The panel's advanced design not only enhances protective capabilities but also facilitates practical deployment in real world scenarios.
In various embodiments, a ballistic system may comprise a cover, a headrest hood, an armor assembly and a backer. The cover may define an opening and form a pocket. The headrest hood may be operatively coupled to the cover. The headrest hood may be configured to be installed over a headrest of a vehicle. The armor assembly may be installable in the cover. The backer may be partially installable in the cover. The backer may include a protruding portion that extends out of the cover.
In various embodiments, the cover may be made of 1000 denier nylon. The cover may comprise a front and a back. The cover may include a mole array of the front of the cover. The back may contact a back of the vehicle seat in response to the ballistic seat backer being installed in the vehicle. The cover may be sized such that it provides ballistic coverage for the headrest of the vehicle. The cover may have a top curved portion
In various embodiments, the headrest hood may be made of a 4 way stretch nylon material. The backer may be a rigid backer or a semi rigid backer (e.g., plastic). The protruding portion of the backer may be sized to install in a rear pocket of a vehicle seat.

Any one of the stitch consolidated assemblies of plies for soft body armor assembly described herein is achieved using any stitching thread and any type of stitching method to achieve through-thickness connectivity of the plies, including chain stitching or lock stitching to secure all plies in the assembly together.
To achieve a desired level of protection, soft body armor assemblies described herein are configured to inhibit the complete penetration of a particular ballistic threat by overcoming the energy associated with the ballistic event. Two examples of commercially available high strength fibers routinely used to generate anti-ballistic ply structures used in soft body armor assembly include para-aramid fiber, such as Kevlar® fiber from Dupont and Twaron® fiber from Teijin, and UHMWPE, including Spectra® fiber from Honeywell and Dyneema® fiber from DSM.
The performance of ballistic protective equipment utilizing ply structures generated from high strength fiber is generally measured based on penetration resistance, as well as the resistance to back face deformation that can lead to blunt trauma injuries. Penetration resistance is routinely reported as the VSO, which is defined as the velocity at which a specific ballistic threat will penetrate an armor construction 50% of the time. A methodology routinely used for determining the VSO of a particular armor system against a specific threat is outlined in Mil-STD 662F VSO Ballistic test for Armor and Purchase Description FQ/PD 07-0SG, Body Armor, Multiple Threat/Interceptor Improved Outer Tactical Vest (IOTV) Generation Ill. The methodology for determining back face deformation is outlined in NIJ Standard 0101.06, Ballistic Resistance of Body Armor. As will be understood from the comparative and experimental examples provided herein, the soft body armor assembly for soft body armor assembly 110 meets these standards and provides numerous advantages over monolithic and other hybrid designs. For example, soft body armor assembly 110 is comfortable, durable, flexible, lightweight, and provides increased performance, including resistance to ballistic penetration, back face deformation performance, resistance to mechanical fatigue, and resistance to fragmentation threat, and the like.
Woven fabrics generated using para-aramid fiber have long demonstrated robust ballistic performance as anti-ballistic ply structures used in flexible armor systems. Woven anti-ballistic fabrics rely on mechanical interlacing of yarns using commercial weaving equipment and are a desired when designing systems that provide flexibility, comfort, conformability, and improved breathability. Additionally, the mechanically interlocked woven fabrics are very durable, requiring no adhesives or matrix resins to create the ballistic ply structure. Woven anti-ballistic fabrics and can undergo significant flexural fatigue without losing ballistic performance. Several investigations of flexible body armor fabricated using woven para-aramid fabrics reclaimed after more than a decade of continuous use in the field have demonstrated no ballistic performance loss when compared to the performance of the same designs when first issued.
Unidirectional laminates represent a second type of anti-ballistic ply structure used in the manufacture of flexible body armor systems. Unidirectional laminates are constructed from two or more layers of unidirectionally oriented high strength yarns adhesively bound together using matrix resins and optionally polymer films. The unidirectional fiber layers in the unidirectional laminate are cross plied; having fiber direction of individual layers rotated 90 degrees relative to the neighboring layers they are laminated to. Unidirectional laminates have demonstrated improved ballistic VSO performance and improved back face deformation performance against high energy deformable projectiles such as bullet threats when compared to woven fabric systems for the same areal density. Disadvantages associated with the unidirectional laminate structure include reduced fragmentation threat resistance, increased stiffness and potentially reduced mechanical fatigue resistance when compared to woven structures generated with the same fiber.
Due to the aforementioned issue associated with its use in woven constructions, the unidirectional laminate was conventionally the preferred anti-ballistic structure for UHMWPE fiber. UHMWPE has found significant commercial success in soft armor systems when used in unidirectional laminate structures. These materials are commercially available under the trade names Spectra Shield® from Honeywell, or Dyneema® Unidirectional from DSM. These unidirectional laminate materials are generated using tacky adhesive matrix resins capable of overcoming the low surface friction and low surface energy of the UHMWPE fiber, resulting in mechanically stable anti-ballistic structures.
