BACKG&.Q0KD OF THE INVEN ION

This invention deals with explosive ordinance disposal (EOD) suits having improved blast-wave and. blast related projectiles protection, The EOD salts of this invention are a full body assembly that protects the explosive ordinance disposal so.ld.ier/technician from threats caused by bombs, mines and other explosive devices such as !B:Ds (improvised explosive devices) namely, the resulting blast—wave, including blast overpressure, impact and heat and, flams ingress and the resulting blast related projectiles, including ragmentation, impact and blunt trauma.

The suits of this invention feature the jacket inside the trousers which eliminates the weak point of other current BOD suits, namely, that the blast-wave and blast related projectiles can travel up from the explosion, most typically located on the ground, under the protective jacket, to the detriment of the EOD soldier/technician _* The suits of this invention use established material technolog together with new and innovative design to improve protection, comfort, and ergonomics . The materials are well -known to those in the art. For example, No e ® and Momex®/Re l r@ are two of such materials, Nomex and Kevl. r are trademarks owned by D Po t, Wilmington, Delaware,

THE INVSNTiOH

Thus, what is disclosed and claimed herei is a blast protective explosive ordinance disposal suit- The blast protective explosive ordinance disposal suit comprises at least a jacket and trousers, wherein the jacket and trousers are configured to be worn such that the jack is worn inside of the trousers.

Another embodiment of this invention is a combination of th jacket and trousers as set forth just above, a groin protector and over-boots .

Yet another srahodiraent is a combination set forth just above, hand protective mittens and at least one three-part blast plate.

Still another embodiment of this invention is a blast protective explosive ordinance disposal suit as set forth above, wherein, in addition, there is present an additional groin protector that is fitted beneath the trousers,.

combination of this invention. DBmiLBD DESCRJFTIOM OF JM DR&WXSGS .

Turning now to Figure 5, there is shown an illustration of a full complement of a suit 1 of this invention.

Figures 2 and 3 are a much clearer illustration of a combination of a jacket 2 and trousers 3 of this invention in which the jacket 2, which has been designed to fit under the trousers 3, is put on first and then the trousers 3, which have been designed to fit over the jacket 2, are put on next; the trousers 3 are held in place with braces (aka suspenders) « This is achieved by configuring the bulk and heft of the fabric of the jacket 2 and the trousers 3 so that the jacket 2 can easily fit under the trousers 3. This is achieved without detracting from the protection capability of the two components and results in enhanced blast-wave and enhanced blast related projectiles protection .

urning now to Figure 2, there is shown a full assembly of the jacket 2 and the trousers 3 of this invention showing reinforced

Cordura® patches 4 on the knees of the trousers 3, used to extend wear life of the trousers 3.

Figure 3 is an illustration of the back of the suit 1 showing the jacket 2 and the trousers 3 and Cordura patches 5 on the elbows of the jacket. Also shown in clearer detail are sleeves 6 of the jacket 2.

Figure 4 is a full front illustration of an internal (internal to the trousers of the suit 1) groin protector 7,

Turning now to Figure 5, there is shown a full front view of an illustration of a combination of this invention.

Thus, shown is the jacket 2 with sleeves 6, collar 8; trousers 3, with Cordura patches 4 on the knees of the trousers 3, over-boots 9; three part blast plates 10, harness 11 for the blast plates ID; and helmet 12.

The outer fabric of the suit is constructed, for example from

Nomex: certified flame retardant material. Cordura® patches can be fitted to the knees, and the blast plate pouch, and the elbows to extend wear life of the suit. Similar to prior art, fr.agmen.tation protection is achieved through the construction of multiple plies of water repell-ant treated aramid fibers contained within a nylon armor pack. Similar to prior art, blast overpressure reduction is achieved through a composite type of construction. However, enhanced blast-wave and blast related.

projectiles protection is achieved by a reconfiguration of the fabric and .materials of the jacket and the trousers so as to permit the trousers 3 to be worn outside o the entire jacket 2; wearing the trousers over the jacket channels the blast wa e up and away from the body vihereas in the convention l, design of prior art where the acket is worn over the trousers, the blast wave travels up the legs and under the jacket impacting the foody.

Optionally, there can be used in the combination, an integral back protector 14 as is shown i Figure 6. This component is CE certified at EH1621-2 level 2, having a thickness of approximate 18 mm, is breathable through air wave technology, waterproof, non-toxic and weighs in the neighborhood of about 400 to 500 grams.

Helmets useful in this invention include closed face helmet and open faced helmet. These helmets are constructed from 100 percent para ara id fibers providing excellent weight to performance

characteristics. The helmets are typically coated with epojcy paints in any desired color.

Thes helmets, comprise, generally, a comfort liner with two point harness with adjustable chin cup, removable visor, low noise helmet mounted fan assembly with, speed adjuster and battery charge indicator and. a helmet mounted light source. It also contains provisions for comm nic tions microphone and hearing ear pieces, all of which are known to those skilled in the art.

As an option, the suits can be provided with cooling systems for use in hot environments. The system is worn under the suit and consists of a Komejx body suit with a capillary tube network stitched into it. This is connected to a water reservoir and pump that

circulates ice water around the body. The cooling rate is adjustable so that a comfortable working temperature can be maintained. The greatest threats to the EOD soldier .technician arise from the faiast-wave overpressure and. blast related projectile fragments emitted, from the bo b/IED and other objects in the surrounding area which can impact and enter the body at supersonic speeds, The lightweight,

removable, composite ballistic panels fitted to the suit protect the upper torso, shoulder, neck, arras and legs while maintaining lightness and .maneuverability. In addition, the suit is supplied with rigid ballistic panels to provide added protection t the chest, lower abdomen and groin areas. The additional benefit of this invention is that the ability to wear the jacket 2 inside of the trousers 3

eiiiGinat.es a primary means of access of blast-wave overpressure and. blast related projectiles fr m impacting the SOD soldier/technician.

The pressure wave from a blast can cause severe damage to the lungs, eardrums and caus trauma in other body areas. The construction of the suit is such that both sets of ballistic panels limit the effects of the overpressure on the body while the collar completel encloses the neck area and overlaps the helmet. The design of the suit permitting the trousers 3 to be worn outside of the jacket 2 protects the body from the impact of overpressure travelling up from the blast.

The impact of the blast on the foody can cause differential acceleration between the head and torso which can break the: neck and cause damage to the spine. The suit can be fitted with an articulated, spine protector while the raised suit collar overlapping the helmet limits the differential acceleration between body and head.

The suits of this invention can be sised. from small to extra- large, that is, from a he ght of 156 cm to at least 195 era which is a height of from about 5 feet to more than 6 feet.

Thus, the suits of this invention have the key features of zoned armor systems providing exceptional fragment protection, three part, articulated blast plates, with high, performance helmet and visor and significant blast over pressure reduction.
