Seating and safety restraints To improve the fit of lap and shoulder belts on children who have outgrown child safety seats, Ford recommends use of a belt positioning booster seat that is labelled as conforming to all Federal motor vehicle safety standards. Belt positioning booster seats raise the child and provide a shorter, firmer seating cushion that encourages safer seating posture and better fit of lap and shoulder belts on the child. A belt positioning booster seat should be used if the shoulder belt rests in front of the child's face or neck, or if the lap belt does not fit snugly on both thighs, or if the thighs are too short to let the child sit all the way back on the seat cushion when the lower legs hang over the edge of the seat cushion. You may wish to discuss the special needs of your child with your pediatrician. 110
