Description




FIELD OF THE INVENTION




This invention relates to body protective garments and more particularly to protective garments which will protect a body from weapons which inflict stab or ballistic wounds.




BACKGROUND OF THE INVENTION




Various stab resistant articles or garments have been worn by prison corrections officers and other types of security, military or law enforcement personnel. Such stab resistant articles are designed to prevent bodily penetration as a result of stabbing or slashing from sharp objects or weapons. Unfortunately, these protective articles were generally rigid shields which were externally worn and were constructed of heavy, bulky and inflexible metal components such as titanium or other extremely hard metal alloys. The metallic composition of these cumbersome external vest shields must be of sufficient thickness, rigidity and strength to stop impacts imparted by an attacker, such as a prison inmate, using a sharp knife, pick, shank or the like.




Disadvantageously, the bulk and rigidity of such metallic vest garments rendered it uncomfortable to wear. Furthermore, it is rather difficult for the wearer of a rigid vest such as a corrections officer to move and maneuver around quickly and easily which is important especially if the wearer is being attacked. The stiffness of these externally worn body shield vests are uncomfortable to wear in a sitting position since the lower edges often press firmly against the stomach, hip and side areas of the wearer, as well as, the top of the shield placing pressure on the wearer's throat and chin areas. Moreover, the weight of such known metallic shields caused significant fatigue to the security personnel wearer over the time for the wearer's working shift. Accordingly, such known puncture resistant articles often prove to be ineffective predominantly due to the fact that the potential wearer prefers not to wear the bulky torso shield rather than tolerating its discomfort.




Another, and perhaps a more significant problem with such rigid metallic alloy puncture resistant vests is that they were not concealable. These known cumbersome shield vests were almost exclusively externally worn and even if they were not worn externally, the bulky nature of such articles make it obvious to a would be attacker that the wearer (corrections officer, etc.) is wearing a protective puncture or stab resistant metallic shield vest. Since the worn vest article cannot be concealed the potential attacker is more prone to stab or slash at a vital area away from the vest such as the lower abdomen, groin, neck or head area. Not only is any element of surprise on the part of the wearer removed by the unconcealed nature of such cumbersome rigid vests, it is highly impractical if not impossible for the undercover personnel to wear such bulky items.




However, significant advancements have been made to construct wearable and concealable soft body armor that protects the wearer from puncture wounds such as found in U.S. Pat. No. 5,960,470 assigned to Second Chance Body Armor, Inc. These puncture resistant garments were intended for that purpose and carried multiple layers of a high density weave or pick and end counts.




Further advancements have been recently made in developing bi-component ballistic and stab resistant wearable and concealable garments. These developments by Second Chance Body Armor, Inc. are described in U.S. Pat. No. 5,960,470. The bi-component garment contains a woven puncture resistant panel constructed of multiple plies of relatively high density woven fabric used in conjunction with a ballistic resistant panel which was constructed of either multiple plies of woven fabric of a relatively lower density weave or composite materials. This versatile bi-component garment provides the wearer with puncture and ballistic resistance protection and concealability along with a level of comfort afforded that construction.

DETAILED DESCRIPTION




Referring to

FIGS. 1-3

, multi-component stab and ballistic resistant garment


10


is shown having two sub-panels


12


and


14


. In this assembly, sub-panel


12


is designed to resist penetration from stab or slash attacks with sharp objects while sub-panel


14


is designed to resist ballistic penetration from discharge of a ballistic weapon or the like. Stab resistant sub-panel


12


is positioned at the strike face of garment


10


and provides this bi-component construction of garment


10


with an enhanced ballistic performance. Ballistic resistant sub-panel


14


is positioned underlying stab resistant sub-panel


12


such as at a body side portion of the garment and provides an enhanced or synergistic performance to the stab resistance of this multi-component construction of garment


10


. In the example seen in

FIGS. 1-4

, the stab resistant sub-panel


12


overlies the ballistic resistant sub-panel


14


forming multi-component stab and ballistic resistant pad


11


. As discussed herein, the ballistic resistant sub-panel


14


is constructed of woven ballistic resistant sheets wherein at least a portion of the stab resistant sub-panel and at least a portion of the ballistic resistant sub-panel are aligned with one another.




In

FIG. 1

, a partially broken away stab and ballistic resistant pad cover


16


is shown which encompasses and encloses sub-panels


12


and


14


of multi-component pad


11


. Pad cover


16


is secured snuggly around sub-panels


12


and


14


and is typically stitched around the perimeter to itself. The snug fit of pad cover


16


to sub-panels


12


and


14


assists in providing support to sub-panels


12


and


14


in maintaining alignment of the sub-panels to each other. It is desired to have pad cover


16


provide garment


10


with breathability and protection of the sub-panels from degrading aspects of contaminants such as body oils and salts, fuel spills, soaps, detergents, urine blood and other undesirable contaminants. A selective construction of pad cover


16


would have it constructed of a water proof and vapor permeable material such as GORE-TEX, manufactured by W. L. Gore & Associates, Inc. of Newark, Del. Under such construction, performance integrity of sub-panels


12


and


14


are maintained, longevity is enhanced and desired comfort in the form of moisture vapor breathability is provided to the wearer. Alternatively, panel cover


16


may selectively be constructed of woven nylon material having a plastic coating or White Supplex treated with dynamic water repellent, a highly breathable material formed from nylon fiber by E. I. DuPont de Nemours & Company of Wilmington, Del.




Garment


10


having pad


11


enclosed in pad cover


16


may, in turn, be positioned into a carrier, often constructed of cloth or other common material which is constructed for mounting onto the wearer concealed under the wearer's clothing.




In referring to

FIG. 1

, sub-panels


12


and


14


are secured together with bar tac lines of stitching


18


and


20


. Bar tac stitches


18


and


20


penetrate through both sub-panels


12


and


14


and are positioned toward the top portion of garment


10


. This positioning provides flexible stab resistant panel


12


to be suspended to overlie ballistic resistant panel


14


. Moreover, since bar tac stitches


18


and


20


penetrate sub-panels


12


and


14


, they are strategically positioned proximate the perimeter of the multi-component pad


11


near shoulder areas of the wearer and away from primary locations of stabbing or ballistic impact. Additionally, bar tac stitching


18


and


20


provides assistance in maintaining sub-panels


12


and


14


in alignment to one another optimizing performance of garment


10


.




A wide variety of fibers may be selectively used in bar tac stitching


18


and


20


such as rigid-rod lyotropic liquid crystal polymer fiber formed from poly(p-phenylene-2, 6-benzobisoxaxole) (PBO) or as referred to as Zylon a registered trademark of Toyobo Co. Ltd. of Osaka, Japan, aramid fibers such as referred to as Twaron a registered trademark of and manufactured by Acordis, Inc. of Wuppertal, Germany or such as referred to as Kevlar a registered trademark of and manufactured by E. I. DuPont de Nemours & Company of Spruance, Virginia or ultra high molecular weight polyethylene fiber such as referred to as Spectra a registered trademark of and manufactured by Allied Signal & Co. of Morris County, N.J. The denier of these fibers may selectively range from 200 to 1500.




In referring to the example of

FIG. 2

, stab resistant sub-panel


12


is constructed of three components or layers. The three layers include top layer


22


, bottom layer


24


and a metallic cloth layer


26


interposed between layers


22


and


24


. Both top layer


22


and bottom layer


24


may selectively comprise one or more sheets or layers of woven fabric. In the present construction, the top and bottom layers


22


and


24


of fabric sheets are each woven with Zylon PBO fiber of 500 denier in a weave of 45 fibers per inch of warp by 45 fibers per inch of weft. Alternatively, a wide range of fibers are contemplated to be selectively used in the weave construction of top and bottom layers


22


and


24


including Zylon PBO, aramid and ultra high molecular weight polyethylene fibers, all of which are described above as a selection of fibers to be selectively used for the bar tac stitching


18


and


20


. Likewise, a wide range of deniers for these selective fibers are contemplated from 200 to 1500.




As seen in

FIGS. 1-3

, top and bottom layers


22


and


24


are constructed to be generally approximately the same size and shape and are secured together, as discussed below, generally in registration with each other.




An enlarged view of the respective weaves of top and bottom layers


22


and


24


are shown in

FIGS. 4

,


5


and


6


. In

FIG. 5

, an enlarged view of the plain weave of top layer


22


is shown and similarly, in

FIG. 6

an enlarged view of the plain weave of bottom layer


24


is shown. As can be seen in

FIG. 5

, warp


28


and weft


30


are oriented in a directions of substantially horizontal and substantially vertical respectively. On the other hand, in contrast, the warp


32


and weft


34


of bottom layer


24


are positioned each angularly displaced approximately 45 degrees out of alignment with warp


28


and weft


30


of top layer


22


. A sharp object that encounters or comes into contact with top layer


22


of panel


12


through a stabbing or slashing condition engages penetration resistance from the fibers of warp


28


and weft


30


. As the weapon proceeds to exert force through the interposing metallic cloth layer


26


and encounters the bottom layer


24


, the fibers in warp


32


and weft


34


of bottom layer


24


, as seen in

FIG. 6

, provide penetration resistance. Irrespective of angle of attack of a sharp object, the present invention is providing double the number of directions of fiber alignment, with the nonalignment of the warp and weft between top layer


22


and bottom layer


24


, providing more different angles of cut resistance to a blade.




A balanced plain weave is shown in

FIGS. 5 and 6

, however, it should be understood an imbalanced plain weave may be selectively used and that various other balanced and imbalanced weaves of one to four less picks to warp ends are contemplated to be used such as basket, twill or satin as well as other commonly known weaves. The weaves can be selectively used in the ranges from 20 by 20 to 45 by 45 in fibers per inch in the warp and weft directions whether balanced or imbalanced. Thus, the weave for the layers of woven fabric of the stab resistant sub-panel


12


ranges from 20-45 warp fibers per inch and 20-45 weft fibers per inch.




In one example, warp


28


and weft


30


of top layer


22


,

FIG. 5

, are angularly displaced and therefore not aligned with the corresponding warp


32


and weft


34


of bottom layer


24


as seen in FIG.


6


. The angular displacement provides additional directions of penetration resistance for the stabbing and slashing encounters and therefore enhances the effectiveness of the garment. The angular displacement between warp


28


of the top layer


22


and warp


32


of bottom layer


24


can selectively range from 22.5 degrees to 45 degrees and correspondingly, likewise the angular displacement between weft


30


of top layer


22


and weft


38


of bottom layer


24


can selectively range between 22.5 degrees to 45 degrees of angular displacement.




The third component or layer of stab resistant panel


12


is metallic cloth


26


. In referring to

FIGS. 2

,


4


and


7


metallic cloth


26


is selectively constructed of a layer of No.


9


chain mail constructed of stainless steel fabricated by Whiting & Davis, Inc. of Attleboro Falls, Mass. No.


9


chain mail includes the specifications of a diameter of wire of 0.0311 inches; links, rings or circles of 0.275 inches outside diameter; and a weight of 91 ounces per square yard. Metallic cloth


26


, as seen in

FIG. 7

, in this particular construction of chain mail includes the interlinking of smaller geometric units or circles


27


constructed of strong stainless steel forming a strong flexible cloth having small openings


29


within the cloth. The geometric units


27


interlinked together will resist impact from the stabbing object and will tend to trap and resist penetration of the sharp object within the small openings


29


within its construction.




Alternatively, selective constructions of metallic cloth


26


are contemplated. For instance, a wide range of chain mails may be used that are constructed of stainless steel or titanium and which vary in weight and size such as chain mail Nos.


9


and


5


and the like. For example No.


5


chain mail manufactured by Whiting & Davis have specifications of a diameter of wire of 0.0215 inches; links, rings or circles of 0.160 inches outside diameter and a weight of 83 ounces per square yard.




Additional alternative constructions for metallic cloth layer


26


can be selectively used. These constructions include such metallic cloths as monofilament wire mesh, multi-stranded wire mesh, monofilament knit wire and multistranded knit wire. The composition of these wire mesh and knit wire constructions will vary and may include stainless steel or titanium and will vary in weight. Additionally, one or more layers of the metallic cloth can be used in constructing layer


26


.




In constructing stab resistant sub-panel


12


, one, two or more layers of metallic cloth


26


may be used. In the construction where there are two or more layers of metallic cloth being used, each layer would be positioned to overlie one another. All the layers may be of the same construction or various layers may be formed of different constructions such as chain mail, wire meshes or knit wire.




In stacking metallic cloth layers


26


to overlie one another, a similar approach can be taken as with woven fabrics discussed herein. The woven fabric sheets of top layer


22


or bottom layer


24


may selectively have warps and wefts of successive sheets in angular rotational nonalignment with one another wherein alternating sheets may have their warps and wefts in alignment. The woven fabrics may have groups of sheets of warps and wefts in alignment with one another but adjacent groups of sheets have their warps and wefts in angular rotational nonalignment with one another wherein alternating groups of sheets may have their warps and wefts in alignment with one another. As such, in one example a plurality of top layers and bottom layers may selectively each have groups of at least two layers of woven fabric in which individual layers within each group have warp and weft fibers in alignment with one another. Adjacent groups, having at least two layers, may selectively have the warp and weft fibers of the layers of woven fabric angularly displaced relative to one another. In this example, the warp and weft fibers of the layers of alternating groups, such as every other group, having at least two layers, may be substantially in alignment with one another.




This arrangement of layers may selectively apply to the metallic cloth


26


. As seen in the example of

FIG. 7

, chain mail has a matrix of interlocking circles that generally align in transverse rows similarly to a warp and weft of a fabric, likewise knit wire has a matrix of interlocking loops that generally align in transverse rows similarly to a warp and weft of a fabric and mesh wire includes numerous weaves such as plain, twill and other common weaves which generally form a matrix of fibers similar to a warp and weft of a fabric. In utilizing these various constructions of metallic cloths, the same application of orienting the warps and wefts of layers of the metallic cloth can be applied, as is applied to woven fabrics described herein, wherein their transverse rows or warps and wefts are angularly displaced out of alignment as described above for the woven fabrics. Another configuration of out of alignment warps and wefts for metallic cloth layers may also include generally aligning the warp and weft rows (circles, loops or weaves, etc.) of one metallic cloth sheet with the warp and weft rows of an adjacent and overlying other metallic cloth sheet, wherein the warp and weft rows of the one metallic cloth sheet may be laterally shifted so as to have at least one of one warp row and one weft row of the one metallic sheet overlap two corresponding adjoining warp rows and two corresponding adjoining weft rows, respectively, of the another metallic cloth sheet. Alternatively, the layers of metallic cloth


26


may have their transverse rows or warp and weft positioned in alignment and generally in registration over one another.




As described herein, the multi-component stab and ballistic resistant pad


11


has stab resistant sub-panel


12


constructed of at least one layer of metallic cloth


26


interposed between at least two layers


22


and


24


of woven fabric. Top layer


22


and bottom layer


24


may each comprise one or more layers of woven fabric of high strength fibers. In one example, as discussed herein, a plurality of top layers


22


of woven fabric are placed in overlying relationship at a strike side of the stab resistant sub-panel


12


and a plurality of bottom layers


24


of woven fabric are placed in overlying relationship at a side opposite the strike side of the stab resistant sub-panel with the metallic cloth interposed between the top layers and bottom layers of woven fabric.




Referring now to

FIGS. 1-3

, stitches


43


are used to secure all three components or layers


22


,


24


and


26


together forming stab resistant panel


12


. Additionally, stitches


43


maintain metallic cloth layer


26


in a generally flat and secure position within panel


12


. Stitches


43


pass through layer


22


, metallic cloth


26


and bottom layer


24


securing all three components together. Stitches


43


follow a pattern proximate to the perimeter of metallic cloth


26


and perimeter of layers


22


and


24


. Stitches


43


pass through top layer


22


and through metallic cloth


26


and through bottom layer


24


securing the proximate perimeter of metallic cloth


26


to an area approximate to the perimeters of both layers


22


and


24


of panel


12


. To further secure metallic cloth


26


within panel


12


and maintain its flexible structure in a substantially flat position within panel


12


, stitches


43


are positioned in a cross pattern over panel


12


and through panel


12


, as seen in

FIGS. 1-3

. In the cross pattern formed by stitches


43


, one row of stitches


43


are positioned from an upper right hand location of metallic cloth


26


and layers


22


and


24


to a lower left hand location of the metallic cloth


26


and layers


22


and


24


. Similarly, another row of stitches


43


are positioned from an upper left hand location of metallic cloth


26


and layers


22


and


24


to a lower right hand location of metallic cloth


26


and layers


22


and


24


.




Now referring to the ballistic panel


14


, as seen in FIGS.


3


and


8


-


11


, this panel is constructed of multiple plies or sheets of woven ballistic resistant material. In one example embodiment, ballistic panel


14


selectively has


32


sheets, plies or layers


47


, as representatively shown in

FIG. 11

, with each ply, layer or sheet constructed of Zylon PBO fiber of 500 denier and is woven in an imbalanced weave of 25 by 24 fibers per inch in the warp and weft directions, respectively. A wide range of fibers are contemplated to be selectively used in the weave construction of the sheets or plies


47


in panel


14


including PBO, aramid and ultra high molecular weight polyethylene fibers as described above for fibers used for bar tacs


18


and


20


. Additionally, a wide range of sheets


47


for constructing panel


14


may selectively be employed, ranging from 18 to 42 in number. Likewise, a wide range of deniers for these fibers are selectively contemplated from 200 to 1500. As seen in

FIGS. 5 and 6

and

FIGS. 9 and 10

, the layers of woven fabric


22


,


24


of the stab resistant sub-panel


12


have weave which is tighter than the weave for the sheets


47


of the ballistic resistant sub-panel. In this embodiment, a higher number of warp fibers


28


,


32


and weft fibers


30


,


34


per inch,

FIGS. 5 and 6

, are employed in the layers


22


,


24


of woven fabric for the stab resistant sub-panel


12


than the warp fibers


50


,


54


and weft fibers


52


,


56


per inch,

FIGS. 9 and 10

, employed in the ballistic resistant sheets


47


such that the woven fabric layers of sub-panel


12


have a tighter weave than the weave in the ballistic resistant sheets of sub-panel


14


.




An imbalanced plain weave may be utilized in the sheets of ballistic resistant sub-panel


14


. A balanced plain weave may also be selectively used as could a wide variety of imbalanced and balanced weaves. An imbalanced weave having one to four less picks (weft fibers), than warp ends per inch are contemplated to be selectively used as are basket, twill or satin as well as other commonly known weaves. These weaves can range from 20 by 20 to 45 by 45 in fibers per inch in the warp and weft directions whether balanced or imbalanced.




In referring to

FIG. 8

, a first sheet


46


and a second underlying sheet


48


is shown. It is understood that sheets


47


in panel


14


will all be substantially the same size and shape and overlie one another generally in registration with one another. An enlarged view of the respective weaves of first sheet


46


and second underlying and adjacent sheet


48


are shown in

FIGS. 9 and 10

, respectively. As can be seen in

FIG. 9

, warp fibers


50


and weft fibers


52


are oriented in a direction of substantially horizontal and substantially vertical, respectively. On the other hand, in contrast, the warp fibers


54


and weft fibers


56


of second or underlying sheet


48


, as seen in

FIG. 10

, are positioned each angularly displaced approximately 45 degrees out of alignment with the warp


50


and weft


52


of first sheet


46


. A knife, blunt force or ballistic impact onto or through to ballistic resistant sub-panel


14


provides a dispersement of energy along warp


50


and weft


52


in FIG.


9


and along warp


54


and weft


56


directions in FIG.


10


. This angularly displaced warp and weft of adjacent successive sheets


46


and


48


provide double the number of directions of alignment of fibers thereby significantly enhancing dispersement of the knife, blunt force or ballistic impact energy.




It should be understood that the absolute orientation of the warp and weft of the above described woven sheets


46


and


48


is not a necessary criteria for this construction. The important matter in this construction is that warp


50


and weft


52


of sheet


46


are angularly displaced from the corresponding warp


54


and weft


56


of adjacent sheet


48


. The angular displacement provides additional directions of for dispersal of energy at the time of a ballistic impact and enhances the knife, blunt force or protective resistant capabilities. The angular displacement between warp


50


of sheet


46


and warp


54


of sheet


48


can selectively range from 22.5 degrees to 45 degrees and correspondingly, likewise the angular displacement between weft


52


of sheet


46


and weft


56


of sheet


48


can selectively range from 22.5 degrees to 45 degrees.




In the present construction, with regard to the multiple sheets


47


that comprise panel


14


, each successive sheet


47


has their warp and weft angulary displaced and therefore out of alignment with the warp and weft of the sheet


47


to which it is adjacent. The adjacent sheets


47


in panel


14


are oriented as described above for sheets


46


and


48


in which the respective warp and wefts of each of the sheets are angularly displaced from one another. The next adjacent underlying sheet from sheet


48


will have its warp and weft angulary displaced from the warp and weft of sheet


48


, however, its warp and weft can be aligned with the warp and weft of sheet


46


. Thus, each successive sheet within panel


14


will have a different alignment of warp and weft to its immediately adjacent sheets positioned on either side of it, however, this construction would permit having each alternating sheet


47


within panel


14


have the same alignment of warps and wefts and each adjacent sheet


47


have their warps and wefts angularly displaced and therefore not aligned with one another.




Similarly, the construction of panel


14


can have a group of at least two successive sheets


47


with their warps and wefts in alignment to one another and then have the following or second group of at least two successive sheets in the panel have their warps and wefts in alignment with one another but angularly displaced and therefore out of alignment with the warps and wefts of the preceding group of at least two sheets. This second group of at least two sheets is then followed by another (or third) group of at least two more ballistic resistant sheets with their warps and wefts in the weaves of the individual ones of the ballistic resistant sheets in alignment with one another but angularly displaced from the warps and wefts of the immediately preceding or second group of at least two sheets. This pattern would continue throughout panel


14


. This construction, similarly to the above described alignment of warps and wefts of alternating sheets arrangement, can include the alignment of warps and wefts of the sheets within alternating groups of at least two sheets with, each adjacent group of at least two sheets having their warps and wefts angularly displaced and therefore out of alignment to the warps and wefts of the adjacent group of at least two sheets.




As seen in

FIGS. 2

,


3


and


8


, multiple sheets


47


, as seen in

FIG. 11

, are secured together with stitches


68


. Stitches


68


will penetrate through all sheets


47


of panel


14


. As discussed earlier for bar tac stitches


18


and


20


, the selection of fibers for stitching


68


will likewise vary in composition such as PBO, aramid and ultra high molecular weight polyethylene with deniers varying from 200 to 1500.




Stitches


68


are positioned into a pattern on and through layers


66


across panel


14


. Stitches


68


have rows of stitches aligned in one direction and rows of stitches aligned in another crossing direction to form a quilt pattern as seen in

FIGS. 2

,


3


and


8


. Stitches


68


are stitched to be approximately four to ten stitches to an inch. Other patterns are contemplated to be selectively used, such as a box pattern in which stitches


68
