat. No. 2,788,333 or by other procedures known in the art for producing such impact absorbing materials.

Although the invention has been described in terms of an impact absorbent pad comprising a fabric envelope inclosing an expanded closed cell cellular elastomeric material, whichis the impact absorbent component of the pad, it is to be understood that other kinds of impact absorbent materials may be employed. The

type of material and thickness, density, resilience, tensile strength and other properties will determine how 7 effective the impact absorbent pad will be for protecting the neck and base of the skull of the wearer of the helmet shell. The important consideration is that the impact absorbing pad be sufficiently thick and be made of materials which will prevent transmission of enough force to the nape of the neck and the base of the skull through the rear. rim of the helmet shell or of the helmet to cause injury to the wearer of the helmet. The particular hazards to which the wearer will be exposed will determine in large measure the materials of construction and thickness required-in the impact absorbing pad, parachutists requiring greater impact protection in the area of the base of the skull than foot so]- diers, in general.

The impact absorbing pad of the invention is particularly useful in conjunction with conventional neckbands used with helmet shells, thus obviatingthe making of special neckbands for use by members of the Armed Forces who are likely to be exposed to such haposed against the nape area and the base of the skull of zards as the sudden and forceful jamming of a narrow rear rim or edge of a helmet shell or helmet against the nape and base of the skull areas in case of a fall involving striking the back of the helmet shell or helmet against a relatively unyielding surface.

The impact absorbing pad is most useful in combination with parachutists helmets, but it is not intended that its use should be so limited since it would be useful with any type of helmet or helmet shell which is made of hard or rigid materials. The impact absorbing pad has proven very effective in preventing serious injuries to the skulls and necks of a large number of parachutists who have worn such impact absorbing pads.

It will be understood that various changes in the details, materials and arrangements of parts, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art, within the principle and scope of the invention as expressed in the appended claims.
