Technical Field:
[0001] The present invention relates to an improved multi-layer safety helmet that protects
the head by dispersing the impact energy of an external impact to prevent the impact
energy from being transferred to the head when a user wears the helmet on the head
and is lightweight and well ventilated.
Background Art:
[0002] Users of bicycles and motorcycles are required to wear helmets. In the case of a
conventional helmet, it has been pointed out that there is a limit in protecting a
user because a buffer material has one layer.
[0003] Accordingly, the inventor of the present invention has developed an improved multi-layer
safety helmet according to the present invention that consists of two or more layers
of a buffer material and forms a buffer space between the layers such that the outermost
layer absorbs the impact in order to minimize the transfer of impact to an inner layer.

- a lower buffer portion 100 worn on the user's head; and
- an upper buffer portion 200 coupled to an upper portion of the lower buffer portion
100,
wherein an impact applied from the outside is firstly absorbed by the upper buffer

[0014] Moreover, a frame 300 is integrally coupled to the lower buffer portion 100.
[0015] A frame 400 is integrally coupled to the upper buffer portion 200.
[0016] In addition, a lower slot 110 and an upper slot 210 are formed in the lower buffer
portion 100 and the upper buffer portion 200, respectively, such that the lower slot
110 and the upper slot 210 vertically extend to form a vent and are coupled to each
other.
[0017] Specifically, it is as follows:
The lower buffer portion 100 is made of a lightweight material such as EPS, EPP, PU,
EPU, EVA, etc. that absorbs an impact, and is preferably extruded and molded.
[0018] The frame 300 which is an outer shell made of synthetic resin wraps around front
and side surfaces of the lower buffer portion 100 and is adhered and coupled thereto.
[0019] A plurality of lower coupling portions 120 protruding are formed on an upper surface
of the lower buffer portion 100.
[0020] A level down portion 130 is formed between the plurality of lower coupling portions
120.
[0021] In addition, a plurality of hollows are perforated in the level down portion 130
to form a vertical vent 140 that discharges heat generated from the user's head and
introducing fresh air from the outside.
[0022] The upper buffer portion 200 is made of a lightweight material that absorbs the impact
in the same manner as the lower buffer portion 100.
[0023] The frame 400 which is an outer shell made of synthetic resin wraps around front
and side surfaces of the upper buffer portion 200 and is adhered and coupled thereto.
[0024] A plurality of protruding upper coupling portions 220 are formed on the lower surface
of the upper buffer portion 200.
[0025] A level down portion 230 is formed between the plurality of upper coupling portions
220.

in which a lower buffer portion and an upper buffer portion are combined according
to the present invention.
[0027] FIG. 5 is an enlarged view of a dotted line in FIG. 4.
[0028] As shown in FIGS. 4 and 5, the lower slot 110 and the upper slot 210 extend vertically
to form a ventilation hole through coupling of the lower buffer portion 100 and the
upper buffer portion 200.
[0029] In addition, a level-down lower horizontal vent 150 is formed in the lower coupling
portion 120, and a level-down upper horizontal vent 250 is also formed in the upper
coupling portion 220, such that when the lower coupling portion 120 and the upper
coupling portion 220 are coupled to each other, the lower horizontal vent 150 and
the upper horizontal vent 250 are coupled to each other from the top and bottom at
the same position to form one large vent.
[0030] Accordingly, an air passage that continues to the vertical vent 140, the level down
portions 130 and 230, the lower horizontal vent 150 and the upper horizontal vent
250 may be formed, thereby ensuring user comfort.
[0031] FIG. 7 is a schematic diagram of an impact energy dispersion process according to
the present invention.
[0032] In FIG. 7, a PC shell is the frame 400, an EPS means the upper buffer portion 200,
and a buffer space means the level down portions 130 and 230.
[0033] Specifically, the most important feature of the present invention consists in that
the upper buffer portion 200, which is the outermost layer, firstly absorbs an impact
energy of the impact applied from the outside, the buffer space formed by the level
down portions 130 and 230 disperses the impact energy, and the lower buffer portion
100, which is an inner layer, secondly absorbs the remaining impact energy that does
not disperse.
[0034] In addition, a separate impact buffer material may be inserted or filled in the level
down portions 130 and 230 on the premise of being lightweight. As the separate impact
buffer material a material such as styrofoam may be used, and a gel-type impact buffer
material or a viscoelastic impact buffer material may be inserted or filled.
[0035] When the lower coupling portion 120 and the upper coupling portion 220 are coupled
to each other, a coupling means may use an adhesive material, and may be thermally
fused according to the materials of the lower buffer portion 100 and the upper buffer
portion 200.
[0036] Moreover, although not shown, when a hinge means or a detachment means is applied
between the frame 300 and the frame 400, as a result, the lower buffer portion 100
and the upper buffer portion 200 may be configured to freely detach and attach for
cleaning or parts replacement.
