Description

Foldable helmet

The present invention relates to a helmet, and more particularly, to a folding helmet that can protect the head in the event of a disaster such as leisure sports or an earthquake while considering lightness, portability, or shape deformation by using a flexible material.

In general, a helmet is worn to prevent injuries during leisure activities such as riding a motorcycle, inline skating, or horseback riding. Such a helmet should not only efficiently absorb impact when the helmet collides with the ground or other objects, but also minimize damage to the helmet due to impact.

A helmet outer shell manufactured to maintain the basic shape of the helmet and to have appropriate shock absorption so that it is not transmitted to the wearer by absorbing it when an impact is applied is located on the outer side of the helmet. In addition, a helmet inner shell that relieves the impact of the outer shell is located below it and is composed of a helmet shell, and a liner, etc. is attached to the inside of the helmet shell to improve wearing comfort when in contact with the wearer's head.

In order to satisfy the requirements as described above, the helmet shell must have adequate shock absorption to the extent that it can maintain its original shape without being deformed even by impact, whereas if it is too rigid, it may break during a collision, so it has a toughness (toughness) must also have. In addition, in order to improve the wearing comfort, it is necessary to satisfy the requirement that the specific gravity is small.

Until now, most helmet shells have been manufactured with fiber-reinforced plastics to satisfy the above requirements, and fiber-reinforced plastics include thermosetting resins such as unsaturated polyesters and epoxy resins, and fibers such as glass fibers, carbon fibers, and aramid fibers. It is a material that satisfies the above requirements to some extent because it is easy to process and can be manufactured relatively thinly while having high strength and shock absorption.

However, the reality is that fiber-reinforced plastics basically use a thermosetting resin and thus lack toughness compared to thermoplastic resins. Since the thickness has to be increased, not only the manufacturing cost increases, but also there is a problem that leads to a decrease in the fit due to the increase in weight.

In order to solve this problem, a helmet outer shell was manufactured using a thermoplastic resin. These fiber-reinforced plastics have a resin matrix as the basis, and in order to supplement their physical properties, various organic and inorganic fibers or non-woven fabrics, knitted fabrics, etc. are completely embedded in the resin structure. A recent technological trend is to form a resin structure with a minimum thickness based on such a resin structure, and additionally form lightweight materials such as fibers, knitted fabrics, and foam materials on one or both surfaces.

However, in this prior art, it is possible to achieve some weight reduction of the helmet as an inner shell formed of a porous foamed plastic layer and an outer shell formed of a compressed fiber sheet, but by using an outer shell having a standard shape, portability or shape It is difficult to secure deformability.

embodiment movement

Hereinafter, the operation of the preferred embodiment will be described in detail with reference to the accompanying drawings. First, a folding process in the unfolded state of the folding helmet 100 as shown in FIG. 2 will be described. At the same time as the rear member 130 is bent, the side members 120 on both sides are also bent at the same time to gather in the back of the head region of the wearer.

At this time, as the outer surface part 110 is bent, the airbag 118 starts to inflate, and the air valve 119 starts to close gradually in proportion to this. And, when the outer surface portion 110 maintains a round shape like a helmet, the air valve 118 is closed to act as a buffer against external impact.

Next, the position is fixed by hanging the side hole 125 with the back band 135 . By adjusting the length of the back band 135, the degree of adhesion of the head 30 can be adjusted.

Then, it is worn on the wearer's head 30 and fixed with a helmet strap 50 to complete the wearing. To convert the helmet shape back to the unfolded shape, the above-described method may be performed in the reverse order.

If the wearer collides while driving the bicycle and falls, the alarm unit 300 operates as follows. First, the gyro sensor 390 and the impact sensor 380 detect this and transmit a detection signal to the controller 310 .

The control unit 310 determines the detection signal and determines that the signal is greater than or equal to the reference value as an accident. Thereafter, the display 400 flashes red, the speaker 360 outputs a warning sound, and the communication unit 330 connects to a predetermined contact information (eg, 119 control center) to transmit a predetermined phrase or information.

In addition, when the wearer overspeeds on a bicycle, the gyro sensor 390 or the GPS sensor detects this. In addition, the controller 310 may operate the vibration sensor 370 to give the wearer a sense of alertness.
