    专利说明:

    [0001] The invention relates to a headrest device which makes it possible to keep the user's head tilted backwards for a long period of time and / or frequently. In situations where an individual has to hold his head tilted back for a long time, for several hours sometimes or frequently to look upward, pains or even lesions, appear in the neck and vertebrae of this individual, because compression created on the back of cervical vertebrae.
    [0002] Such situations can be encountered for example in the field of climbing for the assurance of a climber performed by a person who must keep permanent visual contact from the ground on the climber to ensure maximum safety in case of a fall . The person who assures the climber, until now, has the obligation to hold the head tilted back to keep the eye contact, which, after a while, causes pain in the cervical vertebrae by the compression of these vertebrae, and muscular tension in the neck. It is inevitably that she will relax the surveillance she exerts on the climber while this monitoring must be continuous for the safety of the climber. It has been proposed recently, to avoid tilting one's head back during such insurance, to make available to the insurer, prism glasses that can return the vertical image while we look at the horizontal. However, these glasses do not allow direct eye contact and can cause a feeling of vertigo. Such situations can also be encountered, for example, for individuals working in the building, especially when applying plaster or ceiling paints. The invention aims to solve these problems by providing a headrest device that allows an individual to have the head extended backwards, for a prolonged and / or repeated, without feeling tiring pain.
    [0003] The invention further aims to provide a headrest device allowing the user to remain upright and mobile the time necessary without being bothered by this device, and without feeling pain or fatigue.
    [0004] The invention thus provides a headrest device comprising a headrest on which the head of a user of the device comes to rest when it is extended rearward, this headrest being mounted on a back support by via elastic connecting means. Said device further comprises means for holding the back support for positioning and supporting the back support in the upper back of the user, in a position such that the head of the user comes to rest on the headrest when it is tilted backwards, while the elastic connection means exert a restoring force tending to cancel the weight of the head tilting backwards. Preferably, according to the invention, the headrest device further comprises a bearing structure which attaches around the body of the user of the device, and on which is fixed the back support of said device.
    [0005] Preferably according to the invention, the carrying structure comprises a pair of shoulder straps adapted to take place on the shoulders of the user to which are fixed, preferably reversibly, said holding means of the back support. According to a particular case of the invention, the means for holding the back support are in the form of a strap going from one strap to the other of the supporting structure. According to another particular case of the invention, the means for holding the back support are in the form of two straps disposed on either side of said support, each of the straps being fixed at one of its ends to the support. dorsal, the other end being fixed on the supporting structure, in particular on the strap corresponding to the strap that is to say located on the same side as the strap.
    [0006] According to a preferred embodiment of the invention, the support structure of the device is a harness formed of belts and a pair of straps in which the user comes to pass arms, each opposite ends of the strap coming from fix 5 on the front part of the corresponding strap. Preferably each of the straps is equipped with a fastener to which is fixed the corresponding end of the retaining strap. The strap is advantageously provided at each of its ends with a clip which is clipped on the corresponding fastener equipping the strap so that one can easily attach and detach the strap. According to a particular case of implementation of the invention, the back support is in the form of a plate provided in its upper part with lights through which the holding strap passes. The strap may also be provided at each of its ends with a coupling which is coupled, for example by force engagement, with another fastener present on the supporting structure. In general, however, it will be preferred to pass the strap in a clamping loop, itself attached to the top of the strap. Advantageously, according to the invention, the elastic connection means which connect the headrest and the back support, fit together in a disassemblable manner, preferably by force engagement, on the one hand in the headrest and on the other hand part in the back support, 25 if necessary via a holster inserted into said back support. The headrest portion and the elastic connection means can thus easily be removed from the device by the user himself, when he does not need it, and yet the user can keep the carrier structure and the back support 30 in place on him. Among the different types of springs that can constitute these means of elastic connection between the headrest and the back support, it will be preferable to use, according to the invention, a leaf spring disposed between the headrest and the back support in parallel with the axis of the spine.
    [0007] The elastic connection means between the headrest and the back support of the device, which are preferably in the form of a leaf spring, tend to cancel the weight of the head when the user of the device inclines the head towards the rear. They offer progressive resistance as the head is inclined more and more to the rear. As a result, the user no longer feels muscle tension in the neck or pain in the cervical vertebrae. In addition, the person using the headrest device can remain upright and mobile, or even sit or lie down. And in general, the regular wearing of the device according to the invention is beneficial in terms of health. Also preferably according to the invention, the blade has a double curvature having two curvatures of opposite directions, the upper curvature being directed towards the inside of said device, ie towards the head in support, and the curvature The lower part is thus directed towards the outside, which makes it possible to follow as closely as possible the curvature movement of the cervical vertebrae of the user when the head tilts towards the rear. Preferably, according to the invention, the back support comprises a sheath on its outer face, a sheath in which the lower end of the leaf spring engages. Preferably this blade end is engaged, preferably by force engagement, in a case in which has been inserted directly the blade end, shaped truncated cone, which facilitates the insertion of the assembly in the receiver sleeve located on the back plate. Thus, the user can easily set up the headrest on the back support, even by proceeding to the blind. Advantageously according to the invention, several interchangeable leaf springs with different elastic return forces are provided in order to be able to choose among them the most appropriate blade for the morphology of a user, in particular the weight of the head to be supported. . These blades may be of plastic or metal for example, in practice any material to obtain the properties of strength and stiffness adapted to their function in the device of the invention.
    [0008] Preferably according to the invention, the headrest is made of a rigid piece covered with a padding ensuring comfort for the user, such as a removable thick envelope forming a head cushion. Preferably the rigid piece supporting the head has a shape to surround the back of the user's head of the device and thus ensure a good hold of the head. Thus it is advantageously provided according to the invention that said rigid part comprises two raised lateral lugs, each towards the inside of the device, that is to say in the direction of the head in support, as well as an upper lug. Advantageously, the device according to the invention has means for adjusting its dimensional characteristics, both in height and depth at the back of the neck, which make it possible to adjust it to the morphology of the user and / or to his comfort. According to a preferred case of the invention, these adjustment means are in the form of junction elements of the male-female type. One is for example present on the elastic connection means and the other complementary elements are present on the headrest and / or in the case inserted in the back support 20. For example, lugs or pads are present on the elastic connection means, in particular at one of its ends, and cooperate with complementary lights present in the headrest and / or the case inserted into the back support. In particular, these adjustment means are present at the upper end of said elastic connection means, and cooperate with complementary means present on the headrest. For example, lugs at the upper end of a leaf spring are inserted into the lights made in the headrest. These adjustment means may also advantageously serve as means for forcibly fitting the elastic connection means in the headrest. Optionally and in particular, the leaf spring has studs or lugs at its lower end which fit into the slots in its case so that the headrest can be adjusted in height.
    [0009] The various adjustment means can be used also to adjust the head cushion of the headrest and thus improve the comfort of the user. According to a particular case of implementation of the invention, the supporting structure of the headrest device is a harness formed of belts and a pair of shoulder straps materialized by the strap for holding the back support completed by a front portion, on either side of the harness, in continuity with rear lateral straps fixed on a back piece placed at the level of the 10 lumbar vertebrae and / or dorsal vertebrae of the user. Preferably such straps connect to each other reversibly at the sternum of the user through transverse anterior straps provided with fasteners. Such a configuration ensures a good hold of the harness on the body of the user, and it also participates in retaining the back support of the headrest against the upper back of the user. According to a particular embodiment of the invention, clamping loops are attached directly to the shoulder straps of the carrying harness to allow the user to easily adjust the length thereof by acting on each individually by front. According to another advantageous embodiment, not shown, the means for holding the back support are in the form of two straps, each being fixed, for example sewn, at one of its ends to the back support, at the other end. the strap being fixed on the corresponding shoulder strap of the carrier harness, that is to say on the same side as the strap. In this embodiment, the holding strap does not bear on the neck of the user. Alternatively according to the invention, the carrying structure may be in the form of a backpack having a pair of carrying straps each equipped with means for fixing the means for holding the back support of said headrest device. The headrest device according to the invention can be used in particular in the field of climbing by the one who provides a climber or in the field of the building by the one who must perform ceiling work for example painting, repair, by window cleaners or in any other application where a person must keep the head tilted backwards continuously or repeatedly. The invention will now be more completely described in the context of preferred features and their advantages, with reference to FIGS. 1 to 3 in which: FIG. 1 is a side view schematically showing the headrest device according to the invention; , worn by a user; FIG. 2 represents the headrest device according to the invention, viewed as a whole from the front of said device; - Figure 3 is an exploded perspective view of the headrest device according to the invention, seen from the rear of the device, without its supporting structure. Figure 1 shows schematically the headrest device according to the invention seen from the side and shown carried by an individual who is the user of the device. FIG. 2 represents an example of a headrest device according to the invention provided with its carrying structure 5 which is worn on the user as shown in FIG. 1. As shown in FIG. 1, the headrest device comprises a headrest part 1 on which the back of the head of a user bears in particular when the head is tilted backwards. The headrest 1 is movable back and forth to follow the path of the head while supporting it with a resiliently connecting element between said headrest 1 and the back support 3 of said device. This connecting element is here in the form of a leaf spring 2 which is inserted vertically between the headrest and the back support. The leaf spring 2 provides progressive resistance as the head is tilted further and further back, and tends to cancel the weight of the head resting on the headrest.
    [0010] The back support 3 is also maintained by a strap 4 which attaches to a harness 5 constituting the carrying structure of the assembly, and according to the example described here, more precisely on the shoulder straps B1, B2 of the harness 5, thanks to to clip fasteners 41 and 42 present at the end of anterior straps S1 and S2 installed on the front portion padded portions of the shoulder straps that are applied to the shoulders of the user. In another embodiment, these fasteners are replaced by clamping loops that are attached directly to the shoulder straps of the carrying harness. S10 and S20 transverse belts, respectively connected to said anterior belts S1 and S2, are provided with fasteners that can be clipped to each other so as to be attached to the torso of the user. According to the example of Figure 2, the harness 5 further comprises a belt whose centerpiece D is placed at the lumbar vertebrae of the user. The dorsal piece is completed on both sides, at each of its lateral ends by S5 and S6 belts fastening reversibly to one another in closing the belt. However, in a simpler version, the back piece D plays the role of back cushion without closing in a belt. It is on him that the straps of the harness are fixed. Indeed, the back piece D has a side belt S3 and S4 on each side, one end of each side belt being fixed to it and the other end attaching respectively to the belt S1 at the front end of the strap B1 and on the belt S2 at the front end of the strap B2 for the good maintenance of the harness on the body of the user. The back strap C shown in the figure is optional. At the simplest, one prefers to dispense with it, in which 30 cases the shoulder straps of the harness are then materialized by the strap 4 completed by the front part of the shoulder straps in continuity with the side belts S3 and S4. Figure 3 shows an exploded headrest device seen back, without the carrier structure, to more precisely show its mounting according to the example described.
    [0011] The headrest 1 is formed of a rigid piece 10 which comprises, according to this example, three tabs, two left and right lateral tabs 12 which are slightly curved to surround and hold the head of the individual who uses it, as well as an upper leg 13 not raised. This rigid piece 10 is inserted into a padded cover 15 to provide comfort to the user. The rigid part 10 comprises a housing 14 in which is inserted the upper end of the leaf spring 2. According to the example described, the leaf spring 2 is equipped with adjustment means to adjust the height of the rest head 1 for the comfort of the user. The leaf spring comprises adjustment pins 23 which will fit in the slots 140 made in said housing 14. The padded cover 15 advantageously covers the whole. The spring blade has at its other opposite end, or its lower end, adjustment lugs 24 which are inserted into slots 250 made in a rigid case 25. The case 25 is then inserted into the back support 3. Its presence facilitates the withdrawal and setting up by the user of one hand and the blind. The coupling between the headrest and its support is functional without requiring any locking. The leaf spring 2 can thus be adjusted at its upper end in the headrest portion and / or at its lower end held in the rigid case 25 inserted in the back support, which allows positioning the headrest under the head of the user, and also to adapt the positioning of the leaf spring and the headrest, depending on the morphology of the user and the comfort sought. The back support 3 is formed of a back plate 31 which is placed on the back of the user, covered with padding, preferably coming into contact with the skin of the user, the case 25 at the end of the blade spring 2 being more precisely introduced into a sleeve 30 present on the outer face of the back support 3. The rear plate 31 further comprises in its upper part, through openings 311 and 312, which are arranged according to this example symmetrically by relative to the median central plane of the support, through which will pass the strap 4 which allows to fix the elements of the headrest on its supporting structure, here formed by the harness 5. As can be seen in particular in the schematic figure 1, the leaf spring 2 comprises a double curvature formed of a first curvature 20 and a second curvature 21 in opposite directions. The first curvature 20 in the upper part of the blade, directed towards the inside of the device, that is to say towards the body 10 of the user, makes it possible to match the curvature at the cervical level of the user, when this user tilts the head backwards, while the second curvature 21, facing the outside of the device, also allows to press or bring the curvature closer to the cervical. The upper curvature 20 also provides the elasticity necessary for the device to retain the weight of the user's head when his head is extended backwards and thus allow the vertebrae to not collapse. on the other, that the neck muscles remain relaxed and thus not cause pain and provide less fatigue when the user has to hold the head back or frequently has to extend the head backwards. According to this device, the strap 4 which makes it possible to hold the back support of the headrest at the top of the user's dorsal vertebrae, returns the force applied by the head on the back support 3 to the dorsal vertebrae, passing over it shoulders. An advantage of the headrest device according to the invention is that it is removable and therefore there is no need to remove the carrier harness when not in use. It is possible to remove only the headrest and the spring blade, these elements possibly being for example fixed to the supporting structure by means of a ring system, of carabiner type. The back support 3 can remain in place on the harness. The user can thus keep the device within reach when he does not need to look up for a while, while loosening the carrier system by loosening the straps S3 and S4 to be more comfortable. comfortable.
    [0012] It will be emphasized here that, although this has not been shown in FIG. 2, the free end of the anterior belts S1 and S2 includes a ring making it easier to grip this part of the straps to pull on them and thereby release the tightening loops. . Nevertheless, it follows from the foregoing that the invention is not limited to the embodiments that have been specifically described and shown in the figures. For example the carrier structure may be an existing backpack, with shoulder straps as is conventionally the case, instead of being a belt harness as described, means of fasteners to be provided on the straps of the backpack to fix the means for holding the back support, particularly when the latter are a holding strap.
