    [0004] FIELD OF THE INVENTION
    [0006] The present invention relates generally to the field of helmets. More specifically, the present invention provides a novel helmet for full contact sports and medical use, more specifically, for soccer, flag football, rugby, full contact fighting sports, for conditions such as autism, epilepsy, and chronic traumatic encephalopathy. The present invention provides a novel helmet with features that increase shock absorption and reduce the risks of head and brain injury. Also, the present invention further relates to the manufacturing method of the novel helmet.
    [0008] BACKGROUND OF THE INVENTION
    [0010] People who play sports are at risk of injury. In full contact fighting sports, i.e. taekwondo, there is a risk of head and brain injuries due to the impact caused by a punch, kick or fall, which could lead to a concussion. A concussion occurs when an impact to the head is severe enough to cause brain injury due to the brain hitting the hard walls of the skull or the sudden change in acceleration and deceleration forces.
    [0012] According to a document titled "Effects of taekwondo kicks on head acceleration and injury potential" by Fife, O'Sullivan, Pieter & Kamisnki, the US Centers for Disease Control and Prevention (CDC) have rated concussions sports-related as a "silent epidemic" with 1.5 million traumatic brain injuries and 300,000 concussions in the United States annually. The full contact fighting sport of taekwondo, with more than 80 million participants worldwide, has concussion incidence rates ranging from 5.5 to 50.2 per 1,000 athlete exposures, nearly four times higher than reported in American football. For the Therefore, it is necessary to improve the characteristics of the protective helmet to reduce the effects of an impact on the head.
    [0014] In order to reduce the likelihood of having a concussion, many tests have been developed to determine parameters that provide information on the effects of a head impact and determine limits to reduce risks. At present, the most widely used parameters to evaluate brain injuries and prevent them are linear acceleration, rotational acceleration, and the criteria for head trauma.
    [0016] The document entitled "Biomechanics of the head for Olympic Boxer Punches" by TJ Waliko, DC Viano, CA Bir, illustrates the effects of linear acceleration and rotational acceleration. To explain these effects, Figure 1 shows a boxer's punch applying a force to a test head. In Figure 1, the horizontal axis represents the direction of the balance of forces. The boxer's fist applies a force to the test head. At the same time, a shear force is applied to the neck in the direction opposite to the force of the fist. Due to these forces, the test head is under a linear acceleration and a rotational acceleration. Linear acceleration is the acceleration from the center of mass towards any linear direction according to the sum of forces The acceleration of rotation is the acceleration that causes the head to rotate relative to the center of mass.
    [0018] On the other hand, in 1961 the Gadd Severity Index (GSI) was proposed. To determine the Severity Index (SI), an impact is represented in a rectangular coordinate system, where the X axis corresponds to the impact period and the Y axis represents the acceleration of the head. Taking into account the above, the SI is calculated by integrating the curve. Therefore, a relatively long duration low acceleration impact could give the same GSI value as a short duration high acceleration impact. Because of this, several objections were raised against this criterion.
    [0020] As a result, Versace developed a new criterion in 1971, called the Head Injury Criterion (HIC). The HIC addresses the deficiencies of the SI, providing comparable head injury tolerance values regardless of the curve. The HIC considers the most damaging part of the impact, peak and near peak sections, and excludes less damaging sections, thus providing a more precise level of head injury tolerance. The HIC is defined as:
    [0024] To determine the tolerances of the human head, in the documents "State of art Human Tolerance" by Synder and "Injury and Skeletal Biomechanics" by Goswani it is proposed that the limits can be established using two criteria: Linear acceleration and HIC. Based on these criteria, the following tolerances were proposed:
    [0036] These limits are probabilistic, that is, the closer to the lower limit, the probability is low and increases until reaching 100% (upper limit). To understand this, FIG. 2 shows an extension of Table 2 above, where the real probability of injury is shown. Furthermore, FIG. 3 shows the correlation between the AIS (Abbreviated Injury Scale) and deaths.
    [0038] Taking these criteria into account, the inventors of the present application determined the head velocity, head acceleration and HIC when the head is impacted due to a kick or fall shown in TABLE 3. To determine head velocity, head acceleration, and the HIC when the head is kicked, the inventors relied on the disclosure of the paper "Effects of Taekwondo Kicks to the Head" by Gabriel P Fife, et. Alabama. For the head's velocity, its acceleration, and the HIC when the head is impacted by a fall, the inventors calculated these values from kinematic analysis.
    [0045] Furthermore, according to the document entitled "Biomechanics of the head for Olympic Boxer Punches" by Waliko et al, the fist produces the values shown in TABLE 4. when it hits the head:
    [0049]
    [0052] As can be seen, the data above shows that it is necessary to provide the proper equipment that reduces HIC and head acceleration to reduce the likelihood of a head injury. For this, many helmets have been developed, which are designed to absorb the impact caused by a kick, a punch or a fall.
    [0053] An example is US Patent No. 4,706,305 to Soo S. Cho, which describes a helmet made of polyurethane foam, which is a conformable and elastic material that is capable of absorbing energy when it comes into contact and deforms with a hit. The helmet protects the forehead, the back of the head and the sides of the head and includes ear protectors.
    [0055] Another example is XU Xiaohu's Utility Model No. CN 204395396 U, which discloses a head protection body made of polyurethane that incorporates reinforcing sheets and elastic bands, where the reinforcing sheets are placed at the bottom. of the protective helmet to reinforce the connection section, so that the helmet better absorbs the energy of the external impact.
    [0057] However, when the helmet receives an impact, there are both low-frequency and high-frequency impacts. Helmets disclosed by US Patent No. 4,706,305 and Utility Model No. CN 204395396 U can absorb shock, but their performance in absorbing high-frequency shock is poor.
    [0059] Siklosi US Patent Application No. 2014/0090153 A1 discloses a helmet comprising a plurality of plates that can be attached and removed by adjustable straps, each of the plates comprises an inner layer, an outer layer and a plate trauma between the inner and outer layers. The inner and outer layers are made of a strong material such as ethylene vinyl acetate (EVA). The trauma plate comprises a rigid material capable of dispersing on impact such as rigid plastic.
    [0061] In US Patent No. 5,177,815 to Andujar, they specify a protective helmet constructed of an elastic foam base element, namely polyvinyl chloride and a plurality of pad elements made of foam of harder composition, namely EVA. The pad members are secured to the upper surface of the base member.
    [0063] Although the helmets described by Siklosi and Andujar provide another layer of material to provide additional protection for the wearer, ethylene vinyl acetate is not sufficient to attenuate or reduce high frequency impacts. In addition, members of the helmet disclosed by Siklosi are removable. This can result in movement or detachment of the helmet members, causing the wrestlers to need to take time to rearrange the helmet, which is undesirable for spectators who are enjoying the match. On the other hand, the helmet disclosed by Andujar has the disadvantage that the pads easily detach from the base member.
    [0065] Therefore, there is a need to provide a helmet capable of attenuating both low-frequency and high-frequency impacts to reduce the likelihood of concussion and to provide an optimal fit to keep helmet parts in place after use. take a hit.
    [0067] In accordance with the current ASTM F1446-15b Standard Test Methods for Equipment and Procedures Used in Evaluating the Performance Characteristics of Protective Helmets and the ASTM F2397-04a Standard Specification for Protective Helmets Used in Martial Arts in the Test of freefall:
    [0068] • An impact velocity of 3.0 ± 0.15 [m / s] will report an acceleration measurement that cannot exceed 100-G
    [0069] • A velocity impact of 4.0 ± 0.2 [m / s] will report an acceleration measurement that cannot exceed 300-G
