- a central
- Reference letters L and R stand for left and right even if it is clear that symmetric arrangement by exchanging right and left is equivalent. Moreover, in the figures buckle
elements buckle 5 and holes 6, even if it is clear that other types of buckles, or other means fastening the terminal portions to each other, can be used, as known in the art. For example, a closure system that shortens both terminal portions of the belt (toothed or clip type), can be provided - The waist belt according to
claim 1, wherein said central straight portion has a length that is comprised between 40% and 50% an overall length of said waist belt. - First and second
curved portions longitudinal extension 30, which can vary each for example between 15% and 20% an overall length of said waist belt, according to the wearer's anatomy. - As shown in
FIG. 3 , eachcurved portion concave portions 3′L and 3″L and 3′R and 3″R, respectively, having concavities opposite to each other. In particular,concave portions 3′L and 3′R are arranged consecutive tocentral portion 2 and have concavities of are facing towardsterminal symmetry plane 400, whereasconcave portions 3″L and 3″R are arranged consecutive toterminal portions central symmetry plane 200. - Preferably, the curvilinear course of
side portions concave portions 3′L and 3″L and 3′R and 3″R which are circumference portions of similar radius and angular development of less than 90°. - With reference to
FIGS. 4 and 5 , theimproved waist belt 1 is particularly suitable for being combined with garments, for example trousers T, but also, as clear to a person with ordinary skill in the art, to skirts and the like, all of the type with belt loops K, to support them at the waist when worn by a wearer W. - As shown in
FIGS. 4 and 5 , centralstraight portion 2 has a predetermined length 20 (FIG. 1 ) and is configured to cover a wearer's back WB. -
Curved side portions central portion 2, and have specular developments sufficient to surround an area WH of the hips of wearer W. They have curvilinear trends suitable for following the iliac crests of the wearer, so that an arrival level, namelyterminal plane 400, of saidside portions central plane 200, of said central rearrectilinear portion 2, for the same height distance ΔH ofFIG. 2 .Curved side portions FIG. 1 ) that can vary, as indicated below. - The two
terminal portions side portions buckle 5 with tongue and holes 6, or equivalent means, suitable for mutually binding them to each other in a removable manner, in order to surround the pelvis WP of wearer W at the height of the pubic symphysis. - In
FIGS. 4 and 5 the shape ofwaist belt 1 on wearer W is shown, presenting double-curved side portions - Furthermore, it can be observed how
waist belt 1, engaged in the loops K of trousers T worn by wearer W, imposes to trousers T a deformation of the waist line of the garment, such that the front part WP is lower than the rear part WB, in accordance with the height distance ΔH betweencentral plane 200 ofcentral part 2 andterminal plane 400 ofterminal portions - According to the invention, with reference to
FIG. 6 and also toFIGS. 1, 4 and 5 , theelongation 30 ofcurved portions - More precisely, the central
straight portion 2 can have alength 20 that is configured to extend horizontally on the wearer's back WB between two wearer's pelvis PosteriorSuperior Iliac Spines 70, which are located at the specific height distance ΔH from the wearer'spubic symphysis 90 of the wearer's pelvis WP. Thelength 20 of the centralstraight portion 2 determines the starting point ofcurved portions FIG. 4 ), from which the firstconcave portions 3′R or 3′S, with downward concavity, start. - First
concave portions 3′R or 3′S are configured to start from wearer's pelvis PosteriorSuperior Iliac Spines 70 and rest on the respective wearer's iliac crests 75, so as to extend between a respective wearer's SuperiorPosterior Iliac Spine 70 and the wearer's SuperiorAnterior Iliac Spines 80 so that the wearer's intersection of the median frontal/coronal plane with the iliac crest, which cuts the human body in two equal halves anterior and posterior, falls within the concave portions. - After or anteriorly such wearer's intersection falls
connection point 300 ofbelt 1, between firstconcave portions 3′R or 3′S and secondconcave portion 3″R or 3″S, with upward concavity, which configured to rest on the respective wearer's anterior inferioriliac spines 85 and to land atterminal plane 400, which is at the same height as the wearer'spubic bone 90 and anteriorly to the pubic bone of the wearer's pelvis WP (see alsoFIGS. 4 and 5 ). - The two terminal
rectilinear portions respective lengths belt buckle elements pubic bone 90 of the wearer's pelvis WP. - The choice of the coincidence of first and second
concave portions 3′R or 3′S, and 3″R or 3″S, with wearer's anatomic references from 70 to 85 permits to identify dimensional values of the different parts of thebelt 1, in order to obtain a positioning of the belt on the wearer's bone contours, and specifically on the male or female pelvis. - For example, for a male individual of medium height 181 cm, that is the median height of the 21-year-old European man, starting from the aforementioned anatomical references for the sizing of the parts of the belt, in the case of an individual male of medium height 181 cm in erect position, there is a height ΔH: 8.6 cm from the line joining the two Posterior Superior Iliac Spines and the pubic symphysis of the pelvis. Such value of ΔH can be considered as reference value for sizing of the belt for a male wearer.
- Taking into account that this height may vary according to body size and sex, it can be expected that ΔH0=8.6 cm±4 cm or 4.6<ΔH0<12.6 cm. Furthermore, taking into account that the rear
rectilinear portion 2 can also be suitable for providing lumbar support, an increase in the maximum values of 6 cm can be envisaged: 4.6<ΔH0<18.6 cm. - As for a female model, being the median height in the adult female population 167 cm and the female pelvis, in the fertile phase of a woman's life, undergoes functional anatomical modifications that reduce ΔH up to a ratio of 5/7 compared to Male ΔH, the possible correlation for a female wearer we have 3.2<ΔH0<13.3 cm
- Then, a linear correlation is then possible between the difference in height of the two planes (central and terminal) and the height of the wearer to maintain the positioning of the belt on the bony contours of the pelvis, provided by the following formula:
-
ΔH=H1/H0*ΔH0 -
- being H0=181 cm for men and 167 for women
- and
- 4.6<ΔH0<18.6 cm for a male wearer
- 3.2<ΔH0<13.3 cm for a female wearer.
- In this way, a range of ΔH is obtained for an individual which is useful for this precise purpose of obtaining a positioning of the belt on the bony contours of the pelvis, and it is possible to determine the ideal size of the belt according to the invention for an individual male, adult female or for children.
- The following is an example of sizing for male wearers.
-
Male Height H1 ΔH, for ΔH0 = 8.6 cm 88 4.2 120 5.7 158 7.5 167 7.9 181 8.6 193 9.2 207 9.8 215 10.2 - The following is an example of sizing for female wearers.
-
Female Height H1 ΔH, for ΔH0 = 6.1 cm 88 3.2 120 4.4 158 5.8 167 6.1 181 6.6 193 7.1 - Preferably, ΔH is independent of the body mass index, that is, it is the same for two individuals of the same height.
- As a result of the value of ΔH the inclination of the curved portions will determine with greater slopes of
portions 3R and 3S in smaller sizes. - In the above examples, a specific ΔH0 has bee selected. Of course, ΔH0 can vary in case of specific anatomy and needs. For example, an analysis of functional anatomy can be followed by a practical evaluation of the creation of
specific belts 1, also considering the large-scale production process with die cutting, as indicated below. - Concerning the
length terminal portions n 5 holes spaced each no 2 cm) allowing a range of shortening / lengthening of the belt worn by ±4 cm. - For such applications a larger ΔH (up to 20 cm) can be useful, for providing a lumbar support by the
central portion 2. - The waist belt of the invention offers the wearer perceptible advantages, besides an elegance similar to a normal belt it provides high stability and full support of the garments, high adherence to the body without determining high forces when sitting.
- The evidence of such reduced forces is shown in
FIGS. 7 and 8 . In particular, positioning force sensors under the belt at the intersection point of the median frontal/coronal plane haven been applied on abelt 1 according to the invention and to straight belt of known art, the belts of a same leather band material ofthickness 3 mm and width of 40 mm and tightened at a same grade. - In
FIGS. 7 and 8 a simple test measurement of the effort when moving from a sitting position to a standing position and again sitting and standing is shown for abelt 1 according to the invention and for a belt of known art, respectively on a same patient. - In
FIG. 7 , the force that thebelt 1 according to the invention exerts on the hip region compressing the body was about 6N when standing, peaking to maximum 12N when sitting. On the other hand, as shown inFIG. 8 , the force that a straight belt of known art exerted on the hip region compressing the body when sitting was very high and about 40N, and when standing it was about 10N. The test showed that whereas when standing the difference between the forces exerted by the two belts is similar, when sitting the traditional straight belt determines much higher forces than thebelt 1 according to the invention. - Therefore, using the belt according to the invention, owing to reduced effort in the sit-to-stand movement with respect to straight belts of prior art can provide positive effects on low back pain and functional capacity in gymnastic exercise like sit-to-stand, squats, lunges. In particular, the belt can be applied in the elderly or in patients affected by neurodegenerative diseases for improving walking and preventing falls.
- In the embodiment shown in
FIG. 9 , semi-rigid reinforcingstrips 50 can be provided associated withcurved portions central portion 2 and theterminal portions side portions - Advantageously, it can be provided that at least the
side portions improved waist belt 1 consist of two superimposed layers of material, in a way not shown in the figures but obvious for a person with ordinary skill, so as to be able to house the reinforcingstrips 50 interposed between said two layers. - In a preferred constructive solution, the reinforcing
strips 50 comprise consecutive sectors mutually articulated with hinges (not shown), so that the overall flexibility of theaforementioned side portions waist belt 1 to wrap around the wearer's body W, remains almost equivalent to that of said centralrear portion 2 andterminal portions waist belt 1 itself. - The belt according to the invention can be used also for medical or sports performance applications. In fact, the various embodiments described above and depicted in the drawings, the belt according to the invention can support the wearer while sitting and can provide an aid or remove a constriction/limitation in flexion-extension movements of the trunk on the legs as well as in the activity of getting up and sitting down (sit-to-stand.
- Moreover, the creation of rigid, elastic or “stiff”
curves - The stability of the position of the belt in the rear central point WB of
FIG. 4 bycentral portion 2 permits therefore improvement of human movement by monitoring with wearable sensors. - In the embodiment shown in
FIGS. 10-12 wearable sensors and effectors can be mounted tobelt 1 in order to exploit specific functionalities thereof. - In particular, with reference to
FIG. 10 , an inertial measurement unit sensor or IMU, or the like accelerometers, can be provided as 500. In fact, owing to the stability ofbelt 1 an improvement in the sensitivity of the IMU (inertial measurement units) has been experimented, - The
IMU sensor 500 or the like oncentral portion 2 ofbelt 1 for gait analysis in everyday life environments avoids the drawback the affects such type of sensors when applied to patients, since they require almost constant positioning of the accelerometer applied to the belt with respect to the body, thus reducing the amount of data processing necessary to “clean the signal”. - Furthermore, the waist belt of the invention lends itself to implementing IMUs for analysis of trunk movements: the rear part of the belt follows the flexion-extension movements of the trunk and the sensor positioning point is characterized by movements of greater amplitude than the traditional belt.
- Advantageously, the
IMU sensor 500 or the like oncentral portion 2 ofbelt 1 is connected to acontrol unit 510 by awireless connection 520, not described in detail since obvious to a person with ordinary skill. The control unit can be a dedicated unit or a mobile phone or tablet on which a dedicated app is run, that shows gait information to the wearer or to a doctor or assistant. - In a further possible embodiment, shown in
FIG. 11 , strain gauges orstretch sensors central portion 2,curved portions terminal portions Stretch sensors central chip 540 connected to acontrol unit 510 by awireless connection 520, not described in details since obvious to a person with ordinary skill. - As shown in
FIG. 12 , the two embodiments ofFIGS. 10 and 11 can be integrated to each other, and theIMU sensor 500 can also operate to transmit stretch signals coming fromstretch sensors sensors smartphone 500, through dedicated algorithms (sensors fusion algorithms), thus increasing the accuracy and completeness of the data, by dedicated programs or apps available on the market that can be easily implemented by a skilled person. - The possibility of applying different types of sensors to the
belt 1 according to the invention, owing to its stability on the wearer's body permits to achieve high advantages. Thebelt 1 with sensors as depicted inFIGS. 10-12 can be worn like a normal belt improving the compliance of patients or participants in scientific studies. - The belt of the invention can be made of classic leather, or other natural and synthetic materials.
- For example,
waist belt 1 can be made, like known belts, with said centralrear portion 2,side portions terminal portions - For example, from a
tanned hide 100 portion many waist belts can be obtained by a die cutting operation, as shown inFIG. 7 . In this way, the stiffness in the plane of the band material of the belt, for example tanned leather, is assured. - Alternatively, to die cutting, laser or CNC cutting of
portion 100 can be carried out. In particular, the shape ofbelt 1 permits high cutting efficiency. In fact,central portion 2 andcurved portions terminal portions adjacent belts 1, sincecentral portion 2 andcurved portions subsequent belt 1 substantially matches the space formed under eachcentral portion 2 andcurved portions previous belt 1. - A mechanical assembly of different sections can also be provided. For example, it is possible to provide that the aforementioned central
rear portion 2,side portions terminal portions - The proposed belt can be made without any difficulty according to the usual techniques of the art, in order to offer all the variations of material, color and aesthetics that the market requires.
- As it is easy to understand, the proposed belt can be produced with production costs substantially equivalent to those of a belt of the known art, so as to be able to offer it at prices that are not so different from the latter.
