Definitions

• the present invention relates generally to helmets for use in various situations and environments, and in particular to a protective helmet equipped with a movable ocular screen and an ocular screen.
• a helmet typically includes a shell for protecting the head that has a facial opening opposite the face of the wearer, and an ocular screen that is placed in front of the eyes.
• the ocular screen is generally movably mounted relative to the shell between a low position, in which the screen extends opposite the facial opening, and a high position, in which the facial opening is substantially clear.
• the wearer can place the screen in the high position when the circumstances do not require the protection of the eyes, or when the user would like to remove the helmet.
• the screen can be lowered when the user's eyes should be protected.
• the system for assembling the screen on the shell has disadvantages and requires improvement.
• these operations of mounting (i.e., attaching) and dismounting (i.e., detaching) the screen most often require tools, time, and a certain experience in this field. In some instances, removing the helmet may even be necessary in order to remove the screen, or replace it with another one. Therefore, these operations, which are carried out in the case of the fireman by the technical department of the fire station, are constraining, in particular in terms of the time. Furthermore, the recourse to tools entails a risk of damaging the removed screen (which may be reusable) and/or damaging the new screen to be put in place.
• the studs extend outside of the shell, which is required for allowing a user to unlock and remove the ocular screen.
• This existing arrangement results in the possibility that the accidental disengagement of the studs outside of the shell openings can occur, especially if an object falls on the helmet and comes to press on a stud.
• a protective helmet and ocular screen that address and/or overcome some or all of the potential drawbacks associated with existing protective helmets utilizing or including ocular screens and similar arrangements.
• a protective helmet including: a structure including: an outer shell intended to surround the head of a user and presenting a facial opening; and an inner module fixed in the shell and including a cap and a ring mounted in the lower part of the cap; an ocular screen assembled to the structure in a detachable manner and which can move between a low position in which the screen extends opposite the facial opening and a high position in which the facial opening is substantially clear, which screen includes a central part and two lateral wings; and a leg mounted on each lateral wing of the screen in such a manner that it can rotate about a substantially transversal axis in order to permit the pivoting of the screen between its high and low positions, whereby each leg is intended to be engaged in a corresponding housing arranged in the ring for the assembly of the screen to the structure, at least one leg including a locking means or locking arrangement for locking onto the structure, which is integrally situated inside the shell in the position of use, and which can be deactivated by a
• this embodiment provides a helmet and system for mounting the screen that is simple and easy to implement without tools, such as through the use of two legs, each one inserted in a housing, which legs are locked to the structure.
• the locking means or locking arrangement can be unlocked manually by the user when so desired.
• a significant advantage of the present invention is that the shell retains its integrity since, in this embodiment, the screen is fixed on the ring of the inner module, as opposed to an opening on the shell itself.
• each of the two legs includes a locking means or locking arrangement for locking on the structure, where the helmet unit generally presents a longitudinal symmetrical plane.
• the shell includes an anchoring device on its inner face and configured for cooperation with the locking arrangement or locking means arranged on the leg, or on each leg. In this manner, the leg is locked on the shell.
• This embodiment is advantageous in that it facilitates excellent fixation or attachment. Furthermore, securing the leg onto the shell contributes to a better hold of the various components of the helmet between them, and therefore to the overall integrity of the helmet.
• the locking means comprise an opening arranged on the leg and the anchoring device comprises a pin projecting from a lateral part of the shell toward the interior. Said opening typically opens transversally towards the pin, and can pass transversally through the leg.
• the opening arranged on the leg comprises a hook, i.e. an opening having an aperture, for example a substantially radial aperture.
• the pin includes a shaft and an enlarged head
• the hook includes a zone or area for the reception and retention of the pin. This zone or area may be in the form of an opening that has, at rest, a diameter less than the diameter of the pin shaft, and which can be enlarged by elastic deformation by the action of a user in order to permit the introduction of the pin into the hook, and to prevent the accidental removal or disengagement of the pin from of the hook.
• the hook is arranged substantially parallel to a lateral part of the shell and is open to the front.
• the opening arranged on the leg comprises a hole having a closed contour.
• the leg includes a positioning arrangement including at least one positioning member suitable for cooperating by friction with the housing arranged in the ring.
• the positioning arrangement has the function of permitting adjustment of the leg in the housing before locking. This temporary retention during the mounting may not be sufficient, itself, during use, such that sufficient locking occurs through use of the shell. Accordingly, in one embodiment, the positioning arrangement does not implement the function of locking.
• this positioning arrangement also acts as a guide for the introduction of the leg into the housing.
• a positioning member projects from the leg body and is suitable for cooperating with one face of the housing. It can be configured to project substantially radially from the leg body. In this manner, only this positioning member is in contact with the housing, which allows the rubbing surface to be limited, and therefore, the force necessary for the introduction of the leg into the housing.
• the positioning member is formed by the leg body itself. Thus, the entire leg would be in contact with the housing.
• a wall of the housing (e.g., a lateral wall of the housing) includes a notch with a form complementary to that of the positioning member. Therefore, the positioning member interacts with the notch and cooperates with friction with the edges of the notch. As a result, the positioning member guides the movement and introduction of the leg into the housing, and also ensures a temporary holding of the leg in the housing.
• the positioning member forms a localized excess thickness configured for cooperating with an internal face of the housing.
• the leg body can include a thickness less than the internal dimension of the housing in order to facilitate the insertion of the leg, and the positioning member locally creates a small hard point that generates friction.
• the leg includes a catch for cooperating (by clipping) with a wall of the housing in order to facilitate the locking of the leg on the structure. Accordingly, the leg locks onto the ring.
• One advantage of this embodiment is that it beneficially uses the ring, which already acts as support for the fixation of numerous elements of the helmet, such as the cap, the headband, and the chin strap. Therefore, the function of protection (ensured by the shell) and the functions of support/fixation (ensured by the ring) are separated and/or disassociated. Further, unlocking may occur by simply pulling on the leg with a force sufficient to release the clipping. Accordingly, no other means for locking the leg to the structure is provided.
• the catch is not a simple positioning member, but facilitates a locking function. It therefore has to be adequately dimensioned, to be big enough to provide an efficient locking effect, but to allow a user to detach the screen, possibly but not necessarily using an unlocking system provided, for example, on the helmet.
• Another advantage of this embodiment is that it makes it possible to provide an efficient locking effect while being extremely compact, specifically in the transverse direction.
• the catch can protrude inward from the leg, which is advantageous in terms of safety insofar as the catch is not accessible from outside the shell.
• the housing is open at the bottom, in the position of use, in order to permit the introduction of the leg in an ascending movement, and the catch projects from the leg body and is arranged to be placed above a wall of the housing.
• a clipping function is provided at the end of the ascending movement of the mounting of the screen, whereas for release of the locking, the leg is pulled downward.
• the housing includes an opening arranged in one of its lateral walls, and the catch is configured for placement above an edge of this opening.
• the housing does not include an opening, and clipping instead occurs above the upper edge of the housing.
• the housing includes a conduit with a substantially vertical axis that has an open lower end situated in the lower wall of the ring, in order to allow the introduction of the leg from the bottom towards the top, in the position of use.
• a protective helmet including: an outer shell defining a facial opening; an ocular screen removably attached to the outer shell and configured to move between a low position in which the screen extends opposite the facial opening and a high position in which the facial opening is substantially clear, wherein the screen has a central part and two lateral wings; and a leg rotatably mounted on each lateral wing of the screen to facilitate pivoting of the screen between the high position and the low position, wherein each leg is engageable in a corresponding housing for attachment of the screen to the outer shell, and wherein at least one leg includes a locking arrangement configured to be deactivated by a manual action of the user.
• a protective helmet including: a structure including an outer shell defining a facial opening, and an inner module fixed in the outer shell and including a cap and a ring mounted in a lower part of the cap; an ocular screen assembled to the structure in a detachable manner and configured to move between a low position, in which the screen extends opposite the facial opening and a high position, in which the facial opening is substantially clear, wherein the screen includes a central part and two lateral wings; and a leg mounted on each lateral wing of the screen, such that each leg can rotate about a substantially transversal axis in order to permit the pivoting of the screen between its high and low positions, wherein each is engageable in a corresponding housing arranged in the ring for the assembly of the screen to the structure, and at least one leg includes a locking arrangement on the structure and integrally positioned inside the shell, in the position of use, and configured to be deactivated by a manual action of the user.

• the shell 2 is intended to surround the head of a user and is constructed, for example, from a composite or thermoplastic material.
• the shell 2 has a longitudinal plane of symmetry P (X, Z).

• Each lateral part 8 may include a recess 9 towards the interior.
• a plate 10 is fixed on each lateral part 8 of the shell 2 in such a manner as to cover at least a part of this recess 9.
• the plates 10 are substantially flush with the zones or areas of the helmet 1 situated around the recess 9, such that the shell 2 has in this zone or area an outer surface that is substantially without a discontinuity.
• the plate 10 can also serve for hooking on a device for connecting a breathing mask.
• the inner module includes a cap 11 that allows shocks to be absorbed and which is, for example, constructed from compact foam.
• the cap 11 preferably includes a curved form and a substantially oval lower part 12.
• the inner module also includes a ring 15 mounted in the lower part of the cap 11. As Fig. 2 illustrates, the ring 15 has a substantially oval form that is similar to that of the lower part of the cap 11. Further, in this embodiment, the ring 15 includes a section in the form of a "U" in which the lower part 12 of the cap 11 is mounted.
• the inner module may also include a lining for the comfort of the wearer, an adjustable headband, and a chin strap (not shown), all preferably mounted on the ring 15.
• the ring 15 supports various components of the helmet 1, and includes or forms the arrangement for fixing the inner module in the shell 2 in a removable manner.
• the ring 15 includes an outer wall 16 and an inner wall 17 that are substantially oval, parallel, and connected by a lower wall 18 forming the bottom of the U-shaped section of the ring 15.

• the outer wall 16 includes, in front of the zone or area of the ring 15 where the cavity 22 and the housing 25 are located, a part 14 that is substantially planar and longitudinal and forms a set-back toward the interior relative to the continuity of the oval form of the rest of this outer wall 16.
• the cavity 22 is preferably situated behind the housing 25 in order to avoid impeding the pivoting of the screen 3.
• the cavity 22 is presented, for example, in the form of a conduit extending in the direction Y, open at its outer end, and including lower front and rear returns 27, 28 that facilitate the retention of the fixation member 23.
• This fixation member 23, illustrated in one preferred and non-limiting embodiment in Fig. 5, is substantially in the shape of an "L" with a horizontal branch 29 and a vertical branch 30, in the position of use.
• the branch 29 In order to mount the ring 15 on the shell 2, the branch 29 is engaged in the cavity 22, and a blocking arrangement or member for blocking in position can be provided, such as a notching system.
• the branch 30 In the mounted position, the branch 30 is oriented downward and substantially parallel to the corresponding lateral part 8 of the shell 2.
• a hole 31 arranged in the branch 30 is engaged around a substantially cylindrical stud 32 projecting transversally toward the inside of the corresponding lateral part 8 of the shell 2, as Fig. 6 shows.
• Fixing of the ring 15 in the shell 2 is, for example, implemented through the use of hooks 33 positioned behind the ring 15 and clipped onto rods 34 arranged in the rear part 7 of the shell. It is envisioned that other arrangements can be used to fix the ring 15 on the shell 2.
• the housing 25 includes a conduit with a substantially vertical axis that includes a transversal section, i.e., in the plane (X, Y), and which is substantially rectangular.
• This conduit has four lateral walls, including: an outer wall 35 that is substantially planar and merged with the outer wall 16 of the ring 15; an inner wall 36 that is substantially planar and parallel to the outer wall 35, situated between the outer wall 16 and the inner wall 17 of the ring 15; a front wall 37 that is substantially orthogonal to the outer wall 35 and the inner wall 36, and that has an upper part 38 inclined toward the inside of the housing 25, i.e., to the rear; and a rear wall 39 that is substantially orthogonal to the outer wall 35 and to the inner wall 36, and which may also constitute the front wall of the cavity 22.

• this notch could have other shapes, such as a rectangular shape.
• this screen 3 has a longitudinal plane of symmetry that is substantially merged with the plane P in the mounted position of the helmet 1.
• the screen 3 includes a central part 45 through which the wearer can see his or her environment and has two lateral wings 46 that permit the mounting of the screen 3 on the structure.
• the lateral wings 46 and the central part 45 are formed in one piece, whereas, in the first embodiment (and with specific reference to Figs. 1 and 8-11), each lateral wing 46 is formed in part by a lateral prolongation 47 of the central part 45 and by an intermediate piece 48 articulated on this prolongation 47.
• An intermediate piece 48 includes an arrangement or structure that facilitates an approach to the face of the user when the screen 3 is in the low position. This provides improved protection of the user's face since the space existing between the face and the screen 3 is reduced, which significantly limits the potential entrance of elements underneath the screen 3. Further, if the user is wearing glasses that limit the ability of the screen 3 to approach the user's face, he or she can keep the screen in the position at a distance from their face. Accordingly, the presently-invented helmet 1 can be used by a person wearing such glasses.
• a leg 26 is mounted on each lateral wing 46 of the screen 3 and is configured for engagement in the corresponding housing 25 arranged in the ring 15 for the assembly of the screen 3 to the structure.
• the leg 26 is mounted on the wing 46 in such a manner that it can move in rotation about a substantially transversal axis 44 in the position of use. Accordingly, the screen 3 can pivot relative to the structure of the helmet 1 between a low position, in which the screen 3 extends opposite the facial opening 4 in front of the eyes of the user, and a high position, in which the facial opening 4 is substantially clear.
• the screen 3, the leg 26, and/or the ring 15 includes a stop that limits the upward and downward course of pivoting of the screen.
• the leg 26 has a body that is generally planar and rectangular, with an upper part having a geometry that allows it to come into engagement in the housing 25 of the ring 15. In this embodiment, the leg 26 is introduced from below upward through the lower open end 40 of the housing 25. Thus, in the position of use, the leg 26 extends substantially in a plane (X, Z).
• the leg includes a hole 49 in the leg 26, for example, in the central part of the leg 26.
• the hole 49 is clipped into a bush 50 projecting from the corresponding lateral wing 46 of the screen 3 radially toward the inside (see, for example, Fig. 1 1).
• the bush 50 has, for example, axial slots and a radial end collar, which allows for the mounting and the retention of the leg 26 by elastic deformation of the bush 50, as well as the rotation of the leg 26 about the axis 44 of the bush 50.
• Various arrangements and structures can be used for providing the rotary mounting of the leg 26 on the screen 3.
• At least one leg and, preferably, both legs 26 include a locking arrangement, member, or means for connecting to the structure of the helmet 1. Therefore, the legs 26 facilitate both the mounting of the screen 3 on the structure and locking in the mounted position (where the screen 3 still retains its ability to be raised and lowered).
• the locking arrangement or connecting member is positioned or situated partially or wholly inside the shell 2 in the position of use, and can be deactivated by a manual action of the user.
• each pin 51 includes a shaft and an enlarged head, i.e., extends beyond the shaft in the direction radial to the shaft.
• the leg 26 has a hook 52, for example, at its lower end, which includes or forms a tongue 53.
• the hook 52 has a zone or area 54 for receiving the pin 51 and retaining the pin 51 when it is put in place in the hook 52.
• the reception zone or area 54 includes a dimension between that of the shaft and that of the head of the pin 51.
• the hook 52 has an opening 55 defined between the tongue 53 and the remainder of the leg 26 through which a user can pass the pin 51 up to the receiving zone or area 54 in order to lock onto the shell 2.
• the opening 55 has, at rest, a dimension that is less than the diameter of the shaft of the pin 51 in such a manner as to prevent the accidental disengagement or removal of the pin 51 from the hook 52.
• the introduction of the pin 51 into the hook 52 is facilitated by the elasticity of the hook 52, and the tongue 53 can deform in order to permit the enlarging of the opening 55.
• the pin 51 can exit through the opening 55 for unlocking under the action of a user.
• a pull on the hook 52 is sufficient to enlarge the opening 55 by the passage of the shaft of the pin 51, and, thereby, unlock the leg 26 of the structure in order to be able to remove the screen 3.
• the hook 52 is arranged substantially parallel to a lateral part 8 of the shell 2 and is open to the front.
• the leg 26 is provided with a positioning member for cooperating, by friction, with the housing 25 in order to permit a temporary holding of the leg 26 in the housing.
• the leg 26 includes a positioning arrangement including a first positioning member 56 and, optionally, a second positioning member 57.
• the first positioning member 56 that projects from the body of the leg 26 toward the outside above the hole 49.
• This first positioning member 56 has a shape complementary to that of the notch 42, such that, in this embodiment, two fingers are illustrated.
• other shapes can be utilized, such as a substantially rectangular shape.
• providing a notch shape that is different on the left and on the right can serve as a means of avoiding a mistake in order to avoid an erroneous mounting.
• the first positioning member 56 facilitates the guidance for introduction of the leg 26 into the housing 25. Furthermore, due to its geometry (i.e., a shape slightly widened upward and/or other specifically-configured dimensions), the first positioning member 56 cooperates, by friction, with the edges of the notch 42, thereby ensuring a certain adjustment and a certain temporary retention of the leg 26 in the ring 15, minimizing or eliminating the possibility that the leg 26 falls out before or during the operation of locking.
• a second positioning member 57 is provided in the form of a small tooth projecting toward the inside and/or toward the outside of the body of the leg 26.
• This tooth 57 forms a localized excess thickness suitable for operating with an inner face of the housing 25. Therefore, as opposed to facilitating the locking of the leg 26 in the housing 25, this second positioning member provides for certain adjustability. Therefore, in this embodiment, the tooth 57 need not extend above the housing 25 in order to find support on the upper edge thereof.
• the body of the leg 26, itself can be configured to the inner shape and dimensions of the housing 25. Therefore, the front edge 58 and the rear edge 59 of the leg 26 can come in direct or indirect contact against the front wall 37 and rear wall 39 of the housing 25.
• an upper end part 60 of the leg 26 is provided and substantially triangular in shape, so as to be adapted to the upper inclined part 38 of the front wall 37 of the housing 25.
• the leg 26 extends above the housing 25 in the mounted position.
• the leg 26 includes a catch 61 that permits clipping of the leg 26 on the ring 15.
• the catch 61 projects from the body of the leg 26 toward the inside. Therefore, the catch 61 is not a simple positioning member, but also facilitates locking.
• the catch 61 has a more significant radial dimension, which permits a clipping (as opposed to an adjustment by friction). Therefore, in this second embodiment, a user should pull more strongly on the leg 26 in order to remove it from the housing 25, whereas in the first embodiment, the force of traction must occur at the level of the hook 52 (and not at the level of the tooth 57).
• the housing 25 has an opening 62 arranged in its inner wall 36, which opening 62 can open towards the top.
• the catch 61 is designed to be able to be placed in the opening 62, and therefore is positioned or located above a substantially horizontal wall 63 in such a manner as to ensure the locking of the leg 26.
• the shell 2 comprises an anchoring device on its inner face, which can be for example a pin 51 projecting from a lateral part 8 of the shell 2 toward the interior, as shown in Fig. 6.
• This anchoring device is intended for cooperating with the locking means or locking arrangement of the leg 26, which comprises a hole 70 having a closed contour.
• the pin 51 has to be clipped into the hole 70, for example by pushing the corresponding leg 26 transversally towards the lateral part 8 of the shell 2.
• the leg 26 may further include a second positioning member 57, which, in a preferred and non-limiting embodiment, is in the form of a small tooth projecting toward the inside and/or toward the outside of the body of the leg 26.
• This tooth 57 forms a localized excess thickness suitable for operating with an inner face of the housing 25. Therefore, as opposed to facilitating the locking of the leg 26 in the housing 25, this second positioning member provides for certain adjustability.
• the present invention provides a significant improvement over existing systems and arrangement by providing a helmet that allows the ocular screen to be rapidly and easily changed, while ensuring a satisfactory retention and locking of the screen in the mounted position. Furthermore, the screen retains its ability to be raised and lowered and the above advantages do not adversely impact safety, since the helmet confers excellent protection to the head by the integrity of its outer shell.
• Another significant of the invention is that it provides a compact attaching system, especially in the transverse direction, which frees space for housing various devices inside the shell, such as ear protections.
