A baby carriage includes a handle, a first fixing member, a second fixing member, a rear leg, a front leg, an unlock member, a first lock member, a rotating member and a pulling member. The first lock member engages with the first fixing member and the second fixing member to lock the handle, the rear leg and the front leg at a first unfolded position. When the unlock member pulls the pulling member, the pulling member drives the rotating member to rotate, a first inclined driving surface of the first fixing member pushes the rotating member toward the first lock member, and the rotating member pushes the first lock member toward the second fixing member to disengage the first lock member from the first fixing member.

A foldable stroller for transporting up to two child passengers in a tandem arrangement includes seating configurations that may be easily altered dependent upon the age/size of the passengers. The stroller frame includes an upper seat connector for selectively attaching an upper seat. A lower seat connector is positioned forward of and below the upper seat connector and includes a linkage that allows movement of an associated lower seat between opposing forward and rearward positions without altering the inclination of the lower seat. The forward connector position locates the associated lower seat sufficiently forward to provide clearance for the upper seat and its occupant. When the upper seat is removed, the linkage enables the associated seat to be shifted to the rearward position, shifting the center of gravity location rearward for improved stroller stability.

A child carrier is provided and includes a frame, a seat and a folding device installed between the frame and the seat. The frame includes a handle, a front leg pivotally connected to the handle and a rear leg pivoted to the handle. The folding device includes a sliding structure and a linking component. The sliding structure is fixedly disposed on the handle. The seat is slidably coupled to the sliding structure. The linking component includes a first end and a second end. The first end is pivotally coupled to the seat. The second end is pivotally connected to the rear leg. The linking component is driven to drive the seat to slide along the handle when the handle pivots relative to the rear leg.

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.

A baby wagon with improved ease of use has a folding structure which is stably configured, and thus damages to frames, such as twisting or bending of the frames, can be prevented, such that the baby wagon is stably folded and unfolded, the use of the baby wagon is convenient while durability of the baby wagon is excellent, and comfort of a baby can be maintained even when the baby is in the baby wagon for a long time. The frames are manufactured so as to be easily folded even in the state in which the canopy is coupled thereto, whereby the baby wagon is unfolded and folded within a short time, such that that portability and mobility of the baby wagon are excellent, and such that detachment and coupling of a canopy and a wheel assembly are easily performed.

A sliding sleeve is fixedly provided on a front wheel support, such that a rear wheel support is rotationally connected to the front wheel support; a lower push rod is slidably arranged in the sliding sleeve; a basket rod and is rotationally connected to the lower push rod and is rotationally connected to the rear wheel support; a seat rod extends downwards and is rotationally connected to the lower push rod; and a supporting rod is connected to the front portion of the seat rod and is rotationally connected to the front wheel support, such that when a locking mechanism is unlocked, the lower push rod slides downwards relative to the sliding sleeve to drive the rear wheel support, the seat rod, the supporting rod and the basket rod to be folded to the front wheel support, and automatic folding of the stroller is completed.

A foldable backrest structure (50) adapted for a frame (40) of a child carrier (100), includes a backrest (30), a releasing mechanism (20) and a trigger (10). The backrest (30) is pivoted to the frame (40). The releasing mechanism (20) is disposed between the backrest (30) and the frame (40). The releasing mechanism (20) includes a first abutting component (22). The trigger (10) is disposed on the frame (40) and for slidably abutting against the first abutting component (22) to drive the releasing mechanism (20) to release the backrest (30), so as to allow the backrest (30) to be folded together with the frame (40) when the frame (40) is being folded. The foldable backrest structure (50) of the present invention has advantages of simple structure, easy operation and low manufacturing cost. Besides, the present invention further discloses a child carrier (100) including the aforementioned foldable backrest structure (50).
