[0002] With the rapid development of the automobile industry, consumers have higher requirements for the comfort of automobile seats. Automobile seats are not only the basic facilities for drivers and passengers to sit on, but also important factors that affect driving safety and riding experience. In order to meet market demand, automobile manufacturers and seat suppliers continuously improve the design of seats to make them more in line with the principles of ergonomics and improve the comfort of sitting. However, how to effectively evaluate and verify the comfort of seats has become a problem to be solved.
