Title of invention: PROTECTIVE HELMET WITH EARPIECES
FIELD OF INVENTION
[0001] The present invention is related to protective helmets for vehicle
drivers, which improve
the user's spatial perception.
BACKGROUND
[0002] US Patent US6347412 discloses an apparatus for diverting sound from a
generally
backward direction of a user to the user's ears. The apparatus includes a
sound reflector that
can be used by the user directly or can be connected to a separate support
such as a helmet.
The connection between the sound reflector and the helmet can be fixed or
adjustable. When a
helmet support is used, the apparatus may include a spacer located between two
sound
reflectors. The separator directs the sound to each of the two reflectors. The
addition of
dampening cushions helps sound reflectors divert air around the user's ears to
reduce the
sound of the wind and increase the user's ability to hear sounds originating
from a backward
direction.
[0003] Japan's Patent JP2010047886 refers to a helmet that includes holes to
cancel its
sealed state, a wind noise suppressor that covers the corresponding holes to
prevent the
formation of turbulent flow and auditory normalization means to prevent the
generation of
associated noise with the wind.
[0004] US Patent US3797040 discloses a protective helmet for use by a
motorcyclist and
comprises a pair of manually controlled ear lids or flaps, which are installed
for coercion with
hearing ports located in line with the ear of the user. When the tabs are
completely open, they
remain in this position until they are intentionally closed by the user. Each
door or flaps
comprises a rubber gasket to provide a hermetic seal while the motorcycle is
in motion.

[0005] US Patent US3021526 mentions a helmet comprising ear covers, means
mounted
thereon for supporting ear cushions on each cover, wherein each of the means
includes a
series of substantially rigid telescopic rings arranged concentrically, of a
rectangular cross
section, and of progressively decreasing diameter. Each successor ring is
dimensioned to allow
substantial lateral movement relative to the next larger adjacent ring when
said ring is fully
telescopic within the larger ring. Additionally, the hull comprises diaphragms
connecting the
successive rings and being attached to the inner edge of a ring and to the
outer edge of the
next adjacent ring, and means for securing the ear cushion to the innermost
ring.
[0006] China's Patent CN2172578, mentions a prismatic helmet with sense of
hearing, which
comprises convex edges, hearing orifices, and a hearing cover. The prismatic
helmet has a high
durability and ensures safe driving; It can be used by motorcyclists and by
drivers of several
uncovered motor vehicles.
SUMMARY OF THE INVENTION
[0007] The inventor has identified the need in the technical field for a
helmet for drivers of
uncovered vehicles that increases the driver's spatial perception of location
and distance of the
environment, reducing the risk of vehicular accidents.
[0008] The inventor provides a protective helmet comprising an internal
structure and an
external structure, which recreate the acoustic shape of human ears, avoiding
the reduction of
perception while driving a vehicle. These structures are arranged
perpendicular to the auditory
canal of each of the ears of the user, allowing the driver's awareness in
audible frequencies of
the environment. Additionally, the inventive protective helmet can utilize a
noise filter and a
fabric, which reduce turbulence, recreating the acoustics of human ears.

DETAILED DESCRIPTION OF THE INVENTION
[0009] The helmet of the present invention comprises a shell (1) and on each
of its sides,
where the ears of the user are usually located, an internal structure (3) and
an external structure
(2). These structures recreate the acoustic form of human ears. The helmet
also comprises a
viewing hole in the shell (1).
[0010] The internal structure (3) is arranged inside the helmet, while the
external structure (2)
is disposed on the outside thereof and the two are coupled with the shell (1).
Both internal and
external structures (2 and 3) comprise hearing holes, which are aligned with a
hearing hole of

the shell (1), when said structures are coupled to the shell (1), allowing the
entry of sound from
the outside.
[0011] Particularly, the internal structure (3) may comprise an ear pad (4)
and a cone (5).
[0012] The external structure (2) may comprise an ear-shaped element (8) and
optionally a
liner (9).
[0013] The cone (5) may comprise a coupling trumpet (10) to the ear pad (4).
The ear pad (4),
the trumpet coupling to the ear pad (10) and the cone (5) each comprise a
hearing hole. The
hearing holes are aligned when the internal structure (3) and the external
structure (2) are
assembled to the shell (1).
[0014] Particularly, the trumpet (10) is inserted in the hearing hole (13) of
the ear pad (4), to
couple said pad (4) to the cone (5).
[0015] In a preferred embodiment of the invention, the cone (5) and the
trumpet (10) are made
of a ductile material, which makes it possible to deform the trumpet (10) to
insert it into the
hearing hole (13) of the ear pad (4). Preferably, the ductile material may be
silicone.
[0016] The ear-shaped element (8) comprises a hearing hole, which is aligned
with the
hearing ports of the ear pad (4), of the coupling trumpet (10) to the ear pad
(4), of the cone (5)
and the shell (1), when joining with the latter.
[0017] The ear-shaped element (8) can comprise holding structures (11) on its
internal face.
The cone (5) may comprise connecting holes (15) for receiving the fastening
structures (11).
Likewise, the shell (1) can comprise coupling holes (12) through which the
fastening structures
(11) of the ear-shaped element (8) pass, thus coupling both the cone (5) and
the element in
shape of ear (8) to the shell (1).

[0018] In a preferred embodiment of the invention, a filter (6) can be
disposed within the
hearing hole (16) of the cone (5).
[0019] Additionally, a piece of fabric (7) can be inserted into the hearing
hole (14) of the shell
(1) and into the hearing hole (17) of the ear-shaped element (8), said piece
of fabric being also
adhered to the hearing hole (16) of the cone (5). Optionally, the piece of
fabric adheres to the
cone (5), on top of the filter (6).
[0020] The external structure (2) may comprise a lining (9) on the ear-shaped
element (8), to
protect it from rain and foreign elements. The liner (9) can be fastened to
the wall of the internal
part of the ear-shaped element (8), for example by means of an adhesive.
[0021] All of the hearing holes (13, 14, 16, and 17) are aligned, and are
arranged
perpendicularly to the user's ear canal.
[0022] The sound signal enters through the external structure (2) and
transduces acoustically
to the cone (5). Subsequently, the trumpet (10) transmits the sounds to the
user's ear,
generating also a closure of the signal. Therefore, the ear accommodates the
perception by
psychoacoustics and perceives the relative location and distance of the sound
sources. Thanks
to the size of the cone that is attached to the ear of the user, it is
possible to increase the
perception of the audible and directional frequencies, which generate the
perception of location
and distance more easily for the user.
[0023] In a preferred embodiment of the invention, the ear pad (4) can be made
of imitation
leather, the filter (6) can be of windproof foam, the piece of fabric (7) can
be stuffed, the shell (1)
can be made of polycarbonate, the ear-shaped element (8) can be made of
silicone and the
lining (9) can be made of a fabric that is resistant to heat and UV rays.
However, this list is not
limiting and similar materials may be employed.
