This invention relates to protective garments, and in particular, but not limited to, protective garments for protecting military and emergency service personnel including police during active service.
Military personnel often work in hazardous environments and are frequently exposed to ballistic threats such as bullets and fragments from explosive devices such as bombs and roadside IEDs (improvised explosive devices). Personnel operating in these environments may be issued with a sleeveless protective jacket for wearing in combination with standard military uniform. The protective jacket comprises front and rear pockets each extending over the front and rear torso regions for receiving a ballistic resistant plate, typically composed of a composite of multiple layers of ballistic resistant fabric such as an aramid material and embedded epoxy resin which are heat pressed together. The front and rear protective plates assist in preventing bullets and fragments penetrating the thoracic cavity and damaging vital organs.
According to one aspect of the present invention, there is provided a protective garment for protecting personnel, comprising a torso portion formed of flexible material, and left and right arm sleeves extending from said torso portion, each sleeve comprising a flexible material and including retaining means for retaining a protective armour element to the sleeve.
Advantageously, this arrangement provides a protective garment for protecting areas of the arm susceptible to injury during combat.
In some embodiments, the sleeves may be formed of a lightweight material.
In some embodiments, the sleeves may be formed of a breathable material, for example a mesh-like material.
In some embodiments, the sleeves may be formed of a material which is capable of stretching.
In some embodiments, the torso portion may be formed of a material having one or more of the same properties of the sleeve material.
In some embodiments, each sleeve has an upper arm portion and a lower arm portion, and the retaining means comprises a first retainer positioned to retain a first protective element or plate in the upper arm portion, and a second retainer for retaining a second protective element or plate in the lower arm portion.
In some embodiments, the retaining means comprises at least one pocket provided on the sleeve.
In some embodiments, the pocket is formed on the inside of the sleeve. Advantageously, with the pockets formed on the inside of the sleeve, the material of the sleeve itself overlies the protective element or plate and assists in urging and holding the protective element or plate against the wearer's arm. In other embodiments, the pocket may be formed by attaching a web of material to the outside of the sleeve, and may be secured thereto to have a similar effect of urging the protective or plate against a wearer's arm.
In some embodiments, the pocket has an opening on at least one of the inside of the sleeve and the outside of the sleeve for permitting insertion of a protective element or plate therein. Advantageously, the use of a pocket having an opening allows the protective element or plate to be removed from the protective garment so that different protective elements or plates can be used depending on the level of protection required and the prevailing threat. Also, the removability of the plates allows the protective garment to be more easily laundered.
In some embodiments, the opening of the pocket may be closable, for example by any suitable fastening means such as a surface contact type fastener (e.g. hook and loop fastener). This allows the opening of the pocket to be quickly released and the protective elements or plates to be quickly and conveniently inserted or removed.
In some embodiments, the pocket comprises a material having any one or more similar characteristics of the material forming the main part of the sleeve and/or torso portion. In other embodiments, the pocket(s) may comprise an opaque material (e.g. woven, non-mesh) such as Cordura™ or similar material.
In some embodiments, each sleeve has an opening formed therein in the underpart of the sleeve near the junction between the sleeve and the torso portion, and/or in the torso portion adjacent the underpart of the sleeve. Advantageously, the opening reduces the heat load and facilitates cooling of the underarm region, increases mobility, and allows the weight of the protective garment to be substantially reduced. The opening may extend from the junction between the torso portion and the sleeve and may extend along a major part of the upper arm, and in some embodiments, may extend further, for example to the elbow region or below.
In some embodiments, each sleeve further comprises tightening means for tightening the sleeve against a wearer's arm. The tightening means may be disposed within a region of a protective element or plate such that the tightening means tightens the protective element or plate against a wearer's arm. For example, in embodiments where the sleeve includes protective elements for the upper and lower arms, a tightening means may be arranged to tighten the upper protective element against the upper arm and a further tightening means may be arranged to tighten the lower protective element against the lower arm.
In some embodiments, the torso portion comprises a front portion and a rear portion, and one of the front portion and the rear portion comprises left and right side flaps for securing to the other of the front portion and rear portion. Advantageously, this allows the torso portion to be tightened and fitted against a wearer's body.
In some embodiments, the front of the torso portion can be opened and may for example comprise left and right flaps and a quick release fastener to allow the flaps to be opened. The quick release fastener may for example comprise a hook and loop fastener (e.g. Velcro).
In some embodiments, the protective element comprises a protective plate having a pre-formed transverse curvature to assist in conforming the plate to the shape of the region of a wearer's arm when in use.
In some embodiments, each protective plate is flexible to allow the transverse curvature to be varied. Advantageously, this system allows the protective plate to be bent as needed to effectively conform to the shape of a wearer's arm for increased comfort, and so that the whole of the surface area of the plate is encouraged to fit tightly and accurately to a wearer's arm. This assists in preventing relative movement between the plate and the arm, when the plate is subjected to forces along or transverse to the surface of the plate, as caused by, for example, motion of the wearer.
In some embodiments, each protective plate comprises at least one layer of ceramic and/or plastic material, e.g. polycarbonate, and at least one layer of ballistic resistant material, for example, a ballistic resistant fabric such as an aramid fibre-containing fabric, e.g. Kevlar, Dyneema, Twaron (or similar material). The protective plate may further include a layer of foam backing for increased comfort, thermal insulation and to reduce back face deformation of the plate when subjected to high velocity ballistic fragments, particles, bullets or other objects.
According to another aspect of the present invention, there is provided a protective garment for protecting personnel, comprising left and right leg protectors, each leg protector comprising a legging formed of flexible material and having retaining means secured thereto for retaining at least one protective element to the legging.
In some embodiments, the material comprises a lightweight material.
In some embodiments, the material comprises a breathable material, for example, a mesh-like material.
In some embodiments, each legging comprises an upper portion for covering an upper portion of a wearer's leg above the knee, and may further comprise a lower portion for covering at least a portion of a wearer's lower leg below the knee.
In some embodiments, each legging includes a front portion, and the front portion has an opening formed therein in the knee region. Advantageously, this arrangement increases the flexibility of the garment in the region of the knee, and also reduces the weight of the garment.
In some embodiments, the retaining means comprises at least one pocket provided on each legging. At least one pocket may be formed on the inside of each legging. Advantageously, by forming the pocket on the inside of each legging, the material of the legging overlies the protective element or plate and can therefore urge the plate into more intimate contact with the wearer. Alternatively, each pocket may be formed on the outside of the legging to have a similar effect of urging the protective element against a wearer's leg.
In some embodiments, each legging extends substantially to a waist region, and the leggings are connected together at the waist region.
In some embodiments, each legging defines an inside edge between the waist region and crotch region thereof, and at least a portion of the edges are disconnected. Advantageously, this arrangement in which there is an absence of material between the waist and crotch region provides increased flexibility, cooling and comfort.
In some embodiments, the protective element comprises a protective plate.
Protective plates may be provided for protecting any one or more of the front thigh, rear thigh, buttock region, front lower leg and rear lower leg.
In some embodiments, each protective plate comprises at least one layer of ceramic or plastic material (e.g. polycarbonate), and at least one layer of a ballistic resistant material, for example an aramid-based fabric such as Kevlar, Twaron, Dyneema or similar material. The plastic or ceramic material may be placed in front of the ballistic resistant material or vice versa. At least one protective plate may further comprise a foam backing or similar backing for increased comfort, thermal insulation and reduction of back face deformation when the front of the plate is subjected to high velocity impacts from sharp objects such as bullets and shrapnel.
In some embodiments, each protective plate has a preformed transverse curvature to generally conform to the shape of the portion of the wearer's leg where the plate is to be worn.
In some embodiments, the protective plate is flexible so that the transverse curvature can be varied to conform to the shape of a wearer's leg. Advantageously, this allows the plate to be held more closely to the wearer's leg and to reduce relative movement between the plate and leg, for increased comfort.
In some embodiments, each legging comprises tightening means for tightening a legging about a wearer's leg. The tightening means may be positioned such that it acts to tighten a protective element or plate to the wearer's leg.
Examples of embodiments of the present invention will now be described with reference to the drawings, in which:

Advantageously, in embodiments of the present invention, the vest and pants provide a lightweight, breathable carriage system for carrying protective elements to protect extremities of the body such as the arms and legs to complement and enhance existing standard military jackets, which only protect the torso region. Embodiments of the protective vest and/or pants may be treated with an anti-infrared reflective treatment to reduce or prevent the material reflecting infrared light, so that the wearer cannot be observed in darkness under infrared light.
An example of a protective plate which may be used as an element with the vest or pants is shown in
A cover (not shown) may be provided to cover the protective plate, and may be formed of any suitable material, such as nylon, and the material may be water resistant, or waterproof.
The protective plate may have a preformed, transverse curvature generally shown at 409 between its side edges 411, 413 to assist the plate in conforming to the shape of a wearer's limb in the region at which the plate is to be worn. Alternatively, or in addition, the protective plate structure may be flexible so that it can fit more accurately to the individual's shape for increased comfort and also to reduce relative movement between the plate and a wearer (by increasing surface contact over its area).
In embodiments of the vest and/or pants, the vest or pant shell material may be abrasion resistant.
The protective vest or pants may be formed of a material to reduce its infrared signature.
At least one of the vest and pants may be provided with a quick release mechanism to facilitate donning and doffing.
One or more protective plates may have a foam backing for heat dissipation, back face deformation and comfort.

Embodiments of the invention provide lightweight extremity protection. The protective plates may provide protection to fragmentation from various threat levels, which may include standard test threat levels of 2, 4, 16, 64 g RCC (Right Circular Cylinder). One or more protective plates may also provide protection from 9 millimetre FMJ (full metal jacket) bullets.
Advantageously, the vest and/or pants have a low thermal burden and provide an exoskeleton carriage system for carrying an adaptive armour system comprising a plurality of protective elements (e.g. plates).
The carriage system allows the protective elements to be intimately secured to the limbs of a wearer so that they move together with the wearer's limbs, and remain effectively integrated with the wearer, even when subjected to shock.
The protective system is particularly applicable to protect dismounted soldiers, although the protective system may be applied to any other personnel, for example, those operating in a hazardous environment.
Embodiments of the present invention may provide protection over a range of areas of the limbs. Studies show that the percentage of injuries in different areas of the body sustained by military personnel when in combat, are as follows:—
1) upper arm 16%
2) lower arm 11%
3) shoulder 8%
4) thigh 19%
5) lower leg 18%
6) lower extremities hand/elbow 11%
7) knee/foot 11%
8) hip/buttock 5%.
A diagram showing the percentage of injuries inflicted on different parts of the human anatomy is shown in
Advantageously, embodiments of the invention can be adapted to protect limbs and limb regions which are traditionally difficult to protect and at the same time maintain operational effectiveness/flexibility and user confidence.
