Abstract

A child booster seat assembly includes a base seat and an upper seat. A first seating area is formed on the base seat. The upper seat is detachably installed on the base seat. The upper seat can be installed on the base seat installed on an adult chair at a higher position or detached from the base seat and installed on the adult chair at a lower position, which allows a caregiver to adjust an elevated height of the upper seat easily. Furthermore, when the upper seat is detached from the base seat, the upper seat and the base seat can be used independently and respectively installed on two adult chairs for accommodating two children at once.

First claim

What is claimed is:

1. A child booster seat assembly comprising:
a base seat whereon a first seating area is formed; and
an upper seat whereon a second seating area is formed, the upper seat being detachably installed on the base seat, at least one first guiding structure and at least one second guiding structure being formed on the upper seat and the base seat respectively, the at least one first guiding structure and at least one second guiding structure being a key and a keyway respectively, the at least one first guiding structure and the at least one second guiding structure cooperating with each other for guiding the upper seat to be aligned with the base seat when the upper seat is installed on the base seat and the at least one first guiding structure being for supporting the upper seat on an adult chair when the upper seat is detached from the base seat and placed on the adult chair.

2. The child booster seat assembly of claim 1 , further comprising a latch mechanism for latching the upper seat on the base seat.

3. The child booster seat assembly of claim 2 , wherein the latch mechanism comprises:
an actuator disposed on the upper seat;
at least one first engaging structure disposed on the upper seat and connected to the actuator; and
at least one second engaging structure disposed on the base seat and located at a position corresponding to the at least one first engaging structure for engaging with or disengaging from the at least one first engaging structure.

4. The child booster seat assembly of claim 3 , wherein the at least one second guiding structure is located at a position corresponding to the at least one first guiding structure.

5. The child booster seat assembly of claim 4 , wherein the at least one first engaging structure is movably disposed on the at least one first guiding structure, the at least one second engaging structure is formed inside the at least one second guiding structure, and the at least one first engaging structure and the at least one second engaging structure are engaged with each other to restrain separation of the upper seat from the base seat.

6. The child booster seat assembly of claim 5 , wherein the actuator is a button, the at least one first engaging structure is a latch, the at least one second engaging structure is an indentation.

7. The child booster seat assembly of claim 1 , wherein the upper seat comprises a seat bottom and a seat back pivotally disposed on the seat bottom.

8. The child booster seat assembly of claim 7 , wherein at least one pivoting boss protrudes from the seat back, at least one through slot is formed on the seat bottom, and the at least one pivoting boss rotatably passes through the at least one through slot.

9. The child booster seat assembly of claim 8 , wherein the at least one pivoting boss comprises a flange, the seat bottom comprises a bottom body, the at least one through slot is formed on the bottom body and extends along a vertical direction, a diameter of an upper end of the at least one through slot is greater than a diameter of a lower end of the at least one through slot, the diameter of the upper end of the at least one through slot is greater than a diameter of the flange for allowing the flange to pass through the upper end of the at least one through slot, the diameter of the lower end of the at least one through slot is less than the diameter of the flange for restraining the flange from passing through the lower end of the at least one through slot, the at least one pivoting boss rotatably engages with the lower end of the at least one through slot about a pivoting axis of the seat back relative to the seat bottom.

10. The child booster seat assembly of claim 9 , wherein the seat bottom further comprises at least one side panel detachably installed on the bottom body, a retention boss protrudes from the at least one side panel for rotatably and at least partially inserting into the at least one pivoting boss, and the retention boss restrains the at least one pivoting boss from moving relative to the at least one through slot when the retention boss is rotatably and at least partially inserted into the at least one pivoting boss.

11. The child booster seat assembly of claim 7 , wherein the seat back comprises an upper portion and a lower portion, the lower portion is pivotally disposed on the seat bottom, and the upper portion is detachably installed on the lower portion.

12. The child booster seat assembly of claim 1 , further comprising:
at least one webbing strap connected to the upper seat for attaching the upper seat onto the adult chair; and
at least one chamber structure located adjacent to a bottom portion of the upper seat, the at least one chamber structure comprising an uncovered opening, and the at least one webbing strap being accommodated inside the at least one chamber structure through the uncovered opening.

13. The child booster seat assembly of claim 12 , wherein the upper seat comprises a seat bottom, the seat bottom comprises a bottom body and at least one side panel detachably installed on the bottom body, and the at least one chamber structure is integrated with the at least one side panel.

14. The child booster seat assembly of claim 12 , wherein the uncovered opening is oriented horizontally toward a center of the bottom portion of the upper seat.

15. The child booster seat assembly of claim 1 , wherein the upper seat further comprises a harness system for securing a child on the upper seat.

16. The child booster seat assembly of claim 1 , further comprising a tray detachably disposed on the upper seat.

17. The child booster seat assembly of claim 1 , further comprising a seat cushion whereon a third seating area is formed, the seat cushion being detachably disposed on the upper seat, and the third seating area being less than the second seating area.

18. The child booster seat assembly of claim 1 , wherein the second seating area is less than the first seating area.

19. A child booster seat assembly comprising:
a base seat whereon a first seating area is formed; and
an upper seat whereon a second seating area is formed, the upper seat being detachably installed on the base seat, at least one first guiding structure and at least one second guiding structure being formed on the upper seat and the base seat respectively, the at least one first guiding structure being a key protruding from a rear bottom portion of the upper seat, the at least one second guiding structure being a keyway formed on a side wall of the base seat, the at least one first guiding structure and the at least one second guiding structure cooperating with each other for guiding the upper seat to be aligned with the base seat when the upper seat is installed on the base seat, and the at least one first guiding structure being for supporting the upper seat on an adult chair when the upper seat is detached from the base seat and placed on the adult chair.
