Cradle with strap tension detectors

The cradle has an alarm generating unit generating an alarm based on the analysis of electric signals. The unit does not generate the alarm if the child is not present in a vehicle, and does not generate the alarm if the child is present in the vehicle and if the handling of connection elements (12g, 12d) is not carried out. The unit does not generate the alarm if the child is present in the vehicle and if one element is unbend for short time gap, and does not generate the alarm during time gap after detection of the child presence. The unit generates ongoing/partial installation signal. The connection elements include Isofix(RTM: attachment points for child safety seats in passenger cars) clips connected to rings connected to the vehicle, and linking strap portions (13d, 13g) e.g. Fixauto(RTM: Not defined) connected to the cradle.
