Field of the Invention The present invention relates to a shock absorbing method for absorbing a shock when worn during a work or a work that may cause a fall accident such as a motorcycle operation, riding a horse, and working at a height, and protecting a fallen person's body. The present invention relates to clothing with an airbag for use.

[0002]

2. Description of the Related Art In an act or work such as driving a motorcycle, riding a horse, or working at a height, there is a fear that a fall may cause a strong impact on a human body, resulting in injury or death. For this reason, for example, the use of a lifeline has been obligatory for work at height, for example. In general, when driving or riding a motorcycle, protector wear such as a rider suit and jockey wear is worn to protect the body from impact such as falling.

[0003]

However, in the former case, since the work cannot be performed outside the length of the lifeline, it is necessary to move the ligature during the work, and at this moment, it is possible to avoid being unprotected from a fall accident. Had the problem of not being able to do so.

[0004] In addition, the latter has a structure in which a shock absorbing block of urethane foam resin or the like is attached along the wear in most cases. To enhance safety, it is necessary to make the shock absorbing block as thick as possible. Improvements have been desired because the structure impairs the mobility of the wearer.

The present invention has been made in view of the above-mentioned problems, and is worn in an act or work that may be subject to a strong impact on the human body due to a fall accident, such as an operation such as motorcycle driving or horse riding or working at a high place. At the time, it is housed in the clothes so that it does not disturb the work and operation of the wearer, and in the event of a fall accident, it is instantaneously activated and the compressed gas cylinder attached to the clothes before colliding with the ground or It is an object of the present invention to provide a shock-absorbing garment with a shock-absorbing airbag that expands in a balloon shape around the garment by the action of gunpowder or the like and has a cushioning effect of absorbing shock to reduce the effects on the body such as bruises. It is assumed that.

[0006]

A wear with an air bag for shock absorption according to the present invention comprises a wear main body worn on at least a part of a body, and at least a part of the wear main body, and has a relatively outer surface side. One or more airbag accommodating pockets forming a fragile portion line structure that can be crushed by weak tension and accommodated in each of the airbag accommodating pockets, and the volume when inflated is sufficiently larger than the capacity of the airbag accommodating pocket. An airbag made of a flexible sheet material, an accident detecting means for detecting a fall of a wearer of the wear body, and a high-pressure gas which is communicated with the airbag and rapidly pressurizes the inner cavity of the airbag by the accident detecting means. And a high-pressure gas generating means for generating or supplying air. When the wearer falls from a high place, the airbag is inflated into a balloon shape before landing. It is an gist to buffer the collision of the body.
