Moreover the helmet comprises in a known manner a cap (13) as well as a head band (14), and can also include a pivoting facial shield (15).
  • The main outer shell (2) is comprised by a substantially spherical wall of vertical plane of general symmetry (P) which is made advantageously from composite material of the type comprising for example a stacking of layers of reinforcing fibres, impregnated and linked to one another by a resin matrix. The fibres can be glass, aramid, Nylon, polyethylene or carbon fibres, while the matrix can be a resin of the thermosetting or thermoplastic type. Of course, the shell could be of any other material as, for example made by injection of a plastic material, and advantageously of a filled plastic material.
  • The main outer shell (2) comprises several wall portions, as is shown in FIG. 1, i.e. an upper front wall portion (3) extended towards the rear by an upper rear wall portion (4), itself extended towards the bottom by a lower rear wall portion (5), and further comprises two lateral wall portions (6 a, 6 b).
  • The upper front portion (3) corresponds to the area occupied by the forehead of the user and is limited by the upper edge (7) of the facial opening (8) which is limited laterally by two lateral edges (9 a, 9 b).
  • The upper front wall portion (3) corresponds to the area occupied by the skull of the user, while the lower rear wall portion (5) corresponds to the area occupied by the nape of the user.
  • Add to this that the wall of the shell is limited towards the bottom by a lower edge (10). The lateral wall portions (7 a, 7 b) correspond to the areas occupied by the ears of the user and are limited towards the front by the corresponding lateral edge (9) of the facial opening (8) and towards the bottom by the lower edge (10).
  • According to the invention, the safety helmet (1) comprises means of maintaining the main shell (2) constituted by an inner helmet shell (11).
  • Moreover this inner helmet shell (11) provides the retaining of the chin strap (12) allowing the adjustment and the fastening of the helmet (1) on the head of the user.
  • The inner helmet shell (11) has the form of a substantially circular wide strip made of plastic material, constituted by a peripheral wall. According to the invention the main outer shell (2) is attached in a releasable manner to the inner helmet shell (11) thanks to releasable means of connections. These means are constituted by at least three points of connections of the first means integral with the inner helmet shell (11) intended to interact with second means integral with the main outer shell (2).
  • According to the preferred embodiment given by way of example the main outer shell (2) is attached to the inner helmet shell (11) in four points, i.e. a rear point (16), a front point (17), two lateral points (18 a, 18), a left lateral point (18 a) and a right lateral point (18 b).
  • The rear point of fastening (16) is realised by a projection interacting with a hollow. As such, the inner helmet shell (11) comprises an embedding cup (19) intended to interact with a rear projection (20) of corresponding dimension projecting towards the interior of the main outer shell, on the lower rear wall portion (5).

As such, each one of the fastening projections (24 a, 24 b) is engaged in a hole (180 a, 180 b) of the lateral wall of the shell as well as in the fastening hole (23 a, 23 b) of the inner helmet shell, and its locking is provided by the locking pin which is engaged in a corresponding hole (240) made in the fastening projection.
  • The fastening projections (24 a, 24 b) are independent parts, which are for example coming from lateral hooking parts (30) intended for example for attaching a respiratory mask, or a lighting lamp, even a pivoting facial shield.
  • Add that according to the preferred embodiment of the invention such as is shown, the inner helmet shell is also intended to retain the chin strap (12). To this effect, the peripheral wall of the inner helmet shell comprises a set of holes (26 a, 26 b-27 a, 27 b) intended for the passage of the straps of the chin strap. The latter is therefore attached to the inner helmet shell (11), not to the shell (2) as is the case in conventional helmets.
  • Also note that the cap (13) which is also attached on the inner helmet shell (11) by a clipping means. It is therefore the inner helmet shell that retains this cap.
  • Add that the helmet of the invention comprises a comfortable lining (28), installed under the cap which is intended to be in contact with the head of the user and provide him with good wearing comfort.
  • Moreover, the helmet comprises a head band (14). Said band with the chin strap provides the maintaining of the helmet on the head of the user.
  • The head band (14) which is constituted by a peripheral strip is attached to the inner helmet shell (11). The band (14) is made for example of deformable or similar plastic material, in such a way as to be able to hug the periphery of the head of the user in order to provide a good retaining of the helmet and this with an optimal comfort. Note that the peripheral dimension of the strip can be adjusted in order to adapt to the morphology and particular to the dimensions of the head of the user. To this effect, means for adjusting are provided as for example those described in French patent application 0605223.
  • As such, the assembly of the helmet requires little manipulation and is accomplished without any particular tools.
  • The cap (13) is in a first step clipped on the inner helmet shell (11). Then the shell is installed on the inner helmet shell. For this, the rear embedding cup (19) of the inner helmet shell is engaged around the rear projection (20) of the shell, then the front of the inner helmet shell is pivoted in order to clip to the front projection (22) of the shell in the embedding housing (21) of the inner helmet shell (11) and this via deformation of the front locking tongue (210). The shell is then in its position in relation to the inner helmet shell, and each one of the moveable fastening projections (24 a, 24 b) are then engaged in a hole (180 a, 180 b) of the lateral wall of the shell as well as in the fastening hole of the inner helmet shell (11), and its locking is provided by the locking pin which is engaged in a corresponding hole (240) made in the fastening projection.
  • The chin strap (11) is advantageously of the three-point or four-point type and is constituted in a known manner by a set of flexible straps with chin guard.
