DETAILED DESCRIPTION

FIGS. 1-3 depict an example multi-curve body armor plate 100 worn toward the front of a male torso 102. FIG. 4 depicts the example multi-curve body armor plate 100 worn on a female torso 104. Multi-curve body armor plate 100 has a ceramic strike face 106 having a first complex curvature that outwardly presents a convex surface to ballistic projectiles. The armor plate 100 is wearable on a front torso 102, 104 of a person having a protruding chest. The strike face 106 has a lower region 108 with a lower convex portion shaped to follow a cylindrical contour of an abdomen and chest of the torso 102, 104. An upper portion 110 of the strike face 106 laterally tapers to a top edge and curves backwardly to accommodate the protruding chest.

FIGS. 5-6 depicts an example multi-curve body armor plate 500 worn on the female torso 104. Multi-curve body armor plate 500 has a reduced height and a second complex curvature that corresponds closer to the female torso 104.

FIGS. 7-10 depict an exemplary multi-curve body armor plate 700 that conforms to the front contours of a human torso.

In one aspect of the present disclosure, a multi-curve body armor plate system provides:

(i) Horizontal axis curvature (X°) of from 8° to 22°; and (ii) Vertical axis curvature (Y°) of from 9° to 28°. In another aspect of the present disclosure, a multi-curve body armor plate system provides: (i) Horizontal axis curvature (X°) of from 12° to 22°; and (ii) Vertical axis curvature (Y°) of from 13° to 25°. In another aspect of the present disclosure, a multi-curve body armor plate system provides: (i) Horizontal axis curvature (X°) of from 14° to 16°; and(ii) Vertical axis curvature (Y°) of from 15° to 18°.

In another aspect of the present disclosure, a multi-curve body armor plate system provides for body armor plates having a horizontal axis curvature which approaches a curvature of at least 12°, 15°, 17°, or 20° along with a vertical axis curvature which approaches a curvature of at least 15°, 17°, 21°, or 24°, despite the fact that this would immediately facilitate the use of said armor plates by subjects with a need for such curvatures. In another aspect of the present disclosure, the plate is sized to fit a generally shorter and narrower female torso.

Ceramic materials of the plates can be made as disclosed in: (i) U.S. Pat. No. 10,234,243 to Ganor, entitled “Antiballistic armor comprising a super-hard strike face”; (ii) U.S. Pat. No. 10,215,537 to Ganor, entitled “Modular ceramic composite antiballistic armor”; and (iii) U.S. Pat. Publ. No. 20170275742 to Ganor, entitled “Ceramic and metal boron nitride nanotube composites” the disclosures of all of which are hereby incorporated in their entirety.

In one or more embodiments, the plate is not comprised of a ceramic material bonded to aramid or to an ultra-high molecular weight polyethylene fiber composite plate, instead it is comprised of solely of ultra-high molecular weight polyethylene fiber composite material; solely of steel or a metal alloy with comparable strength and toughness; of a high-hardness metal such as steel bonded to aramid or to ultra-high molecular weight polyethylene fiber composites; of a ceramic material bonded to a metal alloy; of a carbon-fiber or SiC-fiber reinforced ceramic article; of carbon fiber composite materials; of glass fiber composite materials; of basalt fiber composite materials; of a castable ballistic polymer; of a ceramic article encapsulated in aluminum or magnesium; or of aluminum.

FIG. 11 depicts a carrier system 1100 having an armor carrier 1102 with front and back panels 1104, 1106 for carrying armor plates. A shoulder harness 1108 connects the front and back panels. The shoulder harness providing a support surface that rests upon shoulders of a wearer. According to aspects of the present innovation, the front panel 1104 can hold a multi-curved body armor plate 100 (FIG. 1). The armor carrier 1102 incorporates what is effectively an integral sports-bra. If the standard plate carrier looks like a “plate carrier,” according to aspects of the present innovation the carrier system 1100 look like a “female plate carrier.” Carrier system 1100 has an extra adjustment mechanism and extra padding around the bust line, which is fairly strong and elastic to function as a sports bra. Side pouches can be included for optional side plates (not shown). With a strong and elastic adjustment mechanism around the bust line, the plate can be held close and tight against the upper torso. Tests conducted have shown that women wearing armor plates are significantly more comfortable if the plate is worn in this manner. The carrier system 1100 is built for plates with an enhanced curvature, but can accommodate standard multi-curve plates. The bust-line adjustment mechanism can be removed, unfastened, or loosened quickly. The bust-line adjustment mechanism is held in place either by Velcro, by a buckle, or by a rapid-release plastic fasteners.

A plate pocket 1110 is made of soft fabric, and is in some manifestations elastic, so the plate pocket 1110 will fit all plates within a certain size range, such as 7″×9″ to 10″×12″, and can accommodate various degrees of curvature. Given the exaggerated curvature of the new plate, along with the fact that it is being worn angled forward against the wearer's body to some extent, an elastic band around the bust of the wearer and that is behind the plate provides additional support and comfort. FIG. 12 is a graphical plot 1200 of illustrative dimensions of a plate pouch of the carrier system 1100.

FIG. 13 depicts a front panel of the carrier system 1100. Each of the front and back panels 1104, 1106 include an S-shaped gusset panel to provide a rain barrier. Un upper point of front and back flaps 1112 respectively of the front and back panels 1104, 1106 are higher the generally known carrier systems to accommodate an underarm cummerbund. For example, FIG. 14 depicts detachable direct elastic underarm and waist cummerbunds 1420, 1422 with a vertical link strap 1424 for the armor carrier 1102 the carrier system 1100 (FIG. 11).

The vertical link strap 1424 is separate attachable with vertical elastic of adjustable link strap could be introduced to make the upper strap (underarm cummerbund 1420) follow forward when reaching back for lower waist cummerbund to make easier to grab hold of end for fixing in place at front.

In one or more embodiments, the direct elastic underarm cummerbund 1420 uses 50 mm wide elastic.
