Patent ID: 8585063

Claim:
A child carrier apparatus comprising: a support frame; a backrest assembly having a backrest frame; a seat assembly mounted with the support frame, wherein the seat assembly includes a first seat frame and a second seat frame, the second seat frame being operable to rotate about a pivot axis relative to the first seat frame between a deployed state for allowing sitting on the second seat frame, and a folded state disabling sitting on the second seat frame; and a hinge structure connected between the backrest frame and the first seat frame and including a latch element; wherein the latch element is operable to lock the backrest frame in a first position when the second seat frame is in the deployed state, and a rotation of the second seat frame from the deployed state to the folded state drives the latch element in movement to unlock the backrest frame such that the backrest frame is allowed to rotate from the first position to a second position; and wherein the second position of the backrest frame allows sitting on the first seat frame and creates a blocking interference that keeps the second seat frame in the folded state.
