[0002] With the rapid development of society, people's pace of life has become faster, and the time for rest in life is not only getting less and less, but also more fragmented. Facing the people with healthy limbs, the middle-aged and elderly groups have poorer physical strength than young people, and cannot stand or walk for a long time, and need to rest more frequently when traveling. Young and middle-aged groups generally have learning and work tasks, and need to spend as little as half an hour and as long as two hours on the road every day. If this time can be used more for rest, it can also better improve the efficiency of learning and work. However, in actual situations, there may not be a place to rest when waiting for public transportation and using public transportation when commuting to get off work (school). Therefore, how to rest and restore physical strength anytime and anywhere when traveling and make good use of fragmented time has become a problem facing the whole society now, and has become a social problem that people pay close attention to, and emergency wearable anti-slip seats came into being in such an environment.
