The present disclosure discloses a child safety seat, which is for being installed on a vehicle seat. The child safety seat includes a base having an anchor part connected to the vehicle seat; a seat coupled to the base; a top rod fixed to the rear of the base; a tether assembly including a top tether and a tether fixing portion that are connected with each other, the top tether being connected with the top rod and the tether fixing portion being connected with the vehicle seat; and an alarm device including a switch which can be triggered when the top tether is tightened. The present disclosure also discloses a tether assembly and a support structure. The child safety seat can conveniently prompt that it is not correctly fixed, and can be conveniently fixed and adjusted, thereby improving the safety and riding comfort of the child safety seat.

A child safety seat comprising a seat shell comprising a seat portion and a back portion, an adjustable backrest configured to be moveable with respect to the seat shell between a first position, where at least a portion of the backrest is moved away from the back portion and closer to a front edge of the seat portion, reducing the available seating area for an occupant of the seat, and a second position, where at least a portion of the backrest is moved toward the back portion and further from the front edge of the seat portion, increasing the available seating area for the occupant of the seat.

The present disclosure relates to a child safety seat. The child safety seat includes: a seat base defining a receiving groove on a front edge thereof; a buckle connected to the seat base through a crotch belt, and a shape of the buckle being matched with the receiving groove; and a seat cushion covering on the seat base and defining a slot to allow the buckle to pass through. When the buckle is no longer used, the buckle can be received in the receiving groove without removing the buckle, which does not affect the normal use of the seat base, and improves the convenience of using the child safety seat for users.

A system for converting an infant child seat to a stroller may include an infant child seat, a wheeled frame, and a handle. The handle is coupled to the infant child seat and configured to manipulate the wheeled frame when the infant child seat is mounted. A wheeled frame, being removably securable to an infant child seat, may include a frame movable between a folded storage configuration and an expanded stroller configuration. The frame is configured to removably receive an infant child seat and includes a plurality of wheels. The wheeled frame does not define a handle. A method of converting an infant child seat including a handle to a stroller may include coupling the seat to a wheeled frame. The method further includes manually actuating, by a first hand of a user, the handle into a stroller position. The seat coupled to the frame are operable as a stroller.

An apparatus for calming a baby in an interior of a vehicle has a heartbeat sensor device (11, 12, 13) configured to capture a heartbeat input signal that depends on the heartbeat of an occupant in an interior (18) of a vehicle (10). A heartbeat signal processing device (14) is configured to produce a heartbeat output signal that depends on the heartbeat input signal. A calming signal output device (15, 16, 17) is configured to output a calming signal that depends on the heartbeat output signal and that is perceivable by a baby in the interior (19) of the vehicle (10). The apparatus is to configured to output the calming signal, at least intermittently, directly during the capture of the heartbeat input signal.

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 side impact protection linkage mechanism (100) includes a side impact protection block (10). The side impact protection block (10) is pivotally connected to a side wall (20) of a safety seat base (200) and has a folded position attached to the side wall (20) and an expanded position away from the side wall (20). A support frame (11) is disposed in the side wall (20). The support frame (11) is equipped with an engaging member (12) and a linkage member (13). An end of the engaging member (12) is pivotally connected to the support frame (11) and another end of the engaging member (12) has a lock portion (120) slidably protruding from the side wall (20). The engaging member (12) is detachably engaged with the side impact protection block (10) through the lock portion (120). The linkage member (13) is disposed below the engaging member (12) and capable of sliding upward and downward along the support frame (11). The linkage member (13) is configured to drive the engaging member (12) rotate downward.

A child seat for a vehicle. The child seat is configured for holding a child within an interior compartment of the vehicle, where the child seat includes an attachment arrangement adapted for attaching the child seat to a vehicle door structure.

A safety seat for a vehicle includes a rigid frame concavely shaped to accommodate a person, and a headrest shaped to accommodate a head of the person. The headrest has two headrest side panels flexibly connected to the rigid frame. A horizontally disposed lever is positioned at the back of the rigid frame which is pushed by an external side impact. A vertically disposed lever adjacent to the horizontally disposed lever is pushed vertically by movement of the horizontally disposed lever, and moves the two headrest side panels to a closed position on the sides of the head.
