ABSTRACT:
A child restraint warning system configured to be secured to a child seat/carrier having a base, a seat detachably connected to the base, where the child seat/carrier includes a harness configured to be releasably secured with a latch. When the seat is secured on the base a seat position sensor sends a signal to a control unit positioned on the back of the seat. The control unit is switched into an active status for detecting an unlocked condition of the harness latch. A first series of audible warning signals is produced by the control unit if the latch remains unlocked for a pre-determined period of time. If the latch continues to be in an unlocked condition after the first series of warning signals the control unit generates a second series of signals, which can be spoken messages pre-programmed by the user.
