This application claims the benefit of Australian provisional patent application 2012904819 filed 1 Nov. 2012 and Australian complete patent application 2013203831 filed 11 Apr. 2013, which are incorporated by reference herein.
This invention relates generally in one aspect to garments of a kind that provide dual protection for a wearer. i.e., both body armour and a personal flotation device (PFD). The invention is of particular application to combat situations where personnel are at risk from both projectile injury and potential drowning. The invention has particular benefit in providing an ability for the wearer to rapidly adapt the equipment to changing circumstances. Different aspects of the invention co-operate to provide a versatile personal protection system.
Military personnel involved in waterborne operations are commonly provided with both body armour and a personal flotation device (PFD). Body armour is typically provided in a two part garment that is fastened both at the shoulders and about the waist. The armour may be plate armour and/or more modern soft armour based on super-strong fabrics, and is usually retained in pockets located to give protection to at least the torso, both back and front. PFDs will usually have an inbuilt compressed gas cylinder with an automatic water sensing valve or a hand-releasable valve.
One obvious problem with these conventional arrangements is that, in a combat situation, the PFD may suffer puncture damage, rendering it useless for its primary purpose just when it may most be needed. To address this problem, integrated structures have been proposed. For example, international patent publication WO 2006/054972 discloses an inflatable personal flotation bladder device that lies protected behind the strategic plate of a body armour vest when in its deflated and compressed state, from which an inbuilt compressed gas cylinder can expand the PFD on command. US patent application 2011/0004968 proposes a quite different approach, i.e. a multi-part body armour suit with inboard flotation foam. U.S. Pat. No. 6,659,689 discloses an inbuilt pair of inflatable items: a first ring around the abdominal region which is quick releasable for discardal, and an overlapping removable ring that inflates around the neck to encapsulate the crico-thyroid cartilage, protecting it from compression.
Integrated structures in which a flotation bladder is protected beneath an antiballistic armour layer are also disclosed in European patent application 1587382 and U.S. Pat. No. 7,080,411. The latter discloses a line of studs or hook and loop fastening that breaks apart when the bladder is inflated.
There have also been disclosures, e.g. in U.S. Pat. Nos. 7,182,662 and 3,475,774, of integrated garment structures, not armoured, in which a bladder inflates and expands out of the garment to provide PFD protection. US patent application 2011/0009020 discloses an inflatable bladder or flotation collar that can be inserted, attached or removed from a garment.
Integrated structures address the problem of protecting the uninflated bladder from puncture damage, but such structures may lessen the utility of the garment and its flexibility in different situations. For example, while it may be convenient to have a PFD with a protected inbuilt inflatable bladder, this can be the source of unnecessary discomfort when not required, and once inflated may be a serious encumbrance to motion. After deployment, the wearer may variously wish to retain the PFD and discard the armoured garment, or remain protected by armour and discard the PFD.
It is an object of the invention to provide improved configurations of armoured garment and personal flotation device that allow ready deployment of the PFD yet have inbuilt adaptability to a variety of field situations.
Reference to any prior art in the specification is not, and should not be taken as, an acknowledgment or any form of suggestion that this prior art forms part of the common general knowledge in Australia or any other jurisdiction or that this prior art could reasonably be expected to be ascertained, understood and regarded as relevant by a person skilled in the art.
The essential concept of the invention is to provide a garment and a PFD as separable components that preferably inter-engage in such a way as to provide antiballistic protection for both the wearer and the PFD, while allowing both ready deployment of the PFD and ready separation.
In a first aspect, the invention provides a garment comprising:
a panel adapted to comprise or retain body armour that protects a front region of the torso when the garment is worn;
respective laterally spaced side pockets that extend generally vertically at the front side regions of the torso when the garment is worn, which side pockets have openings at their upper ends to removably receive the respective arms of a generally U-shaped, deflated but inflatable personal flotation device (PFD), that thereby extends behind the neck and/or head of the wearer, which side pockets have outer side fastenings that are separable by the inflating PFD arms to thereby allow the arms to fully expand.
Preferably, when received within the side pockets, the arms of the PFD lie behind and therefore protected by respective portions of the body armour.
In a second aspect, the invention provides an inflatable personal flotation device (PFD), comprising:
a casing defining a central portion and a pair of laterally spaced, generally aligned arms extending therefrom whereby to define a generally U shaped configuration; and
bladder means within the central portion and laterally spaced arms, able to receive and retain compressed gas for inflating the personal flotation device;
wherein at least the central portion of the casing is at least partially inlaid or overlaid by armour to protect the bladder means from puncture by impinging projectiles.
In a third aspect, the invention provides a personal protection system comprising a garment according to the first aspect of the invention and an inflatable personal flotation device (PFD) according to the second aspect, the arrangement of the side pockets of the garment and the armour of the inflatable PFD being such that, when the PFD arms, deflated and unexpanded, are received within the side pockets of the garment, the bladder means of the PFD is largely and preferably wholly protected on at least one face by the combined armour of the garment and the PFD.
In an embodiment, the garment may be the front garment of a multi-part body amour vest.
The casing preferably comprises fastenings separable by the inflating bladder means, thereby allowing the bladder means to fully expand. Advantageously, these separable fastenings of the casing and of the PFD are generally aligned with the separable outer side fastenings of the side pockets of the garment.
The separable fastenings are preferably zip fasteners.
The inflatable PFD and the garment are preferably fitted with quick release couplings for securing the two together. In a convenient arrangement, these couplings comprise cooperating eyes or loops linked by a cord or the like arranged to be withdrawn by manual action, for example by a pull device at an end of the cord. There are preferably couplings of this kind at each side of the torso when the garment and PFD are being worn, and in the region of the neck or shoulders.
The garment may be a front shield only, or may be part of a plural component vest to be worn on the torso with both front and back protection.
As used herein, except where the context requires otherwise, the term “comprise” and variations of the term, such as “comprising”, “comprises” and “comprised”, are not intended to exclude further additives, components, integers or steps.
The invention will now be further described, by way of example only, with reference to the accompanying drawings, in which:
Vest 40 is in many respects quite conventional, comprising a front garment 50 (shown separately in
In the case of front vest garment 50 there is a third innermost fabric panel 58 that is contiguous with side bands 56 and is stitched centrally to panel 55 along a vertical line 59 (
Turning then to the PFD (shown separately in
In its deflated, compressed state, PFD 20 is a generally flat and flexible U-shaped object. It is assembled to garment 50 of vest 40 by disengaging the flaps 48 and inserting the arms 26, 27 down into the front side pockets 45 of the garment. When they are fully home, flaps 48 are removably secured. They may, for example be pressed onto an appropriate respective hook and loop pad 47 (
As seen in
Zip fasteners 28, 46 are configured and arranged so that they may be linearly burst open in turn by bladder 24 when the wearer pulls the finger cord 30 to release the valve on the compressed gas cylinder or when the valve is automatically released by a water sensitive switch. Preferably the bladder is configured so that the central or yoke portion 25, expands first (
In other embodiments, the compressed gas cylinder may be substituted with any suitable vessel or means for providing gas to inflate the bladder 24.
When inflation is complete, the wearer has a fully provided PFD correctly in position. By having the central or yoke portion 25 of the PFD already in position before inflation, its correct location, after expansion is assured. The PFD may be protected by a mix of its own armour 85 and the armour 70 of the vest garment in which it is installed.
The manner in which the two components of the personal protection system 10 are held together for easy separation will now be outlined with particular reference to
Releasable couplings 100, 102, 103 (
It will be understood that the invention disclosed and defined in this specification extends to all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the invention.
