Embodiment 1

[0067] Such as Figure 6a , 6b , 6c shows the front, back and side views of the garment of Example 1, using polyester-cotton blended yarn to weave double rib weave to form a non-elastic fabric 7 to form the first gripping area 1 of the garment. Nylon ammonia core-spun yarn is used to weave the composite weft-knitted fabric. The transverse density of the fabric increases gradually from top to bottom, and the vertical density of the fabric increases with the increase of the circumference of the human body, forming a gradient elastic fabric 8. The control strips 9 are spaced at intervals of 10cm. The warp weaving is woven into the composite weft knitting to jointly form the variable elastic fabric 10 to form the initial gravity loading area 2 of the garment. The first holding area 1 and the initial gravity loading area 2 are woven by integral molding on a knitting machine. The hook-like fabric 11 is selected as the connection device I, and the fluffy fabric 12 is used as the co...

Embodiment 2

[0070] Such as Figure 7a , 7b , 7c shows the front, back and side views of the garment of Example 2, using polyester-cotton blended yarn to weave double rib weave to form a non-elastic fabric 7 to form the first gripping area 1 of the garment. Nylon ammonia core-spun yarn is used to weave the composite weft-knitted fabric. The transverse density of the fabric increases gradually from top to bottom, and the vertical density of the fabric increases with the increase of the circumference of the human body, forming a gradient elastic fabric 8. The control strips 9 are spaced at intervals of 10cm. The warp weaving is woven into the composite weft knitting to jointly form the variable elastic fabric 10 to form the initial gravity loading area 2 of the garment. The first holding area 1 and the initial gravity loading area 2 are woven by integral molding on a knitting machine. The metal wire 13 is selected as the connection device I, and the metal hook 14 is used as the connection ...

Embodiment 3

[0073] Such as Figure 8a , 8b , 8c shows the front, back and side views of the garment of Embodiment 3. This example shows the simplified structure of the knitted-based gravity-loaded garment after it has been stretched. It is divided into the first grip area 1, The gravity loading area 15 and the second gripping area 4 use the same fabric structure as above, that is, the non-elastic fabric 7 , the gradient elastic fabric 8 , the control strip 9 and the shape memory fabric 5 . Preferably, the shape memory fabric 5 can be sewn on both sides of the garment to better control the gradient elastic fabric 8 and help control the strip 9 to maintain the stability of the garment.

Abstract

The invention relates to an adjustable gravity loading garment for simulating the physiological load of a spine, which is designed for the spine by combining a non-elastic fabric and a variable-elasticity fabric, and compared with the existing elastic material for loading the gravity, the adjustable gravity loading garment can better simulate the physiological load of the spine of a human body. By means of the calculus fabric structure, gravity loading is continuously increased from the neck root line to the thigh girth line, effective confrontation is generated on human body structures such as vertebras, intervertebral discs, paravertebral muscles and intervertebral ligaments, and non-specific lumbago of astronauts or space travelers is avoided. Besides, all-directional pressure loading of the fabric on the human body is fully considered, an axial loading and radial fixing structure is adopted, good wearing comfort in the axial direction and the radial direction is guaranteed, discomfort of other parts of the human body is prevented, and other diseases are avoided. By combining the movable connecting device and the shape memory fabric, high wearing and taking-off performance is guaranteed, wearing and taking-off can be completed by a single person, and meanwhile the gravity loading requirements of different space environments are met.

Description

technical field [0001] The invention relates to a spacesuit design technology, in particular to an adjustable gravity-loaded garment that simulates the physiological load of the spine. Background technique [0002] The microgravity environment in space will have a significant impact on the physiological system of astronauts, especially the damage to the motor system that cannot be ignored. Microgravity weakens the support and protection function of the human body movement system by inducing the atrophy of the human body's anti-gravity muscles, the loss of load-bearing bones, and the expansion of interosseous soft tissues, thereby causing discomfort and even diseases, thus seriously threatening the health of astronauts. As an important load-bearing organ in the sports system, the spine will undergo physiological changes such as paravertebral muscle atrophy, vertebral density decrease, and intervertebral disc expansion in a microgravity environment, resulting in abnormal spine...
