Abstract

A child safety seat includes a seat shell, a front end part rotatable relative to the seat shell between a retracted and a deployed position, and a latching mechanism for locking the front end part in the deployed position. The seat shell has a front end provided with an opening, and two sidewalls respectively protruding at a left and a right side of a seat portion. The front end part has a transversal portion extending along a width direction of the seat shell, and two side portions respectively connected pivotally with the two sidewalls of the seat shell via two pivot shafts spaced apart from each other along the width direction. The transversal portion of the front end part is stowed inside the opening of the seat shell in the retracted position, and extends outside the opening of the seat shell in the deployed position.

First claim

What is claimed is:

1. A child safety seat comprising:
a seat shell having a front end, a seat portion and two sidewalls, the front end having an opening, the two sidewalls respectively protruding at a left and a right side of the seat portion, and an interior space for receiving a child being defined at least partially between the two sidewalls, wherein each of the two sidewalls has two opposite sidewall surfaces that respectively face the interior space of the seat shell and an outer side of the seat shell, and an inner cavity delimited at least partially between the two sidewall surfaces;
a retractable front end part, having a transversal portion and two side portions connected with the transversal portion, the transversal portion extending along a width direction of the seat shell, and the two side portions being respectively connected pivotally with the two sidewalls of the seat shell via two pivot shafts spaced apart from each other along the width direction, each of the two side portions being received at least partially inside the inner cavity between the two opposite sidewall surfaces of a corresponding one of the two sidewalls, whereby the front end part is rotatable relative to the seat shell between a retracted position and a deployed position, the transversal portion of the front end part being stowed and received at least partially inside the opening of the seat shell in the retracted position, and the transversal portion of the front end part extending outside the opening of the seat shell in the deployed position; and
a latching mechanism for locking the front end part in the deployed position.

2. The child safety seat according to claim 1 , wherein the front end part including the transversal portion and the two side portions is formed integrally as a single part.

3. The child safety seat according to claim 1 , wherein the two side portions bend from the transversal portion symmetrical to each other.

4. The child safety seat according to claim 1 , wherein the two side portions of the front end part respectively project forward and downward from the two sidewalls in the deployed position.

5. The child safety seat according to claim 1 , wherein the front end part is pivotally connected with the two sidewalls about a pivot axis that is located above the seat portion.

6. The child safety seat according to claim 1 , wherein each of the two sidewalls further has a sidewall edge connected with the two sidewall surfaces thereof, the inner cavity of each of the two sidewalls being delimited at least partially by the two sidewall surfaces and the sidewall edge thereof.

7. The child safety seat according to claim 6 , wherein each of the two side portions has a front surface that inclines forward and downward and forms a profile extension from the sidewall edge of the sidewall adjacent thereto in the deployed position, the front surface forming an angle with respect to the sidewall edge of the sidewall adjacent thereto in the retracted position.

8. The child safety seat according to claim 1 , wherein each of the two side portions has a coupling end, the coupling ends of the two side portions being respectively disposed inside the inner cavities of the two sidewalls and respectively connected pivotally with the two sidewalls via the two pivot shafts.

9. The child safety seat according to claim 8 , wherein the latching mechanism includes two latches respectively connected with the coupling ends of the two side portions, the two latches being movable relative to the front end part for engaging with or disengaging from the seat shell.

10. The child safety seat according to claim 9 , wherein the two latches are respectively connected slidably with the coupling ends of the two side portions, whereby the two latches are slidable relative to the front end part for engaging with or disengaging from the seat shell.

11. The child safety seat according to claim 9 , wherein the latching mechanism further includes two springs respectively connected with the two latches, the two springs respectively biasing the two latches to move for engaging with the seat shell.

12. The child safety seat according to claim 9 , wherein the latching mechanism further includes a release actuator and two cables, the release actuator being assembled with the front end part and respectively connected with the two latches via the two cables, the release actuator being operable to urge the two latches to move and disengage from the seat shell.

13. The child safety seat according to claim 12 , wherein the release actuator is provided on the transversal portion of the front end part.

14. The child safety seat according to claim 1 , further comprising a support base adapted to be installed on a vehicle seat, the seat shell being positionable on the support base.

15. The child safety seat according to claim 14 , wherein the support base includes a shell body and a rotary platform pivotally connected with each other, the seat shell and the rotary platform being rotatable in unison relative to the shell body so that the seat shell is positionable in different orientations, including a forward facing position, a rearward facing position and a sideways facing position.

16. The child safety seat according to claim 15 , wherein the front end part sideways protrudes a first distance from the support base when the seat shell is in the sideways facing position on the support base and the front end part is in the deployed position, and the front end part sideways protrudes a second distance from the support base when the seat shell is in the sideways facing position on the support base and the front end part is in the retracted position, the second distance being equal to or smaller than the first distance.

17. The child safety seat according to claim 16 , wherein the second distance is smaller than about half the first distance.
