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.

First claim

What is claimed is:

1. A child safety seat comprising:
a support base suitable for placement on a vehicle seat, the support base including 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;
a rotary platform pivotally connected with the bearing portion of the support base about a pivot axis; and
a child seat 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;
wherein the support base further includes a first and a second flange portion vertically spaced apart from each other, the second flange portion being located below the first flange portion and each of the first and second flange portions having a curved shape that extends transversally from a left to a right side of the support base, the seat unit comprised of the child seat and the rotary platform being respectively engaged with the first and second flange portions in the forward facing position with the first flange portion located adjacent to a shoulder support region of the child seat, and the seat unit being engaged with the second flange portion and disengaged from the first flange portion in the rearward facing position.

2. The child safety seat according to claim 1 , wherein the bearing portion is movable relative to the anchoring portion between a clamping state for restraining a fastening belt in a region of the belt path between the anchoring portion and the bearing portion, and a release state for facilitating installation or removal of the fastening belt.

3. The child safety seat according to claim 1 , wherein the bearing portion is pivotally connected with the anchoring portion.

4. The child safety seat according to claim 1 , wherein the curved shape of each of the first and second flange portions has a center of curvature adjacent to the pivot axis.

5. The child safety seat according to claim 1 , wherein at least one of the first and second flange portions has a cross-section including a hook shape.

6. The child safety seat according to claim 1 , 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.

7. The child safety seat according to claim 1 , 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.

8. The child safety seat according to claim 7 , wherein the second flange portion is a flange portion of a circular flange that extends around the pivot axis.

9. The child safety seat according to claim 1 , 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.

10. The child safety seat according to claim 9 , wherein the third, fourth and fifth flange portions are fixedly connected with the rotary platform.

11. The child safety seat according to claim 9 , wherein the third and fifth flange portions are two flange portions of a circular flange that extends around the pivot axis.

12. 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.

13. 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.

14. The child safety seat according to claim 13 , 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.

15. The child safety seat according to claim 14 , wherein the recline lock is pivotally connected with the rotary platform.

16. The child safety seat according to claim 14 , 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:
a driving part assembled with the rotary platform, the driving part being rotatable with the rotary platform about the pivot axis and slidable along the pivot axis relative to the rotary platform; and
a release actuator assembled with the bearing portion, the release actuator being operable to urge the driving part to slide along the pivot axis toward an interior of the rotary platform for pushing the recline lock to move from the locking state to the unlocking state.

17. A child safety seat comprising:
a support base suitable for placement on a vehicle seat, the support base including a first and a second flange portion vertically spaced apart from each other, the second flange portion being located below the first flange portion;
a rotary platform pivotally connected with the support base about a pivot axis; and
a child seat connected with the rotary platform, the child seat and the rotary platform being rotatable in unison as a rotatable 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;
wherein the rotatable seat unit comprised of the child seat and the rotary platform is engaged with the first flange portion and the second flange portion in the forward facing position with the first flange portion located adjacent to a shoulder support region of the child seat, and the rotatable seat unit is engaged with the second flange portion and disengaged from the first flange portion in the rearward facing position.

18. The child safety seat according to claim 17 , 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.

19. The child safety seat according to claim 18 , wherein the curved shape of each of the first and second flange portions has a center of curvature adjacent to the pivot axis.
