Disclosed herein are child car seats configured to be installed in an associated vehicle using a safety belt of the associated vehicle and a top tether. The child car seat includes a seat shell supported on a base and at least one of a tensioner mechanism and a recline frame. The tensioner mechanism, which may include a panel, is configured to engage and tension each of the safety belt of the associated vehicle and the tether. The recline frame operatively attaches the seat shell to the base such that each of the seat shell and the recline frame are rotatably supported on the base, and the recline frame is further configured to permit the seat shell to recline with respect to the base.

A child safety seat includes a first and a second restraining device, and an alert device and a first and a second switch serially connected in a series circuit. Each of the first and second restraining device is deployable to engage with a corresponding structure provided in a vehicle, each of the first and second restraining devices being operable independently and having an idle position and a deployed position. The first and second switches are respectively coupled operatively to the first and second restraining device, and are respectively closed when the first restraining device is in the deployed position and the second restraining device in the idle position. The alert device is thereby activable to emit an alert signal when the first restraining device is in the deployed position and the second restraining device in the idle position.

A safety seat for a vehicle that comprises a static part attachable to an anchor of a vehicle, at least two energy absorption elements mounted on the static part, each designed to absorb a different amount of energy and a dynamic part adapted to accommodate a child and comprising at least one connector which is engaging at least one of the at least two energy absorption elements, the at least one engaged energy absorption element is adapted to a weight range of a child, so as to absorb impact energy applied on the dynamic part via the static part, thus extending along a longitudinal movement between the static part and the dynamic part.

A system for guiding installation of car seat base and a corresponding car seat includes sensors mounted on the car seat base for detecting a progress in a plurality of sequential installation steps. The installation steps are required for installing the car seat base and the corresponding car seat on a vehicle seat. The car seat base further includes light emitting elements arranged at various locations on the car seat base, each location corresponding to one of the installation steps. A processor is adapted to execute code instructions for, in response to outputs of the sensors, identifying completion of a current installation step. The processor is further adapted to instruct a suitable light emitting element to indicate a location corresponding to an installation step following the current installation step. An anti-rebound device includes a spring or piston that adaptively adjusts in response to an impact and a locking mechanism.

A child safety seat includes a restraining device, and an alert device and a switch serially connected in a series circuit. The restraining device includes a strap and a tether connector provided at a free end of the strap, the restraining device having an idle position and a deployed position, the restraining device being arranged in the deployed position to engage with a corresponding structure provided in a vehicle for restraining the child safety seat. The switch is operatively coupled to the restraining device and has an open state and a closed state, each of the open state and the closed state of the switch uniquely corresponding to one of the idle position and the deployed position of the restraining device. The alert device is activable to emit an alert signal when the series circuit is closed.

A child safety seat includes an ISOFIX assembly and a base. The ISOFIX assembly includes a support foot, a connecting portion, and a sliding rail portion between the support foot and the connecting portion. The connecting portion connects to a car seat. The sliding rail portion includes a first sliding rail portion and a second sliding rail portion connected to the first sliding rail portion. A width of the second sliding rail portion is larger than a width of the first sliding rail portion. The base has a frame assembly which has a sleeve portion slidably sleeved on the sliding rail portion. The sleeve portion includes first and second sleeve portions slidably sleeved on corresponding first and second sliding rail portions. The base is operable to be adjusted telescopically with respect to the ISOFIX assembly through a sliding cooperation between the sliding rail portion and the sleeve portion.

A child safety seat includes a support base, a seat shell positionable on the support base, a front end part rotatable relative to the seat shell between a retracted position and a deployed position, and a latching mechanism for locking the front end part in the deployed position. The seat shell has a front end provided with an opening, and two sidewalls respectively protruding at a left and a right side of a seat portion. The front end part has a transversal portion and two side portions, the transversal portion extending along a width direction of the seat shell, and the two side portions being respectively connected pivotally with the two sidewalls of the seat shell. The transversal portion of the front end part is stowed inside the opening of the seat shell in the retracted position, and extends outside the opening of the seat shell in the deployed position.

A vehicle passenger seat assembly includes a passenger seat and a rail system. The passenger seat includes a seat base and a seat back connected to the seat base. The passenger seat is movable between a seated condition for accommodating a seated passenger and non-seated condition where the passenger seat is tilted forward in a front-rear direction of the vehicle about a forward end portion of the seat base. The rail system is mounted to the seat base and configured to have mounted thereto a child car seat. The rail system is configured to move the child car seat along a lateral direction of the passenger seat between at least two seating locations defined by the passenger seat. The rail system is movable independent of the passenger seat to a forward tilted position to allow for movement of the passenger seat between the seated condition and the non-seated condition.

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.

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.
