On April 16, the return capsule of the Shenzhou 13 manned spacecraft successfully landed at the Dongfeng Landing Site. Astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu exited the capsule safely and smoothly, and “sit down” on their chairs to receive blessings and interviews. The reporter learned that this special “escort chair” was independently developed by Sitting Technology Co., Ltd. in Nantou Town, Zhongshan City. to help them re-adapt to gravity.

Why do astronauts sit in the “escort chair” after leaving the cabin?
When Shenzhou 13 returned to the live broadcast, the astronauts generally sat on chairs and were carried away by the staff. According to professionals, this is because astronauts stay in a weightless environment in space for a long time, which will lead to serious problems such as muscle atrophy due to the lack of muscle strength.
In order to alleviate such situations, in the space station, astronauts will do a lot of exercise, and even professional sports team protection experts will formulate professional training tasks for them. But when they landed on the ground, the astronaut’s muscles still couldn’t adapt to the situation of exerting force, so they couldn’t stand up and walk at all.
As my country’s longest resident astronauts in space, the three astronauts on the Shenzhou 13 spacecraft are also the most affected by the gravity-free environment of space in my country. After they landed, there were rescuers and flight crews immediately Surgeons accompany them to help them re-adapt to gravity. The “escort chair” is also a part of the landing rescue, which supports the astronauts in various states such as rest, movement, and communication.
“Effective low-gravity full-body support to assist astronauts in re-adapting to gravity is the first focus of our research and development.” According to Chen Min, founder and general manager of ZhanSense Technology Co., Ltd., during the research and development process, the company learned from the astronauts’ From the mobile safety straps, to the head support state of astronauts wearing different space suits, and various effective support methods from head to toe when sitting and lying down, all need to be designed and verified one by one .
Although the design concept of the zero-gravity office chair (providing effective support for the whole body to achieve a static support mode of the human body that reduces the influence of gravity) is exactly in line with the low-gravity mode required by the astronauts after their return, but the redesign is designed for the Shenzhou 13 spacecraft. They also spent nearly half a year on the “escort chair” that the astronauts sat on.
“As the astronauts landed and returned to the base, they had to travel to many places and use a variety of traffic conditions, so in addition to the design, we should also consider lightness and carryability, as well as convenience and adaptability to various state changes of the astronauts, and ensure that It can be placed and moved as a whole.” Chen Min introduced that the landing environment is the wasteland and the Gobi, this time using “zero gravity” and “escort chair”, it is necessary to transform the chair that was only used indoors in extreme environments, such as using suitable Extremely low temperature materials ensure smooth operation in windy and dusty weather conditions.
What are the characteristics of the “escort chair”?
Safety, comfort and adaptability are the biggest features of this “escort chair” made by Zhongshan. The “escort chair” is not only based on ergonomic structure design, the state setting and switching process have won the approval of the medical and nursing team for the safety and comfort of this product; in the process of sample trial, the comfort level has also been obtained It is affirmed by the experiencers of the acceptance team; in addition, the product has a wider range of adaptability, which not only adapts to the user’s sitting, leaning, etc., but also adapts to outdoor sandstorms and cold weather, and can also be adapted to carry, park, etc. on rough roads.
“The change in lifestyle has changed the direction of research and development of seats (static support equipment for the human body).” Zhao Yuya, deputy general manager of Sitting Technology Co., Ltd., also said that in addition to the research and development of the “escort chair” of the Shenzhou 13 spacecraft, The company is also actively exploring various products that are more suitable for consumers.
