. In Italy May 4, 1939 Claims.

The present invention relates to improvements in life preserver equipment of the type involving voluminous water-resistant buoyant material enclosed in the manner of a cushion between two or more strips of water-proof fabric, the present equipment being designed for protecting persons not only against drowning but also against shocks, cold, and other dangers which occur during distress at sea and while swimming.

The life saving equipment according to the invention is characterised in that it employs approximately an X-shaped swimming vest which can be conformed closely to any adult body so as to eliminate any working of the device relative to the body, and wherein the buoyant padding is arranged to keep the head out of the water, whereby a stable and safe position of the body in' the water is assured, avoiding sidewise tipping in the water.

A further feature of the present life preserving device resides therein that two tying devices are provided which are attached to diagonally oppositely located points so that with every height of body there is always obtained a symmetrical distribution of the buoyancy of the device. The cushioned swimming vest is divided, in accordance with the invention, into three parts of which the middle part is preferably provided with horizontally extending sections, whilst the front and rear parts consist of vertical sections extending conically towards the waist, whilst in all three parts the centre sections are padded with buoyant material to the greatest extent, the lateral extremities of the parts having the least padding. The swimming vest may, if desired, be provided with more padding on the front than onthe back,

.whereby the body assumes in the water a vertical but slightly rearwardly inclined position so that the mouth will be located high above the water level.

The swimming device according to the'invention is adapted to be combined with diil'erent accessories varying according to difi'erent applications, such as a swimming helmet, a parachute, a breathing device, ballast weights, and/or a food container andthese combinations form also part of the invention.

A number of forms of construction of the invention are shown by way of example in the accompanying drawings, wherein:

Fig. 1 shows a simple form of construction of the device according to the invention with similar chest and back portions.

Fig. 2 shows a form of the device wherein the wherein the rear part is wider than the front part to provide portions to overlap around the sides and be tied l together in front of the wearer.

Fig. 3 shows a form of construction adapted especially for divers and the crew of submarine, and involving a breathing device and ballast weights Fig. 4 shows a separate form of construction for pilots who fly over the sea, and involving a parachute and securing straps. I

Fig. 5 shows one of the present devices folded and placed in a bag. a

Fig. 6 shows a form of buoyant material pad ded swimming and protecting helmet.

Fig. '7 showsanother form of buoyanthelmet having ear protecting means and breathing means;

Fig. 8 shows an auxiliary appliance comprising a bag for foodstuffs and a cover.

Fig. 9 shows how thedevice shown in Fig. 1 can be worn with the lateral extremities of the front part tied over those of the back part.

Fig. 10 shows the application of the said auxiliary appliance to a swimming device together with a helmet according to Fig. '7.

Fig. 11 shows the form of the invention shown in Fig. 3 supplemented by a simple helmet according to Fig, 6, showing the extremities of the back part tied in front rather than at the back of the wearer.

Fig. 12 shows how the device according to Fig. 4 can be worn with the extremities of theback part drawn around those of the chest portion,

together with crotch straps, and a swimming helmet according to Fig. 7. g

In the form of construction of the swimming vest shown in Fig. 1, in which the chest and back portions are similarly constructed, so that it is not possible for it tobe worn the wrong way round, I indicates the opening through which the head is passed when the device is placed on the wearer, 2 indicates the padded sections which cover the shoulders, chest and upper portions of the back. These sections, according to the invention have the greatest amount of padding, for the reasons set out above, and with the exception of the central area 2', the sections 2 extend parallel to the shoulders thereby facilitating ap plying the device by bending the same from the chest and over the shoulders onto the back. The sections at the lateral extremities of the. device are far lesscushioned, padding being reduoed in all directions outwardly. The separate sections 3 on the front and back parts are made slightly conical.

The numeral 4 indicates the securing bands which are sewn to the inner side of the conical sections or to their seams and which when tied in pairs around the body press the swimming vest firmly against the body. At 5 are indicated two rings for securing a food container on .the chest portion of the vest In the form of construction shown in Fig. 2 the sections 2" on the chest are more heavily padded with buoyant material than the sections 6 behind so that the swimming vest. has a pronounced front. The lateral extremities of the front are shorter than those on the back part, the latter being arranged to bear against the sides and front of the body. As mentioned above, an in clined position of the body in the water, due tothe greater mass of buoyant material in front achieved by th described arrangement, is thus obtained so that the. mouth of the wearer is at a high level.

The special construction for divers and for submarine crews, shown in Fig. 3, corresponds substantially with the form described with reference to-Fig.'2 but with the difference that. twov central sections 1 are provided which are filled with air or oxygen and are connected to each other by a tube 8 so that an equai quantity of gas is withdrawn from both sections 1' through the breathing tube 8' and the position of equilibrium remains undisturbed. The weights 9 are for the purpose of diving and for remaining some time under water, as also for enabling a slow rising in the water to be effected, without separate auxiliary appliances. When the device is used for submarine crews the weights can be detached separately one aftenthe other so as toenable slow and gradual rise through the water. Instead of the securing bands, belts [0 and buckles m are preferably used in this and other forms of construction. H indicates a mouthpiece with two short rubber tubules for the nostrils of the nose which permit of breathing under water through the mouth and nose.

The form of the device especially for aviator who fly over the sea, is provided in the back part I2 with a recess for a parachute which is secured in place by means of strong band's l3 and rings M, the device being otherwise free in the said strong bands t8 and I8", sewn to the interior of the swimming vest. The bands pass through the rings l4 and under the armpits of the aviator, whilst the ends {9' and Ill" pass crosswise through the crutch and are then connected together; The weight of the person thus acts substantially as a pull on the upper limbs. When the aviator has parachuted to the surfaceof the water, he

releases himself from the parachute by opening a spring catch hook which connects the parachute to the bandsystem f3. The arrangement of the padding is different in this example in that it extends throughout and the opposite sides thereof are connected together at spaced intervals.

The division of the swimming vest, according.

to the invention, into three main parts enables it to be folded together easily and tied by means of the extending bands and inserted conveniently into a bag 20 as shown in Fig.5.

The simple helmet shown in Fig, 6 has the featurethat because of the heavy padding of the rear sections 2, both at the head and neck parts of the helmet, remaining a long time in the water in a reclining position with the head raised out ofthe. water facilitated.

The helmet shown in Fig. '7 differs from that shown in Fig. 6 by the inclusion of check and ear protectors, and also by the provision of an air supply in the head part 22 of the helmet.

This air supply which is withdrawn through the tube 23 suffices for a few moments of submersion. However, the main purpose of the air container 22 is to withdraw breathing air from a level above the water level, the valve 24 serving to prevent water from entering the. container 2% and the mouth. 7

The food storage container 25 shown in Fig. 8 consists of a padded frame into. the recesses" of which there are fitted flasks 26 and boxes 21, beverages, medicines, signals and food. The button fasteners 5 are connected to the rings 5- of the vest. For'adapting the cushioning. of the swimming vest, which is thicker towards the neck, the parts 25' located in the vicinity 'ofthe waist are not only made: thicker than the'parts 25 located in the vicinity of the but the containers. are.- made to conform with the varying thickness, The. padding of the frame halances the additional weight. of the containers. A sleeve .28 with a slot 29,. capable. of being buttoned, prevents the containers from falling out of the frame 2.5; ft is itself secured to the frame 25 by buttons 39.

From Figs; 9 to 12, showing the device as worn, there is shown particularly clearly how the cross section of the sections increases conically, from the waist towards the. shoulders, Figs. 11. and '12 show how the ballast weights. are arranged for convenient detachment. and their equal distribu'- tion around the. waist zone.v

In its various combinations with a helmet, a parachute, a breathing device, ballast weights, and a food container, th life saving equipment according to the invention affords for the first timev a complete protection forthe various persons by whom it is worn under different circumstances when remaining in the water for a length of time.

The known arrangements, such as life belts and so forth are in no way suitable for being combined with these additional protecting and life saving appliances described herein. Further, only a construction of the swimming vest according to the invention enables the vest to firmly embrace and protect the upper part-of the body and ensure a Satisfactory location of the centre of gravity of the body in the water, while ensuring absolute freedomof movement of the limbs, and while combinedwith such additional articles of equipment.
