摘要:
A child restraint system includes an electronic control unit having an event data recorder for storing data relating to proper adjustment or installation of the child restraint system. The control unit receives an electrical signal from one or more sensors mounted on the child seat and determines conditions of the child seat based upon the value of the property indicated by the signal. The event data recorder is configured to store the resulting data and to allow the stored data to be retrieved in response to an inquiry. Thus, in the event of a vehicle accident or other incident, the electronic control unit may be connected to an external diagnostic unit, and the relevant data may be downloaded to the diagnostic unit for evaluation.
摘要:
A child restraint system for transporting a child within an automotive vehicle includes a weight sensor for determining the weight of the child and compares the child's weight to a recommended weight range. The weight sensor is disposed within a cushion that lines a shell and provides an electrical signal to a control unit. The control unit processes the electrical signal and provides an alert signal when the weight is not within the recommended range. Also, the child restraint system may include a second sensor for sensing a condition that depends upon the child's weight such as directional orientation or angular orientation of the child restraint system, or location or tension of a vehicle seat belt or tether that secures the child restraint system within the vehicle, or the location or tension of a harness for restraining the child occupant within the child restraint system.
