Definitions

  • the present invention relates to a helmet comprising an outer shell made of hard material and a shock-absorbing liner arranged inside the outer shell.
  • a helmet for safety such as an open face type or a full face type is conventionally known as a helmet worn by riders such as motorcycles to protect their heads.
  • a conventional helmet mainly comprises an outer cap body, an impact absorbing liner, a pair of left and right pistols disposed inside the cap body, and an interior pad for improving the wearing comfort of the wearer. It consists of Also, in order to secure the visibility of the wearer, a through hole for ventilation is provided at the top of the opening window provided on the front of the helmet.
  • this cap serves to disperse the impact over a wider area and to absorb impact energy by its deformation.
  • the shock absorbing liner absorbs the impact energy transmitted from the outer cap by absorbing the impact energy by reducing its thickness (i.e., compression) and delaying the propagation of the impact energy to the head of the wearer. By doing this, it acts to reduce the maximum acceleration due to the impact.
  • maximum acceleration means the maximum value of the acceleration obtained by the "impact absorption test" of the helmet.
  • impact absorption test In order to confirm the protective performance of safety helmets, "impact absorption test” has been conducted conventionally.
  • a metal head model is used as a model of the head of the helmet wearer.
  • the shock applied to the helmet by the “shock absorption test” is absorbed as described above, and finally the acceleration transmitted to the head is the acceleration placed inside the metallic head model
  • the maximum acceleration is measured by the meter.
  • the method of such “impact absorption test” and the reference value of the maximum acceleration are respectively defined in each country.
  • the helmet has a substantially spherical shape, the rigidity of the top of the head is necessarily greater than that of other parts, making it difficult to absorb an impact. Therefore, a structure called an insert liner was invented.
  • a cavity is provided on the inner top of the impact absorbing liner, and another member is inserted therein.
  • the inserted member (referred to as an insert liner) has a smaller density, ie, is softer than the impact absorbing liner, so the rigidity of the crown can be reduced. In this way, it is possible to maintain the shock absorption of the top of the head.
  • Diffuse axonal injury means that the brain is strongly shaken, resulting in rupture of the brain's axons and the onset of injury.
  • the mechanism by which diffuse axonal injury occurs in the rider's head is described as follows.
  • the impact acceleration (this is referred to as translational acceleration) generated by such an external force acting in the vertical direction is measured in the “shock absorption test”.
  • the conventional insert liner structure has mainly dealt with the translational acceleration of the impact.
  • the helmet when an impact is applied to the upper part of the helmet and near the top of the head, the helmet tries to rotate to the left around the center of gravity because the impact point is above the center of gravity of the helmet.
  • the impact generates a force for rotating the helmet, that is, rotational acceleration.
  • the lower end of the helmet hits the neck of the wearer, or the friction between the helmet and the road surface stops the rotation of the helmet.
  • the rotational acceleration due to the impact is transmitted to the head of the wearer.
  • the wearer fastens the pike, the wearer's head will also stop rotating at the same time as the helmet.
  • the rotational acceleration is transmitted to the inside of the wearer's head, in the skull, the rotational force acts on the brain floating in the brain, and the axon connecting the brain and the inside of the skull is torn.
  • the helmet according to the first aspect is a helmet comprising an outer cap body made of a hard material and a shock absorbing liner disposed inside the cap body, the shock absorbing liner comprising a body liner and the body liner A recess provided on the inner surface, an insert liner fitted in the recess, and a central support member disposed between the bottom of the recess and the bottom of the insert liner.
  • the impact applied to the outer cap body is absorbed by deformation of the impact absorbing liner disposed inside the outer cap body.
  • an insert liner is fitted in the recess of the main body liner.
  • the center strut member is compressed and deformed by the impact, and the insert liner is inclined. That is, the insert liner moves relative to the main body liner.
  • rotational acceleration does not propagate inside the head.
  • a space exists in addition to the insert liner and the central support member. That is, the same effect as the conventional insert liner can be obtained by reducing the volume instead of reducing the density as in the conventional insert liner. In this way, not only the rotational acceleration of the wearer's head, but also the translational acceleration can be effectively reduced.
  • the helmet of the second aspect is the helmet of the first aspect, wherein the shock absorbing liner comprises a plurality of other support members disposed around the central support member.
  • the support members together with the central support member even if the wearer's head squeezes the insert liner when the wearer fastens. Since it supports the insert liner, it can be worn in a stable state without the insert liner being inclined and the helmet being shaken.
  • the helmet of the third aspect is the helmet of the first aspect or the second aspect, wherein the central support member is integrally formed with the insert liner.
  • the helmet of the third aspect by forming the central support member integrally with the insert liner, it is possible to suppress an increase in the number of components of the helmet.
  • the helmet of the fourth aspect is the helmet according to the second aspect or the third aspect, wherein the cross-sectional area of the tip of the other strut member is smaller than the cross-sectional area of the tip of the central strut member, and the center
  • the post member and the other post members are integrally formed with the insert liner.
  • an increase in the number of components of the helmet can be suppressed by integrally forming the central support member and the other support members with the insert liner. Also, when an impact force is transmitted from the bottom of the recess to the central support member and the other support members, the other support members having a smaller contact area are deformed or broken earlier, so the central support member Can be completely destroyed by impact. In this manner, the insert liner can be reliably inclined by the central support member.
  • the recess in the helmet according to any one of the first to fourth aspects, includes an air passage in communication with the air inlet in front of the helmet and an air passage in communication with the air outlet in back of the helmet.
  • a passage is provided, and the insert liner is provided with an air passage connecting the recess and the inner surface of the main body liner (the surface in contact with the head of the wearer).
  • the outside air taken in from the air inlet on the front of the helmet is led to the recess of the main body liner and further from the recess to the rear air outlet.
  • the flow of air causes hot air emitted from the head of the wearer to be directed from the inner surface of the main body liner to the recess through the air passage of the insert liner. Also, the air from the recess enters the inner side surface of the main body liner. In this way, ventilation in the helmet can be performed well.
  • the helmet of the sixth aspect is the helmet according to the fifth aspect, wherein the air inlet is an edge wrap member of the opening on the front surface of the helmet.
  • the air inlet is used as the edge winding member of the opening on the front face of the helmet, so that the number of steps for providing the air inlet penetrating the cap can be eliminated, and It is possible to suppress an increase in the number of component parts.
