- the assembly of the invention comprises an extensible and retractable mechanism with a shock-absorbing effect, fixed on the rear part of a high hardness steel, aluminum or titanium plate.
- the retractable mechanism comprises a metallic and/or polymeric spring element attached to a central axis of support on the metallic plate or behind the anti-splinter panel according to the concept of vehicle construction.
- the retractable mechanism comprises a configuration, in addition to fixing the anti-splinter panel well on the metal structure, it helps to transform the kinetic energy of the projectile, piercing the metal plate, into energy absorbed by the retractable shock-absorbing element fixed on the structured sandwich panel, increasing the absorption and dissipation of the energy of the projectile and/or the punch detaching itself from the metal plate.
- the present invention has the objective of offering a ballistic protection solution with greater ballistic resistance to bullet impacts and explosion fragments, for use mainly in armored personnel carriers, military, security, police, valuables and VIP vehicles.
- the objective of the present invention is to provide an increase in the ballistic resistance capacity of the anti-splinter panel, composed of woven and non-woven fabrics with natural, synthetic, polymeric and/or mineral fibers; which is fixed with a retractable damping mechanism on the structured panel.
- the elongation / deformation of the anti-splinter panel allows it to absorb the energy of the projectile and/or a metal fragment that has become detached from the front plate.
- the ballistic resistance of the anti-splinter panel is increased by the ability to move backwards thanks to the retractable shock-absorbing mechanism.
- the present invention refers to an assembly of plates with different materials (sandwich panel) that makes up a ballistic panel structured in combination with a retractable (double-acting) shock-absorbing mechanism that allows the anti-splinter panel (spall liner) to carry out a limited movement backwards, pushed by a projectile that pierced the front plate in steel and/or aluminum.
- a panel assembly that comprises a compressible member mechanism (spring) attached to a central support axis, which completely crosses the ballistic panel to transform the kinetic energy of the projectile into energy absorbed in the first part by the momentary recoil movement of the anti-splinter panel and secondly, by the elongation/deformation capacity with or without perforation of some layers of fabrics of the same anti-splinter panel (spall liner). This makes it possible to better stop, absorb and dissipate the residual energy of the projectile.
- spring compressible member mechanism

- the current problem is the creation of lighter protection systems mainly for military personnel carriers, to protect them against armor-piercing projectiles and fragments of explosions with a substantial reduction in the total weight of the vehicle with the purpose of increasing its versatility and autonomy and survival in operation.
- the initial solution was the use of high hardness steel plates, generally 450/500 brinell).
- this solution is cumbersome, limiting the good mobility of the vehicle in operations.
- Ballistic panel applied spring systems are known in the art. An example of this is referenced in pepka pct application WO2014149087, which describes a shield assembly including a panel, a base plate and a spring coupled between the shield panel and the base plate.
- This development is aimed at absorbing an impact or projectile blast that will hit the armor assembly and deflect the armor panel and spring.
- the spring and armor panel absorb enough energy from the impact or projectile blast to prevent damage to underlying structures.
- the spring may be solid having a desired coefficient to protect against a given impact load. This development only defines a layout configuration between the shield panel and the base plate.
- the current technique even when it shows shock-absorbing mechanisms fixed on the ballistic panels composed of steel and/or aluminum plates, has not established an effective configuration that includes the addition of an anti-splinter panel (spall liner) structured with woven fabrics and non-woven with natural, synthetic, polymeric and/or mineral fibers, increasing resistance thanks to the movement capacity of a part of the surface of the anti-splinter panel (spall liner) behind a very high hardness metal plate perforated by any type of projectile, fixed with a retractable mechanism that forms the body, doors, under the chassis and roof of any type of vehicle that increases the ability to resist projectiles, metal fragments from landmine explosions and artillery bombs, perforating the external metal plate, increasing the survival of the personnel inside any type of vehicle.
