A backrest angle adjusting mechanism, suitable for being assembled between a seat body and a backrest of an infant carrier, having the seat body being installed on a frame, the backrest being rotatably connected to the seat body, and wherein the backrest angle adjusting mechanism includes a fixing member and an adjusting member. The fixing member is fixed on the backrest, one end is connected to the seat body or frame to form a connecting part, and the other end is bypassed around the fixing member to form an operating part. Operating the operating part causes the adjusting member to slide on the fixing member, and sliding the adjusting member brings the backrest to rotate with respect to the seat body, thereby adjusting an inclination angle of the backrest.

Foldable strollers with removable seats and related methods are disclosed herein. An example stroller disclosed herein a wheeled frame, a receiver coupled to the frame, and a seat. The seat includes a mount, a lock disposed in the mount; and a handle having an extended positon and a retracted position relative to the seat. The lock is to move from a first position to a second position when the mount is disposed in the receiver to removably couple the seat to the frame, and the lock to move from the second position to the first position to release the seat from the receiver when the handle moves from the retracted position to the extended position.

A backrest angle adjusting mechanism and an infant carrier having the same. The backrest angle adjusting mechanism is assembled between a seat body and a backrest of the infant carrier, the seat body being installed on a frame, the backrest being rotatably connected to the seat body, wherein the backrest angle adjusting mechanism comprises a fixing member, an adjustment member, and a connecting member, one end of the connecting member is connected to the backrest, the other end of the connecting member is connected to the fixing member, one end of the adjustment member is connected to the seat body or the frame to form a connecting part, and the other end of the adjustment member is bypassed around the fixing member to form an operating part, operating of the operating part causes the adjustment member to slide on the fixing member to rotate in respect to the seat body.

A folding wagon with a footwell for carrying small children or other articles. The folding wagon has a solid frame with scissor connections, that allow it to be compacted for storage and expanded for use. The footwell allows children a place to rest their feet within the wagon. The folding wagon has a fabric paneling system, from which portions can be removed for the cleaning of the wagon and the footwell. The folding wagon also has two canopies, allowing the carrying of two children with the canopies protecting them from the sun or the elements. The folding wagon can use attachments that expand its capabilities.

A seat height adjustment mechanism includes a locking bar and a locking element. The locking bar is disposed in a stroller frame and has locking holes spaced apart. Each of the locking holes has a stop portion protruding therein. The locking element is mounted on a seat and has an engaging end. The engaging end is separably engaged in any one of the locking holes and has an engaging hook protruding in a direction, and the direction is crossed with another direction in which the engaging end moves when the engaging end is separating from the locking hole. The engaging hook separably presses against the stop portion. Therefore, the engaging end cannot separate from the locking hole. Even when wrongly operated, the locking element cannot be rotated and unlocked and thereby prevents the seat from unnecessarily sliding downward, so as to ensure safety of a baby at the seat.

A seat includes a support base, an unlock member and a lock member. The support base has at least one through hole. The unlock member is movably disposed on the support base and has at least one first driving portion. The lock member is movably disposed on the unlock member. The lock member has at least one lock portion protruding from a surface of the support base through the at least one through hole and at least one second driving portion abutting against the at least one first driving portion. When the unlock member is forced in a first direction to move, the at least one lock portion is forced to move along the at least one first driving portion through the at least one second driving portion and retracts into the support base in a second direction different from the first direction.

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).

A backrest angle adjusting mechanism and an infant carrier having the same. The backrest angle adjusting mechanism is assembled between a seat body and a backrest of the infant carrier, the seat body being installed on a frame, the backrest being rotatably connected to the seat body, wherein the backrest angle adjusting mechanism comprises a fixing member, an adjustment member, and a connecting member, one end of the connecting member is connected to the backrest, the other end of the connecting member is connected to the fixing member, one end of the adjustment member is connected to the seat body or the frame to form a connecting part, and the other end of the adjustment member is bypassed around the fixing member to form an operating part, operating of the operating part causes the adjustment member to slide on the fixing member to rotate in respect to the seat body.

A pram may be used to transport babies and relatively young infants, and may provide a relatively horizontal surface for the baby or infant to be transported upon in a flat lying position. A pram may also be used to transport relatively older infants, and may provide a seat arrangement for the infant to be transported in a sitting position. However, babies and infants grow quickly and may outgrow conventional prams within a year or two years. Therefore, a parent or guardian must typically provide several prams for their child. Furthermore, a pram offering optimal comfort or safety may not be convenient when travelling or for city living. An aspect of the present disclosure includes a child transportation system comprising a frame 100, wherein the frame 100 is width adjustable between a relatively narrow compact arrangement and a relatively wide comfort arrangement. The frame 100 also includes an infant carrier attachment mechanism 500 configured and arranged to permit, in use, a seat 200 or an infant carrier module 300 to be releasably attached to the frame 100.

There is provided an adjustable infant carrier comprising: a backrest for supporting the upper body of an infant, the backrest having a front side and a rear side; a support shaft arranged at the rear side of the backrest; a harness assembly comprising at least one plate member arranged on the front side of the backrest; and a releasable locking mechanism positioned between the at least one plate member and the support shaft, the releasable locking mechanism being connected to the at least one plate member and being configured to secure the position of the harness assembly relative to the support shaft and relative to the backrest; and wherein the at least one plate member and releasable locking mechanism are jointly slidably moveable relative to the support shaft and relative to the backrest.
