Inflatable life jacket

The invention relates to an inflatable life jacket or similar inflatable personal rescue device with special, but not exclusive reference to such life jackets, which consist of two elongated, inflatable There are parts that can be placed side by side on the wearer's chest, while a third is inflatable Part permanently connects the adjacent ends of the two first-mentioned parts and goes around the neck at the sides and back of the wearer, with means for securing the life jacket to the wearer's body being provided.

Life jackets of this type of "split stole" which are either fitted with fastening straps or built into an item of clothing (e.g. a vest or Jacket) ι are standard equipment of the crew and other persons, for whom the possibility of a parachute jump consists of an airplane.

It is known to provide the fastening parts of a life jacket with a storage pocket or with tabs, in or under which the inflatable parts can be housed in a space-saving rolled or folded form, so that they are when Subsequent use of the parachute harnesses do not interfere with the latter or fail to fully deploy in the event of their Self-inflation will be prevented when the wearer is still is in the air.

If seat belts also have to be worn, it is common for the life jacket to be put on over the parachute belts Attachment and adjustment to the body must be completed before the jacket can be closed, an operation that is right is complicated when the belts over a "partial pressure suit" whose chest area is equipped with a generic regulator for the oxygen supply «

The invention is based on the above findings and sees its task in facilitating and accelerating the application a life jacket of the type mentioned and the associated parachute equipment.

009820/0013

The solution according to the invention consists in a life jacket of this Kind, on the inside of which parachute belts are detachably attached, in that the life jacket and the parachute belts have a common fastening device that also controls the setting parachute harnesses allowed *

Advantageously, the fastening device comprises two metal plates attached to opposite edges of the holding devices for the life jacket and the parachute straps are attached and each of which at the edge spaced formations possesses, with corresponding, similarly spaced formations on the other plate by combined Meshing and relative longitudinal displacement can be brought into engagement with one another

Further details of the invention emerge from the following Description of the exemplary embodiment shown in the drawing «It is:

Fig. 3 is a perspective view on an enlarged scale. which shows the attachment of a fastener to the life jacket and its interaction with the parachute straps]

Fig. 4 is a partial front view of the fastening device: in the released state and

Fig. 5 is a larger-scale section along line V-V of Fig. 4.

In the example shown, the invention is applied to a life jacket constructed in the manner of the subject matter of British patent specification 1,046,696 in which the retaining parts consist of a vest 10 with a central front opening 11.

Tabs 12, 13 «14 held by push buttons or pressure bolts on the inside of the front and rear part of this vest releasably secure the parts lying in the corresponding places the parachute harnesses 15 known type

The main strap of it consists of two parts 16, 17 attached to their Ends are connected by quick release locks 18. It is arranged in a figure of eight, with its smaller loop and the Crossover is formed by the part l6 and is held on the back of the vest 10 by five tabs 12, while the larger loop formed by the part 17 around the arm holes 19 and through tabs I3 on the front part of the vest such is guided that it leads around behind the thighs of the wearer.

Two adjustment straps 20 pass from the center of the strap portion between the legs of the wearer and through lower and lower upper slots 21, 22 in each half of the latter and are adjustable on the fastening parts 23 acting together or 24 of the vest opening 11 attached. Between the corresponding Points of intersection with the belt part 17 guide these belts 20

009820/0013

under pairs of flaps 14 on the inside of the vest 10 through as well as by interposed slotted metal sliders 25 on the belt part 16.

It should be noted that the ends of the belt parts 16, 17 are guided in a corresponding manner through slots 26, 27 in front of the armholes 19, which separates the belts 15 from the vest 10 facilitated while wearing the vest as the connecting locks 18 are external to it · each of the above mentioned fastening members comprises an elongated plate of stainless steel or similar metal, which in the case of the member a series of spaced apart lobes or projections 28 on their free edge, which have a keyhole cross-section} while the corresponding edge of the Link 24 shows complementary edge thickenings 29 which are somewhat shorter than the spaces between the projections 28.

It can be seen that by relative longitudinal displacement of the members 23, 24 · after their associated edge formations have been pushed into one another, a firm connection is achieved, the projection 28 at the end preferably being "blind" by an obstacle, such as that shown at 30, so that the Coupling of the fastening members can only take place by displacement in a longitudinal direction, suitable devices, for example a spring-loaded stop 31 '' being provided ^on the member 23 between two projections 28 to prevent unintentional

To prevent detachment of the thickened edges 29 from the projections 28

Instead of the edge formations described, both members 231 each may be provided with rows of hook-shaped projections, one set of projections reversed from the other is arranged and is slightly narrower to allow the required interlocking

Each of the links 23t 24 is widened at one end and with

equipped with a longitudinal slot 32 which has a round rod 33 has that is slidable across its width and around the the associated adjustment strap 20 of the parachute straps 15 in the in the manner shown in Fig. 3 before going through the slot got on the outside of the vest 10 "

Strips of fabric 35 on opposite edges of the vest opening are passed through further longitudinal slits 36 in the links 23 »24 and sewn in, so that the mere securing of the vest 10 the parachute straps 15 are also attached to the body at the same time, which can then be adjusted by pulling outwards on the free ends of the two straps 20 on the outside

When the combined life jacket and parachute harness (which can wear a snow release device 37 for connection to the seat belts and parachute accessories) over one Partial pressure suit or doublet can be worn, a regulator (not shown) for the oxygen supply to the inflatable Parts of the latter be attached to one of the fastening members (for example by releasable fastening to the

Keyhole slots 38 in link 23 are used for this purpose is made relatively broad), its presence on this link the connection or disconnection of the links 23, 24 in no way affected.

The lower corner of each mounting plate can if necessary cut away to enable the connection of the oxygen supply with the partial pressure suit
