OBJECT AND FIELD OF INVENTION
[0001] The present invention relates to a neck protection device for persons subjected to
risk of injury, and specifically for motorcycle users. It is a system that can be
easily integrated with the clothing, and which when used together with a helmet reduces
the risk of neck injury.
BACKGROUND OF THE INVENTION
[0002] Neck-protection devices are increasingly being used in various sports, such as motorcycle
riding. This is mainly due to the protection they provide to an area of the body that
is particularly vulnerable.
[0003] The protection method of these devices is based on limiting extreme motions of the
head, which would lead to neck injury, both towards the front (flexion) and towards
the back (extension), as well as towards the sides.
[0004] Different types of neck protectors exist. The most basic ones are composed of a foam
that surrounds the neck. Some examples of these are documents
US 6058517 and
WO 02089620.
[0005] These describe foams which, when placed around the neck, limit the movement of the
helmet to a greater or lesser extent. They are fitted through a front opening closed
by a strap, joined to one of the ends of the foam and attached to the other end by
Velcro unions.
[0006] The main drawback of these protectors is that they are sometimes adjusted too close
to the neck, which may make them uncomfortable, and other times do not stay in the
optimum position for limiting the movement of the helmet, with the resulting loss
in efficacy of the protection they must provide.
[0007] In addition to these, there are protectors that comprise a rigid structure on which
the helmet rests, which extend over the back and chest and ensure an optimum position
with respect to the neck and improve the load distribution. Some clear examples of
this type are the devices described in documents
WO 2005051251 and
WO 2008105010.
[0008] Thus, document
WO 2005051251 describes a device that comprises a ring placed around the neck, formed by two parts
that are joined at the sides and a support, connected to the rear part of the ring,
that extends over the user's back. The device described guarantees a greater stability,
but it is difficult to place and take off, as its clasps are on the sides, it does
not easily integrate with the user's clothing and it is cumbersome, complicating its
transport and storage. Moreover, as the area that rests on the back is not completely
covered in foam, it may become embedded in the spinal column and damage it.
[0009] Document
WO 2008105010 describes a similar device, which comprises a ring formed by two arms joined by articulation
means at a vertical shaft on the rear and which opens in the front, and a support
that runs from the ring on the upper part of the user's back A second shaft, horizontal
and parallel to the user's back, allows changing the angle between the ring formed
by the two arms and the rear support. The design of this device simplifies its installation,
as it is opened and closed on the front, its transport and its storage, as its various
component parts can be easily disassembled, but presents some serious drawbacks. Among
these is that, although it can admit a conventional clothing item open in the middle,
it can only be joined to the collar at the rear protector area, due to the vertical
shaft, and that its opening system does not allow incorporating any mechanism for
adjusting it to different user sizes.
[0010] Finally, there are devices in which the structure that conforms the collar is jointed
to the helmet or incorporated in a specific clothing item.
[0011] Thus, document
WO 2005079614 describes a protection device for motorcycle users composed of a helmet and a collar
that are joined to each other, behind the neck, by a mechanism that allows moving
the head freely without exceeding the limits beyond which there is a risk of serious
injury to the neck. The collar is composed of two arms articulated about a central
part. Among the main drawbacks of this device is that it cannot be used with any commercially
available helmet, as the helmet and collar are joined, and the deficient support on
the user's upper body, which among other reasons is due the absence of a support that
extends over the back.
[0012] In document
WO 2008/050303, in contrast to the above-described device, the collar is incorporated in a motorcycle
riding suit instead of being joined to the helmet. The collar comprises two parts
and is separated at a junction line that is prolonged in a side opening made in the
riding suit for this purpose.
[0013] None of the devices described above can be placed or removed together with the user's
clothing, and must be fitted before or after the clothing (jacket, riding suit, shirt,
etc.).
[0014] Therefore, it is an object of the present invention to provide a neck protector allowing
a simple and quick integration with the user's clothing.
[0015] A further object of the present invention to provide a neck protector that can be
placed and removed together with the user's clothing.
[0016] Yet another object of the present invention to provide a neck protector that can
be adjusted to different sizes in a simple manner and without requiring to change
parts.
DESCRIPTION OF THE INVENTION
[0017] To achieve the aforementioned objectives, a neck protector has been conceived composed
of a rear shield that rests on the shoulders and on the upper part of the back, and
two front shields that rest on the upper front part of the torso, one on either side
of the neck. Said front shields are connected to the rear shield by articulation means
having their rotation axes oriented towards the top, towards the back and towards
the centre, such that their point of intersection is above and behind them. These
articulation means can be embodied in different ways. In a first variant they can
consist of rigid hinges. In a second variant, the articulation means can be deformable
and consist of a simple flexible sheet, such as a rubber sheet or a textile strap.
In this case the rotation axes are not fixed and admit a certain spatial play, which
further simplifies the handling of the device.
[0018] The basis of the invention lies in that the rotation axes of the articulation means
follow, in some way, the natural line of the shoulders.
[0019] Both the front and rear shields can be fastened to the clothing by Velcro type attachment
areas or other fast-clip systems.
[0020] In turn, thanks to the special orientation of the pins of the hinges that articulate
the rear and front shields, the neck protector can be placed and removed jointly with
the clothing.
[0021] The front and rear shields that conform the neck protector are advantageously built
from a rigid frame and a deformable foam-like covering, meant to cushion the contact
between the helmet and the protector, and between the latter and the thorax.
[0022] The possibility is foreseen of incorporating specific protections surrounding the
rear frame, both in the upper area to cushion possible impacts between the driver
and a passenger in the back, and in the lower area to prevent damage to the user's
spinal column in case of penetration of the lower part of the frame
[0023] The two front shields can be separated from each other in the chest area, at a distance
such that it is possible to raise and lower the zipper of a clothing item, providing
a quick access to its interior. This arrangement also allows an increased ventilation.
[0024] Optionally, it has a system for joining the two front shields composed of a slide
that retracts inside on one of them and which, when extended, is fastened to a clasp
placed on the other front shield.
[0025] In order to simplify its storage and transport, a quick connection system can be
incorporated between the front and rear shields that allows separating the three parts
of the neck protector.
[0026] Optionally, a guide-slide system can be included with several locking positions,
which allows adjusting the neck protector to different body sizes without requiring
changing any parts.
[0027] The advantages of the neck protector of the invention are many:
- Limiting, by gradual deceleration, extreme movements of the head that can cause damage
to the neck.
- Allowing a simple integration of the protector with the user's clothing.
- Allowing to place and remove the protector jointly with the clothing.
- Allowing a fast access to the interior of the clothing.
- Improving ventilation.
- Simplifying its fast and safe removal after an accident, for example, if the user
must remain immobilised.
- Cushioning impacts between the user and a passenger on the back.
- Preventing damages to the spinal column due to forces applied in localised areas.
- Adjusting the protector to different sizes in a simple manner.
- Minimising the space it occupies when disassembled, in order to simplify its storage.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0030] The figures show an embodiment of the neck protector (001) of the invention, which
comprises a rear shield (100) that rests on the shoulders and the upper part of the
user's back, and two front shields (251) (252) that rest on the upper front part of
the user's torso.
[0031] The rear shield (100) is composed of a rigid rear frame (101) and a rear deformable
coating (102). It has an opening in the area on which it rests on the back in order
to improve ventilation and reduce its weight.
[0032] The front left shield (251) is composed of a front left frame (201) and a front left
deformable coating (203).
[0033] Similarly, the front right shield (252) is composed of a front right frame (202)
and a front right deformable coating (204).
[0034] The deformable coating (102) (203) (204) of all the described parts comprises a viscoelastic
foam sensitive to the deformation speed, meant to increase user comfort and absorb
energy in case of an accident, slowing down in a programmed manner the impact of the
helmet against the neck protector (001), and that of the latter against the user's
body. This reduces the biomechanical injury values, such as the rotational acceleration
of the head.
[0035] On the rear frame (101), specific foam areas have been introduced (see figure 3)
that cover it to constitute an upper protection (121), meant to cushion potential
impacts between the driver and a passenger in the rear, and a lower protection (122),
meant to prevent possible damage to the user's spinal column, by minimising the localised
forces that can be transmitted to the column.
[0036] In order to place and remove the neck protector (001), hinges (301) (302) have been
fitted that articulate the front shields (251) (252) with respect to the rear shield
(100), their axes of rotation being oriented towards the top, towards the back and
towards the centre, so that their point of intersection (O
1) is located above and behind them. In this way, the front shields (251) (252) open
to the sides and upward. See figures 5 and 9.
[0037] The front shields (251) (252) are connected to the rear shield (100) by a quick connection
system that allows a simple separation of the three parts of the neck protector (001),
allowing on one hand its storage in a reduced space and on the other its quick and
safe removal after an accident.
[0038] This attachment system comprises some housings (311) (312) disposed on the rear shield
(100) and the corresponding forks joined to the hinges (301) (302) (shown in figure
6) which, when inserted in said housings (311) (312), are attached to them.
[0039] In the surface of contact with the user's body, union areas (111) (112) (211) (212)
have been provided for including Velcro or other fast connection systems, in order
to fasten the neck protector (001) to the user's clothing (jacket, riding suit, sweater,
etc.). See figure 8.
[0040] These union areas can also be used to incorporate a possible system of straps for
attaching the neck protector (001) to the user's thorax, if it is not attached directly
to the clothing.
[0041] Attaching the neck protector (001) to the user's clothing, as described above, thanks
to the kinematics of the opening system, allows users to place and remove the neck
protector (001) together with a jacket or the like, the two items remaining connected
at all times.
[0042] With the neck protector (001) in its closed position (see figure 8), the front shields
(251) (252) can be separated in the front area by a distance such that it is possible
to raise and lower the zipper of a jacket, riding suit or any other clothing item
worn under the neck protector (001). This arrangement also allows an increased ventilation.
[0043] The collar that the protector defines around the neck can be closed to provide the
necessary stability in two different ways:
- a) If the neck protector (001) is fastened to the user's clothing (jacket, riding
suit, etc.) as indicated above (Velcro unions or the like), the same zipper or closing
system of the clothing item can be used as a closing element for the protector;
- b) By a union system included in the front part of the front shields (251) (252) which,
in its open position, does not interfere in the space that may exist between them;
This system can be used, in addition, even if the neck protector (001) is connected
to the clothing and the latter's closure system (zipper, etc.) is used.
[0044] Said union system between the front shields (251) (252) is shown in figure 10 and
comprises:
- A slide (416) that moves in a box (412) attached to one of the two front shields (252)
or (251). This mechanism has an elastic mechanism, such as a spring, that exerts a
force that tends to retract the slide (416) into the box (412);
- A clasp (405) that moves on a support (401) integrally joined to the other anterior
shield (251) or (252), which retains the slide (416) when it is moved far enough to
reach the clasp (405). This clasp (405) also has an elastic mechanism, such as a spring,
that exerts a force that tends to keep it in a closed position.
[0045] The movements needed to lock and release this union device are simple and have a
single direction.
[0046] To adapt the neck protector (001) to different sizes, on either side of it is mounted
a guide-slide system, shown in figures 2 and 3 and in detail in figure 6, with the
corresponding locking mechanism comprised of:
- A locking screw (313) (314), housed in the lateral guides (317) (318) joined to the
front shields (251) (252), with its linear motion along its axis restricted and fitted
with stops to limit its range of rotation.
- A locking nut (315) (316), also housed in the lateral guides (317) (318) and threaded
on the looking screw (313) (314), which has its rotation motion restricted but can
move linearly;
- A stem (309) (310) that slides through the lateral guides (317) (318) and has several
orifices in which the locking nut (315) (316) can be inserted. It can also comprise
one or more stops at its end, to prevent it from moving out of the lateral guide (317)
(318) when the locking nut (315) (316) is out of the orifices of the stem (309) (310).
[0047] Figures 1 and 2 show the ease of removal of the neck protector object of the invention.
It can be seen that the special configuration of the protector allows it to follow
the motion of the clothing item easily, as if it were part of its collar. It is interesting
to note that, even if the collar and the clothing item are not connected, it is possible
to open and reach the interior of the clothing item by pulling somewhat on the collar
without removing it.
[0048] A more detailed explanation is not considered necessary of some mechanical solutions
which, in general, will be known to persons skilled in the art.
