When children are buckled up with the vehicle seat belt, they often feel that the shoulder belt is 'uncomfortable', leading to a risk of positioning the shoulder belt incorrectly to avoid discomfort, e.g. by placing it underneath their arm. To avoid this risk of misuse and to increase comfort, the PAD+ softens the edge of the vehicle seat belt, padding it. Additionally, it also actively increases safety by acting as a cushioning bumper between the child's chin and chest.
