Abstract

An article of clothing has a main body formed of high-tightness, main-body knitting fabric made of power net. The article of clothing includes front and back support pieces disposed around the waist and having no elasticity in a longitudinal direction thereof. The front support pieces are sewn to a front body at positions inside the left and right ilia of the abdominal pelvis. The back support pieces are sewn to a back body at left and right positions near the sacrum of the pelvis in central hip portions. Side waist pieces disposed between the front and back support pieces are formed by sewing high-tightness, net-like knitting fabric to the main-body knitting fabric at the top edge while leaving the bottom edge unsewn. The article of clothing has a pant-like shape with left and right leg parts that can be tightly fitted around the thighs.

Claims

1. An article of clothing for the lower half of the human body, the article of clothing having a function of body shape correction and including a main body formed of main-body knitting fabric, the main-body knitting fabric providing a high degree of tightness and being made of power net, the article of clothing comprising:

front support pieces formed of interlining having no elasticity in a longitudinal direction thereof, the front support pieces being sewn to a front body of the article of clothing at positions inside the ilia on the left and right of the abdominal pelvis of the wearer;

back support pieces formed of interlining having no elasticity in a longitudinal direction thereof, the back support pieces being sewn to a back body of the article of clothing at left and right positions that are closer to the back support piece than the gluteus medius muscles of a wearer;

waist pieces extending rearward from side portions between the front support pieces and the respective back support pieces to regions around the gluteus medius muscles, the waist pieces having a three-layer structure including the main-body knitting fabric and net-like knitting fabric folded at a bottom edge to form a two-layer structure and placed on the main-body knitting fabric, the net-like knitting fabric providing a high degree of tightness;

a navel cover piece provided in the front body and having a three-layer structure in which the main-body knitting fabric is folded so as to sandwich the net-like knitting fabric; and

an abdomen piece disposed below the navel cover piece and having a two layer structure including the main-body knitting fabric facing outside and the net-like knitting fabric facing inside,

wherein the waist pieces having the three-layer structure and the navel cover piece having the three-layer structure are configured to increase an abdominal pressure for preventing or relieving back pain,

wherein, in the waist pieces having the three-layer structure, the main-body knitting fabric and the net-like knitting fabric folded to form the two-layer structure are sewn together at a top edge thereof, and the folded bottom edge of the net-like knitting fabric forming the two-layer structure is not sewn to the main-body knitting fabric and is free from the main-body knitting fabric in areas other than a central area of the back body, thereby providing a function of pulling both sides of the pelvis rearward to facilitate a forward movement of the sacrum and reduce lordosis of the lumbar spine, and

wherein the article of clothing has a pant-like shape with left and right leg parts that can be tightly fitted around the thighs.

2. The article of clothing according to claim 1, further comprising:

a piece disposed below the waist in the back body and formed only of the main-body knitting fabric; and

a waist piece disposed between the back support pieces in a central area of the back body and formed of the net-like knitting fabric folded to form a two-layer structure, thereby providing a tight-fit feeling,

wherein the waist pieces between the front support pieces disposed at positions near the pelvis in the front body and the respective back support pieces are tightly restrained such that the knitting fabric of the waist pieces is pulled toward the back support pieces.

3. The article of clothing according to claim 1 or 2, wherein back thigh pieces of the article of clothing having the pant-like shape have a two-layer structure including the main-body knitting fabric and the net-like knitting fabric, so that tensile load is applied thereto when the thighs are lifted during walking.

4. The article of clothing according to claim 2, wherein the main-body knitting fabric and the net-like knitting fabric have a tensile strength of 490 mN or more when stretched by 30%.
