Description

 Description Automatic gas inflatable head shock absorber Technical field

 The present invention is intended to provide an automatic gas inflatable head with excellent freedom of use when not in use and a sense of release as a protective device for passengers such as motorcycles, a fall protection device for workers at high places, and a moving device. A start-up key that is simultaneously provided by a ring-shaped expansion chamber case that has a double expansion chamber made of transparent material that acts as a shock-absorbing mechanism during operation, and a flexible gas line that injects gas into the expansion chamber in the case. It is related to the function as a shock absorber and the detachment function after inflation. By adding a separate starting device and a part of gas cylinder to this, it operates as an automatic gas inflation type head shock absorber. Background art

 Conventionally, helmets, known as motorcycle and other passenger protection equipment, fall protection equipment for high-altitude workers, exercise equipment, etc., have existed as effective equipment for protecting the occupant's head. However, the present invention, like the JPO Utility Model Registration No. 304804, operates using physical phenomena in an emergency as a triggering factor, and concentrates the head and neck. There is no equipment that has the function of the present invention as a protective device. In addition, the starting device and the starting key in the present invention basically refer to JPO Utility Model Registration No. 3 069 811.

The effectiveness of helmets in protecting heads of passengers, workers and athletes in the event of a motorcycle accident, a high-level worker falling accident, or a crash during sports is a clear advance. However, on the other hand, Due to loss of sensation, loss of visual field, difficulty in wearing, discomfort in the hot weather, and the tendency to dislike the discomfort caused by wearing helmets on the hair, which has recently become a prominent trend. There is a fact that the effective helmet cannot be applied properly.

 Also, as a religious precept, people who wear turbans and the like on their heads cannot, in the first place, wear existing helmets.

 Under the condition that the starting device and a part of the gas cylinder can be fixedly mounted within the effective range as a separate body, the passenger can use it daily on a daily basis when it is not operating. A device that has a shock-mitigating effect is mounted in a simple manner, and simultaneous use with a conventional helmet is more effective if a shock to the user's neck is taken into account.

 Regarding the characteristic shape of the present invention, the ring-shaped inflatable chamber case is compact when not in operation to secure the mobility and freedom unique to passengers such as motorcycles, high-altitude workers, and athletes. In addition to having a shape, the starting device and the gas cylinder part are separately provided, so that it is lightweight and contributes to improving the user's balance.

 Regarding the operation, the flexible gas line for gas injection has a function as a starting key and a detachment function after inflation at the same time. Gas injection, expansion chamber expansion, starting device and release operation from a part of carbon dioxide gas cylinder are designed to work sequentially, contrary to the will of motorcycle riders, aerial workers, athletes, etc. A simple physical mechanism and operation respond to possible accidents and disasters by trying to eliminate the cause of malfunction.

In addition, the transparent inflatable air chamber of the transparent material, which is folded and stored in the ring-shaped inflatable air chamber case of the present invention, is designed to respond to impact without excessively compressing the head during inflation. Injecting atmospheric pressure into the inner chamber from the check valve In addition, the bellows mechanism, which forms the inner wall of the inner chamber, controls the direction of expansion of the expansion chamber and controls the shape of the expansion chamber at the same time. In addition, the double expansion inflatable chamber made of transparent material, which is folded and stored in the ring-shaped expansion chamber case of the present invention, is an outer chamber that expands by gas injection. Two-stage buffer using the internal pressure of the internal chamber and the external chamber generated from the difference between the injected gas pressure and the atmospheric pressure by the two chambers, the inner chamber that expands due to the suction of the air and the air, and the check valve. By having a structure that becomes a device, the effect of canceling out the impact wavelength is generated, and an effective impact mitigation ability is to be obtained. Disclosure of the invention

 When the automatic gas inflatable head impact mitigation device of the present invention expands a double-layer inflatable chamber made of a transparent material, the actuation key integrated with the flexible gas line activates the carbon dioxide gas cylinder. Since the seal is broken, the gas passes through the flexible gas line and is injected into the outer chamber of the expansion chamber through the backflow prevention valve. When the chamber expands and at the same time the inner chamber, which shares the wall with the outer chamber wall, rises, the air is drawn from the backflow prevention valve for the inner chamber and expanded to use the difference in internal pressure generated in the inner chamber and the outer chamber. The two-stage shock absorber provides effective shock mitigation capacity

The inner chamber described above expands in the vertical direction while being regulated in the circumferential direction by a bellows mechanism provided on the inner chamber wall, and requires a head due to the internal pressure of the inhaled atmospheric pressure even at the end of gas injection. It is possible to obtain the impact mitigation ability corresponding to the impact without pressure.

The ring-shaped inflation chamber case and the flexible gas line integral with the inflation chamber have a cable penetrating through the flexible gas line. An activation key is provided at the end of the cable, and the flexible gas line branches off from the cable just before the end of the cable and connects to the activation device via the disconnecting device. Both detaching devices have a structure that can be detached separately.

 The starting key and release device on the flexible gas line configured in this way are used for vehicles and building structures in the event of a traffic accident such as a two-wheeled vehicle, a fall accident at a high place, or a crash in sports. A cable integrated with a flexible gas line due to a physical phenomenon in which a user wearing the present invention is detached against the will of the user from a starting device and a gas cylinder fixed to exercise equipment, etc. The start key that is present at one end of the inflator starts the actuation by falling off the actuation device, and the act of detaching the actuation device from the flexible gas line by the detachment device after the expansion chamber expansion. In the time difference created by the total length difference between the cable length and the maximum length of the flexible gas line, the starting device Gas Note human, expansion chamber expansion, activation device and gas cylinder - withdrawal operation than parts are those having rows divided structure.
