BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to the field of military applications and more specifically to the field of blunt force trauma protection systems for military personnel.
Background of the Invention
There is an increasing need for added protection for gunners and other personnel in gun turrets of military vehicles. Improvised explosive devices and other methods for attacking military vehicles have drawn added interest in the safety of gunners. Conventional methods for protecting gunners include reliance on the outer armor of the gun turret. Drawbacks to such conventional methods include instances in which force from the explosive devices enters the interior of the military vehicle or impacts against the side of the vehicle, or instances in which maneuvering of the vehicle to avoid a blast or other related obstacles may place the gunner at severe risk of injury or death. For instance, the blunt force trauma from contact of the gunner against the sides of the gun turret may place the gunner at such risk.
Methods have been developed to overcome such drawbacks. For instance, reactive armor on the outside of the military vehicle and body armor worn by the gunner have been developed. Drawbacks to such developments also include risk of injury or death when the explosive forces enter the interior of the gun turret.
Consequently, there is a need for improved methods for protecting gunners in gun turrets of military vehicles from explosive forces.

In some embodiments, blanket 10 has stitching 300 substantially around the perimeter of blanket 10. Without limitation, stitching 300 protects protective padding 75 against fluids by not allowing such fluids into the interior of blanket 10.
Protective padding 75 may include any type of padding suitable for protecting the personnel against blunt force trauma from contact with a part of the vehicle (i.e., a part of the protected firing platform 20). In embodiments, protective padding 75 is an energy mitigation padding. The energy mitigation padding may be any type of padding suitable for attenuating and/or absorbing energy (i.e., energy from contact force). It is to be understood that attenuating energy refers to reducing the strength of energy. It is also to be understood that absorbing energy refers to the padding absorbing energy. In an embodiment, the energy mitigation padding is energy attenuating padding. The energy attenuating padding may be any padding suitable for attenuating energy. In an embodiment, the energy attenuating padding is energy attenuation foam, honeycomb structures, visco-elastic material, or any combinations thereof. The energy attenuation foam may include any foam that attenuates energy. In an embodiment, the energy attenuation foam includes polymeric foam. Any suitable polymeric foam that attenuates energy may be used. Without limitation, examples of suitable polymeric foams include polyethylene foam, polyurethane foam, or any combinations thereof. In some embodiments, the energy attenuation foam includes metallic foam. Any metallic foam suitable for energy attenuation may be used.

In embodiments, the energy mitigation padding is energy absorption padding. In an embodiment, the energy absorption padding is polymeric foam.
In embodiments, the energy mitigation padding has layers of different impact protection. In some embodiments, energy mitigation padding has a high velocity impact protection layer (i.e., configured for forces from a vehicle roll-over or blast event) and a low velocity impact protection layer (i.e., configured for forces from vibrations of the vehicle or from typical movement of the vehicle). The high velocity impact protection layer may provide protection against any high velocity contact of the personnel against protected firing platform 20, and the low velocity impact protection layer may provide protection against any low velocity contact of the personnel against protected firing platform 20. The high velocity impact protection layer may include contact of the personnel against protected firing platform 20 between about 100 ft/s and about 6,000 ft/s, and alternatively between about 50 ft/s and about 6,000 ft/s. The low velocity impact protection layer may include contact of the personnel against protected firing platform 20 between about 1 ft/s and about 50 ft/s, alternatively between about less than 1 ft/s to about more than 0 ft/s. In embodiments, the material for each of the layers may be different to provide the low velocity impact protection layer and the high velocity impact protection layer. In other embodiments in which protective padding 75 is foam padding, the densities of the foam padding of the high velocity impact protection layer and the low velocity impact protection layer may be different to provide the desired impact resistances. For instance, embodiments may include the low velocity impact protection layer having a lower density than the high velocity impact protection layer. Without limitation, the energy mitigation padding may reduce accelerative injuries due to vehicle turnovers and the like. Further, without limitation, the energy mitigation padding may not have a significant reduction in impact resistance due to repeated routine contact with personnel and/or devices (i.e., weapons, etc.).
