An aviators crash helmet 1, suitable for the purposes of the'present inventiomis shownin Figs. 1 and 2. The helmet may beof the type disclosed in Patent No. 2,625,683, issued January 20, 1953.
The helmet 1- covers the head of the wearer and is open at' its-forward side to expose the'face. helmet include downwardly projecting ear-covering portions 2. The open under and forward sides of the helmet arebordered by a padded rim 3.
An eye shield 4 is movable into position to cover the eyes and upper portion of the users face. Arms 5 exate The sides of the tend from the eye'shiel'd 4 to p'ivotmountings 6 provided at opposite sides of the helmet. For the purposes of the present invention, the eye shield may be considered as conventional.
A guide track 7 extends forwardly and rearwardly along the crown of the helmet 1. A latch means having a latch handle 8 rides in the guide track and is connected to the eye shield 4 by a spring arm 9.
The retaining means constituting the present invention utilizes a conventional oxygenface mask 10 molded of rubber and having suitable passages, not shown, for communication with the mouth and nose of the wearer.
The face mask 10'includes cheek flaps 11 which cover the cheeks of the wearer. The face mask also includes a portion 12 which extends under the chin of the wearer. The forward portion of the face mask is directed downwardly to form a tubular snout 13 which is joined to a suitable supply tube 14.
The retaining means comprising the present invention includes a reinforcing saddle 15 having a nose-bridging portion 16 extending over the upper forward portion of the face mask and a chin web 17 extending under the chin portion 12 of the face mask.
The reinforcing saddle 15 is provided with a back opening i8 which permits the face mask 10 to project rearwardly therefrom and is provided with a front opening 19 through. which the tubular snout 13 of the face mask extends. The reinfor-cing saddle 15 is preferably formed of plastic material reinforced with glass cloth or other high strength material, or may be made of metal.
The reinforcing saddle 15 may be arranged to he slipped over the supply tube 14 into position on the face mask 10, and is contoured to conform closely to the irregularities of the. face mask. Alternatively, the reinforcing saddlemay be" molded integrally with the face mask, as indicated in Fig. 4. In either case, it is desirable that the reinforcingsaddle cover the valve elements, not shown, which are located within the face mask within the area embraced by the nose-bridging portion 16.
The reinforcing saddle 15 is connected to the helmet 1 by a harness structure 20. The harness structure includes a pair of chin straps 21 which extend downwardly from each side of the reinforcing saddle and cross under the chin web 17. The chin straps include extended portions 22 which are adapted to be directed toward the lower extremitiesof the ear-covering side portions 2 of the helmet 1. The harness 20 also includes a nose strap 23 which extends substantially horizontally around the nosebridging portion 16.
The nose strap 23 includes a pair of extended portions 24 which reach to the sides of the helmet 1 at levels above the chin-strap extended portions 22. The harness 20 is secured to the reinforcing saddle 15 by rivets 25, or other suitable securing means. The extended portions 22 of the chin straps 21- are preferably joined near their point of crossing by a cross strap 26, which underlies the chin of the user, preferably rearwardly of the rearward edge of the chin web 17 Each of the four extremities of the extended portions 22 and 24 is folded upon itself to form a loop which receives an eye 27 of a latch bolt 28. Each latch bolt is in the form of a flat metal strap having pairs of notches 29 along its lateral margins.
Each latch bolt 28 is adapted to be inserted in a latch keeper housing 30. Each latch keeper housing includes a base member 31, the under side of which is contoured to conform to the region of the helmet 1 in which the keeper housing is placed.
The base member 31 receives a top plate 32. Between the base member and the top plate there is defined a latch bolt guideway 33 and laterally directed latch lever slots 34. Suitable securingmeans 35 extend downwardly 2,852,812 Patented Jan. 13,1959
base member for securing each notches disposed along the corresponding margin of a latch bolt 28. The opposite ends of the latch levers 37 protrude to form handles 38. levers into engagement with the notches 29.
The notches 29 are so shaped that the latch bolts 28 may be readily pushed into their respective latch keeper Springs 39 urge the latch housings, but are normally restrained against removal by the pair of latch levers in each housing. In order to release a latch bolt 28, his necessary to engage simultaneously the handle ends 38 of the pair of latch levers 37. By reason of this construction the latch bolts may be readily released from the latch keeper housing when desired, but they are safe against accidental operation of either latch lever.
Operation of the retaining means is as follows:
;The reinforcing saddle and harness are fitted on the oxygen mask 10 as a permanent attachment, or as indicated in Fig. 4 the oxygen mask is mounted with the reinforcing saddle as an integral part. The helmet 1 is placed on the wearers head in the conventional manner and the oxygen mask is brought into place. The four latch bolts 28 are inserted in their respective latch keeper in} the event of an impending emergency the user may merely push on the respective latch bolts 28 to tighten the mask. To facilitate engagement with the latch bolts 28, small knobs or other projecting members may be provided adjacent the eyes 27 of the latch bolts.
The cross strap 26 which underlies the chin of the wearer is yieldable, and is normally Worn to permit some movement of the wearers jaw. However, it may be arranged to fit snugly when the straps are tightened, as inlthe event of an impending emergency. In the event ofimpact on the front of the mask 10 or its reinforcing saddle 15, cross strap 26, being of non-rigid material, does not constitute a danger to the wearers throat, as would be the case if the chin web 17 extended rearwardly to serve the anchoring function of cross strap 26.
Reference is now directed to Fig. 2. In the construction here illustrated, the chin strap extension 22 and corresponding nose strap extension 24 on each side of the mask 19 are joined to a common latch bolt 28a. Each latch bolt 28a is provided with a pair of spaced eyes 27a which receive the strap extensions. In the use of a single latch bolt for each sideof the retaining means, it is preferred to provide additional means for adjustment of the strap extensions. Thus the chin strap extensions 22 may be provided with adjustment buckles 41.
While the eye shield 4 has been referred to as con ventional, it should be observed that its lower margin is trimmed or shaped to conform to the upper portion of the reinforcing saddle 15.
Tests have been conducted utilizing the helmet, mask, and retaining means substantially as shown in Fig. l. A dummy was equipped with the helmet, mask, and reraining means and placed in an ejection seat on a rocket sled. The seat was ejected when the sled was traveling in excess of 600 knots at aMach number in excess of .9.
The mask and helmet remained in place and in functioning position on the dummy.
A helmet and mask held in place by conventional ,4 means have proven to be completely unsatisfactory under the conditions of bail-out at or'n'ear supersonic speeds. Loss of helmets during bail-outs and crash landings has left the head unprotected, with resulting severe and fatal injuries in most cases; 7
It should be observed that'the strap extensions 22 not only pull downwardly on the ear-enclosing portions of the helmet, but also by reason-of the chin strap '26 draw the ear-enclosing portions toward each other, so that these portions may press lightly'against the sides of the wearers head. I
The side-gripping action of'the ear-covering portions supplements the action of the face mask 10 and reinforcing means in retaining the helmet inplace, and distributes the load so that it is not taken entirely by the wearers chin. This -is accomplished by the aid of the chin strap 26 without causing the chin strap to press against the throat of the wearer.
While particular embodiments of this invention have been shown and described, it is not intended to limit the same to the exact details of the constructions set forth, and it embraces such changes, modifications, and equivalents of theparts and their formation and arrangement as comewithin the purview of the appended claims.
