中央腰当て帯部１の肉厚寸法ｔ1 （図７参照）を、５mm以上15mm以下に設定するとともに、膝掛帯部２の肉厚寸法ｔ2 を、２mm以上７mm以下に設定し、かつ、膝掛帯部２の肉厚寸法ｔ2 を、中央腰当て帯部１の肉厚寸法ｔ1 以下に設定する。中央腰当て帯部１の肉厚寸法ｔ1 が、５mm未満の場合、使用時の強度が不足する。即ち、耐久性が悪くなる。中央腰当て帯部１の肉厚寸法ｔ1 が、15mmを超える場合、中央腰当て帯部１が身体に密接状に変形しにくくなり、使用感が悪くなる。膝掛帯部２の肉厚寸法ｔ2 が、２mm未満の場合、適切な弾発復元力Ｆが得られない。即ち、弾発復元力Ｆが小さくなり過ぎる。膝掛帯部２の肉厚寸法ｔ2 が、７mmを超える場合、膝掛帯部２を膝Ｎに掛ける際、大きな力が必要になり、容易に膝Ｎに掛けることができない。膝掛帯部２の肉厚寸法ｔ2 が、中央腰当て帯部１の肉厚寸法ｔ1 を超える場合、使用感が悪くなる。 The wall thickness dimension t 1 of the central waist support band 1 (see FIG. 7) is set to 5 mm or more and 15 mm or less, and the wall thickness dimension t 2 of the knee rest band 2 is set to 2 mm or more and 7 mm or less. , the wall thickness t 2 of the rug band section 2, is set to be equal to or less than the thickness dimension t 1 of the central lumbar support belt part 1. The central waist wall thickness t 1 of the hit band section 1, if it is less than 5mm, insufficient strength at the time of use. That is, the durability is deteriorated. When the wall thickness dimension t 1 of the central waist support band portion 1 exceeds 15 mm, the central waist support band portion 1 is less likely to be deformed in close contact with the body, resulting in poor usability. Wall thickness t 2 of the rug band section 2, in the case of less than 2mm, not appropriate elastic restoring force F can be obtained. That is, the elastic restoring force F becomes too small. When the wall thickness dimension t 2 of the knee strap portion 2 exceeds 7 mm, a large force is required when the knee strap portion 2 is hung on the knee N, and the knee hang belt portion 2 cannot be easily hung on the knee N. Wall thickness t 2 of the rug band section 2, if it exceeds the thickness dimension t 1 of the central lumbar support belt portions 1, use feel is poor.

中央腰当て帯部１の幅寸法ｗ1 （図６参照）を、60mm以上 150mm以下に設定するとともに、膝掛帯部２の幅寸法ｗ2 を、40mm以上80mm以下に設定する。中央腰当て帯部１の幅寸法ｗ1 が、60mm未満の場合、適切に座位姿勢を矯正することができない。中央腰当て帯部１の幅寸法ｗ1 が、 150mmを超える場合、使用感が悪くなる。膝掛帯部２の幅寸法ｗ2 が40mm未満の場合、強度不足となる。膝掛帯部２の幅寸法ｗ2 が、80mmを超える場合、使用時に膝Ｎに配設するのに手間がかかる。 The width dimension w 1 of the central waist support band 1 (see FIG. 6) is set to 60 mm or more and 150 mm or less, and the width dimension w 2 of the knee rest band 2 is set to 40 mm or more and 80 mm or less. If the width dimension w 1 of the central waist pad portion 1 is less than 60 mm, the sitting posture cannot be properly corrected. If the width dimension w 1 of the central waist pad portion 1 exceeds 150 mm, the usability deteriorates. If the width w 2 of the blanket strip portion 2 is less than 40 mm, the insufficient strength. When the width dimension w 2 of the knee strap portion 2 exceeds 80 mm, it takes time and effort to dispose of it on the knee N at the time of use.

座位姿勢矯正ベルトは、ＪＩＳ Ｋ７３１２に規定されているＴＹＰＥ Ａ試験器を用いて測定される硬度が、Ａ３〜Ａ１０の弾性体から成る。ＪＩＳ Ｋ７３１２に規定されているＴＹＰＥ Ａ試験器を用いて測定される硬度が、Ａ３未満の場合、適切な弾発復元力Ｆが得られない。即ち、弾発復元力Ｆが小さくなり過ぎる。ＪＩＳ Ｋ７３１２に規定されているＴＹＰＥ Ａ試験器を用いて測定される硬度が、Ａ１０を越える場合、膝掛帯部２を膝Ｎに掛ける際、大きな力が必要になり、容易に膝Ｎに掛けることができない。 The sitting posture correction belt is made of an elastic body having a hardness of A3 to A10 as measured by using a TYPE A tester specified in JIS K7312. If the hardness measured using the TYPE A tester specified in JIS K7312 is less than A3, an appropriate elastic restoring force F cannot be obtained. That is, the elastic restoring force F becomes too small. If the hardness measured using the TYPE A tester specified in JIS K7312 exceeds A10, a large force is required when the knee strap 2 is hung on the knee N, and the knee N can be easily hung. I can't.

なお、本発明は、設計変更可能であって、例えば、中央孔部３を省略するも良い。また、側端孔部４を省略するも良い。また、中央孔部３の形状を、（左右方向にスリット状の）横長菱型等とするも良い。 The design of the present invention can be changed, and for example, the central hole 3 may be omitted. Further, the side end hole portion 4 may be omitted. Further, the shape of the central hole 3 may be a horizontally long rhombus (slit in the left-right direction) or the like.

以上のように、本発明は、弾性ゴム又は弾性エラストマーから成る一体成型弾性体であって、中央腰当て帯部１と、該中央腰当て帯部１の左右各々に連設された膝掛帯部２とを、有し、上記中央腰当て帯部１を使用者Ｕの背中Ｂ側に配設するとともに、上記膝掛帯部２を使用者Ｕの左右各々の膝Ｎに掛けて、弾発復元力Ｆにより座位姿勢を矯正するように構成したので、縫い目や継ぎ目が全く存在せず、耐久性が良い。特に、クロス状の使用状態（図３・図４参照）に於て、中央腰当て帯部１及び膝掛帯部２が相互に摺接しても、（布製のものと比較して）耐久性が良い。さらに、容易に製造することができる。 As described above, the present invention is an integrally molded elastic body made of elastic rubber or elastic elastomer, and the central waist support band 1 and the knee straps connected to the left and right sides of the central waist support band 1 are connected to each other. The central waist support band portion 1 is arranged on the back B side of the user U, and the knee rest band portion 2 is hung on the left and right knees N of the user U to provide an elastic bullet. Since the sitting posture is corrected by the restoring force F, there are no seams or seams, and the durability is good. In particular, in a cross-shaped use state (see FIGS. 3 and 4), even if the central waist support band 1 and the knee rest 2 are in sliding contact with each other, the durability (compared to the cloth one) is durable. Is good. Furthermore, it can be easily manufactured.

また、上記中央腰当て帯部１の中央高さ位置に、該中央腰当て帯部１を上腰当て部１ａと下腰当て部１ｂとに分割形成する、左右方向にスリット状の中央孔部３を有するので、上腰当て部１ａと下腰当て部１ｂとを開いたり重ねたりすることにより、使用者Ｕの腰部に対する圧接部位及び圧接力を、使用者Ｕの好みに応じて変更することができる。
また、上記各膝掛帯部２の中央高さ位置に、該膝掛帯部２を上膝掛部２ａと下膝掛部２ｂとに分割形成する、長手方向にスリット状の側端孔部４を有するので、簡易な構成でありながら、上膝掛部２ａと下膝掛部２ｂとを開いたり重ねたりすることにより、使用者Ｕの膝部の各々に対する圧接部位及び圧接力を、使用者Ｕの好みに応じて容易に変更することができる。 Further, a slit-shaped central hole 3 in the left-right direction is formed by dividing the central lumbar band 1 into an upper lumbar pad 1a and a lower lumbar pad 1b at a central height position of the central lumbar band 1. By opening or overlapping the upper waist pad portion 1a and the lower waist pad portion 1b, the pressure contact portion and the pressure contact force with respect to the waist portion of the user U can be changed according to the preference of the user U. ..
Further, a slit-shaped side end hole portion in the longitudinal direction is formed by dividing the knee-hanging band portion 2 into an upper knee-hanging portion 2a and a lower knee-hanging portion 2b at the center height position of each of the knee-hanging bands 2. Since it has 4, the pressure contact portion and the pressure contact force with respect to each of the knee portions of the user U can be used by opening or overlapping the upper knee hook portion 2a and the lower knee hook portion 2b, although the configuration is simple. It can be easily changed according to the preference of the person U.

また、上記中央腰当て帯部１の肉厚寸法ｔ1 を、５mm以上15mm以下に設定するとともに、上記膝掛帯部２の肉厚寸法ｔ2 を、２mm以上７mm以下に設定し、かつ、上記膝掛帯部２の肉厚寸法ｔ2 を、上記中央腰当て帯部１の肉厚寸法ｔ1 以下に設定し、さらに、上記中央腰当て帯部１の幅寸法ｗ1 を、60mm以上 150mm以下に設定するとともに、上記膝掛帯部２の幅寸法ｗ2 を、40mm以上80mm以下に設定したので、適切な弾発復元力Ｆによって座位姿勢を矯正することができるとともに、容易に使用することができ、かつ、使用感が良い。中央腰当て帯部１が肉厚なので、伸びにくく、腰Ｅに安定して当たるとともに、膝掛帯部２が肉薄なので、伸びやすく、適切な弾発復元力Ｆを生じる。 Further, the wall thickness dimension t 1 of the central waist support band 1 is set to 5 mm or more and 15 mm or less, and the wall thickness dimension t 2 of the knee rest band 2 is set to 2 mm or more and 7 mm or less. the wall thickness t 2 of the knee Kaketai section 2, and set to be equal to or less than the thickness dimension t 1 of the central lumbar support belt portions 1, further, the width w 1 of the central lumbar support belt portions 1, 60mm or more Since the width dimension w 2 of the knee strap portion 2 is set to 40 mm or more and 80 mm or less while setting it to 150 mm or less, the sitting posture can be corrected by an appropriate elastic restoring force F and it is easy to use. And it feels good to use. Since the central hip band portion 1 is thick, it is difficult to stretch and stably hits the waist E, and since the knee rest band portion 2 is thin, it is easy to stretch and an appropriate elastic restoring force F is generated.

また、ＪＩＳ Ｋ７３１２に規定されているＴＹＰＥ Ａ試験器を用いて測定される硬度が、Ａ２〜Ａ１２の弾性体から成るので、身体に密接状となり、使用感が良い。特に、女性や高齢者にとっても、痛みを与えることなく、使用することができる。 Further, since the hardness measured by using the TYPE A tester specified in JIS K7312 is made of an elastic body of A2 to A12, it is in close contact with the body and has a good usability.
