hi there,
some cars have an option to disarm the airbag if a child is seated front, or if an infant is in a carseat in front. some cars dont have this as standard, but this disarm switch is an extra.
if an infant is in a rear facing car seat,belted to a front seat, what hazard would an airbag deployment pose?the bag would just hit (or cushion) the back of the infant car seat.
e.g.:
