The invention is directed to a child seat comprising: an outer shell supporting an inner shell therein, the inner shell and the outer shell together defining a child protection region within the seat; an adjustment mechanism disposed between the inner shell and the outer shell defining a trajectory of movement for the inner shell relative to the outer shell, wherein relative movement between the inner shell and the outer shell along the trajectory of movement adjusts a size and a shape of the child protection region of the seat.

Systems and methods for a child seat in accordance with embodiments of the invention are disclosed. In one embodiment, a child seat includes an outer shell having a seat portion and a back portion, and a base assembly having a mechanism for mounting the car seat and a recline mechanism.

Provided is a child safety seat, comprising a seat body and a five-point safety belt disposed on the seat body, wherein the seat body comprises a housing, the five-point safety belt comprises a safety belt buckle, and the housing is internally provided with a storage slot used for storing the safety belt buckle; the seat body further comprises a head support assembly disposed on the housing in a sliding up and down manner, the head support assembly having a predetermined position; when the safety belt buckle is placed in the storage slot, the head support assembly is allowed to be higher than the predetermined position; according to the child safety seat, the five-point safety belt or a car safety belt can be correspondingly selected for use based on the size of a child, and the height of a head support can be adjusted in a corresponding range.

Provided is a child safety seat, comprising a seat body and a five-point safety belt disposed on the seat body, wherein the seat body comprises a housing (1), the five-point safety belt comprises a safety belt buckle (2), and the housing is internally provided with a storage slot (11) used for storing the safety belt buckle (2); the seat body further comprises a head support assembly (3) disposed on the housing (1) in a sliding up and down manner, the head support assembly having a predetermined position; when the safety belt buckle (2) is placed in the storage slot (11), the head support assembly (3) is allowed to be higher than the predetermined position; according to the child safety seat, the five-point safety belt or a car safety belt can be correspondingly selected for use based on the size of a child, and the height of a head support can be adjusted in a corresponding range.

The invention relates to a child seat for attaching to a motor vehicle seat, comprising a seat region, a backrest, a headrest having at least one belt guide, and a headrest inclination adjustment device for adjusting an inclination of the headrest relative to the backrest.

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.

Embodiments of a car seat include an outer protective shell, an inner seat, a suspension system connecting and permitting relative movement between the inner seat and the outer protective shell. The suspension system may include a plurality of deformable metal straps. Also, embodiments of a car seat system include a frame constructed to couple to a vehicle seat. The frame has a vertical portion that extends upwardly substantially along a vehicle seatback. The vertical portion extends at least half of the height of vehicle seatback. Also, the system includes a car seat constructed to couple to the frame.

A pushchair seat for mounting on a pushchair chassis is comprised of a seating surface and a backrest, wherein the backrest has a distal section and a proximal section which can be rotated relative to the distal section in such a way that the backrest can be folded up from an unfolded backrest usage position into a collapsed backrest storage position.

An adjustment system for adjusting relative position between a car safety seat and an onboard backrest is introduced and has a controlling unit to receive a first monitoring signal or a second monitoring signal in response to pressure change, pull change or displacement. The adjustment system allows a backrest of the car safety seat to closely lean against the onboard backrest so that the child sitting on the car safety seat is well protected when in a sudden brake or a collision.

A child safety seat includes a support base having a stop, a sliding carriage, a rotary platform having a follower part, and a child seat. The sliding carriage is slidable relative to the support base between a retracted and an extended position, and the child seat and the rotary platform are rotatable together relative to the sliding carriage and the support base between a forward and a rearward facing position. While the sliding carriage is in a position other than the retracted position, a rotational movement of the child seat and the rotary platform is limited by a contact between the follower part and the stop that keeps the child seat and the rotary platform apart from the forward facing position, and the stop is located outside a travel path of the follower part when the sliding carriage is in the retracted position for rotation of the rotary platform to the forward facing position.
