PARACHUTE Filed Dec. 5, 1934 s Sheets-Sheet s Patented "Aug. 25, 1936 3 Gabriel Tricau, Paris, France Application December 5, 1934, Serial No. 756,094 In Luxemburg December 8, 1933 9 Claims. (01. 244-21) This invention relates to parachutes, and it has particular relation to parachutes of the type which are enclosed, in period of non-utilization, in bags adapted to be carried by the users.

The bags of such parachutes were made heretofore in such a manner that, when they enclosed their sail and the shroud lines connecting the latter to the users, their thickness was too great and their weight was badly distributed on the user thus hindering his movements and causing him relatively great fatigue when he had to effect a definite work on board an aircraft whilst carrying his parachute. The sails of these parachutes once folded and enclosed in their bag could become packed, this being particularly prejudicious to their correct unfolding and sometimes causing accidents.

An object of the present invention is to remedy these inconveniences by providing bags for'parachutes, which bags present a large bearing sur face on the users body at the same time as a large surface for receiving their sail which 'is so folded and arranged that it cannot become packed and cannot entangle with the shroud lines which are coiled in a special compartment.

With these and other objects in view, which will become apparent as the description proceeds, the invention consists of the novel features of construction, combination of elements and arrangement of parts hereinafter described and pointed out in the claims.

For a better understanding of the invention, reference may now be had to the accompanying drawings forming a part of this disclosure, wherein:-

The bag for parachute illustrated in the ac- 5 companying drawings comprises a bottom face and a top face.

According to the invention, the bottom face I is formed by a surface 2 extending over the users back and comprising two

extensions

39 and 3d respectively extending over each of the shoulders vided, at the lower part, above the place correby small metal blades enclosed in sheaths formed by a lining sewn on the bottom face of the bag.

The bottom face I of the bag is inwardly prosponding to the users belt and transversely, with a strip 4, preferably resilient, which is sewn at its lower edge and at its side edges and thus forms a pocket opening at the upper part.

The bottom face I is also provided, on the one hand, at the lower part, at the users waist and on either side, with a band 5 terminating at its free end in a fastening means 6 permitting attachment to the buckle of the users belt'for instance and, on the other hand, at the end of each of the extensions 3g and 3d, with a band I also terminating at its free end in a fastening means 6, adjustable in length and also allowing to attach it to the users belt. The bands 5 and I each comprise a plurality of resilient strips 8 which impart a certain resiliency to the same, this allowing the bag of the parachute to perfectly fit the parachutist.

At the lower part of the bottom face I, below the strip 4, are secured reslient strips 9, transversely arranged and adapted to hold the shroud lines when the latter arecoiled.

.An opening is also provided at this place in the bottom face of the bag for allowing the passage of the shroud lines.

The top face of the bag constituted by a set of movable surfaces which are made integral with the bottom face I of the bag on its two lateral sides. This set of movable surfaces comprises, on the one hand,- two large flaps III which form the portion of the top face corresponding to the dorsal portion of the bag, these flaps It! being each secured, at one of their sides, to one of the lateral sides of the bottom face of the bag, and, on theother hand, four small flaps Hg and I Id which form the top portion corresponding to the two extensions of the bottom face of the bag, these flaps H being secured per pair, at one of their sides, to one of the lateral sides of the bottom face of the bag.

A turned down portion l2, secured to the lower edge of the bottom face of thebag, and turned down portions l3 secured to the inner edges of Y the extensions of the bottom face of the and 55 to the ends of these latter ensure the fluid-tightness of the bag when it is closed.

The flaps l0 and theflaps Hg and Hd, as well as the turned down portions l2 and H are provided, on the one hand, along their meeting edges and near the latter, with hooks I4 or with metal eyelets allowing to secure them together when closing the bag and, on the other hand, with resilient strips 15 transversely arranged and constantly tending to cause the said flaps I0, lg and lid and turned down portions l2, ii to fold outwardly upon opening the bag.

One of the flaps l lg and lid, preferably one of those which are arranged at each of the ends of the extensions 3g and 3d of the bag, are externally provided with a small pocket also constituted by four small flaps it for instance, the said pocket being adapted to contain the extracting parachute."

The flaps l5 are each provided, at their end, with a buckle I'l allowing to attach them together, by a rip cord, upon closing, and with resilient strips l8 transversely arranged for facilitating the opening.

The sail of the parachute, which is to be contained in a bag such as described above, is arranged in the latter in the following manner: It-

is first folded in spindle shape in the known manner, and this in such a way that after folding it has at its leading edge'a width equal to that of the bag which is to receive it. The leading edge of said sail is then placed in the pocket formed by the resilient strip 4; the shroud lines are taken out of this pocket and coiled in the lower part of the bag where they are held by the resilient strips 9, the loop formed by the shroud lines projecting outside the bag through the opening 30 provided in the bottom face of the latter and receiving the parachutists belt. The sail is then spread out, on the bottom face of the bag up to the end of one of the extensions of the bottom face of the latter, folded on itself and brought downwardly on the top of the pocket formed by the resilient strip 4, then folded again on itself and spread out up 'to the end of the other extension of the bottom face of the bag. then once again folded on itself and spread out circularly at the neck portion. The same series of operations, shown in the diagrams of Fig. 7, is then repeated until the entire sail has been housed in the bag.

The flaps iii are then connected together and to the turned down portion I! by lacing two laces l9 (Fig. 1) each constituted by a small sandow and one of the ends of which is secured to the turned down portion I! for instance, whereas the other end, which terminates in an end piece 20 provided with an eye is held stationary by a fastening cord 2| forming a loop.

The flaps Hg and lid are connected to the turned down portions l3 corresponding thereto and to the upper edge of each of the flaps I0 also.

by

laces

22g and 22d and 23g and 23d, one of the ends of all these laces being secured to the said flaps or to the said turned down portions, whilst their other end also terminates in an end piece provided with an eye in which the fastening cord 2| passes.

Thus, the'same fastening cord holds all the end pieces of the laces. Two fastening cords might be employed, one of which would be left rather loose in order to avoid untimely opening.

It is to be noted that, upon lacing, said laces are tightly stretched so as to come out of the hooks l4 when the cord 2| is broken.

The extracting parachu is enclosed in the pocket formed by the flaps IS, the latter being subsequently connected together by a cord 24 These two cables might obviously directly control the cutters 25 adapted to cut the cord 2!.

When a pull is exerted on either of these two cables, the cord 24 is broken and the pocket formed by the flaps 16 opens: the extracting parachute is released.

The latter is caught by the wind, unfolds and causes all the cutters 25 to act for cutting the cord 2|. The laces I9, 22g and 22d and 23g and 23d, owing to their resiliency, retract and release the flaps, this causing the bag to open and allowing the sail to be released and to unfold.

It is to be understood that the cutters 25 can be actuated by the two cables having an automatic and controlled action and also by the small extracting parachute, these three means for cutting the fastening cord can be assembled together or separately.

This bag therefore presents a very large surface bearing on the user's bodyand ensures a. suitable distribution of the weight of the unit: bag, sail, shroudlines, etc. Moreover it has a very small thickness and does not cause any discomfort, whilst ensuring a certain'and positive opening at the time the parachute is used.

As the bands 5 and the bands I are connected by their ends to the buckle of the belt of the parachutist, the latter, upon landing, discards the whole in the usual manner by acting on the buckle of his belt.
