Abstract

A child safety seat includes a support base, a seat shell positionable on the support base, a front end part rotatable relative to the seat shell between a retracted position 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 and two side portions, 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. 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 support base adapted to be installed on a vehicle seat;
a seat shell positionable on the support base, the seat shell having a front end, a seat portion, a backrest 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, whereby an interior space for receiving a child is defined at least partially between the two sidewalls, wherein each of the two sidewalls has an inner cavity, two opposite sidewall surfaces and a sidewall edge, one of the two sidewall surfaces facing the interior space of the seat shell and the other one of the two sidewall surfaces facing an outer side of the seat shell, the sidewall edge being located above the seat portion and respectively connected with the two sidewall surfaces, the sidewall edge extending to the front end of the seat shell, the inner cavity of each of the two sidewalls being delimited at least partially by the two sidewall surfaces and the sidewall edge thereof;
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, 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 and the two side portions of the front end part being respectively received at least partially inside the inner cavities of the two sidewalls 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, 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; 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 front end part is pivotally connected with the two sidewalls about a pivot axis that is located above the seat portion.

5. 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 two pivot shafts.

6. The child safety seat according to claim 5 , 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.

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

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

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

10. The child safety seat according to claim 9 , wherein the release actuator is provided on the transversal portion of the front end part.

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

12. The child safety seat according to claim 11 , 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 about half the first distance.

13. A child safety seat comprising:
a support base adapted to be installed on a vehicle seat;
a seat shell positionable on the support base, the seat shell having a front end, a seat portion, a backrest 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, whereby an interior space for receiving a child is defined at least partially between the two sidewalls;
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, 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;
wherein each of the two sidewalls has an inner cavity, 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, and 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; and
wherein the seat shell is adjustable relative to the support base to a forward facing position, a rearward facing position and a sideways facing position, the front end part sideways protruding a first distance from the support base when the seat shell is in the sideways facing position and the front end part in the deployed position, and the front end part sideways protruding a second distance from the support base when the seat shell is in the sideways facing position and the front end part in the retracted position, the second di
