Abstract

A child safety seat assembly comprises a base including a plurality of protruding sidewalls, and a seat movably assembled with the base including a plurality of anchoring slots adapted to retain a portion of a safety belt, wherein seat is movably adjustable between an erected position and a reclined position relative to the base. Some of the anchoring slots can be selectively obstructed by the sidewalls of the base when the seat is adjusted to a different inclination relative to the base. As a result, erroneous operations for securing the seat assembly with a safety belt can be prevented, and the seat assembly can be safer in use.

Claims

1. A child safety seat assembly comprising:

a base including a plurality of protruding sidewalls; and

a seat movably assembled with the base and including a plurality of anchoring slots adapted to retain a portion of a safety belt;

wherein the seat is movably adjustable between an erected position and a reclined position relative to the base, and the seat is operable to cause the base to selectively obstruct at least one of the anchoring slots.

2. The child safety seat assembly according to claim 1, wherein the anchoring slots comprise:

a first anchoring slot located at an upper side of a backrest of the seat;

a second anchoring slot located at a lower side of the backrest; and

a third anchoring slot located on a bottom of the seat.

3. The child safety seat assembly according to claim 2, wherein at least one of the sidewalls on the base obstructs the third anchoring slot when the seat is in the erected position relative to the base.

4. The child safety seat assembly according to claim 2, wherein at least one of the sidewalls on the base obstructs the second anchoring slot when the seat is in the reclined position relative to the base.

5. The child safety seat assembly according to claim 2, wherein a set of the first, second and third anchoring slots is respectively provided in each of two parallel rail portions provided on a rear of the backrest and a bottom of the seat, the rail portions having a curved profile and extending from the upper side of the backrest to the bottom of the seat.

6. The child safety seat assembly according to claim 5, wherein the two rail portions, including the first, second and third anchoring slots, are located at symmetrical positions on a left and right side of the backrest.

7. The child safety seat assembly according to claim 6, wherein the sidewalls on the base obstruct the third anchoring slot in each of the two rail portions when the seat is in the erected position relative to the base.

8. The child safety seat assembly according to claim 6, wherein the sidewalls on the base obstruct the second anchoring slot in each of the two rail portions when the seat is in the reclined position relative to the base.

9. The child safety seat assembly according to claim 6, wherein the sidewalls define two recessed portions adapted to respectively receive the rail portions therein, each recessed portion being delimited between two of the sidewalls.

10. The child safety seat assembly according to claim 9, wherein the rail portions are movable through the recessed portions when the seat is adjusted between the erected and reclined position relative to the base.

11. The child safety seat assembly according to claim 6, wherein the first, second and third anchoring slots respectively extend in a transversal direction from left to right through each of the rail portions.

12. A child safety seat assembly comprising:

a base; and

a seat movably assembled with the base, the seat having at least one anchoring slot adapted to retain a portion of a safety belt;

wherein the seat is movably adjustable relative to the base between a first state in which the anchoring slot is obstructed to block passage of the safety belt through the anchoring slot, and a second state in which the anchoring slot is opened to allow passage of the safety belt through the anchoring slot.

13. The child safety seat assembly according to claim 12, wherein the anchoring slot is obstructed by the base in the first state.

14. The child safety seat assembly according to claim 12, wherein the anchoring slot is located at a bottom of the seat, and the base has at least one protruding sidewall that obstructs the anchoring slot when the seat is in the first state.

15. The child safety seat assembly according to claim 14, wherein the first state corresponds to an erected position of the seat relative to the base, and the second state corresponds to a reclined position of the seat relative to the base.

16. The child safety seat assembly according to claim 12, wherein the seat has a backrest, the anchoring slot is located at a lower side of the backrest, and the base has at least one protruding sidewall that obstructs the anchoring slot when the seat is in the first state.

17. The child safety seat assembly according to claim 16, wherein the first state corresponds to a reclined position of the seat relative to the base, and the second state corresponds to an erected position of the seat relative to the base.

18. A child safety seat assembly comprising:

a base; and

a seat assembled with the base, the seat having at least a first anchoring slot and a second anchoring slot spaced apart from each other and respectively adapted to retain a portion of a safety belt, and the seat being adjustable relative to the base between a first position and a second position;

wherein each of the first and second anchoring slots alternates between an obstructed state where passage of the safety belt through the slot is blocked, and an opened state where passage of the safety belt through the slot is allowed, when the seat is adjusted between the first and second positions.

19. The child safety seat assembly according to claim 18, wherein the seat has a backrest, the first anchoring slot is located at a bottom of the seat, the second anchoring slot is located at a lower side of the backrest, and the base has one or more protruding wall configured to selectively obstruct the first and second anchoring slots.

20. The child safety seat assembly according to claim 19, wherein the base obstructs the first anchoring slot and leaves the second anchoring slot accessible for passage of the safety belt when the seat is in an erected position relative to the base, and the base leaves the first anchoring slot accessible for passage of the safety belt and obstructs the second anchoring slot when the seat is in a reclined position relative to the base.
