Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a zero-gravity seat frame lifting structure for automotive seats. Background Technology

[0002] Car seat comfort refers to the subjective evaluation of passenger satisfaction from both physiological and psychological perspectives, directly impacting passenger health. Uncomfortable car seats can easily lead to passenger fatigue, and prolonged fatigue increases safety hazards and raises the incidence of traffic accidents.

[0003] In vehicle systems, the seat is the primary interface for human-machine interaction, and its quality directly affects the driving experience of passengers. Comfort is largely a subjective feeling among passengers, and comfort evaluation is subject to uncertainty and ambiguity due to individual differences. Furthermore, because everyone's body structure is different, the level of comfort perceived varies, leading to different impacts of the seat on human comfort. Utility Model Content
