1. A child transport carrier, comprising:

a lower frame member having a forward end and a rear end;

an upper frame member having a forward end and a rear end;

a forward frame member coupling the forward end of the lower frame to the forward end of the upper frame; and

a rear frame coupling the rear end of the lower frame member to the rear end of the upper frame member, the rear frame comprising:

a lower rear frame member having a lower end coupled to the rear end of the lower frame member, and

an upper rear frame member having an upper end coupled to the rear end of the upper frame member, and

a first joint assembly coupling the lower rear frame member and the upper rear frame member,

wherein the rear frame is configured to fold between an unfolded in-use position and a folded storage position, and

wherein an exterior angle formed by the lower rear frame member and the upper rear frame member is less than 180 degrees in the unfolded in-use position.

2. The carrier of claim 1 , wherein the exterior angle formed by the lower rear frame member and the upper rear frame member is less than 175 degrees.

3. The carrier of claim 1 , wherein the lower rear frame member and the upper rear frame member are prevented from pivoting with respect to each other when the carrier is in the unfolded in-use position.

4. The carrier of claim 1 , wherein the first joint assembly is disposed longitudinally forward of the rear end of the upper frame member in the unfolded in-use position.

5. The carrier of claim 4 , wherein the first joint assembly is disposed longitudinally rearward of the forward end of the upper frame member in the unfolded in-use position.

6. The carrier of claim 4 , wherein the first joint assembly is disposed longitudinally rearward of the rear end of the lower frame member in the unfolded in-use position.

7. The carrier of claim 5 , wherein the first joint assembly is disposed longitudinally forward of the forward end of the upper frame member in the folded storage position.

8. The carrier of claim 1 , wherein the first joint assembly is configured to move toward the forward end of the lower frame member when transitioning from the unfolded in-use position to the folded storage position.

9. The carrier of claim 1 , wherein an interior angle between the upper frame member and the upper rear frame member is fixed.

10. The carrier of claim 1 , wherein an interior angle between the upper frame member and the upper rear frame member is less than 90 degrees.

11. The carrier of claim 1 , further comprising:

a second joint assembly rotatably coupling an upper end of the forward frame member and the forward end of the upper frame member.

12. The carrier of claim 11 , wherein the second joint assembly is a non-locking joint.

13. The carrier of claim 11 , wherein an interior angle between the forward frame member and the upper frame member is fixed when the carrier is in the unfolded in-use position.

14. The carrier of claim 13 , wherein the interior angle between the forward frame member and the upper frame member is greater than 90 degrees when the carrier is in the unfolded in-use position.

15. The carrier of claim 14 , wherein the interior angle between the forward frame member and the upper frame member is 90 degrees when the carrier is in the folded storage position.

16. The carrier of claim 11 , wherein the upper frame member is configured to pivot about the second joint assembly when the carrier is transitioning from the unfolded in-use position to the folded storage position.

17. The carrier of claim 11 , wherein the upper frame member is configured to pivot about the second joint assembly and configured to move toward the forward end of the lower frame member when transitioning from the unfolded in-use position to the folded storage position.
