Abstract
A child restraint system and a method for monitoring installation of the child restraint system are provided. The child restraint system includes a child seat configured to receive a child occupant. The child seat has at least a first seat belt guide member configured to engage a vehicle seat belt webbing for securing the child seat to a vehicle seat. The child restraint system further includes a first sensor coupled to the first seat belt guide member. The first sensor is configured to output a first signal indicative of an amount of tension being applied to the vehicle seat belt webbing. The child restraint system further includes a controller coupled to the child seat configured to receive the first signal and to compute a first tension value based on the first signal. The controller further is configured to induce a first device disposed on the child seat to indicate when the first tension value is less than a predetermined tension value.
