Definitions

  • ABSTRACT An improved protective helmet for use by an infantryman or the like in which a suspension frame of relatively rigid material has a peripheral channel provided at one location around the frame with a slightly inwardly inclined portion adapted to receive a slightly outwardly directed portion of the edge of a rigid outer ballistic helmet body to permit the body to be swung to a position in which the entire edge thereof is received in the channel and in which position the body is securely held by a single fastener.
  • the frame is formed with a plurality of generally upwardly extending fingers which removably receive envelopes carrying pads of resilient material which adapt the frame to accommodate a range of head sizes.
  • a light line or cord is threaded through holes and slots around the frame releasably to secure both the crown assembly straps and the chin strap supports to the frame while maintaining the positions of the strap ends at predetermined locations around the frame.
  • the helmet body is formed of ballistic material sandwiched between rigid molded inner and outer shells.
  • the protective helmet assemblies of the prior art suffer from a number of disadvantages. Generally adjustment of the size of the suspension is difficult to accomplish. Most of the suspensions of the prior art accommodate only a very small range of head sizes. The helmets of the prior art are heavy. Suspensions of the prior art are permanently attached to the rigid shell with the result that the parts thereof are difficult to clean.
  • Our helmet minimizes the danger of injury from fasteners acting as secondary missiles. It prevents bottoming of the hard shell on the wearers head.
  • Our helmet accomodates a wide range of head sizes.
  • the suspension system of our helmet is readily removable from the rigid shell.
  • Our helmet is lightweight. It permits of the mass production at relatively low cost of a helmet having ballistic properties.
  • One object of our invention is to provide an improved protective helmet which overcomes the disadvantages of protective helmets of the prior art.
  • Another object of our invention is to provide an im proved protective helmet which minimizes the danger of injury from fasteners acting as secondary missiles.
  • Still another object of our invention is to provide an improved protective helmet in which bottoming of the hard outer shell on the wearer's head is inhibited.
  • a further object of our invention is to provide an improved protective helmet which accomodates a wide range of head sizes.
  • Yet another object of our invention is to provide an improved protective helmet construction which permits of the mass production at relatively low cost of a helmet having ballistic properties.
  • a further object of our invention is to provide an improved protective helmet having a suspension system which can readily be removed for cleaning or replacement.
  • a still further object of our invention is to provide an improved protective helmet which is lightweight.
  • an improved protective helmet including a suspension frame of relatively rigid material formed with a peripheral channel having a slightly inwardly directed portion at one location therearound. which portion is adapted to receive a slightly outwardly directed portion of the edge of a rigid protective helmet body to permit the body to be swung to a position at which its entire edge is received in the channel and in which position the body can be retained by use of a single fastener.
  • a cord threaded through holes and slots around the periphery of the frame releasably retains the crown structure and the chin strap supports to the frame.
  • a plurality of pouch-forming elements releasably carried by fingers extending upwardly from the frame receive pads which may vary in size to accommodate a range of head sizes.
  • FIG. I is a bottom plan view of our improved protective helmet.
  • FIG. 2 is a top plan view of our improved protective helmet with the outer helmet body removed.
  • FIG. 3 is a fragmentary sectional view of our improved protective helmet.
  • FIG. 4 is a side elevation illustrating the manner in which the body is assembled with the suspension frame in our improved protective helmet.
  • FIG. 5 is a side elevation of an alternate embodiment of our improved protective helmet.
  • FIG. 6 is a fragmentary sectional view illustrating the preferred form of helmet body incorporated in our improved protective helmet.
  • FIG. 7 is a side elevation of our improved protective helmet with the body removed illustrating an alternate form of crown structure which we may employ.
  • FIG. 8 is a plan view of yet another form of crown structure which we may employ.
  • FIG. 9 is a fragmentary sectional view of the crown structure illustrated in FIG. 8 taken along the line 9-9 of FIG. 8 and drawn on an enlarged scale.
  • FIG. 10 is a fragmentary sectional view illustrating one of the features of the crown structure shown in FIG. 8.
  • our improved protective helmet indicated generally by the reference character 10 includes a body 12 having superior ballistic properties.
  • the body I2 includes respective inner and outer shells 198 and 196 formed from a suitable material such, for example, as
  • a polycarbonate resin provided with a coating of a suitable clastomer which is applied to the shells either by compression molding or by a spray coat or dip coating method.
  • Sandwiched between the shells I96 and I98 is a layer 200 of ballistic material. While any high elongation, high tensile strength fibrous material having a high melting point may be employed. preferably we select one of the aromids which include aromatic polyimide resins develped by E. I. duPont de Nemours Company, and sold under the trademarks Kevlar and Nomex.
  • the fibrous material making up the center layer 200 may be woven, or it may be needlepoint felt, or it may be fibrous material loosely bound together by the use of any suitable binder.
  • our helmet includes a suspension frame 18 formed of any suitable synthetic resin.
  • This frame 18 has a peripheral channel 20, a portion 22 of which adjacent to the front of the frame is slightly inwardly directed.
  • the edge portion 16 is inserted in the channel portion 22 in the manner illustrated in FIG. 3, and the helmet body can then be swung down to a position at which the edge I4 is received in the channel around the entire periphery of the helmet.
  • the body 12 can securely be held in assembled relationship by use of a single fastener.
  • an upwardly-directed extension 24 at the back of the frame 18 carries a female fastener element 26 adapted to receive a male fastener element 28 secured to the hard outer shell.
  • each of the back and front of the frame 18 with a plurality of pairs of upwardly-directed extensions or fingers 30 and 32, 34 and 36, and 38 and 40.
  • Relatively wide gaps 42 and 44 separate the central group of fingers 34 and 36 from the outer groups of fingers 30 and 32 and 38 and 40 at the back and at the front of the frame I8.
  • the fingers 30, 32, 34, 36, 38, 40, 46, 48 and 50 all are molded integrally with the channel-forming portion 20 of the frame 18.
  • the upwardly directed fingers are thin and are thus somewhat resilient. Further, as will more fully be understood from the description hereinbelow, the fingers and the portion of the frame connecting the fingers to the channel 20 serve to hold the ballistic shell 12 in spaced relationship to the wearers head. Moreover, these parts of the frame I8 prevent bottoming of the helmet on the wearers head in response to a blow on the side of the outer shell. Thus the wearers head is protected against injury which might otherwise result from the hard outer shell being driven into engagement with his head.
  • Envelope 56 includes an inner skin 58 and an outer skin 60 which may be cut from a single piece of a suitable material such, for example. as glove leather, and stitched to form three compartments 62, 64 and 66. Each of the compartments 62, 64 and 66 carries an insert 68 of any suitable relatively soft material such. for example, as foamed natural or synthetic rubber.
  • the envelope 56 is assembled on the frame by slipping the outer skin 60 over the front fingers 30, 32, 34, 36, 38 and 40 so that each of the compartments 62, 64 and 66 receives one set of fingers and so that the edges of the compartmentforming portions of the envelope 56 are received in the spaces 42 and 40. This assembly operation further is carried out so that the insert pads 68 are disposed inside of the fingers.
  • our helmet includes a pair of side envelopes 76, each of which is made up of an inner skin 78 and an outer skin 80, which may be cut and stitched from a single piece of suitable material such as glove leather to form a compartment for receiving an insert 82 made of foam rubber or the like.
  • the outer skin 80 is slipped over the fingers 46, 48 and 50 so that the side edges of the envelope are received in the spaces 52 and 54 and so that the pad 82 is inside of the fingers.
  • a flap 84 on the outer skin 78 of the envelope 76 carries a plurality of spaced female snap fastener elements 86 adapted to engage male fastener elements 88 carried by the frame 18.
  • envelopes 56 and 76 may manually be applied to the frame 18 and may manually be removed therefrom. This operation permits of the insertion of pads 68 and 82 of different sizes, or of different numbers of pads, to accomodate a wide range of head sized.
  • removable feature of the envelope permits cleaning and replacement of worn parts.
  • Our protective helmet includes a crown structure, indicated generally by the reference character 90, which may be any one of a number of variations of a basic crown structure.
  • a crown structure 90 illustrated in FIGS. I to 4
  • a relatively closely-woven fabric is cut and stitched to form the peripheral portion 92 of the crown structure 90.
  • the crown strap 98 is stitched to the peripheral and central portions 90 and 92 so that it extends generally in a fore-and-aft direction over the wearer's head.
  • the other two crown straps 96 and are slightly curved so as to extend over the wearers head adjacent to the sides thereof.
  • Each of the crown straps 96, 98 and 100 has two free ends, each of which carries a length 104 of readily releasable attaching elements adapted to cooperate with a pad 102 of complementary elements secured to the strap at a location somewhat inboard of the free end.
  • One type of fastener which may be used is made by the American Velcro Company and sold under the trademark Velcro.
  • the length 102 may comprise a plurality of minute loops of synthetic resin adapted to be engaged by a plurality of minute books of synthetic resin carried by the pad or length 104.
  • the elements of the length 104 are engaged with the elements of length 102 to form a loop in the end of the crown strap.
