Abstract: The car seat frame and functional components are important carriers for supporting the sitting posture of drivers and passengers, and their appearance and layout parameters greatly affect the safety, operation, and comfort of drivers and passengers. The layout of the seat frame and functional components is the focus of seat engineering design and the foundation of styling design. Based on ergonomics and relevant laws and regulations, this paper analyzes the design principles and reference basis of the fore and aft adjustment, height adjustment, backrest rotation adjustment, lumbar four-way adjustment, and head restraint up and down adjustment of the electric seat, which can confirm the engineering hard points of the seat cushion, backrest, and head restraint position track in the modeling design stage, ensure that the modeling design conforms to safety, operability, and comfort, and improve the overall design quality of the electric seat, povide theoretical support for the seat frame module in the interior design of the entire vehicle, and improve the efficiency of the grouping design of the automotive interior.
