Description

Title of the invention: Posture correction device

[0001] The present invention relates to a posture correction device.

[0002] Such a posture correcting device aims to provide a user using the posture correcting device with a posture correction effect at the level of the user's upper back in order to prevent the user from experiencing pain at this level due to poor posture.

[0003] Known posture correcting devices are, for example, in the form of a closed elastic textile band. When worn, the band passes behind the user's neck, around their shoulders, and then under their armpits. Devices consisting of a positioning strap around the user's abdominal area and shoulder straps passing around the user's shoulders are also known. In these devices, the shoulder straps are either inelastic or elastic.

[0004] Known posture correcting devices are not comfortable and do not allow for easy modulation of the corrective force applied by the posture correcting device. In particular, it is not possible to eliminate this force without removing the posture correcting device.

[0005] One of the aims of the invention is to overcome these drawbacks by offering a comfortable posture corrector device that is easy to wear and applies an adjustable correction force.

[0006] To this end, the invention relates to a user posture correction device comprising: - a positioning strap designed to extend around the user's torso in a transverse direction, said positioning strap comprising a front part and a back part, - a first shoulder strap comprising a front part extending in an upward direction, substantially perpendicular to the transverse direction, between a first end, fixed to a first edge of the front part of the positioning strap, and a second end opposite the first end, and a dorsal part extending between a first end fixed permanently to the second end of the front part and a second end fixed in an adjustable and reversible manner to the front part of the positioning strap, - a second shoulder strap comprising a front portion extending in the direction of elevation between a first end, fixed to a second edge of the front portion of the positioning strap, opposite to the first edge in the transverse direction, and a second end opposite the first end, and a dorsal part extending between a first fixed end remaining at the second end of the front part and a second end fixed in an adjustable and reversible manner on the front part of the positioning strap,

[0007] the front parts of the first shoulder strap and the second shoulder strap being substantially inelastic and the back parts of the first shoulder strap and the second shoulder strap being elastic and crossing once between their first end and their second end.

[0008] The shoulder straps of the posture corrector device according to the invention comprise an inelastic front section and an elastic back section. The posture corrector device allows the force to be localized to the user's back, particularly where the back sections cross, without exerting uncomfortable pulling force on the front of the user's shoulders. Furthermore, the adjustable and reversible attachment of the back section of the shoulder straps to the fitting strap allows the corrective force exerted by the posture corrector device to be easily modulated, or even eliminated, without having to remove the device. Thus, the user can adjust the corrective force throughout the day without having to put on and take off the posture corrector device.

[0010] Other aspects and advantages of the invention will become more apparent upon reading the following description, given solely by way of non-limiting example, and made with reference to the accompanying drawings in which:

[0011] [Fig-1] - [Fig. 1] is a schematic perspective representation of part of a posture correction device according to the invention,

[0012] [Fig.2] - [Fig.2] is a schematic front view representation of the frontal part of the posture correcting device of [Fig.1] worn by a user,

[0013] [Fig.3] - [Fig.3] is a schematic front view representation of part of the front part of the strap for setting up the posture correcting device of [Fig.1],

[0014] [Fig.4] - [Fig.4] is a schematic side view of the front and back parts of the posture correcting device of [Fig.1] worn by a user, and

[0015] [Fig.5] - the [Fig.5] is a schematic front view representation of the dorsal part of the posture correcting device of the [Fig.1] worn by a user.

[0016] With reference to [Fig.1], a posture correcting device 1 is described, essentially comprising a positioning strap 2, a first shoulder strap 4 and a second shoulder strap 6.

[0017] The positioning strap 2 is arranged to encircle the abdomen of a user, for example by passing under their chest as shown in [Fig. 2]. For this purpose, the positioning strap 2 extends in a transverse direction T and is arranged to close upon itself, encircling the user's abdomen. The positioning strap 2 is, for example, made of a single piece of textile material, for example, substantially inelastic. By substantially inelastic, it is understood that the length of the positioning strap 2, measured in the transverse direction T, remains substantially constant when the positioning strap 2 is stretched in the transverse direction T. For example, during such stretching, the extensibility of the positioning strap is less than or equal to 10%, i.e., the positioning strap cannot be stretched beyond 10% of its initial length.The positioning strap 2 defines an inner face 8, applied against the user's skin when the posture corrector device 1 is worn, and an outer face 10, opposite the inner face 8, and facing outwards when the posture corrector device 1 is worn. The positioning strap 2 is, for example, made of back-to-back astrakhan, that is, by forming a textile complex, for example by bonding, of two knits or fabrics having loops on their outer face, opposite their bonded face. The knits or fabrics can be made of synthetic, natural, or artificial materials.

[0018] The positioning strap 2 extends, along the transverse direction T, between a first fastening end 12 and a second fastening end 14 which can be fixed to each other and / or to the outer face 10 of the positioning strap 2 in an adjustable and reversible manner. By "adjustable and reversible manner" it is meant that the fixing between the first and second fixing ends 12 and 14 can be made and unmade at will and that the position of these ends relative to each other can be modified so that the tightening exerted by the positioning strap 2 on the user's abdomen can be adjusted. In order to allow this adjustable and reversible fixing, the first and second fixing ends 12, 14 include, for example, on the inner face 8 of the positioning strap 2, a reversible fixing device 15 (shown in dashed lines in the Figs.2 and 3), for example, formed by a pad of hooks, and the outer face 10 of the positioning strap includes a complementary fastening device for the reversible fastening device, for example, loops or other hooking material, onto which the hooks can catch to secure the strap. In one embodiment, the entire outer face 10 of the positioning strap 2 is made with such a complementary fastening device so that a reversible fastening device can be reversibly attached anywhere on the outer face 10 of the positioning strap. In one embodiment, the removable strap is also cuttable to allow its length, measured along the transverse direction T, to be adjusted to the user's body shape.In this case, the reversible fastening device 15 is removably fixed to the inner face of the positioning strap 2 so that its position can be adapted according to the length of the positioning strap 2.

[0019] The positioning strap 2 defines a front part 16, shown in [Fig.2], and a back part 18, shown in [Fig.5].

[0020] The front portion 16 is intended to extend over the front of the user's body, passing, for example, under their chest, as shown in [Fig. 2]. When the first and second attachment ends 12, 14 are fixed, the front portion 16 extends in the transverse direction between a first edge 20 and a second edge 22, each of which is intended to extend substantially over one of the user's armpits, offset from it in an elevation direction Z, substantially perpendicular to the transverse direction T, as more particularly visible in [Fig. 4] for the first edge 20. According to the embodiment shown in Figs. 2 and 3, the front portion 16 is formed by a first section 24 extending from the first edge 20 to the first attachment end 12 and by a second section 26 extending from the second edge 22 to the second attachment end 14.When not fixed to each other, the first and second sections 24, 26 allow the positioning strap 2 to be placed around the user's abdomen, the positioning strap 2 then being held and adjusted around the abdomen by fixing the first and second sections 24, 26 via the . First and second fastening ends 12, 14. To allow this fastening, one of the first and second sections 24, 26 includes, for example, a through-hole allowing the other section to pass through, as shown in [Fig. 3]. Thus, the inner faces 8 of the two fastening ends 12, 14 are positioned opposite the outer face 10 of the first and second sections 24, 26 and can be fastened to them. In one embodiment, only the section without a through-hole is cuttable to adjust the length of the positioning strap, and the removable reversible fastening device 15 is also provided on this cuttable section.

[0021] The dorsal portion 18 of the positioning strap is designed to extend against the user's back in line with the frontal portion 16. As shown in [Fig. 5], the dorsal portion 18 extends from the first edge 20 to the second edge 22 of the frontal portion 16 so that the positioning strap 2 completely encircles the user's body when the posture corrector device 1 is worn. According to the embodiment shown in the figures, the dorsal portion 18 is formed from a single section. However, according to one alternative, the first and second attachment ends and the first and second sections could be provided within the dorsal portion 18, the frontal portion 16 then being formed from a single section and the positioning strap attaching to the user's back instead of under their chest, as described previously.

[0022] The first shoulder strap 4 comprises a front part 28 and a back part 30.

[0023] The front portion 28 extends substantially along the elevation direction Z between a first end 32, attached to the positioning strap, and a second end 34, opposite the first end 32 and intended to extend over the user's shoulder when the posture corrector 1 is worn. More specifically, the first end 34 of the front portion 28 of the first shoulder strap 4 is attached to the first edge 20 of the front portion 16 of the positioning strap 2. By "attached," it is understood that the attachment between the first end 32 and the positioning strap 2 is not reversible and cannot be undone under normal conditions of use of the posture corrector 1. In one embodiment, the first end 32 is permanently attached to the positioning strap, for example, by sewing between the front portion 28 of the first shoulder strap 4 and the positioning strap 2.However, according to a particularly advantageous embodiment, the first end 32 slides on the positioning strap around the first edge 20 of the front part 16 so that the position of the first shoulder strap 4 is adjustable relative to the positioning strap 2 in order to adapt to the user's morphology. It should be noted. that this sliding is permitted without however allowing the first end 32 of the positioning strap 2 to be detached.

[0024] When the posture corrector device is worn, the front part 28 of the first shoulder strap 4 extends from the positioning strap 2 to one shoulder of the user, passing along one side of the user's chest, as particularly visible in Figs. 2 and 4. The front part 28 is, for example, arranged to cover most of the shoulder so that the second end 34 of the front part 28 extends over a rear part of the shoulder, as particularly visible in [Fig. 5].

[0025] The front portion 28 is made of a substantially inelastic material. Thus, as described above, the front portion 28 is substantially inextensible when stretched in the direction from the first end 32 to the second end 34. For example, during such a stretch, the extensibility of the front portion 28 of the first shoulder strap 4 is less than or equal to 10%. The front portion 28 of the first shoulder strap 4 is, for example, made of brushed mesh or back-to-back astrakhan, for example, from synthetic, natural, or artificial textile materials.

[0026] According to one embodiment, the front part 28 of the first shoulder strap 4 is made of a material that does not irritate the skin, at least on its inner face, which improves the comfort of the posture corrector device 1 by preventing the front part 28 of the first shoulder strap from irritating the user wearing this posture corrector device 1. Alternatively, the front part 28 may further include a lining, extending at least on the inner face of the first shoulder strap 4 so as to be applied against the user's body when the posture corrector device is worn.

[0027] The dorsal part 30 of the first shoulder strap 4 extends in a direction inclined relative to the elevation direction Z between a first end 36 permanently fixed to the second end 34 of the front part 28 and a second end 38 fixed in an adjustable and reversible manner on the positioning strap 2. By "inclined direction", it is understood that the dorsal part 30 forms a non-zero angle with the elevation direction Z when the posture corrector device 1 is worn as shown in [Fig. 5], so that the dorsal part 30 of the first shoulder strap 4 extends from the shoulder opposite the first edge 20 of the front part 16 at the level of its first end 36 to the vicinity of the second edge 22 of the front part at the level of its second end 38.The second end 38 of the dorsal part 30 is more particularly fixed in an adjustable and reversible manner on the front part 16 of the positioning strap 2 in the vicinity of the second edge 22. By in the vicinity of the second edge 22, we mean more particularly that the . The second end 38 of the dorsal section 30 can be attached to the front section 16 of the positioning strap 2 at any point on either of the first or second sections 24, 26 of the front section 16 of the positioning strap 2 when the front section 16 is formed in two sections, as described previously. To allow this adjustable and reversible attachment, the inner face of the second end 38 of the dorsal section 30 is, for example, provided with a reversible attachment device capable of cooperating with the complementary attachment device provided on the outer face 10 of the front section 16 of the positioning strap 2. The reversible attachment device provided on the dorsal section 30 is, for example, of the same type as that provided on the attachment ends 12, 14 of the positioning strap 2.

[0028] The back section 30 is made of an elastic material. By "elastic," it is understood that the back section 30 is extensible, at least along its length from the first end 36 to the second end 38, when a force tending to stretch it is applied, and that the back section 30 returns to its initial length when this force ceases to be applied. For example, during such stretching, the extensibility of the back section 30 of the first shoulder strap 4 is greater than or equal to 50% of its initial length, that is to say, the back section 30 can be stretched beyond at least 50% of its initial length. The back section 30 of the first shoulder strap 4 is, for example, made of a narrow elastic band composed of polyamide and elastane.

[0029] According to one embodiment, the dorsal part 30 is cuttable on the side of its second end 38 and the reversible fastening device is removably fixed in the vicinity of this second end 38 so that the length of the first shoulder strap and the position of the reversible fastening device are adaptable to the morphology of the user.

[0030] The permanent attachment between the second end 34 of the front part 28 and the first end 36 of the back part 30 of the first shoulder strap 4 is obtained for example by sewing, by welding or by any other suitable assembly between the front part 28 and the back part 30.

[0031] The second shoulder strap 6 is, for example, identical to the first shoulder strap 4, that is to say, it comprises a substantially inelastic front portion 40 and an elastic back portion 42. The front portion 40 extends along the elevation direction Z between a first end, permanently fixed to the second edge 22 or, preferably, sliding around the second edge 22 of the front portion 16 of the positioning strap 2, and a second end 46, opposite the first end and intended to extend over the user's shoulder opposite the second edge 22 of the positioning strap 2 when the posture corrector device 1 is worn. The back portion 42 extends at an angle by The relationship to the elevation direction Z is between a first end 48, permanently fixed to the second end 46 of the front section 40, and a second end 50, adjustablely and reversibly fixed to the positioning strap 2, near the first edge 20 of the front section 16 of the positioning strap 2. More specifically, the second end 50 is adjustablely and reversibly fixed to the other of the first and second sections 24, 26 of the front section 16 of the positioning strap 2 when the latter is made in two sections, as described above. For other characteristics of the second shoulder strap 6, reference may be made to the description of the first shoulder strap 4.Thus, it is particularly important to note that the dorsal part 42 of the second shoulder strap 6 is, for example, cuttable on the side of its second end 50 and that the reversible fastening device is removably fixed in the vicinity of this second end 50 so that the length of the second shoulder strap and the position of the reversible fastening device are adaptable to the user's morphology.

[0032] It appears from the orientation of the dorsal parts 30,42 of the first and second shoulder straps 4, 6, that these cross once in the back of the user when the posture corrector device is worn, as more particularly visible in [Fig.5].

[0033] According to one embodiment, the back sections 30, 42 are engaged and cross within a support element 52 arranged to be applied against the user's back when the posture corrector device 1 is worn. Such a support element 52 comprises at least one pad extending onto the inner face of the first and second shoulder straps 4, 6 at the point where these shoulder straps cross, such that the pad is interposed between the crossing of the back sections 30, 42 and the user's back, the pad being applied against the user's back by the back sections 30, 42. The pad has, for example, a surface area of ​​at least 15 cm². The pad has, for example, a substantially circular shape, the periphery of which extends around the crossing of the back sections 30, 42, as more particularly visible in [Fig. 5].The pad is, for example, made of a substantially inelastic material, for example the same material as the positioning strap 2. According to one embodiment, the support element 52 further comprises an annular element 54 extending over the outer face of the dorsal parts 30, 42 around their intersection, and fixed to the pad between the dorsal parts 30, 42. For this purpose, the pad and the annular element 54 have, for example, the same contour, more particularly the same diameter. The annular element 54 extends around a central opening in which the dorsal parts 30, 42 of the first and second shoulder straps 4, 6 cross, as shown in [Fig. 5]. The pad and the annular element 54 define two pairs of loops 55 for the passage of the dorsal parts 30, 42. 42 of the first and second shoulder straps 4, 6. More specifically, the loops 55 of each pair of loops are diametrically opposed and extend along the inclined direction of each back section 30, 42 so that each back section 30, 42 is engaged in one of the pairs of loops, the back sections 30, 42 crossing between the loops 55, as shown in [Fig. 5]. This ensures the attachment of the support element 52 to the first and second shoulder straps 4, 6. It is also understood that the back sections 30, 42 can slide in the loops of the support element 52 so that the height of the support element 52 on the user's back can be adjusted.

[0034] However, in order to limit this movement towards the user's shoulders, the posture corrector 1 comprises, in one embodiment, stop elements 56 extending around the dorsal portions 30, 42 of the first and second shoulder straps 4, 6 between the first ends 36, 48 of the dorsal portions 30, 42 and the support element 52. Each dorsal portion 30, 42 is thus engaged in a stop element 56 which is positioned between the support element 52 and the user's shoulders when the posture corrector 1 is worn. The position of each stop element 56 is, for example, adjustable on the dorsal portion 30, 42 around which the stop element 56 extends so as to be adapted to the size of the user wearing the posture corrector 1.

[0035] According to one embodiment, the posture correcting device 1 further comprises a first loop 58 and a second loop 60, in which the dorsal part 30 of the first shoulder strap 4 and the dorsal part 42 of the second shoulder strap 6 are respectively engaged in the vicinity of their second ends 38, 50. More particularly, the dorsal part 30 of the first shoulder strap 4 passes through the first loop 58 between the support element 52 and its second end 38, which is fixed in an adjustable and reversible manner to the front part 16 of the positioning strap 2. Similarly, the dorsal part 42 of the second shoulder strap 6 passes through the second loop 60 between the support element 52 and its second end 50, which is fixed in an adjustable and reversible manner to the front part 16 of the positioning strap 2.The first loop 58 is fixed, for example by sewing, to the outer face 10 of the positioning strap 2 at the second edge 22 of the front part 16 and / or to the outer face of the front part 40 of the second shoulder strap 6 at its first end. The second loop 60 is fixed, for example by sewing, to the outer face 10 of the positioning strap 2 at the first edge 20 of the front part 16 and / or to the outer face of the front part 28 of the first shoulder strap 4 at its first end 32.

[0036] The operation of the posture correction device 1 will now be described.

[0037] The user puts on the posture corrector device 1 by placing the open positioning strap 2 around their abdomen under their chest and passing their arms through the first and second shoulder straps 4, 6 so that the front parts 28, 40 of these straps pass along the user's chest, as shown in Figs. 2 and 4, and the back parts 30, 42 cross over the user's back, as shown in [Fig. 5]. The user can then close the positioning strap, for example by passing one of the first and second sections 24, 26 through the opening in the other section and securing the first and second fastening ends 12, 14 to the outer face 10 of these sections 24, 26, as shown in [Fig. 3].

[0038] It should be noted that, thanks in particular to the support element 52 and the first and second loops 58, 60, the crossing of the back sections 30, 42 is maintained even when the posture corrector 1 is not being worn. Thus, when the user puts on the posture corrector 1, they do not need to manually position the back sections 30, 42 so that they cross behind their back. When the user puts on the posture corrector 1, the back sections 30, 42 are already correctly positioned and the support element 52 is pressed against the user's back.

[0039] The posture-correcting effect is then applied as soon as the second ends 38, 50 of the dorsal parts 30, 42 of the first and second shoulder straps 4, 6 are fixed to the front part 16 of the positioning strap. Indeed, when this fixing is ensured, the dorsal parts 30, 42 exert a traction on the user's back, represented by the arrows F in [Fig. 5], which tends to pull the shoulders backward and toward each other thanks to the crossing of the shoulder straps in the user's back. By providing the front parts 28, 40 of the first and second shoulder straps 4, 6 to be substantially inelastic, it is ensured that the traction force is concentrated in the user's back where posture correction is needed, due to the elasticity of the back parts 30, 42, without exerting uncomfortable traction on the front of the body.The support element 52 allows the restoring force to be localized at the point where the dorsal sections 30 and 42 intersect, further enhancing the posture-correcting effect. In addition, the posture-correcting device allows the user freedom of movement, as the rigidity of the front sections of the first and second shoulder straps 4 and 6 does not impede such movements.

[0040] The posture-correcting effect can be more or less pronounced depending on the position of the attachment of the second ends 38, 50 of the dorsal parts 30, 42 of the first and second shoulder straps 4, 6. Indeed, the closer the second ends 38, 50 are attached to the center of the front part 16 of the positioning strap, the center being equidistant from the first and second edges 20, 22 of the part The more tension is exerted on the front part 16, the greater the traction on the user's back, thus accentuating the posture-correcting effect. Similarly, this effect can be reduced, or even eliminated, by attaching the second ends 38, 50 near or on the first and second edges 20, 22 of the front part 16 of the positioning strap 2, in order to release the tension exerted by the back parts 30, 42 of the first and second shoulder straps 4, 6. This adjustment can be made particularly easily by the user themselves, without requiring the intervention of a third party.

[0041] Thus, the user can choose to adjust the posture-correcting effect throughout the day according to their activities. This can be done without having to remove and put on the posture-correcting device 1, particularly when the user wishes to eliminate the posture-correcting effect.
