Definitions

• the present invention relates to an improvement for a protective helmet comprising a chin strap.
• the invention relates more particularly to the chin rest.
• Protective helmets have long been in common use in various fields, either professionally, as is the case for the military, pilots of aircraft or helicopters, gendarmes or firefighters, or civil or private, as is the case for users of motorcycles, rally or racing cars, or employees of construction sites.
• helmets which include a rigid outer shell of substantially spherical shape, equipped with an internal covering, and intended to fit onto the user's skull while providing the front has a facial opening.
• helmets generally include an internal shell of synthetic foam intended to absorb shocks.
• Some helmets also include a chin guard to protect the user's jaw. But traditional chin rests, even if they improve the level of protection, do not provide maximum protection.
• the present invention proposes to solve the drawbacks of traditional chin rests by proposing a new chin rest which provides maximum protection.
• the invention relates to a protective helmet of the type constituted by an external shell intended to protect the head of a user, and comprising a main chin rest, characterized in that it comprises at least one movable secondary chin rest forming protective flap.
• the secondary chin rest is movable in pivoting about a transverse axis to be movable in pivoting relative to the chin rest main between two positions, namely, between a low active position of low protection, and a high retracted position.
• the secondary chin rest has the shape of an arch, and is articulated on the main chin rest.
• the secondary chin rest is articulated inside the main chin rest.
• the main chin rest is removable, so that it can be put on or taken off by the user.

• the other connection means is located near the transverse axis of pivoting of the visor.
• each lateral portion of the helmet has a recess of complementary shape with a part of the amount of the main chin guard.
• connection means cooperate with the snap connection means.
• connection means of the main chin guard are in the form of tongues.
• the latching of the tongue located in the area close to the joint between the side edge of the helmet and the front end of the bottom edge of the helmet is produced by localized deformation of the wall of the helmet in the form of a groove.
• the latching of the tongue located in the area remote from the joint is achieved by locking a latch pivotally mounted in the lateral portion of the helmet between an active tongue locking position and a passive unlocking position of the tongue.

• FIG. 6 is a sectional view showing an alternative of the chin strap connected to the shell at the bottom connection means.
• the helmet (1) equipped with the chin guard according to the invention can be of any type, such as, for example, of the type used by firefighters, soldiers or bikers, or even cyclists or skiers. It comprises a main external shell (2) protecting the skull and the neck of the user and has a front facial opening (3) in the area occupied by the actual face of the latter, said helmet having a vertical longitudinal plane ( P) of general symmetry.
• the shell (2) is made of rigid material and can be of any suitable material such as plastic, steel, aluminum or composite material of the type comprising a stack of layers of reinforcing fibers, impregnated and bonded together by a resin matrix.
• the outer shell (2) is constituted by a substantially spherical wall comprising several wall portions, namely, an upper front wall portion (4) extended rearwards by a rear portion upper wall (5), itself extended downwards by a lower rear wall portion (6), and moreover comprises two lateral wall portions: a straight lateral wall portion (7a) and a lateral portion left of wall (7b).
• the upper front portion (4) corresponds to the area occupied by the user's forehead and is limited by the upper border (8) of the facial opening (2) which, in turn, is limited laterally by two lateral borders. (9a, 9b).
• the upper rear wall portion (5) corresponds to the area occupied by the user's skull, while the lower rear wall portion (6) corresponds to the area occupied by the user's neck.
• the shell wall (2) is bounded downwards by a lower border (10).
• the lateral wall portions (7a, 7b) correspond to the areas occupied by the ears of the user and are bounded forwards by the corresponding lateral border (9) of the facial opening (3), and downwards by the front ends of the lower edge (10).
• the helmet may also include a protective face shield (30) movable in pivoting around a transverse axis (300) between two positions, namely, a low active face protection position (FIGS. 1 to 2b), and a position high retracted (Figure 3).
• a protective face shield (30) movable in pivoting around a transverse axis (300) between two positions, namely, a low active face protection position (FIGS. 1 to 2b), and a position high retracted (Figure 3).
• the helmet (1) comprises a main chin guard (11) and according to the invention at least one movable secondary chin guard (12) forming a protective flap.
• the secondary chinrest (12) is pivotally movable about a transverse axis (13) to be pivotally movable relative to the main chinrest (11) between two positions, namely, between a low active protective position such as that is illustrated in FIG. 1, and a high retracted position as illustrated in FIG. 2.
• the main chinrest (11) has, in a manner known per se, the shape of a rigid arch connecting the two side walls (7a, 7b) of the helmet.

• the spacing between the two lower tabs (140a) opposite is slightly greater than that between the two side walls (7a, 7b) of the helmet so that the user has to slightly pre-stress arms before introduction into the helmet (2).
• This bottom connection means can advantageously avoid untimely rotation of the chin strap relative to the helmet.
• the secondary chin rest (12) has the shape of an arch, and is articulated on the main chin rest (11). It has been understood that when the user when he has the right head not only has his jaw protected by the main chin guard, but his neck is also protected by the secondary chin guard which is in the low protective position.
• the stop system (15) consists essentially of the shoulder (24a) formed in the inner wall (25) of the main chin guard (11) at its edge lower (26) and in abutment against the shoulder (24b) formed in the outer wall (27) of the secondary chin rest (12) at its upper edge (28).
• the secondary chinrest (12) can be mounted articulated outside the main one (11).
• the internal wall of the secondary chin rest (12) is in its high retracted position opposite the external wall of the main chin rest.
• connection means than snap-on means can be provided of the buttonhole or fastening type of textile type gripping marketed under the brand Velcro. Whatever they are the connection means provided, such as those described in the illustrated embodiment, they will be provided so that beyond a certain tensile force exerted on the chin guard according to the invention, the latter disconnects of the helmet.
• Such connection means make it possible to prevent the user of the helmet with chin guard according to the invention, from being able to be pulled by a malicious individual exerting a force on the chin guard, the latter being released. This can be particularly advantageous when the helmet according to the invention is a helmet intended for use by users of the police force, such as the police.
