A control circuit according to the application is suitable for controlling an tilt angle of a carrier, wherein the control circuit includes: a sensor module, sensing a current angle of the carrier with a horizontal plane; a drive module, driving and adjusting the tilt angle of the carrier; and a control module, electrically connected to the sensor module and the drive module to output a control signal based on the current angle of the carrier with the horizontal plane, so as to dynamically adjust the tilt angle of the carrier. The application also provides a child safety seat and a method for adjusting the tilt angle between the seat and the base of the child safety seat.

Disclosed herein is a car seat comprised of a base and a shell. The base includes a receiving portion and a backing portion. The seat shell includes a seat back and a seat bottom having a lower portion. The seat bottom is convex and interfaces with the receiving portion of the base. The seat shell is rotatable with respect to the base. The seat shell is selectively positionable between a plurality of orientations. The seat shell includes handles configured to independently unlock rotation of the seat shell with respect to the base. The lower portion of the seat shell includes an aperture configured to receive at least a portion of a projection of the base therethrough.

A support base for a child safety seat includes a shell, a belt clamp and a latching mechanism. The shell is adapted to receive a child seat thereon, and has a panel at an end thereof and a belt anchoring region adjacent to the panel, the belt anchoring region including a first and a second surface, the second surface being supported by the panel and connected with the first surface. The belt clamp is pivotally connected with the shell, and is operable to clamp a first and a second belt portion respectively adjacent to the first and second surface. The latching mechanism is operable to lock the belt clamp in a clamping state.

A pram may be used to transport babies and relatively young infants, and may provide a relatively horizontal surface for the baby or infant to be transported upon in a flat lying position. A pram may also be used to transport relatively older infants, and may provide a seat arrangement for the infant to be transported in a sitting position. However, babies and infants grow quickly and may outgrow conventional prams within a year or two years. Therefore, a parent or guardian must typically provide several prams for their child. Furthermore, a pram offering optimal comfort or safety may not be convenient when travelling or for city living. An aspect of the present disclosure includes a child transportation system comprising a frame 100, wherein the frame 100 is width adjustable between a relatively narrow compact arrangement and a relatively wide comfort arrangement. The frame 100 also includes an infant carrier attachment mechanism 500 configured and arranged to permit, in use, a seat 200 or an infant carrier module 300 to be releasably attached to the frame 100.

A support base for a child safety seat includes a support leg operable to retract and expand at a bottom of the support base, a first and a second locking mechanism, and a linking assembly. The support leg includes multiple segments, and a first and a second sliding connection each of which respectively coupling two adjacent ones of the segments. The first locking mechanism includes a first latch operable to lock the first sliding connection, and a first actuating part operable to urge the first latch to move for unlocking the first sliding connection. The second locking mechanism includes a second latch operable to lock the second sliding connection, and a second actuating part operable to urge the second latch to move for unlocking the second sliding connection. The linking assembly couples the two locking mechanisms so that the first and second sliding connections can be concurrently unlocked.

A power supply device for a vehicle child seat includes an anchor housing mounted on a rear seat, an anchor and a power supply connector, which are positioned within the anchor housing, a latch bar mounted on a child seat and fastened on the anchor in a locked manner, a connector module slidably fastened to the latch bar, and a power connection connector integrally combined with the connector module and removably fastened to the power supply connector.

An infant carrier is included in a child restraint that may also include a carrier-mount base adapted to be anchored to a passenger seat in a vehicle. The infant carrier includes a shell for holding an infant and a carry handle coupled to the shell and adapted to be gripped by a caregiver.

A seat belt fixing device is provided. The seat belt fixing device includes a top rod body and a seat belt clamp. The top rod body is pivotally disposed and selectively locked to a seat. The seat belt clamp is disposed on the seat and includes a first clamping element and a second clamping element. The second clamping element is coupled to the top rod body for being rotated to a locked position to clamp a seat belt in conjunction with the first clamping element.

A child safety seat comprising a base and a body rotatably connected to the base for providing a seating space. The base is rotatably connected to the body via a rotating shaft. The child safety seat further comprises an electrical pivoting structure including a base pivoting member for electrically connecting to a base electrical device in the base, and a body pivoting member for electrically connecting to a body electrical device in the body. The base pivoting member is coupled to the base and has a base conductive part. The body pivoting member is coupled to the body and has a body conductive part. The base conductive part and the body conductive part are rotatably and electrically connected in the rotating shaft. The base electrical device and the body electrical device are electrically connected to each other via electrical connection of the base conductive part and the body conductive part.

A child safety seat is provided and includes a base, a seat body and a notifying system. The seat body is movable relative to the base between a first position and a second position. The notifying system includes at least one actuated device disposed on one of the base and the seat body, an actuating component disposed on another one of the base and the seat body, and a notifying device electrically connected to the at least one actuated device. When the seat body reaches at least one of the first position and the second position, the actuating component actuates the at least one actuated device, so that the at least one actuated device is actuated to generate different types of actuating signals. The notifying device generates different types of notifying signals when the at least one actuated device generates the different types of actuating signals.
