Abstract

A child safety seat includes a support base, a rotary platform and a child seat. The support base is suitable for placement on a vehicle seat and includes an anchoring portion and a bearing portion connected with each other, the anchoring portion having a belt path for passage of a fastening belt to attach the child safety seat on a vehicle seat. The rotary platform is pivotally connected with the bearing portion of the support base about a pivot axis. The child seat is connected with the rotary platform, wherein the child seat, the rotary platform and the bearing portion are movable in unison relative to the anchoring portion, and the child seat and the rotary platform are rotatable in unison as a seat unit relative to the support base between a plurality of positions including a forward facing position, a rearward facing position and a sideways facing position.

5. The child safety seat according to claim 4, wherein each of the first and second flange portions has a curved shape that extends transversally from a left to a right side of the support base.

6. The child safety seat according to claim 5, wherein the curved shape of each of the first and second flange portions has a center of curvature adjacent to the pivot axis.

7. The child safety seat according to claim 4, wherein at least one of the first and second flange portions has a cross-section including a hook shape.

8. The child safety seat according to claim 4, wherein the anchoring portion extends above the bearing portion and is fixedly connected with the first and second flange portions, the first and second flange portions being located above the bearing portion.

9. The child safety seat according to claim 4, wherein the anchoring portion extends above the bearing portion and is fixedly connected with the first flange portion, and the second flange portion is fixedly connected with the bearing portion.

10. The child safety seat according to claim 9, wherein the second flange portion is a flange portion of a circular flange that extends around the pivot axis.

11. The child safety seat according to claim 4, wherein the seat unit comprised of the child seat and the rotary platform has a front portion and a rear portion, the front portion having a third flange portion, the rear portion having a fourth and a fifth flange portion vertically spaced apart from each other, the fourth and fifth flange portions being respectively engaged with the first and second flange portions in the forward facing position, and the third flange portion being engaged with the second flange portion and the fourth flange portion disengaged from the first flange portion in the rearward facing position.

12. The child safety seat according to claim 11, wherein the third, fourth and fifth flange portions are fixedly connected with the rotary platform.

13. The child safety seat according to claim 11, wherein the third and fifth flange portions are two flange portions of a circular flange that extends around the pivot axis.

14. The child safety seat according to claim 1, wherein the bearing portion includes a seat rotation lock and a release actuator, the seat rotation lock being operable to lock the child seat and the rotary platform in the forward facing position and the rearward facing position, and the release actuator being operable to urge the seat rotation lock to move to an unlocking state for rotation of the child seat and the rotary platform relative to the support base.

15. The child safety seat according to claim 1, wherein the child seat is movably connected with the rotary platform, the child seat being slidable relative to the rotary platform and the support base for recline adjustment.

16. The child safety seat according to claim 15, wherein the rotary platform includes a recline lock movable between a locking and an unlocking state, the recline lock being engaged with the child seat in the locking state for locking the child seat in position with respect to the rotary platform, and the recline lock being disengaged from the child seat in the unlocking state for recline adjustment of the child seat relative to the rotary platform, the recline lock being movable along with the rotary platform during rotation of the child seat and the rotary platform relative to the support base.

17. The child safety seat according to claim 16, wherein the recline lock is pivotally connected with the rotary platform.

18. The child safety seat according to claim 16, further including a release mechanism operable to urge the recline lock to move from the locking state to the unlocking state, the release mechanism including:
