[0001] The utility model belongs to the technical field of aerospace metrology, and in particular relates to a human body posture fixing device for a space station. Background Art

[0002] Body mass is one of the most basic physiological indicators of the human body. Stable body mass is a basic sign of good health. Changes in body mass reflect the state of human metabolism. In space, the measurement of body mass is critical for monitoring the health and physiological changes of astronauts, especially in long-term missions. Regular monitoring of body mass can not only help adjust astronauts' diet, exercise plans and workload, but also predict space diseases and design safety protection.

[0003] There are many methods for measuring human mass on the ground, but they are generally not suitable for space applications. Measuring mass in orbit requires overcoming difficulties such as the microgravity environment, human flexibility, and the difficulty in determining the center of mass of the human body during measurement. Therefore, a special space weighing scale, i.e., a mass meter, is needed.

[0004] The human body holder is mainly used as a device for controlling the human body posture when measuring human mass in the space microgravity environment. It is required to be light in weight, easy to store, and able to better constrain the human body posture. However, due to insufficient constraints on the degrees of freedom and insufficient rigidity caused by internal gaps in the structure, it causes shaking during mass measurement, which will lead to insufficient measurement stability and precision, and inaccurate results.
