Seat belt interface mode is actually the interface mode of the car itself, which has good compatibility and can be used with different models of children's seats or different standard models of children's seats. In China, most cars use seat belts, which is simple and convenient to use.
Seat belt fixation is the most widely used method for children's seats at present, which can support both forward fixation (children's seats facing the front seats) and reverse fixation (children's seats facing the rear seats).
