MAN-CARRYING PARACHUTE HARNESS Filed Dec. 17, 1948 2 Sheets-Sheet 2 Patented Aug. 22, 1950 UNITED STATES PATENT OFFICE (Granted under the act of March 3, 1883, a amended April 30, 1928; 370 O. .G'. 757) Claims.

The invention described herein may be manufactured and used by or for the United States Government for governmental purposes without payment to me of any royalty thereon.

This invention relates to parachute apparatus and more particularly to parachute harness for aviators having for an object the provision of an improved harness which is lighter in weight, less concentrated in bulk, quickly and fully adjustable to size, simple to fabricate or manufacture, and also more comfortable to Wear, and convenient to put on, adjust or take off.

Another object of my invention is the provision of a parachute harness having adjustable body encircling means for supporting the stomach, hips, and back of the wearer, including strong, comfortable load sustaining means extending around the seat, thighs, and body of the wearer to more effectively encircle and effectively and more comfortably support the body during opening shock and descent of a parachute when attached to the harness, incorporating quick detachable fastener means for releasing the load sustaining websof the-attached parachute from the harness, and quickly and conveniently releasing the body encircling and confining strap features of the harness at a minimum number of separable connections, so that the wearer can quickly and efficiently divest himself of the harness.

A further object is the provision of a personnel parachute harness having a main seat sling; member with a pair of leg or thigh encircling strap elements superimposed and secured thereon, including loop means on the sling member slidably connecting the leg encircling strap elements to the main sling member at opposite sides of the wearers body, in which the leg strap elements then extend forwardly towards each other to provide supporting means across the wearers stomach, the loop means includes flexible rearwardly extended looped portions, and shoulder and back strap elements extending upwardly from the seat sling member, then rearwardly and downwardly across each other at the back of the wearer and looped through the flexible looped portions towards each other and adjustably connected together to provide supporting means across the small of the wearers back substantially in the rear of the detachably connected ends of the leg or thigh encircling strap elements.

A further object is the provision of separable breast strap connecting means connecting the upper ends of the main sling strapmember together across the wearerschest,substantially in front of thecrossed portions of the shoulder and back strap elements.

A still further objectis the provision of adjusting means intermediate-the ends of-the main sling member, and in the leg or thigh encircling strapelements for adjusting the harness to the size and shapeof the wearers-body.

A further object is the provision of a single detachable connection for securing the shoulder and back strap elements and main-sling member together across the chest of the wearer, and a second single detachable connection for securing the looped endportions of theleg or thigh encircling strap elements together across the stomach of the wearer, including adjustment means in the main sling member, and inthe leg. strap elements for quickly adjusting the harness to fit the-body of the wearer.

A still further object isthe provision of improved flexible loop retainer means projecting from the opposite edges of the main sling member substantially across the hips of the wearer, receiving the looped ends of the shoulder strap elements therethrough, rearwardly of themain sling member, and receiving the looped end portions of the leg strap elementstherethrough forwardly of the mainslingmembers.

Other'objects and advantages ofmyinvention will become apparent from the following description, taken in connection withthe accompanying drawings, in which like reference characters refer to like parts in the severalfigures.

Fig. 1 is a side elevation of my improved parachute harness illustrating the same inposition on an aviator. The load suspension or lift webbing of the parachute being shown in operative position in phantom.

Fig. 2 is anenlarged perspective view of my improved harness, illustrating the same applied to a conventional parachute pack of the-back" type, with one ofthe parachute loadsuspension or lift webbing disconnected from the harness, and with the chest strap fasteners disconnected.

Fig. 3-is an enlar-ged fragmentary detail plan view of a portion of one sideor reach of the-main sling or seat strap member, more clearly illustrating the construction of the flexible loop re tainer members and reinforcing webs therefor which extend from the opposite edges of the main'sling members to slida'bly receive andretain the looped portions ofthe-leg and shoulder while the numeral 2 indicates a parachute pack of conventional design, known generally as a back pack, having a pair of lift webs or load sustaining straps 3 which extend into the pack and are connected to the shroud lines of the packed parachute that is releasably contained in the pack 2. The parachute contained in the pack 2 comprises a canopy, not shown, having shroud lines, not shown, which converge downwardly from the periphery of the canopy when in descent, preferably in two groups with the load suspension webbing or

straps

3, 3 each connected at their upper ends to one of the groups of shroud lines.

The lower ends of the

lift webbings

3, 3 are each detachably connected to a shackle 4 secured on the harness l in the conventional manner so that release manipulation of the shackle or fitting 4 quickly frees the parachute load sustaining webbing or

straps

3, 3 from the harness in the conventional manner, thus disconnecting the chute from the harness.

My improved parachute harness I includes a main flexible sling member or strap 5, having its upper ends spaced apart and connected to the lower bars 6 of the shackles 4, and depending downwardly and somewhat rearwardly from the shackle 4 as seen in Fig. 1 to form a seat sling portion 1 for the wearer to sit on. The main sling or seat member 5 extends through the fittings 4, is looped back on itself to provide return loop portions 8 which are adjustable in adjustable fittings or buckles 9 carried on short flexible looped straps I secured to the main seat sling member I, preferably at the upper ends of a pair of leg or hip encircling strap elements II. This arrangement permits adjustment of the effective length of the main sling member 5, or rather for adjusting the length of the two upstanding ends of the main sling member as indicated at 8 in Fig. 1, to position the detachable fittings or shackles 4 substantially in front of the wearers shoulders and chest.

The main sling member and the encircling leg straps or hip loop members II extend downwardly from the buckles 9 in superimposed relation to each other with the leg straps I I on top of the sling member 5 as shown in Fig. 2, the leg straps II being looped around the main sling member 5 at or adjacent a position under the crotch of the wearer as indicated at l2, I2, then extend forwardly and towards each other as at I3, to provide a pair of leg or hip encircling strap elements [4, as seen in Figs. 1 and 2. The superimposed strap portions 5, I, and II located between the looped over portions I2 and the buckles 9 are securely fastened together and reinforced by stitching throughout this distance, the looped over portions I2, I2 being flattened down on the main sling and securely stitched in place as shown. The ends of the looped portions I0 carrying the buckles 9 are interposed between the webbings I and II, just below the buckles 9 and securely fastened by stitching or other suitable fastening means.

Just below the looped strap portion I0 carrying the

buckles

9, 9 is a flexible retainer loop portion composed of flat strongly woven webbing indicated generally at I5, I5, the ends of the web straps I5 being securely anchored between the seat sling member 1 and the respective leg strap members II by stitching, indicated at I8 and I9, the intermediate portion extending between the leg and seat strap members and securely fastened thereto at 20. This arrangement provides the main sling member I with two pairs of flexible loop retainer members 2i, 22, loop member 22 extending forwardly from the front edge of the superimposed seat and leg strap elements, the free or forwardly extending leg strap portions I4, I4 extending upwardly and looped through the retainer loop members 22, as seen in Fig. 2. The two leg strap elements are then brought forwardly and toward each other to form a connected cross strap or web portion Ma disposed when tightened to extend across and support the body of the wearer, substantially across the stomach. The ends I la of the leg loop strap members I4 are looped through the bar members of a pair of adjustable separable fasteners 23 and 24. The fastener 23 has an eye portion 23a to receive the snap hook extremity of the fastener 24. The free ends of the leg strap portions Ida are folded and stitched to provide abutment pads Mb to prevent the IDOItlOl'l looped through the bar members of the separable fasteners of buckles from being displaced or withdrawn, and to provide pull means whereby the wearer can easily slide the looped ends to tighten the leg and hip loops I4 around the legs or hips of the wearer as seen in Figs. 1 and 2.

It should be noted that the retainer loop webbing or members I5 are reinforced by narrower strips of strong flexible ribbons as shown in Fig. 3 at 25, being securely stitched along the seat and leg webbing portions I and I I as indicated at 26, with their ends extending toward each other at 21. The ends may be overlapped if desired to afford maximum strength. The portions of the reinforcing webbing 25 are narrower than the width of the looped portions 2I and 22 and are secured thereto to permit the looped retainer webbing to roll, providing loops which are rounded in cross section at the inner sides of the loops where the leg straps pass through and engage them, and where the shoulder straps, later to be described, pass through and engage.

The upper bars 28 of the fittings 4 each have the loop extremity of one of a pair of shoulder and back strap members 2 9 and 36 secured thereto as best seen in Fig. 2. These shoulder straps 29 and 30 are arranged to extend over the shoulders of the wearer and then downwardly and across each other as indicated at 29a and 30a, and are then looped through the upper loop retainer webbing 2| and extend towards each other across the back of the wearer as indicated at 29b and 39b, their extremities being looped through and quickly adjustable in the buckle fittings 3| and 32, secured to the opposite ends of a connecting back strap 33, adapted to be positioned across the small of the wearers back, substantially in the rear of the stomach strap portions I 4a of the leg straps I4.

The parachute pack, as shown in Fig. 2, and as before mentioned, is conventional and one of many types that can be worn with or attached to the harness by the lift webbing or

load sustaining straps

3, 3 of the parachute proper, by detachable connectors or shackles 34 which are separable from the main fittings or anchors 4 in the usual manner, such as by pulling the release cords 35, also conventional in construction and operation. The parachute pack 2, as shown, is a back type pack of the static type, preferably using a static line for opening the pack to free the chute, rather than the usual pull or rip cord, and in order to more securely support the pack on a harness the pack is provided with stitched webbing or loops 33p and 30p for the back connecting straps 33 l and the crosse'd back straps 29a and '30a to pass respectively freely therethrough. Also an intermediate strap 29p, stitched at its upper and lower ends is located adjacent'the top of the pack and accommodates the crossed portions of thestraps 29aand30a. Other and different attaching -means may be provided on the pack if desiredsince theyform no part of the invention as claimed,other:-than means 'for securing the pack tothe harness.

A separable breast or chest strap is provided, indicated-generally at36, and designed when-connected together to lie across the chest or breast of the wearer substantially in front of the crossed portions 29a and 30a ofthe shoulder andiib'ack straps 29 and 36. The chest strap 36 has a 'quick detachable shackle or separable-fastener Tr-interposed in its length,consis.ting ofaconventional eye 31a and snap hook element 31b. The portions 31a and 3772 as shown,infact, each include a short strap with each end looped over the other .end to provide a slide loop extending around one of the adjustable end portions -8-of the main sling member 5, and to receive one of the anchor-bars of the said snap hook oreye elements of the separable fastener 31.

" My improved harness is preferably woven of strong flexible webbing or'strap material such as nylon and stitched with thread of thesame material, thus'I am able'to-fabricate an extremelystrong and durable parachute harness having aminimum amount of weight and bulk. It should be noted that only two separable fasteners :of the-quick detachable type are provided in order to release and remove the harness from the wearer. The disconnection of the chest strap fasteners 31a and 37b frees the shoulder and upper body encircling straps 29 and 30 so that the wearer can remove his arms from the harness, while the release of the snap fastener 24a, frees thelegstraps l4 and the looped front or stomach band portion Ma, permitting the leg strap members Mato slide in the flexible retainer'loops 22, to.enlarge the leg or hip encircling loops so that the legs of the wearer-can. easily-be removed from theharness, further slackening of the straps 1.4, Ma can be accomplished by slipping the portions .Ma in the buckles .or anchor bar members of the separable fastener 23, 24.

-In.order to don the harness thewearer needs only to place the straps .29 and 30 over theshoulders while sitting on the seat sling I, connect. the chest strap fastener 31a, 31b, pass the two leg straps through between the legs and upwardly through the retainer loops 22 and towards each other across the stomach, fastening the quick detachable fastener 23, 24 together, and then'pull the ends Mb and Nb to tighten the leg straps.

Adjustment of the harness to fit nearlyany shape andsize wearer is also easily accomplished. Adjustment of the lower (free) ends of the cross straps 36b, 25a, will adjust the length of the shoulder and crossed back straps, and since the straps 2-9 and 3t slide easily in the retainer loops 2L2! on the main sling member ,1, this adjustment also adjusts the degree of slack or tension in the lower or horizontal back supportingband 33. Adjustment of the leg straps has already been explained. In order to provide adjustment for the height of the wearer the upper portion of the main sling or looped extremity 8 is easily adjustable, which provides the adjustment and proper positioning of the shackle connectors .4 for the parachute lift webbing in front of and below' the shoulders of the wearer, and also affords additional ;:adjustment :for lthe "length and asize of Fthe shou-ldersloopsl and theiproper positioning of theicrossstraps I;4a,.-l.4aat the backof the wearer.

the'type of packz2, .as shown-.somewhatzdiae grammatically in the drawings the parachute proper is'securelyinclosed in the pack .withithe two lift webbing elements or load sustaining straps 3-from. the chute extending out. of thelopposite cornersofthe. pack, as shownin Fig.2 with their ends 34. releasably connected to the fittings 4. When the pack is worn these-straps lie across vthesshoulders of the wearer above the shoulder straps 29 andx3ll, somewhat as illustrated inthe disclosureiin Fig 1, and when the parachute'is releasedandis in descent the two lift webs then support'the wearer directly from thefittings A connected to the upper ends of the main seat sling has shown; in phantom in- Fig. 1.

My improved harness effectively encircles and supports:the.wearers chest and back, waist and hips,-and:thesmall of the'back and thestomach, making the body supporting functions of the harness extremely effective and more comfortable during opening shock and descent. The looped portion 2| and 22 surrounding and supporting the opposite sides-of the body at and above the hips without excessive overlapping orbulk of the strap members, making theharness more comfortable to wear, especially in small or cramped quarters in military fighter aircraft.
