Definitions
- the present invention generally relates to clothing or equipment for protecting people against shooting, and in particular the design of bullet-proof vests or other ballistic screens to have well-defined protection characteristics. It also aims to protect against penetrating weapons (punches, knives, ice picks, etc.).
- penetrating weapons punches, knives, ice picks, etc.
- a block of Plastiline® which is a paste of standardized hardness, and more particularly a block of Plastiline® with a weight of 80 kg maintained at a temperature of 20 ° Celsius or equivalent Fahrenheit.
- the equipment to be tested (specimen) is fixed on this block using straps, and a shot is made in the test tube at a determined distance (usually 5 meters for handguns and 10 meters for weapons called shoulder), this shooting being carried out using a shooting bench firing bullets of normalized weight at a speed also normalized.
- the equipment tested must fulfill two conditions:
- this depth parameter may vary according to the wishes of the client.
- the reproducibility of the tests is far from guaranteed, in particular because the properties of the Plastiline® block are likely to change significantly from one shot to another (in particular because the impact of a ball raises the temperature, softening Plastiline®, making it more prone to widening on the next impact). It can also happen that the environmental conditions of the test laboratory (temperature, etc.) can evolve during a shooting sequence, again modifying the properties of Plastiline®.
- Another disadvantage of this known test method is that it is unable to restore any result in terms of energy shock and vibration behind the equipment, and therefore no result in traumatic risk for the subject who will wear the equipment.
- 2007/138080 in the name of the Applicant, an equipment and a method for testing and designing protection equipment against blows. According to this patent application, one applies shots of energy well determined on a dummy equipped with protective equipment to be tested and instrument to determine impact energy for protection.
- the present invention therefore aims to overcome these limitations of the state of the art.
- a method for testing protective equipment with respect to piercing elements such as bullets or penetrating white weapons for the human being comprising the following steps:
- the manikin protection comprises a defined number of ballistic fiber sheets.
- step (c) is implemented in an initial phase of calibration of the protected dummy common to the testing of several protective equipment.
- an instrumented dummy for the testing of protective equipment with respect to piercing elements such as bales or perforating knives, the manikin comprising in at least one region to be exposed to piercing elements according to an energy and a kinematics determined a series of sensors, characterized in that it further comprises a manikin protection device placed in front of said region and designed to protect the manikin and the sensors against deterioration or destruction by the action of said perforating elements .
- a protective device for an instrumented dummy intended for the testing of protective equipment with respect to piercing elements such as bales or piercing white weapons for the human being. characterized in that it comprises a mechanical structure sufficiently attenuating the energy of the piercing elements to prevent the deterioration or destruction of the instrumented dummy under the action of said piercing elements provided for such a test.
- an assembly for testing a ballistic protection equipment characterized in that it comprises an instrumented dummy comprising in at least one region intended to be exposed to piercing elements such as bullets or perforating white weapons according to a determined energy and kinematics, a series of sensors, and at least two manikin protection devices each adapted to be placed in front of said region and designed respectively to protect the manikin and the sensors against deterioration or destruction under the action of perforating elements with kinematics and / or different energies.
- the application of piercing elements can be in particular a shooting of bullets or the displacement, with a speed and a determined force, of perforating white weapons (punch, knife, ice pick, etc.)
- the invention can also be applied to non-lethal bullet shooting such as rubber bullets.
- non-lethal bullet shooting such as rubber bullets.
- the protection of the manikin may be provided, or omitted. It may be the same for the test of low energy perforating knives.
- a mannequin M equipped in a manner known per se of a number of sensors C arranged in a test region, corresponding in particular to the thorax and the abdomen of the human body.
- These sensors are for example capable of measuring the following parameters:
- the manikin is equipped instrumented M of a manikin protection P which is permanently applied in front of the test region equipped with the sensors C.
- This manikin protection consists for example of a superposition of a fixed number of flexible sheets of ballistic fiber (typically Kevlar® sheets) of thickness also determined, the sheets being stacked and retained in an appropriate holding pocket, or a rigid shielding of a given thickness, for example a thick deforming shield made of polyethylene.
- a rigid shielding of a given thickness for example a thick deforming shield made of polyethylene.
- this dummy protection is designed by calculation and or experimentation so that, with the contemplated projectile energies, it provides sufficient protection for the instrumented dummy against any deterioration or destruction, by sufficiently attenuating these energies.
- This manikin protection remains permanently on the test region of the manikin for ballistic tests, but can advantageously be removed when for example it is desired to use the manikin for the test of protection against blows, in particular according to the patent application WO 2007 / 138080.
- the test of a protective equipment E such as a bulletproof vest in the present example is carried out according to the invention:
- the first series of measurements can be collected either immediately before the equipment test or during an initial phase of calibration of the manikin equipped with the protection P, in which case the first measurements are calibration for later use for different equipment tests.
- the second series of measurements is then processed in relation to the first series of measurements, using an appropriate calculator, to derive the effect of protection actually provided by the equipment E in progress. test.
- the present invention it is possible to use a conventional manikin and its sensors in the continuity and without the risk of seeing them deteriorated or destroyed by a perforating shot, while using a test procedure much more rigorous than that implemented for example according to the NIJ standard and allowing for the first time to translate the results recorded during a shot at trauma data for the subject using the protective equipment.
- the ballistic protection equipment that can be tested according to the present invention, in particular for homologation purposes, is very diverse. This may include clothing (bulletproof vests, etc.), removable accessories (bulletproof shields, etc.), bullet-proof cases, etc.
- the term "manikin” refers to any block of material of any shape, but of a diverence and a density of the same order of magnitude as those of the human being.
- a flexible manikin protection consisting of a stack of Kevlar®
- a polyethylene rigid dummy protection of appropriate thickness to avoid any risk of perforation.
