This disclosure relates to a universal insert compatible across protective vest platforms and a retrofit kit that is specific to a vest platform enabling quick release for a ballistic shield within the vest.
Description of the Related Art
A ballistic vest or bullet-resistant vest, often called a bulletproof vest or plate carrier, is an item of personal armor worn on the torso that helps absorb the impact and reduce or stop penetration to the body from firearm-fired projectiles. Soft armor vests are made of many layers of woven or laminated fibers and can protect the wearer from small-caliber handgun and shotgun projectiles. These vests often have a ballistic plate inserted into the vest. Metal or ceramic plates can be used with a soft vest, providing additional protection against rifle rounds.
Hard-plate reinforced vests are mainly worn by combat soldiers, police tactical units, and hostage rescue teams but are becoming increasingly popular also among civilian users. Hard-plate reinforced vests may include an exterior pocket that is sized to accommodate the hard plate and that protrudes from an outer face of the vest. If the wearer of the vest ends up in a body of water, the heavy ballistic plate(s) presents a serious buoyancy issue, requiring the wearer to immediately discard the vest or risk drowning. A major drawback with such an emergency decision is that the vest typically has numerous pockets for a variety of tools, survival gear and ammunition, so that jettisoning the vest saves the wearer's life but at a high cost.
There is thus a need for an improved protective vest.

DETAILED DESCRIPTION
A quick-release ballistic plate assembly for a protective vest includes an outer chassis configured to attach to a chest panel and/or back panel of the vest is disclosed. The outer chassis has an open lower end leading to an inner cavity, wherein a ballistic plate and sleeve subassembly inserts upward into the cavity. An emergency release handle depending downward from the subassembly may be pulled to overcome a retention mechanism and jettison the subassembly in case the wearer ends up in a body of water. This avoids the need to shed the entire protective vest which typically has numerous pockets for a variety of tools, survival gear and ammunition. The assembly may be built into the protective vest at the OEM level, or may be retrofit to existing vests.
A quick-release ballistic plate assembly for a protective vest, comprising an outer chassis having a pair of flexible flat panels connected together at outer top and side edges thereof, with aligned lower edges unconnected to define a lower mouth leading upward to an inner cavity between the panels, the outer chassis having attachment structure thereon for mounting to the protective vest. A ballistic plate and sleeve subassembly has a rigid ballistic plate held within a flat sleeve made of low friction polymer, and the subassembly is sized to fit through the open mouth of the outer chassis into the cavity. The subassembly has an emergency release handle centered on one end thereof. A subassembly retention mechanism has a release cable fixed to the emergency release handle that passes laterally outward through a plurality of flexible retention loops hanging down from the aligned lower edges of the outer chassis. Opposite lateral ends of the release cable are affixed to the outer chassis by safety ties or other retention device such as snaps having sufficient strength to retain the release cable in place against a weight of the subassembly while being configured to break from manual downward pulling on the emergency release handle.
Further advantages, features and details of the invention will be apparent from the following description, in which examples of embodiments of the invention are described in detail with reference to the drawings. In this context, the features mentioned in the claims and in the description may each be essential to the invention individually or in any combination.
FIG. 1A is a perspective view of a protective vest 20 outfitted with a quick-release ballistic plate assembly of the present application. The protective vest 20 is representative of a number of similar vests, and includes front chest and rear back panels 22a, 22b connected via side belts 24, and having a pair of shoulder straps 26 attached to outer faces and looping over the top of both panels. Although not shown, typical protective vests 20 of this nature feature a plurality of loops or pockets for containing ammunition, survival gear, or the like. This type of vest is often known in the industry as CMU-37 or CMU-38.
FIG. 1A shows, at the bottom end of both panels 22a, 22b, a lower end of a quick-release ballistic plate assembly 30. FIG. 1B shows a ballistic plate and sleeve subassembly 32 being separated from the vest 20. The assembly 30 includes an emergency release handle 34 at the lower end of a pull strap 36 attached (e.g., sewn) to the exterior of the plate and sleeve subassembly 32. Pulling down on the emergency release handle 34 rapidly releases the subassembly 32 which, by virtue of its weight and slight manual pull assistance, drops straight down, thus separating it from the vest 20. Pulling down on the release handle 34 pulls free a release cable 38 that retains the plate and sleeve subassembly 32 within the vest 20.
FIG. 2 is an elevational view of the quick-release ballistic plate assembly 30, and FIG. 3 is a similar view with an outer chassis 40 shown in phantom to visualize the inner ballistic plate and sleeve subassembly 32. The outer chassis 40 comprises a generally rectangular flat unit formed of front and rear flexible (e.g., fabric) panels 42 connected together at their top and side edges 44. The bottom edges 46 of the panels 42 are left unconnected so as to form an open lower mouth therebetween that leads upward into a cavity between the panels. The outer chassis 40 may be made of panels of 1000D water repellent, flame-retardant nylon (MIL-DTL-32439 Type I, Class 4), which is a tough, pliable material used extensively in aircrew vests and other flight gear, and is a proven petroleum, oil, lubricant (POL) and flame-resistant material suitable for naval aviation use.
After the plate and sleeve subassembly 32 is placed within the inner cavity of the outer chassis 40 through the lower mouth, a retention mechanism 50 described below supports the weight of the subassembly 32 from falling out. The emergency release handle 34 projects downward below the lower edges 46 for easy grasping.
FIG. 3 shows the retention mechanism 50 which includes the aforementioned release cable 38 fixedly attached to the emergency release handle 34 or pull strap 36. Pull strap 36 is affixed to the plate sleeve via stitching, adhesive, or other method. The release cable 38 extends laterally outward in both directions from the central release handle 34 and passes through a series of retention loops 52 attached to the lower edges 46 of the chassis panels 42. The release cable 38 is then secured at its outer ends to the chassis 40. More specifically, the release cable 38 has holes 39 (see FIG. 4C) at each outer end through which safety ties 54 or an alternative retention device (e.g., snaps) pass. Safety ties 54, in turn, loop through the eyelets 56 extending through both panels 42 of the chassis 40. The safety ties 54 may be configured similar to zip ties, with a ratchet-type tightening mechanism. The safety ties 54 or other retention device are configured to have a nominal strength which retains the release cable 38 in the position illustrated in FIG. 3, but which is relatively easy to break upon yanking the emergency release handle 34 downward. More particularly, the safety ties 54 have sufficient strength to retain the release cable 38 in place against a weight of the subassembly 32 while being configured to break from manual downward pulling on the emergency release handle 34. Reference is made to FIG. 1B showing the plate and sleeve subassembly 32 falling out of the chassis 40 (fastened to the inside of front chest panel 22a).
FIGS. 4A-4F are perspective views of a lower end of the outer chassis 40 illustrating several steps in assembling the inner ballistic plate and sleeve subassembly 32 therewith. The outer chassis 40 is shown inserted into an interior pocket formed by the front chest panel 22a of the protective vest 20, though as will be seen below the chassis 40 could also be attached to an inner wall of the chest.
In a first step of assembly, in FIG. 4A, the plate and sleeve subassembly 32 is inserted within the inner cavity of the chassis 40. With the subassembly 32 mostly inserted, the assembler threads the release cable 38 sequentially outward through the retention loops 52a, 52b on both sides of the release handle 34, as in FIG. 4B. The retention loops 52a, 52b on the opposite lower edges 46 of the chassis 40 are interlaced such that the release cable 38 passes through loops on alternating edges until it is in the position shown in FIG. 4C.
With reference to FIGS. 4C and 4D, a safety tie 54 is then inserted through the hole 39 at the end of the release cable 38, and through the eyelet 56 at the lower corner of the chassis 40. Once the safety tie 54 has been closed, as in FIG. 4E, the plate sleeve subassembly 32 is secured within the chassis 40. FIG. 4F shows an optional step of trimming the free end of the safety tie 54.
FIG. 5 is an elevational view of a rear face of the quick-release ballistic plate assembly 30. The assembly 30 may be provided with a larger pocket 70 into which a soft armor protective plate 72 can be inserted and secured with overlapping panels. Soft plates 72 made of tough material such as Kevlar are often used when a rigid ballistic plate is not necessary or in conjunction to further enhance ballistic protection.
FIG. 6 is an elevational view of a ballistic plate sleeve 80 having a lower end 82 opened up. The plate sleeve 80 has an enlarged loose closure flap 84 with one component of a hook and loop fastening patch thereon which meets with the other component in the form of a strip 86 on the exterior of the sleeve. The closure flap 84 has a larger longitudinal dimension than the strip 86 so that the flap may mate with the strip in a variety of positions. This arrangement enables the closure flap 84 to fasten in a variety of configurations in order to conform to different sizes of rigid ballistic plate.
FIGS. 7A/7B, 8A/8B and 9A/9B are elevational views of different ballistic plate and sleeve 80 combinations that can be formed for use in the modified protective vests disclosed herein. As seen in FIGS. 7A, 8A and 9A, ballistic plates come in different sizes and shapes. When inserted within the sleeve 80, the closure flap 84 can be mated in different ways with the hook and loop strip 86 as seen in FIGS. 7B, 8B and 9B.
The plate and sleeve subassembly 32 may be easily expelled from within the chassis 40. First of all, the wearer need only yank on the lower emergency release handle 34 to break the safety ties 54 and pull the subassembly 32 of the chassis 40. Additionally, the sleeve 80 of the subassembly 32 may be made of an extremely low friction polymeric material which facilitates removal of the subassembly from within the chassis 40. One suitable material is an ultrahigh molecular weight polyethylene (UHMWPE) woven composite. One example is sold under the tradename Dyneema, and has an exceptionally slick surface that minimizes friction when removing the subassembly 32 from sometimes highly compressed protective vests.
FIG. 10 is a lower end view of the assembled outer chassis 40 and inner ballistic plate and sleeve showing the retention mechanism having the release cable 38 passed through a plurality of the fabric retention loops 52a, 52b. This illustrates the passage of the release cable 38 through alternating loops 52 on opposite lower edges 46. FIG. 11A is a schematic diagram indicating the mechanical forces imparted to the retention mechanism in use. That is, the weight of the plate and sleeve subassembly 32 imparts alternating mechanical forces on the release cable 38 which tend to balance one another out, thus putting minimal stress on the safety ties 54 (or other retention device) at each end. More particularly, the downward forces imparted by the weight of the subassembly 32 on the alternating retention loops 52a, 52b translates into both downward and front-to-rear oriented forces on the loops, which strain the release cable 38 in a serpentine manner. This helps retain the release cable 38 in place and reduces the magnitude of lateral force that reaches the safety ties 54. Consequently, the safety ties 54 can be made relatively lightweight to make breaking them easier, while they are still sufficiently strong to maintain their integrity for extended periods. The safety ties 54 may be made of plastic, such as materials compatible with the anticipated environmental contaminants (nylon or ethylene chlorotrifluoroethylene (ECTFE) beaded safety ties). In the illustrated embodiment there are four retention loops 52a, 52b on opposite lower edges 46, two on each side, which is believed to be a minimum suitable number to provide adequate holding force.
FIG. 11B is a diagram indicating forces acting on the release cable 38 of the retention mechanism during actuation. Namely, the only forces acting laterally are the reaction forces Ftie from pulling on the safety ties 54, as well as minimal frictional forces Ffriction imparted by the retention loops 52a, 52b on the cable 38. This reduces the amount of force needed to pull the release cable 38 from within the retention mechanism 50, thus releasing the plate and sleeve subassembly 32 to be pulled free or drop from the chassis 40. Moreover, the release cable 38 may be made of polytetrafluoroethylene (PTFE or Teflon) which has low friction, is capable of withstanding large surface normal forces, has a wide service temperature range, does not embrittle or age, and is flame resistant, making it an excellent candidate for naval aviation environments.
FIG. 12 is an elevational view illustrating one way to mount a quick-release ballistic plate assembly 30 to a chest panel 22a (or back panel 22b) of a protective vest shown in phantom. The ballistic plate assembly 30 has a pair of buckle straps 90 or other such interlocking load bearing elements secured thereto at upper lateral corners. Mating buckle straps 92 are added to the rear face of the chest panel 22a near upper lateral corners as well. These can easily be added at the OEM level or retrofitted to existing protective vests with stitching. The mating buckle straps 90, 92 support the majority of the weight of the assembly 30 including the ballistic plate therein. A lower hook and loop strip 94 on a front face of the assembly 30 engages a mating hook and loop strip (96 in FIG. 15) on the rear face of chest panel 22a. Again, such a mating hook and loop strip is easily stitched to the chest panel 22a. Thus, simply adding two buckle straps 92 and a strip of hook and loop fastener to each chest panel 22a, 22b retrofits the protective vest 20 to receive front and rear quick-release ballistic plate assemblies 30.
FIG. 13A is a perspective view of an alternative modified protective vest 100 outfitted with a quick-release ballistic plate assembly 30 of the present application. This type of vest is often known in the industry as PRU-70. FIG. 13B shows the ballistic plate and sleeve subassembly 32 being separated from the vest in the same manner as above; by pulling down on the emergency release handle 34 to break the safety ties 54.
FIG. 14 is perspective view from a lower perspective of the alternative protective vest 100 of FIG. 13A showing one way to retrofit a quick release ballistic plate assembly 30 therewith. Namely, this type of vest includes an interior cavity opening downward and bordered by two lower edges 102. The assembly 30 is inserted upward into the cavity and held therein by buckles, fasteners, or the like.
FIG. 15 is a schematic diagram of the retrofitting process for two exemplary types of protective vests 20, 100. The combination of the plate/sleeve subassembly 32 into the chassis 40 to form the quick-release ballistic plate assembly 30 is the same, regardless of vest type. From there, installation of the hook tape, anchors and replacement panel (if needed) changes depending on the vest type. Templates are utilized to guide retrofit fabrication. An anchor placement template 120 locates the mating buckles/straps 122 within the cavity that are configured to mate with the buckles 90 on the exterior of the chassis 40. An outer stitching position template 124 is then held in stable position on the exterior of the vest 100 to guide the technician as to where to sew the buckles/straps 122 within the cavity. The outer stitching position template 124 can then be removed, as it may be paper, while the anchor placement template 120 may remain in place or be ripped out as well, as it does not impede attachment of the ballistic plate assembly 30.
