A child carrier includes a supporting frame, a sliding base, a seat, an insert member disposed on the seat for selectively engaging with or disengaging from the sliding base, and an actuator operable to drive the insert member to be engaged with or be disengaged from the sliding base. The sliding base is disposed on the supporting frame and slidable in a substantially longitudinal direction of the supporting frame. The seat is foldably assembled with the sliding base and includes a seat portion selectively coupled to the sliding base. The seat portion includes an engaging member having an engaging portion, and the engaging portion is operable to engage with the sliding base. The actuator is able to drive the insert member to move a first distance. The supporting frame is driven to be folded up when the sliding base slides upward along the supporting frame.

A booster seat (1) for children comprising a frame (2) composed of a front structure (3) and a rear structure (4), the front structure (3) comprising a lower base portion (5) and an upper backrest portion (6), the rear structure (4) being rotatably attached to the lower base portion (5); a seat portion (8) rotatably attached to the upper backrest portion (6); a tray (9) comprising a pair of lateral arms (11); the tray (9) being rotatably attached to the upper backrest portion (6) for the tray (9) to be commuted between a use configuration in which the tray (9) overhangs the upper backrest portion (6) and a stored configuration in which the tray (9) is substantially parallel to the upper backrest portion (6); the booster seat (1) being adapted to be commuted between an open configuration and a closed configuration whereby, in the open configuration, the lower ends of the lower base portion (5) and the lower ends of the rear structure (4) are spaced apart from each other, with the seat portion (8) substantially parallel to the tray (9) which is in the use configuration, and in the closed configuration, the lower ends of the lower base portion (5) are close to the lower ends of the rear structure (4) with the seat portion (8) and the tray (9) substantially parallel to the upper backrest portion (6).

A child seat includes a seat portion fixedly connected with a first coupling part, a connector pivotally connected with the first coupling part of the seat portion, the connector being operable to detachably engage with a corresponding structure provided on a child supporting apparatus, a locking mechanism operable to lock and unlock the connector with respect to the seat portion, a backrest frame fixedly connected with a second coupling part that is pivotally connected with the first coupling part, and a coupling mechanism operable to movably couple the seat portion to the backrest frame so that the seat portion and the backrest frame are movable in unison relative to the connector during adjustment of the backrest frame between an unfolded state and a folded state.

A foldable mechanism is applied to locking an infant carrier and includes first and second mounts and a locking member. The second mount is pivoted to the first mount and has first and second mating portions. The infant carrier is locked in the folded state when the first mount rotates to a first rotating position, and is locked in the expanded state when the first mount rotates to a second rotating position. The locking member is movably disposed between the first and second mounts and has a positioning portion and a locking portion. The positioning portion is engaged with the first mating portion to lock the first mount at the first rotating position. The locking portion is engaged with the second mating portion to lock the first mount at the second rotating position. A depth of the first mating portion is shallower than a depth of the second mating portion.

A sit-to-stand convertible highchair includes a frame configured to support the sit-to-stand convertible highchair above a floor, a foot platform adjustably mounted on the frame, and a seat assembly adjustably mounted on the frame above the foot platform. The seat assembly includes a backrest and a support surface configured to convert between a sitting configuration, in which a user may sit on the support surface, and a standing configuration, in which the user may extend through the support surface to stand on the foot platform.

A child seat includes a seat portion fixedly connected with a first coupling part, a backrest frame fixedly connected with a second coupling part, the second coupling part being pivotally connected with the first coupling part so that the backrest frame is rotatable relative to the seat portion, a rotary element pivotally connected with the first coupling part, the rotary element being rotatable relative to the seat portion and the backrest frame, and a locking mechanism operatively connected with the backrest frame and operable to rotationally lock and unlock the rotary element with respect to the seat portion. The locking mechanism is configured to switch between a locking state and an unlocking state in response to a rotation of the backrest frame relative to the seat portion and the rotary element.

An infant highchair includes a standing frame including a support platform, a seat pivotally connected with the standing frame and having a seating surface, and a locking mechanism operable to lock the seat in position. The seat is rotatable between a first and a second position, the first position allowing a child to sit in contact with the seating surface, and the second position being suitable to receive installation of a removable child seat over the seat while disabling seating of a child on the seating surface, the seating surface moving around the support platform when the seat rotates relative to the standing frame, the second position of the seat uncovering the support platform so that a removable child seat is installable over the seat at least partially supported in contact with the support platform. The locking mechanism is operable to lock the seat in the first and second position.
