    The present invention relates to an internal protective device for a helmet and a helmet thus equipped.
    It finds a general application in the cranial protection of hard shell helmet users such as drivers of motor vehicles with two or more wheels.
    It is known that during a road accident involving a motorcyclist the extraction of the helmet is not without impact on a traumatized cervical vertebral column. This extraction by strong traction in the axis, can lead to neurological complications sometimes irreversible in an unconscious motorcyclist. The non-extraction of the helmet is often incompatible with the clearance of the upper airway during the first stage of the rescue.
    [0004] Internal helmet protection devices are already known comprising a hard outer shell, a flexible inner cap disposed inside the shell and a chain of air cushions inserted inside the helmet between the head and the protect and the inner cap. In practice, the chain of air cushions comprises a valve opening out of the helmet so as to allow an emergency deflation by the rescuers.
    Even if the air cushions can be deflated quickly and simply on the road by the lifeguards, the helmet and equipped does not provide total satisfaction in terms of protection against violent shocks.
    The object of the invention is to further improve the situation.
    An object is in particular to provide a helmet whose damping properties are improved over the helmets of the prior art.
    For this, the invention relates to an internal protective device for a helmet comprising a hard outer shell, a flexible inner cap disposed inside the shell and a chain of air cushions intended to be placed on the inside. inside the helmet between the soft inner cap and the head to protect.
    According to a general definition of the invention, the flexible inner cap comprises a layer of flexible material of predefined thickness inside which is formed a plurality of cavities whose shape, number, depth and shape. are selected, dimensioned and conjugated with the air cushions so as to improve the damping properties of the helmet and cover the parts of the head to be protected from the user when the air cushions are filled with air while allowing a simple extraction of the helmet when the air cousins are deflated.
    Surprisingly, the applicant has observed that the number, size, and depth of the cavities formed in the flexible inner cap and their combination with the air cushions not only allow a good anchoring of the cushions in the cap but also to obtain a deformation by bending and / or buckling of said flexible cap under the pressure of the air cushions in case of shock, which further improves the damping properties of the helmet.
    According to some embodiments, the device further comprises one or more of the following characteristics, taken (s) separately or in any technically possible combination: the thickness of the inner cap is between 20 to 45 mm according to the size of the helmets. the depth of the cavities is of the order of 10 to 25 mm depending on the size of the helmets. the air cushion chain is formed of two plastic walls interconnected at their periphery and comprises a main band formed of a plurality of air cushions for protecting the neck of the user, a first side band attached to the main band and formed of a plurality of air cushions for protecting a temple and cheek of the user, a second side band joined to the main band and formed of a plurality of cushions air for the protection of the other temple and the other cheek of the user; and a central band joined to the main band between the first and second sidebands and formed of a plurality of air cushions for the protection of the neck and the user's parietal shield while the cavities. The air cushions are identical in shape and spherical in shape and have a diameter of between 2 and 6 cm depending on the size of the helmets. the air bag comprises a valve opening out of the helmet so as to allow an emergency deflation by the rescuers. the valve is located on an external lateral face of the hard shell of the helmet. the valve comprises a flexible material tip protected by a removable rigid shell and adapted to the hard shell of the helmet.
    The device further comprises an associated inflation system.
    The present invention also relates to a hard shell helmet comprising an internal protection device according to any one of the preceding features.
    [0013] Other advantages will become apparent from the description in which: FIG. 1 diagrammatically represents the protection device according to the invention, in which the air cushions are anchored in the cavities of the inner cap, seen from below; Figure 2 shows schematically the chain of air cousins according to the invention, piaced out of the helmet; and Figure 3 shows schematically a profile view of the helmet according to the invention protecting the head of a manikin.
    [0014] With reference to FIGS. 1 to 3, the helmet 2 comprises an outer hard shell 4, a flexible inner cap 6 disposed inside the shell 4 and a chain 8 of air cushions 10 intended to be pivoted to the inside of the helmet between the head to be protected 50 (FIG. 3) and the flexible inner cap 6.
    The chain of air cushions 8 is described in more detail with reference to Figure 2. It defines a chain 8 air cushions 10 individualized 10-1, 10-2, ... 10-i , 10-j, ... 10-n, 10-m, 10-p ... connected to each other.
    The outer hard shell 4 is made in one piece. For example, it is made of polycarbonate (PC). Alternatively, it is made of acrylonitrile butadiene styrene (ABS).
    The flexible inner cap 6 is made of flexible material, for example expanded polystyrene foam (EPS). Alternatively, it may be expanded polypropylene (EPP).
    The flexible cap 6 is designed to surround the head to protect 50.
    The flexible cap 6 comprises a layer of flexible material of thickness E. Very advantageously, a plurality of cavities 100, individualized in 100-1, 100-2, ... 100-i, 100-j, .. .100-n, 100-m, 100-p ..., represented by weakening lines 102, individualized at 102-1, 102-2, ... 102-i, 102-j, ... 102 -n, 102-m, 102-p ..., of respective depth P is formed inside the layer of the inner cap 6. For example, the cavities 100 are made during the manufacture of the helmet using of a 3D process.
    The thickness E of the inner cap is between 20 mm and 45 mm depending on the size of the helmets.
    The depth P cavities 100 is of the order of E / 2 and between 10 mm and 25 mm depending on the size of the helmets.
    The invention lies in the fact that the shape, number, depth and arrangement of the cavities 100 of the cap are chosen, dimensioned and conjugated with the air cushions 10 to allow not only a good anchoring of cushions in the flexible cap but especially to obtain deformation by bending and / or buckling of said flexible cap under the pressure of the air cushions in case of shock, which further improves the damping properties of the helmet.
    For example, the Applicant has tested the helmet according to the invention according to European standards ECE R22-05. The results of the shock absorption tests as well as the recordings over time of the accelerations experienced by the false heads show that the amount of energy transmitted to the skull is less than the authorized limit of 275 g.
    In practice the air pocket 8 formed by the chain of air cushions is in one piece (Figure 2). It is formed of two walls 83 and 85 of plastic bound together on their periphery. The shape and arrangement of the chain of cushions 10 inside the inner cap 6 covers the parts of the head of the user to be protected when the air bag is filled with air while allowing a simple extraction of the helmet 2 when the air pocket 8 is deflated.
    The air cushion chain 10 comprises a main band 9 formed of a plurality of air cushions for the protection of the neck of the user; a first side band 11 and 12 joined to the main band 9 and formed of a plurality of air cushions for the protection of a temple (not shown) and a cheek (not shown) of the user; a second side band 13 and 14 joined to the main band 9 and formed of a plurality of air cushions for the protection of the other temple (not shown) and the other cheek (not shown) of the user ; and a central strip 15 joined to the main band 9 between the first 11, 12 and second 13, 14 side strips and formed of a plurality of air cushions for the protection of the neck and parietal bone of the user. Thus all sensitive parts of the user's head are protected in case of violent shock.
    For example for a chosen helmet size, the main band 9 has a length of the order of 80 to 100 cm.
    In practice, the air cushions 10 are identical in size and spherical shape and diameter of the order of 2 to 6 cm.
    The plastic material of the air bag belongs to the group formed by polyurethane, polyurethane ether platinum, polyamide, polyamide 235 Dtex.
    For example, the plastic material is a Platilon Ethereal POLYURETHANE 4201 AU 300 micrometer.
    In another example, the plastic material is a polyamide-coated polyamide fabric 235 on one or both sides.
    In practice, the two walls 83 and 85 of the air pocket 8 are welded by an ultrasound machine.
    The air pocket 8 comprises a valve 19 opening out of the helmet so as to allow deflation urgently by the rescuers. In practice, the valve 19 is located on an outer lateral face of the hard shell 4 of the helmet. Advantageously, the valve 19 comprises a tip 21 of flexible material protected by a rigid shell (not shown) removable and adapted to the hard shell 4 of the helmet.
    According to yet another embodiment, the device further comprises an associated mini-compressor type inflation system integrated helmet (not shown). Alternatively, the inflation can be performed by the user or in the form of a fixed industrial pre-inflation.
    In practice, the inflation pressure is of the order of 1.5 to 2.5 bars, which gives good protection against violent shocks.
    For example a thin covering membrane 120 (Figure 3) covers the face of the chain of air cushions 8 in contact with the head 50 of the user.
    The shape and arrangement of the chain of air cushions 10, conjugated with the cavities 100 of the inner cap not only provides protection against shocks when the air bag is inflated but also a good circulation of air. air inside the helmet, which prevents sweating of the head. In addition the chain of air cushions is easy to be removed from the helmet which allows easy cleaning both inside and outside the helmet. Similarly, the fixing of the chain of cushions inside the cavities of the inner cap of the helmet is performed automatically by air pressure, without any additional fixation.
