A child restraint is adapted to set on a passenger seat in a vehicle. The child restraint includes a seat bottom, a seat back, and a movable headrest.

A child safety seat includes a seat base assembly, a seat body assembly, and a sled assembly coupled to the seat base assembly and the seat body assembly. The sled assembly is configured to allow linear movement of the seat body assembly relative to the seat base assembly when the seat is exposed to impact forces, and includes a modular energy absorber configured to reduce the impact forces on an occupant of the seat body assembly.

A child safety seat including a base; a rotatable seat above the base and having a forward-facing mode and a rearward-facing mode; and a misuse prevention mechanism on the base and the seat and having a locked state and a released state, wherein when the misuse prevention mechanism is in the locked state and the seat is between the rearward-facing mode and a rotation threshold angle, a rotation angle of the seat in the first direction cannot be greater than the rotation threshold angle; and wherein when the misuse prevention mechanism is in the released state and the seat is between the rearward-facing mode and the rotation threshold angle, the rotation angle of the seat can be greater than the rotation threshold angle; the first direction is a rotation direction from the rearward-facing mode to the forward-facing mode.

A carrier body includes a main body, a headrest and a height adjusting mechanism. An engaging portion is formed on the main body. The headrest is movably disposed on the main body. The height adjusting mechanism is installed on the headrest and for cooperating with the engaging portion to adjust a height of the headrest relative to the main body. The height adjusting mechanism includes a driving component slidably disposed on the headrest and a locking component. The locking component includes a rotating connecting portion rotatably connected to the headrest, a locking portion and a driving connecting portion movably connected to the driving component. The driving component slides to drive the locking component to rotate relative to the headrest to drive the locking portion to engage with or disengage from the engaging portion.

A base structure (100) adapted for a seat body of a child safety seat is provided and includes a first base (1), a second base (2), a locking component (3) and a releasing mechanism (4). The second base (2) is pivotally connected to the first base (1) and located above the first base (1). A locking hole (21) is formed on a bottom portion of the second base (2). The locking component (3) is slidably disposed on the first base (1). An end of the locking component (3) is for engaging with an end of the locking hole (21). An end of the releasing mechanism (4) is located inside the second base (2) and slidably disposed on another end of the locking hole (21). The releasing mechanism (4) is operated to push the locking component (3) to disengage from the locking hole (21) for unlocking the second base (2), so as to allow the second base (2) to pivot relative to the first base (1).

A child safety seat includes a seat base assembly, a seat body assembly, and a sled assembly coupled to the seat base assembly and the seat body assembly. The sled assembly is configured to allow linear movement of the seat body assembly relative to the seat base assembly when the seat is exposed to impact forces, and includes a modular energy absorber configured to reduce the impact forces on an occupant of the seat body assembly.

A child safety seat assembly includes a support base, and a child carrier operable to detachably assemble with the support base. The support base has a shell body that defines a receiving area and includes an upright surface raising upward from a bottom surface, the shell body being assembled with a latch located adjacent to the upright surface. The child carrier includes a seat shell having a foot portion protruding downward, the foot portion having an interior in which are assembled a release arm and a fixed rod. The foot portion is placed on the bottom surface in the receiving area and the latch engages with the rod when the child carrier is locked with the support base, and the release arm is operable to push the latch to disengage from the rod for removal of the child carrier from the support base.

A child restraint includes a seat base and a juvenile seat. The seat base is adapted to rest on a vehicle seat. The juvenile seat is coupled to the seat base. The seat base includes a seat-base foundation that supports the juvenile seat, and an energy-management pad coupled to the seat-base foundation.

A side collision protection mechanism includes a side collision protection case pivotally connected to a side region of a child safety seat and a locking element movably set in the side collision protection case and having a locking end detachably locked to the side region. The locking end is fully locked to the side region when the side collision protection case is in an extended state and subjected to a side impact force, or partially locked to the side region when the side collision protection case is in the extended state but not subjected to any side impact force. The side collision protection case can be pushed pivotally relative to the side region to switch from the extended state to a folded state and to release the locking end from its locking to the side region. A child safety seat with the above side collision protection mechanism is also disclosed.
