Abstract
ABSTRACT OF THE DISCLOSURE
A garment to be worn conveniently and comfortably over the upper body of a seagoing person to gain protection from rain, wind, and/or cold, which includes an interior deflated fluid tight enclosure, i.e. a bladder, to be very quickly inflated inside the garment in a time of emergency. The deflated fluid tight enclosure covers at least the interior upper back portion of this garment and also covers at least the interior of the right and left chest portions of this garment. An inflating subassembly is operatively secured between the deflated fluid tight enclosure and to either the right or left chest portion of this garment. This inflating subassembly has an alternatively usable month and lung inflatable valved air intake-discharge communicating with the deflated fluid tight enclosure, and an alternatively usable filled compressed fluid valved cylinder discharge also communicating with the deflated fluid tight enclosure and having a coilable pullable lanyard. Then a pocket like subassembly is removably secured, by using loop and hook fasteners on the exterior of the garment at either the right or left chest portion and is non removably secured to the coilable pullable lanyard. This pocket like assembly fully covers and protects the inflating subassembly, until an emergency, when the seagoing person intentionally, readily, and quickly, pulls the pocket like assembly away from the garment, causing the pulling of the lanyard to activate the valve on the compressed fluid valved cylinder. The fluid tight enclosure is then quickly inflated, creating the buoyancy needed by this seagoing person.

BACKGRO~N~ OF THE INVENTION
Field of Invention The invention pertains to the art of inflatables, and more particularly to the art of manufacture of inflatable life preservers, especially those adapted to be integrated in a vest or jacket like protective garment. The invention thus falls within the field of inflatable life preservers, which are an integral part of a garment designed for a use other than li~esaving. The invention, further, is so designed as to be adaptable for military and civilian use, installed in an oilskin jacket.
Prior Art Most inflatable personal flotation devices in use today are a separate unit requiring extra time and a conscious awareness of a dangerous situation for use. The inflatable personal flotation devices that currently are integrated into garments are primarily designed for use by the military, intended forspecific applications, or for the yachtsman who occasionally is exposed to a potentially dangerous situation. In that regard many professional mariners, especially commercial fishermen, are frequently reluctant to be seen, or to be bothered, wearing a personal flotation device even when conditions are dangerous.
Typical of the prior art as described above are the following 129~
patenks:
J. Harding, et al. 3345657 H, J. Moran, et al. 3771183 C. E. Erickson 2823396 It has been important, in inflatable personal flotation devices as those shown in the prior art patents, to assure that the flotation compartment design be capable of incorporation with various types of military and sportsmen garments and that the flotation compartment offer ample buoyancy so as to keep the head of the wearer out of the water. The prior art patent of R. J. Moran even offers an additional flotation compartment as a safety factor; that is, if one of the two flotation compartments is damaged the other will adequately support the wearer. The prior art inflatable personal flotation devices have unquestionably been of great benefit to those who had need and were equipped with one of these devices.
~ owever, certain deficiencies must be noted in the prior art. In the prior art inflatable personal flotation devices cited above, these inflatables are designed to be worn separately and/or incorporated into a specific type garment. It is not reasonable to expect a professional mariner to wear a military flight suit or a sportsman vest while at sea. It is also impossible for an inflatable personal flotation device to save a life if it is not on the person or available to them at their critical time of need. The majority of deaths caused by man overboard lZ96951 accidents are not the result of a predictable situation or an inherently dangerous one; most often it is the result of a freak accident in which the unfortunate victim is pitched into the sea. According to the U. S. Coast Guard a full 75 per cent of these victims might have lived had they been wearing their personal flotation devices. It must also be noted that the large majority of mariners are not in the military and therefore do not have access to those inflatable life preservers of the prior art should they have the inclination to wear them. Although many commercially available life preservation devices have been approved by the U. S. Coast Guard, for use by the general public, for the most part these devices remain in a locker somewhere ready for use should the occasion arise. There are other products currently available that perform this function far better than an inflatable personal flotation device; for example the survival suit is designed to not only keep a victim afloat but also to protect against exposure and hypothermia. If a victim were aware of impending danger, i.e. the boat is sinking, or the weather is more severe than the boat is capable of withstanding, the victim would no doubt use the survival suit rather than the currently available personal flotation devicesf both of which are probably in the same locker. It is therefore of primary importance that a personal flotation device become standard equipment of those who work at sea. This is best accomplished by integration of the inflatable flotation compartment with lZ96951 a garment that is already standard equipment for those who work at sea.
The present invention is intended tocorrect these deficiencies in the prior art, by integrating the inflatable flotation chamber witb the most common and most utilized piece of personal gear used by all those who venture upon the sea, most especially commercial fishermen and others who make their living upon the sea.
SUMMARY OF TEE INVENTION
The subject invention is an inflatable buoyancy oilskin jacke~ further comprising a lifesaving inflatable buoyancy garment accessory which is adapted for removable or alternatively permanent attachment to the inside of any oilskin foulweather jacket worn by fishermen in particular. The inflatable buoyancy jacket invention is normally worn in the deflated mode by the fishermen as they work on board the ships and may be inflated manually or in an alternative embodiment, automatically should the fisherman be swept overboard for example. The invention broadly comprises a U-shaped continuous inflatable chamber which is secured to the inside of any oilskin foulweather jacket. Inflating means include an inflator assembly as well as an auxiliary oral inflator tube. The U-shaped chamber is adapted such that a collar section is secured to the upper back portion of the interior of the 125~i9~1 oilskin jacket while body lobes extend down each side of the jacket to lie upon the chest of the wearer. The inflator assembly has an attached lanyard which is in turn secured to a pocket flap cover removably mounted on the front of the oilskin jacket.
Activation of the inflator assembly is accomplished by removing and then pulling down on the pocket flap cover. The cover is secured to a lanyard which is secured at its opposite end to a lever. A C02 cartridge, secured into an extending portion of the chamber, is then activated to inflate the chamber by being punctured by a spring activated piercing pin connected to the lever.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the various drawings, it will be noted that the preferred embodiment of the inflatable buoyancy jacket 10 or jacket 10 broadly comprises: a standard oilskin, a U-shaped continuous inflatable flotation chamber 12 and an inflator assembly 20.
As shown in figure 1 of the drawings, the inflatable buoyancy jacket 10 is ~o be worn primarily by fishermen in the deflated mode while working on board their fishing boa~s. The inflatable buoyancy jacket 10 may be worn in combination with overalls or waterproof pants together to serve as foulweather gear and protect the fisherman against rain as well as the waves and water which spills from the fishing nets as they are hauled in. The oilskin is a standard item and may serve as the basic garment for which the inflatable buoyancy jacket 10 invention is made.
The U-shaped continuous inflatable chamber 12 or chamber 12 further comprises a collar section 14 and two body lobes 16. The chamber 12 is secured at its collar section 14 along the upper interior of the jacket 10 at the upper back portion 18 as shown in figure 4. The body lobes 16 continuously communicate with the collar section 14 to form a single cavity within the chamber 12. The body lobes 16 are secured to the interior of the iacket 10 along each side as shown in figures ~ and 5.
Points of connection spaced along the perimeter of the chamber 12 are referred to as 40, as illustrated in figures 3, 4 and 5. Such attachments may be made with stitches, snaps, rivets or any other method which will firmly locate and secure the chamber 12 in the jacke~ 10. While the primary embodiment of the invention incorporates a permanently secured chamber such as with stitches, other embodiments may include a detachable or interchangeable chamber which may be sold as a separate accessory and installed in the fisherman's previously purchased jacket.
The chamber 12 is preferably constructed of a lightweight polyurethane coated nylon, neoprene coated nylon, rubber, vinyl or other lightweight gas retaining material.
The inflator assembly 20 is secured to the exterior of the jacket 10 to extend into the chamber 12 and permit the trans-mission of air to fill the chamber 12.
The inflator assembly 20 utilizes a sealed CO2 cartridge 22. Details of the inflator assembly 20 are limited for the sake of simplicity since its components are often used on life ~L~9~
preservers and the like. The assembly further includes a lever 24 which is connected at one end to a spring actuated piercing pin 26. The lever has a lanyard 28 attached to its opposite end as shown in figure 7. The opposite end of the lanyard 28 is secured to the interior of the pocket flap cover 30. When the pocket flap cover 30 is pulled away from its velcro mounting strip 32 and then pulled downwardly, the lever 24 is consequently pulled downwardly, thereby activating the piercing pin 26 which then punctures ~he CO2 cartridge 22 causing inflation of the chamber 12 upon demand. The sealed CO2 cartridge 22 is removably mounted into the threaded end of the transmission portion 27 of the inflator assembly 20.
The primary embodiment of the invention re~uires the fisherman or other wearer to manually remove the pocket flap cover 30 to activate the inflator assembly 20; an alternative embodiment would provide for automatic inflation when the inflator assembly 20 was submerged in water. In such embodiment, the spring activated piercing pin 26 could be held in an inactive position by a salt grain or tablet of other dissolvable material which would activate the piercing pin 26 upon being dissolved in the water. Other possible means could be used for automatic inflation as well.
An auxiliary inflating means is provided by the oral inflator tube 34 as shown in figure 6. The oral inflator tube 34 may be used if the inflator assembly 20 fails to operate. The oral inflator tube 34 will normally be screwed in place to seat against S~
the surface of the jacket 10 to serve as a valve. Deflation of the chamber 12 may then be accomplished by unscrewing the tube 34 such as is done with other lifesaving vests.
A pocket flap cover 30 is removably secured to the front of the oilskin jacket 10 preferably at breast pocket location.
The pocket flap cover 30 or cover 30 is preferably secured to mounting strips of velcro 32 which have been attached to the front of the oilskin jacket 10. Snaps or other means may be used to secure ~he cover 30 in place, to serve as protection for the inflator assembly 20 and oral inflator tube 34 which project from the chamber 12 through the jacket 10 to be accessible beneath the cover 30. The cover 30 also serves to prevent damage or interference to the inflating means from exterior sources, yet allows for manual activation with a gloved groping hand.
The pocket flap cover 30 is additionally secured to the jacket 10 by a top flap 36 which is stitched or otherwise permanently affixed to the oilskin jacket and across the ~op and down the sides of the top flap 36 as illustrated in figure 6.
An additional feature of the inflatable buoyancy jacket 10 is a safety buckle 38 which is secured to the bottom of the coat and may be wrapped around the midsection of the wearer to prevent the jacket 10 from coming off in case it is unsnapped while the wearer is in the water for example.
