Various embodiments of the present invention are directed to a convertible children's high chair. According to various embodiments, the convertible high chair generally comprises a first child seat supported above a floor by a high chair frame, and a second child seat configured for being removably coupled to first child seat. The second child seat is configured such that, when detached from the high chair's first child seat, it can be used apart from the high chair as a booster seat (e.g., secured to the seating surface of a standard chair or another support surface). In certain embodiments, the second child seat includes a base surface configured to stably support the second child seat on a separate support surface (e.g., without the need to be attached to or mounted on a separate base or support member).

A child seat includes a seat portion, a backrest frame and a front guard respectively connected pivotally with the seat portion, a latch connected with the seat portion, and a linking part respectively coupled to the latch and the backrest frame, wherein the latch is operable to lock the front guard in position, the latch being engaged with the front guard for locking the front guard and disengaged from the front guard for unlocking the front guard, and the backrest frame being rotatable to cause the latch to unlock for rotation of the front guard.

A child restraint system for securely carrying an infant in a vehicle, said child restraint system comprising a rigid shell that is concave of an inner side and which may be attached to a seat of a vehicle, to provide a unitary element that serves as both seat and back for supporting the infant, and a harness for holding the infant within the concave side of the shell; the unitary element comprising two parts that are hinged together so that the shell folds along a center line running through the rigid shell, each part comprising at least two panels, such that each panel is attachable to adjacent panels to form the rigid shell, or disconnectable from the adjacent panels so that the child restraint system is compactable into a substantially flattened configuration for storage.

Modular furniture systems and methods. The modular furniture systems generally comprise a plurality of support surfaces and/or a plurality of support structures. Each support structure is configured to support the support surface above the ground or floor. In the depicted embodiments, the support surfaces are configured to hold and support a child or infant. In other embodiments, other support surfaces can be used such as tabletops. Generally, the support structures are releasably coupled to the support surface such that they can be assembled and disassembled by the user. The modular furniture system is configured such that each support surface is compatible with a variety of support structures. Similarly, each support structure can be compatible with a variety of support surfaces.

A booster seat can be configured to be adjusted from a full or home booster configuration to a travel configuration or a backless booster configuration. In the full configuration, the booster seat can include a seat base, a seat shell movably coupled to and configured to recline with respect to the seat base, a seat back removably coupled to the seat shell, and soft goods that cover portions of the seat back and the seat shell. In the travel configuration, for example, the booster seat can include the seat back and soft goods without the seat shell and the seat base. In the backless booster configuration, the booster seat can include the seat base and the seat shell without the seat back (e.g., decoupling the seat back from the seat shell). Multiple modes of the booster seat allows for continued use of the seat as the child grows and when travelling.

A foldable child booster seat based on the origami and popup technique. The booster seat is light and easy to be folded flat into a compact form for storage and transport. The foldable booster seat, comprising: a plurality of rigid substrates, each rigid substrate is interconnected to another by one or more integrated hinges or flexible parts allowing the rigid substrate to fold either inward or outward when folding up; wherein when the foldable booster seat is folded flat, the rigid substrates are stacked together; and wherein when the foldable booster seat is folded up, the rigid substrates are arranged to form the shape of a chair or stool.

The reclining child car seat with adjustable head support is a child safety seat. The reclining child car seat with adjustable head support comprises a seat structure, a harness, a locking hinge, and a rack and pinion structure. The seat structure further comprises a bench, a backrest, and a headrest. The reclining child car seat with adjustable head support is a reclining structure that is further defined with a cant. The reclining child car seat with adjustable head support is further configured such that the protective structure of the headrest automatically adjusts as a function of the cant of the reclining structure of the reclining child car seat with adjustable head support. The locking hinge attaches the backrest to the bench such that the backrest rotates relative to the bench. The rack and pinion structure forms a mechanical linkage that adjusts the headrest as a function of the cant. The harness secures the client in the seat structure.

A diaper-changing platform system is disclosed having a structural frame supporting member that receives a platform member. The platform member is configured with interlocking sections configured such that at least one interlocking section can be positioned to project from the platform member to enable an infant or toddler to sit on the interlocking section and is also configured to be positioned such that the platform member defines a generally flat surface enabling an infant or toddler to be positioned lying on the generally flat surface. A stroller for transporting an infant or toddler includes a frame and the diaper-changing platform system. The frame of the stroller receives the diaper-changing platform system when the platform member enables an infant or toddler to sit on at least one interlocking section to enable transporting via the stroller the diaper-changing platform system. A weight supporting system including usage of supporting ribs and exoskeletons is included.
