Definitions

  • the present invention relates to a life vest.
  • the life vest finds particular application for use by pilots, crew and passengers of helicopters, but such use is not limiting on the scope of the invention.
  • Helicopters are often employed in over-water flight. In a country such as Australia the coastlines are a tourist attraction and the use of helicopters allows tourist to see the vast areas quickly and easily from the air. Another use for helicopters is for off-shore oil rigs, where they are utilised to transport staff to and from offshore installations. Helicopters can have large passenger capacity, and can carry as many as twenty passengers. The military is another example of where helicopters are provided as transportation means.
  • ditching When a helicopter is crash landed into the water it is called ditching. Ditching can be caused by loss of engine power, mechanical failure of critical components, excessive vibrations, poor weather conditions or pilot error.
  • the present invention provides a life vest, including:
  • a pocket on the body or other component of the life vest containing a personal respirator tank and attached mouthpiece;
  • the invention provides a life vest kit, including:
  • a personal respirator tank and attached mouthpiece a pocket on the body or other component of the life vest sized for containing said personal respirator tank and attached mouthpiece;
  • the inflatable bladder is typically one that is selectively activated by the wearer when appropriate to do so. This activation may occur by manually pulling a release cord.
  • the body may include an outer cover, to which the pocket is attached, and a separate internal inflatable bladder.
  • the body may solely include the inflatable bladder.
  • the pocket may be mounted on a backing portion, which provides local stiffening of the life vest casing.
  • the pocket may be permanently attached to the backing portion, such that the backing portion forms the rear of the pocket.
  • the pocket may be removably attached to the backing portion.
  • a backing portion may be provided on both sides of the life vest, such that the pocket may be moved between sides of the life vest.
  • the respirator tank includes an oxygen cylinder and a regulator.
  • the mouthpiece is typically attached directly to the regulator.
  • the respirator is activated by placing the mouthpiece into a person's mouth and commencing breathing, perhaps after exhaling sharply to clear the regulator of water before inhaling.
  • a purge button can be provided to automatically clear the regulator of water.
  • a mouthpiece cover may also be provided to protect the mouthpiece from dirt and debris.
  • the means tethering the personal respirator tank to the life vest may be a coiled strap, cord or other tie line.
  • the coiled strap may be made out of wire or plastic covered wire.
  • the tether may be made from a fabric.
  • a secondary pocket may be provided on the respirator tank pocket to at least partially house the tether and protect it from catching on objects.
  • An additional tether may also be provided between the mouthpiece cover and the pocket. Either tether may be detachable to allow the personal respirator tank to be removed from the life vest for reasons such as refilling.
  • Figure 1 is a perspective view of a life vest according to an embodiment of the present invention.
  • Figure 2 is a perspective view of the life vest of Figure 1 with the personal respirator tank removed;
  • Figure 3 is a perspective view of the pocket shown in Figure 2;
  • Figure 4 is a perspective view of the pocket of Figure 3 with the personal respirator tank inside;
  • Figure 5 is a perspective view of a life vest according to an alternative embodiment of the invention.
  • the life vest 10 is based on the standard inflatable aircraft type.
  • the life vest 10 includes a body 12 having an outer cover 13 generally in the shape of an inverted U, having a head supporting area 14 and two side areas 16, and an internal inflatable bladder (not shown) within cover 13. Straps with respective inter-engageable clasps 18 fit the body 12 to a person.
  • the straps include a waist strap 20 and a rear strap 22 that connects the head supporting area 14 to the waist strap 20.
  • Two leg straps 24 are also provided, which both extend centrally from the base of the rear strap 22 to spaced apart locations on the front of the waist strap 20.
  • the inflatable bladder is selectively activated by the wearer when appropriate to do so, by manually pulling a handle 26 connected to a release cord 28 to release the contents of a nitrogen bottle (not shown) or by blowing into a mouth tube (not shown).
  • Inflatable life vests are commonly worn by pilots, crew and passengers in helicopters that conduct any flying over water. If the helicopter ditches into water it typically inverts. If the passengers successfully remove their seat belts, open the doors and manoeuvre out of the cabin, they then inflate their life vest to assist them to float in the water until rescued. Unfortunately, all of the above steps are needed to be done quickly as there is little or no air present.
  • the life vest 10 of the present invention incorporates a personal respirator tank 30, which can be used as an emergency air supply for a person trapped underwater.
  • the respirator tank 30 includes an oxygen cylinder 32, a regulator 34 and a mouthpiece 36 attached directly to the regulator 34.
  • a respirator tank that could perform this function is the "Spare Air”TM produced by Submersible Systems, Inc.
  • the cylinder 32 is filled with compressed air under about 3000 psi operating pressure and would typically hold 48 litres of compressed air. This equates to approximately thirty breaths at sea level atmospheric pressure, which would allow a person time to escape from the cabin and swim to the surface.
  • a pocket 38 is provided on the body 12 on the front surface of cover 12 in one of the two side areas 16, although it will be appreciated that it could be provided on another component of the life vest 10.
  • the pocket 38 houses the respiratory tank 30 when not in use.
  • the placement of the pocket 38 on the front surface of one of the two side areas 16 makes access by either hand convenient, particularly when seated. The user may still be wearing a seat belt and the location of the pocket 38 makes the respirator tank 30 still easily accessible.
  • the pocket includes a backing portion 40 attached to cover 14, which is made from a stiffened material to provide local stiffening to the life vest casing to hold the respirator tank in the correct position.
  • a bottom hole 42 is provided in the base of the pocket 38 to let in water when withdrawing the respirator tank 30 from the pocket 38.
  • a means for tethering the respirator tank 30 to the life vest 10 is provided in the form of a coiled strap 44.
  • One end of the coiled strap 44 attaches via a loop arrangement around a neck 46 of tank 30 between the oxygen cylinder 32 and the regulator 34. The other end is threaded through a secondary pocket 48 on the outside of the pocket 38.
  • the secondary pocket 48 houses most of the coiled strap 44 and prevents it from catching on objects.
  • the coiled strap 44 exits through a hole 50 in the base of the secondary pocket 48 and is detachably connected to an attachment device 52 on the outside of the secondary pocket 48.
  • the coiled strap 44 tethers the respirator tank 30 to the life vest 10 both when it is contained in the pocket 38 and when it separates therefrom for use by the wearer of the life vest 10.
  • a cover 54 is provided to protect the mouthpiece 36 from dirt and debris.
  • An additional tether strap 56 may extend between the mouthpiece cover 54 and an attachment device 58 on the pocket 38.
  • the additional tether strap 56 may be detachably connected to the attachment device 58.
  • FIG. 5 An alternative embodiment of life vest 10 is shown in Figure 5. Respective backing portions 40 are attached to the cover 13 in the two side areas 16 of the body 12.
  • the backing portions 40 have a VelcroTM (hook and loop fastener) panel 60, or any other suitable fastening device.
  • the pocket 38 includes a corresponding VelcroTM panel (not shown) on its rear surface. This makes the pocket 38 removable, such that it can be attached to either side area 16 of the body 12.
  • This embodiment may be particularly useful for helicopter pilots, so that they can place their personal respirator tank 30 on their preferred side.
  • the advantage of the present invention is that a single unit is provided with the life vest having a personal respirator tank housed in a pocket on the body. This makes it easy for the user to simply grasp it, put the mouthpiece into their mouth, if necessary blow sharply to remove any water and commence breathing. The device is then fully operational. This gives the person enough air to escape and potentially to help other passengers that have been injured or are trapped. Access to the emergency air is very straightforward, and entails a minimal number of actions: an important attribute in a life- threatening situation where speed is critical and any complexity or possible source of confusion dangerous.
