Description
TECHNICAL FIELD
[0001] The present invention relates to an improved multi-layer
safety helmet that and protects the head by dispersing the impact
energy of an external impact to prevent the impact energy from

developed an improved multi-layer safety helmet of 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 to minimize the transfer of impact to an
inner layer.

BEST MODE FOR CARRYING OUT THE INVENTION
[0014] In an embodiment of the present invention, an improved
multi-layer safety helmet comprising: 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
portion 200 and is secondly absorbed by the lower buffer portion
100.
[0015] Hereinafter, preferred embodiments of the present invention
will be described in detail with reference to the accompanying
drawings.
[0016] FIG. 1 is a view showing a lower buffer portion viewed from
the top according to the present invention.
[0017] FIG. 2 is a view showing an upper buffer portion viewed from
the top according to the present invention.
[0018] FIG. 3 is a view showing FIG. 2 viewed from the bottom.
[0019] The improved multi-layer safety helmet of the present
invention comprises: 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 portion 200 and is
secondly absorbed by the lower buffer portion 100.
[0020] And, a frame 300 is integrally coupled to the lower buffer
portion 100.
[0021] A frame 400 is integrally coupled to the upper buffer
portion 200.
[0022] 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.
[0023] Specifically, it is as follows.
[0024] The lower buffer portion 100 is made of a lightweight
material such as EPS, EPP, PU, EPU, EVA, etc. that absorb an
impact, and is preferably extruded and molded.
[0025] 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.
[0026] A plurality of lower coupling portions 120 protruding are
formed on an upper surface of the lower buffer portion 100.
[0027] A level down portion 130 is formed between the plurality of
lower coupling portions 120.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] A plurality of protruding upper coupling portions 220 are
formed on the lower surface of the upper buffer portion 200.
[0032] A level down portion 230 is formed between the plurality of
upper coupling portions 220.
[0033] FIG. 4 is a view showing an improved multi-layer safety
helmet of the present invention in which a lower buffer portion and
an upper buffer portion are combined according to the present
invention. FIG. 5 is an enlarged view of a dotted line in FIG.
4.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] FIG. 7 is a schematic diagram of an impact energy dispersion
process according to the present invention.
[0038] 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.
[0039] Specifically, the biggest feature of the present invention
is 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.
[0040] 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.
[0041] 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.
[0042] And 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.
[0043] While the present invention has been described with
reference to the preferred embodiments, the present invention is
not limited to the embodiments, and various modifications may be
made by those skilled in the art within the scope of the present
invention.
INDUSTRIAL APPLICABILITY

the prior art as described above. It is an object of the present
invention to provide an improved multi-layer safety helmet that
consists of two or more layers of a buffer material and forms a

space before transferring the impact to an inner layer, and then
transfers the minimized impact to the inner layer.
