Abstract

A child seat includes a seat portion, a backrest frame and a front guard respectively connected pivotally with the seat portion, a latch connected with the seat portion, and a linking part respectively coupled to the latch and the backrest frame, wherein the latch is operable to lock the front guard in position, the latch being engaged with the front guard for locking the front guard and disengaged from the front guard for unlocking the front guard, and the backrest frame being rotatable to cause the latch to unlock for rotation of the front guard.

First claim

What is claimed is:

1. A child seat comprising:
a seat portion;
a backrest frame and a front guard respectively connected pivotally with the seat portion;
a latch connected with the seat portion and operable to lock the front guard in position, the latch being movable relative to the seat portion and the front guard to engage with and disengage from the front guard, wherein the latch is engaged with the front guard for locking the front guard and disengaged from the front guard for unlocking the front guard; and
a linking part respectively coupled to the latch and the backrest frame, the backrest frame being rotatable to cause the latch to unlock for rotation of the front guard.

2. The child seat according to claim 1 , wherein the seat portion has two sidewalls respectively provided at a left and a right side, and the front guard transversally extends above the seat portion with two side end portions of the front guard respectively connected pivotally with the two sidewalls of the seat portion.

3. The child seat according to claim 1 , wherein the front guard is rotatable relative to the seat portion between an unfolded position and a folded position, the latch being engaged with the front guard to lock the front guard in the unfolded position.

4. The child seat according to claim 3 , further including a spring connected with the front guard, the spring biasing the front guard toward the unfolded position.

5. The child seat according to claim 1 , wherein the backrest frame is adjustable relative to the seat portion between a plurality of angular positions including a collapsed position, a first deployed position, and a second deployed position between the first deployed position and the collapsed position.

6. The child seat according to claim 5 , wherein the front guard remains locked in position by the latch during adjustment of the backrest frame between the first and second deployed positions, and the latch is urged to disengage and unlock the front guard when the backrest frame rotates past the second deployed position and advances toward the collapsed position.

7. The child seat according to claim 1 , wherein the latch is pivotally connected with the seat portion, and the linking part is coupled to the backrest frame with a pivotal connection.

8. The child seat according to claim 7 , wherein the linking part is coupled to the latch with a sliding and pivotal connection.

9. The child seat according to claim 8 , wherein one of the linking part and the latch includes an elongate slot, and the other one of the linking part and the latch has a pin disposed through the elongate slot, a course of the pin along the elongate slot is configured to provide a range of travel for the linking part that does not cause the latch to unlock the front guard.

10. The child seat according to claim 9 , wherein the linking part is movable to urge the latch to disengage from the front guard via a contact between the pin and one end of the elongate slot.

11. The child seat according to claim 10 , wherein the front guard has an unfolded position and a folded position, the backrest frame is adjustable relative to the seat portion between a plurality of angular positions including a collapsed position, a first deployed position, and a second deployed position between the first deployed position and the collapsed position, and the contact between the end of the elongate slot and the pin of the latch occurs when the backrest frame rotating toward the collapsed position travels past an intermediate position between the second deployed position and the unfolded position of the front guard.

12. The child seat according to claim 7 , wherein the linking part has an end portion pivotally connected with a side end portion of the backrest frame, the side end portion of the backrest frame having a limiting edge adjacent to the end portion of the linking part, the limiting edge preventing an undesirable displacement of the linking part that is not induced by a rotation of the backrest frame.

13. The child seat according to claim 12 , wherein the limiting edge has a curved shape.

14. The child seat according to claim 1 , further including a spring connected with the latch, the spring biasing the latch to engage with the front guard.

15. The child seat according to claim 1 , wherein the seat portion has a connector operable to detachably engage with a corresponding structure provided on a standing frame of a child supporting apparatus.

16. A child seat comprising:
a seat portion;
a backrest frame and a front guard respectively connected pivotally with the seat portion;
a latch connected with the seat portion and operable to lock one of the backrest frame and the front guard in position, the latch being movable relative to the seat portion and the one of the backrest frame and the front guard to engage with and disengage from the one of the backrest frame and the front guard; and
a linking part respectively coupled to the latch and the other one of the backrest frame and the front guard, the other one of the backrest frame and the front guard being rotatable to cause the latch to unlock.

17. The child seat according to claim 16 , wherein the seat portion has two sidewalls respectively provided at a left and a right side, and the front guard transversally extends above the seat portion with two side end portions of the front guard respectively connected pivotally with the two sidewalls of the seat portion.

18. The child seat according to claim 16 , wherein the backrest frame and the front guard are foldable toward a front of the seat portion.

19. The child seat according to claim 16 , wherein one of the linking part and the latch includes an elongate slot, and the other one of the linking part and the latch has a pin disposed through the elongate slot, a course of the pin along the elongate slot is configured to provide a range of travel for the linking part that does not cause the latch to unlock.

20. The child seat according to claim 19 , wherein the linking part is movable to urge the latch to disengage from the front guard via a contact between the pin and one end of the elongate slot.
