Description

Helmet Device with Airbag {A Helmet Appratus with Air Bag}

The present invention relates to a helmet device, and more particularly, a helmet with a built-in airbag that has a head protection function to absorb a shock applied to the head in case of a collision, and is provided with a protective airbag surrounding the head. Relates to a device.

The present invention relates to a head protection helmet device worn by a driver when driving a motorcycle or a racing car, the conventional general helmet is made of a hiber in the outside to reduce the impact, the inside is composed of a styropole liner and cloth It is common. Therefore, the gap between the head and the helmet was large, and in many cases, a large portion of the impact applied to the helmet was directly transmitted to the brain, resulting in brain damage.

Helmets originate from medieval knights using metal plates and protective gears covering their heads, mouths, ears and noses with metal or leather or cloth, and are commonly used to prevent accidents when building, drilling or riding motorcycles. Recently, made of synthetic resin is also spread, and it will be called essential equipment provided for the safety of firefighters, policemen, and sports athletes.

In general, the conventional helmet is made of a hard fiber on the outside, and the inside of the cushioning material of the foam resin. Such a conventional helmet has a large gap between the inner shell and the head, and in the case of an accident caused by driving a motorcycle or a racing car at a high speed, the impact caused by the accident is absorbed to some extent from the outer shell and the inner shell. The parts are delivered directly to the brain, which often leads to brain damage.

Therefore, the present invention was devised to solve the above problems, forming an air bag between the inside of the helmet and the head, wearing the helmet in the air removed from the air pocket, after wearing the helmet again air Blow into the air bag so that there is no gap between the helmet inner shell and the head so that the air bag is swelled tightly to the head.In case of an accident, the shock is absorbed by the air bag. It is an object to provide a helmet device with a built-in air pocket.

Helmet device with a built-in air bag according to the present invention for achieving the above object and the outer shell to primarily protect the external shock; An inner shell located inside the outer shell to secondarily absorb an external impact; An air pocket positioned inside the endothelium and fixed to one side by being attached to the endothelium and the other side to be in close contact with the head by adjusting air pressure from the outside to absorb shocks during a collision; An air valve for maintaining a constant air pressure in the air bag through intake or exhaust; And an air pump that allows air to be sucked in or exhausted from the air bag through the air valve.

In addition, the air valve of the helmet device with a built-in air bag according to the present invention is an intake air valve for maintaining the air pressure of the air bag in the intake state when the air bag is intake; When exhausting from the air bag is made of an exhaust air valve to maintain the air pressure of the air bag in an exhausted state,

In addition, the intake air valve of the air valve of the helmet device with a built-in air bag according to the present invention is an intake diaphragm that prevents the intake air is out during intake and the exhausted air when exhausted back into the air bag again An intake coke is provided to prevent inflow, and the exhaust air valve includes an exhaust diaphragm that prevents exhausted air from entering the exhaust air and an exhaust coke which prevents intaken air from leaking out of the air bag again. It is made, including.

As described above, the helmet device with the built-in air bag according to the present invention has an air bag inside the helmet, while maintaining the air layer at a predetermined interval between the driver's head and the helmet inner shell, the air bag and the head are in close contact with each other. In addition, the airbag absorbs the shock during driving accidents, thereby significantly reducing the impact on the brain, thereby minimizing brain damage that may occur due to an accident.

Hereinafter, a preferred embodiment of a helmet device with an air bag according to the present invention will be described in detail with reference to the accompanying drawings. The following examples are merely illustrated to illustrate the present invention, and are not intended to limit the scope of the present invention.

Shown are installed air pumps and switches and air tubes.

Referring to FIG. 1, the helmet is made of fiber, and the outer shell 101 primarily absorbs external shocks, and the inner shell 103 made of cork, styropol, etc., secondaryly absorbs shocks. And one side is attached to the inside of the endothelial and one surface is in close contact with the head to absorb the shock and the air valve 109 and the air valve 109 for adjusting the pressure to the internal air of the air bag 107 It consists of an intake cock 111 and the exhaust cock 113 and the like to lock or open the air intake or exhaust air bag 107, one side of the air valve 109 is connected to the air bag 107 The other side is connected to the air pump 507 via an air tube 115.

2 is a cross-sectional view of the air valve, the right side is an exhaust valve and the left side is an intake valve. The intake valve is composed of an intake diaphragm 201a, an intake coke 111a, an intake coke outer body 203a, and the like. Etc., the intake diaphragm 201a and the exhaust diaphragm 201b are attached to the intake and exhaust holes on the diaphragm partition 207, respectively, so that air flows in only one direction. When the helmet is worn, the helmet is worn while the air is removed from the air bag 107. After the helmet is worn, the air pump is locked by turning the intake cock 111a to open the intake valve and turning the exhaust cock 111b to lock the exhaust valve. 507 to blow air into the air bag 107 so that the air bag 107 is in close contact with the head.When the helmet is taken off, the intake cock 111a is turned to lock the intake valve, and the exhaust cock 111b is turned to exhaust the air bag 107. With the valve open, the air bag 107 is exhausted by the air pump 507 to allow the air bag 107 to crumble, and then the helmet is removed.

4A and 4B, a coke air hole 401 is formed in the coke 111, and the coke 111 is inserted into the coke hole 403 of FIG. 4B. Therefore, when the air hole 401 of the cock and the air hole 301 of the cock outer body 203 match each other, as shown in FIG. 3, the air passes through the valve, and when the holes do not match with each other, the flow of air is blocked. .

Referring to FIG. 5, an air pump 507 is provided outside the helmet to intake or exhaust air into the air bag 107. At the time of intake, the intake switch 503 is turned on and the exhaust switch 505 is provided. To turn off the air pump 507 is operated in the forward direction to intake air into the air bag 107, when exhausting the exhaust switch 505 On and off the intake switch 503, the air pump 507 Is operated in the reverse direction to exhaust the air from the air bag (107).

FIG. 6 illustrates an embodiment in which an air pump 507 and an air pump switch 501 are attached to a motorcycle, and an air tube 115 is connected to a helmet.
