The recline seatback is adapted to pivot about a hinge, and has a seatback lock assembly to fix the seatback in a plurality of angled positions.

A child stroller apparatus includes a stroller frame and a stroller seat. The stroller seat includes a backrest portion fixedly connected with a first joining part, a seat portion fixedly connected with a second joining part that is pivotally connected with the first joining part, a coupling part pivotally connected with the second joining part at a side thereof opposite to that of the first joining part and adapted to connect with the stroller frame, a latch movable between a locking position engaged with the coupling part and an unlocking position disengaged from the coupling part, and a linking mechanism configured to movably couple the latch to the first joining part so that the backrest portion is rotatable in a folding direction to cause the latch to disengage from the coupling part and in an unfolding direction to cause the latch to engage with the coupling part.

A winch reel system is provided for use in child containment devices. The winch reel systems can include a one-way winch reel, a two-way winch reel, a multi-cord winch reel, and/or a drawstring winch reel. The winch reel systems can be included in various child containment devices, including strollers, infant rockers, children's car seats, playards, infant swings, baby carriers, bouncers, jumpers, high chairs, play mats, baby gates, children's booster seats, and/or other types of infant carrier or containment systems and devices. Each winch reel system can include one or more wires that are engaged with a winch reel in order to adjust at least one feature of a child containment device. In other embodiments, the one or more wires can be replaced with one or more lines, cables, or straps. In some embodiments, each winch reel system can include at least one toothed pawl to engage the winch reel.

A passenger transport carrier includes a lower frame having a first end and a second end, and an upper frame having a first channel defined therein, a first end, and a second end. The carrier also includes a rear frame extending from the second end of the lower frame to the second end of the upper frame. The carrier further includes a first upper seat support including a cross-member extending transversely across the carrier and having a first end and a second end, and a first elongate member extending from the first end of the cross-member of the first upper seat support and slidably received within the first channel of the upper frame. The first upper seat support is configured to move between a first seat position and a second seat position.

A child stroller apparatus includes a stroller frame, a connecting mount provided on the stroller frame and having a first coupling portion, and an adapter suitable to receive the installation of a detachable component. The adapter is installable on and detachable from the first coupling portion of the connecting mount, and includes a support body having a second and a third coupling portion, the second coupling portion being connectible with the first coupling portion, and the third coupling portion being connectible with a detachable component. The first coupling portion of the connecting mount is adapted to receive the installation of the adapter and a detachable component, and the arrangement of the adapter on the connecting mount allows the installation of a detachable component on the third coupling portion of the adapter at a mount position that differs from a mount position provided by the connecting mount.

A transportation device includes a frame and a carrier. The frame includes a rail, a fixing base, an unlock member and a sliding member. The rail has a first engaging hole with a first retaining wall. The unlock member has an engaging portion. An end of the sliding member abuts against the unlock member. The carrier includes a connecting base with a rib. The connecting base is connected to the fixing base to install the carrier on the frame. When the carrier faces a first direction, the rib pushes the sliding member to push the unlock member, such that a length of the engaging portion protruding from the fixing base is reduced. When the carrier faces a second direction, the rib is staggered with the sliding member.

A foldable backrest returning mechanism including a backrest plate and an elastic returning device is disclosed. The backrest plate has a foldable portion. The foldable portion divides the backrest plate at least into a first plate and a second plate. The first plate and the second plate are foldable relative to the foldable portion. The elastic returning device is assembled between the first plate and the second plate, the elastic returning device provides an elastic force to drive the first plate and the second plate to approach each other relative to the foldable portion for making front surfaces of the first plate and the second plate have a returning tendency to approach toward each other. Accordingly, the present invention can prevent arching of the backrest plate at the foldable portion. Furthermore, the present invention provides an infant carrier.

A collapsible seat assembly is mounted on a frame of a stroller, and includes a joint member, a backrest support member, a leg support member and a locking mechanism. Each of a pivot portion of the backrest support member and a pivot portion of the leg support member is pivotably mounted on the joint member. The locking mechanism is disposed between the pivot portions to lock or unlock the backrest and leg support members. The locking mechanism is configured to be actuated to move from a locking position to an unlocking position by the operation of the frame of the stroller from an unfolded state to a folded state. A stroller having the collapsible seat assembly is also disclosed.
