Abstract
The child restraint system comprises a harness that extends through one of a plurality of slots in the shell for restraining a child occupant within the child restraint system, and a control unit for determining whether the harness is properly adjusted based upon the size of the child. Belt location sensors are disposed at the slots to detect the presence of a harness belt. The child restraint system also includes temperature sensors responsive to body temperature of the child. The control unit processes the signals from the belt location sensors and the proximity sensors and issues an alert signal if the belt location is not the recommended belt location based upon the size of the child.
