[0002] Existing infant and toddler vehicles, such as infant safety carriers, child safety seats, and baby seats, while meeting the needs of carrying and protecting infants and toddlers to a certain extent, still have some problems in actual use.
[0003] First, the adjustment methods of traditional infant and toddler vehicles are rather cumbersome. They usually change the tilt angle of the backrest by adjusting the straps. This method is not only inconvenient to operate, but also has limited adjustment precision, making it difficult to meet the diverse needs of parents and infants and toddlers.
[0004] Secondly, because infant carriers lack flexible adjustment mechanisms, they cannot be personalized according to the infant's body shape and growth needs, which affects the infant's comfort and user experience.
[0005] In addition, some traditional infant carriers require the seat to slide forward relative to the base to extend when adjusting the angle between the backrest and the seat. This design requires that protective materials (such as padding, covers, etc.) have sufficient space to allow the seat to slide and extend properly, resulting in increased costs and inconvenience.
[0006] Therefore, this utility model was developed to address the aforementioned problems. [Utility Model Content]
