Definitions

• This application provides a unique construction of Anti-ballistic Chairs. More particularly, the core of these anti-ballistic chairs will consist of layers of flexible anti- ballistic fabric (soft armor) wrapped in two directions around the tubular members of the back rest, seat and skirt section, and alternatively, the anti-ballistic chairs will be constructed of pre-manufactured hard anti-ballistic armor components (hard armor).
• soft armor flexible anti- ballistic fabric
• hard armor pre-manufactured hard anti-ballistic armor components
• Bulletproofing is the process of making something capable of stopping a bullet or similar high velocity projectiles e.g. shrapnel.
• the term bullet resistance is often preferred because few, if any, practical materials provide complete protection against all types of bullets, or multiple hits in the same location.
• Bullet designs vary widely, not only according to the particular firearm used (e.g. a 9x1 mm Parabellum caliber hollowpoint handgun cartridge will have inferior penetration power compared to a 7.62x39mm assault rifle cartridge), but also within individual cartridge designs.
• Bullet-resistant materials also called ballistic materials or, equivalently, anti- ballistic materials
• ballistic materials are usually rigid, but may be supple. They may be complex, such as KEVLAR®, LEXAN®, and carbon fiber composite materials, or they may be basic and simple, such as steel or titanium. Bullet resistant materials are often used in law enforcement and military applications, to protect personnel from death or serious injuries.
• Anti-ballistic Chairs The principal advantage of Anti-ballistic Chairs is to supply conventionally appearing chairs that have the capability of offering anti-ballistic protection.
• Anti-ballistic Chairs Another advantage of Anti-ballistic Chairs is to supply chairs that people can crouch behind in a defensive position.
• Anti-ballistic Chairs Another advantage of Anti-ballistic Chairs is to supply chairs that can be relatively inexpensive to manufacture.
• Anti-ballistic Chairs fabricated of a variety of materials including multiple layers of soft fabric woven from an aramid fiber together, which is sold by Du Pont under the registered trademark KEVLAR® and will resist and absorb the impact of a bullet.
• Another advantage is to supply Anti-ballistic Chairs fabricated of multiple layers of resin impregnated fabric of aramid fiber creating a hard anti-ballistic material that will resist and absorb the impact of a bullet.
• Anti-ballistic folding chairs are that they can be easily transported and stacked.
• Anti-ballistic folding chairs are that they can be held up by one or both hands in more mobile defensive positions.
• a further advantage is to create Anti-ballistic Chairs that have been uniquely designed so that they may be manufactured in a factory that specializes in employing blind workers.
• the preferred embodiment of the Anti-ballistic Chair will consist of a conventionally appearing stacking chair with padded seat cushion and back rest with a tubular framework with arm rests. The addition of a protective skirt section below the seat will extend to the floor level.
• the anti-ballistic core of the chair will consist of layers of fabric woven from an aramid fiber, which is sold by Du Pont under the Trade Mark KEVLAR® wrapped in two directions around the tubular members of the back rest, seat and skirt section.
• the anti-ballistic core portions of the Anti-Ballistic Chairs may be fabricated using not only Aramid fibers and EVLAR® from DuPont, but also polyethylene fibers and GOLD SHIELD®, which is a KEVLAR® based material, and SPECTRA SHIELD®, which is polyethylene based material, both available commercially from Honeywell.
• GOLD SHIELD® and SPECTRA SHIELD® are high strength synthetic fibers impregnated in partially cured resin for use in ballistic material.
• both of the Honeywell materials can be used as layered soft armor as well as hard armor when they are autoclaved or compression molded into anti-ballistic components for construction of the Anti-Ballistic Chairs.
• Other similar materials of like purpose and function are also anticipated by this disclosure.
• the first alternate embodiment of the Anti-ballistic Chair will be a folding chair constructed of a tubular framework with hard anti-ballistic surfaces on the seat and lower skirt section with the back rest conventionally padded, having soft woven anti-ballistic fabric, or having the hard anti-ballistic surface.
• Two soft handles or two hard handles will be on either side of the seat so that when the chair is folded it may be held up in a defensive or offensive position.
• the second alternate embodiment of the Anti-ballistic Chair will additionally be a folding chair constructed of a tubular framework that has the ability of having the hard anti-ballistic surface or the layers of fabric woven from an aramid fiber wrapped around the tubular members. Two soft handles or two hard handles will also be on either side of the seat of this chair so that when the chair is folded it may be held up in a defensive or offensive position.
