Initially, these conditions are generally mild and localized, but if they are left untreated, or if they occur in relatively older people, these conditions can become a real impairment during and after sleep.

By way of example, the mentioned condition may consist of neck pain such as torticollis, or an actual contusion of the shoulder muscles or cartilage of the shoulder, or even sleep apnea, snoring, or lumbar disorders.

From the state of the art, a variety of accessories are known for addressing and curing these problems. In particular, a large number of pillows of various shapes, constructions and materials are known, some even being referred to as "ergonomic" or "shape memory" pillows. As an example, what is mentioned can be constituted especially by the pillows described in documents WO-0238013A1, FR 2825602 or even EP 0373520.

Unfortunately, those different pillows are ineffective for relieving joint pain, especially in the cervical spine and shoulders, since they are not adapted to adequately or properly match all the conditions that the person using them takes during sleep. posture (especially in the two main sleeping positions consisting of supine and side lying, and sometimes curled up in the "fetal" position). In particular, existing pillows do not properly support the head in the side sleeping position because they are often not high enough, causing the cervical spine to be misaligned or angled relative to the rest of the spine. As a result, sleeping persons often move one arm under the pillow to raise it to the proper height, often resulting in uncomfortable postures and shoulder pain due to deformation and twisting of these joints during sleep.

Contents of the invention

The accessory 1 constitutes a three-body cushion comprising: a central first cushion 3, on a stable base 2, said central first cushion 3 being rested on the central part ₂₁ of the base 2; and Two side pads 4, 5, located symmetrically on either side thereof, are each raised relative to the central pad 3 by means of a respective engaging arm 6, 7, which is lifted via its bottom end. Fixed to or integrally formed with each end ₂₂ of the stabilizing base _of the accessory 1 and secured via its top end to each side for supporting one of said side cushions 4,5. The panels 8, 9 are or integrally formed with each panel 8, 9 and the side cushions 4, 5 are tied to the respective panel 8, 9 by any suitable means.

The base 2, the engaging arms 6, 7 and the support plates 8, 9 of the side cushions are preferably made of such a material that the head of a sleeping person resting on one of the cushions 3, 4, 5 of the accessory 1 Under repeated application of force, the material exhibits sufficient stiffness without bending, twisting or even cracking. As an example, the base 2, the engaging arms 6, 7 and the support plates 8, 9 of the fitting 1 may be made of a metallic material such as iron, or preferably aluminium, or even, in a preferred manner, such as polypropylene, high density polyethylene or even Made of thermoplastic materials such as acrylonitrile butadiene styrene (ABS).

The central pad 3 and the left and right side pads 4 and 5 preferably have a relatively small thickness e compared to existing pads and pillows known in the state of the art. Advantageously, this thickness e has a range from 5 cm to a maximum of 10 cm, the constituent material of the upholstery being preferably a synthetic material foam, in particular whose density and flexibility properties are variable and chosen as the preference of the individual using the accessory. Favorite function. However, the foam used and its thickness should be chosen such that when a person rests his or her head on one of the cushions 3, 4, 5 of the accessory 1, it is sufficient to prevent the person from perceiving the Any contact with the base 2 or with the side plates 8,9.

As shown in FIGS. 1 and 2 , the base 2 and the plates 8 , 9 for supporting the side cushions 4 , 5 are substantially planar and rectangular, and have a thickness smaller than the cushions 3 , 4 , 5 of the accessory 1 . Although not essential, such a planar rectangle of the base 2 is particularly advantageous for obtaining good stability of the fitting 1 when in use, which mostly takes place when exhibiting flexibility (the flexibility of which is defined by the and be quantified) on the mattress. Therefore, in order to exhibit a suitable stability on all types of mattresses, in the preferred embodiment shown in the figures, the base 2 of the accessory 1 of the invention preferably has a length L and a width l, the length L being at the base The width l is measured in a direction perpendicular to the length L of the _base , and is preferably at In the range of 140mm to 220mm.

This length L of the base 2 makes it possible to obtain an accessory with optimum stability when used to support the head of a recumbent person, and also to allow the accessory to be easily placed and adapted to fit any type of "standard" single A person or twin mattress, the width of this "standard" mattress is usually in the range of 70cm to 200cm.

Furthermore, it should be noted that in the present invention the width 1 of the base 2 does not have to remain constant everywhere along the base. In particular, between the central part ₂₁ of the base 2 (on which the central cushion 3 rests) and the bottom ₂₂ (which supports the left and right side cushions 4 and 5 via the joint arms 6, 7 and via the flat plates 8, 9) , the width l can vary. However, _for each of the parts ₂₁ and ₂₂ of the base 2, _this width l It is still preferred to follow the range defined above from 140 cm to 200 cm.

According to a first essential feature of the fitting according to the invention, the engaging arms 6, 7 support the plates 8, 9 at a distance above the base 2, so that the two left and right side cushions 4, 5 are arranged higher than the fitting in such a way 1, the central cushion 3, that is: when a person is lying on his side, for example, as shown by the dotted line (ghost line) in Figure 3 and the continuous line (uninterrupted line) in Figure 9, the higher position of the side cushion will compensate the shoulder The height of the head, thereby supporting the head T so that it is at a height sufficient to keep the cervical spine of the spine of the person 1 aligned with the rest of the spine. Thus, with respect to the base 2 of the accessory 1, the engaging arms 6, 7 support the first plate 8 on which the right cushion 4 rests at a distance E, and the second plate supporting the left cushion 5 at a distance E' 9. The spacing values E and E' are preferably in the range from 5 cm to 25 cm, and more preferably in the range from 5 cm to 15 cm.

In a particularly advantageous manner, according to a preferred characteristic of the invention, the engaging arms 6, 7 have adjustment means for adjusting the height E of the plate 8 supporting the right upholstery and the plate 9 supporting the left upholstery , E′, so that the two side cushions 4, 5 dedicated to supporting the head T of a person lying on one side can move vertically, for example according to the double arrow F1 in FIG. 3 .

Especially as shown in Figures 3, 10, and 11, the adjustment device can adjust the distance E, E', so that when the user I in the side lying position presses the side cushions 4, 5 of the accessory 1 with the head T When cushioned on the left or right side, the user's head T is properly aligned with the axis Dc of his or her spine without any misalignment of the person's neck that could cause neck pain.

This adjusting device is suitable for properly adjusting the spacing E, E' to leave a space between the base 2 and each of the side cushions 4, 5, as shown in FIG. This leaves room for it to move under the side cushions 4, 5 (on which the person rests his or her head).

Furthermore, according to another essential feature of the invention, as shown in Figure 4, the plates 8, 9 for supporting the left and right side pads 4, 5 of the accessory 1 are suitably mounted on their respective joint arms 6, 7, for enabling them to pivot about the respective longitudinal axes of said arms (shown by the double arrows F2 and F3 in FIG. Position the cushion 3 at an angle in the center. Angular positioning of the side pads should be allowed in such a way as to pivot angular sections of 0° and ±45° relative to the normal position of the side pads. This helps to enable the individual user to choose the best position for the user's head supported by the side cushions 4, 5 when the user is lying on their side, regardless of the relative position of the rest of the user's body with respect to the accessory, Especially regardless of the twisting situation of the user's body (for example when the person 1 is in the "fetal" position). Thus, the fact that the side cushions can be positioned at an angle when he or she is sleeping, even in the "fetal" position, allows the person to have enough area to support their head and to maintain a comfortable position .

In a preferred embodiment, adjustment means for adjusting the spacing E, E' formed by the joint arms 6, 7 between the base 2 and the support plates 8, 9 of the side cushions 4, 5 are advantageously incorporated into the joint. and at the same time angularly adjust the side pads 4,5 so that they can rotate relative to the longitudinal axis of the engaging arms 6,7.

For this purpose, the adjusting means advantageously consist of screw means, for example consisting of a nut and bolt system comprising, for example: tapped tubular sleeves 10, 11, fixed to the base One of the ends 2 ₂ of 2 is integrally formed with one of the ends 2 ₂ and cooperates with the screws 12, 13 fixed via one end thereof to the side cushions 4, 5. One of the plates 8,9 is or integrally formed with one of the plates 8,9. In this configuration, the screws 12, 13 can then be screwed into and out of the internally threaded sleeves 10, 11 by turning the plates 8, 9 and their respective supporting cushions clockwise and counterclockwise , to adjust the spacing E, E' between the base 2 and the flat plates 8, 9, and at the same time adjust the angular positioning of the flat plates and even the angular positioning of the cushions supported by them, so as to obtain support for the head T, which is suitable as Function when person 1 (who is the user of accessory 1 ) is in the prone position.

It should be noted that in the above described embodiments the adjustment means for adjusting the distances E, E' consist of screw means 10, 11, 12, 13 fixed to the base 2 or to the plates 8, 9, fixed to the end 2 of the base 2 ₂ or the internally threaded sleeves 10, 11 integrally formed with the end ₂₂ of the base 2 and the screw rods 12, 13 fixed to the plates 8, 9 or integrally formed with the plates 8, 9 are all known by those of ordinary skill in the art.

In addition, other means of adjusting the spacing E, E' between the base and the plates 8, 9 may be considered, as well as for pivoting the plates and side cushions about the longitudinal axes of the joint arms between the base 2 and the plates 8, 9 turn other devices. As an example, as means for adjusting the length of the engaging arms 6, 7 and thus the spacing E, E′, in particular it is possible to use single- or double-acting members or electromechanical actuators associated with suitable control means. actuators, even using arms made of short telescopic rods, the length of which can be set by means of cotter pins or pins, for example inserted into the In the orifices in the parts of the telescoping rod.

In the same way, as means for pivoting the side cushions 4, 5 and their plates about the axes of the respective joint arms 6, 7, it is also conceivable to use means for rotationally fitting the plates to their joint arms. Any type of means, even means for rotationally fitting the joint arm to the base 2, in particular a pivot optionally associated with means for rotational guidance such as optionally lubricated rollers or other bearings Install the device.

In order to obtain greater mobility of the side pads 4,5 relative to the base 2 and the central pad 3, it is also possible to provide for mounting the plates 8,9 supporting the side pads 4,5 on their joint arms 6, Other variants on the 7.

In a first variant, in particular, it is possible to provide split joint hinges and even, if this variant has several branches, link joint hinges between the top ends of the joint arms 6,7 and the plates 8,9. The hinges are shown in Figure 5 and Figure 6 respectively.

As shown in FIG. 7, as a modification of the above configuration or in addition to the above configuration, it can be provided that the flat panel is mounted in the manner of straight slide rails or round slide rails (these slide rails are formed in the end portion ₂₂ of the base 2). 8, 9 are the bases of the engaging arms 6, 7 so that the engaging arms can be properly positioned as a function of comfort for the user of the accessory 1 of the invention.

According to another preferred feature of the invention, it is also possible to provide the central and left and right side cushions 4, 5, wherein said central cushion is to be mounted removably on the central part 21 of the base 2 of the accessory 1 of the invention , and the left and right side cushions 4,5 will be movably installed on the flat panels 8,9. This facilitates the replacement of each of the pads 3 , 4 , 5 , based on their state of wear, or even on the basis of their diminishing function of their flexible properties, depending on the requirements of the person using the accessory of the invention. For example, it is possible to provide different sets of cushions (which are marketed with different characteristics), or to provide sets of cushions sold independently of the accessories of the present invention, each user choosing a particular type of cushion as he or she considers Her own comfort and more preferred function.

Although not shown in the drawings, it is also possible and advantageous to provide a center in the center portion ₂₁ of the base for supporting the central cushion 3 and in the middle of the plates 8,9 for supporting the side cushions 4,5. Concavity, so that soft pads 3,4,5 can partially sink into the center portion ₂₁ of the base and in the flat plates 8,9, thereby further improving the comfort characteristics of the accessory 1 of the present invention to obtain support for the head of the individual user The mobility of the head is improved regardless of his prone position, or the position of his or her head resting on the cushion of the accessory of the invention.

More specifically, Figures 8 and 9 illustrate in detail how to use the accessory 1 of the invention for supporting the head. FIG. 8 shows a person 1 in a sleeping position lying on his back. In this pose, the person's head T should be supported and held flat, and substantially aligned with the person's back, to avoid excessive stress on the cervical vertebrae in the neck. This is also the reason why in this position the person's head T is then placed on the central cushion 3 of the accessory 1 of the invention, which is of such a small thickness that once the head rests on the central cushion 3 , the person 1 is not subjected to stresses on the head from the cushion 3 which tend to cause the head to twist towards the chest, but instead keep the head level with the rest of the spine in the normal curve of the cervical spine , so that neck pain, sleep apnea and/or snoring can be avoided for persons lying on their back in this way.

Conversely, if the person prefers to sleep on their side, as shown in FIG. Upholstery, while the plates 8, 9 have distances E, E' relative to the base of the accessory 1 of the present invention. As the morphological function of people 1, people can use adjusting device to adjust the spacing E, E ' between side cushions 4,5 and the base before falling asleep, so that people's posture is as comfortable as possible to fall asleep, spacing E, E' generally corresponds to the width of a person from shoulders to head. As shown in FIG. 4, by pivoting the cushion about the longitudinal axis of the engagement axes 6, 7 of the flat plates used to support the side cushion, the person 1 can also adjust the angular positioning of the side cushions 4, 5 to be able to position him or Her head is positioned precisely in line with the rest of his or her spine while lying on her side, or optionally curled up in a "fetal" position. Furthermore, the space created by the spacing E, E' between the base 2 of the accessory of the invention and the side cushions 4, 5 also enables the person to move his or her arm B to the side cushions (he or she moves them The head rests on the side cushion) below (under the cushion 4 of FIG. Minimizes potential pain in his or her shoulder.

It should be noted that during the same sleep phase, the person 1 can switch from a supine position with the head T resting on the central cushion 3 of the accessory 1 to a side sleeper with the head resting on one of the side cushions 4, 5 without any difficulty. posture. Even if there is no continuity of material between the central pad 3 and the side pads 4, 5, when the person 1 turns from a supine position through the leverage effect of the shoulders (the shoulders that the person compresses to change from one posture to another) Moving from one position to the other is very natural when moving to and from the side-lying position to the supine position. In the case of the head, due to the relative stiffness of the parts of the accessory 1 that form the bearing surface for the head against which the head can roll from a supine to a side position and vice versa, this Postural changes are easier than with traditional pillows, however often times the head tends to sink into and stay in the pillow while the body simply goes from one position to another.

Thus, the accessory 1 of the invention enables the user to obtain head support during sleep, which is functional and ergonomic, regardless of the sleeping position, while still maintaining the head relative to the user's spine. The other parts of the body are properly held and any forces exerted by the head and body on the shoulders and arms are relieved in the side lying position, thereby significantly reducing pain caused by uncomfortable sleeping positions on the cervical spine and shoulders, among others. pain and injury.
