摘要： A child safety seat includes a seat shell for receiving a child, an extension member, an extension locking mechanism operable to lock the extension member with respect to the seat shell, and an anti-rebound part. The anti-rebound part can be installed on the extension member or the seat shell. The child safety seat is installable on a vehicle seat in a rear facing position with the anti-rebound part extending at an angle above the extension member and adjacent to a seatback of the vehicle seat.

摘要： A foldable car seat carriage includes a frame unit and an engagement unit. The frame unit includes two leg frames. Each of the leg frames includes two legs pivotable relative to each other, and a driving mechanism. The driving mechanism has opposite ends connected pivotally to the legs at first and second intersections. The engagement unit includes two bayonets. Each of the bayonets has a linking portion connected pivotally to the driving mechanism of a respective one of the leg frames. For each of the leg frames, change of a distance between the first and second intersections of the driving mechanism and the legs during pivot action of the legs converts a position of the engagement unit relative to the legs.

摘要： A child restraint system is provided and configured to be installed on a vehicle seat to support a child. The child restraint system includes a main body, a reclining foot and an adjusting foot. The main body includes a seat portion and a backrest portion. The reclining foot is pivotably coupled to the main body. The adjusting foot is pivotably coupled to the main body or the reclining foot. The adjusting foot is pivotable between a forward position and a rearward position. No matter when the child restraint system is in a rearward-facing direction or a forward-facing direction, the child restraint system can be supported stably on the vehicle seat, and a recline position of the child restraint system can be adjusted in a wide adjustment range by pivoting of the reclining foot. Therefore, the child restraint system is convenient to use.
