Abstract

A child safety seat is for use on a vehicle seat. The vehicle seat has a safety belt. The child safety seat includes a seat base, a seat panel, and a seat body. The seat base has a seat assembly portion and a backrest portion. The seat panel is openably pivoted to the seat assembly portion for rotating between an open position and a closed position. The seat body is disposed on the seat panel. When the seat panel rotates to the open position, the safety belt passes over the seat base for attaching the seat base to the vehicle seat. When the seat panel rotates to the closed position, the seat panel clamps the safety belt cooperatively with the seat base.

a seat body disposed on the seat panel;

wherein when the seat panel rotates to the open position, the safety belt passes over the seat base for attaching the seat base to the vehicle seat;

when the seat panel rotates to the closed position, the seat panel clamps the safety belt cooperatively with the seat base.

2. The child safety seat of claim 1, wherein the seat panel is openably hinged to an end of the seat assembly portion away from the backrest portion for rotating together with the seat body between the open position to be tilted relative to the seat assembly portion and the closed position to be detachably fixed on the seat base.

3. The child safety seat of claim 1, wherein the seat base further has two side wing supports;

when the seat panel rotates to the open position, the safety belt is laid across a span between the two side wing supports;

when the seat panel rotates to the closed position, the seat panel pushes the safety belt back and clamps the safety belt cooperatively with the two side wing supports and the seat assembly portion.

4. The child safety seat of claim 3, wherein the two side wing supports extend from two sides of the backrest portion respectively for forming a containing space cooperatively with the seat assembly portion and the backrest portion;

when the seat panel rotates to the open position, the safety belt is located above the containing space;

when the seat panel rotates to the closed position, the seat panel pushes the safety belt back to the containing space and clamps the safety belt in the containing space cooperatively with the two side wing supports and the seat assembly portion, so as to make the safety belt in a concave path.

5. The child safety seat of claim 1, wherein the backrest portion has at least one fixing hole, the child safety seat further comprises a retractable plunger disposed on the seat panel corresponding to the at least one fixing hole and slidable between an engaging position and a retracted position;

when the seat panel is located at the closed position, the retractable plunger pops out to the engaging position to be inserted into the at least one fixing hole for fixing the seat panel to the seat base.

6. The child safety seat of claim 5, wherein during rotation of the seat panel from the open position back to the closed position, the backrest portion biases the retractable plunger to the retracted position;

when the seat panel is located at the closed position to make the retractable plunger aligned with the at least one fixing hole, the retractable plunger pops out to the engaging position to be inserted into the at least one fixing hole for fixing the seat panel to the seat base.

7. The child safety seat of claim 5, wherein the child safety seat further comprises a release button mechanism disposed on the backrest portion for releasing engagement between the at least one fixing hole and the retractable plunger.

8. The child safety seat of claim 7, wherein the release button mechanism comprises a push button and a linkage rod, the push button is slidable between a lock position and a release position on the backrest portion and has a linkage arm extending toward the linkage rod, the linkage rod is rotatably disposed on the backrest portion, and when the pushbutton is pushed from the lock position to the release position, the linkage arm rotates the linkage rod to eject the retractable plunger out of the at least one fixing hole, so as to release engagement between the retractable plunger and the at least one fixing hole.

9. The child safety seat of claim 8, wherein the linkage rod has a first bending portion pivoted to the linkage arm and a second bending portion corresponding to the at least one fixing hole, and when the push button is pushed from the lock position to the release position, the linkage arm rotates the linkage rod via the first bending portion for driving the second bending portion to eject the retractable plunger out of the at least one fixing hole, so as to release engagement between the retractable plunger and the at least one fixing hole.

10. The child safety seat of claim 8, wherein the seat body is rotatably disposed on the seat panel for rotating to a forward facing position, a rearward facing position or a side facing loading position relative to the backrest portion, and when the seat body rotates to the side facing loading position, the push button is exposed from the backrest portion.

11. The child safety seat of claim 1, wherein the seat panel is detachably fixed on the seat base when the seat panel rotates to the closed position, the child safety seat further comprises a release button mechanism disposed on the backrest portion for releasing the seat panel from the seat base, the seat body is rotatably disposed on the seat panel for rotating to a forward facing position, a rearward facing position or a side facing loading position relative to the backrest portion, and when the seat body rotates to the side facing loading position, the release button mechanism is exposed from the backrest portion.

12. The child safety seat of claim 1, wherein the seat panel is detachably coupled to the seat assembly portion to make the seat panel detachable together with the seat body from the seat base, such that the seat panel can be installed on the vehicle seat without the seat base.

13. The child safety seat of claim 12, wherein the child safety seat further comprises at least one pin, the seat panel has a first hole formed thereon corresponding to the at least one pin, the seat assembly portion has a second hole formed thereon corresponding to the first hole;

when the seat panel is assembled with the seat assembly portion to make the first hole aligned with the second hole, the at least one pin is inserted into the first hole and the second hole, so as to make the seat panel openably pivoted to the seat assembly portion;

when the at least one pin is removed from the first hole and the second hole, the seat panel is detachable together with the seat body from the seat assembly portion.

14. A child safety seat for use on a vehicle seat, the vehicle seat having a safety belt, the child safety seat comprising:

a seat base having a seat assembly portion and a backrest portion;

a seat panel openably movable to the seat assembly portion for movement between an open position and a closed position; and

a seat body disposed on the seat panel;

wherein when the seat panel moves to the open position, a belt path for the safety belt is accessible;

when the seat panel moves to the closed position, the belt path for the safety belt is hidden.

15. The child safety seat of claim 14, wherein the seat panel is detachably coupled to the seat assembly portion to make the seat panel detachable together with the seat body from the seat base, such that the seat panel can be installed on the vehicle seat without the seat base.

16. The child safety seat of claim 15, wherein the child safety seat further comprises at least one pin, the seat panel has a first hole formed thereon corresponding to the at least one pin, the seat assembly portion has a second hole formed thereon corresponding to the first hole;

when the seat panel is assembled with the seat assembly portion to make the first hole aligned with the second hole, the at least one pin is inserted into the first hole and the second hole, so as to make the seat panel openably pivoted to the seat assembly portion;

when the at least one pin is removed from the first hole and the second hole, the seat panel is detachable together with the seat body from the seat base.

17. A child safety seat for use on a vehicle seat, the vehicle seat having a safety belt, the child safety seat comprising:

a seat base having a seat assembly portion and a backrest portion;
