Abstract

The present invention relates to a motorcycle helmet device for ventilation and shock mitigation. In summer, many safety helmets are not worn, for which reason Sturrofoam, a cushioning protection material installed inside the helmet, is composed of an insulating material, and the space inside the helmet is As a result, the external air flow is blocked because it is in close contact. In conventional helmets, the gap between the protective material and the endothelium is usually pressed by the head and the gap is narrowed, so that the effect of the air flowing into the through hole is insignificant. In view of the fact that the helmet shell (1) is formed in the upper side of the helmet shell (3; 6), respectively, the inner shell of the helmet shell (1) is a rubber bump (8) of 15-20mm height The dome-shaped protective material (7) is formed on the inner surface in a certain arrangement to enhance the cushioning effect, and the through-hole (4) and the discharge hole (5) are also secured in the protective material (7) at the through hole (4) and the discharge hole (5). Distribution of air flow By dissipating heat from the inside of the helmet to the outside effectively, the gap between the endothelial, which is an air distribution gap, and the protective material is always maintained at a constant level even by the hair. .

Description

Motorcycle helmet for ventilation and shock mitigation {AUTOBICYCLE HELMET SYSTEM FOR VENTILATION & COLLISION MITIGATION}

The present invention relates to a motorcycle helmet device for ventilation and shock mitigation. In the conventional motorcycle helmet device, as a protective device for protecting the driver's head in the event of an external impact, the helmet shell is made of synthetic resin, and the inside is a protective material such as styrofoam. It is made of inner skin of non-woven fabric, and it is essential for motorcycle driver's head protection equipment, especially in summer, when there are many non-safety helmet wearers. This is due to the phenomenon that the space inside the helmet is in close contact with the head of the head and the outside air flow is blocked.

For this purpose, it is proposed in the design of Korean Utility Model Publication No. 90-7910, which forms through and exhaust holes on the front and rear sides of the helmet shell, and attempts to dissipate heat by introducing external air into the protective material and the inner shell. The gap between the protective material and the endothelium is usually pressed by the hair, and the gap is narrowed, resulting in inefficient air circulation, and the effect thereof is insignificant.

Therefore, the present invention, in view of the above problems, proposes a new configuration as a cushioning material to protect the driver's head from external shocks, and smooths the flow of air flow inside the helmet to the outside heat dissipated from the inside of the helmet to the outside. It is to provide a motorcycle helmet device for ventilation and shock alleviation, which is effective in dissipating and keeping the gap between the endothelial, which is the air distribution gap, and the protective material at all times.

One embodiment configuration and operation of the present invention for achieving the above object will be described by the accompanying drawings.

1 to 4, in the helmet shell (1) formed with a see-through window (2), a through hole (4) and a discharge hole (5) formed on the front and rear sides, the through hole (4) and discharge An army-shaped sunshade (3; 6) is formed on the upper side of the helmet shell (1) where the ball (5) is formed, and the rubber protrusion (8) having a height of 15 to 20 mm is inscribed as an inner portion of the helmet shell (1). By forming a dome-shaped protective material (7) in a predetermined arrangement on the surface to secure the through hole (4) and the discharge hole (5) in the protective material (7) of the through hole (4) and the discharge hole (5).

As the action of the present invention configured as described above, as shown in Figures 1 to 3 by the Amish-shaped sunshade (3; 6), in the summer rainy season, the external rainwater through the hole (4) or the discharge hole (5) In addition to the awning that prevents the inflow, the Amish-shaped sunshade (3) formed on the front side also serves to assist the inflow of air into the helmet by forming a vortex of the wind in the dome of the helmet shell (1). have.

On the other hand, the protective material (7) in which the rubber protrusion (8) having a height of 15 to 20 mm is formed on the inner surface of the helmet shell (1) in a predetermined arrangement on the inner surface, is extruded from a soft silicone material, and the impact relief action is performed. Even if (9) is covered, the flow of air introduced between each array of rubber protrusions 8 formed at a height of 15 to 20 mm between the inner shell 9 and the helmet shell 1 is always ensured.

By adopting the A-shaped sunshade (3; 6), the summer rainy season has the effect of preventing external rainwater from entering the through-hole (4) or the discharge hole (5), especially the Ami formed on the front side The shape shade 3 has an effect of forming a strong vortex in the dome-shaped portion of the helmet shell 1 to facilitate the inflow of air into the helmet.

Meanwhile, the inner skin 9 is formed by a protective material 7 in which a rubber protrusion 8 having a height of 15 to 20 mm is domed in a predetermined arrangement on the inner surface of the helmet shell 1 extruded from a soft silicon material. Even if it is covered, since the space between the inner shell 9 and the helmet shell 1 is formed between 15 and 20 mm, the air flow due to the hair is not blocked, and the flow of air introduced between the arrays of the rubber protrusions 8 is smooth. It is very effective in cooling the heat inside the helmet.

In addition, the protective material (7) formed of soft silicon material is more flexible and resilient than the Styrofoam, the workability and impact relaxation between the helmet inner shell (1) is also very excellent, reducing the cost and helmet functionality of the product is also effective There is a useful design.
