It relates to a folding helmet that is easy to assemble or disassemble into a flat form.

In general, a helmet is a hat worn to protect the head from impact. Helmets are mainly worn on the head for the safety of users when riding a bicycle or doing leisure sports such as ATV, skiing, rafting, skating, rollerblading, rock climbing, and climbing. Recently, it is essential to wear a helmet for safety even when riding an electric kickboard.

However, although wearing a helmet is very important for safety, most of the helmets are fixed in a semicircular shape so that they can be worn directly on the head. Accordingly, since the volume is very large, it is very inconvenient to carry and store the helmet.

In order to solve such inconvenience, recently, a foldable helmet that can be carried by minimizing the volume of the helmet is preferred. The foldable helmet can reduce the volume, and it is important to secure safety, which is a unique function of the helmet.

In this regard, in Korean Patent Application Laid-Open No. 10-2010-0060458, the helmet shell is foldable, and an airbag endothelium that expands to fit the shape of the wearer's head when air is injected into the helmet shell is excellent in shock absorption, A multifunctional helmet that is convenient to store and carry by folding the helmet is known.

However, since the divided skin is folded and unfolded in a state of maintaining an arc shape similar to the size of a helmet, there is a problem that it is still bulky to carry and store.
