Description

Title of the invention: Display module worn on the head or on a helmet.

[0001] The technical field of the invention is that of visualization systems for aircraft pilots. More specifically, the field of the invention is that of systems combining both binoculars and a sight or head-mounted display.

[0002] A viewing system may include three different viewing devices: a protective visor, a head-mounted sight or display, and binoculars, which may be night vision binoculars. In the following description, the term "head-mounted display" will refer to both a helmet-mounted sight and a head-mounted display. The acronym "NVG" will also be used to refer to night vision binoculars.

[0003] Night vision binoculars capture the brightness of objects in the near-infrared and produce a visible image using image intensifiers. They consist of two identical bodies. Each body has three main parts: a lens, the image intensifier, and an eyepiece. The field of view of the NVGs through the eyepiece typically has a diameter of 40 degrees. To see the entire intensified image, the NVG eyepiece is usually positioned approximately 25 millimeters from the eye.

[0004] A head-mounted display presents a synthetic image or video collimated at infinity, superimposed on the outside by means of a projection lens and an optical combiner or mixer. The image generally comes from a flat screen comprising a light source and its electronic control board. The projection lens ensures the collimation of the image displayed in the combiner. To reduce the dimensions of this element, pupil-expanding combiners are used. The combiner is then an optical plate made up of a plurality of prisms reflecting the light from the synthetic image towards the eye.

[0005] Currently, some surveillance missions do not necessarily require the use of a rigid protective helmet, and a simple, lighter headband or headband can be used to relieve the operator's head of the weight of the protective helmet. For example, in the case of a maritime surveillance mission, which may last several hours, during which an operator is on board an airplane, helicopter, or any other aircraft, and spends a considerable amount of time observing the sea surface, the crew, including the operator, is equipped only with a rigid headband or headband to avoid wearing a heavy protective helmet.

[0006] In order to support the operator in his monitoring, a display device for the in Night vision goggles (NVGs) can be attached to a headband or head strap to display essential information for conducting a surveillance mission. However, NVGs are too heavy and bulky to be mounted on a headband or head strap and are generally attached to rigid protective helmets. Furthermore, aircraft and flight condition information is usually displayed on screens in the cockpit or cabin.

[0007] Therefore, when night falls, the operator must replace the headband or head strap with a protective helmet to continue night monitoring. However, this requires the operator to lower their head towards the cockpit screens to obtain essential information about their surroundings, the aircraft, etc. Alternating between monitoring the external environment and observing the cockpit screens, which necessitates the operator lowering their head, impairs their situational awareness by reducing the time they spend monitoring the external environment. Furthermore, this alternation also greatly fatigues the operator, which also hinders the effective performance of their monitoring mission.

[0008] In addition to nighttime conditions, any variation in brightness may necessitate replacing the display device with binoculars or vice versa. Similarly, the topography and geography of the environment may require the operator, during monitoring, to replace the display device with binoculars or vice versa. Indeed, when the ground environment is a uniform expanse, a display device seems sufficient. However, when terrain is visible on the ground, binoculars appear more appropriate, and replacing the display device and headband with binoculars and the helmet that supports them may be necessary.

[0009] Consequently, the replacement of the headband or rigid band supporting the display device with the helmet supporting the binoculars (NVG or other) and vice versa occurs at least once, and very often several times, during the operator's monitoring. These multiple changes represent a significant amount of time during which the operator cannot perform their monitoring. These multiple changes also generate additional fatigue for the operator during monitoring that can last a long time.

[0010] In addition, the combined use of a headband or headband for the day and a helmet with NVGs at night greatly increases the clutter at the operator's station.

[0011] The invention aims to overcome all or part of the problems mentioned above by offering a removable helmet visual with compatible fixings for mounting on a helmet or headband and of a volume compatible with binoculars.

[0012] More specifically, the invention therefore proposes a visualization system comprising removable visualization equipment such as a display device or NVs that can be attached to a rigid protective helmet or to a rigid headband or headband.

[0013] To this end, the invention relates to a visualization system intended to cooperate with a cranial support, said visualization system comprising: - a detachable display device, comprising: • a combiner, positioned in front of the user's eye, capable of presenting information superimposed on an external view, the display system including a removable mounting interface, configured to associate the display device with a plurality of cranial supports including at least one helmet, headband and headband.

[0014] According to one aspect of the invention, the detachable display device includes a binocular support attachment interface, the viewing system includes detachable binoculars, the binoculars include a binocular support, suitable for being fixed against the display device by mechanical association of the binocular support attachment interface and the binocular support so that the display device is located between the user's eye and the binoculars.

[0015] According to one aspect of the invention, the removable mounting interface comprises: - a first fixing system mounted on the removable mounting interface, - a second fixing system complementary to the first fixing system, mounted on the cranial support, the first fixing system being configured to be associated with the second fixing system so as to embed the first fixing system.

[0016] According to one aspect of the invention, the first fastening system comprises a slide system and the second fastening system comprises a T-groove.

[0017] According to one aspect of the invention, the slide system includes a notching device and the T-slot includes a ball pusher system.

[0018] According to one aspect of the invention, the T-groove is mobile in rotation about a transverse axis, one component of which is perpendicular to a visual field of the user.

[0019] According to one aspect of the invention, the second fastening system is mobile in rotation about a second axis parallel to the user's field of vision.

[0020] According to one aspect of the invention, the system is intended to be associated with a helmet, the helmet comprising an adapter plate connected to the second fixing system and to the binocular support fixing interface, the display device and the binoculars being movable in translation relative to the helmet's adapter plate along a vertical axis perpendicular to the transverse axis and to the second visual field axis.

[0021] According to one aspect of the invention, the display device comprises a first pole of magnets, the viewing system comprises a movable visor, the movable visor includes a second pole of magnets complementary to the first pole of magnets, magnetically connected to the first pole of magnets so as to keep the movable visor in contact with the display device.

[0022] According to one aspect of the invention, the removable mounting interface comprises: - a first fastening system mounted on the removable mounting interface, - a second fastening system, complementary to the first fastening system, intended to be mounted on the cranial support, the first fixing system being configured to be associated with the second fixing system so as to embed the first fixing system, the display system being intended to be associated with a helmet, the helmet comprising an adapter plate connected to the second fixing system of the display device, the removable visor comprising a fixing plate connected to the adapter plate of the helmet.

[0023] According to one aspect of the invention, the binoculars are night vision binoculars comprising two identical bodies, each body comprising an eyepiece.

[0024] According to one aspect of the invention, the display device comprises a flat display screen, its light source, collimation optics and an optical pupil expansion combiner.

[0025] The invention will be better understood and other advantages will become apparent upon reading the detailed description of an embodiment given by way of example, a description illustrated by the accompanying drawing in which:

[0035] For the sake of clarity, the same elements will bear the same references in the different figures.

[0036] Figure 1 represents a display system 2 according to the invention intended to cooperate with a cranial support 4. The cranial support 4 is defined as a support comprising a rigid frame that rests on the skull of a user. By way of example, the cranial support 4 is a protective helmet, a headband, or a headband. In the following description of Figure 1, the cranial support 4 is a headband. The display system 2 includes a display device 6 detachable from the cranial support 4. The display device 6 includes a combiner 60, positioned in front of one eye 8 of the user wearing the cranial support 4 and the display system 2. The combiner 60 is capable of presenting information in front of the eye 8 superimposed on external vision.

[0037] The display system 2 also includes a removable mounting interface 10, configured to associate the display device 6 with a plurality of cranial supports 4, including at least one helmet, headband, and headband. Preferably, the cranial support 4, and particularly the headband and headband, is a rigid support, i.e., the structure of the cranial support 4 is rigid enough to support at least the display device 6 and other visual equipment. Thus, the cranial support can be any other support resting on the operator's skull and having sufficient rigidity to support visual equipment. Indeed, the display system 2 has the advantage of being able to be associated with a headband or headband as shown in [Fig.[l] and, when night falls, to be detached from the cranial support 4 used, namely the headband, and then to be attached to another cranial support 4, of a different structure than the headband, such as a helmet, shown in [Fig. 2], equipped with NVGs allowing the operator to observe at night. Thus, the visual equipment, namely the display device 6, is detachable and compatible with all the cranial supports worn by the operator so as to allow the operator not to be encumbered with several identical visual equipment on different cranial supports.

[0038] Therefore, the operator has at his disposal a mounting means, namely the removable mounting interface 10, allowing the display device 6 to be mounted on a helmet or on a headband and allowing switching from a headband or headband to a helmet in flight.

[0039] The headband 4 optionally includes a strap 3 connecting a front face 40 of the headband 4 to a rear face 42 of the headband 4 so as to improve the positioning of the headband 4 on the operator's skull.

[0040] The headband 4 also includes a weighting means 44 for the headband 4 positioned at the back of the operator's skull relative to his field of vision allowing to compensate for the weight at the front of the headband 4 caused by the positioning of the display device 6 and thus achieve balance on the operator's head. Therefore, the mass of the weighting device 44 is at least equivalent to the mass of the display device 6. As an indicative example, the weighting device 44 has a mass of approximately 200 grams.

[0041] Furthermore, the weighting means 44 also serves as an adjustment means for the headband 4 to adapt it to the shape of the head. The support at the nape of the neck contributes to the stability and support of the entire headband 4 on the head. The headband 4 is weighted to compensate for the mass installed at the front.

[0042] The display device 6 includes a flat display screen, its light source and control electronics 68, collimation optics 62, an imager 64 integrating the light source and the pupil-expanding optical combiner 60.

[0043] The collimation optics 62 and the imager 64 are located in the lower part of the display device 6 and the control electronics 68 are positioned in the upper part of the display device 6.

[0044] The display device includes, according to one variant, a position sensor 69 located in the upper part allowing the correct positioning of the display device 6 to be detected.

[0045] The direct connection between the display device 6 and the position sensor 69 thus offers the advantage of real-time and automatic positioning of the display device 6 to perfectly match the operator's field of vision. In other words, the display device 6, including the position sensor 69, does not require realignment of the display to the sensor data after in-flight data exchange.

[0046] The detachable display device 6 also includes a binocular support attachment interface 61, shown in [Fig. 2] (and more specifically in [Fig. 3]). Indeed, when night falls, the operator must remove the headband in order to change the head support 4 to use binoculars 7. Therefore, the head support 4 becomes, in the case of the description in [Fig. 2], a protective helmet 4. The viewing system 2 then includes binoculars 7, such as detachable night vision goggles or NVGs, associated with the helmet 4. The binoculars 7 include a binocular holder 71, adapted to be fixed against the display device 6 by mechanical association of the binocular support interface 61 and the binocular holder 71 so that the display device 6 is positioned between one of the operator's eyes 8 and the binoculars 7.Thus, the display device 6 is fixed against the helmet 4, via the removable mounting interface 10, so that the combiner 60 presents information in front of the operator's eye 8 in superposition. with an external view provided via binoculars 7, fixed against the display device 6.

[0047] Other types of binoculars can be considered instead of night vision goggles. The binoculars 7 comprise two identical bodies, each body containing an eyepiece 72. More precisely, when the binoculars 7 are night vision goggles, each binocular body comprises, in this order, an objective lens, a light-amplifying device for the image produced by the objective lens, and the eyepiece 72, which forms an image at infinity from the intensified image. The binoculars 7 are mounted with the eyepiece 72 in contact with the combiner 60 to maintain the distance allowing the eye to see the entire field of view of the intensified image. "In contact" means that the binoculars 7 are as close as possible to the combiner 60; direct contact is not required. The binoculars 7 are adjusted laterally in front of the eye using their inter-eye adjustment mechanism and are positioned vertically in the center of the usable portion of the combiner 60 by the binocular mount 71.

[0048] To increase the available space between the headset 4 and the binoculars 7, adjustments to the binoculars can be made, such as a longitudinal adjustment of the binoculars 7 to allow the binoculars 7 and the binocular support 71 to be offset along a second axis A2 parallel to the operator's field of vision. A vertical adjustment of the binoculars can also be made, allowing them to be offset along a vertical axis A1, perpendicular to the second visual field axis A2, or an adjustment can be made around a third transverse axis A3 perpendicular to the second visual field axis A2 (or with a component perpendicular to the second visual field axis A2) and perpendicular to the vertical axis A1. The space freed up by these three adjustments thus defines the available depth for positioning the display device 6 between the operator's eye 8 and the binoculars 7.

[0049] The display device 6 is monocular and preferably positioned in front of the operator's dominant eye. Alternatively, the display device 6 is binocular, as shown in [Fig. 3], so as to advantageously present a greater amount of information to the operator. The maximum width of the display device 6, and particularly of the combiner 60, along the transverse axis A3, is defined by the installation of a display device 6 over each eye and the need to reserve a space close to the sagittal plane, the plane formed by the vertical axis A1 and the second visual field axis A2, for the binocular support mounting interface 61.

[0050] The binocular support mounting interface 61 comprises a defined number of notches 610, four notches 610 in the example of [Fig. 3], allowing the insertion of a screw head from the binocular support 71. A translation towards the combiner 60, parallel to the vertical axis A1, then allows the rusting of each screw head in the respective notches 610. The binocular support 71 is then recessed against the binocular support mounting interface 61 and thus against the display device 6. As an illustrative example, the notches 610 can be rigid buttonholes.

[0051] By way of indicative example, the binocular support attachment interface 61 may be a known attachment part of binoculars on a protective helmet.

[0052] In order to allow quick and easy attachment of the display device 6 to any cranial support 4, the removable mounting interface 10 comprises as shown in [Fig.4]: - a first fixing system 100 mounted on the removable mounting interface 10, - a second fixing system 40 complementary to the first fixing system 100, mounted on the cranial support 4, namely the helmet or the rigid headband or the rigid headband.

[0053] The first fixing system 100 is configured to be associated with the second fixing system 40 so as to embed the first fixing system 100. The first fixing system 100 and the complementary second fixing system 40 can be any male and female fixing system allowing the display device 6 to be embedded. By way of example, the first fixing system 100 can be inserted into the second fixing system 40 and locked into the second fixing system 40 by means of a third part preventing a return movement of the first fixing system 100.

[0054] More specifically, the first fixation system 100 is removable and detachable from the second complementary fixation system 40 which is, in turn, fixed against the cranial support 4.

[0055] According to a preferred configuration, represented in [Fig.4], the first fixing system 100 includes a slide system 100' and the second fixing system 40 includes a T-groove 40', of complementary dimension, allowing the sliding of the slide system.

[0056] In order to attach the display device 6 to the cranial support 4, a headband in the case shown in [Fig. 4], the slide system 100' is inserted parallel to the transverse axis A3 in the T-slot 40'. The slide system 100' also includes a notching device 110', and the T-slot 40' includes a ball plunger system 403 for securing the slide system 100' in the T-slot 40'. As shown in [Fig. 4], two ball plunger systems 403 are sufficient to lock the slide system 100'. Alternatively, more than two ball plunger systems 403 may be used. According to another embodiment, a single ball plunger 403 is sufficient to lock the system with a sufficiently stiff spring.

[0057] The second fastening system 40 also includes a visual marker 402 so as to center the slide system 100' relative to the operator's eye, the visual marker 402 being able to be aligned with visual indicators 100” present on the first fastening system 100 so as to position laterally the display device 6 relative to the operator's eye.

[0058] Furthermore, the T-shaped groove 40' is rotationally movable about the transverse axis A3, which is perpendicular to the operator's field of vision. This rotational mobility has the advantage of allowing the display device 6 to rotate and thus pivot so that the combiner 60 is no longer in front of the eye, at least partially clearing the operator's vision, during flights where the presence of the display device 6 is optional, as shown in [Fig. 5]. This rotation also has the advantage of facilitating the donning and doffing of the combiner 60 on the operator's head.

[0059] According to one embodiment, the 100' slide system is inserted parallel to the vertical axis Al into the T-slot 40', itself positioned parallel to the vertical axis Al. This configuration allows the display device to be locked in place by its own weight. However, this configuration prevents the display device 6 from pivoting, so it remains in front of the operator's eye.

[0060] Alternatively, any groove allowing insertion by sliding as well as locking of the slide can be considered.

[0061] Moreover, when the cranial support 4 is a headband or headband, as shown in [Fig.5], the height adjustment of the combiner 60 in front of the operator's eye is done by moving the cranial support 4 parallel to the vertical axis Al.

[0062] Conversely, when the cranial support 4 is a helmet, as shown in [Fig. 6], the display device 6 can also be adjusted in height in front of the operator's eye. Indeed, the display device 6, as well as the binoculars 7, are movable in translation relative to the helmet along the vertical axis A1, perpendicular to the transverse axis and to the second axis of the operator's field of vision. To achieve this, the removable mounting interface 10 includes an additional notching system 120 mounted, for example, on the second mounting system 40, allowing the height of the first mounting system 100 to be varied.

[0063] It can also be envisaged that the helmet includes an adapter plate, fixed to or integrated into the helmet, connected to the second fastening system 40 and to the binocular mounting bracket 61. In this case, the display device 6 and the binoculars 7 are also movable in translation relative to the helmet's adapter plate along the vertical axis A1. It can also be envisaged that the helmet 4 includes a headband 46 resting against the helmet 4. In this case, the adapter plate rests against the headband 46. The headband 46 is preferably made of the same material as the shell of the helmet 4. The adapter plate can be an integral part of the headband 46 or be permanently fixed to it.

[0064] Thus, the invention relates to the viewing system 2 and the cranial support 4, namely the helmet in the case of [Fig. 6], comprising the adapter plate and / or the headband 46 in which the binoculars 7, and more particularly the binocular support attachment interface 61, have translational mobility relative to the adapter plate and relative to the headband 46 and the helmet 4 along the vertical axis AL

[0065] The adapter plate is, by way of example, a known adapter plate used in the field of protective helmets in aeronautics. Similarly, the headband 46 is also a known metal headband used in the field of flight helmets. The adapter plate and the headband 46 can be formed from a single piece, as shown in [Fig. 6]. The headband can be, for example, a "Banana Bar" or "Banana Ski" headband. This headband has a surface adapted for the "permanent" attachment of the binocular holder 71 or for the binocular holder attachment interface 61 for quick mounting of the binocular holder 71.

[0066] Furthermore, the clearance of the display device 6, and particularly of the combiner 60, for example, to put on the headset 4, cannot be achieved forward, in the direction of the second visual field axis A2, due to the presence of binoculars 7 and their proximity to the headset 4. Thus, as shown in [Fig. 7], the second fastening system 40 is rotationally mobile about the operator's second visual field axis A2. More precisely, the T-slot 40' is able to pivot about a pivot 400 parallel to the second visual field axis A2, carrying the first fastening system 100 with it. Clearance is then achieved by a lateral rotation opposite to the sagittal plane, around the pivot 400, so as to move the combiner 60 away from the operator's eye and the binoculars 7.

[0067] As previously stated, since the combiner 60 is installed on the operator's dominant eye side, the pivot 400 is also installed on the dominant eye side. Alternatively, if two combiners 60 are used, two pivots 400 may be used, one pivot 400 per T-slot 40'. The pivot 400 is positioned between the headset 4 and the T-slot 40'. If the headset 4 includes a headband 46 or an adapter plate as in [Fig. 7], the pivot 400 is positioned between the adapter plate and the T-slot 40'.

[0068] Fig. 8 thus presents the visualization system 2 in which the removable mounting interface 10 includes the first fixing system 100 mounted on the removable mounting interface 10 and the second fixing system 40 complementary to the first fixing system 100, itself embedded in the second fixing system 40, mounted this time on the hoop 46.

[0069] When the display system 2 is intended to be associated with a helmet 4 and the helmet 4 includes the headband 46 and / or the adapter plate, the adapter plate, or the headband 46 when the helmet 4 does not include an adapter plate, is connected to the second fastening system 100 of the display device 6.

[0070] Furthermore, when the binoculars 7 are not needed but the helmet 4 is necessary or simply desired by the operator, it may be possible to remove the binoculars 7 from the helmet 4, as shown in [Fig. 9], and simply attach the display device 6 to the helmet 4. However, during the day, for example, it may be necessary to protect the operator's eye 8 from external brightness or any other visual nuisance, such as dust and particles. Thus, according to a variant shown in [Fig. 9], a movable visor 9 may be used to protect the operator's eye.

[0071] Therefore, the viewing system 2 includes the movable visor 9, which can be, by way of indicative example, a solar visor.

[0072] When the cranial support 4 is a helmet, as shown in [Fig.9], and in order to associate the movable visor 9 against the display device 6, the movable visor 9 includes a plate 92 allowing a fixing against the binocular support fixing interface 61 in a manner similar to the fixing of the binoculars 7 so as to ensure mechanical retention of the movable visor 9 against the display device 6.

[0073] The movable visor 9 may also include a visor pivot 94 allowing the movable visor 9 to be rotated parallel to the transverse axis A3 so as to remove the movable visor 9 from the operator's field of vision. This rotation also has the advantage of allowing the display device 6 to be rotated about the second axis A2.

[0074] Furthermore, when the cranial support 4 is a headband or a headband, the plate 92 is not suitable for attaching the movable visor 9 to the headband 4. Therefore, the display device 6 includes a first pole of magnets 600 and the movable visor 9 includes a second pole of magnets 900 complementary to the first pole of magnets 600. The first pole of magnets 600 and the second pole of magnets 900 are magnetically connected so as to keep the movable visor 9 in contact with the display device 6. The first pole of magnets 600 and the second pole of magnets 900 are sufficient for attaching the movable visor 9 to a headband or a headband.

[0075] When the cranial support 4 is a helmet, the distance between the first pole of magnets 600 and the second pole of magnets 900 increases, which impairs the magnetic retention of the movable visor 9 and necessitates attachment via the plate 92.

[0076] The movable visor comprising, on the one hand, the second magnet pole 900 and, on the other hand, the plate 92, thus has the advantage of being suitable for attachment to any which cranial support 4 mentioned previously.

[0077] The invention is also aimed at operators such as emergency medical services (SAMU) or offshore operators who need a visual sight for routine missions and who sometimes require night-vision goggles. Since the device can be mounted on a headband or helmet, it allows for the acquisition of a single system. The visualization system is then said to be attached to the aircraft or helicopter, and the headband and helmet belong to the pilot. The pilot chooses their "head support" before the flight, depending on the mission.

[0078] This second advantage of the invention particularly justifies the common visor shown in [Fig.9]. The pilot has a visor and a viewing device that he can use with a headband or helmet with or without night vision goggles.

[0079] Thus, the invention presents a detachable display device 6 allowing the display device 6, binoculars 7, or a movable visor 9 to be combined with a plurality of head supports such as a protective helmet, a headband, or a rigid headband. The entire display system thus has the advantage of being interchangeable and adaptable to any in-flight surveillance situation and of reducing operator fatigue associated with the use of different systems, sometimes involving bulky systems.
