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 locking member is movably disposed between the first and second mounts and is movable along an axial direction of a rotating axis of the first and second mounts to lock and release rotation of the first mount. The locking member has a positioning portion and a locking portion. The first mount is locked at a first rotating position or a second rotating position via movement of the locking member. 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 seat lifting apparatus includes a lifting platform attached to a seat. The lifting platform includes an unlocking element, a resilient element, and a positioning part. The positioning part comprises first and second contact surfaces and can move between first and second positions. The resilient element contacts the first contact surface and applies a force towards the second position. The unlocking element contacts the second contact surface and applies a force towards the first position. The base is disposed on a frame and includes a chamber. The lifting platform moves up and down within the chamber. The chamber includes limiting parts in the vertical direction. When the positioning part is in the second position, it matches with the limiting part to lock the seat height, and when the positioning part is in the first position, it separates from the limiting part to adjust the seat height.

A seat assembly comprises a booster seat with a lower support surface and an upper seating surface. A back support extends upwardly at the rear of the upper seating surface and side supports extend from the back support around the lateral edges of the seating surface to merge with the upper seating surface. A supplementary base has a peripheral edge to engage the periphery of the lower surface to provide increased lift. The base has an aperture dimensioned to receive the back support and side supports so that the base may be inverted and nested on the upper seating surface.

The present disclosure is directed to an adjustable chair assembly that includes two separate seat assemblies and two separate footrests. The two seat assemblies can be attached to each other in a first state and can be detached from each other in a second state via engagement with an actuator. The adjustable chair assembly can include a plurality of actuator assemblies that can be configured to adjust a recline angle of at least one of the seat assemblies, a height of a frame member, and other aspects of the adjustable chair assembly.

In one example, a highchair has a seat and a base. The base is attached to the seat such that, when the base is disposed on a surface, the base supports the seat above the surface. The base has a plurality of legs that are rotatable so as to transition the highchair between a raised position and a lowered position. In the raised position, the seat is disposed at a first height and the plurality of legs together define a first footprint that has a first cross-sectional area in a select plane. In the lowered position, the seat is disposed at a second height, lower than the first height, and the plurality of legs together define a second footprint that has a second cross-sectional area in the select plane that is less than the first cross-sectional area.

A portable booster seat for supporting a child on a chair having a retractable clamping arm that is extendable to an underside surface of a chair seat and selectively moveable to clamp the booster seat to the chair.

A child booster seat assembly includes a base seat, an upper seat and a latch mechanism. The upper seat is detachably installed on the base seat. A first guiding structure and a second guiding structure are formed on the upper seat and the base seat respectively and for cooperating with each other to guide the upper seat to be aligned with the base seat. The first guiding structure protrudes from a rear bottom portion of the upper seat. The latch mechanism includes an actuator movably disposed on the upper seat, a first engaging structure and a second engaging structure. The first engaging structure is movably disposed on the first guiding structure and connected to the actuator. The second engaging structure is formed inside the second guiding structure and located at a position corresponding to the first engaging structure for engaging with or disengaging from the first engaging structure.

Disclosed are a baby carrier, a swing mechanism, and a seat connecting structure. The baby carrier includes a main frame, a swing bracket assembly, and a seat. The main frame is configured to be supported by ground. The seat is pivotally connected to the main frame through the swing bracket assembly, so as to be able to swing backwards and forwards relative to the main frame.

A convertible furniture and toy assembly for children, which has a symmetrical base unit and replaceable module elements that can be attached thereto. The base unit contains two side units arranged at an equal distance from its plane of symmetry and at least two connecting elements connecting the two side units. The convertible furniture and toy assembly for children is provided with a stabilizing system in which the side unit of the base unit contains a first side element, a second side element, and an intermediate side element connecting them. The first side element is arranged at a predetermined distance X and the second side element is arranged at a predetermined distance X+Y+V from the plane of symmetry. The stabilizing system preferably also contains at least one connecting member and module elements that can be installed symmetrically on the base unit.

A children's dining chair includes a base, handles, and a backrest. A left side, a right side, and a rear side of the base are provided with blocking walls. A first storage slot is defined in the blocking walls. The handles are detachably arranged on the left side and the right side of the base. The backrest is detachably arranged on the rear side of the base. When the handles and backrest are disassembled from the base, the handles and the backrest are capable of being stored in the first storage slot.
