Definitions
- the invention relates to a protective helmet with movable chin.
- helmets in particular those used for the practice of the motorcycle or ski, and more particularly its helmets comprising a shell on which are mounted mobile in rotation a chin guard and a shield (or visor ).
- Patent documents EP 0.993.784 (MOTIVE), EP 1.887.898 (ROOF) or FR 2.876.882 (SHARK) disclose protective helmets with screens and movable chinrests.
- this type of helmet usually comprises a rigid shell 1 for the protection of the user's skull box and comprising: a front face provided with a facial opening 1a, side walls 1b and a back side 1c.
- a protective screen 2 - or visor - allows to cover and protect the portion of the face of the user located at the level of his eyes.
- This screen 2 is rotatably mounted on the side walls 1b of shell 1.
- the screen 2 pivots around an axis of rotation 4 integral with the shell 1, between a downwardly folded position where it is positioned at the level of the face opening 1a and a retracted position upwards (dotted lines) where it releases said opening face.
- a chin guard 3 protects the portion of the face of the user located at the level of his chin and / or his jaw. It is rotatably mounted on the side walls 1b of shell 1 so that it can be raised over the screen 2, and be tilted towards the rear face 1c.
- the chinrest 3 pivots about the axis 4, from a closed position ( Figure 1) where it forms with the shell 1 a full face helmet and an open position ( Figure 2) where it releases the facial opening 1a.
- the open position is commonly referred to as the "jet" position.
- the screen 2 can pivot about the axis 4, the chinrest 3 is in the closed or open position. And conversely, the chinrest 3 can pivot about the axis 4, the screen 2 is in the folded or retracted position.
- the chin strap has an axis of rotation offset upwards with respect to the axis of rotation of the screen.
- This articulation is relatively complex to implement.
- the screen is supported by its lower end, at an inner edge of the chinrest.
- This arrangement has the advantage of being able to raise the chinrest while keeping the screen in the folded position.
- the force exerted by the air on the outer wall of the screen tends to drive the latter towards the back of the helmet and take off the edge Internal chinrest: the sealing is no longer ensured, This depression Also intervenes in case of impact or impact on the screen.
- the chinrest is also mounted movably in translation on the side shell walls so as to slide to an advanced position in front of said helmet.
- the screen rests at an outer rim of the chin guard.
- an object of the invention is to simplify the articulation of the chin guard, which articulation allows mobility in rotation and in translation of said chin guard.
- the invention also aims to provide a helmet whose chin strap is easily and quickly manipulated.
- the solution proposed by the invention is a hard hat comprising a rigid shell comprising: a front face provided with a face opening, side walls and a rear face, and wherein:
- a protective screen is rotatably mounted on the side shell walls between a position folded downwards where it is positioned at the level of the facial opening and a retracted position towards the top where it releases said facial opening,
- a chinrest is rotatably mounted on the side walls of the shell so that it can be raised over the screen, and be tilted towards the rear face, from a closed position where it forms with the shell a full face helmet and an open position where it releases the facial opening, which chin has lateral branches,
- the chinrest is also mounted movably in translation on its side walls of the shell so as to slide to an advanced position in front of said helmet, from a retracted position where it forms with the shell a full face helmet.
- This helmet is remarkable in that the lateral branches of the chin guard are slidably mounted on intermediate parts, which parts are rotatably mounted on the hull side walls.
- the rotational mobility of the chin rest is now ensured by a simple pivot connection between the connecting piece and the helmet shell, and the mobility in translation of the chin is provided by a simple slide connection between the connecting piece and said chin.
- the general articulation ensuring this double mobility of the chinrest is in fact very simple to make and use, and inexpensive.
- Each side branch of the chinrest is secured to a slider, which slider is slidably mounted in a rail arranged on one of the intermediate parts; which intermediate piece is rotatably mounted on one of the side walls of the shell, about an axis of rotation integral with said shell.
- the rail is advantageously rectilinear and oriented in the same direction as the lateral branch of the chin guard to which said rail is attached.
- a biasing member may be arranged to constrain the chinrest to the advanced position; in which case, a retaining member may be movably mounted between a locking position where it holds the chinrest in the retracted position and a retracted position where it releases said chinrest so that it can slide to the advanced position.
- a maneuvering member is advantageously provided for moving the chin guard from the retracted position to the advanced position.
- This operating member can act on the retaining member.
- said screen is maintained: - at its wall external, by an inner rim of said chin guard; - And at its inner wall, by a stop member arranged on said chin.
- This abutment member is preferably movable between a locking position where it bears against the inner wall of the screen and a retracted position where it releases said inner wall.
- An operating member may be provided to move the stop member from the locking position to the retracted position, which operating member is installed on the chinrest.
- the same actuator acts simultaneously on the retaining member and on the stop member.
- the abutment member constrains the screen against the inner rim of His chin rest.
- the helmet preferably comprises means for slaving the translational movement of the chin to the retraction of the stop member.
- the chin and the screen have the same axis of rotation, which axis is fixed relative to the hull.
- the chinrest is preferably installed on the hull so as to pivot from the closed position to the open position after sliding to the advanced position.
- FIG. 1 shows schematically a helmet according to the invention, in position "full face helmet",
- FIG. 2 above illustrates the helmet of FIG. 1 in the "jet" position
- FIG. 3 illustrates, on a helmet according to the invention, a device for holding the screen and a locking device for the chinrest: the abutment member associated with the screen and the retaining member associated with the chin strap both in the locked position;
- Figure 3a shows schematically the retaining member associated with the chinrest in the position illustrated in Figure 3;
- FIG. 4 shows the helmet of Figure 3 with: the stop member and the retaining member in the retracted position
- Figure 4a shows schematically the retainer associated with the chinrest in the position illustrated in Figure 4;
- FIG. 5 shows the helmet of Figures 3 and 4 with the chinrest in the advanced position
- FIG. 6 is an exploded view showing various elements capable of forming an articulation between the shell of the helmet and the chin strap;
- Figure 7 is a rear view of the hinge of Figure 6, further detailing an exemplary design of a chinrest retainer.
- the helmet object of the invention being identical on both sides of the longitudinal plane of symmetry (corresponding to the plane of the attached drawing boards), said helmet is shown only in side view in the accompanying figures.
- the helmet object of the invention is of the type described above with reference to FIGS. 1 and 2.
- the chinrest 3 is rotatably mounted on the side walls 1b of shell 1 so that it can be raised over the screen 2, and be tilted towards the rear face 1c, without necessarily reaching this position. In Indeed, the movement of the chinrest 3 can stop at the top of the shell 1.
- the chinrest 3 is for example made of a rigid shell, about 2 mm thick, polycarbonate, and is obtained by molding. It has lateral branches 33 whose distal ends 330 are connected to the side walls 1b at the axes of rotation 4 which are fixed relative to the shell 1. In practice, the chinrest 3 has a general shape in U or V of which the lateral branches 33 fit in - or alongside - the side walls 1b.
- the axes of rotation 4 are for example in the form of lugs, pins or rivets integral with the shell 1.
- the shell 1 comprises an axis of rotation 1 on each of its side walls 1b, which axes are coaxial with each other .
- These axes 4 are generally perpendicular to the longitudinal plane of symmetry of the helmet.
- the screen 2 is also formed of a curved plate of polycarbonate about 2 mm thick obtained by molding. It is rotatably mounted about the aforementioned axes of rotation 4.
- Figure 3 shows a schematic configuration where the chinrest 3 is in the closed position and the screen 2 in the folded position.
- the screen 2 is maintained - at its outer wall 21, by an inner rim 31 of the chinrest 3.
- This inner rim 31 is generally provided with a seal 32, is presenting for example in the form of a deformable rubber band.
- the screen 2 is further maintained by an abutment member 5 arranged on the chinrest 3. In closed position with screen 2 folded, the latter is thus maintained in position between two opposite supports, which limits or eliminates any penetration phenomenon and helps to maintain an optimal seal. The risks possible air leakage due to deformation of the screen 2 are therefore perfectly controlled.
- the stop member 5 is in the form of a lever 50 made of metal, carbon or plastic (eg ABS).
- This lever 50 is rotatably mounted on a pivot axis movable between a locking position where it bears against the inner wall 22 of the screen 2 (FIG. 3) and a retracted position where it releases the said inner wall (FIG. ), that is to say that he is no longer in contact with the latter.
- the abutment member 5 may, however, be in other forms, and for example consist of several parts hinged together to provide the same functions.
- the lever 50 is rotatably mounted about a horizontal axis 51, which axis is integral with the chinrest 3.
- This lever 50 comprises a lower portion 52 forming a maneuvering member and an upper portion 53 forming a stop.

In practice, this lower portion 52 is located at the front of the chinrest 3, which, in use, is vis-à-vis the chin of the user.
- the chinrest 3 comprises for this purpose a housing 300 in which the lower portion 52 is housed so that it is perfectly integrated into the shell of said chin guard. This housing 300, however, allows easy grip of the lower part 52 by the fingers of the user.
- the upper portion 53 forming an abutment is located opposite the lower part 52.
- This upper part 53 is provided with a spout, which, when the lever 50 is in the locking position, comes block the inner face 122 of the screen 2, at the lower end thereof.
- the upper part 53 may optionally be provided with a deformable seal similar to the seal 32.
- a biasing member 54 maintains the lever 50 in the locked position and automatically returns to this position when in the retracted position.
- this member 54 is in the form of a tension spring or torsion, one end of which is fixed to the chinrest 3 and the other end is fixed to the lever 50, in the locking position, this member 54 constrains the screen 2 against the inner rim 31 of the chinrest 3, thereby improving the retention in position of said screen and the seal.
- this member 54 constrains the screen 2 against the inner rim 31 of the chinrest 3, thereby improving the retention in position of said screen and the seal.
- its constraints on the screen 2 are such that the user always has the opportunity to easily raise said screen in the retracted position.
- the passage of the stop member 5 from the locking position to the retracted position is very simple. As illustrated in FIG.
- the chinrest 3 is mounted to move in translation on the side walls 1b of shell 1 so as to slide towards the front of said helmet, from a retracted position (FIG. 3) where it forms with It has an integral helmet and an advanced position ( Figure 5) where it can pivot to the open position.
- the side branches 33 are slidably mounted on intermediate parts 63, which parts are mounted to rotate on the side walls 1b of shell 1, about the axes 4.
- Each distended end 330 of the lateral branches 33 of the chinrest 3 is integral with a slider 60, which slider can be made in metal or plastic.
- This slider 60 is fixed on the inner wall of the end 330 by means of screws 61a and nuts 61b. In an alternative embodiment, it is conceivable to fix the slide 60 not at the distal end 330, but further offset from the axis of rotation 4. for example in the middle of the lateral branch 33.
- the slider 60 is slidably mounted in a rail 62 arranged on an intermediate piece 63.
- the rail 62 may be attached or be an integral part of the latter. In the accompanying figures, it is in the form of an oblong hole.
- An intermediate piece 63 is provided at each side wall 1b of the shell 1.
- This intermediate piece 63 is for example in the form of a plate whose shape substantially corresponds to that of the end 330.
- the part 33 is advantageously made of polycarbonate about 1 mm thick and obtained by molding to integrate directly rail 62.
- the latter is rectilinear and oriented in the same direction as the side branch 33 3 said rail is attached.
- the intermediate piece 63 is rotatably mounted on the side wall 1b of the shell 1. Referring to FIG. 6, its intermediate piece 63 is rotatably mounted about the axis 4, which axis is integral with the shell 1.
- the free end of the axis 4 advantageously comprises a shoulder, or a pin, whose function is to block the translation of the part 83 along said axis.
- the chinrest 3 is not mounted directly mobile in rotation about the axes 4. It is slidably mounted on the intermediate parts 63, which are pivotally mounted on the shell 1, at the axes 4. Such articulation is simple to make and less complex than those described in the patent documents EP 0.993.784 (MOTIVE), EP 1.887.898 (ROOF) or FR 2.876.882 (SHARK) cited above.
- covers 84, 65 are clipped preferentially on the outer wall of the chin guard 3 to conceal certain elements of the joint, and in particular the axis 4, the screws 61a and the bolts 81b.
- a biasing member is arranged to constrain the chinrest 3 to the advanced position.
- a tension spring 66 is installed in the rail 62 so as to push or pull the slide 60 forward of said rail.
- a retaining member 7 mounted movably between a locking position ( Figures 3, 3a and 7) where it holds the chinrest 3 in the retracted position and a retracted position ( Figures 4, 4a and 5) where it releases said chinrest so that, under the action of the biasing member 68, it can automatically slide to the advanced position.
- this retaining member 7 is in the form of a lever 70 made of metal, carbon or plastic (eg ABS).
- This lever 70 is mounted rotatably about a horizontal axis 71. The latter is secured to the chinrest 3 and fixed at its end 330.
- the lever 70 comprises a beak-shaped portion 72 which, when said lever is in the locking position (FIG. 3a), is hooked on an abutment 73 integral with the intermediate piece 63.
- the spout 72 disengages from the stop 73 ( Figure 4a)
- the spring 66 then pushes the chinrest 3 towards the front of the helmet ( Figure 5).
- the abutment member 5 must be in the retracted position so as not to impede this translational movement of the chinrest 3. According to another embodiment, it is possible to eliminate the stop member 5.
- a biasing member 74 maintains the lever 70 in the locking position and automatically return to this position when in the retracted position.
- this member 74 is in the form of a spring, traction or torsion, one end 74a is fixed to the chinrest 3 and the other end 74b is fixed to the lever 70.
- a maneuvering member makes it possible to move the chin guard 3 from the retracted position to the advanced position.
- this operating member acts on the retaining member 7 by tilting the lever 70 to the retracted position.
- the lever 70 may for example be provided with a trigger-shaped portion accessible at the side branch of the chinrest 3.
- This trigger when pushed or pulled by the user, allows the lever 70 to be pivoted. around the axis 71 so as to disengage the spout 72 of the abutment 73.
- This operating member is in this case specific to the lever 70 and completely independent of the operating member 52 described above and associated with the stop member 5.
- the translational movement of the chinrest 3 is preferably controlled by the retraction of the abutment member 5.
- the actuation of the stop member 5 induces the actuation of the chinrest 3 and vice versa.
- the same operating member can act simultaneously on the retaining member 7 and on the stop member 5,
- a link 8 connects the retaining member 7 to the abutment member 5.
- This connection may for example be in the form of a wire rope of about 1 mm in diameter, slidably mounted in guides 9 arranged in the chinrest 3,
- the link 8 comprises an end 8a fixed on the lever 50 and another end 8b fixed on the lever 70.
- the attachment points of the link 8 are arranged so that the tilting of the lever 50 about the axis 51 causes the tilting the lever 70 about the axis 71.
- the lever 50 pivots about the axis 51 by pulling the link 8. This traction causes the lever 70 to tilt. around the axis 71 and unlocking the stop 73.
- the mechanism for actuating the abutment member 5 can be applied to helmets devoid of chinrest 3 movable in translation and / or helmets described in the aforementioned patent documents: EP 0.993.784 (MOTIVE), EP 1.887. 898 (ROOF), FR 2.876.882 (SH ⁇ RK).
- the mechanism for initiating the sliding translation of the chinrest 3 can be applied perfectly to helmets without abutment member 5.
