Description

  The present invention relates to a lumbar supporter that is attached to the waist in order to reduce the burden on the lumbar region at the time of back pain or prevention of back pain.

  Today, there are a large number of people who are worried about the waist, and various back supporters and corsets are manufactured, sold, and used for reducing or preventing low back pain during sports or daily activities. These lumbar supporters and corsets are wrapped around the torso of the human body with a strong force, and maintain a stable posture that does not overwhelm the lumbar spine due to the strong compression force in the waistline direction. It reduces the burden on the spine and relieves pain and anxiety.

  For this reason, a relatively firm material is used for these waist supporters and corsets. In addition, when the symptom is severe, the affected part may be forcibly fixed using a cast or the like. This alleviates the pain by limiting the motion that causes the pain.

  As these waist supporters and corsets, as disclosed in Patent Document 1, surface fasteners can be provided at both ends of a belt-like belt made of a single elastic material, and a pad or the like can be attached to a predetermined part of the elastic member. In general, a device having a waist holdability is used. In addition, as disclosed in Patent Document 2 in order to further increase the tightening force and holding force, there is a medical corset in which a lumbar fixation band that holds the lumbar part and a pelvic fixation band that holds the pelvis are integrally connected at the lumbar part. Proposed. In addition, as disclosed in Patent Documents 3 and 4, as a supporter for the waist that enhances the holding effect of the waist and is easy to wear, a main belt as a supporter and a secondary belt that increases the holding power of the main belt are provided. There is also a supporter that is securely attached to the waist.

In addition, as disclosed in Patent Document 5, as a corset with a structure that further prevents displacement and enhances the holding effect of the waist part, the upper belt part wound around the waist part and the intermediate belt part below it are connected at the center part. A corset is also proposed in which a pair of lower bands surrounding the pair of thighs are provided continuously from the middle band.

  In the case of the conventional supporters and corsets described above, the posture is fixed and the pain in the lower back is reduced by tightening the entire circumference of the waist from the abdomen to the lower back with a strong compression force. At this time, since the soft abdomen is tightened with a strong force by the belt part wound around the waist, the discomfort due to the pressure on the abdomen is strong, and breathing difficulty and loss of appetite are often caused.

  On the other hand, as a method of fixing without a feeling of pressure, there is fixing with a cast, but in this case the waist is fixed with a hard cast, so the abdomen's tightness is somewhat small, but the body is restrained over a wide range, so the operation is significantly limited This is more uncomfortable for the wearer.

  The present invention has been made in view of the above-mentioned background art, and an object thereof is to provide a waist supporter that reduces the tightening force of the abdomen and has a comfortable wearing feeling.

  In order to achieve the above object, the present invention gives the stress due to tightening to the lumbar portion of the back and the left and right iliac portions which are part of the pelvis, and tightens the waist using the hard bone. It is what I did. That is, a support member is disposed on the left and right iliac and lumbar parts on the waist belt for wrapping around the lumbar part. As a result, the stress at the time of wearing and tightening is concentrated on these three members, and as a result, the pressure applied to the abdomen is reduced.

  The present invention relates to a belt-like waist belt wound around a person's waist, a waist support member provided at the inner center of the waist belt and abutting against the person's lumbar vertebra, and the inside of the waist belt It is a lumbar supporter provided with a pair of side support members that are provided on both sides and abut against a pair of left and right iliac portions on the side surface of a person's waist.

  Further, at least one of the waist support member and the side support member is provided so that the position thereof can be adjusted. In addition, the side support member is formed with a recess at the center, and the periphery of the recess is brought into contact with the iliac portion so as to surround the iliac spine.

  Further, the lumbar support member is formed such that a portion in contact with the upper portion of the lumbar portion is thicker than a portion located under the lumbar portion. Moreover, the said waist | hip | lumbar part support member and the said side part support member have a shock absorptivity.

  An anti-slip portion is formed inside at least one of the waist belt, the waist support member, and the side support member.

  The waist belt is provided with a holding member that covers at least one of the hip joint and the thigh. The waist belt may be provided with a reinforcement belt wound around the waist on the side thereof.

  The lumbar supporter according to the present invention includes a lumbar support member that abuts against a lumbar portion and a pair of side support members that abuts against a pair of left and right iliac portions on a lumbar belt wound around the lumbar region. The waist belt is tightened so as to cover two points on the left and right iliac parts and one point facing the lumbar vertebrae. When worn, the stress due to the tightening is concentrated on these three parts, and the pressure on the abdomen Is greatly reduced.

  Further, by providing side support members that contact the left and right iliac portions so that the position can be adjusted, and by adjusting the contact position and arranging the side support members on the abdominal side, the feeling of pressure can be further eased. In particular, by forming a recess in the central part of the side support member, this recess is brought into contact with the iliac spine to prevent positional displacement of the support member, and extreme stress concentration on the iliac spine is prevented. ease.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 5 show a first embodiment of the present invention. As shown in FIG. 1, a waist supporter 10 of this embodiment includes a belt-like waist belt 11 formed of a stretchable knit fabric. The position of the side support member 12 disposed on the back side of the waist belt 11 on the left and right iliac portions on the left and right sides of the waist belt 11 and the position of the waist support member 13 disposed on the portion contacting the lumbar portion of the back are adjusted. It is provided freely.

  The side support member 12 is applied to a position of the iliac 20 facing the iliac spine 20a in the cross section of the human waist part w shown in FIG. 5 and receives the tightening force of the waist belt 11 by the iliac 20. . The lumbar support member 13 is provided corresponding to the lumbar vertebra 21 on the back and supports the lumbar vertebra 21.

The side support member 12 and the lumbar support member 13 disposed on the iliac part and the lumbar part on the left and right sides of the lumbar part need to be hard enough not to be crushed by the tightening force of the waist belt 11. Problems such as hitting also occur. Therefore, as a material, an appropriate bend that does not buckle or collapse against the tightening force of the waist belt 11 such as a three-dimensional fabric such as a soft resin, hard rubber, foamed resin, and double raschel fabric using monofilament yarn. A member having hardness, thickness and elasticity is suitable. For example, a low resilience foam made of a crosslinked foam of styrene elastomer, a foamed resin made of ethylene vinyl alcohol (hereinafter referred to as EVA) or the like can be used with a predetermined thickness. These materials, 25% compressive hardness test value by JISK6767 is, in the styrene-based elastomer include the 2.6 N ^/ cm 2, the EVA 4.02N / cm ^2, side support members 12 and lumbar support member 13 Suitable for Moreover, when using a too hard raw material, such as a metal and a hard plastic, what shape | molded the member in the shape of the human body previously may be used.

  A surface fastener (not shown) is attached to the back surfaces of the side support member 12 and the waist support member 13, and is provided so that it can be attached to an arbitrary position of the surface fastener of the waist belt 11.

  A male member of the hook-and-loop fastener 14 is provided on the back surface of one end portion of the waist belt 11 and is provided so as to be attached to the cloth on the surface of the other end portion of the waist belt 11. Further, as shown in FIG. 2, the outer surface of the waist supporter 10 is a reinforcing belt made of a rubber band or the like that reaches both sides of the abdomen from the back part through both sides and is fixed to the waist belt 11 at both ends. 15 is provided.

  The thicknesses of the side support members and the 12 lumbar support members 13 arranged on the left and right iliac portions and the lumbar vertebra may be selected according to the purpose of use, the use environment, and the like. For example, the thickness is about 10 to 30 mm. Is preferable. This creates a space in the abdomen and removes the feeling of pressure.

  Further, by using a material having a high impact absorbing power as the side support member 12 and the waist support member 13, it is possible to prevent fractures and injuries such as the iliac bone and the tailbone during a fall. As the material having a high impact absorbing power, the low-rebound soft foam of the styrene elastomer and the EVA foamed resin are suitable. The impact absorbability expected as a material for the side support member 12 and the waist support member 13 of the present invention is preferably 50% or more in terms of impact absorption.

  Further, the side support member 12 applied to the left and right iliac portions may feel pain in this portion because stress concentrates on the iliac crest, in particular, the iliac spine 20a. Therefore, by placing the center of the side support member 12 in a concave shape and arranging the iliac spine 20a so as to enclose the iliac spine 20a by the recess 12a, the stress is distributed throughout the iliac portion, and the pain of the iliac spine 20a is alleviated. The

  Furthermore, the slippage of the waist belt 11 can be stopped by applying anti-slip processing or treatment to the inside of the waist belt 11, preferably the buttocks. As an example of the non-slip processing / treatment, other methods such as printing or sewing a resin having an anti-slip effect are possible. Non-slip processing / processing may also be performed on the human body side surfaces of the side support member 12 and the waist support member 13.

  The lumbar support member 13 disposed on the back lumbar vertebra is formed in an inverted trapezoidal shape in the mounted state, and is thicker on the upper side and thinner in the downward direction. Thereby, the member applied to the lumbar part is pressed more strongly against the lumbar part, the sense of stability of the lumbar part is further increased, and the low back pain prevention effect can be enhanced.

  Further, in order to reduce heat and stuffiness during wearing, the side support member 12 and the lumbar support member 13 disposed in the left and right iliac parts and the lumbar vertebra part may be provided with holes for ventilation and the like. In addition, if a three-dimensionally structured fabric such as a double raschel fabric is used, higher breathability can be provided.

  In the lumbar supporter 10 of this embodiment, the side support member 12 and the lumbar support member 13 which are arranged so as to contact the iliac part and the lumbar part on the left and right sides of the lumbar side face the stress when tightened in the mounted state. While being distributed to the side support member 12 and the lumbar support member 13 arranged in the bone part and the lumbar part, it concentrates on these three parts, and as a result, the pressure applied to the abdomen is reduced.

  Further, when the side support members 12 applied to the left and right iliac portions are arranged not on the body side but on the abdomen side as much as possible, the waist belt 11 supports the left and right side support members 12. Lifted and floated from the abdomen. Thereby, the pressure of the abdomen can be further reduced.

  Furthermore, since the tightening stress due to the waist belt 11 is effectively concentrated on the three members corresponding to the left and right iliac bones 20 and the lumbar vertebra 21 on the back, the waist belt 11 covering the waist belt 11 is relatively highly stretchable. A thin and flexible material may be used. By using such a material, it is possible to enhance the fit to the body and at the same time reduce the feeling of tightening.
