A PCC according to some embodiments of the invention, may also include a pair of gloves 124. Each glove may include a fastening strap 126 for firmly holding the glove about the wrist of the soldier wearing the gloves 124.
Trousers 106 may comprise of a pelvis portion 109 and two pant legs 132. Trousers 106 may include a belt 107. Trousers 106 may include pockets, e.g., pockets 134, 150, at various positions. For example, hip pocket 134 may include a top opening covered by top cover 138. Hip pocket 134 may also include a side opening 136, which may be opened or closed using a zipper 137 that is provided across the side opening 136.
The trousers 106 may be made of textile/s that are stab or slash resistant.
Trousers 106 may include venting openings 128. The soldier may keep the venting openings 128 closed or opened, by employing a zipper (shown is the zipper puller 130). By opening the venting openings, the soldier may facilitate air flow through the trousers so as to cool the soldier's body. In some embodiments the venting openings 128 may be positioned across the thighs, one at each of the thighs, as illustrated in Fig. 1. Other design arrangements of the venting openings may also be employed.
On each leg pant 132 a knee pad pocket 140 may be provided. Similarly to the elbow pad pockets, the knee pad pockets 140 may be located at the anticipated position of the knee of the soldier who is to wear the trousers 106. Each knee pad pocket 140 is designed to receive a knee pad.
Each knee pocket 140 has an opening (e.g. a bottom opening 144, through which the knee pad may be inserted into the pocket. A fastener, e.g. hook-and-loop fastener 148 is placed across opening 144, so that the knee pad may be inserted and the pocket opening 144 is then sealed by the fastener 148.
In order to facilitate appropriate positioning of the knee pad against the knee of the soldier wearing the trousers, the knee pad pocket is designed so as to allow repositioning of the knee pad within the pocket.
An elongated strap 146 of a hook-and-loop fastener extends inwardly on the inside surface of pocket 140, so that the knee pad may be properly positioned adjacent to the knee of the soldier, and secured in position, by attaching the matching patch 412 of the hook-and-loop fastener (see Fig. 4B) to corresponding strap 146. This ensures that the soldier may rearrange the knee pad inside knee pad pocket 140 to lay at a proper and convenient position. Strap 142 (e.g., comprising two cooperating fastener straps 142a and 142b) may be used to fasten the pant leg and secure the knee pad in its proper position against the soldier's knee.
Fig. 3 is a front view of an infantry soldier wearing protective combat clothing, according to some embodiments of the present invention, with open venting openings.
Venting opening 128 (this may apply to any venting opening provided on the PCC) may include a zipper across the opening (show is the zipper puller 130) for opening or closing the venting opening. Net (e.g., mesh) 302, with holes of predetermined size, may be placed over the opening to allow ventilation and prevent entry of dirt, bugs, etc. through the net 302.
Fig. 4A is a rear view of a knee (or elbow) pad 400, according to some embodiments of the present invention.
Fig. 4B is a front view of a knee (or elbow) pad 400, according to some embodiments of the present invention.
Fig. 4C is an exploded view of a knee (or elbow) pad 400, according to some embodiments of the present invention.
Pad 400 may be designed as a three-layered article.
Top protection layer 404 may be impact-distribution layer 404, which is aimed at distributing an impact on the knee, when kneeling or otherwise. This layer may be made, for example, from a laminate of polypropylene and aramide, and is aimed at distributing an incoming impact over the layer so as to reduce the pressure imparted by the impact on the knee and minimize any risk of damage.
Second protection later 403 (see Fig. 4C) may be a puncture-resistant layer, which may be made, for example from aramide. This layer is design to prevent, or greatly reduce the possibility of a sharp object, such as, for example, a blade, a nail, broken glass, etc. from penetrating the pad and injuring the soldier's knee, when kneeling down.
A third cushioning layer 402 - which is designed to face the knee or elbow, serves as a cushioning layer, to cushion the knee, when placed on the ground, when the soldier kneels, or when coming in contact with or hit by a rigid object (e.g., wall, stone, metal object, etc.). The third layer may be made, for example, from ethylene-vinyl acetate (EVA), polyethylene foam, etc.
Fig. 4D illustrates bending compliance of a knee or elbow pad, according to some embodiments of the present invention.
The elbow or knee pad, according to some embodiments of the present invention are designed to dynamically change from a generally flat orientation, along the elongated axis of the leg or arm, when placed over a straightened knee or elbow, to a bent orientation, when the knee or elbow bend, in compliance with the bending of that limb. At the same time, the pad is designed to present a curvature that is orthogonal to and extending along the longitudinal axis of the limb, so as to conform to the curvature of the limb.
Thus, according to some embodiments, the pad has a substantially fixed curvature 414 orthogonally to the elongated axis 415. The cushioning layer may be provided with two substantially opposite indentations 410, which define an axis extending between these indentations, about which the pad may bend. A groove 408 in the cushion padding 406 may enhance this bending axis, as the padding is likely to more readily yield along the groove 408 in response to bending force applied on the pad.
The second puncture resistant layer is typically rather thin and possess some flexibility, that allows it to bend easily with the bending of the third cushioning layer.
The first, impact distribution layer, is typically hard and not as flexible as the other two layers. Furthermore, because of its curvature extending along the elongated axis, it may be hard to bend it about the bending axis 413, which is substantially orthogonal (right angle 418) to the elongated axis 415. To address this problem the first puncture-resistant layer 404 may be comprised of two parts 404a and 404b, which partially overlap. The two parts may be stitched together along stitch line 407, so that the edge 409 of part 404b, which is over part 404a, is free - not secured to part 404a. Thus, when the pad is bent in conjunction with bending of the knee or elbow, a bend curvature 416 of the pad may be obtained.
Fig. 5A is a front view of a PCC underwear 500, according to some embodiments of the invention.
Fig. 5B is a back view of a PCC underwear 500, according to some embodiments of the invention.
Underwear 500 may be made as a complete piece of clothing 502, from for example, UHMWPE knit fabric, for enhanced protection against shrapnel and/or ricochets. A rubber band 504 may be provided for holding the underwear about the waist and/or thighs of the wearer. Preferably, Lycra threads may be incorporated into the UHMWPE knit fabric for added flexibility and comfort.
