Abstract

Claims (38)

1. An infant transport system, comprising:

a base;

a chassis releasably coupled to the base via a first release mechanism; and

an infant car seat releasably coupled to the chassis via a second release mechanism;

wherein the chassis comprises a frame, a pair of rear legs pivotally coupled to the frame and a pair of front legs, each front leg pivotally coupled to a respective rear leg, wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition when the chassis and infant car seat are released from the base;

wherein the chassis is intermediate the base and the infant car seat in the first transport condition;

wherein the chassis includes a rod, and wherein the first release mechanism and the second release mechanism are each releasably coupled to the rod in the first transport condition;

wherein the chassis and the infant car seat are releasable from the base as a combined unit upon operation of the first release mechanism; and

wherein the infant car seat is releasable from the combined unit of the base and chassis upon operation of the second release mechanism.

2. The system of claim 1 , wherein the rod on the chassis is continuous and extends from one side of the chassis to an opposite side of the chassis.

3. The system of claim 1 , wherein the rod on the chassis is discontinuous and includes multiple segments.

4. The system of claim 1 , wherein any of the infant car seat, a combination of the chassis and the infant car seat, and a combination of the base, the chassis and the infant car seat, are configured to be installed in an automobile.

5. The system of claim 1 , wherein each of the front legs and each of the rear legs have a wheel at a respective distal end, and wherein the second transport condition is usable as a stroller.

6. The system of claim 5 , wherein the frame of the chassis includes a pair of recesses, and wherein the rear wheels are removable from the rear legs and stow-able in the pair of recesses.

7. An infant transport assembly, comprising:

a base having a first end and a second end;

an independent chassis releasably coupled to the base via a first release mechanism, wherein the chassis comprises a frame, a pair of rear legs pivotally coupled to the frame and a pair of front legs, each front leg pivotally coupled to a respective rear leg, wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition when the chassis and infant car seat are released from the base; and

an infant car seat releasably coupled to the chassis via a second release mechanism, the infant car seat having a toe end and a head end distal from the toe end;

wherein the infant car seat is releasable from the combined unit of the base and chassis upon operation of the second release mechanism; and

wherein the chassis includes a rod, and wherein the first release mechanism and the second release mechanism are each releasably coupled to the rod in the first transport condition.

8. The assembly of claim 7 , wherein the chassis and the infant car seat are releasable from the base as a combined unit upon operation of the first release mechanism.

9. The assembly of claim 8 , wherein the chassis is intermediate the infant car seat and the base in a first transport condition with the first release mechanism and the second release mechanism coupled to the rod, and wherein the rod on the chassis is proximate the first end of the base and proximate the toe end of the infant car seat in the first transport condition.

10. The assembly of claim 9 , wherein the infant car seat comprises a tower coupling latch between the toe end and the head end, the tower coupling latch configured to allow the infant car seat to be releasably coupled to an alternative transport structure.

11. The assembly of claim 10 , wherein any of the infant car seat, a combination of the chassis and the infant car seat, and a combination of the base, the chassis and the infant car seat, are configured to be installed in an automobile.

12. The assembly of claim 11 , wherein the first end of the base comprises an upwardly extending rebound panel, and a level indicator on an upper portion of the rebound panel.

13. The assembly of claim 12 , wherein each of the front legs and each of the rear legs have a wheel at a respective distal end, and wherein the frame of the chassis includes a pair of recesses, and wherein the rear wheels are removable from the rear legs and stow-able in the pair of recesses when in the first transport condition.

14. A system to transport infant children, comprising:

a base configured to be secured to a portion of an automobile;

a chassis independent from the base, wherein the chassis comprises a frame, a pair of rear legs pivotally coupled to the frame and a pair of front legs, each front leg pivotally coupled to a respective rear leg, wherein each of the front legs and each of the rear legs have a wheel at a respective distal end, wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition when the chassis and infant car seat are released from the base;

a first release mechanism releasably coupling the chassis to the base;

an infant car seat independent from the base and the chassis;

a second release mechanism releasably coupling the infant car seat to the chassis;

wherein the chassis and the infant car seat are releasable from the base as a combined unit upon operation of the first release mechanism;

wherein the infant car seat is releasable from the combined unit of the base and chassis upon operation of the second release mechanism, and

wherein the frame of the chassis includes a pair of recesses, and wherein the rear wheels are removable from the rear legs and stow-able in the pair of recesses.

15. The system of claim 14 , wherein the chassis comprises a first handle coupled to the first release mechanism and configured to move the first release mechanism to selectively release the chassis and infant car seat as a unit from the base.

16. The system of claim 15 , wherein the infant car seat comprises a second handle coupled to the second release mechanism and configured to move the second release mechanism to selectively release the infant car seat from the chassis and the base.

17. The system of claim 16 , wherein the first release mechanism and the second release mechanism are spring-loaded to a closed configuration.
