Abstract

A child safety seat assembly includes a detachable child seat and a base. The child seat has a seatback, and a foremost end opposite to the seat back. The base includes a shell body, an adjustable platform and a latch mechanism. The shell body has a first and a second end edge opposite to each other. The first end edge is at a height that is greater than that of the second end edge. The adjustable platform is operable to releasibly attach with the child seat. The adjustable platform and the child seat attached with each other are movable in unison between a first state where the foremost end is near the first end edge, and a second state where the foremost end is away from the first end edge and below the first end edge of the shell body.

Claims

1. A child safety seat assembly comprising:

a detachable child seat having a seatback, and a foremost end opposite to the seatback; and

a base including;

a shell body having a first and a second end edge opposite to each other, a bottom adapted to provide stable resting on a support surface, and an upper surface extending between the first and second end edges of the shell body, wherein the first end edge is at a height relative to the bottom that is greater than that of the second end edge, and the shell body extends along a lengthwise axis between the first and second end edges;

an adjustable platform assembled with the shell body for displacement along the lengthwise axis relative to the shell body and operable to releasibly attach with the child seat, wherein the adjustable platform and the child seat attached with each other are movable in unison along the upper surface between a first state where the foremost end of the child seat is at a first position near the first end edge of the shell body, and a second state where the foremost end of the child seat is at a second position away from the first end edge of the shell body and lying below the first position and the first end edge of the shell body, a child when sitting on the child seat facing the foremost end, and the foremost end of the child seat in the first and second states remaining between the first and second end edges of the shell body along the lengthwise axis; and

a latch mechanism disposed between the upper surface of the shell body and the adjustable platform, wherein the latch mechanism is operable to lock the adjustable platform with the shell body in any of the first and second states.

2. The child safety seat assembly according to claim 1, wherein the child seat is more reclined in the first state than in the second state.

3. The child safety seat assembly according to claim 1, wherein the shell body includes two elongated arms that are respectively arranged at a left and a right side of the shell body and extend above the upper surface to the first end edge of the shell body.

4. The child safety seat assembly according to claim 3, wherein the adjustable platform includes a support body disposed on the upper surface of the shell body and between the two elongated arms.

5. The child safety seat assembly according to claim 4, wherein the support body is provided with two sockets having guide slots through which the two elongated arms are respectively arranged, the sockets being movable along the elongated arms during adjustment of the adjustable platform relative to the shell body.

6. The child safety seat assembly according to claim 5, wherein at least one of the sockets is assembled with a release button that is operatively connected with the latch mechanism.

7. The child safety seat assembly according to claim 4, wherein the latch mechanism is arranged in a region between the two elongated arms.

20. The child safety seat assembly according to claim 1, wherein the first end edge of the shell body is configured to abut adjacent to a seatback of a vehicle seat when the child safety seat assembly is installed on the vehicle seat.

8. A safety child seat assembly comprising:

a detachable child seat having a seatback, and a foremost end opposite to the seatback; and

a base including;

a shell body having a first and a second end edge opposite to each other, a bottom adapted to provide stable resting on a support surface, and at least one elongated arm extending to the first end edge, wherein the first end edge is at a height relative to the bottom that is greater than that of the second end edge, and the shell body extends along a lengthwise axis between the first and second end edges;

an adjustable platform assembled with the shell body and operable to releasibly attach with the child seat, the adjustable platform including a socket that has a guide slot through which the elongated arm is arranged, the socket being movable along the elongated arm during adjustment of the adjustable platform relative to the shell body; and

a latch mechanism operable to releasibly lock the adjustable platform with the shell body;

wherein the adjustable platform and the child seat attached with each other are operable to slide in unison relative to the shell body to cause the foremost end of the child seat to move away and downward from the first end edge of the shell body, a child when sitting on the child seat facing the foremost end, and the foremost end of the child seat remaining between the first and second end edges of the shell body along the lengthwise axis when the foremost end of the child seat moves away and downward from the first end edge of the shell body.

9. The child safety seat assembly according to claim 8, wherein the foremost end of the child seat is movable between a first position near the first end edge of the shell body, and a second position away from and below the first end edge of the shell body, and the child seat is more reclined when the foremost end is in the first position than when the foremost end is in the second position.

10. The child safety seat assembly according to claim 8, wherein the shell body further has an upper surface, the adjustable platform includes a support body disposed on the upper surface, and the latch mechanism is arranged between the upper surface and the support body.

11. The child safety seat assembly according to claim 10, wherein the elongated arm extends above the upper surface of the shell body at an angle relative to the bottom of the shell body.

12. The child safety seat assembly according to claim 8, wherein the socket is assembled with a release button that is operatively connected with the latch mechanism.

13. A child safety seat assembly comprising:

a detachable child seat having a seatback, and a foremost end opposite to the seatback; and

a base including;

a shell body having a first and a second end edge opposite to each other, a lengthwise axis extending from the first to the second end edge, and a bottom adapted to provide stable resting on a support surface, wherein the first end edge is adjacent to a highest point of the shell body;

an adjustable platform assembled with the shell body and operable to releasibly attach with the child seat; and

a latch mechanism operable to releasibly lock the adjustable platform with the shell body;

wherein the adjustable platform and the child seat attached with each other are operable to slide in unison along the lengthwise axis to displace the foremost end of the child seat either downward and away from the first end edge of the shell body, or upward and toward the first end edge, a child when sitting on the child seat facing the foremost end, and the foremost end of the child seat remaining between the first and second end edges of the shell body along the lengthwise axis when the foremost end of the child seat is displaced downward and away from the first end edge of the shell body or upward and toward the first end edge of the shell body.

14. The child safety seat assembly according to claim 13, wherein the foremost end of the child seat is movable between a first position near the first end edge of the shell body, and a second position away from and below the first end edge of the shell body, and the child seat is more reclined when the foremost end is in the first position than when the foremost end is in the second position.

15. The child safety seat assembly according to claim 13, wherein the shell body includes an upper surface, and two elongated arms that are respectively arranged at a left and a right side of the shell body and extend above the upper surface to the first end edge of the shell body.
