(1) Their developing bodies are more fragile, and
(2) They often stand on the seat or sit in an adults' lap, which increase the danger of injury or death in a collision.
In order to survive a crash, children, just like adults need the impact forces weed over the strongest parts of their bodies. Adult seat belts cannot offer this protection to the fragile and undersized body of a young child. Only a properly designed seat for children will afford this protection.
Babies weighing less than twenty pounds (nine kg) and unable to sit upright by themselves are best protected by a child restraint designed for infants. These seats face the rear of the car and carry the child in a reclining position. The seat is anchored to the car with an adult lap belt. With some newer cars a special clip is required to adapt the seat belt so that it provides positive anchorage for this type of child restraint. Consult the owner's manual and acquire the correct clip from your dealer. Follow installation instructions exactly. Some
Seats are adaptable to the age of the child, converting to a front facing child restraint when the child reaches twenty pounds.
Children weighing between twenty and forty pounds (nine and eighteen kg) should ride protected by either of two basic types of child restraint. Both face the child forward in the vehicle and both are anchored to the vehicle by the adult lap belt.
The most common type of restraint uses a five point safety harness to spread the forces of impact and keep the child safely in the seat. A top anchor strap, which prevents the top of the restraint from rotating forward on impact, is an important feature of this seat. It must be fastened securely to the interior of the car exactly as described in the manufacturer's instructions.
The other type of child restraint uses a protective shield as part of the seat. This type of seat anchors to the vehicle with the adult lap belt only and for this reason is adaptable to a wide variety of vehicles.
Children weighing over forty pounds (eighteen kg) can use adult lap belts when they outgrow their child restraints. Special care must be taken to position the child with the lap belt fitting snug and low on the hips. |
