A backrest adjusting mechanism disposed between a backrest tube and a frame of an infant carrier includes an outer cover fixed at the frame, an inner cover connected to the backrest tube and pivoted to the outer cover, a driving member movably disposed between the outer and inner covers, a locking member movably disposed on the driving member, and an operating member connected to the driving member for driving the driving member between first and second positions. Switching of the driving member between the first position and the second position drives the locking member to selectively lock or release the outer cover and the inner cover. Two first locking portions are disposed on the outer cover, a second locking portion is disposed on the inner cover, and the locking member is cooperated with the second locking portion and selectively cooperated with one of the two first locking portions.

A multi child stroller includes a stroller frame and a first seat. The stroller frame has two sections adapted to fold and unfold relative to each other. The first seat is disposed on one of the two sections. The first seat includes a first seat unit and a seat back positioning member. The first seat unit has a sliding slot portion. The seat back positioning member is rotatably disposed on the stroller frame.

A child stroller includes a stroller frame and a first seat. The stroller frame has two sections capable of being folded and unfolded relative to each other. The first seat is disposed on one of the two sections in a detachable manner. The first seat includes a supporting unit and a first seat frame. The first seat frame is adapted to hold the supporting unit. The first seat frame includes a seat hub, an upper seat tube and a lower seat tube. The seat hub is disposed on the stroller frame. The upper seat tube is disposed on the seat hub, and the supporting unit is slidably disposed on the upper seat tube. The lower seat tube is disposed on the seat hub and detachably connected to the supporting unit.

A headrest support structure applied to a safety seat is disclosed. The headrest support structure includes a buffer mechanism. The buffer mechanism is connected to a headrest and a seat of the safety seat. Elastic deformation of the buffer mechanism provides a buffer to the headrest and the seat. The headrest support mechanism provided by an embodiment of the present application has a high safety factor and provides a buffer to the headrest and the seat during an emergency brake for accident prevention. The present application further provides an infant carrier having the headrest support structure.

This description is related to an adapter that can be coupled to a stroller frame (e.g., to one side of the stroller frame) or other child product and that is changeable between a first configuration for supporting a first type of accessory (e.g., stroller accessory) and a second configuration for supporting a second type of accessory. The adapter can include a hub that is rotatable relative to the stroller frame or child product and can include a first connector and a second connector positioned at different locations relative to the hub. In examples, when the hub is rotated to a first position, the first connector can be in position to support the first type of accessory, and when the hub is rotated to the second position, the second connector can be in position to support the second type of accessory.

A child seat transporting system comprising a base being detachably connectable to a vehicle seat, a safety part being detachably connectable to the base and a child seat being detachably connectable to the safety part. The child seat comprises at least one child seat handle to carry the child seat when disconnected from the safety part. The safety part, when disconnected from the base, is detachably connectable to a frame of a stroller, whereby when the safety part with the child seat connected thereto is connected to the frame of the stroller, the child seat is detachable from the safety part.

An infant car seat includes a seat base and a stability leg. The stability leg is rotatably disposed under the seat base. The stability leg includes an upper leg tube, a rotary member and a first latch. The upper leg tube includes at least one opening. The rotary member includes a pivoting portion and an encircling portion. The pivoting portion is rotatably connected to the seat base. The encircling portion is connected to the pivoting portion and slidably disposed on the upper leg tube. The first latch is disposed on the rotary member, and adapted to detachably engage with the at least one opening for constraining a movement between the rotary member and the upper leg tube.

A holder includes a vertical holding part configured to support an infant in a vertical posture so that the head is positioned vertically, in which the vertical holding part has a front pad part extending in a vertical direction and configured to support the infant from a front of the infant, at least from the abdomen to the chest of the infant.
