Description

Title of the invention: Support device for the positional adaptation of at least one segment of a user's limb. Technical field

[0001] The present invention falls within the field of ergonomic pillows or cushions.

[0002] More particularly, the invention relates to the field of modular equipment, such as cushions or pillows, intended to promote the comfort of a user regardless of the body position adopted and to relieve joint and muscle tension resulting from professional activities or activities of daily life.

[0003] The invention relates to a support device for the positional adaptation of at least one segment of a limb of said user. In particular, it allows control of the mechanical positional angles responsible for pain in the affected limb segment or limb.

[0004] From a biological point of view, a limb is understood to mean each of the four mobile and articulated appendages, linked to the trunk and arranged in symmetrical pairs, and whose main function is either grasping in the case of the arms, or locomotion in the case of the legs.

[0005] Also, the term upper limb means each of the two articulated appendages attached to the upper part of the user's trunk by means of the shoulder girdle. The upper limb is made up of four segments: the shoulder, the arm, the forearm, and the hand.

[0006] Finally, the term lower limb refers to each of the two articulated appendages attached to the lower part of the user's trunk via the pelvic girdle. The lower limb comprises four segments: hip, thigh, leg, and foot.

[0007] The present invention has applications in many fields such as improving the well-being of individuals, relaxation, post-operative recovery or recovery after sport.

[0008] [State of the art]

[0009] Nowadays, musculoskeletal disorders and limb injuries related in particular to accidents, professional activities, advancing age, or the practice of sport are increasingly frequent.

[0010] As an example, shoulder pain affects 7 to 35% of adults, and has several major identified causes including: adhesive capsulitis, osteoarthritis, fractures or rotator cuff injury.

[0011] This results in significant pain for the individual, leading to a major sleep disturbance that considerably impacts their abilities during waking hours, causing difficulties in recovery or concentration. This disturbance is also likely to lead to mood disorders, potentially progressing to anxiety and depression.

[0012] In order to improve the positional comfort and sleep of a user, many devices are known, such as cervical pillows, nursing pillows, or even pre-shaped pillows dedicated to the lying position.

[0013] However, in the context of existing pain in a limb, a user wishing to implement these solutions must either repurpose them or accept a predefined posture that is not easily adaptable to their body shape. Thus, cervical pillows are initially designed to address pain located in the user's neck and aim to improve the positioning and alignment of the cervical spine, not of a limb segment or the individual's limb. For their part, nursing pillows have a more adaptable structure but are usually of a uniform volume and quite bulky. Finally, pre-shaped pillows, conforming to a specific area of ​​the body or a limb, are most often intended for use while lying down. Their standardized shape does not allow for adjustable use at any time, nor for optimal use during the day. Summary of the invention

[0014] The invention aims to improve the situation described above.

[0015] The invention aims to remedy the disadvantages of the prior art, by proposing a device adaptable to the different morphologies and ages of users, regardless of the time or posture adopted.

[0016] The comfort of limb positioning provided by the device is therefore of great interest for improving these situations, with an objective of relaxation and release, promoting a faster and qualitative recovery.

[0017] Furthermore, the proposed support device is universal in that it allows adjustment to the natural anatomical angles of the user's upper limbs. In addition, it can be used regardless of the body position adopted: lying down, sitting, or otherwise, and guarantees adaptation to the anatomy and morphology of its user.

[0018] Also, if the origin of the pain is located in the neck region, the device contributes to an even more significant reduction of joint and muscle tension compared to isolated cervical care and helps to improve the symptoms radiating towards the shoulder.

[0019] Thus, the object of the present invention relates to a support device for a positional adaptation of at least one segment of a user's limb.

[0020] Advantageously, the support device according to the present invention comprises at least two cushions, each cushion comprising a body and having an upper face, an lower face and a peripheral edge.

[0021] Each cushion thus has faces that can be in contact with the user's body and support the limb segment or limb in question, and is associated with at least one other adjacent cushion by a hinged connecting means.

[0022] Advantageously, the cushions are assembled in pairs by a hinged connecting means, configured to allow passage from a first position called folded to a second position called unfolded.

[0023] In the first so-called folded position, the upper face, respectively lower face, of a first of the cushions of the pair is at least partially superimposed with the upper face, respectively lower face, of a second of the cushions of said pair.

[0024] In the second so-called unfolded position, the faces of the cushions of the pair are not opposite each other.

[0025] Thanks to this arrangement, a device is obtained in which the cushions can be folded into multiple configurations and in multiple locations.

[0026] This allows the user to relieve pain in multiple ways, the location or intensity of which may change, both during daytime and nighttime periods, whether related to inadequate positioning, an illness or trauma of the limb segment or limb.

[0027] These modular cushions thus allow support for the arm, forearm, and hand. Limb segments or limbs can also be supported symmetrically, for example, in the case of the upper limbs.

[0028] The proposed support device can therefore address one or more problems, simultaneously or over the course of the user's life, and is easier to use compared to equipment specifically designed for the painful area, which has little adaptability and often requires complex handling.

[0029] Preferably, the support device comprises three cushions.

[0030] Most preferably, the support device comprises two cushions.

[0031] In other embodiments, the device may also include a cover with as many compartments as there are cushions. Such a cover, for example, facilitates maintenance or allows the device to be personalized, for example, by modifying the user's tactile perception.

[0032] Advantageously, in this embodiment each compartment is provided with an opening leading to a housing space for an associated cushion body.

[0033] When the compartment receives the body, the compartment presents the upper face, the lower face, and the peripheral edge. In other words, each compartment receiving a body itself becomes a cushion presenting said faces and edge.

[0034] Optionally, the opening can be fitted with a closure system, for example with a flap, buttons or a zipper.

[0035] In an embodiment where the cushions are assembled together without a cover, the body of the cushion has the upper face, the lower face and the peripheral edge.

[0036] As previously mentioned, in order to finely adjust the positioning angles of the limb segments, the cushions are assembled in pairs by a hinged connecting means. This allows the user to choose between a folded position of the cushions, in which they are at least partially overlapped, and an unfolded position in which, for example, only one cushion can be used per limb segment.

[0037] The user can thus create a modular thickness that can be positioned laterally and / or supported by him and increase or decrease, according to the need, the moment and the posture taken, the angles of retropulsion, antepulsion and rotation for the upper limb.

[0038] Advantageously, the hinged connecting means has at least one through-hole. This hole can, for example, allow a strap of another device worn by the user, such as a removable shoulder support brace, to be passed through it.

[0039] Of course, all combinations are possible with regard to the number, size and thickness of the cushions as well as the choice between using identical or different cushions.

[0040] More particularly, one or more cushions located under the arm allow adjustment of the angle a between the arm and the user's trunk, which corresponds to the angle of retropulsion or antepulsion of the shoulder joint, while one or more cushions located under the forearm allow adjustment of the angle [3 between the forearm and the trunk, which corresponds to the angle of rotation of the shoulder joint.

[0041] Antepulsion corresponds to the raising of the arm forward, while retropulsion moves the arm backward. In the case of the upper limb, slight retropulsion corresponds to the usual position taken by the arm of a subject lying naturally without using a support device.

[0042] Preferably, the joining means for assembling the cushions comprises a spacer strip extending along at least a portion of the peripheral edge of each of said two cushions assembled in pairs.

[0043] Even more preferably, the spacer strip does not have any padding. Indeed, the spacer strip is not intended to support a section or a member of the user, but allows significant flexibility for the device without creating excess thickness that could impair the adjustment of positional angles.

[0044] In its most common variants, the cushions of the device are substantially rectangular or square, the peripheral edge comprising two lateral edges and two external edges, while the spacing strip extends along at least a portion of the lateral edges.

[0045] However, the cushions can take any shape suitable for the intended application, such as a round shape or having specific edge cutouts.

[0046] Advantageously, each spacing strip between two assembled cushions can have a different width from the other strip(s) provided.

[0047] Preferably, the spacing strip has a width of 20% to 75% of the cumulative thickness of the cushions connected to it, allowing it to play a hinge role without restricting the overlapping of said cushions while maintaining their solidarity.

[0048] Most preferably, a spacing strip has a width between 15 mm and 300 mm.

[0049] Advantageously, in order to obtain on the one hand sufficient volume and / or thickness at the level of the cushions for adjusting the positioning angles of the segments of the limb or limb and on the other hand a weight which does not hinder the user, the body of the cushions is made or filled with a material having a density between 1 and 30 kg / m3.

[0050] In order to ensure both comfort and sufficient support to the limb segment or limb, the body of the cushions is advantageously made or filled with a material having a Young's modulus between 0.01 GPa and 30 GPa.

[0051] A person skilled in the art knows how to choose the most suitable Young's module according to the morphology and in particular the weight of the user in the range described above.

[0052] The use of materials such as: memory foam, mobile particles, fibers, wadding, is conceivable.

[0053] Each cushion can be filled with a material adapted to the limb segment or limb to be supported. Thus, in some variations, the use of cushions with the same Young's modulus will be desirable, while in other variations and depending on the user's needs, the cushions used may have different Young's moduli. The same applies to the materials used.

[0054] Preferably, the body of the cushions is filled with particles that are mobile relative to each other. The use of particles has the advantage of ensuring perfect adaptation to the user morphology since the padding can move inside the cushion and conform as closely as possible to the limb segment or the supported limb.

[0055] Even more preferably, the body of the cushions is filled with mobile particles having a Young's modulus between 0.2 GPa and 30 GPa.

[0056] In order to ensure satisfactory particle mobility, the body of the cushions preferably has a filling of between 50% and 90% by volume, particularly when the body and / or the cover is made of non-elastic material, such as cotton or linen.

[0057] Even more preferably the mobile particles are spherical balls, this allowing a fluid movement of the lining and ensuring an adaptation to the anatomy and morphology as well as a pleasant sensation for the user.

[0058] When the body of the cushions and the cover are made of a material with elasticity, such as cotton-elastane, the cushions have a filling of between 90% and 100% by volume.

[0059] Preferably, the particles are chosen from a group consisting of: expanded polystyrene, ecographite, cork,

[0060] Preferably, the particles have a size, in their largest dimension, of between 0.2 mm and 6 mm.

[0061] In order to provide constant and reliable support, the support device advantageously includes at least one first attachment, called a positioning attachment, fixed to one side of at least one of the cushions, configured to maintain at least one segment of the limb in contact with said side, and thus prevent any unexpected movement that would alter the chosen positional angle, particularly during sleep. This positioning attachment may, for example, include a hook-and-loop fastener area onto which a wristband, itself made of hook-and-loop material and positioned on the user's limb segment, can be removably and adjustablely attached.

[0062] Finally, to ensure stability, the support device includes at least one second attachment, called a safety attachment, fixed to one of the faces of at least one of the cushions and configured to hold said at least one cushion to the user's body. Preferably, said safety attachment is fixed to a face opposite to that receiving the at least one first positioning attachment.

[0063] Said safety attachment may for example include a self-gripping area on which a strap, itself made of self-gripping material and placed on the user's body, can be positioned in a removable and adjustable manner.

[0064] Thus, for example, in order to secure the support device to the user's trunk, it is possible to use a self-gripping strap that wraps around the trunk and attaches reversibly to a self-gripping area provided on one side of at least one cushion of said device. The trunk, device and upper limb assembly are then held securely together.

[0065] Thus, by the multiplicity of possible conformations and dimensions, the proposed support device can allow a user of any age, from children to seniors, to increase well-being and recovery efficiency following any event, such as an accident, an operation or a sporting activity, which has caused discomfort or pain.

[0104] Fig. 19 represents a user equipped with both a splint and a support device according to the invention. Detailed description

[0105] Different embodiments of the support device according to the invention are shown below in figures 1 to 19.

[0106] The support device is illustrated in [Fig. 1] in a first embodiment without a cover, viewed from the front, where a thin cushion 1 and a thicker cushion 2 are joined by the hinged connecting means 3. In the configuration shown, the cushion 1 and the cushion 2 are substantially rectangular or square, such that the cushion 1 has a peripheral edge comprising two lateral edges 11 and

[0107] two outer edges 12, while the cushion 2 has a peripheral edge comprising two lateral edges 21 and two outer edges 22. Finally, the spacer strip 3a extends along the lateral edges 11 and 21 of each of the cushions 1 and 2 so as to assemble them.

[0108] In a second embodiment of the invention, the support device is provided with a cover as shown in the front view in [Fig. 2], in which the compartments 4 are assembled by means of the hinged connecting means 3. This allows, for example, for greater versatility in the materials, textures, or mechanical characteristics of the device, or, as mentioned previously, facilitates maintenance.

[0109] The cover advantageously comprises as many compartments 4 as there are desired cushions 1 and 2. Thus, in the variant shown in Figures 3 and 4, respectively front view and cross-sectional view, the cover has two compartments 4, Each is equipped with a substantially rectangular or square cushion 1 or 2. The compartment 4, having received the body la or 2a of a cushion 1 or 2, therefore has the upper face FS1, FS2, the lower face Fil, FI2, and the respective peripheral edge of said body la or 2a of cushion 1 or 2. Thus, the compartments 4 shown in [Fig. 4] have the lateral edges 11, the outer edges 12, the lateral edges 21, and the outer edges 22 of the respective bodies la or 2a of cushions 1 or 2. Also, in the variant illustrated in [Fig. 3], the connecting means 3 consists of a hinged spacer strip 3a with a through hole 5. This hole can, for example, allow a strap of another device worn by the user, such as a removable shoulder support brace, to be passed through it.

[0110] Fig. 19 illustrates such a combination of equipment, where the user wears a splint 7 in conjunction with a cushion 2 arranged under the arm and connected by a spacer band 3a to a cushion 1 arranged between the trunk and the forearm.

[0111] In both views of figures 3 and 4, the device is in an unfolded position in which the spacer strip 3a of width D is fully extended and in which the upper faces FS1, FS2, and lower faces Fil, FI2 of the cushions 1 and 2 of the pair are not opposite each other.

[0112] Thanks to the connecting means 3 which allows the passage from a folded position to an unfolded position and vice versa, the user can adapt the thickness of the device and its arrangement according to their needs by positioning the limb segment or the limb on the face(s) most suitable for obtaining the desired effect: relaxation, pain relief, optimal elevation of the limb segment...

[0113] Figures 5 to 7 represent the device still in its second embodiment implementing the compartment cover 4, seen in cross-section, in three examples of folded positions where the spacer strip 3a acts as a hinge so that the upper faces FS1, FS2, respectively lower faces Fil, FI2 of the bodies la and 2a of cushions 1 and 2 are fully superimposed for [Fig.5] or partially superimposed for figures 6 and 7.

[0114] Figures 8 to 10 show a user lying on their back, in the anatomical position known as supine. When this user, in accordance with [Fig. 8], is not using the device, it can be observed that the arm naturally presents an angle α between the arm and the trunk corresponding to a retropulsion angle of the shoulder joint, here with a value of α0.

[0115] In order to relieve pain and reduce anterior shoulder tension caused by the retropulsion of the right upper limb, the user may, for example, choose to use the support device in one of its coverless variants and adjust the antepulsion angle to provide the greatest comfort. For this purpose, as illustrated in [Fig. 9], by using the thickest cushion 1 With the thinner cushion 2 under the arm and the thicker cushion 2 under the forearm, the patient can choose to cancel the angle α between the arm and the trunk. This neutral position is represented by an angle value α1. If this alternative proves insufficiently satisfactory, as illustrated in [Fig. 10], by using the thicker cushion 2 under the arm and the thinner cushion 1 under the forearm, a greater antepulsion angle of the shoulder joint could be obtained, here with a value α2 greater than α1.

[0116] The support device also allows several positioning angles to be adjusted simultaneously.

[0117] Indeed, if the situation presented in [Fig. 10] allows obtaining the largest angle a, the same arrangement of cushions 1 and 2 simultaneously allows the user, as presented in [Fig. 12], by using the thickest cushion 2 under the arm and the thinnest cushion 1 under the forearm, to obtain a small angle of rotation of the shoulder joint, here of value [31.

[0118] Similarly, if the situation presented in [Fig.9] allows obtaining an angle a of zero, this same arrangement of cushions 1 and 2 simultaneously allows the user, as presented in [Fig.13], by using the cushion 1 of the thinnest thickness under the arm and the cushion 2 of the greatest thickness under the forearm, to obtain a greater angle of rotation of the shoulder joint, here of value [32 greater than [31.

[0119] Of course, all cushion configurations are possible in order to optimize user comfort. Thus, [Fig. 14] represents the user in a configuration similar to that of Figures 10 and 12, where the support device now has three cushions: two identical cushions 2 of greater thickness under the arms, and a thinner cushion 1 under both forearms. A symmetrical problem at the level of the limb segments or upper limbs can therefore be addressed by the device.

[0120] Of course, by using a number of cushions and varying thicknesses, it is also possible to address asymmetrical problems.

[0121] In order to avoid any unexpected movement which would alter the chosen positional angle, particularly during sleep, the cushions 1 and / or 2 can be provided, as illustrated in [Fig. 17], with one or more position attachments 6, here in the form of gripping areas that can be attached to bracelets, the two cushions being assembled by the connecting means 3a.

[0122] The device according to the invention is also versatile in its positions of use since a user in a seated position as shown in [Fig. 1 1] can, for example, come and rest several segments of their upper limb on the thickest cushion 2, here arranged under the arm and forearm, while that the hand rests on the cushion 1 of the thinnest thickness, the two cushions being joined by the connecting means 3a.

[0123] In the case of the semi-seated position illustrated in [Fig.18], the user's head and neck rest on the thinner cushion 1 while the arm rests on the thicker cushion 2, the two cushions being joined by the connecting means 3a.

[0124] It is well known that the semi-sitting position alone has an analgesic effect. It is used, among other things, in post-operative situations. Thus, this use of the semi-sitting support device meets a frequent need for which few satisfactory solutions exist, for users who wish, for example, to relieve shoulder tension.

[0125] Also, if the user wishes to lie on their side in the anatomical position known as lateral decubitus, the support device offers just as many advantages. Indeed, in this position and without such a support device, the arm naturally presents a large horizontal adduction angle of the shoulder joint yO, as illustrated in [Fig. 15], whereas in [Fig. 16] it can be seen, for example, that by using two identical but partially overlapping cushions 1, the user can considerably reduce said horizontal adduction angle, here with a value yl much lower than yO.

[0126] It is easily understood that this detailed description relates to particular examples of realization and implementation of the present invention, but that in no case does this description have any limiting character to the object of the invention; on the contrary, its objective is to remove any possible imprecision or misinterpretation of the following claims.

[0127] Similarly, the reference signs placed in parentheses in the following claims are in no way intended to be limiting; these signs are solely intended to improve the intelligibility and understanding of the following claims and the scope of the protection sought.
