Child restraint

1. A child restraint comprising a seat base adapted to be secured to a vehicle seat, the seat base comprising a seat-base foundation formed to include a vehicle seatbelt path, a vehicle seatbelt retainer coupled to the seat-base foundation and configured to pivot between a released position spaced away from the vehicle seatbelt path and a clamped position overlying the vehicle seatbelt path to clamp a vehicle seat belt to the seat-base foundation to secure the seat base to the vehicle seat, and a seat-orientation controller coupled to the seat-base foundation and movable relative to the seat-base foundation and the vehicle seatbelt retainer about a vertical rotation axis between a first position in which the seat-orientation controller overlies the vehicle seatbelt retainer and blocks the vehicle seatbelt retainer from moving from the clamped position to the released position, and a second position, in which the vehicle seatbelt retainer is exposed and is moveable between the clamped position and the released position, a juvenile seat coupled to the seat-orientation controller for movement therewith relative to the seat-base foundation and to the vehicle seatbelt retainer, and a seat connection system configured to maintain connection between the juvenile seat and the seat-orientation controller, wherein the juvenile seat is movable relative to the seat base between a use position in which the juvenile seat is installed on the seat-orientation controller to rotate about the vertical rotation axis with the seat-orientation controller, and a base-installation position, in which the juvenile seat is spaced apart from the seat-orientation controller while the seat-orientation controller is in the second position so that the vehicle seatbelt retainer is free to pivot between the released position and the clamped position.

2. The child restraint of claim 1 , wherein the seat connection system includes a hinge interconnecting the juvenile seat and the seat-orientation controller and the juvenile seat is pivotable relative to the seat-orientation controller about a hinge axis between the use position and the base-installation position.

3. The child restraint of claim 2 , wherein the hinge is coupled to a rear end of the seat-orientation controller and a rear end of the juvenile seat.

4. The child restraint of claim 2 , wherein the hinge is force-assisted to control pivoting of the juvenile seat from the base-installation position to the use position or from the use position to the base-installation position.

5. The child restraint of claim 4 , wherein the hinge is spring-loaded.

6. The child restraint of claim 4 , wherein the hinge is gas-assisted.

7. The child restraint of claim 2 , wherein the seat connection system further includes a seat support coupled to a front end of the seat-orientation controller and pivotable between a stowed position, in which the seat support is substantially flush with an upper surface of the seat-orientation controller so that the juvenile seat can assume the use position, and a support position, in which the seat support extends away from the upper surface of the seat-orientation controller and a distal end of the seat support engages the juvenile seat to support the juvenile seat in the base-installation position.

8. The child restraint of claim 7 , wherein the seat support includes a rigid strip such that the seat support is in compression while supporting the juvenile seat in a tilted position.

9. The child restraint of claim 7 , wherein the seat support includes a flexible strip to support the juvenile seat in a tiled position such that the seat support is in tension while supporting the juvenile seat in a tilted position.

10. The child restraint of claim 2 , wherein the hinge is coupled to a front end of the seat-orientation controller and a front end of the juvenile seat.

11. The child restraint of claim 10 , wherein the seat connection system further includes a seat support coupled to a rear end of the seat-orientation controller and pivotable between a stowed position, in which the seat support is substantially flush with an upper surface of the seat-orientation controller so that the juvenile seat can assume the use position, and a support position, in which the seat support extends away from the upper surface of the seat-orientation controller and a distal end of the seat support engages the juvenile seat to support the juvenile seat in the base-installation position.

12. The child restraint of claim 1 , wherein the seat connection system includes a first seat support coupled near a front end of the seat-orientation controller and a rear end of the juvenile seat and a second seat support coupled near a rear end of the seat-orientation controller and a front end of the juvenile seat.

13. The child restraint of claim 12 , wherein the first and second seat supports cross near a center of each of the first and second seat supports at a central pivot axis, and wherein both the first and second seat supports pivot relative to the seat base and the juvenile seat and relative to each other about the central pivot axis when the juvenile seat is lifted upwardly away from the seat base from the use position to the base-installation position.

14. The child restraint of claim 1 , wherein the vehicle seatbelt retainer is blocked from moving to the released position when the juvenile seat is in the use position and the seat-orientation controller is in the second position.

15. A child restraint comprising a seat base adapted to be secured to a vehicle seat, a juvenile seat coupled to the seat base, and a seat connection system configured to maintain connection between the juvenile seat and the seat base, wherein the juvenile seat is movable relative to the seat base between a use position in which the juvenile seat is installed on the seat base in a forward-facing orientation or a rearward-facing orientation, and a base-installation position, in which the juvenile seat is spaced apart from the seat base while connected to the seat base by the seat connection system; wherein the seat connection system includes a hinge interconnecting the juvenile seat and the seat base and the juvenile seat is pivotable relative to the seat base about a hinge axis between the use position and the base-installation position, and wherein the hinge is coupled to a rear end of the juvenile seat.

16. The child restraint of claim 15 , wherein the hinge is force-assisted to control pivoting of the juvenile seat from the base-installation position to the use position or from the use position to the base-installation position.

17. The child restraint of claim 15 , wherein the seat connection system includes a first seat support coupled near a rear end of the juvenile seat and a second seat support coupled near a front end of the juvenile seat.

18. The child restraint of claim 17 , wherein the first and second seat supports cross near a center of each of the first and second seat supports at a central pivot axis, and wherein both the first and second seat supports pivot relative to the seat base and the juvenile seat and relative to each other about the central pivot axis when the juvenile seat is lifted upwardly away from the seat base from the use position to the base-installation position.

19. A child restraint comprising a seat base adapted to be secured to a vehicle seat, a juvenile seat coupled to the seat base, and a seat connection system configured to maintain connection between the juvenile seat and the seat base, wherein the juvenile seat is movable relative to the seat base between a use position in which the juvenile seat is installed on the seat base in a forward-facing orientation or a rearward-facing orientation, and a base-installation position, in which the juvenile seat is spaced apart from the seat base while connected to the seat base by the seat connection system; wherein the seat connection system includes a hinge interconnecting the juvenile seat and the seat base and the juvenile seat is pivotable relative to the seat base about a hinge axis between the use position and the base-installation position, and wherein the hinge is coupled to a front end of the juvenile seat.
