Disclosed is an anti-reverse mounting base structure for an infant vehicle seat including the base structure and a placement structure like an infant seat or an infant carrier. The placement structure is mounted on the base structure. The base structure includes a chassis and a rotating assembly provided with a pressure block assembly. The pressure block assembly is mounted movably up and down on the rotating assembly. When the placement structure is mounted on the base structure, it drives the pressure block assembly to move downward. The chassis is provided with a mounting slot and forms a blocking surface. The mounting slot is configured to engage with the pressure block assembly moving downward to mount the placement structure on the base structure. The blocking surface is configured to prevent the pressure block assembly from moving downward, thereby restricting the placement structure from being mounted on the base structure. When the placement structure is oriented correctly, it is mounted by a downward movement of the pressure block assembly engaging with the mounting slot of the chassis. When the placement structure is oriented incorrectly, the blocking surface restricts the downward movement of the pressure block assembly, thereby preventing the placement structure from being placed on the base structure.

A child vehicle seat comprises a base detachably connectable to a vehicle seat, a rotating part being rotatable with respect to the base about a rotation axis from at least a forward facing position or a rearward facing position seen in a driving directing of the vehicle in use to a side facing position directed to a door of the vehicle and vice versa, a sliding part being slidable with respect to the base in a sliding direction substantially perpendicular to the driving direction of the vehicle, and child seat connected to the base via the sliding part and the rotating part. The child seat and the sliding part are slidable together with respect to the rotating part, wherein the child vehicle seat comprises first locking means to detachably lock the rotating part to the base in the at least forward facing position or rearward facing position, as well as second locking means to detachably lock sliding of the sliding part with respect to the rotating part.

The present invention discloses a multi-mode seat belt selection control mechanism and a multi-mode seat belt-equipped child seat, where the selection control mechanism includes a support mechanism for supporting a child seat belt when deployed and capable of being folded; one side of the support mechanism is provided with a limiting mechanism for limiting a headrest height and a control mechanism for controlling deployed and folded states of the support mechanism while causing the limiting mechanism to synchronously adjust the headrest height, enabling the support mechanism to correspond to a low headrest height when deployed and to a high headrest height when folded; and the selection control mechanism is capable of limiting a headrest adjustment height and linking a headrest height limit with the deployed and folded states of the support mechanism, thereby ensuring appropriate use of the child seat belt and preventing safety risks to children due to misuse of the child seat belt by a user.

A child vehicle seat (1) comprising a base (2) and a seat (3) being rotatable about a rotation axis (5) with respect to the base from at least a first rotation position to a second rotation position and vice versa. The seat is provided with means for holding a child in the seat, which means being adjustable with respect to a child sitting in the seat. The adjustable means are adjustable from a first operation position to a second operation position by rotating the seat with respect to the base between the first rotation position and the second rotation position and/or vice versa.
